    专利说明:

    The invention relates to an engine device which comprises an oil sump and a heat exchanger.
    In the automotive sector, it is known to use a water-oil heat exchanger to regulate the temperature of the engine oil.
    Thus, the water-oil heat exchanger can accelerate the rise in temperature of the engine oil and can also allow to cool the engine oil.
    Indeed, when starting a motor vehicle, the water in the cooling circuit heats very quickly, while the engine oil experiencing a rise in temperature slower. However, the engine can not operate fully until the oil has reached the correct temperature.
    To accelerate the heating of the oil, it is known to use a water-oil heat exchanger. The heat exchanger most often has a stack of water and oil circuits in close contacts to allow heat transfer from the water to the oil.
    Following recent developments, the oil sump can be made of plastic, while the heat exchangers are made of aluminum. Aluminum has the advantage of being coolant and thus facilitate heat exchange between water and oil.
    However, the assembly of the aluminum heat exchanger on the plastic oil sump involves the use of gaskets and requires fasteners by bolting, which increases: the number of manufacturing operations, the assemblies and therefore the cost.
    Accordingly, it is an object of the present invention to provide an engine device that can be assembled with a reduced number of manufacturing operations.
    According to a general definition, the invention relates to an engine device which comprises a plastic oil sump having a hollow shape containing lubricating oil delimited by a bottom wall, a plurality of side walls and upper flanges. The oil sump has at least one exchanger surface which comprises oil circulation means and means for circulating a cooling liquid, and a heat exchanger in which oil and a cooling liquid circulate. , comprising a series of plastic plates welded in pairs and welded to the exchanger surface.
    Thus, the invention provides an engine device which comprises an oil sump and a heat exchanger made of plastic. The assembly of the heat exchanger on the oil sump is made by welding and eliminates a seal. The invention therefore proposes an engine device which can be assembled with a reduced number of manufacturing operations.
    In addition, the presence of an exchanger surface on the oil sump makes it possible to maximize the tightness of the connection between the oil sump and the heat exchanger.
    The exchanger surface may be molded with the oil sump.
    This technical arrangement makes it possible to reduce the number of manufacturing operations of the device.
    According to another embodiment, the exchanger surface may be positioned on one of the side walls of the oil sump.
    According to one embodiment, the exchanger surface can be positioned on one of the upper flanges of the oil sump.
    The plates of the heat exchanger may be made of polyamide comprising between 30% and 60% of an additive belonging to the group comprising graphite and carbon. Advantageously, the addition of graphite or carbon in the polyamide makes it possible to increase the heat transfer capacity of the heat exchanger.
    The oil sump can be made of polyamide.
    A first exchange zone of each plate may have a plurality of projections configured to cooperate with fingerprints of a second corresponding exchange zone of a contiguous plate.
    The series of plates of the heat exchanger may comprise oil flow plates having oil flow means on the first exchange zone of the oil flow plate, and oil flow plates. coolant flow having coolant flow means on the first exchange zone of the coolant flow plate.
    The exchanger surface may be surrounded by an assembly rib.
    Each plate of the heat exchanger can be surrounded by an assembly rib.
    The joining ribs of the exchange surface and each plate of the heat exchanger can be configured to be soldered in pairs. The heat exchanger may comprise a closure plate welded to the series of plates of the heat exchanger.
    The plates of the heat exchanger can be welded by electromagnetic induction.
    The series of plates of the heat exchanger can be welded to the exchanger surface by electromagnetic induction.
    According to a particular arrangement, at least one of the plates may have a thickness different from the thickness of the other plates of the heat exchanger.
    The oil sump may include at least one receptacle configured to receive an oil filter.
    At least one side wall of the oil sump may have an opening near the bottom wall, the opening being configured to receive a drain plug. Other features and advantages of the invention will become apparent from the description which follows, with reference to the accompanying drawings which show two embodiments of the invention.

    Figure 2 is an exploded perspective view of the invention according to a second embodiment;
    FIG. 3 is an exploded perspective view of a series of plates of a heat exchanger according to a second embodiment of the invention;
    With reference to FIGS. 1 and 2, the invention relates to a device 1 for an engine which comprises an oil sump 2 and a heat exchanger 4.
    The oil sump 2 is made of plastic, according to the examples presented here, the oil sump 2 can be made of molded polyamide.
    The oil sump 2 has a hollow form 21 containing lubricating oil delimited by a bottom wall 22, a plurality of side walls 24, upper flanges 25. In general, the oil sump 2 can have a receptacle 26 configured to receive an oil filter 7.
    In addition, the oil sump 2 has an exchanger surface 30.
    According to the first embodiment, shown in FIG. 1, the heat exchanger surface 30 is positioned on a side wall 24 of the oil sump 2. In a particularly advantageous manner, the heat exchanger surface 30 is molded with the oil sump 2.
    The exchanger surface 30 comprises oil circulation means and means for circulating a cooling liquid.
    The oil circulation means comprise oil circulation holes 34.
    The coolant circulation means comprise coolant circulation orifices 35.
    In addition, the exchanger surface 30 has an array of cavities 31 which makes it possible to distribute the fluid over the entire surface of the exchanger 30, so as to maximize heat exchange.
    The exchanger surface 30 is surrounded by an assembly rib 32 whose function will be detailed later.
    2 to appreciate a second embodiment of the device 1. It is specified that for simplification, the elements that have the same function, in both embodiments, have the same reference.
    According to the second embodiment, the exchanger surface 30 is positioned on an upper rim 25. The heat exchanger 4 is shown in FIGS. 1 to 3. As can be seen, the heat exchanger 4 comprises a series of plates 41.
    Each plate 41 has oil circulation means and means for circulating the cooling liquid.
    The oil circulation means comprise oil circulation holes 48.
    The coolant circulation means comprise coolant circulation holes 49.
    Each plate 41 is surrounded by an assembly rib 42 whose function will be detailed below.
    Each plate 41 has a first exchange zone 43 which has a plurality of projections 44. In addition, each plate 41 has a second exchange zone 45 which has a plurality of cavities 46.
    The projections 44 of each plate 41 are configured to cooperate with the indentations 46 of another adjacent plate 41 or with the indentations 31 of the exchanger surface 30. In a particularly advantageous manner, the protrusions 44 and the indentations 46 present each geometry adapted to optimize heat exchange.

    As can be seen, the series of plates 41 may further comprise a closure plate 41c. The closure plate 41c may have substantially smooth or ribbed faces. The closure plate 41c is positioned at the free end of the series of plates 41. In a particularly advantageous manner, the plates 41 are made of polyamide comprising between 30% and 60% of a load which makes it possible to increase the heat exchange capacity of the plates 41. The load may, for example, comprise graphite or carbon. In use, the connecting ribs 42 of each plate 41 are welded two-by-two. In addition, the connecting rib 42 of the plate 41 adjacent to the heat exchanger surface 30 is welded to the connecting rib 32 of the heat exchanger surface 30.
    According to a particular arrangement, the welds are made by electromagnetic induction.
    As can be seen in the figures, a motor device without a seal is thus obtained because the welding of the polyamide heat exchanger loaded on the polyamide oil sump makes it possible to guarantee the tightness of the device. . In addition, the use of an oil sump and a polyamide heat exchanger makes it possible to shorten the manufacturing process of the engine device.
