Abstract

The utility model relates to a heat pipe radiator used for solving the heat dissipation problem of the power module device in the electric power and electronic industry, comprising a heat pipe, a heat dissipation fin, an evaporating box and a baseboard. The heat pipe is a U-shaped heat pipe outside which the heat dissipation fin is sheathed. The aperture part of the U-shaped heat pipe is inserted into the evaporating box hole which is matched with the diameter of the heat pipe. The baseboard for sealing the evaporating box is arranged on the other face of the evaporating box. The U-shaped heat pipe and the cavity in the evaporating box constitute an annular circuit. The above components comprises a heat pipe radiator unit used by the power module device. The heat pipe radiator is composed of one heat pipe radiator unit or multiple heat pipe radiator units. The utility model has the advantages of good radiation effect, low cost, small volume, small heat resistance, no noise and pollution, dependable performance and safe in operation.
