[0039] In the related art, the thermal management system of a vehicle generally uses a heat exchange system for multiple components (such as air conditioners, batteries, car refrigerators, etc.). However, in actual use, some components (such as air conditioners and batteries) have both cooling and heating requirements, while other components (such as car refrigerators) have always been used at low temperatures for refrigeration and freezing. In this way, when the heat exchange system is running, the components with low-temperature requirements will conflict with the components with both cooling and heating requirements, and it cannot be guaranteed that the components with low-temperature requirements can achieve the cooling effect under any conditions.
[0040] The utility model proposes a heat exchange system 100. The heat exchange system 100 enables a first component with two usage requirements of cooling and heating to coordinate with a second component with low-temperature usage requirements in the same heat exchange system 100, and can ensure that the second component achieves a cooling effect regardless of whether the first component is in cooling or heating mode. Taking the application of the heat exchange system 100 to a vehicle as an example, the first component can be an on-board air conditioner (or battery) with two requirements of cooling and heating in the vehicle, and the second component can be an on-board refrigerator 200 with low-temperature usage requirements in the vehicle.
[0041] See also Figure 1 and Figure 2In one embodiment of the utility model, the heat exchange system 100 includes a compressor 10, a first heat exchange component 20, a first flow regulator 31 and a second heat exchange component 40; the compressor 10, the first heat exchange component 20, the first flow regulator 31 and the second heat exchange component 40 are connected to form a refrigerant circulation loop; the heat exchange system 100 also includes a third heat exchange component 50, a second flow regulator 32 and a reversing device 60, the third heat exchange component 50 is connected in series to the flow path between the first flow regulator 31 and the second heat exchange component 40; the second flow regulator 32 is connected in series to the flow path between the second heat exchange component 40 and the third heat exchange component 50; the reversing device 60 is arranged in the refrigerant circulation loop, and is used to switch the refrigerant flow direction in the refrigerant circulation loop.
[0042] Taking the heat exchange system 100 applied to a vehicle as an example, the compressor 10, the first heat exchange component 20, the first flow regulator 31 and the second heat exchange component 40 are connected to form a refrigerant circulation loop, which can be a refrigerant circulation loop of a vehicle air conditioner, and one of the first heat exchange component 20 and the second heat exchange component 40 is used as a condenser component of the vehicle air conditioner, and the other is used as an evaporator component of the vehicle air conditioner. The reversing device 60 controls the flow direction of the refrigerant in the refrigerant circulation loop, and the flow is adjusted in combination with the first flow regulator 31, so that the vehicle air conditioner can achieve a cooling or heating function. The third heat exchange component 50 is connected in series to the flow path between the first flow regulator 31 and the second heat exchange component 40. For example, the third heat exchange component 50 can be used as an evaporator component of a vehicle refrigerator 200 to cool the vehicle refrigerator 200. The second flow regulator 32 is connected in series to the flow path between the second heat exchange component 40 and the third heat exchange component 50, and the refrigerant flow of the flow path can be controlled.
[0043] Among them, the first heat exchange component 20, the second heat exchange component 40 and the third heat exchange component 50 may include a heat exchange body and a fan for dissipating the heat or cold generated by the heat exchange body. The first flow regulator 31 and the second flow regulator 32 include but are not limited to the use of an electronic expansion valve, a thermal expansion valve, a capillary tube or other types of throttling components. The reversing device 60 includes but is not limited to the use of a four-way reversing valve, or a combination of multiple one-way valves and solenoid valves, or other reversing structures that can achieve reversal of the refrigerant, as long as it can control the refrigerant to flow forward or backward in the refrigerant circulation flow path.
[0044] like Figure 1As shown, when the vehicle air conditioner is in the cooling mode, the reversing device 60 controls the refrigerant output from the exhaust port 11 of the compressor 10 to flow along the first heat exchange component 20, the first flow regulating member 31, the third heat exchange component 50, the second flow regulating member 32, and the second heat exchange component 40, and finally flows back to the compressor 10 from the return port 12 of the compressor 10, forming a refrigeration cycle. In this mode, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 10 first enters the first heat exchange component 20 for condensation and heat exchange. The first heat exchange component 20 serves as a condenser component in the entire refrigeration cycle. The first flow regulating member 31 throttles and reduces the pressure of the refrigerant after condensation and heat exchange, and the low-temperature and low-pressure liquid refrigerant then enters the third heat exchange component 50 and the second heat exchange component 40 for evaporation and heat exchange. At this time, the second heat exchange component 40 can be used as the evaporator component of the vehicle air conditioner, and the third heat exchange component 50 can be used as the evaporator component of the vehicle refrigerator 200 to cool the vehicle refrigerator 200, so that the vehicle refrigerator 200 can achieve a refrigeration effect.
