The bottom surface of the fixing block 51 is provided with a screw hole for mounting and fixing the fixing block 51. As shown in fig. 1, the present invention can be mounted on a plate by means of screws. As shown in fig. 1, 10 is a fixing plate, and 11 is a screw. The fixing block 51 may be fixed by a screw.
The heat conduction device is a cuboid made of heat conduction materials. One of the two opposite surfaces is fixedly connected with the expansion board 10, and the other surface is adhered with a heat-conducting adhesive tape for increasing the heat conduction efficiency with the chip. The heat conducting material can be aluminum oxide heat conducting rubber, boron nitride heat conducting rubber or copper aluminum and other metal materials.
The sectional shape of the slider 52 is set according to the size of the chip. The chip is generally rectangular and thus slider 52 may be rectangular. The sliding block 52 is inserted into the sliding slot 511, so the cross-sectional shape of the sliding slot 511 should be the same as the cross-sectional shape of the sliding block 52. In order to maintain close contact between the slide block 52 and the chip, a spring 53 is provided between the slide block 52 and the bottom of the slide slot 511. After mounting and fixing, the sliding block 52 is always tightly attached to the chip under the action of the elastic force of the spring 53, so that good contact can be ensured.

Preferably, the heat-conducting silicone grease is coated inside the heat-conducting groove 521.
Preferably, the slide block 52 is not separated due to the chip being stopped in the use state, but the slide block 52 is easily separated in maintenance or disassembly, and therefore a stopper is provided between the fixed block 51 and the slide block 52. The method specifically comprises the following steps:
the side of the sliding block 52 is provided with a limit groove 522. A limiting block 514 is arranged at the notch of the sliding groove 511 of the fixing block 51 corresponding to the limiting groove 522.
