Abstract

The loop heat conducting equipment includes vaporizer and condenser connected to each other through circle pipe so as to constitute circulation loop of liquid working medium. The vaporizer possesses core body of capillary structure (CBCS) inside. Multiple tunnels are formed in CBCS. One end of tunnels is converged to vapor chamber, which is connected to one end of the circle pipe to form the output end of gas state working medium. After through the condenser, the other end of the circle pipe as the input end of formed liquid working medium is connected to the vaporizer. Extending into and contacting with inner CBCS, end of the circle pipe forms compensated chamber of liquid working medium on up portion of CBCS. Using gas and liquid separated circulation loop, the invention reaches optimalefficiency of heat elimination. Features are: simple structure, and easy of measure yield.

Description

technical field [0001] The invention relates to a heat conduction device, in particular to a loop heat conduction device. The evaporator and the condenser are connected through a ring pipe to form a circulation circuit of a fluid working medium. The evaporator is provided with a steam chamber and a compensation chamber. liquid separation to achieve the best heat dissipation efficiency. Background technique [0002] With the rapid development of technology and the rapid development of electronic products, under the trend of lightness, thinness, shortness, smallness and refinement, and the requirements for performance are getting higher and higher, the corresponding power used must be higher and higher. In this way, as the volume becomes smaller and the power becomes larger, the heating density on the surface of the electronic components will increase rapidly, and the corresponding heat treatment problem will become very difficult. The heat accumulation effect in high-power c...
