Silicon controlled rectifier radiator with temperature sensor

Abstract

The invention discloses a silicon controlled rectifier radiator with a temperature sensor. The silicon controlled rectifier radiator comprises a cylindrical device body and two cylindrical outer handles; the surface of the cylindrical device body comprises an inner core groove matched with a silicon controlled rectifier; the diameter of the inner core groove is the same as the external diameter ofthe silicon controlled contact surface; the cross section of the inner core groove in a certain direction is circular, and an ejector pin is matched with a pit in the circle center of the silicon controlled rectifier; the two cylindrical outer handles are located on the outer side surface of the device body, and a negative temperature coefficient thermistor is welded to the surface of the inner core groove in the right side of the ejector pin through soldering tin. According to the silicon controlled rectifier radiator with the temperature sensor, the middle of the silicon controlled rectifier radiator integrally sinks for 0.4-0.7 mm to form an inner core groove matched with the diameter of a silicon controlled rectifier silicon type radiating surface; due to the fact that the inner coregroove is formed, the ejector pin is not prone to abrasion, thereby guaranteeing accurate center positioning as long as the silicon controlled rectifier is placed in the inner core groove during installation or maintenance, shortening the calibration positioning time, and improving reliability and working efficiency.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a thyristor radiator with a temperature sensor. Background technique [0002] Thyristor intermediate frequency power supply adopts international advanced ISP industrial module control, full digital calculation, reliable hardware and software protection, more complete functions, suitable for metal smelting, heat preservation, diathermy, metal heat treatment, quenching, sintering and other occasions. The load consists of an induction coil and a compensation capacitor connected as a parallel resonant circuit. The basic working principle of the thyristor intermediate frequency power supply is to rectify the 50Hz power frequency AC current into DC through a three-phase bridge rectifier circuit, and then pass through a filter (DC reactor) for filtering, and finally pass through the inverter. The DC becomes a single-phase intermediate frequency AC to supply the load, so this inverter...

Problems solved by technology

In the production process, because the diameter of the thimble is only 1-2mm, and the height is 0.5-1mm, it is easy to deviate from the center during pressing, resulting in poor contact of the heat dissipation surface, affecting the heat dissipation effect, and easily damaging the thyristor.

If the thyristor needs to be replaced for maintenance, part of the connecting copper bar must be removed. If the thimble of the radiator is worn, the positioning will be difficult and the center will easily deviate, resulting in damage to the thyristor. There is a serious shortage, and the radiator itself cannot be controlled. temperature
