[0044] Combination Figure 3-Figure 12 , the present embodiment is described in detail using the pump 201 as the thermal management element 200. For a more detailed description, Figure 3-Figure 12 Only the connection diagram of the pump 201 and part of the mounting portion 10 is shown. Specifically, the axial direction of the mounting cavity 11 is defined as the first direction, and the second direction is defined to be perpendicular to the first direction. The mounting portion 10 has a first clamping portion 12, and the first clamping portion 12 is located on the peripheral wall of the mounting portion 10. The pump 201 includes a second clamping portion 21, and the second clamping portion 21 is located on the peripheral wall of the pump 201. The fastener 30 is elastic. Along the first direction, the first clamping portion 12 and the second clamping portion 21 are arranged relative to each other. During assembly, at least part of the fastener 30 is located on the first clamping portion 12, and at least part of the fastener 30 is located on the second clamping portion 21, thereby limiting the movement of the pump 201 along the first direction. The first clamping portion 12 includes a first limiting portion 121, a second limiting portion 122 and a first accommodating cavity 123. The first limiting portion 121 is arranged along the first direction, and the second limiting portion 122 is arranged along the circumference of the mounting portion 10. Along the second direction, the first accommodating cavity 123 runs through the inner and outer walls of the mounting portion 10.

[0045] The fastener 30 is elastic, and its shape is similar to that of the mounting portion 10. In the present embodiment, the fastener 30 is annular, and has a notch 33, that is, the fastener 30 has a first end 31 and a second end 32, and both the first end 31 and the second end 32 are free ends, and a notch 33 is formed between the first end 31 and the second end 32. The fastener 30 includes a clamping portion 34 and a coupling portion 35, the clamping portion 34 is fixedly connected to the coupling portion 35, and the clamping portion 34 and the coupling portion 35 are arranged at intervals, that is, the coupling portion 35 is located between two adjacent clamping portions 34. It can also be understood that the two ends of the coupling portion 35 are respectively fixedly connected to the ends of the two clamping portions 34. The number of coupling portions 35 is defined as N, then the number of clamping portions 34 is N+1, and N is greater than or equal to 1. When the fastener 30 is in a free state, the distance from the clamping portion 34 to the axis of the fastener 30 is defined as L1, and the distance from the coupling portion 35 to the axis of the fastener 30 is defined as L2, and L2 is greater than L1.

[0046] The first engaging portion 12 of the mounting portion 10 is arranged opposite to the engaging portion 34, and the number of the engaging portions is the same as the number of the engaging portions 34. The engaging portions are arranged along the circumference of the mounting portion 10, and the first accommodating cavities 123 of two adjacent first engaging portions 12 are not connected along the circumference of the mounting portion 10. During assembly, the fastener 30 is engaged with the mounting portion 10, and at this time, the fastener 30 is in the first state, at least part of the engaging portion 34 of the fastener 30 is located in the first accommodating cavity 123 of the first engaging portion 12, at least part of the engaging portion 34 abuts against the first limiting portion 121 to limit the axial movement of the engaging portion 34, and at least part of the engaging portion 34 abuts against the second limiting portion 122 to limit the circumferential movement of the engaging portion 34. It should be noted that, due to the processing tolerance and the assembly tolerance, at least part of the clamping portion 34 abuts against the first limiting portion 121 to limit the axial movement of the clamping portion 34. The axial movement of the clamping portion 34 here is not absolutely limited, as long as it is within the tolerance range. Along the second direction, at least part of the clamping portion 34 is located on the inner side of the mounting portion 10 relative to the engaging portion 35, that is, at least part of the clamping portion 34 is located in the mounting cavity 11, part of the clamping portion 34 is located in the first accommodating cavity 123, and the engaging portion 35 is located on the outer side of the mounting portion 10 relative to the clamping portion 34.

