Description

Technical Field

[0001] This utility model relates to the field of thermal management technology, and in particular to a condenser, a thermal management system, and a vehicle. Background Technology

[0002] Vehicles are equipped with a thermal management system to regulate the temperature of the passenger compartment or power battery. The thermal management system includes a compressor, receiver-dryer, expansion valve, condenser, and evaporator. The condenser uses liquid cooling for heat exchange. Due to the limited space in vehicles, the thermal management system needs to be miniaturized to reduce its footprint. In related technologies, the condenser integrates condensation channels and heat exchange channels, and also includes a refrigerant circuit directly connected to the compressor inlet. The condensation channel connects to the compressor outlet, the heat exchange channel receives the heat exchange medium, and the two ends of the refrigerant circuit connect to the evaporator outlet and the compressor inlet, respectively. Because the refrigerant circuit is located on the condenser, the refrigerant in the circuit easily exchanges heat with the heat exchange channels, leading to a decrease in compressor performance.

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0049] Reference Figure 1 As shown, a thermal management system 1000 according to an embodiment of this utility model includes a compressor 500, a condenser 100, a liquid receiver 200, an expansion valve 300, and an evaporator 400. The compressor 500, condenser 100, liquid receiver 200, and evaporator 400 are connected sequentially in a left-right direction, while the expansion valve 300 is connected to the liquid receiver 200. When the thermal management system 1000 is applied to a vehicle, due to the limited space inside the vehicle, the overall structure of the thermal management system 1000 needs to be designed to be more compact. For example, in addition to integrating a heat exchange channel, the condenser 100 will also be provided with a refrigerant circuit that is directly connected to the air inlet of the compressor 500 to reduce the use of piping. The heat exchange channel is connected to the air outlet of the compressor 500 and is used to collect water, while the two ends of the refrigerant circuit are respectively connected to the air outlet of the evaporator 400 and the air inlet of the compressor 500.

[0050] To reduce heat exchange between the refrigerant and the condensation and heat exchange channels in the refrigerant circuit, refer to Figure 2 , Figure 3 and Figure 4 As shown, a condenser 100 according to an embodiment of the present invention can be used in a thermal management system 1000. The condenser 100 of this embodiment includes a body 110 and a first heat insulation member 120. The body 110 has a condensing flow channel 173 and a first heat exchange flow channel 174 inside. The condensing flow channel 173 is used for refrigerant flow, and the first heat exchange flow channel 174 is used for heat exchange medium flow. The heat exchange medium can be water, glycerin, etc. For ease of explanation, water will be used as an example in the following description. The body 110 also has a first refrigerant circuit 113, which runs through opposite sides of the body 110. The first refrigerant circuit 113 is independently configured from the condensing flow channel 173 and the first heat exchange flow channel 174; that is, the first refrigerant circuit 113 is not connected to the condensing flow channel 173 within the condenser 100. The first heat insulation member 120 is disposed within the first refrigerant circuit 113, and a channel for refrigerant to pass through is formed within the first heat insulation member 120.

[0051] Understandably, with the above scheme, the condenser channel 173 is connected to the outlet of the compressor 500, and the first heat exchange channel 174 is connected to the circulating water circuit. When the high-temperature, high-pressure refrigerant in the compressor 500 enters the condenser channel 173, it can exchange heat with the first heat exchange channel 174, thereby reducing the temperature of the refrigerant and facilitating refrigerant liquefaction. The first refrigerant circuit 113 is used to transport the refrigerant discharged from the evaporator 400 to the inlet of the compressor 500. By setting the first refrigerant circuit 113 on the main body 110, the use of piping can be reduced, which is beneficial to the compact design of the thermal management system 1000. Among them, the first heat insulation component 120 is set in the first refrigerant circuit 113, which can effectively reduce the heat exchange between the refrigerant in the first refrigerant circuit 113 and the condenser channel 173 and the first heat exchange channel 174, thereby ensuring that the temperature of the refrigerant entering the compressor 500 from the first refrigerant circuit 113 is within a suitable range, so as to improve the working performance of the compressor 500.

