Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and in particular to a vehicle heat exchange module, a vehicle temperature control system, and a vehicle. Background Technology

[0002] In related technologies, hybrid vehicles have a front-end heat exchange module at the front of the engine compartment for cooling the equipment in the vehicle. This module includes a water-cooled intercooler. The water-cooled intercooler is a device used to lower the temperature of the air entering the engine. If the air temperature at the outlet of the intercooler is too low, moisture in the air will condense, and this condensate may enter the engine, causing it to stall. To address this issue, related technologies can tilt the intercooler, for example, by setting the inlet higher than the outlet. When the condensate flows to the outlet, it will evaporate quickly, thus preventing some condensate from entering the engine. However, this does not completely eliminate the possibility of condensate entering the engine. Utility Model Content

[0003] This application provides a vehicle heat exchange module, a vehicle temperature control system, and a vehicle, aiming to improve the problem in related technologies that the possibility of condensation from water-cooled intercooler outlet air temperature being too low and entering the engine cannot be completely eliminated.

Detailed Implementation

[0012] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0013] To facilitate understanding of the technical solutions and effects of the embodiments of this application, the relevant technologies of this application will be briefly described below.

[0014] Hybrid vehicles are vehicles that combine an engine and an electric motor as power systems. These two power systems can work independently or in combination to drive the vehicle. Therefore, compared to vehicles driven solely by an engine, hybrid vehicles have increased cooling requirements. In addition to the original cooling needs of the engine, hybrid vehicles also have additional cooling requirements for electrical equipment and other components. In related technologies, a front-end heat exchange module is installed at the front of the engine compartment of a hybrid vehicle to cool its equipment. However, the front-end heat exchange module in this technology has at least the following problems:

[0015] (1) The design of the front face of the vehicle is increasingly focused on aesthetics and personalization, which makes the grille (opening) used for heat dissipation on the front face of the vehicle smaller and smaller, or even closed structure. This results in poor wind-side constraint of the front heat exchange module, that is, the way the front heat exchange module dissipates heat through air flow is subject to increasingly higher constraints, which makes it impossible to meet the heat dissipation requirements of hybrid vehicles.

[0016] To address this issue, related technologies can develop larger radiators and more powerful cooling fans to improve heat dissipation. However, larger radiators and more powerful cooling fans occupy more space in the vehicle, leading to increased costs, higher energy consumption, and deterioration of NVH performance. NVH refers to Noise, Vibration, and Harshness.

[0017] (2) The front-end heat exchange module includes the condenser of the air conditioning system and the radiator of the engine. In this module, the condenser and radiator share a single fan for cooling. Because the fan resources are shared by the radiator, the airflow allocated to the condenser is insufficient, and the fan cannot be precisely controlled to meet the condenser's cooling needs, thus affecting the air conditioning's cooling effect, resulting in long cooling times and poor performance. To address this issue, related technologies could develop larger condensers to improve heat dissipation capacity and thus enhance the air conditioning's cooling effect. However, larger condensers suffer from higher costs, greater weight, and require more space in the vehicle layout.

[0018] Under special operating conditions such as prolonged idling or climbing hills, the vehicle engine experiences a high load and generates a significant amount of heat. When the engine coolant temperature becomes too high, in order to protect the engine, the vehicle's temperature control system will prioritize cooling the radiator, allocating more fan airflow to the radiator, and may even temporarily shut down the air conditioning system, causing the air conditioning to stop cooling.

[0019] In addition, the condenser in the front-end heat exchange module is usually located in front of the radiator. Air flows through the condenser first, increasing airflow resistance and reducing the airflow to the radiator. This increases the radiator's intake air resistance, preventing it from receiving sufficient airflow for heat dissipation, resulting in low radiator cooling efficiency. Simultaneously, the heat released during the condenser's cooling process also affects the radiator's cooling efficiency.