[0047] The pump 201 includes a second engaging portion 21, which is located on the outer wall of the pump 201 and is arranged along the circumference of the pump 201. Along the radial direction of the pump 201, the second engaging portion 21 has an opening. Along the axial direction of the pump 201, that is, the first direction, the second engaging portion 21 includes a first wall portion 211 and a second wall portion 212. The first wall portion 211 and the second wall portion 212 are arranged opposite to each other. In this embodiment, the second engaging portion 21 is a groove 210 arranged along the axial direction of the pump 201. Along the second direction, the groove 210 has an opening. Along the circumference of the pump 201, the groove 210 is continuously arranged. Of course, in some embodiments, the groove 210 is intermittently arranged along the circumference of the pump 201, and the number and position of the grooves 210 correspond to the number and position of the engaging portion 34 of the fastener 30. During installation, the fastener 30 is clamped with the mounting portion 10, the pump 201 is inserted into the mounting cavity 11, the outer wall of the pump 201 abuts against part of the clamping portion 34, and force is applied to press the pump 201 downward. The fastener 30 is deformed by the force and expands radially toward the mounting portion 10. When the second clamping portion 34 is opposite to the first clamping portion 34, the fastener 30 contracts, and the clamping portion 34 of the fastener 30 is located in the groove 210, and at least part of the clamping portion 34 abuts against the first wall portion 211, and at least part of the clamping portion 34 abuts against the second wall portion 212, thereby fixing the mounting portion 10 and the pump 201.

[0048] In some other embodiments, for the convenience of installation, the pump 201 includes a first guide portion 22, which is located at the outer periphery of the pump 201. Along the first direction, the first guide portion 22 is close to the mounting portion 10 relative to the second engaging portion 21. Along the radial direction of the pump 201, i.e., the second direction, the first guide portion 22 protrudes outward from the outer wall of the pump 201, and one end of the first guide portion 22 close to the second engaging portion 21 is defined as the third end 221, and the other end is defined as the fourth end 222. Along the radial direction of the pump 201, the fourth end 222 is close to the axis of the pump 201 relative to the third end 221, i.e., along the axial direction of the pump 201, the distance from the first guide portion 22 to the axis gradually decreases from the third end 221 to the fourth end 222. In this solution, the cross section of the first guide portion 22 along the axial direction of the pump 201 is a triangle or a trapezoid. The pump 201 includes a plurality of first guide portions 22, which are arranged at intervals along the circumference of the pump 201. Of course, in some other embodiments, the first guide portion 22 is a tapered step portion located on the outer wall of the pump 201. During installation, the guide portion provides a guide for the deformation of the fastener 30, which is beneficial to the installation of the pump 201.

[0049] In some other embodiments, the first end 31 and the second end 32 of the fastener 30 are bent toward the axial direction of the fastener 30 relative to the clamping portion 34; the mounting portion 10 includes a second guide portion 13, the second guide portion 13 is located on the outer wall of the mounting portion 10, and the second guide portion 13 protrudes outward from the outer wall of the mounting portion 10. In this embodiment, two second guide portions 13 are provided, and the two second guide portions 13 are symmetrically arranged relative to the radial direction of the mounting portion 10, one of the second guide portions 13 is limitedly arranged with the first end 31 of the fastener 30, and the other second guide portion 13 is limitedly arranged with the second end 32 of the fastener 30. Taking one of the second guide portions 13 and the first end portion 31 as an example for detailed description, the second guide portion 13 includes a guide surface 133, a first abutment portion 131, and a second abutment portion 132. The first abutment portion 131 and the second abutment portion 132 are arranged along the circumference of the mounting portion 10, and the outer wall surface of the first abutment portion 131 is close to the outer wall surface of the mounting portion 10 relative to the outer wall surface of the second abutment portion 132, and the guide surface 133 of the second guide portion 13 extends from the outer wall surface of the first abutment portion 131 to the outer wall surface of the second abutment portion 132. During installation, the fastener 30 is first connected with the mounting portion 10 in a limiting position. At this time, the fastener 30 is in the first state. The first end 31 of the fastener 30 abuts against the first abutting portion 131 of the second guide portion 13, and the second end 32 of the fastener 30 abuts against the first abutting portion 131 of another second guide portion 13, limiting the circumferential movement of the second guide portion 13; then the pump 201 is inserted, the first guide portion 22 of the pump 201 abuts against part of the clamping portion 34, and force is applied to press the pump 201 downward, and the fastener 30 is deformed by the force and expands radially toward the mounting portion 10. At this time, The first end 31 and the second end 32 of the fastener 30 slide along the second guide portion 13 and deform along the radial direction of the mounting portion 10. When the second clamping portion 21 is opposite to the first clamping portion 12, the fastener 30 contracts, and the clamping portion 34 of the fastener 30 is located in the groove 210, and at least part of the clamping portion 34 abuts against the first wall portion 211, and at least part of the clamping portion 34 abuts against the second wall portion 212. Along the circumference of the mounting portion 10, part of the clamping portion 34 abuts against the first limiting portion 121 and the second limiting portion 122, thereby fixing the mounting portion 10 and the pump 201. During disassembly, the second guide portion 13 provides guidance for the deformation of the fastener 30; specifically, when the fastener 30 is disassembled, the fastener 30 moves from the first abutment portion 131 to the second abutment portion 132 along the guide surface 133, and the guide surface 133 provides guidance for the deformation of the fastener 30, and the fastener 30 expands outward. At this time, the fastener 30 disengages from the second engaging portion 21 of the pump 201, and then the pump 201 is pulled out, so that the pump 201 is separated from the mounting portion 10.Compared with the traditional threaded connection, the solution of the present application can realize the rapid installation and disassembly of the pump 201. In addition, in this solution, before installation, the fastener 30 is first clamped on the mounting portion 10, and then the pump 201 is inserted. The pump 201 and the substrate 100 are clamped together by the deformation of the fastener 30. Compared with inserting the pump 201 into the mounting portion 10 first and then clamping the fastener 30, it is more convenient.

