[0028] 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.

[0029] The fluid control component can be applied to a thermal management system, which can be used in household air conditioners, automotive air conditioners, energy storage systems, etc. This application will be introduced using automotive air conditioners as an example.

[0030] Example 1:

[0031] The present application embodiment provides a fluid control component, such as Figure 1-9 As shown, the fluid control component includes a reagent side component, and the reagent side 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 condenser 21, an evaporator 22, a heat exchanger 23, 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, and there are five sensors 25, two of which are installed on the flow channel plate assembly 1 for detecting the temperature and / or pressure parameters of the refrigerant flowing out of the evaporator 22, and the other three are installed on the pipe assembly 4 for respectively detecting the temperature and / or pressure parameters of the refrigerant flowing in each pipeline; in other embodiments, the fluid management unit 2 may include any two or more of the condenser 21, the evaporator 22, the heat exchanger 23, the valve component 24, the sensor 25, and the liquid storage device 26.

[0032] In this embodiment, the condenser 21, evaporator 22, and heat exchanger 23 are all plate-type heat exchangers, each including two channels. The two channels of the condenser 21 and evaporator 22 circulate different media, while the two channels of the heat exchanger 23 circulate the same medium. Specifically, the first channel 2111 of the condenser 21 and the third channel 2211 of the evaporator 22 circulate refrigerant, the second channel 2112 of the condenser 21 and the fourth channel 2212 of the evaporator 22 circulate coolant, and the fifth and sixth channels of the heat exchanger 23 both circulate refrigerant. The valve component 24 is an expansion valve capable of throttling the flow channel connected to the channel of the valve component 24. In other embodiments, the valve component 24 may also include an on-off valve. The liquid storage device 26 is used to store the refrigerant flowing in the system and is capable of separating the liquid phase in the refrigerant, which helps improve the efficiency of the valve component 24.

[0033] The fluid control assembly also includes a compression unit 3, which is connected to the agent-side assembly via a pipe assembly 4. Specifically, the pipe assembly 4 is bolted to the corresponding components via pressure plates provided at both ends of the pipe. The compression unit 3 and the agent-side assembly are fixedly connected to the mounting bracket 5. A shock-absorbing unit (not shown) is provided between the compression unit 3 and the mounting bracket 5, and between the agent-side assembly and the mounting bracket 5. The shock-absorbing unit can reduce the impact of vibration of the compression unit 3 during operation on the agent-side assembly. In addition, a shock-absorbing unit is provided at one end of the mounting bracket 5 where it is mounted to the vehicle frame to further reduce the impact of vibration of the compression unit 3.

[0034] The refrigerant flowing out of the compression unit 3 flows through the first pipe 41 into the flow channel 10 of the flow channel plate assembly 1. Part of it flows into the first channel 2111 of the condenser 21, and the other part flows to the fourth valve 244. After dissipating heat in the condenser 21, part of the refrigerant flows back to the flow channel 10 and enters the liquid storage device 26. Part of the refrigerant flowing out of the liquid storage device 26 enters the fifth channel of the heat exchanger 23, and the other part flows to the third valve 243. After throttling and expansion by the third valve 243, it flows to the sixth channel of the heat exchanger 23. The refrigerant flowing out of the sixth channel flows back to the compression unit 3, and the refrigerant flowing out of the fifth channel flows to the first valve 241 and the second valve 242. The refrigerant flowing into the fourth valve 244 can then flow back to the compression unit 3 after throttling and expansion. 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 regulating the operation of the compression unit 3 or the thermal management system. The 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 is throttled and expanded by the first valve 241 and flows into the third channel 2211 of the first evaporator 221. It flows through the third channel 2211 to absorb heat and then flows back to the flow channel 10. The other part is throttled and expanded by the second valve 242 and flows into the third channel 2211 of the second evaporator 222. It flows through the third channel 2211 to absorb heat and then flows back to the flow channel 10. The two refrigerants are mixed in the flow channel 10 and then flow back to the compression unit 3.