[0045] like Figure 2 As shown, when the vehicle air conditioner is in heating mode, the reversing device 60 controls the refrigerant output from the exhaust port 11 of the compressor 10 to flow along the second heat exchange component 40, the second flow regulating component 32, the third heat exchange component 50, the first flow regulating component 31, and the first heat exchange component 20, and finally flows back to the compressor 10 from the return air port 12 of the compressor 10, forming a heating cycle. In this mode, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 10 first enters the second heat exchange component 40 for condensation and heat exchange. The second heat exchange component 40 serves as a condenser component in the entire heating cycle. The second flow regulator 32 throttles and reduces the pressure of the refrigerant after condensation and heat exchange. The low-temperature and low-pressure liquid refrigerant then enters the third heat exchange component 50 and the first heat exchange component 20 for evaporation and heat exchange. At this time, the first heat exchange component 20 can be used as an evaporator component of the vehicle air conditioner, and the third heat exchange component 50 can be used as an evaporator component of the vehicle refrigerator 200 to cool the vehicle refrigerator 200, so that the vehicle refrigerator 200 can achieve a refrigeration effect.
[0046] The technical solution of the utility model forms a refrigerant circulation loop by connecting the compressor 10, the first heat exchange component 20, the first flow regulating component 31, the third heat exchange component 50, the second flow regulating component 32 and the second heat exchange component 40; wherein the first heat exchange component 20 and the second heat exchange component 40 can be used as the condenser component or the evaporator component of the first component (such as the vehicle air conditioner), and the second heat exchange component 40 can be used as the evaporator component of the second component (such as the vehicle refrigerator 200). When in use, the refrigerant flow direction in the refrigerant circulation loop is controlled by the reversing device 60, and the flow is adjusted in combination with the first flow regulating member 31 and the second flow regulating member 32, so that the first component with both cooling and heating requirements and the second component with low-temperature requirements can coordinately operate in the same heat exchange system 100, and ensure that no matter whether the first component (such as a vehicle air conditioner) is in cooling mode or heating mode, the third heat exchange component 50 can serve as the evaporator component of the second component (such as a vehicle refrigerator 200) to cool the second component, thereby achieving a cooling effect for the second component to meet the low-temperature requirements of the second component.
[0047] In one embodiment, the reversing device 60 is a four-way reversing valve that connects the compressor 10 to the first heat exchange component 20 and the second heat exchange component 40 respectively; when the four-way reversing valve is in the first state (such as Figure 1 As shown), the exhaust port 11 of the compressor 10 is connected to the first heat exchange component 20 via the four-way reversing valve, and the return air port 12 of the compressor 10 is connected to the second heat exchange component 40 via the four-way reversing valve; when the four-way reversing valve is in the second state (as shown Figure 2 As shown), the exhaust port 11 of the compressor 10 is connected to the second heat exchange component 40 via the four-way reversing valve, and the return air port 12 of the compressor 10 is connected to the first heat exchange component 20 via the four-way reversing valve.
