Description

technical field [0001] The invention relates to a preparation method of a superconducting heat pipe and a heat transfer medium thereof. Background technique [0002] In the prior art, a superconducting heat pipe is used, which is a metal tube whose two ends are closed and a heat transfer medium is stored in the inner cavity. The heat transfer medium of existing conventional heat pipes is mainly liquid organic compounds such as water, oil, ethanol, etc., and the conventional steel pipe-water medium heat pipe can work in the temperature range of 30-200 degrees Celsius, and has a relatively high heat transfer efficiency. applications in some industrial sectors. However, when the organic medium heat pipe is working, there is a large pressure in the pipe, and the pressure is closely related to the temperature. If the temperature is too high, the pipe will burst, and the organic material will produce unstable gas H 2 , so that the heat transfer coefficient is reduced; the organi...
