[0065] The present application provides a heat exchange system.

[0066] Please refer to Figures 1 to 9 In an embodiment of the present application, the heat exchange system 10 is applied to a vehicle, and the vehicle has a vehicle cabin and a vehicle-mounted refrigerator 20. The vehicle generally includes a vehicle body composed of a roof, a floor, side walls and doors, etc., and the main function is to form a vehicle cabin, thereby providing a passenger space and protection.

[0067] The heat exchange system 10 comprises a compressor 900, an outside heat exchange assembly 100, an air conditioner heat exchange assembly 200, a refrigerator heat exchange assembly 300 and a switching device, the outside heat exchange assembly 100 is used for heat exchange with the outside space of the vehicle cabin; the air conditioner heat exchange assembly 200 is used for heat exchange with the inside space of the vehicle cabin, the compressor 900, the outside heat exchange assembly 100 and the air conditioner heat exchange assembly 200 are communicated with each other to form a refrigerant circulating heat exchange loop; the refrigerator heat exchange assembly 300 is used for heat exchange with the vehicle-mounted refrigerator 20; the refrigerator heat exchange assembly 300 has a relatively independent first refrigerant passage 301 and a second refrigerant passage 302; the switching device is used for switchably connecting the first refrigerant passage 301 and the second refrigerant passage 302 to the refrigerant circulating heat exchange loop, so that the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 can be switched between condensation heat release and evaporation heat absorption.

[0068] The technical scheme of the present application sets the refrigerator heat exchange assembly 300 into two independent refrigerant passages, and the switching device switchably connects the first refrigerant passage 301 and the second refrigerant passage 302 to the refrigerant circulating heat exchange loop, so that the vehicle using the heat exchange system 10 has the refrigeration function and the heating function of the vehicle-mounted refrigerator 20, so that the user can choose to drink hot drinks and eat hot food, or the user can choose to drink cold drinks and ice cold food such as ice cold watermelon during driving. In addition, the inside space of the vehicle cabin also has a refrigeration mode and a heating mode, which can improve the versatility of the heat exchange system 10 and improve the user experience of the vehicle.

[0069] Among them, about the compressor 900, the main role of the compressor 900 is to compress the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant to realize the refrigeration cycle. Its working principle is that the compressor 900 sucks the refrigerant from the suction port through the reciprocating motion or rotary motion in its interior, and discharges it to the exhaust port 901. In this process, the temperature and pressure of the refrigerant will rise to realize the effect of refrigeration or heating.

[0070] About the switching device, the switching device can be composed of a four-way valve and an on-off valve, or a control pipeline composed of a plurality of stop valves or on-off valves, and the control pipeline composed of a plurality of stop valves or on-off valves, as shown in Figure 1 This form of switching device has the advantage of low noise.

[0071] In an exemplary embodiment, please refer to Figure 1The switching device includes a first control valve 610, a second control valve 620, a third control valve 630 and a fourth control valve 640, which are used to control the conduction or isolation of the branch circuit. The first control valve 610, the second control valve 620, the third control valve 630 and the fourth control valve 640 can be ordinary on-off valves, or stop valves, or proportional valves, etc. In this embodiment, the four control valves are preferably ordinary on-off valves, which not only can save costs, but also can reduce noise, and in addition, the structure of the ordinary on-off valve is simpler than the other two, which can further simplify the structure of the heat exchange system 10.

[0072] Exemplarily, the structure of the on-off valve includes a valve body, a valve cover, a control rod, a core shaft and a sealing structure, wherein the valve body includes a first chamber and a second chamber, the first chamber is provided with an inlet port and a first guide port, and the second chamber is provided with an outlet port and a second guide port. The inlet port is adapted to be connected with the external pipeline, and the outlet port is in communication with the external pipeline. The valve cover is provided with a switch part at one end, which is arranged towards the valve body, and a pressure regulating part at the other end, which is adapted to receive external force. The switch part has a closed state under the action of external force, moving towards the valve body and blocking the communication between the first guide port and the second guide port, and an open state under the action of the pressure in the first chamber, moving away from the valve body and connecting the first guide port and the second guide port. The control rod includes a rod segment and a blocking segment, the blocking segment is located in the transition hole, and the rod segment extends out of the piston rod through the control rod hole. The length of the core shaft is longer than the length of the core shaft sleeve, the lower end of the core shaft is provided with a lower blocking ring, and the upper end of the core shaft passes through the lower blocking block sealing ring, the core shaft sleeve and the core shaft hole to contact the blocking ring. The sealing structure includes a sealing ring and a sealing ring hole, which is used to prevent fluid leakage. These parts work together to enable the on-off valve to control the on-off of the fluid.