[0020] (3) The front-end heat exchange module includes at least one heat exchanger, such as a radiator or fan. The front-end heat exchange module is typically located at the front of the vehicle's engine compartment. These heat exchangers are stacked on top of each other to form a multi-layered structure, for example, four layers. A certain gap must be maintained between each component, resulting in the front-end heat exchange module with multiple heat exchangers occupying a large space when arranged along the front-rear direction of the vehicle's engine compartment. Furthermore, the compact design of the front of the vehicle's engine compartment leads to insufficient space for the front-end heat exchange module.

[0021] (4) The front-end heat exchange module includes a water-cooled intercooler. A water-cooled intercooler is a device used to reduce the temperature of the air entering the engine. If the air temperature at the outlet of the water-cooled intercooler is too low, moisture in the air will condense into water. This condensate may enter the engine and cause it to stall. To address this problem, related technologies can tilt the water-cooled intercooler, for example, by setting the inlet of the water-cooled intercooler higher than the outlet. When the condensate flows to the outlet, it will evaporate quickly, thus preventing some condensate from entering the engine. However, this does not completely eliminate the possibility of condensate entering the engine.

[0022] This application provides a vehicle heat exchange module, applied to a vehicle. The vehicle heat exchange module includes at least one of the following: a gas-cooled radiator 5, a first water pump 6, a valve 7, a gas cooling device 8, an exhaust gas recirculation system 9, and a cooling medium. The gas-cooled radiator 5 is connected to the first water pump 6; the first water pump 6 is connected to the valve 7; the valve 7 includes a first outlet and a second outlet; the first outlet is connected to the gas cooling device 8; the gas cooling device 8 is connected to the exhaust gas recirculation system 9; the second outlet is connected to the exhaust gas recirculation system 9; the exhaust gas recirculation system 9 is connected to the gas-cooled radiator 5; the gas cooling device 8 is equipped with... The device is placed around the engine 22 of the vehicle. When valve 7 is in the state of first outlet closed and second outlet open, the cooling medium flows from the first water pump 6 to valve 7, from valve 7 to exhaust gas recirculation system 9, from exhaust gas recirculation system 9 to gas cooling radiator 5, and from gas cooling radiator 5 to the first water pump 6, so that the cooling medium no longer flows through the gas cooling device 8, thereby controlling the temperature of the gas cooling device 8 and preventing the temperature of the gas cooling device 8 from being too low, which would cause condensation of the air around the gas cooling device 8 to enter the engine 22 and cause the engine 22 to stall.

[0023] This application provides a vehicle heat exchange module; please refer to [reference needed]. Figure 1 This system is applied to vehicles. The vehicle heat exchange module includes at least one of the following: a gas-cooled radiator 5, a first water pump 6, a valve 7, a gas cooling device 8, an exhaust gas recirculation system 9, and a cooling medium. The gas-cooled radiator 5 is connected to the first water pump 6. The first water pump 6 is connected to the valve 7. The valve 7 includes a first outlet and a second outlet. The first outlet is connected to the gas cooling device 8. The gas cooling device 8 is connected to the exhaust gas recirculation system 9. The second outlet is connected to the exhaust gas recirculation system 9. The exhaust gas recirculation system 9 is connected to the gas-cooled radiator 5. The gas cooling device 8 is disposed around the engine 22 of the vehicle.

[0024] When the valve 7 is in the position of the first outlet closed and the second outlet open, the cooling medium flows from the first water pump 6 to the valve 7, from the valve 7 to the exhaust gas recirculation system 9, from the exhaust gas recirculation system 9 to the gas cooling radiator 5, and from the gas cooling radiator 5 to the first water pump 6.

