It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0035] The utility model provides a radiator inlet and outlet pipe support structure, such as Figure 1-3 As shown, it includes a high temperature radiator 1 and a low temperature radiator 2, and the low temperature radiator 2 can be installed with the high temperature radiator 1 by screw or buckle connection. In a preferred example, the radiator inlet and outlet pipe support structure also includes other heat dissipation modules.

[0036] The low-temperature radiator 2 includes a core 9, a first bracket 201, a second bracket 202, a first inlet and outlet pipe 7 and a second inlet and outlet pipe 8; the first bracket 201 and the second bracket 202 are respectively installed on both sides of the core 9; the first bracket 201 and the second bracket 202 are respectively connected to the high-temperature radiator 1, and the first bracket 201 and the second bracket 202 are respectively used to fix the first inlet and outlet pipe 7 and the second inlet and outlet pipe 8;

[0037] The first bracket 201 includes a first support frame 3 and a first fixing frame 4; the first support frame 3 includes a bending structure 203, the first fixing frame 4 includes a first edge structure 5, and the first edge structure 5 is provided with a plurality of notches 6;

[0038] The second bracket 202 includes a second support frame 31 and a second fixing frame 41; the second support frame 3 includes a bending structure 203, the second fixing frame 41 includes a second edging structure 51, and a plurality of notches 6 are provided on the second edging structure 51; in a preferred example, the first support frame 3 and the first fixing frame 4 are integrally formed, and the second support frame 31 and the second fixing frame 41 are integrally formed.

[0039] The first edging structure 5 and the second edging structure 51 are used to fix the first inlet and outlet pipe 7 and the second inlet and outlet pipe 8 respectively. The inner diameters R of the first edging structure 5 and the second inlet and outlet pipe 8 respectively match the first inlet and outlet pipe 7 and the second inlet and outlet pipe 8, that is, the first edging structure 5 and the second edging structure 51 respectively embrace the first inlet and outlet pipe 7 and the second inlet and outlet pipe 8. In a preferred example, Figure 1-7 As shown, in order to facilitate installation and subsequent maintenance and disassembly, the encircling is not a complete encircling, but an encircling with a preset gap. In a preferred embodiment, the first edge enclosing structure 5 and the second edge enclosing structure 51 are pre-bent.

[0040] The first bracket 201 and the second bracket 202 are respectively provided with a round hole and a waist-shaped hole; in a preferred embodiment, the high-temperature radiator has threaded holes on both sides of the water chamber, and the threaded holes on both sides match the round hole and the waist-shaped hole respectively.

[0042] In a preferred embodiment, Figure 5 As shown, the opening width W of the first edge wrapping structure 5 and the second edge wrapping structure 51 before installation is greater than the width of the inlet and outlet pipes. After the first inlet and outlet pipes 7 and the second inlet and outlet pipes 8 are installed to the first edge wrapping structure 5 and the second edge wrapping structure 51 respectively, a tool (such as pliers) is used to extrude the edge wrapping structure, as shown in FIG. Figure 7 As shown, after being squeezed by the tooling, the edge structure will begin to deform at the weak point to match the diameter of the pipe wall, that is, the edge structure completes the embracing of the inlet and outlet pipes. The first edge structure 5 and the second edge structure 51 can both be aluminum edges.

[0043] In a preferred embodiment, the number of the notches 6 on the first edge binding structure 5 and the number of the notches 6 on the second edge binding structure 51 are both 4.

[0046] The utility model forms the support frame and the fixing frame in one piece by punching and bending and other processing methods, and adds a notch at the edge of the support structure, so that the edge is deformed at the weak point of the notch after being stressed, so as to achieve the purpose of perfect fit and uniform welding after brazing. In addition, the utility model avoids the defects of the existing technology that the installation is time-consuming and labor-intensive, and special tools are required to increase the cost of the enterprise.
