[0038] Electric vehicles have made continuous breakthroughs in terms of driving range, charging speed, and safety. However, thermal management remains one of the key technologies that urgently needs to be addressed in the field of electric vehicles.

[0039] As an important component of the thermal management system, the heater is responsible for providing functions such as heating and defrosting inside the vehicle.

[0040] Existing heaters are usually installed independently, which takes up a lot of space and has high operating costs.

[0041] In view of this, the present invention provides a compressor assembly, a thermal management system, and an automobile, which integrates the heater with the electrical control box of the compressor body, greatly increasing the system integration and effectively reducing the space occupied by the heater.

[0042] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0043] like Figure 1 , Figure 2 as well as Figure 4 As shown, this utility model embodiment proposes a compressor assembly, which includes:

[0044] The compressor body 100 has a mounting groove 110 on its surface. It is understood that the mounting groove 110 is integrated into the outer surface of the compressor body 100, and is used to mount the electrical control system of the compressor body 100. The electrical control system can control the operating state of the compressor body 100. The compressor body 100 can adopt a commonly used design structure, and this application embodiment does not limit it.

[0045] A heater 200 is located at one end of the compressor body 100, and the heater 200 and the compressor body 100 cooperate to form an electrical control cavity. It is understood that the surface of the compressor body 100 is provided with a mounting groove 110, that is, the outer surface of the compressor body 100 integrates a mounting groove 110, which is used to install the electrical control system of the compressor body 100. The electrical control system can control the working state of the compressor body 100. The compressor body 100 can adopt a commonly used design structure, and this embodiment is not limited thereto. The heater 200 is located at the opening of the mounting groove 110, and cooperates with the mounting groove 110 to form the electrical control cavity. It is understood that the heater 200 is located at the opening of the mounting groove 110 and is adapted to the outer contour of the opening. The heater 200 can seal the opening of the mounting groove 110, thereby cooperating with the mounting groove 110 to jointly form the electrical control cavity. In other words, the heater 200 replaces the original cover of the compressor's electrical control box. The heater 200 is integrated with the electrical control box of the compressor body 100, eliminating the need for a separate heater 200. The heater 200 is integrated into the existing electrical control box cover space, effectively reducing space occupation and the overall size of the thermal management system. Optionally, the heater 200 is an electric heater. Of course, in other embodiments, the mounting slot 110 can also be integrated into the heater 200, which will not be detailed further.

[0046] A control board 300 is located in the electrical control cavity and is electrically connected to the compressor body 100 and the heater 200. It is understood that the heater 200 is electrically connected to the control board 300 via electrodes or wires, and the compressor body 100 is electrically connected to the control board 300 via wires. A single control board 300 can simultaneously control the operation of both the heater 200 and the compressor body 100, providing greater convenience.

[0047] A heat insulation component 400 is disposed in the electrical control cavity and located between the heater 200 and the control board 300. It is understood that the heat insulation component 400 can isolate the heat from the heater 200, reduce the heat transferred to the control board 300, prevent the control board 300 from overheating and affecting normal operation, thereby reducing the adverse effects of the high temperature of the heater 200 on the control board 300. Specifically, the heat insulation component 400 can be a plate-like structure made of fiberglass, asbestos, rock wool, etc.

[0048] In this embodiment, the heater 200 and the compressor body 100 cooperate to form an electrical control cavity, and the control board 300 is placed in the electrical control cavity. Integrating the heater 200 with the electrical control box of the compressor body 100 significantly increases system integration and effectively reduces the space occupied by the heater 200. Compared to a separate heater 200, the overall size of the thermal management system is reduced, achieving miniaturization, lightweighting, and modularization. Furthermore, the original cover of the electrical control box is eliminated; the heater 200 directly seals the mounting slot 110 of the compressor body 100, reducing the number of components used and making disassembly and assembly more convenient. This not only reduces costs but also further lightens the overall weight. In addition, a heat insulation component 400 is provided between the heater 200 and the control board 300, which reduces the temperature transferred from the heater 200 to the control board 300, preventing the temperature of the control board 300 from rising and ensuring its normal operation.

