A special-shaped heat pipe negative pressure boiling heat removal device

Abstract

The invention discloses a special-shaped heat pipe negative pressure boiling heat removal device, which comprises a heat pipe, a copper pipe and a temperature controller; Vacuum pump, the outer wall of the copper tube is wound and fixedly connected with a heating wire; the upper and lower ends of the heating wire are electrically connected to the temperature controller by forming an electric circuit through the first wire, and the temperature controller is also connected with a signal The temperature sensor is fixedly connected to the outer wall of the copper pipe. In the present invention, the pressure inside the heat pipe rises sharply, but will not exceed normal pressure, and will not cause deformation of the special-shaped heat pipe due to the internal pressure being much greater than the external atmospheric pressure.

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...

Problems solved by technology

[0003] The purpose of the present invention is to provide a special-shaped heat pipe negative pressure boiling heat removal device to solve the existing high-temperature thermal bath method proposed in the above-mentioned background technology, which heats the pre-filled working fluid in the heat pipe to the boiling point under normal pressure. As above, the heat pipe is exhausted, and the non-condensable gas in the pipe is taken away by the ejection of steam, and then sealed with cold welding tongs. Since the temperature of the hot bath is much higher than the normal pressure boiling point of the working fluid in the pipe, heat will be generated after sealing. The pressure in the tube rises sharply, causing the deformation of the heterosexual heat pipe
