DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] The controller usually adopts a liquid cooling heat dissipation structure, the heat dissipation structure is connected with the thermal management area of the vehicle controller, the heat dissipation structure is usually provided as a plate shape, a flow channel is arranged in a single layer inside the heat dissipation structure, the flow channel has a liquid inlet and a liquid outlet at two ends respectively, the liquid inlet and the liquid outlet are connected with a cooling liquid driving device, and the flow channel is bent and arranged at the position of the heat dissipation area corresponding to the to-be-cooled part, the cooling liquid enters the flow channel through the liquid inlet, circulates in the flow channel and the heat dissipation area, exchanges heat with the to-be-cooled part, and then flows out through the liquid outlet, so that heat dissipation is realized, which is equivalent to a series heat dissipation structure.

[0035] However, the flow path of the flow channel of the heat dissipation structure with the bent flow channel is relatively long, so that the water resistance in the flow channel is relatively large.

[0036] The large water resistance in the flow channel makes the lift of the cooling liquid driving device longer, the power consumption is relatively large, and the energy consumption is relatively high.

[0037] In order to overcome the defects in the prior art, the heat dissipation structure, the controller and the vehicle provided by the embodiments of the present application arrange the liquid inlet chamber and the liquid outlet chamber along the first direction of the shell, arrange each heat dissipation chamber on one side of the second direction of the liquid inlet chamber and the liquid outlet chamber and along the first direction, and communicate each heat dissipation chamber with the liquid inlet chamber and the liquid outlet chamber, so as to arrange the chambers in different directions, shorten the flow path of the cooling liquid, and reduce the water resistance. And the chamber structure arranged in different directions replaces the bent flow channel structure, the space of each chamber is more sufficient, the liquid flow channel is wider, the liquid flux is larger, the water resistance is smaller, and the heat dissipation structure is still compact. Moreover, after the heat dissipation chamber is connected with the to-be-cooled part, the liquid inlet chamber and the liquid outlet chamber are located on the side of the shell away from the to-be-cooled part, which is more helpful for heat dissipation of the liquid inlet chamber and the liquid outlet chamber, improves the circulating heat exchange effect of the heat dissipation chamber and the thermal management area, so as to improve the heat dissipation efficiency of the heat dissipation structure.

[0038] The content of the utility model will be described in detail in combination with the drawings below, so that the person skilled in the art can understand the content of the utility model more clearly and in detail.

[0039] Reference Figures 1 to 3As shown, the embodiment of the present application provides a heat dissipation structure, comprising: a shell 100, the shell 100 having a liquid inlet chamber 110, a liquid outlet chamber 120 and at least two heat dissipation chambers 130, the heat dissipation chambers 130 being respectively used for connecting with different heat dissipation regions of a to-be-cooled part;

[0040] The liquid inlet chamber 110 and the liquid outlet chamber 120 are arranged in a spaced manner along a first direction;

[0041] Each heat dissipation chamber 130 is located on one side of the liquid inlet chamber 110 and the liquid outlet chamber 120 along a second direction, and the heat dissipation chambers 130 are arranged in a spaced manner, each heat dissipation chamber 130 having a liquid inlet part 131 and a liquid outlet part 132, the liquid inlet part 131 being in communication with the liquid inlet chamber 110, and the liquid outlet part 132 being in communication with the liquid outlet chamber 120, so that the cooling liquid flows into the corresponding heat dissipation chamber 130 through the liquid inlet chamber 110 and the liquid inlet part 131 in sequence, and flows out through the liquid outlet part 132 and the liquid outlet chamber 120 in sequence.

[0042] First of all, it needs to be pointed out that, Figures 1 to 3 The X, Y and Z directions are perpendicular to each other in a three-dimensional space.

[0043] It can be understood that the heat dissipation structure is mainly used for dissipating heat of a to-be-cooled part such as a controller, and the corresponding heat dissipation region may, for example, be a region where a component of the controller such as a power module has obvious heat generation during operation. The shell 100 of the heat dissipation structure is used for connecting with the to-be-cooled part, and the shape of the shell 100 depends on the structure of the to-be-cooled part and needs to be adapted to the to-be-cooled part, which is not limited by the present application.

[0044] For example, when the to-be-cooled part is a controller, the controller can be a double-motor controller adopting a high-density package power module (HPD), or can be a double-motor controller adopting other forms of packaged power modules, or even a single-motor controller, which is not limited by the present application. The heat dissipation structure, the controller and the vehicle provided by the embodiment of the present application will be described below by taking the double-motor controller adopting the HPD form of packaged power module as an example.

