[0022] This invention proposes a heat exchange system.

[0023] Please see Figures 1 to 9 In one embodiment of the present invention, the heat exchange system 10 is applied to a vehicle, the vehicle including a vehicle body, an on-board refrigerator 20 and the heat exchange system 10.

[0024] The vehicle body typically includes a body, which consists of a roof, floor, side walls, and doors. Its main function is to form a cabin, thereby providing passengers with seating space and protection.

[0025] The heat exchange system 10 includes a compressor 900, an outer heat exchange component 100, an air conditioning heat exchange component 200, a refrigerator heat exchange component 300, and a switching device. The outer heat exchange component 100 is used for heat exchange with the external space of the vehicle cabin; the air conditioning heat exchange component 200 is used for heat exchange with the internal space of the vehicle cabin. The compressor 900, the outer heat exchange component 100, and the air conditioning heat exchange component 200 are interconnected to form a refrigerant circulation heat exchange loop; the refrigerator heat exchange component 300 is used for heat exchange with the vehicle refrigerator 20; the refrigerator heat exchange component 300 has a relatively independent first refrigerant channel 301 and a second refrigerant channel 302; the switching device is used to switchably connect the first refrigerant channel 301 and the second refrigerant channel 302 to the refrigerant circulation heat exchange loop, so that the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 can switch between condensing and releasing heat simultaneously, or evaporating and absorbing heat simultaneously, or one condensing and releasing heat while the other evaporates and absorbs heat.

[0026] The technical solution of this invention sets the refrigerator heat exchange component 300 into two independent refrigerant channels, and a switching device allows the first refrigerant channel 301 and the second refrigerant channel 302 to be switchably connected to the refrigerant circulation heat exchange loop. This enables vehicles using this heat exchange system 10 to have both cooling and heating functions in their onboard refrigerator 20. Thus, while driving, users can choose to enjoy hot drinks and food, or they can choose to eat refreshing cold drinks, chilled watermelon, or other chilled foods. Furthermore, the vehicle cabin interior also has both cooling and heating modes, improving the versatility of the heat exchange system 10 and enhancing the user experience.

[0027] Regarding compressor 900, its main function is to compress low-temperature, low-pressure refrigerant into high-temperature, high-pressure refrigerant to achieve a refrigeration cycle. Its working principle is that compressor 900, through its internal reciprocating or rotary motion, draws refrigerant in from the return port 902 and compresses it to discharge through the exhaust port 901. During this process, the temperature and pressure of the refrigerant increase to achieve a cooling or heating effect.

[0028] Regarding the switching device, it can consist of a four-way valve and an on / off valve, or a control pipeline composed of multiple shut-off valves or on / off valves. Specifically, a control pipeline composed of multiple shut-off valves or on / off valves is as follows... Figure 1 As shown, this form of switching device has the advantage of low noise.

[0029] In one exemplary embodiment, please refer to Figure 1 The switching device includes a first control valve 610, a second control valve 620, a third control valve 630, and a fourth control valve 640. These four valves control the opening or closing of their respective branches. The first control valve 610, second control valve 620, third control valve 630, and fourth control valve 640 can be ordinary on / off valves, shut-off valves, proportional valves, etc. In this embodiment, ordinary on / off valves are preferred. This not only saves costs and reduces noise, but also simplifies the structure of the heat exchange system 10 compared to the other two types.

[0030] For example, the structure of the on / off valve includes a valve body, a valve cover, a control rod, a spindle, and a sealing structure. The valve body includes a first chamber and a second chamber. The first chamber has an inlet and a first guide port. The second chamber is separated from the first chamber and has an outlet and a second guide port. The inlet is suitable for connection to an external pipeline, and the outlet is connected to an external pipeline. One end of the valve cover has a switching part facing the valve body, and the other end has a pressure regulating part suitable for receiving external force. The switching part has a closed state where it moves towards the valve body under external force, blocking the connection between the first and second guide ports, and an open state where it moves away from the valve body under internal pressure in the first chamber, connecting the first and second guide ports. The control rod includes a rod segment and a stop segment. The stop segment is located within a transition hole, and the rod segment extends out of the piston rod through a control rod hole. The mandrel is longer than the mandrel sleeve. A lower retaining ring is located at the lower end of the mandrel, and the upper end of the mandrel passes through the lower retaining block sealing ring, the mandrel sleeve, and the mandrel hole to contact the retaining ring. The sealing structure includes a sealing ring and a sealing ring hole to prevent fluid leakage. These parts work together to enable the on / off valve to control the flow of fluid.

[0031] It is understood that the above embodiments are merely one example illustrating the on / off valve.

