[0026] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any actual relationship or order between these components. The fixed connection or limiting connection described herein, wherein the fixed connection includes welding, bonding, and threaded connection, and the limiting connection includes clamping. Threaded connection can be achieved by bolt connection or screw connection.

[0027] Fluid control components can be applied to thermal management systems, which can be used in household air conditioners, automotive air conditioners, energy storage systems, etc.

[0028] The present application embodiment provides a fluid control component, such as Figure 1-2 As shown, the fluid control component includes a flow channel plate component 1 and a fluid management unit 2. The fluid management unit 2 is fixedly connected or limit-connected to the flow channel plate component 1. The fluid management unit 2 has a channel for circulating medium or a cavity for storing circulating medium. The flow channel plate component 1 has a flow channel 10. The channel or cavity of the fluid management unit 2 is connected to the flow channel 10. The fluid management unit 2 includes a heat exchange device, which includes a condenser 21, an evaporator 22, and an intermediate heat exchanger 23. The fluid management unit 2 also includes a valve component 24, a sensor 25, and a liquid storage device 26. The number of fluid management units 2 can be one or more. In embodiment one, the evaporator 22 includes a first evaporator 221 and a second evaporator 222. The valve component 24 includes a first valve 241, a second valve 242, a third valve 243, and a fourth valve 244. The sensor 25 includes two sensors, which are installed on the flow channel plate assembly 1 to detect the temperature and / or pressure parameters of the refrigerant flowing out of the evaporator 22; in other embodiments, the fluid management unit 2 may include any two or more of the condenser 21, the evaporator 22, the intermediate heat exchanger 23, the valve component 24, the sensor 25, and the liquid storage device 26.

[0029] In this embodiment, the heat exchange device is a plate heat exchanger, each comprising two unconnected first and second channels 201 and 202. The two channels of the condenser 21 and evaporator 22 circulate different media, while the two channels of the intermediate heat exchanger 23 circulate the same media. Specifically, the first channel 201 comprises a first subchannel 2111, a third subchannel, and a fifth subchannel, while the second channel 202 comprises a second subchannel 2112, a fourth subchannel, and a sixth subchannel. In this embodiment, the third, fourth, fifth, and sixth subchannels are not shown. Refrigerant circulates through the first subchannel 2111 of the condenser 21 and the third subchannel of the evaporator 22, while coolant circulates through the second subchannel 2112 of the condenser 21 and the fourth subchannel of the evaporator 22. Refrigerant circulates through the fifth and sixth subchannels of the intermediate heat exchanger 23. The temperature of the refrigerant flowing through the fifth subchannel is generally higher than that of the refrigerant flowing through the sixth subchannel, enabling heat exchange between the media flowing through the fifth and sixth subchannels of the intermediate heat exchanger 23. Valve component 24 is an expansion valve that can throttle the flow channel connected to the channel of valve component 24. Liquid storage device 26 is used to store refrigerant flowing in the system and can separate the liquid phase in the refrigerant, which helps improve the efficiency of valve component 24. In other embodiments, liquid storage device 26 is used to store refrigerant flowing in the system and can separate the gas phase in the refrigerant. The separated gas phase refrigerant can be returned to the compressor, which can reduce the adverse effects of liquid phase refrigerant flowing into the compressor.

[0030] like Figure 1 As shown, a first direction X, a second direction Y and a third direction Z are defined. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. If the third direction Z is set as a vertical direction, the first direction X and the second direction Y are two directions of the horizontal plane. The direction marked with an arrow is designated as a positive direction, and the opposite direction is designated as a negative direction. In this embodiment, the negative direction of the third direction Z is the direction of gravity. The first direction X and the second direction Y can form a first surface S. At least part of the flow channel plate assembly 1 is plate-shaped. In other words, at least part of the flow channel plate assembly 1 extends along the first surface S, and at least part of the flow channel plate assembly 1 has a certain thickness along the third direction Z. As shown in FIG. Figure 1-2 As shown, along the third direction Z flow channel plate assembly 1 includes a first side portion 104 and a second side portion 105 arranged in opposite directions. In other words, the second side portion 105 is located on the opposite side of the first side portion 104, the condenser 21 is installed on the first side portion 104, and the evaporator 22, the valve component 24, and the sensor 25 are installed on the second side portion 105.

