[0036] With increasing global emphasis on environmental protection and sustainable development, new energy vehicles (including pure electric vehicles and plug-in hybrid electric vehicles) are gradually becoming the mainstream in the automotive market. Thermal management systems, as a crucial component of new energy vehicles, play a key role in vehicle performance, battery life, and passenger comfort.

[0037] The inventors discovered that current thermal management systems typically employ a separate design for the compressor and heater, installed in different locations within the vehicle and connected via wiring harnesses and pipes. This approach occupies considerable space, resulting in low vehicle space utilization and increased costs. Furthermore, existing thermal management systems often utilize PTC electric heaters, which have complex structures and large volumes, further increasing space requirements and incurring high operating costs.

[0038] In view of this, the present invention provides a compressor assembly, a thermal management system, and an automobile. By placing an electromagnetic induction heater at one end of the compressor body and forming an electronic control cavity together with the compressor body, the compressor body and the electromagnetic induction heater are integrated, reducing additional connecting parts and pipes. The compressor body and the heater no longer occupy a large amount of space separately, making the entire system more compact and reducing space occupation. This provides more installation space for other vehicle-mounted equipment, significantly improving space utilization and helping to optimize the overall layout of the vehicle. Moreover, the integrated design reduces unnecessary weight, helping to reduce the overall weight of new energy vehicles, thereby improving the vehicle's energy efficiency and power performance.

[0039] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, this utility model embodiment proposes a compressor assembly, the compressor assembly comprising:

[0041] The compressor body 100 is used to compress and transport refrigerant. The compressor body 100 can adopt a commonly used design structure, and the embodiments of this application are not limited here.

[0042] An electromagnetic induction heater 200 is located at one end of the compressor body 100 and forms an electronic control cavity 400 with the compressor body 100. The electromagnetic induction heater 200 has an electromagnetic heating channel 211, a liquid inlet 212, and a liquid outlet 213, both of which are connected to the electromagnetic heating channel 211. Specifically, the electromagnetic induction heater 200 is located at one end of the compressor body 100 and can be integrally installed or separately assembled; no limitation is made here. The heat exchange medium can enter the electromagnetic heating channel 211 through the liquid inlet 212, be heated in the electromagnetic heating channel 211, and then flow out of the electromagnetic heating channel 211 through the liquid outlet 213, being delivered to the load to realize the cooling, heating, or heat dissipation functions of the thermal management system; and

[0043] A control component is located in the electrical control cavity 400. Both the compressor body 100 and the electromagnetic induction heater 200 are electrically connected to the control component. Specifically, the electromagnetic induction heater 200 is electrically connected to the control component via electrodes or wires, and the compressor body 100 is electrically connected to the control component via wires. A single control component can simultaneously control the operation of both the electromagnetic induction heater 200 and the compressor body 100, simplifying the control system and making operation more convenient. It is understood that the compressor body 100 has a motor, which is electrically connected to the control component.

[0044] In this embodiment, by placing the electromagnetic induction heater 200 at one end of the compressor body 100 and forming an electrical control cavity 400 together with the compressor body 100, the compressor body 100 and the electromagnetic induction heater 200 are integrated. This reduces additional connectors and pipes, and the compressor body 100 and the heater no longer occupy a large amount of space separately, making the entire system more compact and smaller, reducing space occupation, providing more installation space for other vehicle-mounted equipment, significantly improving space utilization, and helping to optimize the overall vehicle layout. Moreover, the electromagnetic induction heater 200 used in this application has higher energy conversion efficiency and faster heating speed compared to traditional PTC electric heaters, and its structure is simpler, further reducing space occupation. At the same time, placing the control components within the electrical control cavity 400 enables integrated control of the compressor body 100 and the electromagnetic induction heater 200, which helps simplify the control system, reduce the complexity of electrical connections, and improve the reliability and stability of the system.

