[0035] The end surface of the heat-conducting pipe 82 is fixedly connected with the mounting plate 83, a side middle part of the mounting plate 83 is provided with a communicating socket one 84, the setting of the socket one 84 facilitates the clamping effect of the two L-shaped elastic plates 87 of the subsequent structure, and the other side of the mounting plate 83 is fixedly connected with plug blocks one 89 on the upper and lower sides, the plug blocks one 89 facilitate the insertion effect of the socket two 86, the surface of the fixing plate 85 is fixedly connected with the surface of the U-shaped heat-conducting plate 7, and the fixing plate 85 is provided with the socket two 86 on the upper and lower sides of a side, the inner parts of the socket two 86 on the upper and lower sides are respectively inserted with the outer surfaces of the plug blocks one 89, and through the cooperation of the plug blocks one 89 and the socket two 86, a preliminary limiting effect is formed during installation.

[0036] In addition, the middle part of the fixing plate 85 is fixedly connected with the two L-shaped elastic plates 87 on the left and right sides in a mirror image, and the left and right horizontal directions of the two L-shaped elastic plates 87 are provided with inclined surfaces, the setting of the inclined surfaces facilitates the extrusion of the inclined surfaces in the inside of the socket one 84 during installation, the L-shaped elastic plates 87 are deformed and bent, the two L-shaped elastic plates 87 are bent and close to each other, and when the box body 81 is pushed again, the two L-shaped elastic plates 87 are completely inserted in the inside of the socket one 84, and the clamping and limiting effect of the mounting plate 83 is realized through resetting.

[0037] The surfaces of the two L-shaped elastic plates 87 are fixedly connected with a strip-shaped handle 88, the outer surfaces of the two L-shaped elastic plates 87 are clamped with the inside of the socket one 84, one side of the strip-shaped handle 88 is fixedly connected with a U-shaped strip 881, the inside of the U-shaped strip 881 is provided with an extrusion surface 883, the extrusion surface 883 is an inclined surface, the surface of the extrusion surface 883 is slidingly connected with a U-shaped push plate 882, and the opposite surfaces of the U-shaped push plate 882 are fixedly connected with anti-disengagement blocks 884, through the setting of the structure, the U-shaped push plate 882 is directly pushed upward during disassembly, and slides on the surface of the extrusion surface 883, because the extrusion surface 883 is inclined, the two L-shaped elastic plates 87 are extruded and deformed and bent, and then the box body 81 is directly disassembled.

[0038] In addition, the setting of the anti-disengagement blocks 884 makes the U-shaped push plate 882 only move up and down, so that the phenomenon of position disengagement is prevented.

[0039] The front and rear sides of the box 81 are provided with circular openings 811 that are open to both the inside and outside. The circular openings 811 facilitate the entry of heat into the box 81 through one circular opening and the exhaust through the other circular opening. The fan 812 consists of a motor and fan blades.

After ensuring that the anti-foolproof notch is aligned, it is inserted vertically and the buckle is fixed.

[0040] Example 3, as Figures 1 to 7 As shown, the U-shaped heat-conducting plate 7 has several interconnected heat dissipation holes 3 71 on the left and right sides of its vertical rear side. The interior of each heat dissipation hole 3 71 corresponds to the heat dissipation hole 2 5. This structure facilitates air circulation. The U-shaped heat-conducting plate 7 has an interconnected opening 72 in the middle of its vertical rear side. The opening 72 facilitates the connection between the internal components of the chassis 1 and different types of interfaces on the rear side of the chassis 1, preventing the U-shaped heat-conducting plate 7 from obstructing the flow of air. The U-shaped heat-conducting plate 7 has an interconnected diamond-shaped opening 73 on the upper front side of its vertical direction. The interior of the diamond-shaped opening 73 corresponds to several heat dissipation holes 1 2. In addition, components can be installed in the U-shaped heat-conducting plate 7. When components are installed on the surface of the U-shaped heat-conducting plate 7, it facilitates the transfer of heat during the operation of the components. The outer surfaces of the U-shaped heat-conducting plate 7 and the heat dissipation assembly 8 are coated with an insulating coating.

[0041] The heat pipe 82, mounting plate 83, fixing plate 85, and U-shaped heat-conducting plate 7 are made of copper, which facilitates heat transfer.

[0042] Example 4, as Figures 1 to 8 As shown, both the upper and lower connecting components 4 include a U-shaped frame 41. A slider 42 is fixedly connected to the rear of the opposite side of the U-shaped frame 41. The outer surface of the slider 42 is slidably connected to the inside of the sliding groove in the side plate 3. This structure facilitates the up and down movement of the U-shaped frame 41. Two insert blocks 43 are fixedly connected to the lower surface of the U-shaped frame 41 in the left and right horizontal directions. A U-shaped limiting block 44 is magnetically inserted into the outer surface of the two insert blocks 43. The magnetic connection ensures stability between the two and prevents easy slippage. The outer surface of the U-shaped limiting block 44 is fixedly connected to the surface of the chassis 1. When the U-shaped frame 41 moves upward, it drives the insert blocks 43 to move, making it easy to separate the U-shaped limiting block 44 and facilitating disassembly.

[0043] By moving the U-shaped frame 41 upward, the second insertion block 43 is separated from the U-shaped limiting block 44, and the U-shaped limiting block 44 is pulled to move the two side plates 3, thereby opening the interior of the chassis 1 for easy maintenance.

[0044] When the box 81 needs to be disassembled and replaced, the L-shaped elastic plate 87 on both sides can be extruded and deformed by pushing the U-shaped push plate 882 upward and sliding on the surface of the extrusion surface 883, and moving the box 81 to separate the surface of the heat conducting pipe 82, the mounting plate 83 and the fixed plate 85, to complete the disassembly and replacement state.

[0045] The above is a detailed description of the general utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the utility model, the modification or improvement is within the scope of the utility model.
