Combined MOS (Metal Oxide Semiconductor) tube structure with good insulating property

Abstract

The invention relates to the technical field of MOS tubes, and discloses a combined MOS tube structure with good insulation performance, which comprises an insulation shell, side boxes are fixedly connected to the two sides of the insulation shell, rolling balls are movably connected to the interiors of the side boxes, sliding tooth frames are slidably connected to the inner walls of the side boxes and located on the two sides of the rolling balls, and the inner walls of the sliding tooth frames are fixedly connected with the insulation shell. And the surface of the sliding tooth frame is meshed with a half gear, the interior of the half gear is fixedly connected with a fan shaft, the interior of the insulating shell is provided with a dehumidification and dust removal mechanism, and the interior of the insulating shell is fixedly connected with a filter screen. According to the combined MOS tube structure with the good insulating property, the rolling balls are driven to move left and right in the side box through the movement force generated when an automobile is started, the rolling balls impact the sliding tooth frame and move to drive the fan shafts on the half gears to rotate, air cooling is generated in the insulating shell, and the heat dissipation effect on the combined panel is achieved; and the problem that the service life of the element is damaged due to heat accumulation during operation of the combined MOS structure is avoided.

Description

technical field [0001] The invention relates to the technical field of MOS tubes, in particular to a combined MOS tube structure with good insulation performance. Background technique [0002] MOS tube is a field effect tube. It adopts a crystal triode with an insulated gate structure. It has high input impedance and a resistive output. It is now widely used, including TV tuners to switching power supplies. Now it is combined with MOS and bipolar, and it is widely used. In the field of high power, the application of MOS tube is indispensable in the operation of automobiles. In order to ensure its good insulation performance, an insulating shell is usually added to the combined MOS tube plate for protection. [0003] In order to ensure the insulation performance of the existing combined MOS structure, the protection of the relatively sealed state leads to poor heat dissipation performance. The combined MOS structure accumulates a lot of heat during operation, resulting in dam...

[0003] In order to ensure the insulation performance of the existing combined MOS structure, the protection of the relatively sealed state leads to poor heat dissipation performance. The combined MOS structure accumulates a large amount of heat during operation, resulting in damage to the life of the internal components. Therefore, a combination with good insulation performance is proposed. Type MOS tube structure to solve the problems raised above
