ERVs utilize both batteries and engines as their power sources. The battery serves as the primary power source, providing electricity to drive the electric motor, enabling the vehicle to operate in pure electric mode. When the battery charge is low, the engine starts and drives the generator to charge the battery, thereby extending the vehicle's range. In ERVs, the thermal management system can develop corresponding control strategies based on the actual operating conditions of the battery, ensuring that the battery operates within the optimal temperature range under different operating conditions, thereby ensuring the ERV's operating efficiency.

[0054] As described in the background, the thermal management system for EREVs in related art solutions still uses the same structure as traditional fuel-powered vehicles, directly connecting heat exchange components such as the expansion valve, compressor, and evaporator through piping. However, due to the addition of components such as batteries and generators, the thermal management system requires corresponding piping connected to the batteries. This results in a complex piping structure for the EREV thermal management system, which takes up a significant amount of space in the engine compartment.

[0055] In view of this, the embodiments of the present application aim to provide a heat exchange module, a thermal management system and a vehicle, in which a first electronic expansion valve and a second electronic expansion valve are arranged on a base, a refrigerant flow channel is formed in the base, and the refrigerant inflow pipeline, the first electronic expansion valve and the second electronic expansion valve are all connected to the refrigerant flow channel, so that the refrigerant flow channel in the base can be used to replace the pipeline between the first electronic expansion valve and the second electronic expansion valve connected to the compressor, so as to reduce the number of pipelines in the thermal management system and save space in the cabin.

[0056] Below, embodiments of the present application are described in detail with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0057] The embodiment of the present application provides a heat exchange module for meeting the heat exchange requirements of components such as batteries and air-conditioning box evaporators in extended-range vehicles. It should be noted that the vehicle in this application may refer to a large vehicle, a small vehicle, a special vehicle, etc. For example, according to the vehicle model, the vehicle in this application may be a sedan model, an off-road vehicle model, a multi-purpose vehicle (MPV) model or other models. For a vehicle, wheels and a body are generally provided, and a cabin is provided at the front end of the body. The cabin is provided with components such as an engine and a thermal management system. The thermal management system can be installed on the front panel in the cabin to achieve fixation with the cabin. In an extended-range vehicle, the thermal management system can formulate a corresponding control strategy based on the actual working conditions of the battery, so that the battery works in the optimal temperature range under different working conditions, thereby ensuring the working efficiency of the extended-range vehicle.

[0058] Please refer to Figures 1-8 The present invention provides a heat exchange module according to an embodiment of the present invention, including a base 100, a refrigerant inlet pipe 200, a first electronic expansion valve 300, and a second electronic expansion valve 400. The first electronic expansion valve 300 and the second electronic expansion valve 400 are both disposed on the base 100. For example, the first electronic expansion valve 300 and the second electronic expansion valve 400 can be fixedly connected to the base 100 by fasteners to ensure the stability of the connection.

[0059] like Figure 5-Figure 8As shown, the surface of the base 100 is provided with a refrigerant inlet 101, a first liquid inlet 102, and a second liquid inlet 103. For example, the refrigerant inlet 101 can be located on one side of the base 100, and the first liquid inlet 102 and the second liquid inlet 103 can be located on the other side of the base 100, and the side where the first liquid inlet 102 and the second liquid inlet 103 are located is adjacent to the side where the refrigerant inlet 101 is located. A refrigerant flow channel 110 is formed in the base 100, and the refrigerant inlet 101, the first liquid inlet 102, and the second liquid inlet 103 are all connected to the refrigerant flow channel 110. The first end of the refrigerant inlet pipe 200 is used to connect to the compressor, and the second end of the refrigerant inlet pipe 200 is connected to the refrigerant flow channel 110 through the refrigerant inlet 101, so that the refrigerant output by the compressor is sent into the refrigerant flow channel 110. The first electronic expansion valve 300 is connected to the refrigerant flow channel 110 through the first liquid inlet 102, and the first electronic expansion valve 300 is used to control the heat exchange between the refrigerant and the evaporator. It is understood that part of the refrigerant entering the refrigerant flow channel 110 can be heat-exchanged with the evaporator in the air-conditioning box through the first electronic expansion valve 300, thereby realizing the air conditioning function in the vehicle cockpit. The second electronic expansion valve 400 is connected to the refrigerant flow channel 110 through the second liquid inlet 103, and the second electronic expansion valve 400 is used to control the heat exchange between the refrigerant and the battery cooler 500. It is understood that another part of the refrigerant entering the refrigerant flow channel 110 can be heat-exchanged with the battery cooler 500 through the second electronic expansion valve 400, thereby ensuring that the temperature of the battery is within the optimal temperature range and ensuring the operating efficiency of the extended-range vehicle.