[0032] Specifically, the first control valve 610 is connected in series in the flow path between the exhaust port 901 of the compressor 900 and the outer heat exchange assembly 100. The first control valve 610 is used to control the opening or closing of the flow path between the exhaust port 901 of the compressor 900 and the outer heat exchange assembly 100.

[0033] The second control valve 620 is connected in series in the flow path between the first control valve 610 and the outer heat exchange assembly 100; the second control valve 620 is used to control the opening or closing of the flow path between the first control valve 610 and the outer heat exchange assembly 100.

[0034] The third control valve 630 is connected in series in the flow path between the exhaust port 901 of the compressor 900 and the condenser 210. The third control valve 630 is used to control the opening or closing of the flow path between the exhaust port 901 of the compressor 900 and the condenser 210.

[0035] The fourth control valve 640 is connected in series in the flow path between the return port 902 of the compressor 900 and the outer heat exchange assembly 100. The fourth control valve 640 is used to control the opening or closing of the flow path between the return port 902 of the compressor 900 and the outer heat exchange assembly 100.

[0036] For example, when both the air conditioner heat exchange component 200 and the refrigerator heat exchange component 300 condense and release heat simultaneously, or when both the air conditioner heat exchange component 200 and the refrigerator heat exchange component 300 evaporate and absorb heat simultaneously, the first refrigerant channel 301 is connected to the refrigerant circulation heat exchange circuit; when one of the air conditioner heat exchange component 200 and the refrigerator heat exchange component 300 condenses and releases heat while the other evaporates and absorbs heat, the second refrigerant channel 302 is connected to the refrigerant circulation heat exchange circuit.

[0037] In other embodiments, when both the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 condense and release heat simultaneously, or when both the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 evaporate and absorb heat simultaneously, the second refrigerant channel 302 is connected to the refrigerant circulation heat exchange circuit; when one of the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 condenses and releases heat while the other evaporates and absorbs heat, the first refrigerant channel 301 is connected to the refrigerant circulation heat exchange circuit.

[0038] The first refrigerant channel 301 and the second refrigerant channel 302 can be connected in parallel to the refrigerant circulation heat exchange loop, or they can be connected in series to the refrigerant circulation heat exchange loop. Alternatively, the first refrigerant channel 301 can be connected in series to the refrigerant circulation heat exchange loop, and the second refrigerant channel 302 can be connected in parallel to the refrigerant circulation heat exchange loop. Or, the first refrigerant channel 301 can be connected in parallel to the refrigerant circulation heat exchange loop, and the second refrigerant channel 302 can be connected in series to the refrigerant circulation heat exchange loop.

[0039] It should be understood that the first refrigerant channel 301 and the second refrigerant channel 302 are connected in series and in parallel to the refrigerant circulation heat exchange circuit, which is relative to the air conditioning heat exchange component 200.

[0040] In one exemplary embodiment, please refer to Figures 1 to 7 The air conditioning heat exchange assembly 200 includes an evaporator 220 and a condenser 210, one of which is connected to the refrigerant circulation heat exchange loop. By dividing the air conditioning heat exchange assembly 200 into independent condensers 210 and evaporators 220, different flow paths can be controlled more effectively using ordinary on / off valves to achieve different mode switching. Using ordinary on / off valves to control the switching of different flow paths can reduce the noise generated by the switching device. The following will describe the refrigerant flow in the heat exchange system 10 when the evaporator 220 and condenser 210 are connected to the refrigerant circulation loop respectively, and the refrigerator 20 is in different states.

[0041] When the evaporator 220 is connected to the refrigerant circulation heat exchange loop, please refer to... Figures 2 to 4 In other words, when the vehicle air conditioner is in cooling mode, the exhaust port 901 of the compressor 900, the external heat exchange component 100, the evaporator 220, and the return port 902 of the compressor 900 are connected in sequence. At this time, the refrigerant flow in the refrigerant circulation loop where the evaporator 220 of the air conditioning heat exchange component 200 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the external heat exchange component 100 and the evaporator 220 in sequence, and then flows back to the return port 902 of the compressor 900.

[0042] If the target operating mode of the vehicle refrigerator 20 is also the cooling mode at this time, then the exhaust port 901 of the compressor 900, the external heat exchange component 100, the first refrigerant channel 301, and the return port 902 of the compressor 900 are connected in sequence. Please refer to [link to details] for further information. Figure 3At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange component 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the outer heat exchange component 100 and the first refrigerant channel 301 in sequence, and then flows back to the return port 902 of the compressor 900.