[0031] like Figure 3-6As shown, the flow channel plate assembly 1 includes a first plate 101, a second plate 102, and a third plate 103. The third plate 103 includes a first split body 1031 and a second split body 1032, which are separately arranged. The first split body 1031 and the second split body 1032 each include a corresponding first side portion 104. The condenser 21 is mounted on the first side portion 104 of the first split body 1031. The first plate 101 includes a second side portion 105 and a third side portion 106, which are adjacent to each other. The liquid storage device 26 is mounted on the third side portion 106. The second plate 102 includes a fourth side portion 107. The fourth side portion 107 is the portion of the second plate 102 facing the third plate 103 that is not welded to the third plate 103. The fourth side portion 107 is parallel to the second side portion 105. In other embodiments, the liquid storage device 26 can also be mounted on the fourth side portion 107.

[0032] like Figure 3-6 As shown, the first plate 101 and the third plate 103 have flow channel grooves C or flow channel through holes. The first flow channel groove C1 is formed by a depression in the first plate 101, and the second flow channel groove C2 is formed by a depression in the third plate 103. The first plate 101 is located on one side of the second plate 102, and the third plate 103 is located on the opposite side of the second plate 102. The openings of the flow channel grooves of the first plate 101 and the third plate 103 are both facing the second plate 102. At least a portion of the second plate 102 is a flat plate. The second plate 102 can cover the flow channel grooves to form the flow channel 10. The flow channel 10 includes a first layer of flow channels and a second layer of flow channels. The second plate 102 is provided with a connecting hole, defining the flow channel formed by the first plate 101 and the second plate 102 as the first layer of flow channels, and the flow channel 10 formed by the third plate 103 and the second plate 102 as the second layer of flow channels. With the help of the connecting hole, part of the first layer of flow channels can be connected with part of the second layer of flow channels. It should be noted that the first plate 101 includes a flow through hole formed separately thereon. This flow through hole is part of the flow channel 10 and constitutes the first-layer flow channel. Similarly, the third plate 103 also includes another flow through hole formed separately thereon, which is also part of the flow channel 10 and constitutes the second-layer flow channel. The three-layer plate structure makes the flow channel plate assembly 1 compact and easy to manufacture.

[0033] The flow channel 10 includes a first flow channel 11 and a second flow channel 12. The first flow channel 11 can circulate refrigerant, and the second flow channel 12 can circulate coolant. In this embodiment, the first layer of flow channels includes a portion of the first flow channel 11 and a portion of the second flow channel 12. Similarly, the second layer of flow channels includes a portion of the first flow channel 11 and a portion of the second flow channel 12. In other embodiments, the first layer of flow channels may be arranged with the first flow channel 11, and the second layer of flow channels may be arranged with the second flow channel 12. The flow channel 10 of the flow channel plate assembly 1 includes the first flow channel 11 and the second flow channel 12. Through this arrangement, the first channels 201 and the second channels 202 corresponding to the condenser 21 and the evaporator 22 can all be connected to the flow channel 10 of the flow channel plate assembly 1. In this way, after connecting to the corresponding connection portion 15 of the flow channel plate assembly 1, the connection requirements of the two channels can be met. The other end of the second flow channel 12 is connected to the coolant management module, which eliminates the need for a separate connecting pipeline to the coolant management module.