[0052] Reference Figure 3 , Figure 5 and Figure 6 As shown, in an embodiment of this utility model, the body 110 includes an end plate 111, which is located at one end of the body 110 along the extending direction of the first refrigerant circuit 113. For example, the first refrigerant circuit 113 extends in a left-right direction, and the end plate 111 is located at the right end of the body 110. The first refrigerant circuit 113 includes a first segment 1131 and a second segment 1132, which are connected. The second segment 1132 is formed on the end plate 111, and the minimum width of the second segment 1132 is smaller than the minimum width of the first segment 1131. For example, the cross-sections of both the first segment 1131 and the second segment 1132 are circular, and the inner diameter of the second segment 1132 is smaller than the inner diameter of the first segment 1131. The first heat insulation element 120 is installed in the first section 1131, and one end of the first heat insulation element 120 can abut against and limit the end plate 111 on the side facing the first section 1131, thereby restricting the first heat insulation element 120 from leaving the first refrigerant circuit 113.

[0053] Reference Figure 6 As shown in the embodiment of this utility model, the first heat insulation member 120 is elastic and cylindrical, and the first heat insulation member 120 is provided with a notch 121, which extends along the axial direction of the first heat insulation member 120 and penetrates both ends of the first heat insulation member 120. With this design, when installing the first heat insulation member 120, due to the presence of the notch 121, the first heat insulation member 120 can narrow under external force, making its outer diameter smaller, thus allowing it to pass through the second section 1132 and enter the first section 1131. After the external force is removed, the first heat insulation member 120 expands as a whole and can abut against the end plate 111, thereby preventing the first heat insulation member 120 from detaching from the first refrigerant circuit 113.

[0054] In this embodiment of the invention, the first heat insulation component 120 is made of plastic or rubber. It is understood that both rubber and plastic are poor conductors; if they are made into microporous or foamed structures, their thermal conductivity will be even lower. Materials with low thermal conductivity can effectively block heat transfer. Rubber materials can be used for extended periods at 260°C and can withstand even higher temperatures for short periods. Therefore, the first heat insulation component 120 made of rubber has good thermal stability and high reliability. The rubber material can be silicone rubber, fluororubber, natural rubber foam, etc.; the plastic material can be polyethylene, polypropylene, polyurethane foam, polyterephthalic acid plastic, etc., with the appropriate material selected based on the specific circumstances.

[0055] Reference Figure 3 and Figure 4 As shown in the embodiment of this utility model, a first refrigerant outlet 140 is provided at the end of the main body 110 away from the end plate 111, that is, the first refrigerant outlet 140 is provided at the left end of the main body 110. In the vertical direction, that is, the up-down direction, the first refrigerant outlet 140 is located below the first refrigerant inlet 130. Therefore, the refrigerant flows from top to bottom in the condensation channel 173, from the right end of the main body 110 to the left end, and finally enters the liquid storage tank 200. By adopting the above scheme, gravity-assisted refrigerant flow can reduce pressure drop and optimize the overall temperature distribution of the main body 110, so that the high-temperature zone is at the top and the low-temperature zone is at the bottom, which is beneficial for heat dissipation of the main body 110.

[0056] To improve the heat exchange efficiency of the refrigerant, the refrigerant flow direction in the condenser channel 173 can be opposite to the water flow direction in the first heat exchange channel 174. For example, continue referring to... Figure 3 As shown in the embodiment of this utility model, the end plate 111 is provided with a heat exchange inlet 114 and a heat exchange outlet 115 at intervals, and the heat exchange inlet 114 and the heat exchange outlet 115 are respectively connected to the first heat exchange channel 174. Water can be connected to the first heat exchange channel 174. For example, water enters multiple first heat exchange channels 174 through the heat exchange inlet 114 and finally exits from the heat exchange outlet 115. Along the vertical direction, that is... Figure 3 In the vertical direction, the heat exchange outlet 115 is located above the heat exchange inlet 114. It can be understood that the water in the first cooling channel flows from bottom to top, opposite to the refrigerant flow direction from bottom to top in the condensation channel 173. Because the temperature of the refrigerant gradually decreases as it flows downwards, while the temperature of the water gradually increases as it flows upwards, the temperature difference between the refrigerant and water is more uniform and a larger temperature difference is maintained between them, resulting in higher heat exchange efficiency for the refrigerant.

