[0045] The utility model provides a heat exchange system, wherein the heat exchange system can be applied to vehicles or other equipment requiring heat exchange.
[0046] See also Figures 1 to 4 In one embodiment of the utility model, the heat exchange system 10 includes a compressor 900, a first heat exchange component 100 and a second heat exchange component 200. The compressor 900 has an exhaust port 901 and a return port 902. The first heat exchange component 100 is used to exchange heat with the first space; the second heat exchange component 200 is used to exchange heat with the temperature adjustment device 400. The compressor 900, the first heat exchange component 100 and the second heat exchange component 200 are interconnected to form a refrigerant circulation heat exchange loop; the heat exchange system 10 also includes a bypass channel and a first control valve 500. The bypass channel has a first end and a second end. The first end is connected to the exhaust port 901 of the compressor 900, and the second end is connected to the return port 902 of the compressor 900; the first control valve 500 is used to control the conduction or isolation of the bypass channel.
[0047] Regarding the compressor 900, the main function of the compressor 900 is to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant to realize a refrigeration cycle. Its working principle is that the compressor 900 sucks the refrigerant from the air inlet through its internal reciprocating motion or rotational motion, and compresses it to be discharged from the exhaust port 901. In this process, the temperature and pressure of the refrigerant will increase to achieve a cooling or heating effect.
[0048] Regarding the temperature-adjustable device 400, in this embodiment, when applied to the vehicle, it can be a vehicle refrigerator, a vehicle insulation box, or a battery and water tank of the vehicle, etc. In the case of non-vehicle application, it is determined to be other components that need to adjust the temperature according to the actual application scenario. Examples are not given here one by one. It can be understood that, taking the temperature-adjustable device 400 requiring temperature adjustment (refrigeration condition) as an example, in this embodiment, the temperature-adjustable device 400 itself can generate heat. In this embodiment, a bypass channel is added. When the compressor 900 is in a shutdown state, through the principle of thermal expansion and contraction, the second heat exchange component 200 can also take away the heat generated by the temperature-adjustable device 400 to achieve heat exchange, thereby improving the heat exchange effect of the temperature-adjustable device 400, and then improving the efficiency or effect of temperature regulation at the temperature-adjustable device 400.
[0049] Exemplarily, the temperature-adjustable device 400 includes a box 410 with a storage space and a semiconductor refrigeration component 420, wherein the semiconductor refrigeration component 420 has a first heat exchange surface and a second heat exchange surface arranged opposite to each other, wherein the first heat exchange surface performs heat exchange with the box 410, and the second heat exchange surface performs heat exchange with the second heat exchange component 200. In other embodiments, the temperature-adjustable device 400 may also be a water tank, a battery, etc., which will not be described one by one here.
[0050] The first heat exchange assembly 100 is used to perform heat exchange with the first space, wherein the first space generally refers to other spaces except the internal space of the temperature-adjustable device 400. Of course, in order to ensure the efficiency of heat exchange, there is generally a certain distance between the first space and the temperature-adjustable device 400. In one embodiment, when the heat exchange system 10 is applied to a vehicle, the first space generally refers to the external space of the vehicle cabin, which can be understood as the first heat exchange assembly 100 is used to perform heat exchange with the external air of the vehicle.
[0051] The compressor 900, the first heat exchange component 100 and the second heat exchange component 200 are interconnected to form a refrigerant circulation heat exchange loop; wherein, when the second heat exchange component 200 is an evaporator, the first heat exchange component 100 is a condenser, and when the second heat exchange component 200 is a condenser, the first heat exchange component 100 is an evaporator. The following description is made by taking the second heat exchange component 200 as an evaporator and the first heat exchange component 100 as a condenser as an example. The compressor 900 has an exhaust port 901 and a return air port 902. The refrigerant circulation heat exchange loop can be formed by the exhaust port 901 of the compressor 900, the second heat exchange component 200, the first heat exchange component 100 and the return air port 902 of the compressor 900 being connected in sequence. At this time, the temperature adjustment device 400 is in a temperature adjustment condition (heating condition). When applied to this embodiment, the box body 410 is an insulation box. Alternatively, the refrigerant circulation heat exchange circuit can be formed by connecting the exhaust port 901 of the compressor 900, the first heat exchange component 100, the second heat exchange component 200 and the return air port 902 of the compressor 900 in sequence. At this time, the temperature-adjusting device 400 is in a cooling condition (refrigeration condition). When applied to this embodiment, the box body 410 is a refrigerator. In this embodiment, by adding a bypass channel between the exhaust port 901 and the return air port 902 of the compressor 900, when the temperature-adjusting device 400 is in a cooling condition (refrigeration condition), the heat exchange effect is more significant.