[0034] like Figure 6-7As shown, the condenser 21 and the evaporator 22 both include corresponding first matching parts and second matching parts. Specifically, the condenser 21 includes a first matching part 2101 of the condenser with one inlet and one outlet, and a second matching part 2102 of the condenser with one inlet and one outlet. The first sub-channel 2111 of the condenser 21 has an opening in the first matching part 2101 of the condenser, and the second sub-channel 2112 has an opening in the second matching part 2102 of the condenser; the evaporator 22 includes a first matching part 2201 of the evaporator with one inlet and one outlet, and a second matching part 2202 of the evaporator with one inlet and one outlet. The third sub-channel of the evaporator 22 has an opening in the first matching part 2201 of the evaporator, and the fourth sub-channel of the evaporator 22 has an opening in the second matching part 2202 of the evaporator. The corresponding flow channel plate assembly 1 includes a connecting portion 15, which includes a first connecting portion 151 and a second connecting portion 152. The first flow channel 11 has an opening in the first connecting portion 151, and the second flow channel 12 has an opening in the second connecting portion 152. The flow channel 10 can communicate with the channel of the heat exchange device through the opening of the connecting portion 15. There are multiple first connecting portions 151, and multiple second connecting portions 152. Specifically, the condenser first connecting portion 1511 corresponds to the condenser first mating portion 2101, the evaporator first connecting portion 1512 corresponds to the evaporator first mating portion 2201, the condenser second connecting portion 1521 corresponds to the condenser second mating portion 2102, and the evaporator second connecting portion 1522 corresponds to the evaporator second mating portion 2202. In this embodiment, at least a portion of the first mating portion is located in the cavity of the first connecting portion 151. The first mating portion and the first connecting portion 151 are radially sealed. The second mating portion and the second connecting portion 152 are arranged opposite each other, and the second mating portion and the second connecting portion 152 are end-face sealed. In this embodiment, there are two evaporators 22, corresponding to four first evaporator connection portions 1512 and four second evaporator connection portions 1522. In this embodiment, the connection portions 15 are located on the first plate 101 and the third plate 103, respectively. The opening of the connection portion 15 located on the first plate 101 faces oppositely to the opening of the flow channel groove of the first plate 101, and the opening of the connection portion 15 located on the third plate 103 faces oppositely to the opening of the flow channel groove of the third plate 103.

[0035] The interface portion 13 of the manifold plate assembly 1 includes a coolant interface portion 132. One end of the second flow channel 12 opens at the second connection portion 152, and the other end of the second flow channel 12 opens at the coolant interface portion 132. The coolant interface portion 132 is used to connect to the coolant management module. To shorten the flow of the second flow channel 12 connecting the second connection portion 152 and the coolant interface portion 132, two evaporators 22 are arranged in a row, with the first evaporator 221 closer to the edge of the manifold plate assembly 1 than the second evaporator 222. For each evaporator 22, the evaporator's first connection portion 1512 is closer to the edge of the manifold plate assembly 1 than the evaporator's first connection portion 1512. The valve component 24 is arranged on the opposite side of the evaporator 22 from the coolant interface portion 132. This ensures that the refrigerant, after throttling by the valve component 24, flows to the more distant first evaporator 221 over a longer flow path and needs to intersect with the portion of the flow channel 10 connecting the second evaporator 222.

[0036] The interface portion 13 of the flow channel plate assembly 1 also includes a refrigerant interface portion 131, which includes an inlet portion 1311, a first outlet portion 1312, and a second outlet portion 1313. The opening of the inlet portion 1311 communicates with the outlet of the compressor, the opening of the first outlet portion 1312 communicates with the first inlet of the compressor, and the opening of the second outlet portion 1313 communicates with the second inlet of the compressor. Specifically, the second outlet portion 1313 is located on the mounting plate of the flow channel plate assembly 1, and the intermediate heat exchanger 23 is fixedly connected to the first plate 101 of the flow channel plate assembly 1 via the mounting plate. The mounting plate, similar to the second plate 102, includes three communication holes. One side of the communication hole connects to the channel of the intermediate heat exchanger 23, and the other side connects to the opening of the corresponding connection portion on the first plate 101. The mounting plate also includes a bent communication hole. The opening of the bent communication hole toward the intermediate heat exchanger 23 connects to the channel of the intermediate heat exchanger 23. The other opening of the bent communication hole, namely the opening of the second outlet portion 1313, faces the extension direction of the first plate 101, which facilitates connection with the pipe assembly. The inlet portion 1311 and the first outlet portion 1312 are both located on the circumferential side of the second split 1032 of the third plate 103, with the opening facing the extension direction of the second split 1032, facilitating the installation of the pipe assembly from the side.

[0037] The flow channel plate assembly 1 includes a valve mounting portion 14. In this embodiment, the valve mounting portion 14 is located on the first plate 101. Specifically, at least a portion of the valve component 24 is located in the corresponding cavity of the valve mounting portion 14, and the cavity of the valve mounting portion 14 is connected to the first flow channel 11. The first valve 241 corresponds to the first valve mounting portion 141, the second valve 242 corresponds to the second valve mounting portion 142, the third valve 243 corresponds to the third valve mounting portion 143, and the fourth valve 244 corresponds to the fourth valve mounting portion 144. The opening of the valve mounting portion 14 faces opposite to the opening of the flow channel groove of the first plate 101. For the first plate 101, one side is used to form the flow channel 10, and the other side is used to mount the valve component 24.