[0073] It can be understood that the above embodiment is only one of the exemplary embodiments of the on-off valve.

[0074] Specifically, the first control valve 610 is connected in series between the exhaust port 901 of the compressor 900 and the outside heat exchange assembly 100, and is used to control the conduction or isolation of the flow path between the exhaust port 901 of the compressor 900 and the outside heat exchange assembly 100.

[0075] The second control valve 620 is connected in series between the first control valve 610 and the outside heat exchange assembly 100, and is used to control the conduction or isolation of the flow path between the first control valve 610 and the outside heat exchange assembly 100.

[0076] The third control valve 630 is connected in series in a flow path between the exhaust port 901 of the compressor 900 and the condenser 210, and is used to control the conduction or blockage of the flow path between the exhaust port 901 of the compressor 900 and the condenser 210.

[0077] The fourth control valve 640 is connected in series in a flow path between the return port 902 of the compressor 900 and the outside heat exchange assembly 100, and is used to control the conduction or blockage of the flow path between the return port 902 of the compressor 900 and the outside heat exchange assembly 100.

[0078] Exemplarily, when both the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 are simultaneously condensing and releasing heat, or when both the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 are simultaneously evaporating and absorbing heat, the first refrigerant passage 301 is connected to the refrigerant circulation heat exchange loop; when one of the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 is condensing and releasing heat, and the other is evaporating and absorbing heat, the second refrigerant passage 302 is connected to the refrigerant circulation heat exchange loop.

[0079] In other embodiments, when both the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 are simultaneously condensing and releasing heat, or when both the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 are simultaneously evaporating and absorbing heat, the second refrigerant passage 302 is connected to the refrigerant circulation heat exchange loop; when one of the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 is condensing and releasing heat, and the other is evaporating and absorbing heat, the first refrigerant passage 301 is connected to the refrigerant circulation heat exchange loop.

[0080] The first refrigerant passage 301 and the second refrigerant passage 302 can be connected in parallel to the refrigerant circulation heat exchange loop, or can be connected in series to the refrigerant circulation heat exchange loop, or the first refrigerant passage 301 can be connected in series to the refrigerant circulation heat exchange loop and the second refrigerant passage 302 can be connected in parallel to the refrigerant circulation heat exchange loop, or the first refrigerant passage 301 can be connected in parallel to the refrigerant circulation heat exchange loop and the second refrigerant passage 302 can be connected in series to the refrigerant circulation heat exchange loop.

[0081] It should be understood that the connection of the first refrigerant passage 301 and the second refrigerant passage 302 to the refrigerant circulation heat exchange loop in series or in parallel is relative to the air conditioner heat exchange assembly 200.

[0082] In an exemplary embodiment, please refer to Figures 1 to 7, the air conditioner heat exchange assembly 200 includes an evaporator 220 and a condenser 210, one of the evaporator 220 and the condenser 210 is connected to the refrigerant circulation heat exchange loop; by dividing the air conditioner heat exchange assembly 200 into independent condenser 210 and evaporator 220, the system can be better controlled by the ordinary on-off valve to switch different flow paths to realize different mode switching. Using ordinary on-off valve to control the system to switch different flow paths can reduce the noise generated by the switching device. The refrigerant flow in the heat exchange system 10 when the evaporator 220 and the condenser 210 are connected to the refrigerant circulation loop respectively, and the refrigerator 20 is in different states.

[0084] If at this time, the target operation mode of the vehicle-mounted refrigerator 20 is also the refrigeration mode, the exhaust port 901 of the compressor 900, the outer heat exchange assembly 100, the first refrigerant passage 301 and the gas inlet port 902 of the compressor 900 are sequentially communicated, please refer to Figure 3 At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange assembly 300 is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, sequentially flows through the outer heat exchange assembly 100 and the first refrigerant passage 301, and then flows back to the gas inlet port 902 of the compressor 900.