[0052] Regarding the bypass channel, the bypass channel has a first end and a second end, the first end is communicated with the exhaust port 901 of the compressor 900, and the second end is communicated with the return air port 902 of the compressor 900. It should be understood that during the normal operation of the compressor 900, the bypass channel is in a partitioned state. For details, please refer to Figure 2 When the compressor 900 is stopped, the bypass channel may be in a conducting state. For details, see Figure 3 and Figure 4 .
[0053] Regarding the first control valve 500, the first control valve 500 is used to control the refrigerant flow in the bypass channel, wherein the first control valve 500 is usually arranged on the bypass channel. Of course, when the first control valve 500 uses a three-way valve, it can be arranged at the connection between the return air port 902 of the compressor 900 and the bypass channel, or it can be arranged at the connection between the exhaust port 901 of the compressor 900 and the bypass channel. In this embodiment, in order to reduce noise and reduce manufacturing costs, the first control valve 500 uses an ordinary on-off valve. In other embodiments, the first control valve 500 can also be an electronic expansion valve, etc.
[0054] The technical solution of the utility model is to add a bypass channel connected to the exhaust port 901 and the return port 902 of the compressor 900. When the compressor 900 is in a shutdown state, the bypass channel is switched to a conducting state, thereby forming a refrigerant circulation heat exchange loop. When the temperature difference between the refrigerant at the second heat exchange component 200 and the temperature at the first heat exchange component 100 is large, based on the principle of thermal expansion and contraction of the refrigerant, a pressure difference is generated in the refrigerant circulation heat exchange loop, thereby promoting the flow of the refrigerant in the refrigerant circulation heat exchange loop, and then improving the heat exchange effect at the temperature-adjusting device 400.
[0055] Among them, in the heat exchange system, the role of the compressor 900 is to provide power for the refrigerant circulation. Take the compressor as a piston compressor as an example, Figure 3 and Figure 4 As shown, when the compressor 900 is in the shutdown state, the first control valve 500 switches to the on state. At this time, because the piston of the compressor 900 stops reciprocating motion, the return air port 902 and the exhaust port 901 inside the compressor 900 are not connected, and the refrigerant cannot circulate normally.
[0056] For the sake of convenience, the following description is made by taking the case where the temperature-adjustable device 400 is a vehicle refrigerator and the vehicle refrigerator needs to be refrigerated as an example. At this time, when the compressor 900 is in a shutdown state, the bypass channel is in a conducting state, that is, a closed loop is formed between the bypass channel, the first heat exchange component 100 and the second heat exchange component 200. When the vehicle refrigerator needs to be refrigerated, that is, the semiconductor refrigeration component 420 is in a working state, the cold end of the semiconductor refrigeration component 420 exchanges heat with the body of the vehicle refrigerator, and the hot end of the semiconductor refrigeration component 420 exchanges heat with the second heat exchange component 200, so that the refrigerant temperature at the second heat exchange component 200 is higher than the refrigerant temperature at other positions of the refrigerant circulation heat exchange loop.
[0057] Based on the principle of thermal expansion and contraction, the second heat exchange component 200 is heated, so that the pressure in the tube of the second heat exchange component 200 is greater than the pressure in the tube of other positions of the refrigerant circulation heat exchange loop, so that a pressure difference is generated between the second heat exchange component 200 and other positions of the refrigerant circulation heat exchange loop, and the pressure difference can drive the refrigerant to circulate in the closed loop. When the high-temperature refrigerant at the second heat exchange component 200 flows to the first heat exchange component, the first heat exchange component 100 can cool the high-temperature refrigerant by natural convection, or the fan at the first heat exchange component 100 can be turned on to enhance heat exchange. In this way, this embodiment can take away the heat generated by the semiconductor refrigeration component 420 at the vehicle refrigerator without the drive of the compressor 900, thereby improving the heat exchange effect at the vehicle refrigerator (temperature adjustment device 400).