[0038] like Figure 3-10 As shown, in this embodiment, the first flow channel 11 includes a first branch flow channel 111, a second branch flow channel 112, a third branch flow channel 113, a fourth branch flow channel 114, a fifth branch flow channel 115, a sixth branch flow channel 116, a seventh branch flow channel 117, an eighth branch flow channel 118, and a ninth branch flow channel 119. Figure 7 The installation positions of the evaporator 22 and the intermediate heat exchanger 23 on the other side of the first plate 101 are shown in dashed-line boxes.

[0039] The refrigerant flowing out of the compressor flows into the first branch channel 111 through the opening of the inlet portion 1311. A portion flows into the first sub-channel 2111 of the condenser 21, and another portion flows to the fourth valve 244. After dissipating heat in the condenser 21, a portion of the refrigerant flows back to the second branch channel 112 and enters the liquid storage device 26. A portion of the refrigerant flowing out of the liquid storage device 26 enters the fifth sub-channel of the intermediate heat exchanger 23, and another portion flows to the third valve 243. After throttling and expansion by the third valve 243, it flows into the sixth sub-channel of the intermediate heat exchanger 23. The refrigerant flowing out of the sixth sub-channel flows back to the compressor through the opening of the second outlet portion 1313, while the refrigerant flowing out of the fifth sub-channel flows to the first valve 241 and the second valve 242. The refrigerant flowing into the fourth valve 244, after throttling and expansion, can flow back to the compressor 3 through the opening of the first outlet portion 1312. The third valve 243 and the fourth valve 244 can adjust the parameters of the refrigerant after throttling and expansion according to the different opening degrees of the valve core assembly, thereby adjusting the operation of the compressor 3 or the operation of the thermal management system. The intermediate heat exchanger 23 is also provided to adjust the operation of the thermal management system, so that the thermal management system can be better applied in different usage environments. The refrigerant flowing into the first valve 241 and the second valve 242 is divided into two paths. One part passes through the throttling expansion of the first valve 241 and flows to the third sub-channel of the first evaporator 221. It flows through the third sub-channel to absorb heat and then returns to the eighth branch channel 118. The other part passes through the throttling expansion of the second valve 242 and flows to the third sub-channel of the second evaporator 222. It flows through the third sub-channel to absorb heat and then returns to the sixth branch channel 116. The two refrigerant flows are mixed in the ninth branch channel 119 and then return to the compressor through the opening of the first outlet portion 1312.

[0040] Specifically, the first branch channel 111 includes a first section 1111 and a second section 1112. The first section 1111 is a second layer channel, and the second section 1112 is a first layer channel. The first section 1111 and the second section 1112 are connected through a first connecting hole 1110. Figure 9 The second section 1112 shown is a through-hole flow channel on the first plate 101. The through-hole flow channel can be machined or cast, and any process holes can be sealed with a plug. The second section 1112 communicates with the cavity of the fourth valve mounting portion 144. The fourth valve 244 can open, close, or throttle the connection between the second section 1112 and the ninth branch flow channel 119. The first section 1111 communicates with the opening of one of the condenser first connection portions 1511. The first section 1111 also communicates with the opening of the inlet portion 1311.

[0041] The second branch flow channel 112 includes a third section 1121 and a fourth section 1122. The third section 1121 is a second-layer flow channel, and the fourth section 1122 is a first-layer flow channel. The third section 1121 and the fourth section 1122 are connected through the second communication hole 1120.

[0042] The third branch flow channel 113 includes a fifth section 1131 and a sixth section 1132. The third branch flow channel 113 is a first-layer flow channel. The fifth section 1131 can communicate with the cavity of the liquid storage device 26, and the fifth section 1131 can communicate with the fifth sub-channel of the intermediate heat exchanger 23. The other end of the fifth sub-channel is connected to the fourth branch flow channel 114. The sixth section 1132 can communicate with the sixth sub-channel of the intermediate heat exchanger 23. The sixth sub-channel is connected to the opening of the second outlet portion 1313 on the peripheral side of the mounting plate. The fifth section 1131 and the sixth section 1132 are both connected to the cavity of the third valve mounting portion 143. The third valve 243 can open, close, or throttle the connection between the fifth section 1131 and the sixth section 1132.