[0085] If at this time, the target operation mode of the vehicle-mounted refrigerator 20 is the heating mode, the exhaust port 901 of the compressor 900, the second refrigerant passage 302, the evaporator 220 and the gas inlet port 902 of the compressor 900 are sequentially communicated; please refer to Figure 4 At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange assembly 300 is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, sequentially flows through the second refrigerant passage 302 and the evaporator 220, and then flows back to the gas inlet port 902 of the compressor 900.

[0087] If at this time, the target operation mode of the vehicle refrigerator 20 is the refrigeration mode, please refer to Figure 6 the exhaust port 901 of the compressor 900, the second refrigerant passage 302, the outer heat exchange assembly 100, and the return port 902 of the compressor 900 are sequentially connected; at this time, the refrigerant flow in the refrigerant circulation loop in which the refrigerator heat exchange assembly 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, sequentially flows through the second refrigerant passage 302 and the outer heat exchange assembly 100, and then returns to the return port 902 of the compressor 900.

[0088] If at this time, the target operation mode of the vehicle refrigerator 20 is the heating mode, please refer to Figure 7 the exhaust port 901 of the compressor 900, the condenser 210, the first refrigerant passage 301, and the return port 902 of the compressor 900 are sequentially connected; at this time, the refrigerant flow in the refrigerant circulation loop in which the refrigerator heat exchange assembly 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, sequentially flows through the condenser 210 and the first refrigerant passage 301, and then returns to the return port 902 of the compressor 900.

[0089] In another embodiment, the air conditioner heat exchange assembly 200 includes an evaporator 220 and a condenser 210, one of which is connected to the refrigerant circulation heat exchange loop; as in the previous embodiment, by dividing the air conditioner heat exchange assembly 200 into independent condenser 210 and evaporator 220, the system can be better controlled by a common on-off valve to switch different flow paths to achieve different mode switching. Using a common on-off valve to control the system to switch different flow paths can reduce the noise generated by the switching device. The refrigerant flow in the heat exchange system 10 when the refrigerator 20 is in different states when the evaporator 220 and the condenser 210 are connected to the refrigerant circulation loop will be described below.

[0090] When the evaporator 220 is connected to the refrigerant circulation heat exchange loop, that is, the operation mode of the vehicle air conditioner is the refrigeration mode, in the embodiment, the evaporator 220 and the first refrigerant passage 301 are connected in series, at this time, the target operation mode of the vehicle refrigerator 20 is also the refrigeration mode, the exhaust port 901 of the compressor 900, the outer heat exchange assembly 100, the first refrigerant passage 301, the evaporator 220 and the gas inlet port 902 of the compressor 900 are sequentially communicated; at this time, the refrigerant flow condition of the refrigerant circulation loop in which the evaporator 220 of the air conditioner heat exchange assembly 200 and the refrigerator heat exchange assembly 300 are located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, sequentially flows through the outer heat exchange assembly 100, the first refrigerant passage 301 and the evaporator 220, and then flows back to the gas inlet port 902 of the compressor 900. In the embodiment, since the space of the vehicle refrigerator 20 is small, the heat exchange required is small, the refrigerant first exchanges heat with the vehicle refrigerator 20 through the refrigerator heat exchange assembly 300, and then exchanges heat with the vehicle cabin interior space through the air conditioner heat exchange assembly 200, which has less influence on the heat exchange of the vehicle cabin interior space. In other embodiments, the refrigerant can first exchange heat with the vehicle cabin interior space through the air conditioner heat exchange assembly 200, and then exchange heat with the vehicle refrigerator 20 through the refrigerator heat exchange assembly 300.

[0092] When the condenser 210 is connected to the refrigerant circulation heat exchange loop, that is, when the operation mode of the vehicle air conditioner is the heating mode, if the target operation mode of the vehicle refrigerator 20 is the heating mode at this time, the exhaust port 901 of the compressor 900, the condenser 210, the first refrigerant passage 301, the outer heat exchange assembly 100, and the return port 902 of the compressor 900 are sequentially connected; the refrigerant flow conditions of the condenser 210 of the air conditioner heat exchange assembly 200 and the first refrigerant passage 301 and the second refrigerant passage 302 of the refrigerator heat exchange assembly 300 in the refrigerant circulation loop are as follows: the refrigerant compressed by the compressor 900 is sequentially discharged from the exhaust port 901 of the compressor 900, flows through the condenser 210, the first refrigerant passage 301, and the outer heat exchange assembly 100, and then returns to the return port 902 of the compressor 900.

