Abstract
A cooling device which is provided with an evaporator with a built-in wick, a condenser, and a loop type heat pipe which connects the evaporator and condenser in a loop and is provided with a liquid pipe and vapor pipe, wherein the evaporator is divided into a liquid-pipe-side case and a vapor-pipe-side case and wherein a plurality of discharge ports of working fluids and a wick in which the working fluid from the discharge ports is completely permeated are arranged between the two cases. The wick is provided with projecting parts which have recessed parts corresponding to the discharge ports, while the outer circumferential surfaces of the projecting parts are provided with grooves. The working fluid which permeates the wick is changed to a vapor inside the vapor-pipe-side case, collects in the evaporation chamber, and is discharged to the liquid pipe, and thus, dry out of the wick is prevented.
