[0023] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. 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.

[0024] like Figure 1 and 2 As shown, a U-shaped satellite heat pipe bending device provided by the utility model includes: a cover plate 1, a rotating handle 2, a base plate 6 and a middle template 7. One end of the base plate 6 is U-shaped, and a positioning mechanism 3 is arranged in the middle of the end. The heat pipe profile is placed on the base plate 6 through the positioning mechanism 3. The base plate 6, the middle template 7 and the cover plate 1 are arranged in sequence from bottom to top, and the three are fastened together by connecting parts. The size of the middle template 7 is adapted to the heat pipe profile; two rotating handles 2 are symmetrically installed on both sides of the U-shaped end of the base plate 6 through a rotating shaft 4. The rotating handles 2 can rotate around their corresponding rotating shafts 4. The heat pipe profile is bent by the cooperation of the rotating handle 2 and the middle template 7 to form a U-shaped satellite heat pipe.

[0025] The cover plate 1 and the bottom plate 6 are of the same shape and size, the U-shaped end and both sides of the middle template 7 are smaller than the size of the bottom plate 6, and the bottom plate 6, the middle template 7 and the cover plate 1 are fitted together. The bottom plate 6, the middle template 7 and the cover plate 1 are fastened and connected by a plurality of symmetrically distributed screws 5.

[0026] Since the springback of the profile is difficult to obtain, the shape of the middle template 7 is obtained by numerical simulation and is adjusted according to the profile in actual application. The centers of the two arcs of the U-shaped end of the middle template 7 are consistent with the centers of the two arcs of the U-shaped end of the bottom plate 6, and the two rotating shafts 4 are respectively arranged at the centers of the two arcs of the U-shaped ends of the bottom plate 6, the middle template 7 and the cover plate 1. The size of the edge of the middle template 7 to the edge of the bottom plate 6 is consistent with the width of the heat pipe profile. The thickness of the middle template 7 is consistent with the thickness of the heat pipe profile to ensure flatness and prevent distortion when bending the pipe.

[0027] The heat pipe profile is placed between the positioning mechanism 3 and the middle template 7, and the distance between the positioning mechanism 3 and the middle template 7 is consistent with the width of the heat pipe profile. The positioning mechanism 3 is fixed to the bottom plate 6, which is used to ensure that the heat pipe profile is installed in place before bending.

[0028] A small roller 8 is installed on the rotating handle 2. The rotating handle 2 slides with the bottom plate 6 through the small roller 8 to reduce the friction when bending the pipe, thereby controlling the extension of the heat pipe profile and avoiding reverse bending of the bent section of the heat pipe.

[0029] The rotating handle 2 includes an initial state and a rotating state. When the rotating handle 2 is in the initial state, the inner edge of the rotating handle 2 and the side of the positioning mechanism 3 close to the heat pipe profile are located on the same straight line.

[0030] like Figure 3 As shown in (1)-(4), the dotted line part in the figure is the heat pipe profile, and the dotted line part is the bent U-shaped satellite heat pipe. The use of this application is as follows:

[0031] Step 1, place the base plate 6 on the operating platform, and connect it to the rotating handle 2 through the rotating shaft 4;

[0032] Step 2, place the middle template 7, position it by two rotating shafts 4, place the heat pipe profile, and install the positioning mechanism 3 in place;

[0033] Step 3, install the cover plate 1, fasten the bottom plate 6, the middle template 7 and the cover plate 1, and turn the rotating handle 2 until it is in close contact with the bottom plate 6;

[0034] Step 4: Remove the cover plate 1, reset the rotary handle 2 to the initial position, and then take out the bent U-shaped satellite heat pipe.

[0035] The present application has a simple structure, is easy to adjust and use, and is suitable for single-piece small-batch production. Therefore, the pipe bending device has a low manufacturing cost and is easy to process and produce, thereby effectively improving the production qualification rate and reducing production costs.