[0043] The fourth branch channel 114 is in communication with the cavity of the first valve mounting portion 141 and the cavity of the second valve mounting portion 142, respectively. The first valve 241 is capable of opening, closing, or throttling the communication between the fourth branch channel 114 and the fifth branch channel 115. The fifth branch channel 115 is in communication with the opening of the first connection portion 1512 of one of the second evaporators 222. One end of the sixth branch channel 116 is in communication with the opening of the first connection portion 1512 of the other evaporator 222. The other end of the sixth branch channel 116 is in communication with the ninth branch channel 119 of the second layer of the channel through the third communication hole 1160.

[0044] The seventh branch channel 117 includes a seventh section 1171, an eighth section 1172, and a ninth section 1173. The seventh and ninth sections 1171 and 1173 form the first-layer channel, while the eighth section 1172 forms the second-layer channel. The seventh section 1171 is a through-hole channel in the first plate 101 and communicates with the second valve mounting portion 142. The second valve 242 can open, close, or throttle the connection between the fourth branch channel 114 and the seventh section 1171. The seventh section 1171 communicates with the eighth section 1172 via a fourth communication hole 11701, while the eighth section 1172 communicates with the ninth section 1173 via a fifth communication hole 11702.

There are six coolant interface portions 132, and the openings of the six coolant interface portions 132 are connected to the eleventh branch flow channel 121, the twelfth branch flow channel 122, the thirteenth branch flow channel 123, the fourteenth branch flow channel 124, the fifteenth branch flow channel 125, and the sixteenth branch flow channel 126 in a one-to-one correspondence. In this embodiment, the coolant interface portions 132 are located on the first plate 101, and the openings face the positive direction of the third direction Z.

[0046] The other ends of the eleventh branch channel 121 and the twelfth branch channel 122 are respectively in communication with the opening of the condenser second connection portion 1521 of the condenser 21, and further communicate with the second sub-channel 2112 of the condenser 21. The other ends of the thirteenth branch channel 123 and the sixteenth branch channel 126 are respectively in communication with the opening of the evaporator second connection portion 1522 of the first evaporator 221, and further communicate with the fourth sub-channel of the first evaporator 221. The other ends of the fourteenth branch channel 124 and the fifteenth branch channel 125 are respectively in communication with the opening of the evaporator second connection portion 1522 of the second evaporator 222, and further communicate with the fourth sub-channel of the second evaporator 222.

[0047] Specifically, the eleventh branch channel 121 includes an eleventh section 1211 and a twelfth section 1212, which are connected via the seventh connecting hole 1210 of the second plate 102. The twelfth branch channel 122 includes a thirteenth section 1221 and a fourteenth section 1222, which are connected via the eighth connecting hole 1220 of the second plate 102. The eleventh section 1211 and the thirteenth section 1221 are second-layer flow channels, while the twelfth section 1212 and the fourteenth section 1222 are first-layer flow channels. The thirteenth branch channel 123, the fourteenth branch channel 124, the fifteenth branch channel 125, and the sixteenth branch channel 126 are all first-layer flow channels.

[0048] The flow channel plate assembly 1 includes a heat exchange portion 16, and the flow channel 10 includes a first heat exchange channel A and a second heat exchange channel B. At least a portion of the first heat exchange channel A is located on one side of the heat exchange portion 16, and at least a portion of the second heat exchange channel B is located on the opposite side of the heat exchange portion 16. The heat exchange portion 16 includes a wall forming the first heat exchange channel A and a wall forming the second heat exchange channel B. Part of the wall of the first heat exchange channel A and part of the wall of the second heat exchange channel B are formed on the same structural component, the heat exchange portion 16. The heat exchange portion 16 allows the medium in the flow channel 10 located on both sides of the heat exchange portion 16 to exchange heat. In this embodiment, the material of the flow channel plate assembly 1 is metal, such as aluminum, which has good thermal conductivity. In other embodiments, the material of the flow channel plate assembly 1 can also be other heat-transfer materials, such as composite materials, polymer materials, etc. The flow channel plate assembly 1 is provided with the first heat exchange channel A and the second heat exchange channel B capable of heat exchange, which helps to improve the heat exchange performance of the heat exchange device, and thus improve the heat exchange performance of the fluid control component. In other words, when the heat exchange capacity of the heat exchange device is required to be certain, the heat exchange between the flow channels 10 of the flow channel plate assembly 1 can share a portion of the heat exchange capacity of the previous heat exchange device, which is conducive to reducing the performance indicators of the heat exchange device and also conducive to the miniaturization of the heat exchange device. For example, the previous heat exchange device was a laminated plate heat exchanger, which met the heat exchange capacity requirement by increasing the height of the laminate. When a portion of the heat exchange capacity is borne by the flow channel plate assembly, it is conducive to reducing the height of the laminate of the heat exchange device, which is further conducive to the miniaturization of the heat exchange device. Heat exchange devices with other structures also have this effect, which will not be elaborated here.

