Description

Heat abstractor, power device module and vehicle

Technical Field

The present utility model relates to a heat sink, and also relates to a power device module including such a heat sink and a vehicle including such a power device module.

Background

The constituent elements of the power device module may generate heat during operation, and heat accumulation may affect the normal operation of the power device module and even cause damage thereto. Thus, the power device module is typically provided with a heat sink, which typically comprises a heat sink and a housing arranged in one piece, which may form a heat transfer fluid conduit in the same plane for transferring heat from the heat generating elements of the power device module. However, such heat sinks cannot be flexibly constructed and adapted according to the actual needs of the user, because the construction of the entire integrally formed heat sink needs to be modified for different customer needs, e.g. different installation environments, which often involves a lot of modification work. Furthermore, heat transfer fluid lines lying in the same plane do not achieve efficient heat dissipation.

Accordingly, there remains a need for a new heat sink that overcomes at least some of the problems of the prior art, as well as other advantages.

Disclosure of utility model

To this end, the present utility model proposes a heat dissipating device for a power device module, the heat dissipating device comprising:

a housing provided with an inlet conduit for a heat transfer fluid and an outlet conduit, the inlet conduit comprising a fluid inlet and a first docking end, the outlet conduit comprising a fluid outlet and a second docking end;

A radiator detachably mounted in the housing, and provided with a flow-through duct for the heat transfer fluid therein, the flow-through duct including an inlet end and an outlet end;

Wherein the inlet end is arranged to dock with a first docking end of the inlet pipe, and the outlet end is arranged to dock with a second docking end of the outlet pipe; and wherein the flow conduit is at least partially at a different level than the inlet conduit and/or than the outlet conduit.

Thus, in the heat dissipating device proposed by the present utility model, the provision of the heat sink detachably mounted into the housing allows the configuration of the housing for mounting into the user's use environment to be customized according to the needs of the customer in no use, thereby allowing the housing to be adapted to different mounting environments in a flexible manner without having to change the configuration of the heat sink itself. This can greatly simplify design and manufacturing modifications to adapt to different customer needs, thereby improving cost effectiveness. Furthermore, providing the flow conduit in the heat sink at least partially at a different level than the inlet and/or outlet conduits in the housing allows for an extension of the flow path of the heat transfer fluid in the heat sink without having to increase the length or width dimensions of the heat sink, thereby facilitating an overall compact heat sink while improving heat dissipation efficiency.

According to various embodiments, the heat dissipating device according to the present utility model may comprise one or more of the following further developments.

In some embodiments, the docking is in a vertical direction.

In some embodiments, the first docking end and/or the second docking end are open upward in a vertical direction; the inlet end and/or the outlet end opens downwards in a vertical direction.

In some embodiments, the inlet end and/or the outlet end is provided on a respective downwardly extending bend of the flow conduit.

In some embodiments, the first mating end is an elongated opening elongated along a main direction of extension of the inlet conduit, the inlet end is an elongated opening mated with the first mating end, the second mating end is an elongated opening elongated along a main direction of extension of the outlet conduit, and the outlet end is an elongated opening mated with the second mating end. The elongated opening allows the butt joint portion having a relatively large cross section to be realized without increasing the width dimension, thereby ensuring the flow rate of the heat transfer fluid to improve the heat radiation efficiency of the heat radiation device.

In some embodiments, the heat sink further comprises a first seal disposed between the inlet end and the first mating end, and a second seal disposed between the outlet end and the second mating end.

The utility model also relates to a power device module, characterized in that it comprises a heat-generating component and a heat-dissipating device according to the above, which is arranged to dissipate heat originating from the heat-generating component.

According to some embodiments, in the power device module according to the present utility model, the heat generating component includes electronic and/or electric components disposed along both sides of the flow conduit. This allows an efficient transfer of heat emitted by the electronic and/or electrical components.

According to some embodiments, in the power device module proposed by the present utility model, the flow-through duct is provided at a level higher than a fixed structure for mounting the electronic and/or electrical components. This prevents the fixing structure from adversely affecting the strength of the flow conduit.

The utility model also relates to a vehicle comprising a power device module as described above.

Referring to fig. 1-5, the present utility model proposes a heat sink 10 that may be used with a power device module 1. More specifically, the power device module 1 may include electronic and/or electrical components that generate heat during operation, and the heat dissipation device 10 of the present utility model is configured to dissipate heat generated by the electronic and/or electrical components of the power device module 1.

