Abstract:
A radiation apparatus for dispersing heat energy generated by a heat-generating element, comprising:a first board chamber and a second board chamber; a condenser tube having two ends located respectively on the first board chamber and the second board chamber; an evaporation tube having two ends located respectively on the first board chamber and the second board chamber, the first board chamber, the second board chamber, the condenser tube and the evaporation tube jointly forming a closed space; and working fluid contained in the closed space; wherein the working fluid in the evaporation tube absorbs the heat energy of the heat-generating element to become vapor, the vaporized working fluid flowing through the first board chamber to the condenser tube, the vaporized working fluid dispersing the heat energy previously absorbed in the condenser tube and being condensed to liquid which flows through the second board chamber to the evaporation tube to proceed heat dissipation of a next cycle, and wherein the first board chamber includes a first heat conduction member and a second heat conduction member that are coupled together by soldering.
