Abstract

The invention discloses an automatic heat dissipation capacitor for preventing welding heat damage, which comprises a core package, the core package is covered with a hollow metal casing, and a plurality of annular hollow fins are arranged on the side wall of the hollow metal casing , the socket plug of the hollow metal casing is provided with a sealing cover, and two mounting grooves are symmetrically opened on the lower end of the sealing cover. The invention solves the problem of thermal damage or shortened service life of the core pack caused by overheated welding or long welding time of the capacitor through the insulation and heat conduction sleeve, the hollow wall heat conduction tube and the evaporation, condensation and heat dissipation of the refrigerant, and the electromagnetic box attracts the magnetic piston ring to push the refrigerant into The hollow metal casing solves the problem of heat dissipation of the capacitor.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an automatic heat dissipation capacitor for preventing welding heat damage. Background technique [0002] In the power system, the capacitor is one of the essential power devices, and the capacitor plays an important role in tuning, bypassing, coupling, filtering and other circuits. [0003] Existing capacitors are usually composed of an aluminum shell, a core package, a rubber plug and a lead rod. The lead rod is usually a metal material with good electrical conductivity, and its thermal conductivity is usually relatively good. Therefore, the capacitor is soldered to the During the process in the circuit, the temperature of the welding torch is too high, and the welding time is too long, so that the high temperature is transmitted to the core package through the pin rod, causing damage to the capacitor or shortening the service life. Contents of the invention [0004] The pu...