[0049] In one embodiment of this utility model, reference is made to Figure 3 and Figure 4 The heater 200 includes:

[0050] The heating shell 210 has a heating chamber inside and is equipped with an inlet 260 and an outlet 270 communicating with the heating chamber; and

[0051] Heating film 220 is disposed on heating shell 210.

[0052] Specifically, the heater 200 includes a heating shell 210 and a heating film 220. The heating shell 210 has a heating chamber for heating the incoming coolant. Optionally, the heating shell 210 has an inlet 260 and an outlet 270. The coolant enters the heating chamber through the inlet 260, is heated, and then flows out of the heating chamber through the outlet 270, providing a heat source for the thermal management system and enabling heating of the vehicle's interior. The heating film 220, as a heat source, provides heat to the heating chamber, thereby exchanging heat with the coolant and heating it. In one embodiment, the heating film 220 is disposed on the outer surface of the heating shell 210; however, it can also be disposed on the inner surface of the heating shell 210, without limitation.

[0053] In this embodiment, the heating film 220 is typically lightweight, which reduces the weight of the heater 200, thereby reducing the overall weight of the vehicle and improving the electric vehicle's range. Simultaneously, due to the efficient heating characteristics of the heating film 220, the required heating effect can be achieved with lower energy consumption, contributing to a reduction in the overall energy consumption of the electric vehicle. It is understood that the heating film 220 generates heat when energized, and this heat is conducted to the heating shell 210, thereby heating the coolant. In one embodiment, the heating film 220 can be disposed on the inner surface of the heating shell 210, resulting in less heat loss and higher heating efficiency. Of course, in other embodiments, the heating film 220 is disposed on the outer surface of the heating shell 210, which reduces the difficulty of connecting the heating film 220 to the control board 300.

[0054] In one embodiment of this utility model, reference is made to Figure 3 and Figure 6 The heating shell 210 includes a connected shell 211 and a base plate 212, which together form a heating chamber. An inlet 260 and an outlet 270 are located on the shell 211. At least one of the base plate 212 and the shell 211 is provided with a heating film 220. Specifically, the heating film 220 can be located on the base plate 212, on the shell 211, or simultaneously on both the base plate 212 and the shell 211.

[0055] In one embodiment, the housing 211 and the base plate 212 can be fixed by welding, such as brazing, which can ensure the reliability of the connection between the housing 211 and the base plate 212 and prevent leakage.

[0056] In other embodiments, the housing 211 and the base plate 212 can also be connected and fixed by snaps, bolts, etc., making disassembly and assembly more convenient. In another embodiment, a sealing ring is provided between the housing 211 and the base plate 212, and one of the housing 211 and the base plate 212 is provided with a sealing groove. The sealing ring protrudes from the sealing groove to seal the connection between the housing 211 and the base plate 212.

[0057] In one embodiment of this utility model, reference is made to Figure 2 A base plate 212 is disposed between the housing 211 and the control plate 300, and a heat insulation member 400 is disposed between the base plate 212 and the control plate 300. The base plate 212 has a mounting surface 213 facing the heat insulation member 400, and the heating film 220 is disposed on the mounting surface 213. Thus, the heat insulation member 400 is disposed between the heating film 220 and the control plate 300, resulting in a shorter distance between them, facilitating electrical connection between them. Simultaneously, the heat insulation member 400 can mitigate the adverse effects of the high temperature generated by the heating film 220 during heating on the control plate 300.

