Ultra-supercritical strengthening fluid heat-transferring method and heat-transferring medium

Abstract

The invention discloses a supercritical multiphase enhanced heat transfer method and a heat transfer medium. The method is to add an auxiliary phase change heat transfer material to a basic heat transfer medium, so as to ensure that: when no phase change heat transfer is carried out in the working temperature range of the basic heat transfer medium, the auxiliary phase change heat transfer material carries out phase change heat transfer; when the basic heat transfer medium carries out phase change heat transfer, the auxiliary phase change heat transfer material carries out phase change heat transfer at the phase change temperature lower than a basic phase change heat transfer medium. The method and the medium can realize the integral thermal control and thermal management on heat transfer.

Description

technical field [0001] The invention relates to a heat transfer method using a supercritical fluid, and an ultra-supercritical strong heat transfer medium, which realizes efficient heat transfer by adding an auxiliary supercritical heat transfer medium to the basic supercritical heat transfer medium. Background technique [0002] Using heat transfer medium to transfer heat is the most common way of heat transfer, that is, to use heat transfer medium to absorb heat at the heat source, and make the heat transfer medium after absorbing heat release heat in the heat release device or heat release end, and reach the hot purpose. As a fluid, the heat transfer medium flows in a closed, closed or semi-closed system. This heat transfer method is widely used in industrial fields as well as civil and industrial equipment. [0003] The heat transfer process includes all processes of heat exchange, heat collection, heat dissipation, heat transfer, exchange, collection, storage, applica...
