Abstract

The invention provides an integrated flat single-face phase-change restraining heat conducting board type heat exchanger and a manufacturing method thereof. The heat exchanger comprises a heat exchange board of a composite board type structure. One surface of the heat exchange board is a plane. A refrigerant channel of a specific structure in a specific shape and a heat superconducting pipeline of a specific structure in a specific shape are formed in the heat exchange board. The heat superconducting pipeline is a closed pipeline and is filled with a heat conducting working medium. The heat superconducting pipeline and the refrigerant channel are combined together in the heat exchange board of the integrated flat single-face phase-change restraining heat conducting board type heat exchanger and the heat superconducting pipeline is filled with the heat conducting working medium, so that a phase-change restraining heat conducting device is formed, the heat exchanger has the characteristics of being high in heat conducting speed and good in temperature uniformity, the temperature difference of the heat exchange board and air is increased, the effective heat conducting area is broadened, and the heat dissipation capacity and the heat exchange efficiency are improved. The heat exchanger has the beneficial effects of being uniform in temperature and capable of exchanging heat efficiently, the length of the refrigerant channel is greatly reduced, flow resistance, energy consumption and the use amount of fluid are reduced, and therefore the efficiency of the heat exchanger is improved and the energy efficiency ratio of the heat exchanger is increased.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to an integrated single-sided plane phase transition suppressing heat transfer plate heat exchanger 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 / cm2. It can be widely used in industries such as aerospace, power electronics, communications, computers, high-speed rail, ...

AI Technical Summary

Problems solved by technology

[0007] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an integrated single-sided plane phase transition suppressing heat transfer plate heat exchanger and its manufacturing method, which is used to solve the problems in the prior art due to the thermal conductivity of aluminum materials. Due to the limitation of thickness and thickness, the heat conduction resistance is large, and the refrigerant channel cannot cover the entire surface of the plate, so the temperature of the entire plate surface of the heat exchanger composite plate is uneven, and there is local overheating or overcooling, and the entire evaporator cannot be fully utilized. The heat exchange area, and because the piping system is too long, the flow resistance of the fluid in the pipes in the heat exchange plate is very large, resulting in the reduction of the energy efficiency of the system