[0045] The liquid inlet chamber 110, the liquid outlet chamber 120 and the at least two heat dissipation chambers 130 are arranged on the shell 100, in this embodiment, two heat dissipation chambers 130 are arranged, which are a first heat dissipation chamber 130a and a second heat dissipation chamber 130b. The liquid inlet chamber 110 and the liquid outlet chamber 120 are arranged on the same side of the shell 100 in the thickness direction (second direction) of the shell 100, and along the first direction (X direction) of the shell 100. Figure 3 The Z direction is perpendicular to the X and Y directions. Figure 1 The first heat dissipation chamber 130a and the second heat dissipation chamber 130b are arranged in a spaced manner along the X direction of the shell 100. Figure 2The liquid inlet chamber 110 is connected to the liquid outlet end of the coolant driving device, the liquid outlet chamber 120 is connected to the liquid inlet end of the coolant driving device, and the first heat dissipation chamber 130a and the second heat dissipation chamber 130b are arranged at the other side of the thickness direction (the second direction, i.e. Figure 3 the Z direction) of the shell 100 and are arranged at intervals along the first direction (the X direction). Figure 1 Figure 2 The liquid inlet part 131 of the first heat dissipation chamber 130a and the liquid inlet part 131 of the second heat dissipation chamber 130b are both communicated with the liquid inlet chamber 110, and the liquid outlet part 132 of the first heat dissipation chamber 130a and the liquid outlet part 132 of the second heat dissipation chamber 130b are both communicated with the liquid outlet chamber 120.

[0046] When the coolant driving device is running, the coolant enters the liquid inlet chamber 110 and is divided into two paths in the liquid inlet chamber 110, one path enters the first heat dissipation chamber 130a through the liquid inlet part 131 of the first heat dissipation chamber 130a, and the other path enters the second heat dissipation chamber 130b through the liquid inlet part 131 of the second heat dissipation chamber 130b, and then respectively flows into the liquid outlet chamber 120 through the liquid outlet part 132 of the first heat dissipation chamber 130a and the liquid outlet part 132 of the second heat dissipation chamber 130b, and then flows to the coolant driving device from the liquid outlet chamber 120, which is equivalent to forming a parallel heat dissipation structure.

[0047] In other embodiments, three or more heat dissipation chambers 130 can also be arranged at intervals, which is not limited in the present application.

[0048] The heat dissipation structure provided by the embodiments of the present application arranges the liquid inlet chamber 110 and the liquid outlet chamber 120 along the first direction of the shell 100, arranges each heat dissipation chamber 130 on one side of the second direction of the liquid inlet chamber 110 and the liquid outlet chamber 120, and arranges each heat dissipation chamber 130 along the first direction, so that each heat dissipation chamber 130 is communicated with the liquid inlet chamber 110 and the liquid outlet chamber 120, so as to arrange the chambers in different directions, shorten the flow path of the coolant, reduce the water resistance, and form a parallel heat dissipation structure. Moreover, the chamber structure arranged in different directions replaces the bending and winding serial flow channel structure, the space for arranging each chamber is more sufficient, the liquid flow channel is wider, the liquid flux is larger, the water resistance is smaller, and the heat dissipation structure is still compact.

[0049] Moreover, after the heat dissipation chamber 130 is connected to the heat dissipation object, the liquid inlet chamber 110 and the liquid outlet chamber 120 are located on the side of the shell 100 away from the heat dissipation object, which is more conducive to heat dissipation of the liquid inlet chamber 110 and the liquid outlet chamber 120, improves the circulating heat exchange effect of the heat dissipation chamber 130 and the heat management area, and improves the heat dissipation efficiency of the heat dissipation structure. ​

[0050] In practice, referring to Figures 1 to 3 As shown in the drawings, the heat dissipation chamber 130 is a groove opened on the shell 100.

[0051] It can be understood that the shell 100 is a plate structure with a large Z-direction size, and the plate structure is surrounded by the inner wall of the shell, the cover plate and the like to form the liquid inlet chamber 110 and the liquid outlet chamber 120 on one side along the Z-direction, and a groove is opened on the bottom of the plate to form the heat dissipation chamber 130. The heat dissipation chamber 130 is arranged as a groove structure, so that the heat dissipation fins or heat dissipation needles of the heat dissipation component can be inserted into the heat dissipation chamber 130 through the slot of the groove to exchange heat with the cooling liquid in the heat dissipation chamber 130, and the heat dissipation component can be used to cover the heat dissipation chamber 130 to prevent the cooling liquid in the heat dissipation chamber 130 from leaking.

