<P>PROBLEM TO BE SOLVED: To improve a cooling function of a heat pipe, and to prevent lowering of the cooling function of the heat pipe due to the generation of scattering by moving the operating fluid inside of a heat pipe without using the capillary tube pressure. <P>SOLUTION: In this heat pipe provided with a heat absorption part for absorbing the heat from a heating part, a heat radiation part for radiating the heat to cool an inside space, and a container, and formed by sealing the operating fluid and the steam generated by evaporation of the operating fluid in the inside space of the container, a plurality of projection parts are provided in the inner surface of the container to form grooves between the projection parts. Furthermore, the grooves are filled with the operating fluid, and shape of the groove is set so that width of the groove on a side thereof facing to a passage of the steam is larger than height of the groove. Furthermore, plate-like partition plates formed from a non-permeable material are provided in the inside space of the container so that the partition plates abut on the top of the projection parts or come close to the projection parts. <P>COPYRIGHT: (C)2004,JPO |