[0094] In an embodiment, the heat exchange system 10 comprises a flow regulating assembly, which is usually a throttling device in actual operation. Specifically, the flow regulating assembly has the following main functions in the heat exchange system 10:

[0095] Regulate refrigerant flow: the flow regulating assembly can throttle and depress the high-pressure liquid from the condenser 210 to low-pressure liquid, and at the same time regulate the refrigerant flow entering the evaporator 220, so as to ensure that the refrigerant flow in the heat exchange system 10 is within a reasonable range.

[0096] Reduce the difficulty of heat exchange: for example, in the process of heat exchange, the flow regulating assembly makes the refrigerant liquid flow through a small hole, forming a local contraction, so that the flow rate increases and the static pressure decreases. This pressure difference makes the refrigerant more easily evaporate in the evaporator 220, reduces the difficulty of heat exchange, and improves the efficiency of heat exchange.

[0097] Achieve temperature control: the flow regulating assembly can also be an important part of temperature control. When the system needs a colder temperature, the flow of refrigerant can be reduced through the flow regulating assembly, thereby reducing the evaporation temperature. Conversely, when the system needs a warmer temperature, the flow of refrigerant can be increased through the flow regulating assembly, thereby increasing the evaporation temperature.

[0098] Further, in the present embodiment, the flow regulating assembly includes a first flow regulating valve 510, a second flow regulating valve 520, a third flow regulating valve 530, a third flow regulating valve 530, and a fourth flow regulating valve 540, which are respectively used to regulate the flow of refrigerant in the flow path thereof, so as to achieve the user's on-demand adjustment of the internal temperature of the cabin and the temperature of the vehicle-mounted refrigerator 20.

[0099] The first flow regulating valve 510 is arranged on the flow path between the condenser 210 and the outside heat exchange assembly 100; the second flow regulating valve 520 is arranged on the flow path between the outside heat exchange assembly 100 and the evaporator 220; the third flow regulating valve 530 is arranged on the first refrigerant passage 301, and is connected in series on the flow path between the refrigerator heat exchange assembly 300 and the outside heat exchange assembly 100, and is also connected in series on the flow path between the refrigerator heat exchange assembly 300 and the evaporator 220 or the condenser 210; the fourth flow regulating valve 540 is arranged on the second refrigerant passage 302, and is connected in series on the flow path between the refrigerator heat exchange assembly 300 and the outside heat exchange assembly 100, and is also connected in series on the flow path between the refrigerator heat exchange assembly 300 and the evaporator 220 or the condenser 210.

[0100] Regarding the structure of the first flow regulating valve 510, the second flow regulating valve 520, the third flow regulating valve 530, and the fourth flow regulating valve 540, in an exemplary embodiment, the flow regulating assembly generally includes a regulating cavity and an electronic on-off valve for changing the volume of the regulating cavity. The electronic on-off valve can automatically adjust the opening and closing state according to changes in system pressure, temperature, and other conditions, thereby achieving precise regulation of the flow of refrigerant in the refrigerant circulation heat exchange circuit thereof.

[0101] It can be understood that the flow regulating assembly regulates the refrigerant flow in the refrigerant circulation heat exchange loop by changing the volume of the regulating cavity which is connected in series in the branch. In this way, the refrigerant in the air conditioning heat exchange assembly 200 and the refrigerator heat exchange assembly 300 can always maintain the most suitable refrigerant flow, so that the local refrigerant circulation heat exchange loop of the air conditioning heat exchange assembly 200 and the refrigerator heat exchange assembly 300 can achieve the best refrigerant filling amount, and the refrigerant in the air conditioning heat exchange assembly 200 and the refrigerator heat exchange assembly 300 can always have stable and sufficient heat exchange effect, thereby meeting the heat exchange effect of the vehicle air conditioner and the vehicle refrigerator 20.