[0043] If the target operating mode of the vehicle refrigerator 20 is heating mode at this time, then the exhaust port 901 of the compressor 900, the second refrigerant passage 302, the evaporator 220, and the return port 902 of the compressor 900 are connected in sequence; please refer to [link to details]. Figure 4 At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange component 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the second refrigerant channel 302 and the evaporator 220 in sequence, and then flows back to the return port 902 of the compressor 900.

[0044] When the condenser 210 is connected to the refrigerant circulation heat exchange loop, please refer to... Figures 5 to 7 In other words, when the vehicle air conditioner is in heating mode, the exhaust port 901 of the compressor 900, the condenser 210, the external heat exchange assembly 100, and the return port 902 of the compressor 900 are connected in sequence. At this time, the refrigerant flow in the refrigerant circulation loop where the condenser 210 of the air conditioning heat exchange assembly 200 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the condenser 210 and the external heat exchange assembly 100 in sequence, and then flows back to the return port 902 of the compressor 900.

[0045] If the target operating mode of the vehicle refrigerator 20 is cooling mode at this time, please refer to [link / reference needed]. Figure 6 Then, the exhaust port 901 of the compressor 900, the second refrigerant passage 302, the outer heat exchange component 100, and the return port 902 of the compressor 900 are connected in sequence. At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange component 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the second refrigerant passage 302 and the outer heat exchange component 100 in sequence, and then flows back to the return port 902 of the compressor 900.

[0046] If the target operating mode of the vehicle refrigerator 20 is heating mode at this time, please refer to [link / reference needed]. Figure 7Then, 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 connected in sequence. At this time, the refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange component 300 is located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the condenser 210 and the first refrigerant passage 301 in sequence, and then flows back to the return port 902 of the compressor 900.

[0047] In another embodiment, the air conditioning heat exchange assembly 200 includes an evaporator 220 and a condenser 210, one of which is connected to the refrigerant circulation heat exchange loop. Similar to the previous embodiment, by dividing the air conditioning heat exchange assembly 200 into independent condensers 210 and evaporators 220, different flow paths can be controlled more effectively using ordinary on / off valves to achieve different mode switching. Using ordinary shut-off valves to control the switching of different flow paths can reduce the noise generated by the switching device. The following will describe the refrigerant flow in the heat exchange system 10 when the evaporator 220 and condenser 210 are respectively connected to the refrigerant circulation loop, and the refrigerator 20 is in different states.

[0048] When the evaporator 220 is connected to the refrigerant circulation heat exchange circuit, that is, when the vehicle air conditioner is in cooling mode, in this embodiment, the evaporator 220 and the first refrigerant channel 301 are connected in series. At this time, the target operating mode of the vehicle refrigerator 20 is also cooling mode. Then, the exhaust port 901 of the compressor 900, the outer heat exchange component 100, the first refrigerant channel 301, the evaporator 220 and the return port 902 of the compressor 900 are connected in sequence. At this time, the refrigerant flow in the refrigerant circulation circuit where the evaporator 220 of the air conditioner heat exchange component 200 and the refrigerator heat exchange component 300 are located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the outer heat exchange component 100, the first refrigerant channel 301 and the evaporator 220 in sequence, and then flows back to the return port 902 of the compressor 900. In this embodiment, because the space of the vehicle refrigerator 20 is small and the amount of heat requiring exchange is small, the refrigerant first exchanges heat with the vehicle refrigerator 20 through the refrigerator heat exchange component 300, and then exchanges heat with the vehicle cabin interior space through the air conditioning heat exchange component 200, thus having minimal impact on the heat exchange of the vehicle cabin interior space. In other embodiments, the refrigerant may also first exchange heat with the vehicle cabin interior space through the air conditioning heat exchange component 200, and then exchange heat with the vehicle refrigerator 20 through the refrigerator heat exchange component 300.

[0049] Based on the previous embodiment, if the target operating mode of the vehicle refrigerator 20 is the heating mode, then the exhaust port 901 of the compressor 900, the external heat exchange assembly 100, the evaporator 220, and the return port 902 of the compressor 900 are sequentially connected, and the exhaust port 901 of the compressor 900, the second refrigerant passage 302, the evaporator 220, and the return port 902 of the compressor 900 are sequentially connected; at this time, the evaporator 22 of the air conditioning heat exchange assembly 200... The refrigerant flow in the refrigerant circulation loop where the refrigerator heat exchange component 300 is located is as follows: The refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, and then splits into two paths. One path flows through the outer heat exchange component 100 and the evaporator 220 in sequence, and then flows back to the return port 902 of the compressor 900. The other path flows through the second refrigerant passage 302 and the evaporator 220 in sequence, and then flows back to the return port 902 of the compressor 900.

