Abstract
Inner peripheral grooves for transporting a liquid of a working fluid in the longitudinal direction of a first wick are provided along the first wick which transports the liquid contained in the evaporator to a heating portion in the evaporator by capillary force, and a liquid supply portion for supplying the liquid of the working fluid is further provided to the inner peripheral grooves. Therefore, the liquid of the working fluid can be efficiently supplied to the inner peripheral surface of the first wick with a simple structure, so that a loop type heat pipe which can be constantly stably operated can be obtained.
