Abstract

A supporting column having a porous structure is installed in a chamber filled with working fluid. The chamber includes an evaporation side for evaporating the working fluid to the gaseous phase, and a condensation side opposite the evaporation side for condensing the gaseous phase to the liquid phase. The supporting column includes a supporting body and the porous structure formed on the supporting body. Two ends of the supporting body are connected to the evaporation side and the condensation side respectively. The porous structure is supported by the supporting body and configured to convey the working fluid. Accordingly, heat dissipation is achieved by phase cycling of the working fluid.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a supporting column, and more particularly, to a supporting column having a porous structure and installed in a chamber filled with working fluid, thus conveying the working fluid with a view to achieving heat dissipation.

[0003] 2. Description of Related Art

[0004] In 1963, G. M. Grover invented heat pipe technology. A heat pipe is a heat transmitting device based on the principles of heat transfer as well as a property of cooling media—rapid heat transfer. A heat pipe is typically fully-sealed and vacuum-maintained so as to facilitate rapid heat transfer through evaporation and condensation. It has other advantages, namely adjustable heat transfer areas on both the cold and hot interfaces, long-distance heat transfer, and controllable temperature. A heat exchanger composed of heat pipes has advantages, such as efficient heat transfer, compact structure, and low flow impedance. Accordingly,...