[0058] In one embodiment, see Figure 3 and Figure 4The heat exchange system 10 also includes a third heat exchange component 300, which is used to exchange heat with the second space; at least one of the first heat exchange component 100 and the third heat exchange component 300 and the second heat exchange component 200 can be connected to the bypass channel to form a refrigerant circulation heat exchange loop.
[0059] Regarding the third heat exchange component 300 used for heat exchange with the second space, wherein the second space refers to other spaces except the first space. In one embodiment, when the heat exchange system 10 is applied to a vehicle, the second space generally refers to the interior space of the vehicle cabin. It can be understood that the third heat exchange component 300 is used for heat exchange with the interior air of the vehicle cabin.
[0060] With respect to at least one of the first heat exchange component 100 and the third heat exchange component 300, the second heat exchange component 200 may be connected to the bypass channel to form a refrigerant circulation heat exchange loop. That is to say, when the compressor 900 is in a shutdown state, through the setting of the bypass channel, the second heat exchange component 200 may be connected to the first heat exchange component 100 to form a refrigerant circulation heat exchange loop, or the second heat exchange component 200 may be connected to the first heat exchange component 100 and the third heat exchange component 300 at the same time to form a refrigerant circulation heat exchange loop. In other embodiments, the first heat exchange component 100 and the third heat exchange component 300, and the second heat exchange component 200 may be connected to the compressor 900 to form a refrigerant circulation heat exchange loop.
[0061] See also Figure 1 In an exemplary embodiment, the temperature regulating device 400 takes a vehicle refrigerator as an example, and the return air port 902 of the compressor 900 is respectively connected to the first end of the second heat exchange component 200 and the first end of the third heat exchange component 300; the exhaust port 901 of the compressor 900 is connected to the first end of the first heat exchange component 100; the second end of the first heat exchange component 100, the second end of the second heat exchange component 200 and the second end of the third heat exchange component 300 are connected to each other.
[0062] On the basis of the previous embodiment, when the compressor 900 stops, in order to avoid the second heat exchange component 200 from exchanging heat with the interior of the cabin, the comfort of the interior environment of the cabin is improved. The heat exchange system 10 also includes a second control valve 600; the second control valve 600 is arranged at the first end of the third heat exchange component 300, or the second control valve 600 is arranged at the second end of the third heat exchange component 300; the second control valve 600 is used to control the refrigerant flow of the third heat exchange component 300. In this way, through the setting of the second control valve 600, when the compressor 900 stops, the second heat exchange component 200 can be controlled to exchange heat with the first heat exchange component 100 arranged outside the cabin, and the second heat exchange component 200 can be avoided from exchanging heat with the interior of the cabin, thereby improving the comfort of the interior environment of the cabin.
[0063] Regarding the second control valve 600, similar to the first control valve 500, the second control valve 600 is used to control the refrigerant flow of the third heat exchange component 300. Among them, the second control valve 600 is usually set on the branch where the third heat exchange component 300 is located. Of course, when the second control valve 600 uses a three-way valve, it can be set at the connection between the return air port 902 of the compressor 900, the second heat exchange component 200, and the third heat exchange component 300, or it can be set at the second end of the first heat exchange component 100, the second end of the second heat exchange component 200, and the second end of the third heat exchange component 300. In this embodiment, in order to reduce noise and reduce manufacturing costs, the first control valve 500 uses an ordinary on-off valve. In other embodiments, the first control valve 500 can also be an electronic expansion valve, etc.
[0064] In an exemplary embodiment, in order to reduce the noise of the heat exchange system 10, the first control valve 500 is an on-off valve; and / or the second control valve 600 is an on-off valve.
[0065] In one embodiment, in order to improve the heat exchange efficiency of the heat exchange system 10, the heat exchange system 10 includes a gas-liquid separator 700, which is arranged on the flow path between the return air port 902 of the compressor 900 and the first end of the second heat exchange component 200; or, the gas-liquid separator 700 is arranged on the flow path between the return air port 902 of the compressor 900 and the first end of the third heat exchange component 300. In this embodiment, the gas-liquid separator 700 is used to prevent excessive compressor 900 oil in the compressor 900 heat exchange system 10 from circulating in the system and affecting the heat exchange effect.
