Therefore, they should not be construed as limitations on this utility model. Furthermore, if terms such as "first" and "second" appear, they are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] This embodiment relates to a vehicle thermal management system to solve the problems of large space occupation, large number of parts and high production cost of thermal management systems in the prior art.

[0036] Overall, the vehicle thermal management system in this embodiment includes a compressor 1, an evaporator 3, and a water heater 2. The evaporator 3 is spaced apart from the compressor 1, with a mounting space formed between them. The outlet 302 of the refrigeration chamber of the evaporator 3 extends toward the compressor's air inlet 101, making contact with and directly communicating with the compressor's air inlet 101.

[0037] In this embodiment, the water-heating heater 2 is located in the installation space and is installed on the compressor 1. The water-heating heater 2 and the heating chamber of the evaporator 3 constitute a heating circuit, and the liquid outlet 201 of the water-heating heater and the liquid inlet 303 of the heating chamber of the evaporator 3 are in contact with each other and directly connected, and the liquid inlet 202 of the water-heating heater is connected to the liquid outlet 304 of the heating chamber.

[0038] The vehicle thermal management system described in this embodiment is configured such that the water heater 2 is arranged in the installation space between the evaporator 3 and the compressor 1, and the outlet of the refrigeration chamber of the evaporator 3 is in contact with and directly connected to the air inlet 101 of the compressor, and the liquid outlet 201 of the water heater is in contact with and directly connected to the liquid inlet 303 of the heating chamber of the evaporator 3. This can eliminate the need for pipelines between the evaporator 3 and the compressor 1, as well as the need for pipelines between the water heater 2 and the heating chamber of the evaporator 3, thereby reducing the use of pipelines and facilitating the integration of components of the vehicle thermal management system into the arrangement of the compressor 1, thereby reducing the amount of space occupied in the vehicle.

[0039] Based on the above overall introduction, an exemplary structure of the vehicle thermal management system described in this embodiment is as follows: Figure 1 The compressor 1 is preferably arranged horizontally. Figure 1 Using the perspective shown in Figure 1 as a reference, the compressor's air inlet 101 is located at the bottom of the left end, and the water heater 2 is installed on the left end of the compressor 1. During installation, the water heater 2 can be connected to the compressor 1 using welding or fasteners such as bolts, as long as the layout requirements of the water heater 2 are met. When installed, one side of the water heater 2 can rest against the left end face of the compressor 1.

[0040] As a preferred embodiment, a control box 103 is provided at one end of the compressor 1 near the water heater 2. The water heater 2 has a substantially similar structure to conventional water heaters 2. The water heater's liquid inlet 202 and outlet 201 are both connected to the cavity to facilitate the flow of coolant.

[0041] As an example of a structure, the cavity within water heater 2 is formed by a first housing positioned near control box 103 and a second housing positioned on the other side of the first housing. The shape of the cavity formed between the first and second housings can be similar to that of water heaters 2 in the prior art. After cooling, the coolant flows back into the cavity, where it can be heated and then flow out.

[0042] In this embodiment, the first housing is made of nylon, and the second housing is made of metal. The electric heating assembly in the water heater 2 is located within the cavity and is used to heat the coolant flowing into the cavity. For example, the second housing can be made of aluminum alloy. Since the nylon first housing has poor thermal conductivity, this helps reduce the transfer of heat from the water heater 2 to the control box 103, thereby improving the safety of the control box 103. Of course, in addition to nylon, the first housing can also be made of other materials with poor thermal conductivity.

[0043] In addition, in order to improve the performance of the water-heating heater 2, an outer shell can be provided outside the first shell and the second shell, and the liquid inlet 202 and the liquid outlet 201 of the water-heating heater are both extended out of the outer shell. The water-heating heater 2 is specifically installed on the compressor 1 through the connection between the outer shell and the left end cover of the compressor 1.

[0044] In this embodiment, the control assembly of water heater 2 and the controller of compressor 1 are both located within control box 103, and the control assembly is electrically connected to the electric heating assembly within water heater 2. This facilitates the integrated layout of the control structure. In practice, the control assembly and the controller can share components such as high-voltage filtering, low-voltage filtering, power supply, MCU, and connectors. This further reduces the number of wiring harnesses and electrical components, thereby lowering production costs.

[0045] In addition, the control box 103 is provided with a wiring harness hole. The control assembly is electrically connected to the electric heating assembly via a wiring harness passing through the wiring harness hole. A seal is provided between the wiring harness and the wiring harness hole. This seal prevents foreign matter from entering the control box 103, further improving the safety of the control structure. In practice, the seal can be made of rubber for better sealing and ease of layout and implementation.

[0046] The evaporator 3 in this embodiment can be a plate-exchange evaporator 3 known in the prior art, having a refrigeration chamber and a heating chamber separated from each other. Refrigerant flows through the refrigeration chamber, and coolant flows through the heating chamber. The refrigeration chamber outlet 302 is positioned to correspond to the compressor's air inlet 101. By extending the refrigeration chamber outlet 302 toward the compressor's air inlet 101, the two can be connected by welding or other means, allowing the bottom of the evaporator 3 to be mounted on the compressor 1.

