[0007] In an optional embodiment, the end cover is provided with a water collecting groove, and the heat conducting plate is mounted on the end cover and seals the notch of the water collecting groove, so that the water chamber is formed in the area where the water collecting groove is located.

[0008] Based on the above scheme, a water chamber is formed by sealing the notch of the water collecting tank with the heat conducting plate, and the heat exchange medium is stored in the water collecting tank, which can simplify the structure of the heat conducting plate and facilitate the processing, manufacturing and installation of the heat conducting plate.

[0009] In an optional embodiment, the end cover includes a main body and a partition, the water collecting trough is provided on the main body, the partition is installed on the main body and is located in the water collecting trough, and is used to divide the water collecting trough into at least two connected sub-troughs, and the heat conducting plate and the shell are both connected to the main body.

[0010] Based on the above scheme, after the heat exchange medium enters the water chamber, the heat exchange medium passes through multiple sub-grooves in sequence during the process of flowing from the water chamber to the outlet, which increases the flow path of the heat exchange medium and extends the flow time of the heat exchange medium in the water chamber. The heat exchange efficiency between the heat exchange medium and the heating unit is high, reducing energy consumption.

[0041] In the prior art, the compressor assembly 100 and the heating assembly 300 are independently arranged, each is equipped with an electric control panel, and are installed separately, which occupies a large space and is not conducive to the miniaturization and lightweight design of the entire vehicle.

[0042] In view of this, the designer provides a vehicle thermal management device with small size and light weight, which is conducive to the miniaturization and lightweight design of the vehicle.

[0043] Please combine Figure 1-Figure 5 In this embodiment, the vehicle thermal management device includes a compressor assembly 100, a circuit board 200 and a heating assembly 300. The heating assembly 300 includes a heating unit 310, a heat conducting plate 320 and an end cover 330. The heating unit 310 is mounted on the heat conducting plate 320. The heat conducting plate 320 is connected to the end cover 330 and the two cooperate to define a water chamber for storing a heat exchange medium. The end cover 330 is connected to the housing 110 of the compressor assembly 100. The end cover 330 cooperates with the housing 110 to define a device cavity. The circuit board 200 is located in the device cavity. The compressor assembly 100 and the heating assembly 300 are both connected to the circuit board 200 for communication.

[0044] Based on the above, the vehicle thermal management device provided in this embodiment integrates the compressor assembly 100 and the heating assembly 300 together, so that the overall structure is compact, the volume is small, and the space occupied is small. At the same time, the compressor assembly 100 and the heating assembly 300 are both connected to the circuit board 200 for communication, and the compressor assembly 100 and the heating assembly 300 can be controlled by using a circuit board 200. Compared with the solution of the prior art that the compressor assembly 100 and the heating assembly 300 each independently use a circuit board 200, one circuit board 200 is reduced, and the overall weight is reduced. In addition, the heat conducting plate 320 and the end cover 330 cooperate to form a water chamber for storing the heat exchange medium, that is, the heat conducting plate 320 is not only a component for exchanging heat with the heat exchange medium, but also a component for forming the water chamber. Compared with the prior art, the water chamber structure is simplified, parts are saved, the overall volume is further reduced, and the overall weight is reduced, which is conducive to the miniaturization and lightweight design of the vehicle.

[0045] The following embodiments illustrate the details of the vehicle thermal management device of the present application by way of examples.

[0046] Please combine Figure 1-Figure 3 In this embodiment, optionally, the compressor assembly 100 includes a housing 110, and the interior of the housing 110 is used to assemble components such as a motor, a fixed scroll, and a movable scroll. One end of the housing 110 is set to be open, and the open end of the housing 110 is used to connect with the end cover 330 of the heating assembly 300. For example, the end of the housing 110 with an open end is provided with a plurality of first mounting lugs 120, and the plurality of first mounting lugs 120 are arranged at intervals in the circumferential direction of the housing 110. For example, in this embodiment, the number of the first mounting lugs 120 is eight. Obviously, in other embodiments, the number of the first mounting lugs 120 is not limited to eight.

[0047] Please combine Figure 2 and Figure 4 In this embodiment, optionally, the heating assembly 300 includes a heating unit 310, a heat conducting plate 320 and an end cover 330. The heating unit 310 can be an mch heating structure or a thick film heating structure. The heating unit 310 is installed on the heat conducting plate 320. The heating unit 310 can conduct heat to the heat conducting plate 320, and then transfer the heat to the heat exchange medium through the heat conducting plate 320. The heat exchange medium flows in the pipeline and takes away the heat. The heat conducting plate 320 is connected to the end cover 330, and the two cooperate to define a water chamber. The end cover 330 is connected to the shell 110, and the two define an equipment cavity independent of the water chamber.