[0057] It should be noted that the refrigerant flowing from top to bottom and the water flowing from bottom to top mentioned in the above embodiments only refer to the flow trend being from top to bottom or from bottom to top, and should not be simply understood as flowing straight up and down. Taking the refrigerant flow as an example, the condenser channel 173 can be designed in a reciprocating bending form, that is, while extending from top to bottom, the condenser channel 173 also bends back and forth in the front and back directions, thereby lengthening the flow path of the refrigerant and enabling more effective heat exchange with the water. Of course, designing the condenser channel 173 in a straight up and down form is also feasible; the appropriate solution should be selected based on the actual situation.

[0058] Reference Figure 7 , Figure 8 and Figure 9 As shown in the embodiment of this utility model, the body 110 includes a plurality of perimeters 190 and a plurality of first heat exchange plate assemblies 170 arranged and connected sequentially along a first direction, wherein the first direction is... Figure 8 The diagram shows the left-right direction. Multiple perimeters 190 are correspondingly connected between adjacent first heat exchanger plate assemblies 170. At least a portion of the structure of adjacent first heat exchanger plate assemblies 170 is spaced apart within the perimeters 190, forming condensation channels 173 for refrigerant flow within the perimeters 190. Each first heat exchanger plate assembly 170 includes a first partition 171 and a second partition 172 connected together. A first heat exchange channel 174 is formed between the first partition 171 and the second partition 172. The first heat exchange channel 174 is connected to a heat exchange medium, such as water or glycerin. In subsequent embodiments, water is used as an example for illustration. The condensation channel 173 and the first heat exchange channel 174 are isolated; that is, they are not connected.

[0059] Reference Figure 9 As shown in the embodiment of this utility model, in the first partition 171 and the second partition 172 of the first heat exchange plate assembly 170, the outer edge of the first partition 171 is bent towards the second partition 172 to form a first folded edge 191, and the outer edge of the second partition 172 is bent away from the first partition 171 to form a second folded edge 192. The second folded edge 192 and the first folded edge 191 are connected, and the first folded edge 191 and the second folded edge 192 together constitute the surrounding edge 190. Using the above solution simplifies the assembly steps of the first partition 171 and the second partition 172 and improves assembly efficiency.

[0060] Reference Figure 8 and Figure 9As shown in the embodiment of this utility model, the first heat exchange plate assembly 170 is provided with an air inlet, which is connected to the condenser channel 173, and multiple air inlets are correspondingly connected to multiple condenser channels 173. The end plate 111 is provided with a first refrigerant inlet 130, which is connected to the air inlet, and the outlet of the compressor 500 is connected to the first refrigerant inlet 130. The body 110 is also provided with a first refrigerant outlet 140, which is connected to the condenser channel 173, and the first refrigerant outlet 140 is also connected to the inlet of the liquid storage tank 200. Among them, one of two adjacent air inlets is a first air inlet 175, and the other is a second air inlet 176, and the minimum width of the first air inlet 175 is greater than the minimum width of the second air inlet 176. For example, in all the air intakes, two adjacent ones are configured as the first air intake 175 and the second air intake 176, and the first air intake 175 and the second air intake 176 are alternately arranged in the left-right direction. Alternatively, in some air intakes, one adjacent one is the first air intake 175 and the other is the second air intake 176, and the appropriate scheme is selected according to the actual situation.