[0060] From the above description, it can be seen that the embodiment of the present application arranges the first electronic expansion valve 300 and the second electronic expansion valve 400 on the base 100, and a refrigerant flow channel 110 is formed in the base 100. The refrigerant inlet pipeline 200, the first electronic expansion valve 300 and the second electronic expansion valve 400 are all connected to the refrigerant flow channel 110, so that the refrigerant flow channel 110 in the base 100 can be used to replace the first electronic expansion valve 300 and the second electronic expansion valve 400 to connect to the pipeline between the compressor, so as to reduce the number of pipelines in the thermal management system and save space in the cabin.

[0061] Please continue to refer to Figures 1-4 The heat exchange module of the embodiment of the present application also includes an evaporator inlet pipe 600 and an evaporator outlet pipe 700. The first end of the evaporator inlet pipe 600 is connected to the first electronic expansion valve 300, and the second end of the evaporator inlet pipe 600 is used to connect to the evaporator. The first end of the evaporator outflow pipe 700 is used to connect to the evaporator, and the second end of the evaporator outflow pipe 700 is used to connect to the compressor.

[0062] During vehicle operation, the refrigerant enters the evaporator inlet pipe 600 through the first electronic expansion valve 300. It then exchanges heat with the evaporator in the air conditioning unit through the evaporator inlet pipe 600, providing air conditioning for the vehicle's cabin. After heat exchange, the gaseous refrigerant flows back into the compressor through the evaporator outlet pipe 700, where it is compressed and continues to exchange heat.

[0063] In this embodiment of the present application, the first electronic expansion valve 300 is connected to the evaporator via the evaporator inlet pipe 600, thereby transferring the refrigerant to the evaporator for heat exchange, thereby achieving air conditioning in the vehicle's cockpit. After heat exchange, the gaseous refrigerant can flow back into the compressor through the evaporator outlet pipe 700 for subsequent heat exchange after compression, thus achieving refrigerant circulation.

[0064] Please refer to Figure 2 and Figure 3 The heat exchange module of the embodiment of the present application also includes a first pressure plate 800, on which an evaporator inlet interface 810 and an evaporator outlet interface 820 are formed. The second end of the evaporator inlet pipe 600 is connected to the evaporator through the evaporator inlet interface 810, and the first end of the evaporator outlet pipe 700 is connected to the evaporator through the evaporator outlet interface 820.

[0065] It can be understood that the embodiment of the present application integrates the evaporator inlet pipe 600 and the evaporator outlet pipe 700 on the first pressure plate 800 and connects with the evaporator through the first pressure plate 800, thereby improving assembly efficiency and reducing assembly time.

[0066] For example, the first pressing plate 800 is further provided with an evaporator fixing member 830, and the first pressing plate 800 is fixedly connected to the air conditioning box where the evaporator is located via the evaporator fixing member 830. The evaporator fixing member 830 can be, for example, a screw or bolt, and the first pressing plate 800 is detachably connected to the air conditioning box, thereby facilitating disassembly during installation and maintenance.

[0067] Please refer to Figure 5 In the embodiment of the present application, the base 100 is provided with a first fixing hole 104 and a second fixing hole 105. A first fastener passes through the first fixing hole 104 to be fixedly connected to the first electronic expansion valve 300, and a second fastener passes through the second fixing hole 105 to be fixedly connected to the second electronic expansion valve 400. For example, the first fixing hole 104 and the second fixing hole 105 can both be through holes, and the first fastener and the second fastener can both be screws or bolts. The first electronic expansion valve 300 and the second electronic expansion valve 400 are detachably connected to the base 100, thereby facilitating disassembly during installation and maintenance.