[0025] In this embodiment, the vehicle heat exchange module is located at the front of the vehicle's engine compartment; this module can also be referred to as the front-end heat exchange module. The vehicle heat exchange module includes at least one of the following: a gas-cooled radiator 5, a first water pump 6, a valve 7, a gas cooling device 8, an EGR (Exhaust Gas Recirculation) system, and a cooling medium. The first water pump 6, together with the gas-cooled radiator 5, the valve 7, the gas cooling device 8, and the exhaust gas recirculation system 9, constitutes a gas cooling circuit. The gas cooling device 8 can be a water-cooled intercooler. The gas cooling circuit can also be referred to as a cryogenic circuit.

[0026] In this embodiment, the gas cooling circuit is used to cool the gas entering the vehicle engine 22. The gas cooling radiator 5 is connected to the first water pump 6; the first water pump 6 is connected to the valve 7.

[0027] Valve 7 includes a first outlet and a second outlet. Figure 1 The serial number B on valve 7 refers to the second outlet of valve 7, and the serial number C refers to the first outlet of valve 7. The first outlet is connected to the gas cooling device 8; the gas cooling device 8 is connected to the exhaust gas recirculation system 9; the second outlet is connected to the exhaust gas recirculation system 9; and the exhaust gas recirculation system 9 is connected to the gas cooling radiator 5. The first water pump 6 in the gas cooling circuit can drive the cooling medium in the gas cooling circuit to flow in the gas cooling circuit.

[0028] The cooling medium can flow from the first water pump 6 to valve 7, from valve 7 to gas cooling equipment 8, from gas cooling equipment 8 to exhaust gas recirculation system 9, from exhaust gas recirculation system 9 to gas cooling radiator 5, and then from gas cooling radiator 5 back to the first water pump 6. With the adjustment of valve 7, the cooling medium can no longer flow through gas cooling equipment 8 and can flow directly from valve 7 to exhaust gas recirculation system 9.

[0029] In this embodiment, the gas cooling device 8 in the gas cooling circuit is disposed around the engine 22 of the vehicle. When the gas to be introduced into the engine 22 passes through the gas cooling device 8, the gas cooling device 8 can absorb the heat in the gas to be introduced into the engine 22 using the cooling medium flowing through the gas cooling device 8, thereby cooling the gas to be introduced into the engine 22. After absorbing the heat in the gas to be introduced into the engine 22, the cooling medium flows to the gas cooling radiator 5, where the gas cooling radiator 5 can release the heat absorbed by the cooling medium.

[0030] In this embodiment, when the gas cooling device 8 cools the gas to be introduced into the engine 22, the cooling medium flowing through the gas cooling device 8 lowers its temperature. If the temperature of the gas cooling device 8 is too low, moisture in the air surrounding the gas cooling device 8 may condense into water, which could enter the engine 22 and cause it to stall. In this embodiment, when the temperature of the gas cooling device 8 is not greater than a preset condensation temperature threshold, moisture in the air surrounding the gas cooling device 8 will condense into water. In this case, valve 7 is in the state of first outlet closed and second outlet open. The cooling medium flows from the first water pump 6 to valve 7, from valve 7 to exhaust gas recirculation system 9, from exhaust gas recirculation system 9 to gas cooling radiator 5, and from gas cooling radiator 5 to first water pump 6, so that the cooling medium in the gas cooling circuit no longer flows through the gas cooling device 8, but flows directly from valve 7 to exhaust gas recirculation system 9.

[0031] In this embodiment, the vehicle heat exchange module includes at least one of the following: a gas-cooled radiator 5, a first water pump 6, a valve 7, a gas cooling device 8, an exhaust gas recirculation system 9, and a cooling medium; the gas-cooled radiator 5 is connected to the first water pump 6; the first water pump 6 is connected to the valve 7; the valve 7 includes a first outlet and a second outlet; the first outlet is connected to the gas cooling device 8; the gas cooling device 8 is connected to the exhaust gas recirculation system 9; the second outlet is connected to the exhaust gas recirculation system 9; the exhaust gas recirculation system 9 is connected to the gas-cooled radiator 5; the gas cooling device 8 is installed in the vehicle's engine compartment. Around the engine 22; with valve 7 in the first outlet closed and the second outlet open, the cooling medium flows from the first water pump 6 to valve 7, from valve 7 to exhaust gas recirculation system 9, from exhaust gas recirculation system 9 to gas cooling radiator 5, and from gas cooling radiator 5 to the first water pump 6, so that the cooling medium no longer flows through the gas cooling device 8, thereby controlling the temperature of the gas cooling device 8 and preventing the temperature of the gas cooling device 8 from being too low, causing condensation of the air around the gas cooling device 8 to enter the engine 22 and cause the engine 22 to stall.