[0048] In this embodiment, the reversing device 60 adopts a four-way reversing valve, which has a first port 61, a second port 62, a third port 63 and a fourth port 64; the exhaust port 11 of the compressor 10 is connected to the first port 61, the end of the first heat exchange component 20 away from the third heat exchange component 50 is connected to the second port 62, the end of the second heat exchange component 40 away from the third heat exchange component 50 is connected to the third port 63, and the return air port 12 of the compressor 10 is connected to the fourth port 64. Figure 1As shown, when the vehicle air conditioner is in cooling mode, the reversing device 60 is in the first state. At this time, the first port 61 is connected to the second port 62, and the third port 63 is connected to the fourth port 64, so that the refrigerant output from the exhaust port 11 of the compressor 10 flows along the first heat exchange component 20, the first flow regulator 31, the third heat exchange component 50, the second flow regulator 32, and the second heat exchange component 40, and finally flows back to the compressor 10 from the return air port 12 of the compressor 10, forming a refrigeration cycle. Figure 2 As shown, when the vehicle air conditioner is in the heating mode, the reversing device 60 is in the second state, at which the first port 61 is connected to the third port 63, and the second port 62 is connected to the fourth port 64, so that the refrigerant output from the exhaust port 11 of the compressor 10 flows along the second heat exchange component 40, the second flow regulating member 32, the third heat exchange component 50, the first flow regulating member 31, and the first heat exchange component 20, and finally flows back to the compressor 10 from the return air port 12 of the compressor 10, forming a heating cycle. The use of a four-way reversing valve for refrigerant reversing has the advantages of convenient operation, compact structure, long service life, high efficiency and energy saving, and high flexibility, which is conducive to improving the overall performance and operation efficiency of the system.
[0049] like Figure 1 As shown, in one embodiment, the heat exchange system 100 also includes a third flow regulating component 33 and a fourth flow regulating component 34, the refrigerant circulation loop includes a first branch 101 and a second branch 102 connected in parallel between the first flow regulating component 31 and the second flow regulating component 32, the third heat exchange component 50 and the third flow regulating component 33 are connected in series to the first branch 101, and the fourth flow regulating component 34 is connected in series to the second branch 102.
[0050] In this embodiment, by setting the third flow regulating member 33 and the fourth flow regulating member 34, the refrigerant output by the first flow regulating member 31 or the second flow regulating member 32 can be more reasonably distributed to the first branch 101 and the second branch 102 to meet different usage scenarios. For example, in the vehicle air conditioning cooling (or heating) mode, and in the scenario where the vehicle refrigerator 200 needs to be cooled by the third heat exchange component 50, the first branch 101 is opened by the third flow regulating member 33, and the second branch 102 is closed by the fourth flow regulating member 34. At this time, the refrigerant output by the first flow regulating member 31 (or the second flow regulating member 32) can all flow through the third heat exchange component 50 on the first branch 101 and then flow to the downstream heat exchange component, so that the third heat exchange component 50 has sufficient refrigerant heat exchange, so that the vehicle refrigerator 200 achieves a better cooling effect. For another example, in the cooling mode of the vehicle air conditioner, and in the scenario where the vehicle refrigerator 200 is not needed, the first branch 101 can be closed by the third flow regulating component 33, and the second branch 102 can be opened by the fourth flow regulating component 34, so that the refrigerant output by the first flow regulating component 31 can be fully delivered to the second heat exchange component 40 via the second branch 102, so that the second heat exchange component 40 has sufficient refrigerant heat exchange, so that the vehicle air conditioner can achieve a better cooling effect. For another example, in the heating mode of the vehicle air conditioner, and in the scenario where the vehicle refrigerator 200 is not needed, the first branch 101 can be closed by the third flow regulating component 33, and the second branch 102 can be opened by the fourth flow regulating component 34, so that the refrigerant output by the second flow regulating component 32 can be fully delivered to the first heat exchange component 20 via the second branch 102, so that the first heat exchange component 20 has sufficient refrigerant heat exchange, so that the vehicle air conditioner can achieve a better heating effect.
[0051] Among them, the third flow regulating member 33 can be arranged on the side of the third heat exchange component 50 close to the first flow regulating member 31, or the third flow regulating member 33 can be arranged on the side of the third heat exchange component 50 close to the second flow regulating member 32. Optionally, the third flow regulating member 33 is located between the first flow regulating member 31 and the third heat exchange component 50. The third flow regulating member 33 and the fourth flow regulating member 34 include but are not limited to the use of flow regulating valves, stop valves, etc. The flow regulating valve can not only realize the conduction and shutoff of the flow path, but also adjust the flow rate of the flow path. The stop valve can realize the conduction and shutoff of the flow path. Optionally, the third flow regulating member 33 and / or the fourth flow regulating member 34 adopt a stop valve, which has a simpler structure and can reduce costs.