[0050] When the condenser 210 is connected to the refrigerant circulation heat exchange circuit, that is, when the vehicle air conditioner is in heating mode, if the target operating mode of the vehicle refrigerator 20 is heating mode, then the exhaust port 901 of the compressor 900, the condenser 210, the first refrigerant channel 301, the outer heat exchange component 100, and the return port 902 of the compressor 900 are connected in sequence. The refrigerant flow in the refrigerant circulation circuit where the condenser 210 of the air conditioner heat exchange component 200 and the first refrigerant channel 301 and the second refrigerant channel 302 of the refrigerator heat exchange component 300 are located is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, flows through the condenser 210, the first refrigerant channel 301 and the outer heat exchange component 100 in sequence, and then flows back to the return port 902 of the compressor 900.

[0051] When the condenser 210 is connected to the refrigerant circulation heat exchange circuit, that is, when the vehicle air conditioner is in heating mode, if the target operating mode of the vehicle refrigerator 20 is cooling mode, then the exhaust port 901 of the compressor 900, the condenser 210, the external heat exchange component 100 and the return port 902 of the compressor 900 are connected in sequence, and the exhaust port 901 of the compressor 900, the condenser 210, the second refrigerant passage 302 and the return port 902 of the compressor 900 are connected in sequence. At this time, the refrigerant flow in the refrigerant circulation loop of the condenser 210 of the air conditioner heat exchange component 200 and the first refrigerant channel 301 and the second refrigerant channel 302 of the refrigerator heat exchange component 300 is as follows: the refrigerant compressed by the compressor 900 is discharged from the exhaust port 901 of the compressor 900, passes through the condenser 210, and then splits into two paths. One path flows through the outer heat exchange component 100 and then returns to the return port 902 of the compressor 900. The other path flows through the second refrigerant channel 302 and then returns to the return port 902 of the compressor 900.

[0052] In one embodiment, the heat exchange system 10 includes a flow regulating component, which typically functions as a throttling device during actual operation. Specifically, the flow regulating component plays the following roles in the heat exchange system 10: Adjusting refrigerant flow: This flow regulating component can throttle and reduce the pressure of the high-pressure liquid from the condenser 210 to a low-pressure liquid, while regulating the refrigerant flow into the evaporator 220, thereby ensuring that the refrigerant flow in the heat exchange system 10 is within a reasonable range.

[0053] Reduced heat exchange difficulty: For example, during the heat exchange process, the flow regulation component causes the refrigerant liquid to flow through a small orifice, creating a localized contraction, thereby increasing the flow velocity and reducing the static pressure. This pressure difference makes it easier for the refrigerant to evaporate in the evaporator 220, reducing the difficulty of heat exchange and improving heat exchange efficiency.

[0054] Temperature control: This flow regulation component also serves as a crucial element in temperature control. When the system requires a cooler temperature, the flow regulation component can be used to reduce the refrigerant flow, thereby lowering the evaporation temperature. Conversely, when the system requires a warmer temperature, the flow regulation component can be used to increase the refrigerant flow, thereby raising the evaporation temperature.

[0055] Furthermore, in this embodiment, the flow regulation component includes a first flow regulation valve 510, a second flow regulation valve 520, a third flow regulation valve 530, and a fourth flow regulation valve 540. The first flow regulation valve 510, the second flow regulation valve 520, the third flow regulation valve 530, and the fourth flow regulation valve 540 are respectively used to regulate the refrigerant flow in their respective flow paths, thereby enabling users to adjust the interior temperature of the vehicle cabin and the temperature of the vehicle refrigerator 20 as needed.

[0056] A first flow regulating valve 510 is located in the flow path between the condenser 210 and the outer heat exchange assembly 100; a second flow regulating valve 520 is located in the flow path between the outer heat exchange assembly 100 and the evaporator 220; a third flow regulating valve 530 is located in the first refrigerant passage 301, and is connected in series in the flow path between the refrigerator heat exchange assembly 300 and the outer heat exchange assembly 100, and is also connected in series in the flow path between the refrigerator heat exchange assembly 300 and the evaporator 220 or the condenser 210; a fourth flow regulating valve 540 is located in the second refrigerant passage 302, and is connected in series in the flow path between the refrigerator heat exchange assembly 300 and the outer heat exchange assembly 100, and is also connected in series in the flow path between the refrigerator heat exchange assembly 300 and the evaporator 220 or the condenser 210.

