    Degassing tank and motor vehicle comprising such a tank
    The present invention relates to a degassing tank, adapted to equip a cooling system of a motor vehicle. The invention also relates to a motor vehicle equipped with a cooling system comprising such a degassing tank.
    In a conventional manner, a vehicle cooling system comprises a heat transfer fluid circuit formed by different pipes, also called hoses, which extend in the vicinity of the motor and the radiator of the motor vehicle. The system further comprises a degassing tank, also called expansion tank, defining an interior volume for receiving the coolant to be degassed. The flow of heat transfer fluid flowing in the degassing tank can be up to about 8 liters per minute (l / min).
    In practice, the degassing tank has two main functions. The first is to allow thermal expansion of the coolant, adding a volume of air above the maximum level of liquid in the tank. The second is to degas the heat transport circuit. Indeed, if the circuit is gas-free before the first commissioning of the vehicle, there is a risk of gassing of the circuit when the vehicle is in service, for example due to possible slight leaks at the inlet of the pump. water, wear of the cylinder head gasket or possible hot spots in the engine. Thus, by diverting the heat transfer fluid to the degassing tank, it can be degassed.
    In the case of a specific cooling system adapted to another part of the vehicle whose operating temperature is lower than that of the engine itself, for example the battery, the volume of the degassing tank is reduced in order to take account of this operating temperature is lower. The coolant can be circulated by an electric pump, so that the flow of heat transfer fluid flowing in the cooling system can rise above 15 l / min.
    In this situation, if it is expected that the entire flow of heat transfer fluid through the degassing tank, an undesirable effect of gassing of the heat transfer fluid is likely to occur at the outlet of degassing tank due to the low volume of this last and turbulence induced by the large flow. In addition, this configuration is likely to generate noise, especially in the case where the need for cooling is high, so that the heat transfer fluid flow is high. Thus, such a cooling system is relatively noisy and its degassing tank inefficient, especially if it equips a low-temperature secondary cooling circuit of an internal combustion engine, or a cooling circuit of battery power supply. an electric motor, in the case of a motor vehicle with electric traction.
    To overcome these disadvantages, it could provide a bypass pipe by "bypass" heat transfer fluid mounted in bypass of the degassing tank, so that only a fraction of this flow passes through the degassing tank. However, the installation of such a hose would induce additional costs of manufacture and assembly of the hose and increase the size of the cooling system. In addition, such a configuration would increase the risk of breakdowns, insofar as the bypass hose or "bypass" and its connection means would be subject to leakage. The invention therefore aims to remedy the aforementioned drawbacks and relates to a new degassing tank which is at the same time reliable, compact, low noise, efficient and easy to manufacture and to assemble. The invention relates to a degassing tank for a cooling system of a motor vehicle, the degassing tank comprising a main wall, which defines an internal degassing volume of the degassing tank, the main wall comprising a bottom and a opposite cowl, means for admitting a coolant to be degassed within the internal degassing volume and means for discharging the degassed heat transfer fluid out of the internal degassing volume. According to the invention, the degassing tank further comprises a coolant pipe, which passes through the hood and the bottom and comprises an internal section extending within the internal degassing volume from the hood to the bottom and of which an interior volume is separated from the internal degassing volume.
    Thanks to the invention, only a fraction of the heat transfer fluid flow is conducted in the internal degassing volume of the degassing tank to be degassed, the other fraction passing into the inner section without being degassed. The internal section thus constitutes a bypass or "built-in bypass" inside the tank to reduce the flow of fluid admitted into the internal degassing volume of the latter, which makes it possible to avoid any undesirable effect of engazage and to reduce the noise, without complicating the assembly and manufacture, nor generate excessive congestion. In addition, the inner section being disposed inside the degassing tank which is itself sealed, it does not imply an additional risk of leakage, so that the tank is particularly reliable.
