The structure and principle of positioning the pressure plate and the first header 1 are similar to the structure and principle of positioning the fixed bracket and the first header 1. The present application takes the first piece 5 as an example of a fixed bracket to illustrate the positioning structure and principle of the first piece 5 and the first header 1.

[0043] In the embodiments of the present application, Figure 3 and Figure 4 As shown, the first header 1 includes a first tube wall 11 located around the inner cavity of the first header 1, and the first tube wall 11 includes a first inner surface 13 and a first outer surface 14. The first inner surface 13 is closer to the inner cavity of the first header 1 than the first outer surface 14. Fig.10 As shown, in a cross section perpendicular to the length direction L1 of the first header 1, the first outer surface 14 is circular, and the first inner surface 13 is circular.

[0044] like Figure 3 and Figure 4 As shown, the first header 1 includes two first ridges 3, and the first ridges 3 are located on the first outer surface 14. Figure 5 , Figure 6 and Figure 7 As shown, the first member 5 is fixedly connected to the first manifold 1, the first member 5 includes a first surface 55, the first surface 55 is attached to the first outer surface 14, the first member 5 has two first grooves 52, the two first grooves 52 are matched with the two first ridges 3 in a one-to-one manner, and the corresponding first ridges 3 are at least partially located in the corresponding first grooves 52, the first member 5 includes a second surface 53 and a third surface 54, the second surface 53 and the third surface 54 are respectively located on opposite sides of the length direction L52 of the first groove 52, and the first groove 52 runs through the second surface 53 and the third surface 54. Figure 6 , Figure 7 and Fig. 9As shown, the first convex rib 3 includes a first convex structure 31 and a second convex structure 32, the first convex structure 31 and the second convex structure 32 are respectively located on opposite sides of the length direction L52 of the first groove 52, the first convex structure 31 includes a first end surface 311, the second convex structure 32 includes a second end surface 321, the first end surface 311 is attached to the second surface 53, and the second end surface 321 is attached to the third surface 54. When the first convex rib 3 and the first groove 52 are matched one by one, the first member 5 is constrained and fixed relative to the first manifold 1 except for the axial degree of freedom and the radial degree of freedom. The first protrusion structure 31 and the second protrusion structure 32 are located on opposite sides of the length direction L52 of the first groove 52, that is, the first protrusion structure 31 and the second protrusion structure 32 are located on opposite sides of the first piece 5 along the length direction L1 of the first header 1, so as to realize the axial freedom constraint of the first piece 5 relative to the first header 1; the first end face 311 of the first protrusion structure 31 is attached to the second face 53 of the first piece 5, and the second end face 321 of the second protrusion structure 32 is attached to the third face 54 of the first piece 5. Through the friction between the first end face 311 and the second face 53, and the friction between the second end face 321 and the third face 54, the radial freedom constraint of the first piece 5 relative to the first header 1 is realized. At this point, the first piece 5 is completely positioned relative to the first header 1, thereby realizing the firm positioning of the heat exchange assembly 100 before brazing. In other optional embodiments of the present application, the number of the first ridges 3 can be one or more, and the number of the first grooves 52 can be one or more. In the embodiment of the present application, the example is taken that the number of first ridges 3 is two and the number of first grooves 52 is two; when the number of first ridges 3 is two and the number of first grooves 52 is two, it is a more appropriate choice based on the dual considerations of the material usage and firm positioning of the heat exchange component 100, but the present application is not limited to this.