[0032] In some embodiments of this application, when the valve 7 is in the state of the first outlet open and the second outlet closed, the cooling medium flows from the first water pump 6 to the valve 7, from the valve 7 to the gas cooling device 8, from the gas cooling device 8 to the exhaust gas recirculation system 9, from the exhaust gas recirculation system 9 to the gas cooling radiator 5, and from the gas cooling radiator 5 to the first water pump 6.

[0033] In this embodiment, the temperature of the gas cooling device 8 will rise when the cooling medium in the gas cooling circuit no longer flows through it or under other circumstances. If the temperature of the gas cooling device 8 exceeds a preset gas cooling temperature threshold, the gas cooling device 8 needs to be cooled to cool the gas entering the engine 22. In this case, valve 7 is in the state of first outlet open and second outlet closed. The cooling medium flows from the first water pump 6 to valve 7, from valve 7 to the gas cooling device 8, from the gas cooling device 8 to the exhaust gas recirculation system 9, from the exhaust gas recirculation system 9 to the gas cooling radiator 5, and from the gas cooling radiator 5 to the first water pump 6, so that the cooling medium in the gas cooling circuit flows through the gas cooling device 8.

[0034] In this embodiment, when the temperature of the gas cooling device 8 is greater than the preset gas cooling temperature threshold, the valve 7 is in the state of opening the first outlet and closing the second outlet, so that the cooling medium in the gas cooling circuit flows through the gas cooling device 8, thereby achieving the cooling treatment of the gas cooling device 8, so that the gas cooling device 8 can continue to cool the gas to be entered into the engine 22.

[0035] In this embodiment, a control unit for controlling the vehicle's heat exchange module may be provided in the vehicle. Valve 7 may be a proportional valve. The proportional valve can control the flow rate of the cooling medium flowing through the gas cooling device 8, thereby controlling the temperature of the gas entering the engine 22 through the gas cooling device 8. The control unit can control the gas cooling device 8 to cool the gas entering the engine 22 using the cooling medium in the gas cooling circuit, and control the gas cooling radiator 5 to release the heat absorbed from the gas by the cooling medium in the gas cooling circuit when cooling the gas entering the engine 22.

[0036] When the control unit controls the gas cooling device 8 to cool the gas entering the engine 22 using a cooling medium, the temperature T of the gas cooling device 8 can be detected. The gas cooling device 8 has a condensation temperature threshold T2 and a gas cooling temperature threshold T1. The condensation temperature threshold T2 is the minimum temperature at which the gas cooling device 8 prevents condensation. When the temperature T of the gas cooling device 8 is not greater than the condensation temperature threshold T2, moisture in the air surrounding the gas cooling device 8 will condense into condensate. The gas cooling temperature threshold T1 is the maximum temperature of the gas cooling device 8. When the temperature T of the gas cooling device 8 is greater than the gas cooling temperature threshold T1, cooling treatment of the gas cooling device 8 is required.

[0037] Therefore, when the control unit detects that the temperature T of the gas cooling device 8 is greater than the gas cooling temperature threshold T1, the control unit can control the first outlet of valve 7 to be fully open and the second outlet to be closed, so that all the cooling medium flowing out of the first water pump 6 passes through the gas cooling device 8. When the control unit detects that the temperature T of the gas cooling device 8 is not greater than the condensation temperature threshold T2, the control unit can control the first outlet of valve 7 to be fully closed and the second outlet to be fully open, so that the cooling medium flowing out of the first water pump 6 does not pass through the gas cooling device 8.

