    DESCRIPTION
    Object of the Invention The present invention relates to a vehicle radiator applicable to the cooling of internal combustion engines, although the radiator of the invention is also applicable to any heat exchanger that works with water or any other liquid fluid that exists. than heat. The radiator of the invention comprises
    10 improvements that provide a more mechanically resistant structure and also a strategic location of some inlets and outlets of the liquid fluid circulating inside the radiator. Technical problem to solve and background of the invention
    15 It is currently customary to use radiators, where the inlet and outlet of the fluid are located in distant areas on opposite sides of the radiator itself, usually because its own operation so encourages it, taking into account that the fluid to be cooled flows from side to side of the radiator, through ducts integrated in a honeycomb of cooling fins.
    20 This described morphology of radiators is called a single step or in "I".
    On the other hand, sometimes the design or size of the vehicle's engine makes it very difficult for the fluid inlet and outlet to be located in opposite areas, sometimes forcing
    25 use complementary connections or sleeves located outside the radiator that complicate the design of the circuit because such sleeves increase the chances of leaks and also because the sleeves are susceptible to deterioration due to the heat they receive due to the proximity to the exhaust manifolds they reach high temperatures
    30 Radiators are also known with the two inlets and outlets of the liquid fluid located on the same side of the radiator, with the disadvantage that in these cases, added outer tubes or ducts are used or of different configuration for the return of the fluid from back and forth and therefore do not adequately resolve the difficulties mentioned above.

    image2
    Radiators with a U-circuit are also known, in which the inlet and outlet mouths are located in the same tank, but have the disadvantage that the coolant is forced to pass twice through the middle of the honeycomb ducts , so that the speed of the liquid through the ducts doubles,
    5 increasing its pressure drop through the honeycomb of the order of four times one way and as many times on its return to the food tank.
    Patent with publication number WO 2016030097 refers to a collection box for an evaporator of an air conditioning circuit that is supplied with the tubes
    10 oriented in a main direction. The box comprises a cover and a distribution plate. It is characterized in that the cover and the distribution plate have a thickness of material that is greater than, or equal to 1 mm., And both elements comprise a portion of the inlet and outlet tubes.
    The patent with publication number EP 0219419 refers to a water box and expansion vessel for a heat exchanger that projects as a monobloc in one piece. The water box includes two reservoirs, while said water box is in a generally vertical position in the heat exchanger, while the expansion chamber extends horizontally above the water box and the
    20 group of ducts in the heat exchanger. In this patent there is a return tube
    or passing between the two tanks, but its section is the same as the rest of the honeycomb ducts, less than 10% of the section of the inlet or outlet mouths, and its function is not to carry all the flow of liquid refrigerant from one tank to the other, but to force a small circulation of liquid through the expansion vessel to favor
    25 the separation of existing gases in the coolant and their containment in the expansion vessel.
    The patent with publication number US 6302196 refers to a heat exchanger comprising flat tubes, each of which has a partition to divide it.
    30 in two parallel ducts; and a plurality of zigzag fins, each of which is disposed between a pair of flat tubes.