In one embodiment, the heat sink 10 may include a housing 100 and a heat sink 200, and the heat sink 200 may be mounted within the housing 100, more particularly, in a removable manner within the housing 100. The housing 100 may be provided with an inlet pipe 110 and an outlet pipe 120 for the heat transfer fluid, and the inlet pipe 110 and the outlet pipe 120 may be directly cast in the housing 100 or may be formed of a pipe embedded in the housing 100. The inlet conduit 110 may include a fluid inlet 111 and a first mating end 112 for heat transfer fluid to flow into the heat sink 10, and the outlet conduit 120 may include a fluid outlet 121 and a second mating end 122 for heat transfer fluid to flow out of the heat sink 10. In a specific embodiment, the heat sink 10 may further comprise a fluid temperature sensor (not shown) disposed at the fluid inlet 111 of the inlet conduit 110 for sensing the temperature of the heat transfer fluid entering the inlet conduit 110. The heat sink 200 may be provided with a flow conduit 210 for the heat transfer fluid, the flow conduit 210 may comprise an inlet end 212 for the heat transfer fluid to enter the flow conduit 210 and an outlet end 222 for the heat transfer fluid to exit the flow conduit 210, the inlet end 212 being arranged to interface with the first interface end 112 of the inlet conduit 110 in the housing 100 and the outlet end 222 being arranged to interface with the second interface end 122 of the outlet conduit 120 in the housing 100, such that the flow conduit 210 in the heat sink 200 may form a flow path for the heat transfer fluid in the heat sink 10 together with the inlet conduit 110 and the outlet conduit 120 in the housing 100. More specifically, the flow conduit 210 in the radiator 200 may be arranged at least partly at a different level than the inlet conduit 110 and/or the outlet conduit 120 in the housing 100, i.e. offset in the height direction as shown in the figures.

Thus, in the heat sink 10 proposed by the present utility model, the provision of the heat sink 200 detachably mounted into the housing 100 allows the configuration of the housing 100 for mounting into a user's use environment to be customized according to the needs of an unused customer, thereby allowing the housing 100 to be adapted to different mounting environments in a flexible manner without having to change the configuration of the heat sink 200 itself. This can greatly simplify design and manufacturing modifications to adapt to different customer needs, thereby improving cost effectiveness. Furthermore, providing the flow conduit 210 in the heat sink 200 at least partially at a different level than the inlet conduit 110 and/or the outlet conduit 120 in the housing 100 allows for an extension of the flow path of the heat transfer fluid in the heat sink 10 without having to increase the length or width dimensions of the heat sink 10, thereby facilitating an overall compact heat sink 10 while improving heat dissipation efficiency.

In some embodiments, as shown in fig. 2 and 3, the above-described docking is a docking in a vertical direction. More specifically, the interface between the inlet end 212 of the flow conduit 210 in the radiator 200 and the first interface end 112 of the inlet conduit 110 of the housing 100 is in a vertical direction. Furthermore, the interface between the outlet end 222 of the flow conduit 210 in the radiator 200 and the second interface end 122 of the outlet conduit 120 of the housing 100 is also an interface in the vertical direction. It should be noted that in the sense of the present utility model, the vertical direction corresponds to the "opposite" vertical direction shown in the figures, which does not necessarily correspond to the true vertical direction in the actual use of the heat sink 10. More specifically, if the heat sink 10 is installed in an orientation different from that shown in the drawings in an actual use environment, the vertical direction should be understood differently accordingly. More specifically, the inlet end 212 of the flow conduit 210 of the radiator 200 and the first butt end 112 of the inlet conduit 110 of the housing 100 face each other in the vertical direction; additionally, the outlet end 222 of the flow conduit 210 of the heat sink 200 and the second mating end 122 of the outlet conduit 120 of the housing 100 also face each other in a vertical direction. To this end, the first mating end 112 of the inlet duct 110 and/or the second mating end 122 of the outlet duct 120 of the housing 100 are open upward in a vertical direction relative to the orientation shown in the figures, and correspondingly the inlet end 212 and/or the outlet end 222 of the flow duct 210 of the radiator 200 are open downward in a vertical direction.

In one embodiment, as shown in fig. 2, the inlet end 212 and/or the outlet end 222 of the flow conduit 210 of the heat sink 200 are respectively disposed on corresponding downward extending bends 210a (only bends corresponding to the inlet end 212 are shown) of the flow conduit 210. More specifically, the flow conduit 210 of the heat sink 200 may include a horizontally extending portion having a U-shape in a horizontal plane as shown in the drawing, which may include a first leg 210b and a second leg that are substantially parallel to each other and an intermediate connection section connecting the first leg 210b and the second leg. In this case, the inlet end 212 of the flow conduit 210 of the radiator 200 may be provided at a free end of the bent portion 210a extending downward from an end of the first leg 210b remote from the intermediate connection section; additionally, the outlet end 222 of the flow conduit 210 of the heat sink 200 may be provided at a free end of a bend extending downwardly from an end of the second leg remote from the intermediate connection section.