[0061] The refrigerant discharged from the compressor 500 enters the condenser channel 173 through the first refrigerant inlet 130 and is distributed to different condenser channels 173 through multiple air inlets. Since the adjacent condenser channels 173 are provided with first heat exchange channels 174, the water in the heat exchange channels can exchange heat with the refrigerant in the condenser channels 173, causing the refrigerant to change from a gaseous state to a liquid state. Finally, the refrigerant in the condenser channels 173 is discharged from the condenser 100 through the first refrigerant outlet 140. Since the minimum width of the first air inlet 175 is greater than the minimum width of the second air inlet 176, and the first air inlet 175 and the second air inlet 176 are arranged alternately along the first direction, when the refrigerant enters the second air inlet 176 from the first air inlet 175, some of the refrigerant will be blocked by the structure around the second air inlet 176, which increases the flow resistance of the refrigerant, thereby reducing exhaust pulsation, reducing the vibration and noise of the condenser 100, and improving the reliability of the condenser 100.

[0062] Reference Figure 10 As shown, Figure 10The multiple first heat exchange plate assemblies 170 in the diagram are for simplification. In this embodiment of the present invention, the minimum width of the first air inlet 175 is W1, and the minimum width of the second air inlet 176 is W2, satisfying: 0.5≤W2 / W1≤0.8. For example, the value of W2 / W1 can be 0.5, 0.6, 0.7, 0.8, etc. It is understood that when the ratio of W2 / W1 is less than 0.5, that is, when the minimum width W1 of the first air inlet 175 is too large, or the minimum width W2 of the second air inlet 176 is too small, the resistance to the movement of the refrigerant increases significantly, which will increase the non-uniformity of the refrigerant distribution to different condensing channels 173, which is not conducive to improving the heat exchange efficiency of the condenser 100. When the ratio of W2 / W1 is greater than 0.8, meaning the minimum width W1 of the first air inlet 175 and the minimum width W2 of the second air inlet 176 are close, it is difficult to increase the refrigerant flow resistance, and the condenser 100 is prone to vibration and noise. Therefore, by reasonably designing the ratio of W2 / W1 to be within the range of 0.5 to 0.8, the refrigerant flow resistance can be appropriately adjusted, reducing the vibration and noise of the condenser 100 while also ensuring a more uniform distribution of the refrigerant within the different condensing channels 173.

[0063] Reference Figure 9 As shown, in this embodiment of the present invention, the first air inlet 175 is configured closest to the first refrigerant inlet 130, and the minimum width of the first air inlet 175 is greater than or equal to the minimum width of the first refrigerant inlet 130. For example, both the first air inlet 175 and the first refrigerant inlet 130 have circular cross-sections, and the inner diameter of the first air inlet 175 is greater than or equal to the inner diameter of the first refrigerant inlet 130. It is understood that if the minimum width of the first air inlet 175 is less than the minimum width of the first refrigerant inlet 130, when the refrigerant passes through the first refrigerant inlet 130, it is easy for some of the refrigerant to come into contact with the structure around the first air inlet 175, thereby hindering subsequent refrigerant from continuing to pass through the first air inlet 175. That is, it is desirable for the flow resistance of the refrigerant within the body 110 to increase, but it is undesirable for the resistance to increase at the first refrigerant inlet 130. By designing the minimum width of the first air inlet 175 to be greater than or equal to the minimum width of the first refrigerant inlet 130, the refrigerant can smoothly pass through the first air inlet 175 when passing through the first refrigerant inlet 130. Since a condensation channel 173 is provided between adjacent first air inlets 175 and second air inlets 176, and the minimum width of the second air inlet 176 is less than the minimum width of the first air inlet 175, when a portion of the refrigerant comes into contact with the structure surrounding the second air inlet 176, this portion of the refrigerant can be guided into the condensation channel 173, thereby improving the uniformity of refrigerant distribution.