    According to other advantageous features of the invention, taken separately or in combination: the inner section is of tubular shape and has a cross section which defines an outer perimeter, the inner section being separated from the main wall on at least the three quarter of the outer perimeter. - The inner section comprises: o an upper tube, which comprises a first end, the upper tube extending within the internal degassing volume from the hood to the first end, and o a lower tube, which comprises a second end, the lower tube extending into the interior degassing volume from the bottom to the second end, the upper tube and the lower tube being connected to each other via the first end and from the second end. - The upper tube comes from material with the cover, and the lower tube comes from material with the bottom, the cover being attached to the bottom. - The inner section comprises means for sealing connection between the first end and the second end. - The intake means comprise: a transfer orifice, which is formed in the inner portion in the vicinity of the hood, o a dispensing orifice, which opens into the internal degassing volume in the vicinity of the bottom, o a pipe of supply, which connects the transfer port to the dispensing orifice. - The feed pipe comprises: o an intermediate bend, which is arranged in the vicinity of the hood, o a transfer tube, which connects the transfer port to the intermediate bend and which has a cross section whose diameter is less than one. cross section of the inner section, and o a dip tube, which extends from the intermediate bend to the dispensing orifice. - The evacuation means comprise: o a discharge orifice, which is formed in the bottom, and o a discharge pipe, which connects the discharge orifice to the pipe outside the internal degassing volume. - The degassing tank comprises a partition interposed between the intake means and the discharge means in the internal degassing volume. The invention also relates to a motor vehicle comprising a cooling system of one or more members of the vehicle, the system itself comprising a coolant circuit and a coolant degassing tank as described above. The invention will be better understood on reading the following description, given solely by way of nonlimiting and non-exhaustive example and with reference to the drawings in which: FIG. 1 is a top view of a degassing tank according to the invention, - Figure 2 is a side view of the degassing tank of Figure 1, - Figure 3 is a section along the line of section III-III of Figure 2, and - The FIG. 4 is a section along section line IV-IV of FIG.
    The degassing tank 1 shown in Figures 1 to 4 is designed to be integrated in a coolant fluid network of a motor vehicle. In particular, this degassing tank 1 can be integrated in the heat transfer fluid circuit of one or more elements whose operating temperature is lower than that of a motor vehicle engine. For example, the tank 1 is adapted to equip a cooling system of a battery or other body such as a vehicle heat exchanger, this cooling system itself comprising a coolant circuit arranged in the vicinity of the battery or the body in question and in the vicinity of a vehicle radiator. The battery in question may be a conventional battery associated with a heat engine of the vehicle, or a main battery supply of an electric motor of the vehicle, in the case where the vehicle is a hybrid vehicle, or a vehicle called " "electric vehicle", that is to say a vehicle whose traction is provided by an electric motor and not a heat engine. Alternatively, the tank 1 can equip a cooling system of a heat engine, and in particular a secondary low temperature circuit. The vehicle considered here is for example a car, a bus, a coach or a truck, that is to say a land vehicle. Alternatively, this vehicle may be a marine vehicle of the motorboat son-in-law, an aerial vehicle of the powered aircraft type, or a railway vehicle. The heat transfer fluid used in the cooling system and in the tank 1 is for example a cooling liquid, such as glycol water. Depending on the application of the degassing tank 1, any known and suitable coolant fluid can be implemented.
    The tank 1 comprises a main wall 3 which forms a tank and defines an internal degassing volume V of the tank 1 provided for the degassing of the coolant. The wall 3 is preferably made of molded plastic material, and comprises two main parts joined together, namely: - a bottom 5, which forms a lower part of the main wall 3 and defines the bottom of the interior volume degassing V, and - a cover 7, which forms an upper portion of the wall 3 and defines the top of the internal degassing volume V.
    For convenience, the present description is oriented with respect to FIG. 2, considering that the terms "upper" and "high" correspond to an axial direction turned towards the upper part of FIG. 2, and in this case in the direction of the cover 7, while the terms "lower" and "bottom" correspond to an axial direction of opposite direction, in this case oriented towards the bottom 5. In effect, in operation, the reservoir 1 is designed to be arranged in the orientation of Figure 2, that is to say that the cover 7 is located plumb and above the bottom 5, so that the gravity is substantially vertically oriented from top to bottom on the Figure 2. The cover 7 and the bottom 5 are thus disposed opposite one another within the tank 1.
