Abstract

The invention provides a flat double-face phase-change restraining heat conducting board structure and a manufacturing method thereof. The flat double-face phase-change restraining heat conducting board structure is a composite board type structure. The surface of the flat double-face phase-change restraining heat conducting board structure is a plane. Heat superconducting pipelines which are in a specific shape and are communicated with one another are arranged in the flat double-face phase-change restraining heat conducting board structure. The heat superconducting pipelines are closed pipelines and are filled with a heat conducting working medium. Groove channels communicated with one another are formed in the heat conducting board structure with the double faces being planes and the groove channels are filled with the heat conducting working medium and closed, so that the characteristics that the heat conducting speed is high and the temperature uniformity is good for phase-change restraining heat conduction are achieved. The double faces of the phase-change restraining heat conducting board structure are designed to be the planes so that the structure can be well combined with a high-power device and a cooling fin set, and application occasions and the range of a phase-change restraining heat conducting board can be expanded greatly. A blowing and expanding process is adopted to obtain the flat double-face board structure with the internal groove channels, and the structure has the characteristics of being low in cost, easy to machine and high in reliability.

Description

technical field [0001] The invention belongs to the field of heat transfer, and in particular relates to a double-sided planar phase transition suppressing heat transfer plate structure and a manufacturing method thereof. Background technique [0002] Phase Change Inhibition (PCI) heat transfer technology is a new technology that achieves efficient heat transfer by controlling the microstructure of the heat transfer medium in a closed system. During the heat transfer process, the boiling of the liquid medium (or the condensation of the gaseous medium) is suppressed, and on this basis, the consistency of the microstructure of the working medium is achieved, realizing a new heat transfer method that has not been recognized by the world and mechanism. With high heat transfer rate and high heat flux, the heat flux tested in the laboratory can be as high as 600W / cm 2 . It can be widely used in industries such as aerospace, power electronics, communications, computers, high-spe...