[0035] 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 other 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. At least part of the flow channel plate assembly 1 has a certain thickness along the third direction Z. The first surface S is perpendicular to the thickness direction of the flow channel plate assembly 1. As shown Figure 1-9As shown, along the third direction Z, the flow channel plate assembly 1 includes a first side portion 104 and a second side portion 105 disposed opposite each other. In other words, the second side portion 105 and the first side portion 104 are located on opposite sides of the flow channel plate assembly 1. The condenser 21 is fixedly connected or position-limited to the first side portion 104, the evaporator 22 is fixedly connected or position-limited to the second side portion 105, and the valve component 24 is fixedly connected or position-limited to the second side portion 105. The condenser 21 and the evaporator 22 are respectively installed on either side of the flow channel plate assembly 1. This fully utilizes the installation space on both sides of the flow channel plate assembly 1, making the fluid control assembly compact. In addition, the flow channel plate assembly 1 is located between the condenser 21 and the evaporator 22, which is beneficial to the integrated flow channel arrangement of the flow channel plate assembly 1 and the compact structure of the fluid control assembly. The valve component 24 and the evaporator 22 are mounted on the same side of the flow channel plate assembly 1, which facilitates shortening the flow channel 10 connecting the valve component 24 and the evaporator 22. This contributes to a compact structure while reducing harmful heat transfer between the refrigerant flowing out of the valve component 24 and entering the evaporator 22, thereby improving the efficiency of the evaporator 22. Along the thickness direction of the flow channel plate assembly 1, or the third direction Z, the projections of the condenser 21 and the evaporator 22 on the first surface S at least partially overlap. This overlapping arrangement facilitates space utilization.

[0036] In this embodiment, the flow channel plate assembly 1 includes a first plate 101, a second plate 102, and a third plate 103. The first plate 101 and the third plate 103 have flow channel grooves or flow channel through holes. The first plate 101 is located on one side of the second plate 102, and the third plate 103 is located on the other side opposite the second plate 102. The openings of the flow channel grooves are all facing the second plate 102. The second plate 102 can cover the flow channel grooves to form a 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, which defines 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 on the first plate 101, the flow through hole is part of the flow channel 10, and the flow through hole of the first plate 101 is the first layer flow channel. Similarly, the third plate 103 also includes another flow through hole formed separately on the third plate 103, which is also part of the flow channel 10, and the flow through hole of the third plate 103 is the second layer flow channel.

[0037] 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. This arrangement allows the first channel 2111, the second channel 2112, the third channel 2211, and the fourth channel 2212 of the plate heat exchanger to be connected to the flow channels of the flow channel plate assembly 1. In this way, the connection requirements of the two channels can be met by connecting the water-cooled plate heat exchanger to the corresponding connection portion 15 of the flow channel plate assembly 1. The other end of the second flow channel 12 is connected to the coolant management module, eliminating the need for a separate connecting pipeline to the coolant management module. It should be noted that the coolant management module usually includes thermal management components such as pumps and valves, and the coolant circuit in the coolant pipeline module is controlled by the pumps and valves to meet the thermal management needs of the vehicle. Usually, the refrigerant interface of the water-cooled plate heat exchanger is connected to the interface corresponding to the fluid control component, and the coolant interface of the water-cooled plate heat exchanger is connected to the interface corresponding to the coolant management module. The plate heat exchangers are respectively installed on different bearings, and the installation structure is unstable. In addition, the coolant management module can also be fixedly connected to the fluid control component. In this way, there will be installation errors between the three, which is not conducive to the installation and operation of the water-cooled plate heat exchanger. In this embodiment, the water-cooled plate heat exchanger is installed with the same structural component, which improves the installation stability of the water-cooled plate heat exchanger. The water-cooled plate heat exchanger mentioned here is generally a plate heat exchanger that includes two medium channels: refrigerant and coolant. In other embodiments, the pump, valve and other thermal management components of the coolant management module can also be centrally arranged in the flow channel plate assembly 1 of the fluid control assembly. The pump, valve and other thermal management components can adjust the connectivity or flow state of at least part of the second flow channel 12.