[0064] To reduce the overall size of the thermal management system 1000 and make its overall structure more compact, refer to Figure 8 and Figure 9 As shown in the embodiment of this utility model, the main body 110 further includes a plurality of second heat exchange plate groups 180 arranged and connected sequentially in the left-right direction. The second heat exchange plate group 180 includes a third partition 181 and a fourth partition 182, which extend vertically and are connected to each other. A second heat exchange channel 184 is formed between the third partition 181 and the fourth partition 182. The second heat exchange channel 184 can be connected to the heat exchange medium of other circulation loops, or it can be directly connected to the first heat exchange channel 174. One of the plurality of second heat exchange plate groups 180 is connected to the first heat exchange plate group 170 farthest from the end plate 111. A subcooling channel 183 is formed between adjacent second heat exchange plate groups 180, and the subcooling channel 183 is isolated from the second heat exchange channel 184. The second heat exchange plate assembly 180 is provided with a second refrigerant inlet 150 and a second refrigerant outlet 160 at intervals. The second refrigerant inlet 150 and the second refrigerant outlet 160 are respectively connected to the subcooling channel 183. The second refrigerant inlet 150 is also connected to the outlet of the liquid storage tank 200, and the second refrigerant outlet 160 is also connected to the inlet of the expansion valve 300.

[0065] Understandably, the refrigerant in the condenser channel 173 is discharged to the liquid storage tank 200 through the first refrigerant outlet 140. The refrigerant in the liquid storage tank 200 then enters the subcooling channel 183 through the second refrigerant inlet 150. The refrigerant in the subcooling channel 183 exchanges heat with the water in the second heat exchange channel 184, further reducing the temperature. Finally, the refrigerant in the subcooling channel 183 is discharged through the second refrigerant outlet 160 and enters the expansion valve 300, which can effectively reduce the parameters of flash gas and improve the cooling effect. At the same time, since the subcooling channel 183 is integrated into the main body 110, there is no need to set up an additional subcooler, thus reducing the overall volume of the thermal management system 1000 and making the overall structure of the thermal management system 1000 more compact.

[0066] Reference Figure 11 As shown in the embodiment of this utility model, the edge of the first partition 171 is provided with a first folded edge 191 bent toward the second partition 172. A guide rib 1713 is provided on the side of the first partition 171 facing the second partition 172. One end of the guide rib 1713 is connected to the first folded edge 191 on one side of the first partition 171, and the other end of the guide rib 1713 extends toward the opposite side of the first folded edge 191, and is spaced apart from the corresponding first folded edge 191. Since the first heat exchange channel 174 is located between the first partition 171 and the second partition 172, the guide rib 1713 allows the water in the first heat exchange channel 174 to flow along... Figure 11 The direction of the dashed arrow in the middle extends the distance the water travels within the first heat exchange channel 174, thereby increasing the heat exchange efficiency.

[0067] Continue to refer to Figure 11As shown in the embodiment of this utility model, a baffle 1712 is provided on the side of the first partition 171 facing the second partition 172. Both ends of the baffle 1712 are connected to the first folded edge 191. The baffle 1712 abuts against the second partition 172, thereby preventing water in the first heat exchange channel 174 from entering the area enclosed by the first folded edge 191 and the baffle 1712. A first corner hole 1711 is provided in the area enclosed by the first folded edge 191 and the baffle 1712. The edge of the first corner hole 1711 is bent toward the second partition 172 to form a first annular portion 1715. The second partition 172 is provided with a second corner hole, which is not shown in the figure, but can be understood by referring to the structure of the first corner hole. The edge of the second corner hole is bent toward the first partition 171 of the adjacent first heat exchange plate group 170 to form a second annular portion. The first annular portion 1715 is frustoconical, so that the first annular portion 1715 is more accurately inserted into the second corner hole. The structure of the second annular portion is similar to that of the first annular portion 1715, for example, both being frustoconical, allowing the second annular portion to be smoothly inserted into the first corner hole 1711 of an adjacent first partition 171. The adjacent first partition 171 refers to the first partition 171 of an adjacent first heat exchange plate assembly 170. The first corner holes 1711 and second corner holes of multiple first heat exchange plate assemblies 170 are sequentially connected along a first direction to form a first refrigerant circuit 113. The protruding direction of the first annular portion 1715 and the second annular portion is the same as the refrigerant flow direction within the first refrigerant circuit 113, reducing refrigerant flow resistance and ensuring smoother flow.

