[0028] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] In related technologies, the thermal management device includes a flow channel 1 and a valve 2. The flow channel 1 is made of aluminum alloy and the valve 2 is made of copper. Welding the aluminum alloy flow channel 1 and the copper valve 2 can easily lead to electrochemical corrosion of the flow channel 1 and the valve 2, resulting in problems such as reduced sealing performance.

[0030] Therefore, this application provides a thermal management device, referring to Figure 1 , Figure 2 as well as Figure 3 The thermal management device includes a flow channel 1 and a valve 2. The valve 2 includes a valve body 21 and a valve stem 22. The valve body 21 is connected to the flow channel 1, and the valve stem 22 is located inside the valve body 21. The valve body 21 has a valve passage 211, and the flow channel 1 has a flow channel 11. The flow channel 11 can communicate with the valve passage 211, and the valve stem 22 can block the flow channel 11 from the valve passage 211. The flow channel 1 and the valve body 21 are made of the same material. The thermal management device includes a thermal management component 3, which is connected to the flow channel 1. The thermal management component 3 is at least partially located in the flow channel 11, or the channel inside the thermal management component 3 communicates with the flow channel 11.

[0031] By using the same material for the valve body 21 and the flow channel 1, electrochemical corrosion between the valve body 21 and the flow channel 1 is reduced. Specifically, both the flow channel 1 and the valve body 21 are made of aluminum alloy.

[0032] In some embodiments, the flow channel 1 is welded to the valve body 21; in some embodiments, refer to Figure 1 as well as Figure 2 The flow channel 1 and the valve body 21 are integrated into one piece.

[0033] Specifically, the flow channel 1 and the valve body 21 can be made into one piece by casting processes such as sand core, salt core, and gypsum core. Alternatively, the flow channel 1 and the valve body 21 can be made into one piece by machining an aluminum alloy block, machining the valve channel 211 and the flow channel 11 inside the aluminum alloy block.

[0034] In some implementations, refer to Figure 3 as well as Figure 4 The valve passage 211 includes a first sub-passage 2111 and a second sub-passage 2112. The valve body 21 has the first sub-passage 2111 and the second sub-passage 2112. The first sub-passage 2111 can communicate with the second sub-passage 2112. The valve body 21 has a receiving hole 212, which communicates with the second sub-passage 2112. The valve stem 22 is at least partially located in the receiving hole 212.

[0035] Specifically, refer to Figure 3 as well as Figure 4 The valve stem 22 has a first annular groove 222. The thermal management device includes a seal 223, part of which is located within the first annular groove 222. The seal 223 contacts the wall corresponding to the receiving hole 212, thereby achieving a seal between the valve stem 22 and the wall corresponding to the receiving hole 212. Furthermore, the valve body 21 has a second annular groove 224, which is recessed from the wall corresponding to the receiving hole 212. The second annular groove 224 is located on the side of the valve stem 22 away from the first sub-channel 2111. The thermal management device includes a retaining ring 225, part of which is located in the second annular groove 224, and the other part of which is located in the receiving hole 212. The retaining ring 225 can prevent the valve stem 22 from rotating out of the threaded portion 2121.

[0036] Specifically, refer to Figure 3 as well as Figure 4 The thermal management device includes a threaded portion 2121, which is connected to the wall corresponding to the receiving hole 212. The threaded portion 2121 is located on the periphery of the valve stem 22 and is threadedly connected to the valve stem 22. Furthermore, the threaded portion 2121 and the wall corresponding to the receiving hole 212 are integral parts.

[0037] In some implementations, refer to Figure 3 as well as Figure 5The valve stem 22 has a rotating groove 221. The rotating groove 221 has a non-circular cross-section and can be a regular hexagon, a regular pentagon, or other shapes. When it is necessary to adjust the flow rate in the valve passage 211, a tool that matches the rotating groove 221 can be inserted into the rotating groove 221 to drive the valve stem 22 to rotate, thereby controlling the flow rate in the valve passage 211.

[0038] In some implementations, refer to Figure 3 , Figure 4 as well as Figure 5 The valve passage 211 includes a first sub-passage 2111 and a second sub-passage 2112. The valve body 21 has the first sub-passage 2111 and the second sub-passage 2112. The first sub-passage 2111 can communicate with the second sub-passage 2112. The valve body 21 has a receiving hole 212 that penetrates the wall corresponding to the first sub-passage 2111 or the second sub-passage 2112. The valve stem 22 is at least partially located in the receiving hole 212.

[0039] In some implementations, refer to Figure 3 , Figure 4 as well as Figure 5 The extension direction of the first sub-channel 2111 intersects the extension direction of the second sub-channel 2112. Specifically, the extension direction of the first sub-channel 2111 is defined as the first direction X1, and the extension direction of the second sub-channel 2112 is defined as the second direction X2. The first direction X1 and the second direction X2 are perpendicular.

[0040] In some implementations, refer to Figure 3 , Figure 4 as well as Figure 5 The extending direction of the receiving hole 212 is parallel to the extending direction of the first sub-channel 2111. Specifically, the receiving hole 212 and the first sub-channel 2111 are coaxially arranged, and the extending direction of the receiving hole 212 is parallel to the first direction X1.

[0041] In some implementations, refer to Figure 6 The valve passage 211 includes a third sub-passage 2113, which communicates with the first sub-passage 2111. The thermal management device includes a valve core 23, which is at least partially located in the third sub-passage 2113. Specifically, the valve core 23 and the third sub-passage 2113 are used to replenish the refrigerant in the flow channel 11 of the flow channel section 1. The valve core 23 is normally closed under normal conditions.

[0042] Specifically, the valve core 23 is threaded to the wall of the third sub-channel 2113, and the valve core 23 is sealed to the wall of the third sub-channel 2113.