[0038] like Figure 6-7As shown, the condenser 21 and the evaporator 22 include respective corresponding mating parts 20. Specifically, the mating part 20 includes a refrigerant mating part 201 and a coolant mating part 202. Specifically, the condenser 21 includes a first mating part 2101 and a second mating part 2102, respectively. The first channel 2111 of the condenser 21 has an opening in the first mating part 2101, and the second channel 2112 has an opening in the second mating part 2102. The evaporator 22 includes a first mating part 2201 and a second mating part 2202, respectively. The third channel 2211 of the evaporator 22 has an opening in the first mating part 2201, and the fourth channel 2212 of the evaporator 22 has an opening in the second mating part 2202. The corresponding flow channel plate assembly 1 includes a connecting portion 15. The flow channel 10 has an opening in the connecting portion 15. The connecting portion 15 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 passage of the heat exchanger through the opening of the connecting portion 15. The connecting portion 15 is sealed with the mating portion 20. In this embodiment, at least a portion of the refrigerant mating portion 201 is located in the cavity of the first connecting portion 151. The refrigerant mating portion 201 and the first connecting portion 151 are radially sealed. The coolant mating portion 202 is arranged opposite the second connecting portion 152, and the coolant mating portion 202 and the second connecting portion 152 are end-face sealed. There are multiple first connecting portions 151 and multiple second connecting portions 152. Specifically, the first connection part 1511 of the condenser corresponds to the first matching part 2101 of the condenser, the first connection part 1512 of the evaporator corresponds to the first matching part 2201 of the evaporator, the second connection part 1521 of the condenser corresponds to the second matching part 2102 of the condenser, and the second connection part 1522 of the evaporator corresponds to the second matching part 2202 of the evaporator.

[0039] The coolant matching portion 202 is closer to the side of the flow channel plate assembly 1 than the refrigerant matching portion 201. Figure 7 As shown, along the first direction X, the condenser's second mating portion 2102 is closer to the side of the manifold plate assembly 1 than the condenser's first mating portion 2101, and the evaporator's second mating portion 2202 is closer to the side of the manifold plate assembly 1 than the evaporator's first mating portion 2201. This arrangement facilitates the centralized arrangement of the first flow channels 11 connected to the refrigerant mating portion 201 and reserves installation space for other components connected to the coolant mating portion 202. In this embodiment, the coolant mating portion 202 is connected to the second connecting portion 152 of the manifold plate assembly 1. In other embodiments, the coolant mating portion 202 can also be connected directly to the coolant management module or via a pipeline.

[0040] The interface portion 13 of the manifold plate assembly 1 includes a coolant interface portion 132. One end of the second manifold 12 has an opening at the second connection portion 152, and the other end of the second manifold 12 has an opening at the coolant interface portion 132. The coolant interface portion 132 is used to connect to the coolant management module. The arrangement of the condenser 21 and the evaporator 22 allows the coolant matching portion 202 to be located near the side of the manifold plate assembly 1, which is beneficial for the arrangement of the second manifold 12, making the flow of the second manifold 12 shorter and facilitating the centralized arrangement of the coolant interface portion 132 on the side of the manifold plate assembly 1. Relatively speaking, the first manifold 11 can also be integrated and arranged on the other side of the manifold plate assembly 1. The interface portion 13 of the manifold 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 is connected to the outlet 31 of the compression unit 3 through the first tube 41, the opening of the first outlet portion 1312 is connected to the first inlet 32 of the compression unit through the second tube 42, and the opening of the second outlet portion 1313 is connected to the second inlet 33 of the compression unit 3 through the third tube 43. Specifically, the second outlet portion 1313 is located on the mounting plate of the flow channel plate assembly 1, and the heat exchanger 23 is fixedly connected to the first plate 101 of the flow channel plate assembly 1 through the mounting plate. The mounting plate is similar to the second plate 102 and includes three connecting holes. One side of the connecting hole is connected to the channel of the heat exchanger 23, and the other side of the connecting hole is connected to the opening of the corresponding connecting portion 15 on the first plate 101. The mounting plate also includes a bent connecting hole. The opening of the bent connecting hole toward the heat exchanger 23 is connected to the channel of the heat exchanger 23. The other opening of the bent connecting hole, namely the opening of the second outlet portion 1313, is oriented in the extension direction of the first plate 101, thereby facilitating connection with the tube assembly 4. The inlet portion 1311 and the first outlet portion 1312 are both located on the peripheral side of the second split body 1032 of the third plate 103 , with the openings facing the extension direction of the second split body 1032 , so as to facilitate the installation of the tube assembly 4 from the side.

