Technical Field

Background

Transistors are an important electronic component that plays an irreplaceable role in the control circuit. The transistor is made of semiconductor materials and is sensitive to temperature, and as the transistor operates, the transistor heats up to enable the temperature of the transistor to rise, so that the transistor is excessively high in temperature to enable the performance of the transistor to be seriously affected, and therefore, the improvement of heat dissipation of the transistor is an important means for ensuring the normal operation of the transistor.

As shown in fig. 1, the conventional heat dissipation method of the transistor is to fix the transistor 2 to the surface of the heat sink 1, wherein one side of the transistor 2 is tightly attached to the surface of the heat sink 1, the transistor 2 is fixed to the surface of the heat sink 1 by screws, and the surface of the heat sink 1 contacting with the transistor 2 is coated with glue to improve the contact tightness of the heat sink and the transistor 2. When the transistor 2 is in operation, heat generated by the transistor 2 can be conducted to the radiator 1 in a heat transfer mode, and the heat is radiated through the radiator 1, so that a good heat radiation and cooling effect is achieved on the transistor 2.

In the conventional assembly mode, the assembly between the transistor 2 and the radiator 1 adopts a manual operation mode, an operator needs to coat glue on the position of the radiator where the transistor 2 is mounted, then place the transistor 2 on the radiator where the glue is coated, and finally screw a screw between the transistor 2 and the radiator 1; screw holes are reserved in the radiator, and screws penetrate through the through holes 21 in the transistor 2 and then are screwed into the screw holes in the radiator 1, so that the transistor 2 is fixed.

The existing assembly mode depends on manual operation, is time-consuming and labor-consuming, has high labor cost and low assembly efficiency, and is difficult to meet mass production requirements.
