Abstract

The invention relates to a superconductor heat pipe and a preparation method of a heat transfer medium thereof. The superconductor heat pipe comprises a metal pipe, wherein both ends of the metal pipe are sealed, the heat transfer medium is stored in an inner cavity of the metal pipe, and the inner cavity of the metal pipe is vacuumized. The heat transfer medium comprises the following raw materials in percentage by weight: 3-5g of boric acid, 50-60g of potassium dichromate, 8-10g of sodium perborate, 1-3g of calcium chloride, 1-3g of sodium dioxide, 1-3g of manganese dioxide, 1-1.5g of dihydroxyaluminum, 1-5g of sodium chloride and 1000g of water. The preparation method of the heat transfer medium comprises the following steps of: adding the raw materials into mild water at 80 DEG C sequentially; and dissolving by evenly stirring continuously at the same time. The superconductor heat pipe has quick heat transfer, high heat transfer efficiency and good energy-saving effect, and the heat transfer medium has stable chemistry, larger heat conductivity coefficients, good compatibility with pipes, non corrosiveness and convenient preparation method.

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...

Problems solved by technology

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 organic medium is incompatible with the pipe, and non-condensable gas is produced to corrode the pipe wall and reduce the service life of the heat pipe