[0058] In one embodiment of this invention, the heating film 220 is sintered and attached to the mounting surface 213. The heating film 220 is directly attached to the mounting surface 213 of the heating shell 210, eliminating the need for additional installation space and thus improving the overall space utilization of the vehicle. Furthermore, the low thermal resistance between the heating film 220 and the heating shell 210 results in high heat transfer efficiency, allowing for faster heat transfer to the heating shell 210 and subsequent heating of the coolant, thereby improving heating efficiency. Simultaneously, the heating film 220 can be designed as a large-area planar structure, resulting in more uniform heat distribution and preventing localized overheating of the heating shell 210, thus improving heating uniformity. In addition, the sintering process firmly attaches the heating film 220 to the heating shell 210, reducing the complex fixing structure and connectors found in traditional heaters 200, simplifying the overall structure. The sintering process also improves the weather resistance and reliability of the connection between the heating film 220 and the heating shell 210, better adapting to various harsh environments.

[0059] In one embodiment of this utility model, reference is made to Figure 4 The heating film 220 is provided with a connecting electrode 280, which electrically connects the heating film 220 and the control board 300. The heat insulation component 400 is provided with a clearance 410, through which the connecting electrode 280 passes. It can be understood that by passing the connecting electrode 280 through the clearance 410, the electrical connection between the heating film 220 and the control board 300 can be easily achieved, enabling the supply of electrical energy to the heating film 220 and controlling its operating state.

[0060] In one embodiment of this utility model, reference is made to Figures 4 to 6 The heater 200 also includes an inlet pipe 230, which is connected to the inlet port 260. Coolant at lower temperatures from the thermal management system can be delivered to the heating chamber through the inlet pipe 230. The inlet direction of the inlet pipe 230 is parallel or perpendicular to the axis of the compressor body 100, allowing for flexible adjustment based on specific vehicle layout and space constraints, thus improving adaptability.

[0061] And / or, the heater 200 also includes a coolant outlet pipe 240, which connects to a coolant outlet 270, for discharging the heated coolant from the heating chamber back into the thermal management system for use in vehicle interior heating or battery heating, etc. The discharge direction of the coolant outlet pipe 240 is parallel or perpendicular to the axis of the compressor body 100, and can be optimized according to the overall vehicle layout requirements to ensure smooth coolant flow.

[0062] In one embodiment of this utility model, reference is made to Figure 6The heater 200 also includes a turbulence structure 250 disposed inside the heating chamber. The turbulence structure 250 has multiple spaced-apart turbulence sections, with flow gaps formed between the multiple turbulence sections. This lengthens the flow path of the coolant inside the heating chamber, thus increasing the heating time and effectively improving heat transfer efficiency for better cooling. With the same heat transfer efficiency, the overall size of the heater 200 in this embodiment can be made smaller, further improving the structural compactness.

[0063] In one embodiment of this utility model, the turbulence-disrupting part is a turbulence-disrupting protrusion disposed on the inner surface of the heating cavity; or, the turbulence-disrupting part is a turbulence-disrupting fin separately disposed from the heating shell 210. It is understood that in one embodiment, the turbulence-disrupting part is a turbulence-disrupting protrusion integrally disposed with the heating shell 210, thus reducing the number of parts and lowering assembly difficulty and production costs. In another embodiment, the turbulence-disrupting part is a turbulence-disrupting fin assembled in the heating cavity, thus facilitating disassembly and maintenance.

[0064] In one embodiment of this utility model, the compressor assembly further includes a sealing gasket 500. The heater 200 is sealed to the compressor body 100 via the sealing gasket 500, thereby achieving a seal in the electrical control cavity, preventing dust, moisture, etc., from entering the electrical control cavity, and improving the stability of the control board 300's operation. In one embodiment, the base plate 212 and the compressor body 100 are connected, which can be fixed by bolts or welding, and is not limited thereto. Optionally, the groove opening of the mounting slot 110 is provided with a sealing gasket 500, and the heater 200 is disposed in the groove opening of the mounting slot 110 via the sealing gasket 500.

[0065] And / or, the heater 200 and the compressor body 100 cooperate to clamp the heat insulation component 400, thereby achieving the fixation of the heat insulation component 400.