    The bottom 5 forms a pocket with an upper edge 9 which delimits an upper part of the bottom 5 and surrounding a portion of the internal degassing volume V. The upper edge 9 extends in a plane. In the same way, the cover 7 comprises a lower edge 11 of corresponding shape with that of the upper edge 9 and surrounding the interior degassing volume V. The cover 7 also has a pocket shape that caps and closes the bottom 5 so that the bottom 5 and the cover 7 contain the internal degassing volume V. The cover 7 is preferably welded to the bottom 5, the edge 9 being welded to the edge 11. Other methods of assembling the cover 7 on the bottom 5 can be envisaged, since the cap 7 forms with the bottom 5 a sealed wall 3, which is adapted to contain the heat transfer fluid of the cooling system, the internal degassing volume V being the seat of a degassing of the heat transfer fluid .
    In a conventional manner, the internal degassing volume V is designed to receive a quantity of coolant which rests on the bottom 5. It is expected that the coolant reaches a nominal level N which is visible in FIG. 2, the part of the volume degassing interior V situated above the nominal level N constituting an expansion volume which is occupied by a gas, formed by degassing the coolant located in the part of the degassing interior volume V below the nominal level N, and only by air. The nominal level N is for example symbolized by a graduation formed on the wall 3, not shown. The coolant is contained in the volume V under pressure to promote its outgassing and is circulating, at least sequentially, during operation of the vehicle.
    The tank 1 also comprises a neck 13, which is arranged on the cover 7 and which defines an access opening 15, through the cover 7, to the internal degassing volume V. The neck 13 extends outside the hood the main wall 3 and protrudes upwards along an axis Z13 substantially orthogonal to the edges 9 and 11. The neck 13 is provided to receive a degassing valve not shown, which may for example be screwed to an external thread 17 of the neck 13 The access opening 15 is formed in the highest part of the cover 7 in consideration of the gravity.
    The reservoir 1 comprises a pipe 19 of heat transfer fluid, which is of tubular and bent shape, advantageously of circular cross section and substantially constant over the entire length of the pipe 19.
    The pipe 19 comprises an intake section 21 which extends along an axis X21 which is parallel to the plane of extension of the edges 9 and 11. The intake section 21 extends outside the volume degassing interior V and the main wall 3, and is connected thereto via the cover 7. The intake section 21 has an open coupling end 25 designed to be connected to a supply hose of the tank 1 heat transfer fluid, not shown. The pipe 19 also comprises a through section 23 extending the intake section 21 coaxially with the latter. The through section 23 passes through the cover 7 so as to be partly contained in the internal degassing volume V. In this case, an upper portion of the through section 23 extends outside the wall 3 and a lower portion extends inside the wall 3. The pipe 19 then comprises a bend 27 which defines a 90 ° angle with the section through 23.
    An inner section 29 of the pipe 19 extends along an axis X29 from the bend 27, so that the inner section 29 is perpendicular to the intake section 21 and the through section 23. The inner section 29 extends to within the internal degassing volume V from the cover 7 to the bottom 5, as can be seen in FIG. 4. The internal volume V29 of the internal section is separated from the internal degassing volume V.
    The pipe 19 further comprises a second elbow 31 which extends the section 29 from the bottom 5, outside the internal degassing volume V and the wall 3. The elbow 31 defines an obtuse angle. Thus, the pipe 19 also crosses the bottom 5 downstream of the inner section 29 and upstream of the elbow 31.
    The pipe 19 finally comprises a discharge section 33 which extends outside the main wall 3 along an axis X33 which is intersecting with the axis X29. The evacuation section 33 extends from the elbow 31. The pipe 19 also comprises a coupling end 35 which is open and which terminates the evacuation section 33 to allow the coupling of an evacuation hose. heat transfer fluid of the tank 1, which is not shown in the figures. The evacuation section 33 is oriented along the bottom 5 slightly obliquely to the plane defined by the edge 9 and the edge 11. The axes X21, X29 and X33 are oriented almost co-planarly, the intake section 21 and the discharge section 33 being directed substantially in the same direction, obliquely near the discharge section 33 mentioned above. In practice, the sections 21 and 33 diverge slightly from one another from the inner section 29, as can be seen in FIG. 3. In general, it can be considered that the pipe 19 has a U-shaped profile.
    In practice, the tank 1 is connected to the heat transfer fluid circuit of the cooling system via its coupling ends 25 and 35. The heat transfer fluid circulates in line 19 along the arrow F1, as illustrated. In this case, the heat transfer fluid is admitted into the intake section 21 and flows in the inner section 29 and then in the evacuation section 33.