[0047] The liquid inlet 303 of the heating chamber of the evaporator 3 and the liquid outlet 201 of the water heater are both located at the top of each other, and can be connected to each other through welding or a clamping device. The liquid outlet 304 of the heating chamber and the liquid inlet 202 of the water heater are connected via a third pipeline. In this embodiment, the bottom of the evaporator 3 is directly connected to the compressor 1, and the top is connected to the compressor 1 through the water heater 2, making the connection between the three reliable and stable.

[0048] Still refer to Figure 1 As shown in , the vehicle thermal management system in this embodiment further includes a throttling device 4 and a condenser 5. The throttling device outlet 402 is in direct contact with the refrigeration chamber inlet 301 and is in direct communication with each other. The throttling device inlet 401 is in direct communication with the compressor exhaust port 102 via the condenser 5. Furthermore, the compressor 1, condenser 5, throttling device 4, and refrigeration chamber are connected in series to form a refrigeration circuit.

[0049] Here, the outlet 402 of the throttling device is in direct contact with the inlet 301 of the refrigeration chamber, thereby eliminating the need for piping between the throttling device 4 and the refrigeration chamber, further reducing production costs and space usage. In practice, the throttling device 4 can be an expansion valve, which is a mature product, easy to install, and has good performance. The outlet of the expansion valve and the inlet 301 of the refrigeration chamber are butted together and can be connected by welding.

[0050] The condenser 5 may be a plate-type condenser 5 known in the prior art, having a first heat exchange chamber and a second heat exchange chamber separated from each other. Refrigerant flows through the first heat exchange chamber, and coolant flows through the second heat exchange chamber. The first heat exchange chamber is connected in series to the refrigeration circuit.

[0051] As a feasible embodiment of the condenser 5, Figure 1 As shown in FIG, the inlet 502 of the condenser and the inlet 401 of the throttling device are in direct contact with each other, and the inlet 502 of the condenser is in direct contact with the exhaust port 102 of the compressor via a pipeline. In other words, the outlet of the first heat exchange chamber and the inlet 401 of the throttling device are in direct contact with each other, and the outlet of the first heat exchange chamber is in direct contact with the exhaust port 102 of the compressor via the first pipeline 6.

[0052] The outlet of the first heat exchange chamber is located at the top of the condenser 5, butted against the inlet 401 of the throttling device and fixed together by welding or clamping. This arrangement eliminates the need for piping between the condenser 5 and the throttling device 4, allowing the condenser 5, throttling device 4, evaporator 3, and water heater 2 to be integrated on the left side of the compressor 1, further improving the structural integration of the thermal management system.

[0053] Furthermore, an insulation layer is provided between the condenser 5 and the evaporator 3. This arrangement helps reduce heat exchange between the two, thereby improving the performance of the condenser 5 and the evaporator 3. In practice, the insulation layer can be made of any insulating material, such as rock wool board. In addition to providing an insulation layer, the distance between the condenser 5 and the evaporator 3 can also be increased to improve air thermal resistance.

[0054] As another feasible arrangement of the condenser 5, Figure 2 As shown in FIG, the inlet 501 of the condenser and the exhaust port 102 of the compressor are in direct contact with each other, and the inlet 502 of the condenser is connected to the inlet 401 of the throttling device via a pipeline. In other words, the inlet of the first heat exchange chamber and the exhaust port 102 of the compressor are in direct contact with each other, and the outlet of the first heat exchange chamber is connected to the inlet 401 of the throttling device via the second pipeline 7. The exhaust port 102 of the compressor and the inlet of the first heat exchange chamber are arranged correspondingly, and the connection is achieved by welding the two after they are butted together.

[0055] In this embodiment, the condenser inlet 502 and the throttling device inlet 401 are in direct contact and communication with each other, eliminating the need for piping between them. This reduces the number of components and production costs. Furthermore, the evaporator 3 and condenser 5 are located on the left and right sides of the compressor 1, thereby preventing heat loss caused by their proximity.

[0056] In addition, the air inlet 101 of the compressor can also be located at the top of the left end of the compressor 1. In this case, Figure 3 As shown in , the water heater 2, evaporator 3, and throttling device 4 are all arranged horizontally. In this case, the water heater 2 remains within the installation space defined between the evaporator 3 and the top of the compressor 1. Furthermore, the water heater 2, evaporator 3, and throttling device 4 are integrated at the top of the compressor 1, while the condenser 5 is integrated at the right end of the compressor 1. This arrangement reduces the axial space occupied by the compressor 1 and achieves a better integration effect.

[0057] The vehicle thermal management system described in this embodiment can solve the problems of complex structure and high cost of thermal management systems in the prior art by integrating multiple components on the compressor 1 and eliminating the need for some pipelines. It can also reduce the space occupied by the vehicle thermal management system and facilitate its layout and installation on the vehicle.

[0058] In addition, this embodiment also relates to a vehicle, which is equipped with the vehicle thermal management system as described above.

[0059] The vehicle described in this embodiment, by providing the above-mentioned vehicle thermal management system, can reduce production costs while also helping to reduce the amount of space occupied within the vehicle.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