[0050] It should be noted that the fastener 30 of the present application is a retaining spring, the shape of which can be U-shaped, square, polygonal, etc. The retaining spring is made of metal and can be elastically deformed.

[0051] For the convenience of assembly, when disassembling, the fastener 30 is separated from the pump 201, but not directly separated from the mounting portion 10, but is fixed to the mounting portion 10 by limiting position, which solves the problem of the fastener 30 being placed at will after being disassembled. Specifically, the mounting portion 10 includes a third limiting portion 14, which is located on the outer wall of the mounting portion 10, and at least part of the first end portion 31 of the fastener 30 is located in the third limiting portion 14. In this embodiment, the third limiting portion 14 is a limiting groove 141 provided on the outer wall of the mounting portion 10, and the limiting groove 141 has an opening along the radial direction of the mounting portion 10. The limiting groove 141 is adjacent to the second abutting portion 132, so that the fastener 30 is deformed along the second guide portion 13, and is located in the limiting groove 141 after being separated from the second guide portion 13 and restored. The mounting portion 10 includes two limiting grooves 141. When installing, the fastener 30 is in the first state. When disassembling, the fastener 30 is in the second state. At this time, the first end 31 of the fastener 30 is at least partially located in the limiting groove 141, and the second part of the fastener 30 is at least partially located in the other limiting groove 141, thereby limiting and fixing the fastener 30, that is, the fastener 30 is limited and fixed on the mounting portion 10. When assembling next time, the fastener 30 is directly pushed along the second direction. After the fastener 30 is subjected to force, it deforms and slides along the second guide portion 13. The fastener 30 is in the first state, that is, it is assembled again according to the above steps. With the solution of the present application, the pump 201 and the base plate 100 can be assembled and disassembled multiple times without affecting the performance of the assembly. With threaded connection, there is a risk of failure of the thread after multiple assemblies.