[0043] In some implementations, refer to Figure 6The extension direction of the third sub-channel 2113 is parallel to the extension direction of the second sub-channel 2112. Specifically, the extension direction of the third sub-channel 2113 is parallel to the second direction X2, and the third sub-channel 2113 and the second sub-channel 2112 are coaxially arranged.

[0044] In some implementations, refer to Figure 6 Along the second direction X2, the first sub-channel 2111 and the receiving hole 212 are both located between the second sub-channel 2112 and the third sub-channel 2113.

[0045] The valve body 21 is made of aluminum alloy and needs to be connected to a stainless steel or copper refrigerant pipe. The welding of the stainless steel or copper refrigerant pipe to the aluminum alloy valve body 21 is mostly done by brazing. Solder is placed between the refrigerant pipe and the valve body 21 and then reflow soldering is performed. Part of the solder contacts the stainless steel refrigerant pipe and the other part contacts the aluminum alloy valve body 21, so that there are two contact surfaces between the solder and the valve body 21 and the refrigerant pipe. The sealing performance needs to be improved and the cost is relatively high. In the air conditioning field, the pressure of the refrigerant is relatively high, and the requirements for sealing performance are also high.

[0046] In some implementations, refer to Figure 4 as well as Figure 5 The thermal management device includes an intermediate part 12, which has a channel 121 that penetrates the intermediate part 12 and communicates with the valve channel 211. The thermal management device also includes a solder part 24, which is integral with the valve body 21. The melting point of the intermediate part 12 is greater than that of the solder part 24. The solder part 24 has a contact wall 241 that directly contacts and seals the intermediate part 12.

[0047] By making the solder part 24 and the valve body 21 an integral part, the contact surface between the solder part 24 and the valve body 21 is reduced. Compared with brazing, the welding surface is reduced and the welding surface is made into one piece, which improves the sealing performance.

[0048] Specifically, the intermediate part 12 has an embedded wall located between the intermediate part 12 and the contact wall 241. The area of ​​the embedded wall located in the mounting hole 242 is defined as the first area, and the area of ​​the embedded wall in contact with the contact wall 241 is defined as the second area. The ratio of the second area to the first area is greater than or equal to 0.9.

[0049] Furthermore, both the solder section 24 and the valve body 21 are made of aluminum alloy, while the intermediate section 12 is made of stainless steel. The melting point of stainless steel is higher than that of aluminum alloy. Traditional thermal management devices use copper or stainless steel tubing externally. Welding copper tubing to the aluminum alloy valve body 21 may lead to electrochemical corrosion between copper and aluminum. Welding stainless steel tubing to the aluminum alloy valve body 21 is difficult, typically requiring brazing, which is costly and compromises sealing performance. This solution directly connects the stainless steel intermediate section 12 to the aluminum alloy solder section 24, making the solder section 24 and valve body 21 a single unit. The external stainless steel or copper tubing is welded to the aluminum alloy valve body 21 via the stainless steel intermediate section 12, making welding more convenient and improving adaptability.

[0050] In some implementations, refer to Figure 4 as well as Figure 5 The solder section 24 has a mounting hole 242, the contact wall 241 is located in the mounting hole 242, and the intermediate section 12 is at least partially located in the mounting hole 242. Placing the intermediate section 12 into the mounting hole 242 can increase the contact area between the solder section 24 and the intermediate section 12, further improve the sealing performance, and also improve the structural strength of the intermediate section 12 mounted on the solder section 24.

[0051] In some implementations, refer to Figure 4 as well as Figure 5 The valve body 21 has a limiting surface 213, which is located between the second sub-channel 2112 and the intermediate portion 12, and the limiting surface 213 is in direct contact with the intermediate portion 12. Specifically, the limiting surface 213 faces the intermediate portion 12, and the limiting portion can limit the intermediate portion 12. The limiting surface 213 is in direct contact with the intermediate portion 12, which improves the accuracy of the intermediate portion 12 in the position of the mounting hole 242.

[0052] In some implementations, refer to Figure 2 as well as Figure 6 The valve passage 211 includes a first sub-passage 2111, a second sub-passage 2112, and a third sub-passage 2113.

The first sub-passage 2111 is connected to the second sub-passage 2112, and the third sub-passage 2113 is connected to the first sub-passage 2111. The thermal management device includes a valve core 23, which is at least partially located in the third sub-passage 2113. The thermal management device includes a first cover 251, a second cover 252, and a third cover 253.

[0058] In some implementations, refer to Figure 8 as well as Figure 9The second flow channel 112 includes a first sub-flow channel 11, which is connected to the first silencing cavity 1121. The flow area between the two ends of the first silencing cavity 1121 is larger than the flow area of ​​the first sub-flow channel 11.

[0060] In related technologies, a thermal management device includes a flow channel, a throttling valve, a first filter, and a second filter. The throttling valve has a first port and a second port. In heating mode, refrigerant enters through the first port and exits through the second port. The first filter filters the refrigerant entering through the first port. In cooling mode, refrigerant enters through the second port and exits through the first port. The second filter filters the refrigerant entering through the second port. The flow channel includes a flow channel, a first filter chamber, and a second filter chamber. The first filter is located in the first filter chamber, and the second filter is located in the second filter chamber. The flow channel has a receiving groove, and the throttling valve is located in the receiving groove. The receiving groove communicates with the flow channel, the first filter chamber, and the second filter chamber. The flow area of ​​both the first and second filter chambers is larger than the flow area of ​​the flow channel within the flow channel. This can easily lead to a complex flow channel within the flow channel. The flow channel includes a first filter chamber, a second filter chamber, a flow channel, and a receiving chamber, with the flow channel connecting the first filter chamber, the second filter chamber, and the receiving chamber.