[0038] In this embodiment, the vehicle also includes an air filter 20 and a turbocharger 21. The air filter 20, turbocharger 21, gas cooling device 8, engine 22, and exhaust gas recirculation system 9 constitute an intercooling circuit. When the exhaust gas discharged from the engine 22 passes through the exhaust gas recirculation system 9, the exhaust gas recirculation system 9 uses the cooling medium flowing through the gas cooling circuit to cool the exhaust gas discharged from the engine 22. The air is filtered through the air filter 20 to obtain filtered air. The filtered air and the cooled exhaust gas are mixed to obtain a mixed gas. After the mixed gas is pressurized by the turbocharger 21, it forms a high-temperature gas after compression. This high-temperature gas after compression is the gas to be entered into the engine 22. The gas cooling device 8 can cool the gas to be entered into the engine 22.

[0039] In this embodiment, the valve 7 in the gas cooling circuit includes a first outlet and a second outlet; the first outlet is connected to the gas cooling device 8, and the gas cooling device 8 is connected to the exhaust gas recirculation system 9; the second outlet is connected to the exhaust gas recirculation system 9. This realizes that by setting the valve 7 and a parallel water circuit in front of the gas cooling device 8, the cooling medium in the gas cooling circuit can be controlled to no longer flow through the gas cooling device 8, thereby avoiding the problem that the temperature of the gas cooling device 8 is too low, causing the condensed water formed by the air around the gas cooling device 8 to enter the engine 22 and cause the engine 22 to shut down.

[0040] In some embodiments of this application, the vehicle heat exchange module further includes a temperature sensor 23; the temperature sensor 23 is disposed at the flow outlet of the gas cooling device 8 for the cooling medium.

[0041] In this embodiment, the vehicle heat exchange module includes a temperature sensor 23. The temperature sensor 23 is located at the flow outlet of the cooling medium in the gas cooling circuit of the gas cooling device 8, and can detect the temperature of the gas cooling device 8. Therefore, the control unit can control the temperature sensor 23 to detect the temperature of the gas cooling device 8.

[0042] In this embodiment, the vehicle heat exchange module further includes a temperature sensor 23. The temperature sensor 23 is located at the flow outlet of the gas cooling device 8 for the cooling medium. The temperature sensor 23 can detect the temperature of the gas cooling device 8, determine whether the gas cooling device 8 needs to be cooled, or determine whether the gas cooling device 8 is too cold, causing condensation from the air around the gas cooling device 8 to enter the engine 22.

[0043] In some embodiments of this application, the vehicle heat exchange module further includes at least one of an engine radiator 1, a first fan 2, a condenser 15, and a second fan 16; the first fan 2 is fixed to the engine radiator 1; the second fan 16 is fixed to the condenser 15; and the gas cooling radiator 5 is located around the first fan 2.

[0044] The first fan 2 and the second fan 16 are located in different positions in the vehicle's engine compartment.

[0045] In this embodiment of the application, the vehicle heat exchange module further includes at least one of the following: an engine radiator 1, a first fan 2, a condenser 15, and a second fan 16.

[0046] In this embodiment, the first fan 2 is fixed to the engine radiator 1, which can also be referred to as a high-temperature radiator. The engine radiator 1, the first fan 2, and the engine 22 can constitute an engine cooling system. The second fan 16 is fixed to the condenser 15.

[0047] In this embodiment, the first fan 2 is fixed to the engine radiator 1 and is also located around the gas-cooled radiator 5. The first fan 2 can rotate to bring cool side air to dissipate the heat released by the gas-cooled radiator 5 when cooling the gas entering the engine 22, so that the temperature of the cooling medium in the gas cooling circuit meets the preset temperature requirements.

