Abstract

A flat plate heat transfer device contacted with heat source and heat-emitting unit at both end transfers heat generated at the heat source to the heat-emitting unit horizontally. The device includes a thermally-conductive flat case containing a working fluid evaporated with absorbing heat from the heat source and condensed with emitting heat to the heat-emitting unit; and a mesh aggregate installed in the case so that coarse and fine meshes in which wires are woven to be alternately crossed up / down are vertically laminated in contact. The coarse mesh gives main-directional and sub-directional vapor dispersion channels with different sectional areas at each crossing point of the mesh wires for vapor to flow therethrough. The main-directional vapor dispersion channel with relatively larger sectional area is parallel to heat transfer direction. The fine mesh gives liquid flow channels along running direction of the mesh wire from each crossing point of the mesh wires.

Description

TECHNICAL FIELD

[0001] The present invention relates to a flat plate heat transfer device capable of emitting heat from a heat source by circulating a working fluid using evaporation and condensation and its manufacturing method, and more particularly to a flat plate heat transfer device capable of preventing crush of a flat case and giving vapor dispersion channels and liquid flow channels in a direction that ensures a maximum heat transfer efficiency and its manufacturing method. BACKGROUND ART

[0002] In recent, an electronic equipment such as notebook or PDA becomes smaller and thinner along with the development of integration technique. In addition, together with the increased demands for higher responsiveness of an electronic equipment and improvement of functions, energy consumption is also tending increased. Accordingly, much heat is generated from electronic components in the electronic equipment while the equipment is operated, so various flat plate heat transfer devices ar...
