PURPOSE:To permit sufficient heat dissipation by small sized fins by a method wherein a bellows is utilized as the container of the heat pipe and a cord-like wick is intersected with the group of grooves orthogonally, in the small sized radiator for the substrate of a semi-conductor circuit. CONSTITUTION:The container 11 is consists of the bellows utilized for the heat dissipating fins in combination and will never buckle by a high vacuum even through the thickness thereof is made very thin. Accordingly, heat exchange between airstream and operating vapor may be effected in a very short period of time since it is effected through a thin container wall having 0.08-0.18mm.. The wick 14 is intersected with the grooves of the bellows by an elastic wick supporting body 16 and is pressingly supported along the transversal direction of the bellows, therefore, it maintains heat exchanging capacity. Further, the thicknesses of a heat absorbing surface 13 and a heat dissipating surface 12 are permitted to make them thin, since the container 11 is the bellows and the bellows itself can resist a high pressure. Thus, the thickness of the wall of the heat transmitting surface may be made thin, therefore, a sufficient heat dissipating effect and a sufficient interior volume may be obtained. |
