[0040] In order to make the purpose, technical solution and advantages of the present application more clear, 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 such actual relationship or order between these components.

[0041] The fluid control component can be applied to a thermal management system, wherein the thermal management system can be a vehicle thermal management system, such as a new energy vehicle thermal management system.

[0042] One embodiment of the present application provides an integrated component 1000, such as Figure 1As shown, the integrated assembly 1000 includes a flow channel plate assembly 10.

[0043] like Figure 1-Figure 5 As shown, the flow channel plate assembly 10 includes an interface portion 1100, and the interface of the interface portion 1100 is connected to the flow channel 1200. In other words, the flow channel 1200 includes an interface flow channel formed by the inner cavity of the interface portion 1100. The flow channel 1200 also includes the flow channels between the plates of the flow channel plate assembly 10 and the built-in flow channels or through flow channels formed inside the plates of the flow channel plate assembly 10. Figure 3 As shown, a first direction X, a second direction Y, and a third direction Z are defined, a first surface is defined as a vertical surface, and the first surface is perpendicular to the second direction Y, and a second surface is defined as a horizontal surface, and the second surface is perpendicular to the third direction Z. The flow channel plate assembly 10 is parallel to the first surface, and the specific flow channel plate assembly 10 includes a first flow channel plate 1300 and a second flow channel plate 1400, and at least part of the first flow channel plate 1300 and at least part of the second flow channel plate 1400 are arranged relatively along the second direction Y.

The linear arrangement described here is one of the arrangement methods of the valve components, and the valve components can also be arranged nonlinearly or in other ways.

[0046] The valve component 1500 is controlled by the control unit, and part of the valve component 1500 is located in the control unit, which is fixedly connected to the first flow channel plate 1300 and the second flow channel plate 1400 respectively.

Specifically, the valve component 1500 can directly connect or throttle the flow channel 1200 when controlling the flow channel 1200 to be connected. In this embodiment, the fifth valve component 1505 and the sixth valve component 1506 are expansion valves, and throttling communication can be achieved between the part of the flow channel 1200 connected to the corresponding installation cavity.

[0047] like Fig.18 As shown, the first flow channel plate 1300 includes a third plate 1310 and a fourth plate 1320, the third plate 1310 and / or the fourth plate 1320 have a groove forming a portion of the flow channel 1200, and the third plate 1310 and the fourth plate 1320 are fixedly connected or limitedly connected. In this embodiment, the third plate 1310 has a groove forming the flow channel 1200, the fourth plate 1320 is at least partially a flat plate, the flat plate and the groove are assembled to form a portion of the flow channel 1200, and the third plate 1310 and the fourth plate 1320 are welded. Similarly, the second flow channel plate 1400 includes a fifth plate 1410 and a sixth plate 1420, the fifth plate 1410 and / or the sixth plate 1420 have a groove forming another portion of the flow channel 1200, and the fifth plate 1410 and the sixth plate 1420 are fixedly connected or limitedly connected. In this embodiment, the fifth plate 1410 has a groove forming the flow channel 1200, and the sixth plate 1420 is at least partially a flat plate. The flat plate and the groove are assembled to form another part of the flow channel 1200. The fifth plate 1410 and the sixth plate 1420 are welded together.