[0041] In this embodiment, the evaporator 22 includes a first evaporator 221 and a second evaporator 222. The second evaporator mating portion 2202 of the evaporator 22 is arranged along the long side of the plate of the evaporator 22. In other words, when the long side of the evaporator 22 is arranged along the second direction Y, the second evaporator mating portion 2202 is conveniently arranged along the edge of the flow channel plate assembly 1. If there are two evaporators 22, if both evaporators 22 are arranged close to the edge, the evaporators 22 occupy a large space, which is not conducive to the compact arrangement of the fluid control assembly. In this embodiment, the first evaporator 221 and the second evaporator 222 are arranged along the first direction X. Such an arrangement is conducive to the compact arrangement of the fluid control component. The second evaporator 222 is located in the middle position of the flow channel plate assembly 1 relative to the first evaporator 221, away from the side of the flow channel plate assembly 1. Such an arrangement makes the second flow channel 12 corresponding to the evaporator second matching part 2202 of the second evaporator 222 have a longer flow path. In this embodiment, the second flow channel 12 corresponding to the evaporator second matching part 2202 of the second evaporator 222 passes through directly below the first evaporator 221, thereby shortening the arrangement of these second flow channels 12 as much as possible.

[0042] The refrigerant flowing out of the compression unit 3 and circulating before condensation in the condenser 21 is defined as a high-temperature refrigerant, the refrigerant circulating after condensation in the condenser 21 and before throttling by the valve component 24 is defined as a medium-temperature refrigerant, and the refrigerant flowing through the evaporator 22 and returning to the compression unit 3 after throttling by the valve component 24 is defined as a low-temperature refrigerant. The corresponding high-temperature flow channel is the high-temperature flow channel, the medium-temperature flow channel is the medium-temperature flow channel, and the low-temperature flow channel is the low-temperature flow channel. It should be noted that there is no specific temperature limit for the high temperature, medium temperature and low temperature here. High temperature means a higher temperature relative to the medium-temperature refrigerant, and medium temperature means a higher temperature relative to the low-temperature refrigerant.

[0043] The condenser 21 is mounted on the first side portion 104. The third plate 103 includes a first split body 1031 and a second split body 1032. 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 second layer of flow channels formed by the first split body 1031 and the second plate 102 include a high-temperature flow channel. The evaporator 22 and the valve component 24 are mounted on the second side portion 105. The first plate 101 includes the second side portion 105. The first layer of flow channels formed by the first plate 101 and the second plate 102 include a medium-temperature flow channel and a low-temperature flow channel. The first plate 101 includes a third side portion 106, and the second plate 102 includes a fourth side portion 107. The fourth side portion 107 is a portion of the second plate 102 facing the third plate 103 that is not welded to the third plate 103. The third side portion 106 is connected to the second side portion 105 and the fourth side portion 107 respectively. The extension direction of the third side portion 106 is parallel to the axial direction of the liquid storage device 26. The liquid storage device 26 is installed on the third side portion 106. The liquid storage device 26 is fixedly connected or limit-connected to the third side portion 106. Along the extension direction of the flow channel plate assembly 1, part of the liquid storage device 26 overlaps with the flow channel plate assembly 1. In other embodiments, the liquid storage device 26 can also be installed on the fourth side portion 107.