    The inner section 29 has a rectilinear profile. The cross section of the section 29, that is to say a section defined orthogonally with respect to the axis X29, thus defines a substantially circular outer perimeter. The inner portion 29 is separated from the main wall 3 on at least three quarters of this outer perimeter, or even on the entire latter. In practice, the inner section 29 forms a tube whose cross section is substantially identical to the section of the section 21 and the section 33 which themselves form straight tubes. In particular, the sections 21, 29 and 33 are of the same diameter. The inner section 29 passes through the internal degassing volume V from top to bottom, passing close to the edges 9 and 11.
    The reservoir 1 comprises an upper tube 37, which itself comprises a first end 39, the upper tube 37 extending within the internal degassing volume V from the cover 7 to the first end 39. The upper tube 37 thus forming a first portion of the inner section 29. In the same way, the tank 1 comprises a lower tube 41, which itself comprises a second end 43, so that the lower tube 41 extends within the interior volume of degassing V from the bottom 5 to the second end 43. The tubes 37 and 41 are coaxial with the axis X29 and are connected to each other through their respective ends 39 and 43. As illustrated in FIG. 4, the upper tube 37 is threaded inside the lower tube 41. In this case, the outer circumference of the upper tube 37 is reduced from the first end 39 so that the latter can be inserted inside the second end 43 of the lower tube 41, the inner diameter of the lower tube 41 being, meanwhile, increased so that the first end 39 is accommodated in the lower tube 41. The first end 39 and the second end 43 and form a connection between the tubes 37 and 41. The outer diameter of the end 39 and the inner diameter of the second end 43 are preferably adjusted so that the upper tube 37 is connected to the tube lower 41 sealingly. The end 39 and the end 43 are nested so as to form a sealed connection between the tube 37 and the tube 41, so that the heat transfer fluid does not draw air through this connection. In a variant, sealing means may be provided to prevent any risk of leakage at this connection. In particular, the upper tube 37 may be welded to the lower tube 41 to seal the connection between the first end 39 and the second end 43.
    Preferably, the upper tube 37, as well as the intake section 21, the through section 23, the bend 27 and the coupling end 25, are made of material with the cover 7 and form an upper assembly of the tank 1 which can be made by molding or injection. Similarly, the lower tube 41 and the elbow 31, the discharge section 33 and the coupling end 35 are made of material with the bottom 5 so as to form a lower assembly of the tank 1 which can also be realized by molding or injection. The tank 1 is thus particularly easy and inexpensive to manufacture. This method of manufacture in two upper and lower sets reduces the risk of leakage, so that the tank 1 is particularly reliable and robust.
    The reservoir 1 also comprises a transfer orifice 45 which is visible in FIG. 4, and which is formed in the internal section 29, in particular in the tube 37, in the vicinity of the cover 7. The reservoir 1 also comprises a transfer tube 47 which extends from the transfer port 45 coaxially with the axis X21. This transfer tube 47 has a cross section whose diameter is smaller than that of the cross section of the inner section 29, and more generally of the pipe 19. The diameter of the transfer tube 47 is such that the flow rate of the coolant flowing in the internal section 29 and different from that flowing in the transfer tube 47. The dimensioning of the section 29 and the tube 47 adjusts the relative flow rates between the inner section 29 and the tank 1. The transfer tube 47 extends advantageously along the hood 7.
    The reservoir 1 then comprises an intermediate bend 49 which is arranged against the cover 7, or at least in the vicinity of the cover 7. The intermediate bend 49 extends the transfer tube 47, so that the latter connects the transfer port 45 at the intermediate elbow 49. The intermediate elbow 49 forms a right angle.
    The reservoir 1 further comprises a dip tube 51 which extends along an axis X 51 which is orthogonal to the axis X 21 and parallel to the axis X 29. The plunger tube 51 extends the elbow 49 in the direction of the bottom 5. The plunger tube 51 preferably has a cross section of diameter greater than that of the transfer tube 47, but nevertheless less than that of the inner section 29. The plunger tube 51 ends by a dispensing orifice 53 of the tank 1, which opens into the internal degassing volume V in the vicinity and away from the bottom 5. The plunger tube 51 thus extends from the intermediate bend 49 to the dispensing orifice 53, so that the lower part of the plunger tube 51 is located below the nominal level N so as to be immersed in the heat transfer fluid itself. Thus, the plunger tube 51 extends from the cover 7 at least beyond, that is to say below, the plane defined by the edges 9 and 11 and beyond, that is to say, say below, the nominal level N of the tank 1. The dispensing orifice 53 is thus immersed in the heat transfer fluid contained in the internal degassing volume V.
