Fluidized multiphase enhanced heat transfer method and heat transfer medium

Abstract

The present invention discloses one kind of fluidized multiphase forced heat transfer method and heat transfer medium. Auxiliary phase change heat transfer matter is added into base heat transfer medium, so that within the temperature range without phase change heat transfer of the base heat transfer medium, the auxiliary phase change heat transfer matter performs phase change heat transfer, and while phase change heat transfer of the base heat transfer medium, the auxiliary phase change heat transfer matter performs phase change heat transfer under the temperature lower than the phase change temperature of the base phase change heat transfer medium. The said heat transfer method and heat transfer medium makes it possible to realize overall heat transfer control and management.

Description

technical field [0001] The invention relates to a method for enhancing heat transfer by using a fluidized heat transfer medium, and a fluidized strong heat transfer medium, which realizes the overall heat transfer of heat transfer by adding auxiliary phase-change heat transfer substances into the basic heat transfer medium. control and thermal management. 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 dissipati...

[0007] However, due to the high frequency or large amplitude of fluctuations in the ambient temperature or the heat release / absorption in the heat exchange system, by changing the flow rate and operating pressure of the heat transfer medium, there will be hysteresis or insufficient capacity, resulting in heat transfer medium Even when the circulation volume is the largest, the heat to be removed or supplemented cannot be absorbed or released, and the heat exchange capacity is insufficient, which will cause undesirable fluctuations in the temperature of the regulated system or environment, making the purpose of heat transfer impossible. accomplish

The traditional method can ensure that the heat transfer can still be achieved when the heat changes by setting a large heat exchange area margin, but this will increase costs and waste a lot of materials, especially for weight, volume, and cost requirements. Heat transfer, using this method will not be able to achieve the purpose of thermal management and thermal control of heat transfer, such as the thermal management of computer CPU