[0052] Based on the above embodiments, Figure 1As shown, in one embodiment, the heat exchange system 100 further includes a fourth heat exchange component 70 , and the fourth heat exchange component 70 is connected in series on the flow path between the third heat exchange component 50 and the compressor 10 .
[0053] In this embodiment, the fourth heat exchange component 70 can be used for heat exchange of other functional components. For example, when applied to a vehicle, the fourth heat exchange component 70 can be used as a heat exchange component for heat exchange with a battery to achieve cooling or heating functions for the battery. The fourth heat exchange component 70 can be connected to the refrigerant circulation loop in parallel or in series with the second heat exchange component 40, so that the fourth heat exchange component 70 can share a compressor 10 with the first heat exchange component 20, the second heat exchange component 40 and the third heat exchange component 50, which is conducive to reducing costs and reducing the volume of the entire heat exchange system 100.
[0054] like Figure 1 As shown, in one embodiment, the refrigerant circulation loop includes a third branch 103 and a fourth branch 104 connected in parallel between the third heat exchange component 50 and the compressor 10, the second flow regulating element 32 and the second heat exchange component 40 are connected in series to the third branch 103, and the fourth heat exchange component 70 is connected in series to the fourth branch 104.
[0055] In this embodiment, the fourth heat exchange assembly 70 and the second heat exchange assembly 40 are arranged in parallel, so that the fourth heat exchange assembly 70 and the second heat exchange assembly 40 can operate independently. For example, when the second heat exchange assembly 40 is not needed, the third branch 103 can be shut off by the second flow regulator 32, and the refrigerant in the refrigerant circulation loop can still flow through the fourth branch 104 to enter the fourth heat exchange assembly 70 for heat exchange. In this way, the control of the entire heat exchange system 100 is more flexible.
[0056] Furthermore, if Figure 1 As shown, in one embodiment, the heat exchange system 100 further includes a fifth flow regulating component 35 connected in series to the fourth branch 104 , and the fifth flow regulating component 35 is located between the fourth heat exchange component 70 and the third heat exchange component 50 .
[0057] In this embodiment, the refrigerant flow of the fourth branch 104 can be adjusted by the fifth flow regulator 35. The fifth flow regulator 35 is located between the fourth heat exchange component 70 and the third heat exchange component 50. When the refrigerant output by the compressor 10 first passes through the fourth heat exchange component 70 for condensation and heat exchange, it can be throttled and depressurized by the fifth flow regulator 35, and then flows into the third heat exchange component 50 and the first heat exchange component 20 downstream thereof, so that the third heat exchange component 50 and the first heat exchange component 20 can be used as an evaporator to cool the surrounding environment. The fifth flow regulator 35 includes but is not limited to the use of an electronic expansion valve, a thermal expansion valve, a capillary tube or other types of throttling components.
[0058] like Figure 1 As shown, in one embodiment, the heat exchange system 100 further includes a temperature detection element 80 , and the temperature detection element 80 is used to detect the temperature of at least one of the second heat exchange component 40 , the third heat exchange component 50 and the fourth heat exchange component 70 .
[0059] In this embodiment, the temperature detection element 80 includes but is not limited to temperature detection by using a temperature sensing package, a thermocouple, etc. The temperature detection element 80 and each flow regulating component are electrically connected to the control device respectively. When the heat exchange system 100 is in operation, the temperature detection of the corresponding heat exchange component is realized by the temperature detection element 80. The control device can control each flow regulating component in the heat exchange system 100 in a targeted manner according to the temperature detection signal fed back by the temperature detection element 80, thereby realizing the control of the refrigerant flow through the corresponding heat exchange component to achieve a better heat exchange effect. Optionally, the branch where the second heat exchange component 40, the third heat exchange component 50 and the fourth heat exchange component 70 are located are respectively provided with temperature detection elements 80.