[0045] like Figure 8 and 10 As shown, the first ridge 3 includes a first side surface 33 and a second side surface 34, and the first side surface 33 and the second side surface 34 are respectively located on opposite sides of the width direction W3 of the first ridge 3. In the cross section perpendicular to the length direction L1 of the first manifold 1, the length of the first side surface 33 is a, the length of the second side surface 34 is b, and the thickness of the first tube wall 11 is c, wherein when b≥a, a≥1.5c, or when a≥b, b≥1.5c. When b≥a, a≥1.5c, or when a≥b, b≥1.5c, this arrangement can ensure the matching stability of the corresponding first ridge 3 and the first groove 52, thereby making the positioning of the heat exchange component 100 before brazing more secure. In the embodiment of the present application, as Fig.10As shown, the first member 5 includes a groove wall 58 located around the first groove 52, the first side surface 33 is fitted and connected to the groove wall 58 around the first groove 52, and the second side surface 34 is fitted and connected to the groove wall 58 around the first groove 52. This arrangement further enhances the matching stability of the corresponding first convex ridge 3 and the first groove 52; of course, in other optional embodiments, there is a gap between the first side surface 33 and the groove wall 58 around the first groove 52, and / or there is a gap between the second side surface 34 and the groove wall 58 around the first groove 52. The positional relationship between the first side surface 33 and the groove wall 58 around the first groove 52 in the present application is not limited to this. In other optional embodiments, due to production and manufacturing or other reasons, the connection between the first side surface 33 and the first outer surface 14 has a smaller rounded corner, and the connection between the second side surface 34 and the first outer surface 14 has a smaller rounded corner. It should be noted that when describing the first side surface 33 and the second side surface 34, the first side surface 33 and the second side surface 34 may include a smaller rounded corner, and the present application is not limited to this.

[0046] like Figure 4 As shown, in the embodiment of the present application, the height direction H33 of the first side surface 33 of each first ridge 3 of the first manifold 1 and the height direction H34 of the second side surface 34 can be parallel to each other, the height directions H33 of the first side surfaces 33 of each first ridge 3 can be parallel to each other, and the height directions H34 of the second side surfaces 34 of each first ridge 3 can be parallel to each other. Further, as Figure 8 As shown, in the embodiment of the present application, the length direction L33 of the first side surface 33 of each first rib 3 of the first manifold 1 and the length direction L34 of the second side surface 34 can be parallel to each other, the length directions L33 of the first side surfaces 33 of each first rib 3 can be parallel to each other, and the length directions L34 of the second side surfaces 34 of each first rib 3 can be parallel to each other. This arrangement enables the first piece 5 to be assembled with the first rib 3 along the height direction H33 of the first side surface 33 and the height direction H34 of the second side surface 34 during installation, and the first piece 5 can also be assembled with the first rib 3 along the length direction L33 of the first side surface 33 and the length direction L34 of the second side surface 34. The operator can assemble the first manifold 1 and the first piece 5 according to actual conditions, so that the first piece 5 and the first manifold 1 are easily assembled.

[0047] In other optional embodiments, the height direction H33 of the first side surface 33 of each first ridge 3 of the first manifold 1 is parallel to the height direction H34 of the second side surface 34, the height directions H33 of the first side surfaces 33 of each first ridge 3 are parallel to each other, and the height directions H34 of the second side surfaces 34 of each first ridge 3 are parallel to each other. This arrangement allows the first piece 5 to be assembled with the first ridge 3 along the height direction H33 of the first side surface 33 and the height direction H34 of the second side surface 34, so that the first piece 5 is easy to assemble with the first manifold 1. In other optional embodiments, the length direction L33 of the first side surface 33 of each first ridge 3 of the first manifold 1 is parallel to the length direction L34 of the second side surface 34, the length directions L33 of the first side surfaces 33 of each first ridge 3 are parallel to each other, and the length directions L34 of the second side surfaces 34 of each first ridge 3 are parallel to each other.

In other optional embodiments, when the length direction L33 of the first side surface 33 of each first rib 3 of the first manifold 1 is parallel to the length direction L34 of the second side surface 34, the length directions L33 of the first side surfaces 33 of each first rib 3 are parallel to each other, and the length directions L34 of the second side surfaces 34 of each first rib 3 are parallel to each other, in the height direction of the first rib 3, the width of the end of the first rib 3 away from the first tube wall 11 is greater than the width of the end of the first rib 3 connected to the first tube wall 11, for example, the first rib 3 is dovetail-shaped. This arrangement allows the first piece 5 to be assembled with the first rib 3 along the length direction L33 of the first side surface 33 and the length direction L34 of the second side surface 34, and at the same time, this arrangement is conducive to the constraint of the radial freedom of the first piece 5 relative to the first manifold 1, so that the heat exchange assembly 100 is easy to assemble and firmly positioned.