    Ultimately, the intermediate bend 49, the transfer tube 47 and the plunger tube 51 form a supply line, which connects the transfer port 45 to the dispensing orifice 53. Preferably, the supply line 47 , 49 and 51 comes from material with the cover 7, so that it belongs to the aforementioned upper assembly. The transfer orifice 45, the supply line 47, 49 and 51, as well as the dispensing orifice 53 form means of admission of the coolant to be degassed within the interior degassing volume V. In practice, a part of the coolant admitted into the pipe 19 by the coupling end 25 is taken from the transfer tube 47, so as to be diverted into the supply line 47, 49 and 51 to supply the internal volume of degassing V of the tank 1 heat transfer fluid for the degassing of the latter. This part of the heat transfer fluid thus progresses along the arrow F2 shown in Figure 4 in the supply line 47, 49 and 51 and is discharged into the bottom of the interior degassing volume V.
    A discharge orifice 55 of the coolant out of the internal degassing volume V is formed in the bottom 5. This discharge orifice 55, which is visible both in FIG. 3 and in FIG. 4, is offset relative to to the axis X51 of the plunger tube 51 and is thus not placed opposite the dispensing orifice 53. The discharge orifice 55 is advantageously placed in the lowest part of the bottom 5 to facilitate the evacuation of the coolant contained in the internal degassing volume V with the aid of gravity. Preferably, the orifice 55 is disposed in the bottom 5, between the axis X51 and the axis X29. An evacuation pipe 57 connects the evacuation orifice 55 to the evacuation section 33 of the pipe 19, out of the internal degassing volume V. The evacuation pipe 57 thus extends below the bottom 5 to the bottom. outside the wall 3 and the internal degassing volume V. The pipe 57 forms a bend illustrated in Figures 2 and 4. The coolant is thus removed from the internal degassing volume V along an arrow F3 shown in Figure 4 and reintegrated in the pipe 19 at the elbow 31 and the discharge section 33. The discharge orifice 55 and the discharge pipe 57 form means for discharging the coolant out of the internal degassing volume V, once that this fluid has been degassed. The degassed heat transfer fluid is thus reintegrated into the coolant circuit of the cooling system.
    It will be understood that according to this configuration, the internal section 29 constitutes a means of bypass or "bypass" of a fraction of the heat transfer fluid admitted into the tank 1. The value of this fraction is mainly a function of the ratio between the sections of the tube transfer 47 and the inner section 29.
    Preferably, the inner section 29 is dimensioned so that it occupies as little space as possible within the internal degassing volume V, so that the internal degassing volume V is as large as possible. For this, it is preferred that the inner section 29 is straight, even if other forms can be envisaged.
    The tank 1 finally comprises a partition 59 which protrudes upwards from the bottom 5 by being interposed between the dispensing orifice 53 and the discharge orifice 55. The partition 59 is formed by a central portion 61 and two lateral parts 63, the parts 61 and 63 projecting from the bottom 5 in directions which are parallel to the axis X51. The parts 63 are inclined with respect to the portion 61 so as to form a flat-bottomed V which remotely envelops the plunger tube 51 over at least a majority of its length measured parallel to the axis X51. The partition 59 preferably rises above the nominal level N, or even above the plane defined by the edges 9 and 11. In this case, the central portion 61 is disposed between the plunger tube 51 and the discharge opening 55 being in contact with the plunger tube 51. The lateral parts 63 are in turn curved V around the plunger tube 51 away from the latter. The partition 59 thus forms a curved surface that the heat transfer fluid is forced to bypass in order to flow from the dispensing orifice 53 to the discharge orifice 55. The heat transfer fluid is thus forced to perform baffles according to the arrows. F4 illustrated in Figure 3, which promotes the good outgassing of the heat transfer fluid within the interior degassing volume V.
    In general, the cooling system is designed to cool one or more members of the vehicle. Alternatively, the cooling system cools a thermal engine of the vehicle, the engine being used for example to pull the vehicle.
    The embodiments and variants described in the foregoing may be combined to create new embodiments.