[0060] like Figure 1As shown, in one embodiment, the heat exchange system 100 further includes a fourth heat exchange component 70, a third flow regulating member 33, a fourth flow regulating member 34 and a fifth flow regulating member 35; the refrigerant circulation loop includes a first branch 101 and a second branch 102 arranged in parallel, and a third branch 103 and a fourth branch 104 arranged in parallel, the first end of the first branch 101 and the second branch 102 are connected to the first flow regulating member 31, and the second end of the first branch 101 and the second branch 102 are connected to the third branch 101. 103 and the first confluence end of the fourth branch 104, the second confluence end of the third branch 103 and the fourth branch 104 is connected to the compressor 10; the third heat exchange component 50 and the third flow regulating component 33 are connected in series to the first branch 101; the fourth flow regulating component 34 is connected in series to the second branch 102; the second flow regulating component 32 and the second heat exchange component 40 are connected in series to the third branch 103; the fifth flow regulating component 35 and the fourth heat exchange component 70 are connected in series to the fourth branch 104.
[0061] In this embodiment, taking the vehicle air conditioner in cooling mode as an example, the refrigerant discharged from the compressor 10 first enters the first heat exchange component 20 for condensation and heat exchange, and then flows through the first branch 101 and the second branch 102 respectively after throttling and reducing the pressure through the first flow regulator 31, and then flows through the third branch 103 and the fourth branch 104 respectively after merging at the output ends of the first branch 101 and the second branch 102, and finally merges and flows back into the compressor 10. When all branches are in the conducting state, the refrigerant output by the first heat exchange component 20 can flow through each heat exchange component downstream thereof (including the first heat exchange component 20, the second heat exchange component 40 and the third heat exchange component 50), so that each heat exchange component can play a heat exchange role. When the second heat exchange assembly 40 is not needed, the third branch 103 can be closed by the second flow regulator 32; when the third heat exchange assembly 50 is not needed, the first branch 101 can be closed by the third flow regulator 33; when the fourth heat exchange assembly 70 is not needed, the fourth branch 104 can be closed by the fourth flow regulator 34. In this way, the second heat exchange assembly 40, the third heat exchange assembly 50, and the fourth heat exchange assembly 70 can be operated independently or simultaneously according to different usage scenarios, making the control of the entire heat exchange system 100 more flexible and better able to meet different usage scenarios.
[0062] The utility model also provides a vehicle, which includes a heat exchange system 100. The specific structure of the heat exchange system 100 refers to the above embodiment. Since the vehicle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the vehicle includes but is not limited to fuel vehicles, pure electric vehicles, hybrid vehicles, etc., which are not specifically limited here.
[0063] Please combine Figure 1 and Figure 2 In one embodiment, the vehicle includes a vehicle air conditioner and a vehicle refrigerator 200, one of the first heat exchange component 20 and the second heat exchange component 40 is used as a condenser component of the vehicle air conditioner, and the other is used as an evaporator component of the vehicle air conditioner; the third heat exchange component 50 is used as the evaporator component of the vehicle refrigerator 200, and the vehicle refrigerator 200 also includes a semiconductor refrigeration component 210, and the third heat exchange component 50 performs heat exchange with the hot end of the semiconductor refrigeration component 210.
[0064] In this embodiment, whether the vehicle air conditioner is in cooling mode or heating mode, the vehicle refrigerator 200 can be guaranteed to have a cooling effect. And the vehicle refrigerator 200 also includes a semiconductor refrigeration element 210, wherein the semiconductor refrigeration element 210 can be specifically a semiconductor refrigeration chip. The semiconductor refrigeration chip mainly uses the Peltier effect of the semiconductor. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple respectively, so as to achieve the purpose of refrigeration. The semiconductor refrigeration element 210 has a cold end and a hot end. The cold end of the semiconductor refrigeration element 210 is used to exchange heat with the refrigerator body of the vehicle refrigerator 200, and the third heat exchange component 50 is used to exchange heat with the hot end of the semiconductor refrigeration element 210. Since the semiconductor refrigeration element 210 itself has a refrigeration capacity, and the hot end of the semiconductor refrigeration element 210 is dissipated by the third heat exchange component 50, the cold end of the semiconductor refrigeration element 210 has a lower temperature, thereby meeting the need of the vehicle refrigerator 200 to reach a lower temperature. In addition, different cooling temperatures can be achieved by adjusting the voltage across the semiconductor refrigeration element 210. For example, when the vehicle refrigerator 200 requires a lower temperature, the voltage across the semiconductor refrigeration element 210 can be increased so that the cold end of the semiconductor refrigeration element 210 can obtain a lower temperature.
