Embodiment 1

[0029] The present invention is specifically implemented as follows: as Figure 1-3 The shown MOS tube includes a MOS tube body 1, and the two side walls and the bottom surface of the MOS tube body 1 are provided with limit slots 2; the left wall of the MOS tube body 1 is provided with only one limit slot 2, and the right wall is provided with There are two limit slots 2, so as to play a foolproof effect. The outer side of the MOS tube body 1 is closely attached with a heat dissipation block 3. 3. A heat dissipation fin is formed through the outer surface from left to right. The end surface of the heat dissipation block 3 is close to the end surface of the MOS tube body 1 and a ceramic sheet 5 is provided. The limiting groove 2 extends downward from left to right and extends to the MOS tube body 1. At the position of half the length of the whole, the fastening part 4 of the heat dissipation block 3 is buckled into the half position of the MOS tube body 1, which improves the st...

Embodiment 2

[0040] This example adopts the same structure and preparation process of Example 1. The difference from Example 1 is that the weight components of the adhesive are 4 parts of active agent, 60 parts of latex powder, 6 parts of toner, 4 parts of acrylic resin, and 4 parts of polyacrylic resin. 4 parts of dimethylsiloxane, 4 parts of polyacrylamide, 60 parts of butyl acrylate, 10 parts of acrylic acid, and 7 parts of paraffin wax. It has a good bonding effect at a temperature of 150 degrees.

Abstract

The invention discloses a MOS tube, comprising a MOS tube body, two side walls and a bottom surface of the MOS tube body are provided with limiting grooves; the outer side of the MOS tube body is closely arranged with a heat dissipation block, and the heat dissipation block is provided with a limiter groove. A buckling portion adapted to the position slot, and a ceramic sheet is provided on the end face of the heat dissipation block that is close to the MOS tube body. The invention solves the problems that the MOS tube and the heat dissipation block are poorly fitted and easy to fall, ensure the heat dissipation efficiency of the MOS tube, and improve the service life of the MOS tube.

Description

technical field [0001] The invention relates to the technical field of electronics, in particular to a MOS tube and a preparation method thereof. Background technique [0002] MOS tube is often used in inverter power supply, solar controller, discharge instrument, UPS power supply and other products, especially high-power power supply products need to use MOS tube, and MOS tube is a power device, the temperature of normal workpiece is very high, It is necessary to use a heat sink to dissipate heat for the MOS tube, but the traditional MOS tube and the heat sink cannot fit well, and they are easy to fall off and unreliable, resulting in low heat dissipation efficiency of the MOS tube, and the long-term heating of the MOS tube will seriously affect the MOS tube. service life. SUMMARY OF THE INVENTION [0003] The present invention aims to solve the above-mentioned technical problems to a certain extent, and provides a MOS tube, which solves the problems of poor fit and easy...