[0048] In this embodiment, the first fan 2 and the second fan 16 can be located at different positions in the vehicle's engine compartment. The first fan 2 can be located at the front of the vehicle's engine compartment, and the second fan 16 can be located at the side headlights. Since the first fan 2 is fixed to the engine radiator 1 and the second fan 16 is fixed to the condenser 15, the engine radiator 1 is located at the front of the vehicle's engine compartment, and the condenser 15 is located at the side headlights. Since the gas-cooled radiator 5 is located around the first fan 2, the gas-cooled radiator 5 is located at the front of the vehicle's engine compartment.

[0049] In this embodiment, the vehicle heat exchange module further includes an engine radiator 1, a first fan 2, a condenser 15, and a second fan 16. The first fan 2 is fixed to the engine radiator 1; the second fan 16 is fixed to the condenser 15. The first fan 2 is used to dissipate the heat released by the engine radiator 1 during the cooling of the engine 22; the second fan 16 is used to dissipate the heat released by the condenser 15 during the vehicle's air conditioning cooling process. By controlling the condenser 15 separately with the second fan 16, the second fan 16 can precisely control the cooling demand of the condenser 15, enabling rapid dissipation of the heat released by the condenser 15, improving the air conditioning cooling effect, and shortening the cooling time. This also solves the problem that when the engine radiator 1 and the condenser 15 share a single fan for heat dissipation, under special operating conditions such as prolonged vehicle idling or hill climbing, the vehicle's engine load is high, generating a lot of heat. To protect the engine, the vehicle's temperature control system will prioritize the heat dissipation of the engine radiator 1, allocating more fan airflow to the engine radiator 1, or even temporarily shutting down the air conditioning system, resulting in interruption of air conditioning cooling. In addition, there is no need to develop a larger condenser 15 to improve heat dissipation and thus enhance the air conditioning cooling effect.

[0050] In this embodiment, the first fan 2 and the second fan 16 are located at different positions in the vehicle engine compartment. Therefore, the condenser 15 and the engine radiator 1 are located at different positions in the vehicle engine compartment. This solves the problem that when the condenser 15 is located in front of the engine radiator 1, the air intake resistance of the engine radiator 1 is increased, making it impossible for the engine radiator 1 to obtain sufficient airflow for heat dissipation, resulting in low heat dissipation efficiency of the engine radiator 1. Furthermore, the heat release during the cooling process of the condenser 15 also affects the heat dissipation efficiency of the engine radiator 1.

[0051] In some embodiments of this application, the engine radiator 1 is connected to the engine 22.

[0052] In this embodiment, the engine radiator 1 is connected to the internal water circuit of the engine 22 via a water pipe, forming a cooling circuit for the engine 22. Because this circuit has a high temperature, it can be referred to as a high-temperature circuit. During vehicle operation, the cooling medium in the high-temperature circuit absorbs heat from the engine 22 as it flows through it. After absorbing heat from the engine 22, the cooling medium flows to the engine radiator 1, where it releases the absorbed heat. The first fan 2 rotates to generate cool side air, dissipating the heat released by the engine radiator 1 during the cooling process of the engine 22. Therefore, the control unit can control the first fan 2 to dissipate the heat released by the engine radiator 1 during the cooling process of the engine 22.

[0053] In this embodiment of the application, the engine cooling system can cool the engine 22 through a high-temperature circuit. The engine radiator 1 exchanges heat with the cooling medium in the high-temperature circuit through the cold side air brought by the first fan 2, so as to cool the engine 22 and make the engine 22 meet the preset temperature requirements.

[0054] In some embodiments of this application, the vehicle heat exchange module further includes at least one of a compressor 19, an evaporator 18, and an expansion valve 17; the condenser 15 is connected to the expansion valve 17; the expansion valve 17 is connected to the evaporator 18; the evaporator 18 is connected to the compressor 19; and the compressor 19 is connected to the condenser 15.