[0048] Optionally, when the heating unit 310 is set as an mch heating structure, the heating unit 310 includes a ceramic body and a heating wire sintered inside the ceramic body, and the heating wire can extend in a curved structure such as a spiral or a meandering shape, which can increase the coverage area and improve the heating efficiency. In addition, a metal layer can be sintered on the outer surface of the ceramic body, and the heating unit 310 can be welded to the heat conducting plate 320 using the metal layer. Alternatively, in other embodiments, the heating unit 310 can be directly bonded to the heat conducting plate 320.

[0049] Optionally, when the heating unit 310 is configured as a thick film heating structure, the thick film heating structure is directly attached to the heat conducting plate 320 , and the thick film heating structure and the heat conducting plate 320 can be fixed by welding or bonding.

[0050] In addition, the heating assembly 300 may further include fins, and the fins may be fixed on the heat conducting plate 320 , or the fins may be fixed on the heating unit 310 , etc.

[0051] Furthermore, the heat conducting plate 320 has a first plate surface and a second plate surface relative to each other. When the heat conducting plate 320 is installed on the end cover 330, the first plate surface is located on the side of the second plate surface close to the end cover 330, and the heating unit 310 is installed on the second plate surface. In this way, the heating unit 310 is located outside the water chamber, and the heating unit 310 is not directly in contact with the heat exchange medium, which can reduce the requirements for the waterproof performance of the heating unit 310 and reduce the preparation cost of the heating unit 310; at the same time, the heating unit 310 is not immersed in the heat exchange medium for a long time, the risk of being damaged is small, and the service life is long. It should be understood that in other embodiments, the heating unit 310 can also be arranged in the water chamber, directly in contact with the heat exchange medium, to reduce heat loss.

[0052] Please combine Figure 2 and Figure 5 Optionally, the end cover 330 includes a body 331 and a partition 332. The body 331 is a rectangular structure. A groove 333 is provided on the body 331. An annular positioning groove 334 and a plurality of second mounting lugs 335 are provided on the end surface where the groove 333 is located. The plurality of second mounting lugs 335 are arranged at intervals in the circumferential direction of the end cover 330. For example, in this embodiment, the number of the second mounting lugs 335 is eight, which is consistent with the number of the first mounting lugs 120. The groove 333 has a first side wall and a second side wall opposite to each other. A slope 336 is provided on the groove bottom wall of the groove 333. A water inlet 337 and a water outlet 338 are provided on the first side wall. The water inlet 337 and the water outlet 338 are both located on the lower side of the slope 336. The partition 332 is installed in the groove 333. The bottom side of the partition 332 fits the groove bottom wall. One side of the partition 332 abuts against the first side wall, and the other side is spaced from the second side wall. The partition 332 separates the water inlet 337 and the water outlet 338, and divides the groove 333 into two sub-grooves. The heat exchange medium entering the water inlet 337 needs to bypass the partition 332 before it can leave the water outlet 338. In addition, the slope 336 slows down the flow speed of the heat exchange medium, prolongs the time the heat exchange medium stays in the water chamber, and improves the heat exchange efficiency. The heat conducting plate 320 is embedded in the annular positioning groove 334 , and the heat conducting plate 320 can be fixedly connected to the end cover 330 by bolts or other structures. In order to improve the sealing performance, a sealing ring can be provided between the heat conducting plate 320 and the bottom wall of the annular sealing groove 333 .

[0053] During assembly, the multiple first mounting lugs 120 on the housing 110 correspond to the multiple second mounting lugs 335 on the end cover 330 one by one, and fasteners such as bolts are passed through the second mounting lugs 335 and then screwed and fixed to the first mounting lugs 120 .

[0054] Alternatively, in other embodiments, the heat conducting plate 320 can be clamped between the shell 110 and the end cover 330. For example, a through hole is set on the heat conducting plate 320, and the fastener can pass through the through hole. After the fastener fixes the shell 110 and the end cover 330, the shell 110 and the end cover 330 are used to clamp the heat conducting plate 320, so that the assembly of the shell 110, the heat conducting plate 320 and the end cover 330 is convenient.

[0055] The vehicle thermal management device provided in this embodiment has a compact structure, small size, light weight, and is easy to install.

[0056] This embodiment also provides an electric vehicle, including the above-mentioned vehicle thermal management device, which can achieve lightweight and miniaturized design.

[0057] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