[0048] like Figure 4 and Figure 5As shown, the side walls of the first flow channel plate 1300 and the second flow channel plate 1400 both include an interface portion 1100, and part of the interface portion 1100 connects the first flow channel plate 1300 and the second flow channel plate 1400, and the connection can be a limited connection or a fixed connection. The seventeenth interface portion 1117 and the nineteenth interface portion 1119 are located on the side wall of the fourth plate 1320, and the interface of the seventeenth interface portion 1117 and the interface of the nineteenth interface portion 1119 are in communication with part of the flow channel 1200 in the first flow channel plate 1300. The eighteenth interface portion 1118 and the twentieth interface portion 1120 are located on the side wall of the fifth plate 1410, and the interface of the eighteenth interface portion 1118 and the interface of the twentieth interface portion 1120 are in communication with another part of the flow channel 1200 in the second flow channel plate 1400. The seventeenth interface portion 1117 is butt-connected with the eighteenth interface portion 1118, the nineteenth interface portion 1119 is butt-connected with the twentieth interface portion 1120, the interface of the seventeenth interface portion 1117 is communicated with the interface of the eighteenth interface portion 1118, and the interface of the nineteenth interface portion 1119 is communicated with the interface of the twentieth interface portion 1120. Of course, in other embodiments, they can also be connected as a whole only through a pair of interfaces, and the flow channels 1200 in the first flow channel plate 1300 and the second flow channel plate 1400 can be communicated only through a pair of interfaces. In this embodiment, the seventeenth interface 1117 and the eighteenth interface 1118 are butt-welded, and the nineteenth interface 1119 and the twentieth interface 1120 are fixedly connected by bolts.

[0049] The integrated component 1000 further includes a heat exchange unit 1800, which has a high temperature channel 1821 and a low temperature channel 1822. The high temperature medium flowing in the high temperature channel 1821 and the low temperature medium flowing in the low temperature channel 1822 can exchange heat. Figure 8 As shown, the heat exchange part 1800 is parallel to the first surface, and the heat exchange part 1800 includes a first plate 1830 and a second plate 1840. The first plate 1830 and / or the second plate 1840 have a groove forming a high-temperature channel 1821, and the first plate 1830 and / or the second plate 1840 have a groove forming a low-temperature channel 1822. The first plate 1830 and the second plate 1840 are fixedly connected or limitedly connected. In this embodiment, the first plate 1830 has a groove forming a channel of the heat exchange part 1800, and the second plate 1840 is at least partially a flat plate structure. The groove and the flat plate are combined to form the channel of the heat exchange part 1800. The first plate 1830 and the second plate 1840 are welded and connected. The groove forming the high-temperature channel 1821 on the first plate 1830 is combined with the second plate to form the high-temperature channel 1821. Similarly, the groove forming the low-temperature channel 1822 on the first plate 1830 is combined with the second plate to form the low-temperature channel 1822. This type of heat exchange part 1800 has a simple structure and can make full use of the remaining space of the integrated component 1000 to adjust the shape and size of the heat exchange part 1800, thereby improving the heat exchange efficiency of the heat exchange part 1800 and further improving the overall performance of the integrated component 1000.

[0050] like Fig.11 As shown, the heat exchange part 1800 includes a heat exchange wall 1850, which extends perpendicularly to the third side wall 1832 of the first plate 1830, and the heat exchange wall 1850 separates the high temperature channel 1821 and the low temperature channel 1822. The heat exchange wall 1850 can transfer heat, and the high temperature channel 1821 and the low temperature channel 1822 are distributed on both sides of the heat exchange wall 1850. The heat exchange part 1800 is parallel to the first surface, and at least part of the heat exchange wall 1850 is projected in an S shape on the first surface. The S-shaped structure can meet the requirement that the extension length of the heat exchange wall 1850 is longer in a smaller space, and then the length of the heat exchange channels on both sides is longer, and then the refrigerant in the high temperature channel 1821 and the low temperature channel 1822 has a larger contact area with the heat exchange wall 1850, and can further fully exchange heat. In addition, at least part of the heat exchange wall 1850 is wavy, and the wavy heat exchange wall 1850 can further increase the contact area between the fluid and it, thereby improving the heat exchange efficiency. In this embodiment, the heat exchange wall 1850 in the first direction X is wavy, and the heat exchange wall 1850 in the S-shaped bending area is a smooth curved wall. This arrangement, on the one hand, increases the contact area between the local heat exchange wall 1850 and the fluid and thus increases the heat exchange efficiency. On the other hand, ensuring the smooth surface of the heat exchange wall 1850 in the S-shaped bending area can reduce the fluid flow resistance and also increase the heat exchange efficiency.