[0049] In this embodiment, the heat exchange portion 16 includes a first heat exchange portion 161, the first heat exchange channel A includes a first sub-heat exchange channel A1, and the second heat exchange channel B includes a second sub-heat exchange channel B1. As described above, the channel 10 connecting the first evaporator 221 and the channel 10 connecting the second evaporator 222 are arranged crosswise. The reasonable arrangement of the channel 10 is conducive to improving the heat exchange performance of the evaporator 22. Figure 6 and Figure 10As shown, the eighth segment 1172 of the first flow channel 11 intersects the fourteenth branch flow channel 124 of the second flow channel 12. The orthographic projection of the intersection of the eighth segment 1172 and the fourteenth branch flow channel 124 on the second plate 102 corresponds to the first heat exchange portion 161. At least a portion of the eighth segment 1172 of the first flow channel 11 is located on one side of the first heat exchange portion 161, while at least a portion of the fourteenth branch flow channel 124 of the second flow channel 12 is located on the opposite side of the first heat exchange portion 161. The temperature of the medium in the eighth segment 1172 is lower than that of the medium in the fourteenth branch flow channel 124, enabling heat exchange between the two flow channels. The eighth segment 1172 communicates with the third sub-channel of the first evaporator 221, while the fourteenth branch flow channel 124 communicates with the fourth sub-channel of the second evaporator 222. In other embodiments, the flow channels 10 located on either side of the first heat exchange portion 161 can also be two flow channels 10 connected to the same evaporator 22. In this embodiment, the eighth section 1172 is the first sub-heat exchange channel A1, and the fourteenth branch channel 124 is the second sub-heat exchange channel B1.

[0050] In other embodiments, Figure 14 As shown, the first branch flow channel 111 of the first flow channel 11 and the eleventh branch flow channel 121 of the second flow channel 12 are first-layer flow channels, the flow channel groove of the first plate 101 and the second plate 102 can form at least part of the first branch flow channel 111, and the flow channel groove of the first plate 101 and the second plate 102 can form at least part of the eleventh branch flow channel 121. The first plate 101 includes a fifth heat exchange part 165, at least part of the first branch flow channel 111 is located on one side of the fifth heat exchange part 165, and at least part of the eleventh branch flow channel 121 is located on the other side of the fifth heat exchange part 165. The first branch flow channel 111 is connected to the first sub-channel 2111 of the condenser 21, and the eleventh branch flow channel 121 can be connected to the second sub-channel 2112 of the condenser 21. The temperature of the medium in the first branch flow channel 111 is higher than the temperature of the medium in the eleventh branch flow channel 121. The heat exchange between the medium in the first branch flow channel 111 and the medium in the second branch flow channel 121 is beneficial to improving the heat exchange efficiency of the condenser 21. The first heat exchange channel A includes a third sub-heat exchange channel, and the second heat exchange channel B includes a fourth sub-heat exchange channel. The first branch channel 111 is the third sub-heat exchange channel A2, and the eleventh branch channel 121 is the fourth sub-heat exchange channel B2.