[0055] The vehicle heat exchange module also includes at least one of a compressor 19, an evaporator 18, and an expansion valve 17. The compressor 19, evaporator 18, expansion valve 17, and condenser 15 constitute the vehicle's air conditioning refrigeration circuit. The condenser 15 is connected to the expansion valve 17; the expansion valve 17 is connected to the evaporator 18; the evaporator 18 is connected to the compressor 19; and the compressor 19 is connected to the condenser 15.

[0056] In the air conditioning refrigeration circuit, the refrigerant absorbs heat from the vehicle's interior air at the evaporator 18, evaporating into a gaseous refrigerant. This gaseous refrigerant flows to the compressor 19, which compresses it into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant is then transferred to the condenser 15, where it releases heat, gradually cooling and condensing into a medium-temperature, medium-pressure liquid refrigerant. This medium-temperature, high-pressure liquid refrigerant then flows through the expansion valve 17, transforming into a low-temperature, low-pressure liquid refrigerant before entering the evaporator 18.

[0057] The second fan 16 can rotate to bring cool side air to dissipate the heat released by the condenser 15 during the vehicle's air conditioning cooling process. Therefore, the control unit can control the second fan 16 to dissipate the heat released by the condenser 15 during the vehicle's air conditioning cooling process.

[0058] In some embodiments of this application, the vehicle heat exchange module further includes: a second water pump 10, at least one electrical device, and an electrical device radiator 3; the second water pump 10 is connected to the electrical device; the electrical device is connected to the electrical device radiator 3; the electrical device radiator 3 is connected to the second water pump 10; the electrical device radiator 3 is disposed around the first fan 2.

[0059] In this embodiment, the vehicle heat exchange module includes a second water pump 10, at least one electrical device, and an electrical device radiator 3. The electrical device radiator 3 is also referred to as a low-temperature radiator. The electrical device radiator 3 is disposed around the first fan 2, and therefore can be positioned directly in front of the vehicle's engine compartment. The second water pump 10 is connected to the electrical device; the electrical device is connected to the electrical device radiator 3; and the electrical device radiator 3 is connected to the second water pump 10.

[0060] In the embodiments of this application, at least one electrical device may include a motor 11, an electronic control unit 12, a multi-function device 13, and a range extender 14. The motor 11, also known as an electric drive, refers to an electric motor. The electronic control unit 12 refers to a power electronic controller, and the multi-function device is a multi-in-one system integrating multiple power electronic components (such as DC-DC converters, chargers, etc.).

[0061] At least one of the second water pump 10, at least one electrical device, and at least one electrical device radiator 3 can constitute an electrical device cooling circuit. The second water pump 10 can drive the cooling medium in the electrical device cooling circuit to flow from the second water pump 10 to at least one electrical device, and then from at least one electrical device to the electrical device radiator 3. When the cooling medium flows to the electrical device, it can absorb heat from the electrical device. When the cooled medium, after absorbing heat, flows to the electrical device radiator 3, it can release the heat absorbed by the cooling medium.

[0062] The first fan 2 can rotate to generate cool side air to dissipate the heat released by the electrical equipment radiator 3 during the process of cooling the electrical equipment using the electrical equipment cooling circuit, so that the temperature of the cooling medium in the electrical equipment cooling circuit meets the preset temperature requirements. Therefore, the control unit can control the first fan 2 to dissipate the heat released by the electrical equipment radiator 3 during the process of cooling the electrical equipment using the electrical equipment cooling circuit.

[0063] In this embodiment, the radiator in the vehicle heat exchange module includes an engine radiator 1, a gas cooling radiator 5, and an electrical equipment radiator 3. Addressing the issue that increasingly smaller, even closed, grilles (openings) on the front of the vehicle lead to poor wind-side constraints for the engine radiator 1, gas cooling radiator 5, and electrical equipment radiator 3, the condenser 15 is positioned near the headlights on the side of the vehicle without changing the fan power or radiator core size. This reduces the wind resistance of the engine radiator 1, gas cooling radiator 5, and electrical equipment radiator 3, improving wind-side performance.

