Abstract

The invention discloses a device for detecting properties of a rotating heat pipe. The device comprises a computer, a signal collecting card, a copper lead wire, and a plurality of heating wires, wherein the copper lead wire and the heating wires are axially and uniformly distributed along the rotating heat pipe and can be in contact with a pipe shell of the rotating heat pipe. The computer is connected with the signal collecting card through a data line; a loop is formed by each heating wire and the copper lead wire through the pipe shell of the rotating heat pipe; a supporting device is fixedly arranged at one ends of the heating wires and the copper lead wire, which are in contact with the pipe shell of the rotating heat pipe; and the other ends of the copper lead wire and the heating wires are respectively connected with the signal collecting card. The device provided by the invention has a simple structure and can rapidly, simply and conveniently detect the heat conduction properties of the rotating heat pipe at a high-speed rotation state.

Description

technical field [0001] The invention relates to a performance detection device of a rotating heat pipe, in particular to a detection device suitable for detecting the heat transfer performance of a rotating heat pipe. Background technique [0002] Heat pipe is a high-efficiency heat transfer element, which can transmit a large amount of heat through its small cross-sectional area for a long distance without external power, so its application range is very wide. The rotating heat pipe is a special heat pipe that uses centrifugal force to replace the capillary force of ordinary heat pipes to drive the working fluid back from the condensation section to the evaporation section. The heat transfer principle of a typical rotating heat pipe is as follows: figure 1 As shown, the inside of the tube shell is a conical working chamber with a cone angle of α. When the rotating heat pipe rotates at a speed of ω, a centrifugal force component ω along the tube wall is generated at the radi...