[0051] like Figure 6-7As shown, the heat exchange portion 16 includes a second heat exchange portion 162. The fifth segment 1131 can communicate with the fifth sub-channel of the intermediate heat exchanger 23, and the sixth segment 1132 can communicate with the sixth sub-channel of the intermediate heat exchanger 23. The media flowing through the fifth and sixth sub-channels of the intermediate heat exchanger 23 can exchange heat. On the first plate 101, along the extension direction of the first plate 101, at least a portion of the fifth segment 1131 is located adjacent to the sixth segment 1132. The second heat exchange portion 162 is a wall located between the fifth and sixth segments 1131, 1132. The same medium, such as refrigerant, flows through the fifth and sixth segments 1131, 1132, but the temperatures of the media flowing through the fifth and sixth segments 1131, 1132 are different. The heat exchange between the media in the fifth and sixth segments 1131, 1132 can improve the efficiency of the intermediate heat exchanger 23. The fifth segment 1131 is the first heat exchange channel A, and the sixth segment 1132 is the second heat exchange channel B. In other embodiments, coolant can flow through the two channels of the intermediate heat exchanger 23, and coolant flows through the corresponding first heat exchange channel A and the second heat exchange channel B. The heat exchange of the medium in the first heat exchange channel A and the second heat exchange channel B can improve the heat exchange efficiency of the intermediate heat exchanger 23 through which the coolant flows. Such an intermediate heat exchanger 23 is also called a water-to-water heat exchanger.

[0052] In other embodiments, Figure 11 and Figure 12 As shown, the fifth section 1131 and the sixth section 1132 are not located on the same structural member. The flow channel groove of the first plate 101 and the second plate 102 form at least a portion of the fifth section 1131, and the flow channel groove of the third plate 103 and the second plate 102 form at least a portion of the sixth section 1131. The second heat exchange portion 162 is part of the second plate 102. The fifth section 1131 includes the first heat exchange section A3, and the sixth section 1132 includes the second heat exchange section B3. Figure 12 The dotted box in FIG shows the approximate range of the first heat exchange section A3, the second heat exchange section B3 and the second heat exchange portion 162, as shown in FIG. Figure 12 The first heat exchange section A3, second heat exchange section B3, and second heat exchange portion 162 extend in substantially the same direction. The second heat exchange portion 162 is the portion of the structure corresponding to the orthographic projection of the first heat exchange section A3 on the second plate 102. The first heat exchange section A3, second heat exchange section B3, and second heat exchange portion 162 extend in substantially the same direction, increasing the heat exchange surface and further improving heat exchange performance. It should be noted that the term "substantially the same extension direction" means that the angle between the axes of extension is within the range of 0-10 degrees.

[0053] like Figure 6-7As shown, the heat exchange section 16 includes a third heat exchange section 163. The outlet flow channel of the evaporator 22 includes a sixth branch flow channel 116 and an eighth branch flow channel 118, which are mixed and then flow back to the compressor. The fourth section 1122 is the outlet flow channel of the condenser 21 and flows to the liquid storage device 26. At least part of the sixth branch flow channel 116 and at least part of the eighth branch flow channel 118 are located on one side of the third heat exchange section 163, and at least part of the fourth section 1122 is located on the other side of the third heat exchange section 163. The medium in the sixth branch flow channel 116 and the medium in the eighth branch flow channel 118 can respectively absorb the heat of the medium in the fourth section 1122, which is beneficial to increase the superheat of the refrigerant flowing back to the compressor and improve the efficiency of the compressor. In other words, it can improve the heat exchange efficiency of the fluid control assembly. This setting is equivalent to building a heat exchanger into the flow channel plate assembly 1, while reducing the plate heat exchanger installed on the side of the flow channel plate assembly for heat exchange, making the flow channel plate assembly 1 more functional. The sixth branch channel 116 and the eighth branch channel 118 are the first heat exchange channel A, and the fourth section 1122 of the first channel 11 is the second heat exchange channel B.

[0054] In other embodiments, Figure 13 As shown, the first layer of flow channels includes a ninth branch flow channel 119, and the second layer of flow channels includes a fourth segment 1122. The ninth branch flow channel 119 is connected to the outlet of the evaporator 22 and can flow back to the compressor. The fourth segment 1122 is the outlet flow channel of the condenser 21 and flows to the liquid storage device 26. The ninth branch flow channel 119 and the fourth segment 1122 can exchange heat through the fourth heat exchange portion 164, which is part of the second plate 102. The ninth branch flow channel 119 is the first heat exchange flow channel A, and the fourth segment 1122 of the first flow channel 11 belongs to the second heat exchange flow channel B.