[0052] Or in some embodiments, a separate cover plate component can also be used to cover the heat dissipation chamber 130, so that the heat dissipation chamber 130 is connected to the heat dissipation component through the cover plate component, and heat conduction fins or heat conduction needles are arranged in the heat dissipation chamber 130. The present application does not limit this.

[0053] In addition, in some embodiments, the liquid inlet chamber 110 and the liquid outlet chamber 120 are usually arranged as an open structure on the side of the shell 100 away from the heat dissipation chamber 130, and a separate cover plate component is needed to cover the liquid inlet chamber 110 and the liquid outlet chamber 120 to seal the liquid inlet chamber 110 and the liquid outlet chamber 120.

[0054] Further, referring to Figures 1 to 3 As shown in the drawings, at least two first through holes and at least two second through holes are respectively arranged on the shell 100, the first through holes and the second through holes are located in the groove, the first through holes correspond to the communication between the groove and the liquid inlet chamber 110, and the second through holes correspond to the communication between the groove and the liquid outlet chamber 120.

[0055] The first through holes form the liquid inlet part 131, and the second through holes form the liquid outlet part 132.

[0056] It can be understood that by opening the first through holes on the groove to form the liquid inlet part 131 and opening the second through holes to form the liquid outlet part 132, the structure of the liquid inlet part 131 and the liquid outlet part 132 is relatively simple and compact, without the need for other communication components, and the heat dissipation structure is easy to process.

[0057] In some embodiments, referring to Figure 1 and Figure 2 As shown in the drawings, the liquid inlet part 131 and the liquid outlet part 132 are respectively adjacent to the two sides opposite to the groove.

[0058] It can be understood that in this way, the liquid inlet part 131 and the liquid outlet part 132 are adjacent to the opposite sides of the groove Y direction, the size of the liquid inlet part 131 and the liquid outlet part 132 can be increased, the area of the liquid inlet part 131 and the liquid outlet part 132 is increased, the liquid flux of the liquid inlet part 131 and the liquid outlet part 132 is improved, and the water resistance is reduced.

[0059] The liquid inlet part 131 and the liquid outlet part 132 can also be adjacent to the opposite sides of the groove X direction, so that the liquid inlet part 131 and the liquid outlet part 132 are spaced apart, and the cooling liquid can more fully fill the heat dissipation chamber 130, and the heat dissipation efficiency of the heat dissipation chamber 130 and the heat dissipation part is improved.

[0060] For example, in the embodiment, the liquid inlet part 131 and the liquid outlet part 132 are respectively located at the two ends of the first heat dissipation chamber 130a and the second heat dissipation chamber 130b along the X direction of the shell 100, and similarly, the liquid inlet part 131 and the liquid outlet part 132 extend to the second heat dissipation chamber 130b and the second heat dissipation chamber 130b along the Y direction of the shell 100. In this way, each liquid inlet part 131 and liquid outlet part 132 is not only connected to the opposite sides of the heat dissipation chamber 130, but also connected to the end of the heat dissipation chamber 130, so that the cooling liquid can more fully exchange heat with the heat dissipation part in the heat dissipation chamber 130.

[0061] In some embodiments, referring to Figure 1 and Figure 3 It is shown that the shell 100 has a partition 101, and the partition 101 divides the shell 100 to form a liquid inlet chamber 110 and a liquid outlet chamber 120.

[0062] It can be understood that by arranging the partition 101 in the shell 100, the space in the shell 100 is divided by the partition 101 to form the liquid inlet chamber 110 and the liquid outlet chamber 120, so that the common shape of the liquid inlet chamber 110 and the liquid outlet chamber 120 in the X and Y directions is consistent with the shape of the shell 100 in the X and Y directions, that is, the liquid inlet chamber 110 and the liquid outlet chamber 120 jointly occupy the space of the shell 100 on that side, so that the volume of the liquid inlet chamber 110 and the liquid outlet chamber 120 is increased, and the water resistance is reduced.