[0051] The heat exchange portion 1800 includes a guide wall 1860, which extends perpendicularly to the third side wall 1832 from the third side wall 1832 of the first plate 1830. It can also be said that the third side wall 1832 is perpendicularly recessed to form a part of the high-temperature channel 1821 or a part of the low-temperature channel 1822. The third side wall 1832 that is not recessed serves as the guide wall 1860, and the medium in the channel can flow along the guide wall 1860. In this embodiment, the guide wall 1860 includes an end, and the medium can flow back around the end to increase the flow of the channel, thereby increasing the heat exchange efficiency. This structural design is coordinated with the structural design of the heat exchange wall 1850. In this embodiment, the projection of the heat exchange wall 1850 on the first surface is S-shaped, and the guide wall 1860 includes a high-temperature guide wall and a low-temperature guide wall. The guide wall 1860 can be designed to be smooth or wavy according to the flow resistance requirements and heat exchange efficiency requirements of the heat exchange part 1800. In this embodiment, the high-temperature guide wall is wavy and the low-temperature guide wall is smooth.

[0052] An interface portion 1100 is provided on the side wall of the flow channel plate assembly 10. Part of the interface portion 1100 is formed by protruding from the side wall of the flow channel plate assembly 10 in a direction away from the side wall of the flow channel plate assembly 10, or the interface portion 1100 is a separate component fixedly connected to the flow channel plate assembly 10, such as being welded as a whole, or the interface portion 1100 is an opening area of ​​the flow channel 1200 on the side wall of the flow channel plate. The interface portion 1100 includes an external interface portion and an internal interface portion. It should be noted here that the internal and external are relative to the integrated component 1000. The external interface is connected to other thermal management components outside the integrated component 1000, and the internal interface is connected to various components in the integrated component 1000. Fig.19 It is a schematic diagram of the refrigerant working principle and connection relationship of the integrated component 1000, wherein other thermal management components outside the integrated component 1000 include a compressor, a first heat exchanger, a first heat exchanger and an expansion unit.

[0053] The internal interface portion includes a first interface portion 1101, a second interface portion 1102, a third interface portion 1103, and a fourth interface portion 1104. Figure 7 and Fig.12 As shown, the third plate 1310 of the first flow channel plate 1300 includes a first side wall 1311, and the first interface portion 1101, the second interface portion 1102, the third interface portion 1103, and the fourth interface portion 1104 are located on the first side wall 1311. It can also be said that the first interface portion 1101, the second interface portion 1102, the third interface portion 1103, and the fourth interface portion 1104 are the opening area of ​​the flow channel 1200 on the first side wall 1311, and at least part of the first side wall 1311 is parallel to the first surface.

[0054] like Figure 8 As shown, the first plate 1830 of the heat exchange part 1800 includes a second side wall 1831, the heat exchange part 1800 includes a matching part 1810, the matching part 1810 is located on the second side wall 1831, the matching part 1810 includes a first matching part 1811, a second matching part 1812, a third matching part 1813, and a fourth matching part 1814, the high temperature channel 1821 has an opening in the first matching part 1811 and the second matching part 1812, and the low temperature channel 1822 has an opening in the third matching part 1813 and the fourth matching part 1814. At least a portion of the second side wall 1831 is parallel to the first surface.