[0068] A thermal management system 1000 according to one embodiment of this utility model includes a compressor 500, a condenser 100, a liquid receiver 200, an expansion valve 300, and an evaporator 400. The compressor 500, condenser 100, liquid receiver 200, and evaporator 400 are arranged along a first direction and connected sequentially. The expansion valve 300 is connected to the upper end of the liquid receiver 200. The outlet of the compressor 500 is connected to a first refrigerant inlet 130, the first refrigerant outlet 140 is connected to the inlet of the liquid receiver 200, the outlet of the liquid receiver 200 is connected to the inlet of the expansion valve 300, the outlet of the expansion valve 300 is connected to the inlet of the evaporator 400, the outlet of the evaporator 400 is connected to a first refrigerant circuit 113, and the first refrigerant circuit 113 is connected to the inlet of the compressor 500. Therefore, the refrigerant discharged from the compressor 500 passes through the condenser 100, the liquid receiver 200, the expansion valve 300, and the evaporator 400, and finally returns to the compressor 500.

[0069] The thermal management system 1000 of this embodiment adopts the condenser 100 of the above embodiment. A condensing channel 173 and a first heat exchange channel 174 are provided within the main body 110. The main body 110 has a first refrigerant circuit 113 running through both ends of the main body 110, and the first refrigerant circuit 113 is isolated from the condensing channel 173 and the first heat exchange channel 174. The condensing channel 173 is connected to the outlet of the compressor 500, and the first heat exchange channel 174 is externally connected to water. When the high-temperature, high-pressure refrigerant from the compressor 500 enters the condensing channel 173, it can exchange heat with the first heat exchange channel 174, thereby reducing the temperature of the refrigerant and facilitating refrigerant liquefaction. The first refrigerant circuit 113 is used to transport the refrigerant discharged from the evaporator 400 to the inlet of the compressor 500. By placing the first refrigerant circuit 113 on the main body 110, the use of piping can be reduced, which is beneficial to the compact design of the thermal management system 1000. The first heat insulation component 120 is disposed in the first refrigerant circuit 113, which can effectively reduce the heat exchange generated by the refrigerant in the first refrigerant circuit 113, the condenser channel 173 and the first heat exchange channel 174, thereby ensuring that the temperature of the refrigerant entering the compressor 500 from the first refrigerant circuit 113 is within a suitable range, so as to improve the working performance of the compressor 500.

[0070] Reference Figure 2 As shown, in this embodiment of the present invention, the liquid storage tank 200 is connected to the side of the condenser 100 away from the end plate 111, the evaporator 400 is connected to the side of the liquid storage tank 200 away from the condenser 100, and the expansion valve 300 is connected to the upper end of the evaporator 400. (Refer to...) Figure 3 As shown, the liquid receiver 200 has a third refrigerant inlet 210 and a third refrigerant outlet 220 on the side facing the condenser 100. Both the third refrigerant inlet 210 and the third refrigerant outlet 220 are located slightly lower on the liquid receiver 200 and are spaced apart horizontally. It can be understood that by placing the third refrigerant inlet 210 slightly lower on the liquid receiver 200, it corresponds to the position of the first refrigerant outlet 140 on the condenser 100, facilitating direct connection between the two via a connector and reducing the use of piping. The upper end of the liquid receiver 200 has a mounting groove 260, which is a recessed groove used to install the expansion valve 300. The side of the liquid receiver 200 facing the condenser 100 has a fourth refrigerant inlet 230, which communicates with the inlet of the expansion valve 300 and is also connected to the second refrigerant outlet 160. (Refer to...) Figure 4 As shown, the liquid storage tank 200 has a fourth refrigerant outlet 240 on the side facing the evaporator 400, and the fourth refrigerant outlet 240 is connected to the outlet of the expansion valve 300.

