A flameproof structure insulating heat pipe radiator

Abstract

The invention discloses an insulated heat pipe radiator with a flameproof structure, which comprises: a flameproof casing, an internal heat pipe insulation and heat dissipation device is arranged in the inner space of the flameproof casing, the internal heat pipe insulation and heat dissipation device includes a heat conduction substrate, and the heat conduction substrate There is a substrate hole in the same extending direction inside the inner heat pipe, the heated end of the internal heat pipe is penetrated in the substrate hole, and the heat dissipation end is fixed on the inner wall of the flameproof casing or passes out of the flameproof casing; between the substrate hole and the inside A thermally conductive insulating material is provided between the heated ends of the heat pipe to enable heat transfer and mutual insulation between the thermally conductive substrate and the internal heat pipe, and an insulation monitor to detect the insulation performance of the thermally conductive insulating material. An external heat pipe cooling device is provided outside the flameproof casing or a flameproof casing cooling device is arranged on the shell wall of the flameproof casing. The flameproof structure insulating heat pipe radiator of the invention can simultaneously meet the requirements of heat dissipation, insulation and flameproofing, and can be popularized and applied in flameproof medium and high voltage electric transmission devices.

Description

technical field [0001] The invention relates to the technical field of heat sinks, in particular to a heat pipe heat sink with flameproof structure insulation. Background technique [0002] As a heat-conducting element with extremely high thermal conductivity, the heat pipe transfers heat through the vapor-liquid phase change of the medium in the vacuum tube with a certain degree of vacuum at room temperature in a fully enclosed room, and has extremely high thermal conductivity; the heating end of a general heat pipe is called The hot end and the cooling end are called the cold end. Heat sinks with heat pipes as the core are 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 semiconductor device itself, the application of ...

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