[0102] In an embodiment, in order to ensure the heating effect of the refrigerator 20, please refer to Figure 1 and Figure 9 , the refrigerator heat exchange assembly 300 comprises a heat exchange member 310 and a semiconductor refrigeration member 320, the heat exchange member 310 is configured to form the first refrigerant passage 301 and the second refrigerant passage 302, and the semiconductor refrigeration member 320 has a first heat exchange surface and a second heat exchange surface, the first heat exchange surface is used for heat exchange with the vehicle refrigerator 20, and the second heat exchange surface is used for heat exchange with the heat exchange member 310. In this embodiment, the refrigerant heat exchange system 10 of the vehicle refrigerator 20 and the refrigerant heat exchange system 10 of the automobile air conditioner are integrated together, and the heat exchange member 310 and the semiconductor refrigeration member 320 are used for cascade heat exchange, thereby reducing the noise of the heat exchange system 10 and reducing the cost of the heat exchange system 10.

[0103] Based on the above embodiment, please continue to refer to Figure 9 , the heat exchange member 310 comprises a heat conduction plate 311 and a pipeline 312, the pipeline 312 forms the first refrigerant passage 301 and the second refrigerant passage 302, the pipeline 312 is arranged on one side of the heat conduction plate 311, and the side of the heat conduction plate 311 away from the pipeline 312 is attached to the semiconductor refrigeration member 320.

[0104] Regarding the heat exchange member 310, please refer to Figure 9 , the heat exchange member 310 comprises a heat conduction plate 311 and a pipeline 312, the heat conduction plate 311 is provided with mounting positions such as mounting holes 303 for adapting and mounting other components (for example, the semiconductor refrigeration member 320 or the vehicle refrigerator 20), and the pipeline 312 forms a passage for the refrigerant to flow through, the pipeline 312 is arranged on one side of the heat conduction plate 311, and the side of the heat conduction plate away from the pipeline is attached to the semiconductor refrigeration member 320. Preferably, the pipeline 312 is embedded in the heat conduction plate 311, so that the heat exchange efficiency of the heat exchange member 310 can be improved. In addition, the heat conduction plate 311 is usually made of aluminum plate, which has the advantages of high heat exchange efficiency, light weight and low price.

[0105] Further, in order to improve the heat exchange efficiency of the heat exchange component 310, the pipeline 312 is arranged in a plurality of segments in a curved manner, or in a plurality of segments in a meandering curved manner. In this way, the contact area of the heat conducting plate 311 and the refrigerant in the pipeline 312 is increased, thereby improving the heat exchange efficiency of the heat exchange component 310.

[0106] Regarding the semiconductor refrigeration component 320, the semiconductor refrigeration component 320 has a cold side heat exchange surface and a hot side heat exchange surface, and the cold side heat exchange surface and the hot side heat exchange surface of the semiconductor refrigeration component 320 can be switched. When a current passes through a thermocouple pair formed by a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer occurs between the two ends, and heat is transferred from one end to the other end, thereby generating a temperature difference to form cold and hot ends. Therefore, by changing the direction of the current, the cold surface can be changed to the hot surface, and the hot surface can be changed to the cold surface. Specifically, adjustments can be made according to whether the box needs to be refrigerated or heated.

[0107] In an embodiment, referring to Figure 9 , the heat exchange system 10 comprises a fourth heat exchange component 400 for heat exchange with the vehicle-mounted water tank; one end of the fourth heat exchange component 400 is in communication with the return gas port 902 of the compressor 900, and the other end is in communication with the outside heat exchange component 100; or, the fourth heat exchange component 400 and the first refrigerant channel 301 are in communication with each other.

[0108] In this embodiment, the heat exchange components of the vehicle-mounted water tank are integrated with the air conditioning heat exchange system 10 of the vehicle and the heat exchange system 10 of the vehicle-mounted refrigerator 20, so that the heat exchange capacity of the compressor 900 and the heat exchange system 10 can be more efficiently utilized. For example, in a use scenario, such as in spring and autumn, when the vehicle-mounted air conditioner does not need to work, the vehicle-mounted refrigerator 20 runs in a heating mode, at this time, the cold energy released by the vehicle-mounted refrigerator 20 for heating can be used to cool the vehicle-mounted water tank through the refrigerant circulation heat exchange loop of the heat exchange system 10.
