Cooling device

Abstract

There is provided a cooling device not affected by gravity by exerting a strong capillary attraction to be hard to deteriorate in transportation function. Unidirectionally-aligned copper fiber assembly 8 is mounted, by a sintering process, on an inner wall of a heat pipe 3 along the longitudinal direction of the heat pipe 3 . Therefore, by a strong capillary attraction caused by fine copper fiber assembly 8 , purified water can be transported without being affected by gravity. A flow volume just enough for the purified water to be prevented from drying out by its evaporation can be maintained, thus making it hard for a function in the transportation of the purified water to be deactivated. Further, the unidirectionally-aligned copper fiber assembly 8 is mounted along the longitudinal direction of heat pipe 3 and hence the purified water smoothly flows in the longitudinal direction of heat pipe 3.