[0071] Reference Figure 4As shown in the embodiment of this utility model, the liquid storage tank 200 is further provided with a second refrigerant circuit 250. The second refrigerant circuit 250 passes through the side of the liquid storage tank 200 facing the evaporator 400 and the side facing the condenser 100. The second refrigerant circuit 250 is isolated from the inner cavity of the liquid storage tank 200. (Refer to...) Figure 7 As shown, the evaporator 400 has a fifth refrigerant inlet 410 and a fifth refrigerant outlet 420 spaced apart on the side facing the liquid storage tank 200. A second heat insulation element may also be provided within the second refrigerant circuit 250, forming a channel for the refrigerant to pass through; for example, the second heat insulation element may be sleeve-shaped. The second heat insulation element can reduce heat exchange between the refrigerant in the second refrigerant circuit 250 and the refrigerant in the liquid storage tank 200. It should be noted that the second heat insulation element is not shown in the figure.

[0072] Therefore, the interface connection relationship of compressor 500, condenser 100, liquid receiver 200, expansion valve 300 and evaporator 400 is as follows: compressor 500 discharge outlet, first refrigerant inlet, condenser channel 173, first refrigerant outlet 140, third refrigerant inlet 210, liquid receiver 200 liquid receiver chamber, third refrigerant outlet 220, second refrigerant inlet 150, subcooling channel 183, second refrigerant outlet 160, fourth refrigerant inlet 230, expansion valve 300 inner cavity, fourth refrigerant outlet 240, fifth refrigerant inlet 410, evaporator 400 inner cavity, fifth refrigerant outlet 420, second refrigerant circuit 250, first refrigerant circuit 113 and compressor 500 air inlet are connected in sequence. To make the thermal management system 1000 more compact, the compressor 500 exhaust outlet and the first refrigerant inlet, the first refrigerant outlet 140 and the third refrigerant inlet 210, the third refrigerant outlet 220 and the second refrigerant inlet 150, the second refrigerant outlet 160 and the fourth refrigerant inlet 230, the fourth refrigerant outlet 240 and the fifth refrigerant inlet 410, the fifth refrigerant outlet 420 and the second refrigerant circuit 250, the first refrigerant circuit 113 and the compressor 500 intake inlet can be directly connected and sealed with a sealing ring to prevent refrigerant leakage and reduce the use of piping, making the thermal management system 1000 more compact.

The vehicle of this utility model adopts the thermal management system 1000 of the above embodiment. The condenser 100 of the thermal management system 1000 has a condensing channel 173 and a first heat exchange channel 174 arranged within a body 110. The body 110 has a first refrigerant circuit 113 penetrating both ends of the body 110, and the first refrigerant circuit 113 is isolated from the condensing channel 173 and the first heat exchange channel 174. The condensing channel 173 is connected to the outlet of the compressor 500, and the first heat exchange channel 174 is externally connected to water. When the high-temperature, high-pressure refrigerant from the compressor 500 enters the condensing channel 173, it can exchange heat with the first heat exchange channel 174, thereby reducing the temperature of the refrigerant and facilitating refrigerant liquefaction. The first refrigerant circuit 113 is used to transport the refrigerant discharged from the evaporator 400 to the air inlet of the compressor 500. By placing the first refrigerant circuit 113 on the main body 110, the use of piping can be reduced, which is beneficial to the compact design of the thermal management system 1000. The first heat insulation element 120 is set in the first refrigerant circuit 113, which can effectively reduce the heat exchange between the refrigerant and the condenser channel 173 and the first heat exchange channel 174 in the first refrigerant circuit 113, thereby ensuring that the temperature of the refrigerant entering the compressor 500 from the first refrigerant circuit 113 is within a suitable range, so as to improve the operating performance of the compressor 500.
