A high-speed axially rotating heat pipe performance testing device and its working method

Abstract

The invention discloses a high-speed axially rotating heat pipe performance testing device and a working method thereof, which relate to the technical field of rotating heat pipe experiments, can avoid the use of a slip ring device, and accurately measure the working fluid inside the heat pipe under high-speed operating conditions temperature. The invention includes: a rotating device, a heating device, a cooling device, a wireless temperature measuring device, a rotating heat pipe to be tested, and an experiment stand. The rotating device drives the rotating heat pipe to rotate at high speed. The heating device provides stable and controllable heat flux density to the evaporation section of the heat pipe by means of induction heating. The cooling device sprays and cools the condensing section of the heat pipe. The temperature is measured directly and the measurement result is transmitted to an external receiving device. The invention can simultaneously measure the heat received in the evaporating section of the heat pipe and the heat dissipation in the condensing section, thereby ensuring the accuracy and reliability of the experiment.

Description

technical field [0001] The invention relates to the technical field of rotating heat pipe experiments, in particular to a high-speed axially rotating heat pipe performance testing device and a working method thereof. Background technique [0002] High-speed motors (above 10,000rpm) will be key components of future new energy vehicles, high-end CNC machine tools, electric propulsion aircraft and other equipment. However, high-speed motors are small in size, high in power density and loss density, and the heat dissipation of the rotor is very difficult, which also restricts the development and application of high-speed motors. Axially rotating heat pipes have a simple structure and good heat transfer performance. They have been used to cool some rotating machines with low and medium speeds, and are expected to be applied to cooling high-speed motors. However, the current experimental research on rotating heat pipes is concentrated in the low and medium speed range, so it is n...
