[0024] Heaters, as a key component of thermal management systems, are widely used in various equipment and applications, including automobiles. Traditional heaters typically consist of a housing and a base plate fixed together using metal-to-metal joining techniques such as brazing to form a heating chamber. However, when brazing or welding the housing and base plate, clamps are usually required for pre-tightening. This method not only increases manufacturing costs but also complicates the production process and reduces efficiency. Furthermore, a set of clamps is expensive, and the clamps absorb a significant amount of heat during brazing or welding, resulting in substantial heat loss during assembly and poor economic efficiency.

[0025] In view of this, the present invention provides a compressor assembly, a thermal management system, and an automobile. Through the pre-positioning structure, the base plate and the housing can be positioned before welding and fixing the housing and the base plate, eliminating the use of special assembly tools such as jigs. No professional skills and experience are required during assembly, making the operation simpler and reducing the complexity of the assembly process and manufacturing cost between the base plate and the housing.

[0026] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 as well as Figure 7 As shown, this utility model embodiment proposes a compressor assembly, which includes: The compressor body 200 can adopt a commonly used design structure, and the embodiments of this application are not limited thereto. A heater 100 is located at one end of the compressor body 200 and forms an electrical control cavity with the compressor body 200. That is, the heater 100 is integrated with the electrical control box of the compressor body 200, eliminating the need for a separate heater 100. The space within the original electrical control box cover is used to integrate the heater 100, effectively reducing space occupation and the overall size of the thermal management system. The heater 100 includes a housing 111 and a base plate 112, which together form a heating cavity for heating the incoming coolant. In other words, the housing 111 and the base plate 112 form a heating shell 110, with the heating cavity inside. A pre-positioning structure 130 is provided between the housing 111 and the base plate 112 to ensure a pre-positioned installation followed by welding and sealing. It is understood that the housing 111 and the base plate 112 achieve a tight and reliable connection through a welding structure. The pre-positioning structure 130 pre-fixes or positions the base plate 112 and housing 111 before the welding structure secures them, preventing movement of parts during the metal connection process and improving welding accuracy. In one embodiment, the pre-positioning structure 130 can be a snap-fit ​​structure, bolt structure, or protrusion structure, etc., and is not limited thereto. The control board 300 is located in the electrical control cavity and is electrically connected to the compressor body 200 and the heater 100. It can be understood that the heater 100 is electrically connected to the control board 300 through electrodes or wires, and the compressor body 200 is electrically connected to the control board 300 through wires. The operation of the heater 100 and the compressor body 200 can be controlled simultaneously through a single control board 300, which is more convenient.

[0028] In the technical solution adopted in this embodiment, the pre-positioning structure 130 allows for pre-fixing or positioning of the base plate 112 and the housing 111 before the welding structure is fixedly connected, preventing displacement between them during welding and improving product yield. Furthermore, the use of specialized assembly tools such as jigs is eliminated, requiring no specialized skills or experience during assembly, simplifying the process and reducing the complexity of the assembly process between the base plate 112 and the housing 111. Simultaneously, the compressor body 200 and the heater 100 cooperate to form an electrical control cavity, with the heater 100 replacing the original cover of the compressor's electrical control box. That is, the heater 100 is integrated with the electrical control box of the compressor body 200, eliminating the need for a separate heater 100. Utilizing the space of the original electrical control box cover to integrate the heater 100 effectively reduces space occupation and the overall size of the thermal management system.

[0029] In one embodiment of this utility model, reference is made to Figures 3 to 6 The pre-positioning structure 130 includes a positioning head 131 and a positioning notch 132 that mates with the positioning head 131. One of the housing 111 and the base plate 112 is provided with the positioning head 131, and the other of the housing 111 and the base plate 112 is provided with the positioning notch 132. It is understood that by engaging the positioning head 131 into the positioning notch 132, pre-fixing or pre-pressing of the base plate 112 and the housing 111 can be achieved. Optionally, the positioning head 131 and the positioning notch 132 are shape-fitted. In one embodiment, the positioning head 131 and the positioning notch 132 are interference-fitted, which can improve the reliability of pre-fixing.

[0030] In one embodiment of this utility model, reference is made to Figure 9 The positioning head 131 includes a first positioning part 1311, a second positioning part 1312, and a third positioning part 1313, which are bent and connected. The first positioning part 1311 and the third positioning part 1313 are located on opposite sides of the second positioning part 1312. The second positioning part 1312 is inserted into the positioning notch 132, and the first positioning part 1311 and the third positioning part 1313 abut against opposite sides of the positioning notch 132. In this embodiment, one end of the first positioning part 1311 is bent and connected to the housing 111. The first positioning part 1311 and the third positioning part 1313 are located on opposite sides of the base plate 112. When the second positioning part 1312 is engaged with the positioning notch 132, the first positioning part 1311 and the third positioning part 1313 cooperate to clamp the base plate 112, thereby achieving the pre-fixation of the base plate 112 and the housing 111.