[0068] Please continue to refer to Figure 1-Figure 3The heat exchange module of the embodiment of the present application further includes a battery cooler 500 and a battery-side outflow pipe 900. The battery cooler 500 is located on the side of the second electronic expansion valve 400 away from the base 100; that is, the battery cooler 500 and the base 100 are located on opposite sides of the second electronic expansion valve 400. Figure 3 As shown, the second electronic expansion valve 400 includes a liquid outlet 410 and an air return port 420. The second electronic expansion valve 400 is connected to the battery cooler 500 through the liquid outlet 410 and the air return port 420, thereby realizing the flow of refrigerant between the second electronic expansion valve 400 and the battery cooler 500. Please continue to refer to Figure 5 、 Figure 6 and Figure 8 The surface of the base 100 of the embodiment of the present application is also provided with an expansion valve return port 106 and an air outlet 107, and a return air duct 120 is formed in the base 100. The second electronic expansion valve 400 is connected to the return air duct 120 through the expansion valve return port 106, and the first end of the battery side outflow pipe 900 is connected to the return air duct 120 through the air outlet 107. The second end of the battery side outflow pipe 900 is used to connect to the compressor.

[0069] During vehicle operation, the refrigerant enters the battery cooler 500 through the liquid outlet 410 of the second electronic expansion valve 400 for heat exchange, thereby reducing the battery temperature and ensuring the operating efficiency of the extended-range vehicle. After heat exchange, the gaseous refrigerant flows back to the second electronic expansion valve 400 through the return port 420, further flows back into the return flow channel 120 within the base 100 through the expansion valve return port 106, and then flows back to the battery-side outflow pipe 900 through the outlet port 107. Finally, it enters the compressor through the battery-side outflow pipe 900 for compression and subsequent heat exchange.

[0070] Through the above structure, the embodiment of the present application can save the refrigerant pipeline between the second electronic expansion valve 400 and the battery cooler 500, thereby facilitating further saving space in the cabin.

The second end of the evaporator outlet pipe 700 and the second end of the battery side outlet pipe 900 are both connected to the compressor through the compressor inlet interface 1010, and the first end of the refrigerant inlet pipe 200 is connected to the compressor through the compressor outlet interface 1020.

[0072] It can be understood that the embodiment of the present application integrates the evaporator outflow pipe 700, the battery side outflow pipe 900 and the refrigerant inflow pipe 200 on the second pressure plate 1000, and connects with the compressor through the second pressure plate 1000, thereby helping to improve assembly efficiency and reduce assembly time.

[0073] For example, the second pressure plate 1000 is further provided with a compressor fixing member 1030, and the second pressure plate 1000 is fixedly connected to the compressor via the compressor fixing member 1030. The compressor fixing member 1030 can be, for example, a screw or bolt, and the second pressure plate 1000 is detachably connected to the compressor, thereby facilitating disassembly during installation and maintenance.

[0074] Please continue to refer to Figure 5 In the embodiment of the present application, the base 100 is further provided with a third fixing hole 108. A third fastener passes through the third fixing hole 108 and the second electronic expansion valve 400 to securely connect the battery cooler 500. For example, the third fixing hole 108 can be a through hole, and the third fastener can be a screw or bolt. The second electronic expansion valve 400 and the battery cooler 500 are detachably connected to the base 100, thereby facilitating disassembly for installation and maintenance.

[0075] Please continue to refer to Figure 1 The heat exchange module of the embodiment of the present application also includes a first sensor 1100 and a second sensor 1200. The first sensor 1100 and the second sensor 1200 can both be PT sensors (sensors made of platinum material). The first sensor 1100 is arranged on the evaporator outlet pipe 700 and is arranged near the second end of the evaporator outlet pipe 700, and can be used to measure the temperature of the refrigerant in the evaporator outlet pipe 700.

A first signal interface 310 is provided on the first electronic expansion valve 300, and a second signal interface 430 is provided on the second electronic expansion valve 400. The first sensor 1100, the second sensor 1200, the first signal interface 310 and the second signal interface 430 are all used to communicate with the vehicle controller through a wiring harness.

[0076] Combine Figure 1 It can be seen that the embodiment of the present application integrates the first sensor 1100, the second sensor 1200, the first electronic expansion valve 300 and the second electronic expansion valve 400 near the base 100, so that the output positions of various electronic components are arranged in a centralized manner, which is beneficial to reducing the length and complexity of the wiring harness in the cabin, thereby improving assembly efficiency.
