Rapid thyristor capable of dissipating heat

Abstract

The invention discloses a rapid thyristor capable of dissipating heat, a wiping heat dissipation mechanism comprises a lifting frame and symmetrically arranged heat exchange plates, thermal inductance plates are embedded and fixedly connected to the outer surfaces of the two heat exchange plates, and the sides, close to each other, of the outer surfaces of the two thermal inductance plates are fixedly connected with the outer surface of the thyristor. According to the rapid thyristor capable of dissipating heat, through the arrangement of the wiping heat dissipation mechanism, when the temperature rises, the resistance in the thermal inductance plate changes, and the servo motor drives the screw rod to rotate forwards and backwards, so that the lifting frame drives the wiping plate to move up and down in a reciprocating manner, and evaporated liquor contained in the wiping plate is smeared on the heat exchange plate; therefore, the heat dissipation efficiency is improved, the thyristor can be rapidly cooled, internal elements are prevented from being damaged by high temperature, and the problems that the thyristor is low in natural heat dissipation efficiency and cannot be cooled in time, so that parts are easily damaged or the service life is shortened are solved through the combination of the structures.

Description

technical field [0001] The invention relates to the technical field of thyristors, in particular to a fast thyristor capable of dissipating heat. Background technique [0002] Thyristor, also known as silicon-controlled rectifier, was once referred to as thyristor; thyristor is a PNPN four-layer semiconductor structure, which has three poles: anode, cathode and gate; the working conditions of thyristor are: plus forward voltage and The gate has a trigger current; its derivative devices include: fast thyristor, bidirectional thyristor, reverse conduction thyristor, light-controlled thyristor, etc. [0003] Thyristors tend to generate heat during use, which makes the components heat up and heat up. Generally, thyristors are cooled by natural heat dissipation. However, when the temperature is high and the heat lasts for a long time, it is easy to cause damage to the thyristor or reduce the service life. Therefore, it is necessary to address the above problems to solve. Conte...