[0064] In this embodiment, the first fan 2 is fixed to the engine radiator 1 and is located around the gas-cooled radiator 5 and the electrical equipment radiator 3. The second fan 16 is fixed to the condenser 15. The engine radiator 1, the first fan 2, the gas-cooled radiator 5, and the electrical equipment radiator 3 are located at the front of the vehicle's engine compartment, and the condenser 15 is located at the front headlights of the vehicle. (Refer to...) Figure 1 The gas-cooled radiator 5 is located at the very front of the vehicle, followed by the electrical equipment radiator 3, engine radiator 1, and first fan 2 stacked in sequence. The condenser 15 and second fan 16 are located near the side headlights, with the condenser 15 in front and the second fan 16 behind.

[0065] The engine radiator 1, first fan 2, gas cooling radiator 5, and electrical equipment radiator 3 at the front of the vehicle's engine compartment have a three-layer structure. Compared with related technologies, where the condenser 15 is located in front of the radiator, resulting in a four-layer structure at the front of the vehicle's engine compartment, the staggered arrangement of the condenser 15 and the radiator solves the problem of the front heat exchange module with four heat exchangers occupying a large space when arranged along the front-rear direction of the vehicle's engine compartment, and the problem of insufficient front heat exchange module due to the compactness of the front of the vehicle's engine compartment.

[0066] In this embodiment, the vehicle heat exchange module refers to a heat exchange component at the front of the vehicle, including an engine radiator 1, an electrical equipment radiator 3, a gas cooling radiator 5, a condenser 15, a first fan 2, and a second fan 16. The engine radiator 1, electrical equipment radiator 3, gas cooling radiator 5, and first fan 2 are arranged opposite each other at the front of the vehicle, with the first fan 2 dissipating heat from the engine radiator 1, electrical equipment radiator 3, and gas cooling radiator 5. The condenser 15 and second fan 16 are arranged opposite each other near the front side headlights, with the second fan 16 dissipating heat from the condenser 15. The second fan 16 is offset from the engine radiator 1, electrical equipment radiator 3, and gas cooling radiator 5, reducing wind resistance caused by the condenser 15 stacked on top of the radiator and improving the radiator's heat dissipation efficiency.

[0067] In some embodiments of this application, the vehicle heat exchange module further includes: an expansion tank 4; the expansion tank 4 is used to adjust the liquid level of the cooling medium to be within a target liquid level range and to release the gas corresponding to the cooling medium; the gas corresponding to the cooling medium is the gas generated by the cooling medium in the vehicle heat exchange module under the action of temperature changes in the vehicle heat exchange module.

[0068] In this embodiment, the vehicle heat exchange module further includes an expansion tank 4. The expansion tank 4 is used for water replenishment and gas release. The expansion tank 4 can adjust the liquid level of the cooling medium in the vehicle heat exchange module to a target liquid level range and release the gas corresponding to the cooling medium. The gas corresponding to the cooling medium is the gas generated by the cooling medium in the vehicle heat exchange module under the influence of temperature changes in the vehicle heat exchange module, such as gas that may be generated due to temperature increases in the cooling medium. For example, the expansion tank 4 can replenish water and release the gas corresponding to the cooling medium in the electrical equipment cooling circuit, high-temperature circuit, and gas cooling circuit.

[0069] In this embodiment, the expansion tank 4 can adjust the liquid level of the cooling medium in the vehicle heat exchange module to be within the target liquid level range and release the gas corresponding to the cooling medium. The gas corresponding to the cooling medium is the gas generated by the cooling medium in the vehicle heat exchange module under the action of temperature change in the vehicle heat exchange module, so that the vehicle heat exchange module can operate normally and smoothly dissipate heat from the equipment inside the vehicle.

[0070] This application also provides a vehicle temperature control system, including the vehicle heat exchange module as described in any of the preceding claims.