[0066] In a preferred embodiment, the temperature adjustment device 400 includes a box 410 with a storage space and a semiconductor refrigeration element 420, wherein the semiconductor refrigeration element 420 has a first heat exchange surface and a second heat exchange surface arranged opposite to each other, wherein the first heat exchange surface performs heat exchange with the box 410, and the second heat exchange surface performs heat exchange with the second heat exchange assembly 200. In this embodiment, through the semiconductor refrigeration element 420 and the scheme of sharing the refrigerant circulation heat exchange circuit with the vehicle air conditioner, compared with a separate semiconductor vehicle refrigerator, there is no need to set up an additional fan to accelerate the heat exchange for the semiconductor refrigeration element, and the heat dissipation effect is better and the noise is lower, and the low cost effect of the semiconductor vehicle refrigerator is also achieved. Compared with the independent compressor vehicle refrigerator, it has the advantages of better temperature adjustment capability, lower cost, and can be used when the compressor is stopped. Compared with the vehicle refrigerator sharing the compressor of the vehicle air conditioner, it has the advantages of better temperature adjustment capability and can be used when the compressor is stopped.
[0067] It is understandable that the semiconductor refrigeration element 420 has a cold side heat exchange surface or a hot side heat exchange surface, and the cold side and the hot side of the semiconductor refrigeration element 420 can be switched. When a current passes through a thermocouple pair formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form a cold and hot end. Therefore, by changing the direction of the current, the cold side can be changed to a hot side, and the hot side can be changed to a cold side.
[0068] In this embodiment, the first heat exchange surface may be the cold side heat exchange surface and the second heat exchange surface may be the hot side heat exchange surface; or the first heat exchange surface may be the hot side heat exchange surface and the second heat exchange surface may be the cold side heat exchange surface. The specific adjustment may be made according to whether the box 410 needs to be cooled or heated.
[0069] Based on the previous embodiment, please refer to Figure 1 In order to further improve the heat exchange efficiency, the first heat exchange surface of the semiconductor refrigeration element 420 abuts against the box body 410, and / or the second heat exchange surface of the semiconductor refrigeration element 420 abuts against the second heat exchange component 200. The second heat exchange component 200 adopts a plate heat exchanger.
[0070] In one embodiment, please continue to refer to Figure 1 The first heat exchange component 100 includes a fan and a heat exchange body, and the fan is used to supply air to the heat exchange body; and / or the third heat exchange component 300 includes a fan and a heat exchange body, and the fan is used to supply air to the heat exchange body.
[0071] Among them, the heat exchange body can be a fin-tube heat exchanger, a micro-tube heat exchanger or a plate heat exchanger. The working principle of the fin-tube heat exchanger is that when the refrigerant flows through the circulating refrigerant tube, heat is exchanged with the surrounding air through the tube wall of the refrigerant tube and the cooling fins. The cooling fins increase the contact area between the heat exchanger and the surrounding air, thereby improving the heat exchange efficiency. A certain refrigerant flow path is formed in the plate-type pipe of the plate heat exchanger. When the refrigerant flows through these refrigerant flow paths, the tube wall of the plate-type pipe exchanges heat with the surrounding air. The micro-tube heat exchanger includes a refrigerant inlet mother pipe, a refrigerant outlet mother pipe, a plurality of flat shunt pipes and a plurality of cooling fins. Several micro refrigerant flow paths are formed in the flat shunt pipes, which are evenly spaced between the refrigerant inlet mother pipe and the refrigerant outlet mother pipe.
[0072] In this embodiment, in order to improve the heat exchange efficiency of the first heat exchange component 100 and / or the third heat exchange component 300, the first heat exchange component 100 and / or the third heat exchange component 300 also includes a fan, which is used to supply air to the heat exchange body. By using the fan, the heat exchange efficiency of the first heat exchange component 100 and / or the third heat exchange component 300 is improved.
[0073] The utility model also proposes a vehicle, which includes a vehicle body and a heat exchange system 10. The specific structure of the heat exchange system 10 refers to the above-mentioned embodiment.
