Insulation heat pipe radiator of explosive-proof structure

Abstract

The invention discloses an insulation heat pipe radiator of an explosive-proof structure. The insulation heat pipe radiator comprises an explosive-proof shell. An internal heat pipe insulation heat radiating device is arranged in an internal space of the explosive-proof shell and comprises a heat conduction base plate. A base plate hole is formed inside the heat conduction base plate, and the direction of the base plate hole is consistent with the stretching direction of the heat conduction base plate. A heated end of an internal heat pipe penetrates through the base plate hole. The heat radiating end is fixed to the inner wall of the explosive-proof shell or penetrates through the explosive-proof shell. A heat conduction insulation material and an insulation monitor are arranged between the base plate hole and the heated end of the internal heat pipe. The heat conduction base plate and the internal heat pipe can transfer heat and are mutually insulated through the heat conduction insulation material. The insulation monitor is used for detecting the insulation performance of the heat conduction insulation material. An external heat pipe heat radiating device is arranged outside the explosive-proof shell or an explosive-proof shell heat radiating device is arranged on the shell wall of the explosive-proof shell. The insulation heat pipe radiator of the explosive-proof structure can meet the heat radiating, insulation and explosive-proof requirements, and can be popularized and applied to a high-voltage electric transmission device in the explosive-proof field.

Description

technical field [0001] The present invention relates to the technical field of radiators, in particular to a radiator of an insulating heat pipe with an explosion-proof structure. Background technique [0002] As a heat-conducting element with extremely high thermal conductivity, the heat pipe transfers heat through the vapor and liquid phase change of the medium in the vacuum tube with a certain degree of vacuum at a fully enclosed normal temperature, and has extremely high thermal conductivity; generally, the heated end of the heat pipe is called The hot end and the heat dissipation end are called the cold end. Heat sinks with heat pipes as the core have been widely used in the heat dissipation of power semiconductors. With the development of electric transmission technology using power semiconductors as power devices, medium and high voltage electric transmission devices have become popular. However, due to the limitation of the insulation level of the power semiconduct...

Problems solved by technology

However, due to the limitation of the insulation level of the power semiconductor device itself, the application of medium and high voltage electric transmission devices in some industries is also limited; because the outer shell of the heat pipe is a closed metal structure, which is a good conductor, the current flameproof equipment used The heat pipe radiator cannot meet the insulation requirements of medium and high voltage electric transmission devices, which limits the promotion of medium and high voltage electric transmission devices