In one embodiment, as shown in fig. 2, the inlet duct 110 and/or the outlet duct 120 of the housing 100 may be arranged to extend mainly in a horizontal direction, for example in a substantially rectilinear form. Alternatively, the inlet duct 110 of the housing 100 may be provided in an L-shape having a horizontally extending section 110b and a vertically extending section 110a bent upward from an inner end of the horizontally extending section 110b, and the first docking end 112 may be provided at a free end of the vertically extending section 110 a. Still alternatively, the outlet duct 120 of the housing 100 may also be arranged to extend mainly in a horizontal direction, for example in a substantially rectilinear form. Alternatively, the outlet conduit 120 of the housing may also be provided in an L-shape having a horizontally extending section and a vertically extending section bent upwardly from the inner end of the horizontally extending section, and the second mating end 122 may be provided at the free end of the vertically extending section.

In some embodiments, as shown in fig. 4 and 5, the first mating end 112 of the inlet duct 110 in the housing 100 is an elongated opening elongated in the main extension direction (horizontal direction in the drawing) of the inlet duct 110, and correspondingly, the inlet end 212 of the flow duct 210 in the radiator 200 is an elongated opening that mates with the first mating end 112 of the inlet duct 110 of the housing 100. More specifically, the heat sink 10 may also be provided with a first seal 300, more specifically an annular seal, between the inlet end 212 of the flow conduit 210 of the heat sink 200 and the first mating end 112 of the inlet conduit 110 of the housing 100. More specifically, a first annular groove 113 for receiving the first annular seal 300 may also be provided in the abutting end face of the first abutting end 112 of the inlet duct 110 of the housing 100. Similarly, the second mating end 122 of the outlet conduit 120 in the housing 100 is an elongated opening elongated along the main extension direction (e.g., horizontal direction) of the outlet conduit 120, and correspondingly, the outlet end 222 of the flow conduit 210 in the heat sink 200 is an elongated opening that mates with the second mating end 122. More specifically, the heat sink 10 may also be provided with a second seal 400, more specifically an annular seal, between the outlet end 222 of the flow conduit 210 of the heat sink 200 and the second mating end 122 of the outlet conduit 120 of the housing 100. More specifically, a second annular groove 123 for receiving the second annular seal 400 may also be provided in the abutting end face of the second abutting end 122 of the outlet conduit 120 of the housing 100. Providing the first and second mating ends 112, 122 as elongated openings allows for a mating portion having a relatively large cross-section to be achieved without increasing the width dimension, thereby ensuring a flow rate of the heat transfer fluid to increase the heat dissipation efficiency of the heat dissipation device 10. The arrangement of the first and second seals 300 and 100 and the manner in which they are arranged ensure a good seal between the heat sink 200 and the housing 100, thereby effectively avoiding leakage of the heat transfer fluid.

It should be noted that the positions of the inlet duct 110 and the outlet duct 120 of the housing 100 shown in the figures are interchangeable.

According to another aspect of the utility model, the utility model also relates to a power device module 1, which power device module 1 comprises a heat generating component 20 and a heat dissipating arrangement 10 according to any of the previous embodiments, the heat dissipating arrangement 10 being arranged to dissipate heat originating from the heat generating component 20. More specifically, as shown in fig. 1, in the power device module 1 according to some embodiments, the heat generating component 20 includes electronic and/or electric components disposed along both sides of the flow passage in the heat sink. This allows an efficient transfer of heat emitted by the electronic and/or electrical components. More specifically, the power device module 1 may further comprise electronic and/or electrical components arranged in the inner space of the flow duct 210 of the heat sink 200, in which case a heat conducting potting compound may be filled between the electronic and/or electrical components in order to conduct the heat emitted by the electronic and/or electrical components to the flow duct 210, allowing the heat to be emitted via the heat transfer fluid within the flow duct 210.

According to some embodiments, as shown in fig. 1, in the proposed power device module 1, the flow duct 210 of the heat sink 200 is provided at a level higher than the fixing structure 30 for mounting electronic and/or electric components. This prevents the fixing structure 30 from adversely affecting the strength of the flow conduit 210. The fixing structure 30 includes, for example, a threaded hole and a screw screwed into the corresponding threaded hole.

According to a further aspect of the utility model, the utility model also relates to a vehicle comprising a power device module 1 as described above. More specifically, the vehicle may be an electrified vehicle (ELECTRIFIED VEHICLE), such as a Battery electric vehicle (BEV, battery ELECTRIC VEHICLE), a Hybrid electric vehicle (HEV, hybrid ELECTRIC VEHICLE), a Plug-in Hybrid ELECTRIC VEHICLE, an extended range electric vehicle (Range extended EV), a Fuel cell vehicle (FCEV, fuel CELL ELECTRIC VEHICLE). The vehicle may also be a hydrogen-powered vehicle.