[0063] It should be noted that in this way, the structure of the liquid inlet chamber 110 and the liquid outlet chamber 120 is relatively free, and the shape of the liquid inlet chamber 110 and the liquid outlet chamber 120 can be flexibly arranged in the shell 100 by the partition 101, so that the liquid inlet part 131 of each heat dissipation chamber 130 is communicated with the liquid inlet chamber 110, and the liquid outlet part 132 is communicated with the liquid outlet chamber 120, so as to improve the utilization rate of the space of the shell 100 by the liquid inlet chamber 110 and the liquid outlet chamber 120.

[0064] In some embodiments, referring to Figures 1 to 3As shown, the liquid inlet portions 131 and the liquid outlet portions 132 of the heat dissipation chambers 130 are arranged alternately along the first direction (X direction) in sequence.

[0065] Each liquid inlet portion 131 is located on one side of the partition plate 101, and each liquid outlet portion is located on the other side of the partition plate 101.

[0066] In this way, the flow direction of the cooling liquid in the first heat dissipation chamber 130a and the second heat dissipation chamber 130b is consistent with the spacing direction between the first heat dissipation chamber 130a and the second heat dissipation chamber 130b, which facilitates the layout of the heat dissipation chambers 130, the liquid inlet chamber 110 and the liquid outlet chamber 120, and makes the heat dissipation structure more compact. Moreover, the flow direction of the cooling liquid in each heat dissipation chamber 130 can be consistent in a region, so as to reduce the water resistance in the heat dissipation chamber 130 to a certain extent.

[0067] In some embodiments, referring to Figure 1 and Figure 2 As shown, the housing 100 is provided with a liquid inlet pipe 111 and a liquid outlet pipe 121, the liquid inlet pipe 111 is in communication with the liquid inlet chamber 110, and the liquid outlet pipe 121 is in communication with the liquid outlet chamber 120.

[0068] The liquid inlet pipe 111 and the liquid outlet pipe 121 are both used to be connected with the cooling liquid driving device.

[0069] It can be understood that, by arranging the liquid inlet pipe 111 and the liquid outlet pipe 121 to be connected with the cooling liquid driving device, the heat dissipation structure can be directly plugged with the pipeline of the cooling liquid driving device, so that the connection and assembly of the two are more convenient.

[0070] In the embodiments of the present application, the liquid inlet pipe 111 and the liquid outlet pipe 121 are located on the same side of the housing 100.

[0071] In this way, the cooling liquid driving device and the heat dissipation structure can be more compact after being connected.

[0072] For example, the liquid inlet pipe 111 and the liquid outlet pipe 121 are respectively located on opposite sides of the length direction of the housing 100, which is beneficial to the full flow of the cooling liquid, shortens the flow path of the cooling liquid, and reduces the water resistance.

[0073] In some embodiments, the embodiments of the present application also provide a controller, which comprises a controller body and the heat dissipation structure in any of the above embodiments arranged on the controller body.

[0074] The heat dissipation structure has been described in detail in the above embodiments, and will not be described here again.

[0075] The embodiments of the present application also provide a vehicle, which comprises a vehicle body and a controller arranged on the vehicle body.

[0076] The controller and the vehicle provided by the embodiments of the present application are provided with a heat dissipation structure. The heat dissipation structure is provided with a liquid inlet chamber 110, a liquid outlet chamber 120 and at least two heat dissipation chambers 130 on the shell 100. The liquid inlet chamber 110 and the liquid outlet chamber 120 are arranged along a first direction of the shell 100. Each heat dissipation chamber 130 is located on one side of the liquid inlet chamber 110 and the liquid outlet chamber 120 along a second direction and is arranged along the first direction. Each heat dissipation chamber 130 is in communication with the liquid inlet chamber 110 and the liquid outlet chamber 120. In this way, the chambers are arranged in different directions, the flow path of the cooling liquid is shortened, and the water resistance is reduced. In addition, the chamber structure arranged in different directions is used to replace the flow channel structure arranged in a bending mode. The arrangement space of each chamber is more sufficient, the flow channel of the liquid is wider, the liquid flux is larger, the water resistance is smaller, and the heat dissipation structure is still compact.

[0077] In addition, after the heat dissipation chamber 130 is connected with the heat dissipation object, the liquid inlet chamber 110 and the liquid outlet chamber 120 are located on the side of the shell 100 away from the heat dissipation object, which is more conducive to heat dissipation of the liquid inlet chamber 110 and the liquid outlet chamber 120 and improves the circulation and heat exchange effect of the heat dissipation chamber 130 and the heat management area, so that the heat dissipation efficiency of the heat dissipation structure is improved.