[0044] At least a portion of the liquid storage device 26 is located on the same side of the flow channel plate assembly 1 as the condenser 21. The axial direction of the liquid storage device 26 is substantially parallel to the stacking direction of the plates of the condenser 21. This effectively utilizes the space around the condenser 21 to arrange the larger liquid storage device 26, which is beneficial for improving space utilization. It should be noted that the two directions being substantially parallel can be the same direction or there can be a deviation within the range of 0-10 degrees.

[0045] Heat exchanger 23 and evaporator 22 are located on the same side of the flow channel plate assembly, which is equivalent to placing the heat exchanger connected to the medium-temperature flow channel and the low-temperature flow channel on the same side, while condenser 21 connected to the high-temperature flow channel is located on the opposite side, which helps reduce harmful heat transfer. Specifically, the projections of heat exchanger 23 and liquid storage device 26 on first surface S partially overlap, allowing for a compact arrangement of first flow channel 11 between heat exchanger 23 and liquid storage device 26. As can be seen from the above, one channel of heat exchanger 23 is directly connected to liquid storage device 26 via flow channel 10.

[0046] The heat exchanger 23, the evaporator 22, and the valve component 24 are all fixedly connected to the second side portion 105 of the flow channel plate assembly 1. Along the first direction X, at least two valve components 24 are located between the heat exchanger 23 and the evaporator 22, which also facilitates the compact arrangement of the flow channel 10. The flow channels 10 communicating with the heat exchanger 23 and the evaporator 22 are respectively arranged on both sides of at least some of the valve components 24.

[0047] At least a portion of the compression unit 3 and the condenser 21 are located on the same side of the flow channel plate assembly 1. The axis of the compression unit 3 is roughly parallel to the extension direction of the plates of the condenser 21. The condenser 21 is located at the end of the compression unit 3, and the liquid storage device 26 is located on the other adjacent side of the compression unit 3. Specifically, the condenser 21 is located near the end where the outlet 31 is provided, and the liquid storage device 26 is located near the other end where the first inlet 32 is provided. This arrangement can shorten the length of the first tube 41 and reduce the heat dissipation of the high-temperature refrigerant in the first tube 41. The arrangement of the condenser 21 and the liquid storage device 26 on different adjacent sides of the compression unit 3 can improve space utilization and facilitate the compact arrangement of the fluid control assembly.

[0048] The compression unit 3 includes a control part 30. Along the extension direction of the flow channel plate assembly 1, at least part of the control part 30 overlaps with the flow channel plate assembly 1, so that the distance between the control part 30 and the valve component 24 is shortened, which facilitates the centralized arrangement of the electrical part of the fluid control assembly.

[0049] Example 2:

[0050] Different from the first embodiment, in this embodiment, the evaporator 22 is a plate heat exchanger, and the corresponding valve component 24 and sensor 25 are one less than those in the first embodiment, and the second valve 242 is not included.

[0051] The evaporator second matching part 2202 corresponding to the evaporator second connection part 1522 is arranged along the short side of the plate of the evaporator 22, that is, when the short side of the evaporator 22 is arranged along the second direction Y, it is convenient for the evaporator second matching part 2202 to be arranged along the side of the flow channel plate assembly 1.

[0052] The heat exchanger 23, the evaporator 22, and the valve component 24 are all fixedly connected to the second side portion 105 of the flow channel plate assembly 1. The valve components 24 are arranged in rows and centrally. Along the second direction Y, the valve components 24 are located on one side of the evaporator 22. Along the first direction X, the valve components 24 are located on one side of the heat exchanger 23. The axial direction of the valve component 24 is consistent with the stacking direction of the plates of the evaporator 22, thereby improving the space utilization of the fluid control assembly.

[0053] In this embodiment, the inlet 1311 and the first outlet 1312 are both located on the second side 105 of the first plate 101 and open toward the negative direction of the third direction Z, or away from the direction of gravity, to facilitate installation of the tube assembly 4 from the top of the flow channel plate assembly 1 .

[0054] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. For example, with respect to the directional definitions of “front”, “back”, “left”, “right”, “up”, and “down”, although this specification has described the present application in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that a person of ordinary skill in the art can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included within the scope of the claims of the present application.