[0055] like Figure 6As shown, at least part of the first side wall 1311 and at least part of the second side wall 1831 are parallel to each other and arranged oppositely along the first surface, the first interface portion 1101 is fixedly connected to the first matching portion 1811, the second interface portion 1102 is fixedly connected to the second matching portion 1812, the third interface portion 1103 is fixedly connected to the third matching portion 1813, the fourth interface portion 1104 is fixedly connected to the fourth matching portion 1814, and the flow channel plate assembly 10 is fixedly connected as a whole with the heat exchange portion 1800. The interface portion 1100 connected to the heat exchange portion 1800 is located on the same side wall, and the matching portion 1810 connected to the flow channel plate assembly 10 is also located on the same side wall. This connection method is simple and compact in structure. In other embodiments, the interface portion 1100 and the matching portion 1810 can also be connected in other ways, such as a limit connection. In this embodiment, the first interface portion 1101, the second interface portion 1102, the third interface portion 1103, and the fourth interface portion 1104 respectively include corresponding welding portions 110, and the flow channel plate assembly 10 and the heat exchange portion 1800 are welded and connected through multiple welding portions 110. Specifically, the welding portion 110 includes a groove for accommodating welding materials and welding materials, and at least part of the welding material is located in the groove. Of course, the welding material can also be fixed to the first side wall 1311 in other fixed ways, or the matching portion 1810 of the heat exchange portion 1800 can also include a welding portion 110, and the welding portion 110 is welded and connected with the corresponding interface portion 1100. The welding portion 110 is suitable for hot furnace welding of the heat exchange portion 1800 and the flow channel plate assembly 10. After the various components that need to be welded in the integrated assembly 1000 are assembled, the overall hot furnace welding is completed, and the process is simple. Of course, in other embodiments, the heat exchange portion 1800 can also be connected to the flow channel plate assembly 10 by other fixed connection methods or welding connection methods.

[0056] As a separate component, the heat exchange portion 1800 can be manufactured separately from the flow channel plate assembly 10 , thereby reducing the difficulty of manufacturing the flow channel plate assembly 10 .

[0057] like Figure 3 , Figure 6 and Figure 7 As shown, part of the first side wall 1311 is recessed in a direction perpendicular to the first surface, at least part of the second side wall 1831 is located in the recessed area of ​​the first side wall 1311, and part of the recessed area of ​​the first side wall 1311 is matched with the peripheral wall of the heat exchange part 1800. When the heat exchange part 1800 is assembled with the flow channel plate assembly 10, the heat exchange part 1800 is placed in the recessed area of ​​the first side wall 1311, which can limit the movement of the heat exchange part 1800 along the first surface to ensure that the interface part 1100 and the matching part 1810 are not greatly offset when they are welded. Fig.15 , Fig.13 , Fig.17As shown, the flow channel plate assembly 10 has a high-temperature flow channel 1210 and a low-temperature flow channel 1230, and the high-temperature flow channel 1210 and the low-temperature flow channel 1230 are respectively distributed in the first flow channel plate 1300 and the second flow channel plate 1400. Specifically, the first flow channel plate 1300 has a first high-temperature flow channel 1211 and a first low-temperature flow channel 1231, and the second flow channel plate 1400 has a second high-temperature flow channel 1212 and a second low-temperature flow channel 1232. Generally, according to the control of the valve component 1500, the integrated assembly 1000 is applicable to multiple working modes. Part of the flow channel 1200 is a high-temperature flow channel 1210 in one working mode and may be a low-temperature flow channel 1230 in another working mode. Therefore, the high-temperature flow channel 1210 and the low-temperature flow channel 1230 in the present application do not limit the flow channels to only flow high-temperature refrigerant or low-temperature refrigerant, but only illustrate that in a certain working mode, the high-temperature flow channel 1210 flows high-temperature refrigerant and the low-temperature flow channel 1230 flows low-temperature refrigerant.

Specifically, the coolant flow channel 1220 runs through the first flow channel plate 1300, one end of the coolant flow channel 1220 is connected to the coolant channel of the heat exchanger 1700, and the other end of the coolant flow channel 1220 is connected to the flow channel of the coolant integrated component in the thermal management system. The refrigerant channel of the heat exchanger 1700 is connected to a part of the flow channel 1200 in the first flow channel plate 1300. Specifically, the refrigerant channel of the heat exchanger 1700 is connected to the low-temperature flow channel 1230 in the first flow channel plate 1300.
