Description

Technical Field

[0001] The utility model relates to the technical field of aluminum substrates, in particular to a flexible spliced ​​aluminum substrate with high thermal conductivity. Background Art

[0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided board is composed of a three-layer structure, namely a circuit layer (copper foil), an insulating layer and a metal base layer. Very few applications are multi-layer boards, which can be made of ordinary multi-layer boards, insulating layers, and aluminum bases.

[0003] The existing aluminum substrate can only be used normally, but has poor performance. After long-term use, the heat dissipation is poor. In a small space, if the aluminum substrate is too large, it will not be easy to install. Therefore, a flexible splicing aluminum substrate with high thermal conductivity is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a flexible spliced ​​aluminum substrate with high thermal conductivity, which has the advantages of strong practicality and simple operation, and solves the problem that the aluminum substrate has poor heat dissipation after long-term use and is inconvenient to install.

[0005] To achieve the above object, the utility model provides the following technical solution: a flexible spliced ​​aluminum substrate with high thermal conductivity, comprising an aluminum substrate, a frame fixedly connected to the outer surface of the aluminum substrate, a heat sink fixedly connected to the front of the aluminum substrate, three air holes opened inside the heat sink, and a fixing device fixedly connected to the outer surface of the frame;

[0006] The fixing device includes a connecting rod fixedly connected to the top and bottom of the frame, the two connecting rods are fixedly connected to a connecting seat on the left side, the two connecting seats are fixedly connected to a spring box on the left side, the two spring boxes are fixedly connected to springs inside, the two springs are fixedly connected to a clamping rod at the bottom, the two clamping rods are fixedly connected to movable wheels, the top and bottom of the frame are fixedly connected to clamping blocks, the two clamping blocks are provided with clamping grooves inside, and the two clamping grooves are fixedly connected to convex inclined blocks inside.

[0007] Furthermore, limiting grooves are provided inside the two spring boxes, limiting rings are fixedly connected to the outer surfaces of the two clamping rods, and the two limiting rings are located inside the limiting grooves.

[0008] Furthermore, telescopic holes are provided at the top and bottom of the two spring boxes, and the two clamping rods are movably connected to the inside of the telescopic holes.

[0009] Furthermore, the top and bottom shapes of the two spring boxes are both arc-shaped, and the shapes of the two connecting rods are both 7-shaped.

[0010] Furthermore, the number of the heat sinks is four and they are evenly distributed on the front side of the aluminum substrate.

[0011] Furthermore, the number of the heat dissipation holes is twelve, and the shapes of the heat dissipation holes are all circular.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The flexible splicing aluminum substrate with high thermal conductivity is convenient for air circulation by fixing heat sinks and air holes on the front of the aluminum substrate, which effectively dissipates heat from the aluminum substrate body. When splicing is required, the two aluminum substrates can be placed left and right, and the right aluminum substrate can be moved to the left. When the spring box moves to the convex inclined block, the clamping rod and the movable wheel will shrink. When it moves to the leftmost side of the card slot, the spring will reset the clamping rod and the movable wheel, thereby fixing and clamping the two aluminum substrates.