[0045] In one embodiment of this utility model, the electronic control cavity 400 is formed at one end of the compressor body 100 and has an opening facing away from the compressor body 100. The electromagnetic induction heater 200 covers the opening. It can be understood that the electronic control cavity 400 is located at the end of the compressor body 100, and the electromagnetic induction heater 200 is located at the opening of the electronic control cavity 400 and is adapted to the outer contour of the opening, thus sealing the opening of the electronic control cavity 400 and closing it. In other words, the electromagnetic induction heater 200 replaces the original cover of the compressor's electronic control box. That is, the electromagnetic induction heater 200 is integrated with the electronic control cavity 400 of the compressor body 100, eliminating the need for a separate electromagnetic induction heater 200. Utilizing the space of the original electronic control box cover to integrate the electromagnetic induction heater 200 effectively reduces space occupation, decreases the size of the entire thermal management system, and facilitates optimization of the vehicle's overall layout.

[0046] In one embodiment of this utility model, reference is made to Figure 2The electromagnetic induction heater 200 includes a cover 220 that covers the opening, and an electromagnetic heating device 230 disposed within the cover 220. The liquid inlet 212 and liquid outlet 213 are both located within the cover 220, and the electromagnetic heating device 230 contains an electromagnetic heating channel 211. Specifically, by placing the electromagnetic heating device 230 within the cover 220, the overall structure of the electromagnetic induction heater 200 is simple and compact, easy to install and integrate. Furthermore, the cover 220 can also shield the magnetic field, reducing adverse effects on other power devices. In addition, the sealed structure of the cover 220 effectively prevents external dust, moisture, and other impurities from entering the interior of the electromagnetic induction heater 200, thereby ensuring stable system operation and a longer service life. It is understood that the cover 220 simultaneously achieves sealing and shielding functions, further reducing structural complexity. In one embodiment, the cover 220 is integrally formed with the compressor body 100, thus improving structural strength. Of course, in other embodiments, the housing 220 can also be bolted to the compressor body 100, which can improve the convenience of disassembly and assembly. In another embodiment, the inner wall surface of the housing 220 is provided with a shielding coating, which can further reduce the electromagnetic interference of the magnetic field of the electromagnetic heating device 230 on other electronic components.

[0047] In one embodiment of this utility model, reference is made to Figure 2 The electromagnetic heating device 230 includes:

[0048] The heating element 231 is disposed within the housing 220. It is understood that the heating element extends from the liquid inlet 212 towards the liquid outlet 213, meaning the heating element 231 is vertically positioned between the liquid inlet 212 and the liquid outlet 213. The heating element is made of a magnetically, electrically, and thermally conductive material, such as stainless steel, capable of cutting magnetic field lines to generate heat, thereby directly heating the heat exchange medium. In one embodiment, the heating element and the housing 220 are insulated from each other; an insulating element can be provided at the end of the heating element, which is then fixed to the housing 220.

[0049] An insulating sleeve 232 is fitted over the outside of the heating element 231. The insulating sleeve 232 and the heating element 231 are spaced apart to form the electromagnetic heating channel 211, which electrically isolates the heating element and the electromagnetic coil 233, thus providing electrical insulation.

[0050] An electromagnetic coil 233 is wound around the outer periphery of the insulating sleeve 232 and electrically connected to the control component. The electromagnetic coil 233 can generate a magnetic field when energized, which, in conjunction with the heating element, generates heat through electromagnetic induction. The heat generated on the heating element 231 can directly heat the heat exchange medium flowing through the electromagnetic heating channel 211. Furthermore, the generated heat can be evenly distributed on the heating element, improving heating uniformity and preventing localized overheating.

[0051] In one embodiment of this utility model, reference is made to Figure 2 The outer peripheral surface of the heating element 231 is provided with multiple turbulence protrusions 234 spaced apart, and a flow gap is formed between two adjacent turbulence protrusions 234. This lengthens the effective flow path of the heat exchange medium inside the electromagnetic heating channel 211, thus increasing the heating time and effectively improving heat transfer efficiency and heating the heat exchange medium better. With the same heat transfer efficiency, the overall size of the electromagnetic induction heating device in this embodiment can be made smaller, further improving the structural compactness. Furthermore, the multiple turbulence protrusions 234 on the outer peripheral surface of the heating element 231 increase the contact area between the heating element 231 and the heat exchange medium, thereby improving heat transfer efficiency. In one embodiment, the turbulence protrusions 234 are integrally formed with the heating element, which reduces the number of parts, lowers assembly difficulty, and reduces production costs.

