Special-shaped heat pipe negative pressure boiling heat discharge device

Abstract

The invention discloses a special-shaped heat pipe negative pressure boiling heat discharge device. The special-shaped heat pipe negative pressure boiling heat discharge device comprises a heat pipe,a copper pipe and a temperature controller, the lower end of the heat pipe is placed in the copper pipe, the top end, located above the outer side of the copper pipe, of the heat pipe communicates with a vacuum pump through a connecting pipe, a heating wire is fixedly connected to the outer side wall of the copper pipe in a wound mode, the upper end and the lower end of the heating wire form an electric loop through a first wire to be electrically connected with the temperature controller, the temperature controller is further in signal connection with a temperature sensor, and the temperaturesensor is fixedly connected to the outer side wall of the copper pipe. According to the special-shaped heat pipe negative pressure boiling heat discharge device, pressure in the heat pipe rises sharply, but does not exceed the atmospheric pressure, and the deformation of a special-shaped heat pipe caused by the fact that internal pressure is far larger than external atmospheric pressure is avoided.

Description

technical field [0001] The invention relates to the technical field of special-shaped heat pipe heating, in particular to a special-shaped heat pipe negative pressure boiling heat removal device. Background technique [0002] The heat pipe makes full use of the principle of heat conduction and the rapid heat transfer properties of the phase change medium. Through the heat pipe, the heat of the heating object is quickly transferred to the outside of the heat source. Its thermal conductivity exceeds that of any known metal. The existing method is a high-temperature heat bath. , heat the pre-filled working fluid in the heat pipe to above the boiling point at normal pressure, exhaust the heat pipe, take away the non-condensable gas in the pipe by the ejection of steam, and then seal it with cold welding pliers. The temperature is much higher than the normal pressure boiling point of the working medium in the tube. After sealing, the pressure in the heat pipe will rise sharply an...