    Description of an embodiment of the invention Considering the numbering adopted in the figures, the vehicle radiator comprises a honeycomb structure 1 that includes a multitude of fins 8 in combination with a multitude of ducts 2 having first communicating ends with first deposit 3, and a few extreme seconds that communicate with a
    30 second deposit 4; where the two tanks: first 3 and second 4, are located on opposite sides of the radiator and where the two tanks: first 3 and second 4, also communicate with each other through ends of a tube 5, preferably manufactured with an aluminum material , without discarding other materials; where during the operation of the radiator a liquid fluid circulates through the ducts 2 and tube
    35 5, the liquid fluid passing from the first reservoir 3 to the second reservoir 4, or vice versa.
    image6
    The first tank 3 comprises a larger chamber 3a having a first mouth 6 which communicates with the interior space of said larger chamber 3a and a smaller chamber 3b having a second mouth 7 communicating with the interior space of said smaller chamber 3b; where the major chamber 3a and the minor chamber 3b of the first reservoir 3 are
    5 separated by a first intermediate wall 3c.
    In Figures 6a, 7a and 8a, the second mouth 7 constitutes an inlet of liquid fluid into the smaller chamber 3b of the first reservoir 3, while the first mouth 6 that connects with the interior of the larger chamber 3a constitutes the outlet of liquid fluid to
    10 out of the radiator. In these embodiments, the liquid fluid circulates from the minor chamber 3b of the first reservoir 3 to the second reservoir 4 through the tube 5, and then the liquid fluid circulates from the second reservoir 4 to the major chamber 3a of the first reservoir 3 through of the ducts 2.
    In Figures 6b, 7b and 8b, the first mouth 6 of the major chamber 3a constitutes an inlet of the liquid fluid into the greater chamber 3a of the first reservoir 3, while the second mouth 7 of the smaller chamber 3b constitutes a liquid fluid outlet out of the radiator. In these embodiments the liquid fluid circulates from the greater chamber 3a of the first reservoir 3 to the second reservoir 4 through the ducts 2,
    20 and then the liquid fluid circulates from the second tank 4 to the smaller chamber 3b of the first tank 3 through the tube 5.
    In Figures 1, 2, 3, 4a, 4b, 6a, 6b, the first tank 3 and the second tank 4 are located in vertical positions; highlighting that in figures 1 to 3, 4a and 4b, said
    25 tanks: first 3 and second 4, are located in vertical positions with a convergent downward tilt.
    In contrast, in Figures 7a, 7b, 8a and 8b, the first tank 3 and the second tank 4 can be located in an upper part or in a lower part. Specifically in
    Figures 7a and 7b the first tank 3 is located at the bottom and the second tank 4 is located at the top; while in figures 8a and 8b the first tank 3 is located at the top and the second tank 4 is located at the bottom.
    However, in other complementary embodiments with respect to that shown in Figures 7a and 7b the first tank 3 could be located at the top and the second 4 at the bottom. Following this same criterion, in other complementary embodiments with respect to that shown in Figures 8a and 8b, the first tank 3 could be located at the bottom and the second tank 4 could be located in the
    image7
    5 top.
    The union of the two tanks: first 3 and second 4, by means of the tube 5 constitutes a robust tubular reinforcement that surrounds the honeycomb structure 1; highlighting that in one embodiment the section of said tube 5 is quadrangular in shape as shown in
    10 Figure 5.
    In accordance with the embodiments shown in all the figures, it is emphasized that both the first mouth 6 and the second mouth 7 are located in the same first tank 3 and it also stands out that both mouths: first 6 and second 7, are
    15 next to each other and adjacent to the first intermediate wall 3c separating the major chamber 3a and minor chamber 3b from said first reservoir 3; all this due to space needs and due to the connection with the rest of the components of the cooling circuit of a vehicle engine to be cooled with the radiator of the invention.
    In another embodiment of the invention, the second mouth (7) is located in an area adjacent to the first intermediate wall (3c) that separates the major chamber (3a) and minor chamber (3b) from the first reservoir (3), and The first mouth (6) is located in a central area of the main chamber (3a) of the first tank (3) as shown for example in Figure 7a.
    25 It is also possible that the second mouth (7) is located in an area adjacent to the first intermediate wall (3c) that separates the major chamber (3a) and minor chamber (3b) from the first reservoir (3), and the first mouth (6) is located in an extreme area of the main chamber (3a) away from the first intermediate wall (3c) as
    30 shown in figure 8a.
    On the other hand, it should be noted that the first mouth (6) can be located in any area of the main chamber (3a) of the first tank (3), apart from the areas described in the three preceding paragraphs.
    35 The fact that the two mouths: first 6 and second 7, can be placed with advantage over the same first tank 3, should be highlighted if the space available in the cabin where the radiator is installed advises. Therefore it is noted that with the structure presented by the radiator of the invention, the space necessary to locate the location of connecting ducts between the engine and the radiator is reduced and optimized.
    image8
    5 According to the embodiments shown in all the figures, with tube 5, one of the mouths can be carried: first 6 or second 7, which should be located in the second tank 4, to the first tank 3; all this as if it were a sleeve connected at one end to the second tank 4 and that said sleeve ended at its opposite end in the first tank 3.
    10 The tube 5 is located in a strategic position of the honeycomb structure 1, said armature tube 5 performing the function of the honeycomb structure 1 itself and it is also noted that said tube 5 enhances the stiffness of the corresponding part of the radiator of the invention.
    15 The tube 5 inside comprises internal partitions 10 which together with the surrounding wall of the tube 5 delimit several independent pipes 11 to channel the liquid fluid in a sectorized and independent way, while said internal partitions 10 reduce the induced stresses by the internal fluid pressure
    20 liquid; and said internal partitions 10 provide the radiator with an increase in mechanical resistance against deformations; mainly when the radiator has an arched configuration like the one shown in the plan view of Figure 4a. In another embodiment such as that shown in Figure 4b, the radiator has a straight configuration.
    In another embodiment of the invention, the tube 5 comprises a single passage duct without the inclusion of the internal partitions 10.
    When the radiator assembly is bent in a manufacturing process of the radiator
    30 to obtain the arched structure shown in Figure 4a, during this manufacturing process the tube 5 is also bent preventing it from collapsing and unduly deforming; and it also prevents narrowing its internal section of liquid fluid passage; all this thanks to the internal partitions 10 that said tube 5 includes.
    In one embodiment of the invention, the radiator includes an intermediate plate 9 of


    aluminum located between honeycomb structure 1 and tube 5; wherein said intermediate plate 9 constitutes a connecting piece between said elements: the honeycomb structure 1 and the tube
    5.
    5 For this, the intermediate plate 9 includes on its outer surface a contribution of welding material, so that when the radiator is subjected to the welding process, said intermediate plate 9 unifies and supports the whole of the honeycomb structure 1 and tube 5.
    In another embodiment of the invention, intermediate plate 9 is dispensed with; so that
    10 in this case the contribution of welding material is included in the honeycomb structure 1 achieving a good bond, although the mechanical strength would be lower than with the inclusion of the intermediate plate 9.
    Normally the tube 5 is obtained by an extruded manufacturing process, which is a technique that prevents the application of welding material 5 to said tube.
    The tube 5 comprises a passage section delimited between 20% and 200% with respect to the passage section of the first mouth 6 and second mouth 7 of the radiator.