[0052] like Figure 1-2As shown, the thermal management component includes a substrate 100, and the substrate 100 includes an external interface 16 and a flow channel 15. The external interface 16 of the substrate 100 is mainly connected to other components in the thermal management circuit, such as a battery, a motor, a heat exchanger, etc.; the flow channel 15 of the substrate 100 is used to connect the thermal management components installed on the substrate 100, such as a pump, a valve, a heat exchanger, etc. The pump 201 includes a connection port 23, and the connection port 23 is connected to the flow channel 15. For example, the pump 201 has two connection ports 23, one of which is a connection port for fluid to enter the pump 201, and the other is a connection port for fluid to flow out of the pump 201. For example, one connection port of the pump 201 is connected to the external interface 16 of the substrate 100, that is, the above connection port is connected to other components in the thermal management circuit through the external interface 16 of the substrate 100, and the other connection port of the pump 201 is connected to the flow channel 15 of the substrate 100; or in some implementations, both connection ports of the pump 201 are connected to the flow channel 15 of the substrate 100. Of course, the above flow channels 15 are different flow channels 15. The substrate 100 and the mounting portion 10 are an integral structure, that is, the substrate 100 and the mounting portion 10 can be integrally formed. In this embodiment, the substrate 100 and the mounting portion 10 are made of plastic material, and the substrate 100 and the mounting portion 10 are injection molded; of course, the substrate 100 and the mounting portion 10 can also be metal, or one of the substrate 100 and the mounting portion 10 is made of metal, and the other is made of plastic. The substrate 100 and the mounting portion 10 are split structures, which are basically fixedly connected to the mounting portion 10 and can be fixed by welding, bonding, or threaded connection. The thermal management element 200 is fixedly connected to the mounting portion 10 or the substrate 100 through the above-mentioned fastener 30. Compared with the known technology, the thermal management element 200 can be quickly installed and removed by fixing it on the substrate 100 through traditional screws, bolts, etc., which improves the production rhythm of the production line. Compared with the fixed connection of bolts, the solution cost of this application is relatively low. On the other hand, when using traditional screws or bolts for connection, in order to improve the strength of the thread, the threaded hole is a metal part embedded in the substrate 100, and the flow channel 15 on the substrate 100 is set to avoid the threaded hole, resulting in a larger flow resistance of the fluid. The connection method of the present application can avoid the occurrence of the above problems. The thermal management element 200 of the present application includes a pump 201 and a control element of a valve 202. The valve 202 can be a one-way valve, such as Figure 1 In the embodiment, the thermal management element 200 is a multi-way valve 202 . The multi-way valve 202 has a plurality of connection ports, which are respectively connected to the flow channels 15 of the substrate 100 .

The difference from the fastener 30 in Example 1 is that the fastener 30 in this embodiment has no notch. Specifically, in the present embodiment, the fastener 30 is annular, and the first and tail ends of the fastener 30 are connected, the fastener 30 includes a clamping portion 34 and a joining portion 35, the clamping portion 34 is fixedly connected to the joining portion 35, the clamping portion 34 and the joining portion 35 are arranged at intervals, that is, the joining portion 35 is located between two adjacent clamping portions 34, it can also be understood that the two ends of the joining portion 35 are respectively fixedly connected to the ends of the two clamping portions 34, the number of joining portions 35 is defined as N, then the number of clamping portions 34 is N, and N is greater than or equal to 2; along the axial direction of the fastener 30, the joining portion 35 is bent upward or downward relative to the clamping portion 34, when the fastener 30 is in the first state, that is, the fastener 30 is clamped and fixed to the mounting portion 10, at least part of the clamping portion 34 is located in the accommodating cavity of the first clamping portion 12, and along the axial direction of the mounting portion 10, the joining portion 35 is located on one side of the first clamping portion 12.

[0055] The first clamping portion 12 of the mounting portion 10 is arranged opposite to the clamping portion 34, and the number of the first clamping portions 12 is the same as the number of the clamping portions 34. The first clamping portions 12 are arranged along the circumference of the mounting portion 10. Along the circumference of the mounting portion 10, the first accommodating cavities 123 of two adjacent first clamping portions 12 are not connected. The mounting portion 10 includes a third limiting portion 14, and the third limiting portion 14 is located on the peripheral wall portion of the mounting portion 10. The number of the third limiting portion 14 is the same as the number of the first clamping portions 12. Along the circumference of the mounting portion 10, the third limiting portion 14 is located between two adjacent first clamping portions 12. Along the radial direction of the mounting portion 10, the third limiting portion 14 protrudes outward relative to the first clamping portion 12. In this embodiment, the third limiting portion 14 is a limiting groove 141. Along the radial direction of the mounting portion 10, the limiting groove 141 has an opening, and the bottom of the limiting groove 141 is away from the axis of the mounting portion 10 relative to the first clamping portion 12.