[0057] 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 typically includes a regulating chamber and an electronically operated valve for changing the volume of the regulating chamber. The electronically operated valve can automatically adjust its opening and closing state according to changes in system pressure and temperature, thereby achieving precise regulation of the refrigerant flow in its refrigerant circulation heat exchange loop.

[0058] Understandably, the flow regulating component adjusts the refrigerant flow rate in its refrigerant circulation heat exchange circuit by changing the volume of the regulating chamber connected in series in the branch circuit. This ensures that the refrigerant in the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 is always maintained at the most suitable refrigerant flow rate, thereby enabling the local refrigerant injection volume in the refrigerant circulation heat exchange circuit of the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 to reach the optimal amount, ensuring that the refrigerant in the air conditioning heat exchange component 200 and the refrigerator heat exchange component 300 always has a stable and sufficient heat exchange effect, thus meeting the heat exchange requirements of the vehicle air conditioner and the vehicle refrigerator 20.

[0059] In one embodiment, to ensure the heating effect of the refrigerator 20, please refer to... Figure 1 and Figure 9 The refrigerator heat exchange assembly 300 includes a heat exchange element 310 and a semiconductor cooling element 320. The heat exchange element 310 forms a first refrigerant channel 301 and a second refrigerant channel 302. The semiconductor cooling element 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 element 310. This embodiment integrates the heat exchange system of the vehicle refrigerator 20 and the heat exchange system of the car air conditioner. By using the cascade heat exchange of the heat exchange element 310 and the semiconductor cooling element 320, the noise of the heat exchange system 10 is reduced, while the cost of the heat exchange system 10 is also reduced.

[0060] Based on the previous embodiment, please continue to refer to... Figure 9 The heat exchanger 310 includes a heat-conducting plate 311 and a pipe 312. The pipe 312 forms the first refrigerant channel 301 and the second refrigerant channel 302. The pipe 312 is located on one side of the heat-conducting plate 311, and the side of the heat-conducting plate 311 opposite to the pipe 312 is attached to the semiconductor cooling component 320.

[0061] For information on heat exchanger 310, please refer to [link / reference]. Figure 9 The heat exchanger 310 includes a heat-conducting plate 311 and a pipe 312. The heat-conducting plate 311 has mounting positions, such as mounting holes 303, for adaptation and installation with other components (e.g., a thermoelectric cooler 320 or a vehicle refrigerator 20). The pipe 312 forms a channel for refrigerant flow and is located on one side of the heat-conducting plate 311. The side of the heat-conducting plate opposite to the pipe is attached to the thermoelectric cooler 320. Preferably, the pipe 312 is embedded in the heat-conducting plate 311, which can improve the heat exchange efficiency of the heat exchanger 310. In addition, the heat-conducting plate 311 is usually made of aluminum plate, which has the advantages of high heat exchange efficiency, light weight, and low price.

[0062] Furthermore, to improve the heat exchange efficiency of the heat exchanger 310, the pipe 312 is arranged in multiple bends, or the pipe 312 is arranged in multiple meandering bends. This increases the contact area between the heat-conducting plate 311 and the refrigerant in the pipe 312, thereby improving the heat exchange efficiency of the heat exchanger 310.

[0063] Regarding the thermoelectric cooler 320, it has a cold-side heat exchange surface and a hot-side heat exchange surface, which can be interchanged. When current flows through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer occurs between the two ends, creating a temperature difference and forming a cold and hot end. Therefore, by changing the direction of the current, the cold side can be turned into a hot side, and vice versa. This can be adjusted according to whether the cabinet needs cooling or heating.

[0064] In one embodiment, please refer to Figure 9 The heat exchange system 10 includes a fourth heat exchange component 400, which is used to exchange heat with the vehicle water tank; one end of the fourth heat exchange component 400 is connected to the return air port 902 of the compressor 900, and the other end is connected to the outer heat exchange component 100; or, the fourth heat exchange component 400 and the first refrigerant channel 301 are interconnected.

[0065] In this embodiment, by integrating the heat exchange components of the vehicle's water tank with the vehicle's air conditioning heat exchange system 10 and the vehicle's refrigerator 20 heat exchange system 10, the heat exchange capacity of the compressor 900 and the heat exchange system 10 can be utilized more efficiently. For example, in some usage scenarios, such as spring and autumn, when the vehicle's air conditioning is not required, when the vehicle's refrigerator 20 is running in heating mode, the cooling energy released by the vehicle's refrigerator 20 for heating can cool the vehicle's water tank through the refrigerant circulation heat exchange loop of the heat exchange system 10.

[0066] It should be understood that the vehicle-mounted water tank mentioned here is generally the cooling water tank for the vehicle's battery.