[0031] In one embodiment of this utility model, the first positioning part 1311 and the third positioning part 1313 are arranged in parallel, which can evenly apply pressure to both sides of the base plate 112, helping to improve the accuracy and consistency of assembly. Furthermore, in the direction in which the second positioning part 1312 inserts into the positioning notch 132, the extension length of the first positioning part 1311 is greater than the extension length of the third positioning part 1313. The longer first positioning part 1311 increases the contact area with the base plate 112 during installation, providing stronger support, while the shorter third positioning part 1313 facilitates the alignment of the second positioning part 1312 with the positioning notch 132, making it easier for the second positioning part 1312 to quickly and accurately engage in the positioning notch 132.

[0032] In one embodiment of this utility model, reference is made to Figure 4 and Figure 10 The heater 100 also includes a liquid inlet pipe 161. The housing 111 is provided with a liquid inlet, and the liquid inlet pipe 161 is connected to the liquid inlet. The liquid inlet pipe 161 can deliver the coolant with a lower temperature in the thermal management system to the heating chamber. The liquid inlet direction of the liquid inlet pipe 161 is parallel or perpendicular to the axis of the compressor body 200, which can be flexibly adjusted according to the specific vehicle layout and space constraints, thus improving adaptability.

[0033] And / or, the heater 100 also includes a coolant outlet pipe 162. The base plate 112 is provided with a coolant outlet, and the coolant outlet pipe 162 is connected to the coolant outlet 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 162 is parallel or perpendicular to the axis of the compressor body 200, which can be optimized according to the overall vehicle layout requirements to ensure smooth coolant flow.

[0034] In one embodiment of this utility model, reference is made to Figure 6 and Figure 8 The heater 100 also includes a turbulence structure 150 disposed inside the heating chamber. The turbulence structure 150 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 100 in this embodiment can be made smaller, further improving the structural compactness.

[0035] In one embodiment of this utility model, the turbulence structure 150 is a turbulence protrusion disposed on the inner surface of the heating cavity; or, the turbulence part is a turbulence fin separately disposed from the heating cavity. It is understood that in one embodiment, the turbulence structure 150 is a turbulence protrusion, which is integrally disposed with the housing 111 or the base plate 112, thus reducing the number of parts and lowering assembly difficulty and production costs. In another embodiment, the turbulence structure 150 is a turbulence fin, which is assembled in the heating cavity, thus facilitating disassembly and maintenance.

[0036] In one embodiment of this utility model, a base plate 112 is disposed between the housing 111 and the control plate 300. The base plate 112 has a mounting surface 113 facing the control plate 300, and a heating element 120 is disposed on the mounting surface 113. This results in a shorter distance between the heating element 120 and the control plate 300, facilitating electrical connection between them. A heat insulation member 400 is provided between the base plate 112 and the control plate 300. Figure 2 and Figure 10 It is understandable that the heat insulation component 400 can isolate the heat generated by the heating element 120 during operation, reduce the heat transferred to the control board 300, prevent the temperature of the control board 300 from rising too quickly and affecting normal operation, thereby reducing the adverse effects of the high temperature of the heating element 120 on the control board 300.

[0037] In one embodiment of this utility model, the heating element 120 is a heating film. It is understood that compared to traditional heating components, the heating film is lighter, reducing the weight of the heater 100 and thus the overall weight of the vehicle, improving the driving range of the electric vehicle. Simultaneously, due to the efficient heating characteristics of the heating film, the required heating effect can be achieved with lower energy consumption, helping to reduce the overall energy consumption of the electric vehicle. It is understood that the heating film generates heat when energized, and the heat is conducted to the heating shell 110, thereby heating the coolant. Optionally, the heating film is sintered and attached to the outer surface of the base plate 112, i.e., the surface facing the control board 300. This securely attaches the heating film to the base plate 112, reducing the complex fixing structure and connectors found in traditional heaters 100, simplifying the overall structure. The sintering process improves the weather resistance and reliability of the connection between the heating film and the base plate 112, better adapting to various harsh environments. The heating film is provided with a connecting electrode 140, as shown in the figure. Figure 2 and Figure 10 The connecting electrode 140 electrically connects the heating film and the control board 300. The heat insulation component 400 has a clearance 410 through which the connecting electrode 140 passes. Thus, the connecting electrode 140 can pass through the heat insulation component 400 from the clearance 410, thereby achieving electrical connection between the heating film and the control board 300. Specifically, the heat insulation component 400 can be a plate-like structure made of fiberglass, asbestos, rock wool, etc.