[0052] In one embodiment of this invention, a plurality of the turbulence protrusions 234 are spirally arranged on the outer peripheral surface of the heating element 231. Specifically, the spiral turbulence protrusions 234 enable the heat exchange medium to form an effective turbulence effect during flow, further enhancing heat exchange performance. Moreover, the heat exchange medium can more evenly contact all parts of the heating element 231 during flow, reducing the occurrence of local overheating or underheating, and effectively improving the uniformity of heating effect. At the same time, compared with the traditional inline turbulence protrusions 234, the spiral turbulence protrusions 234 can better guide the flow of the heat exchange medium, reduce the flow resistance of the heat exchange medium, reduce the dependence of the heat exchange medium on the pump, reduce system energy consumption, and improve energy utilization efficiency.

[0053] In one embodiment of this utility model, multiple electromagnetic heating devices 230 are provided, and the electromagnetic heating channels 211 of the multiple electromagnetic heating devices 230 are arranged in parallel between the liquid inlet 212 and the liquid outlet 213. It can be understood that each electromagnetic heating device 230 forms at least one electromagnetic heating channel 211, and the heat exchange medium flowing in from the liquid inlet 212 can be divided into multiple paths for simultaneous heating. That is, multiple parallel electromagnetic heating channels 211 can heat the fluid simultaneously, effectively shortening the heating time and rapidly responding to temperature changes, thus meeting the demand for rapid heating. Moreover, the flow velocity of the heat exchange medium in each electromagnetic heating channel 211 is relatively low, reducing the resistance of the heat exchange medium within the electromagnetic heating channel 211 and helping to reduce pressure drop. In addition, the multiple parallel electromagnetic heating channels 211 increase the total effective heat transfer area and improve heating efficiency.

[0054] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3 The housing 220 includes a cover body 221 connected to the opening and an end cap 222 connected to the cover body 221. The electromagnetic heating device 230, the liquid inlet 212, and the liquid outlet 213 are all located on the cover body 221. It is understood that the housing 220 includes a cover body 221 and an end cap 222. One end of the cover body 221 is connected to and covers the opening, and the other end of the cover body 221 is connected to the end cap 222. During assembly, the electromagnetic heating device 230 can be installed on the cover body 221 first, and then the end cap 222 can be installed on the cover body 221, thus improving assembly convenience. That is, the end of the cover body 221 facing away from the opening is the mounting port, and the end cap 222 is fitted onto the mounting port. Optionally, the end cap 222 and the cover body 221 can be connected by bolts, snap-fit ​​connections, or welding, etc., which is not limited here.

[0055] In one embodiment of this utility model, reference is made to Figure 4 The electrical control cavity 400 has an expansion portion that protrudes laterally from the side of the compressor body 100. An electrical connector 300 is provided on the surface of the expansion portion opposite to the electromagnetic induction heater 200. The electrical connector 300 electrically connects the electromagnetic induction heater 200 and the control component. Specifically, the expansion portion allows the electrical connector 300 to protrude laterally, facilitating its connection and operation during installation and maintenance. Furthermore, it helps isolate the electromagnetic induction heater 200 from external electronic components, reducing electromagnetic interference and improving the system's electromagnetic compatibility.

Specifically, the specific structure of the compressor assembly refers to the above embodiments. Since this thermal management system adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here. Optionally, refer to... Figure 5 The electromagnetic induction heater 200 can be connected to the water-side heat exchange system in the thermal management system. The heat exchange medium flowing through the electromagnetic induction heater 200 is heated and then driven by a water pump and connected to a multi-way valve. It can be connected to other different loads such as the heater core, battery, outdoor low-temperature radiator, and water-cooled evaporator to achieve different functional requirements such as cooling, heat dissipation or heating.
