Abstract
A heat-pipe device for transferring heat generated by a heat-generating element, having at least one heat-pipe body which is an extrudate of plate-like configuration made of aluminum or its alloy, the heat-pipe body including a planer-structure portion which has on one side thereof a flat face to which the heat-generating element is directly fixed, the heat-pipe body further including a plurality of passage-defining portions which protrude from the other side of the planer-structure portion and extend parallel to, and apart a predetermined distance from, each other, each passage-defining portion having therein a flow passage which is fluid-tightly charged with a working fluid for transferring the heat generated by the heat-generating element. Also is disclosed a heat-sink device for cooling a heat-generating element, having at least one heat-pipe body including a planer-structure portion and a plurality of passage-defining portions. The heat-sink device may further have a header pipe, and the heat-pipe body may be bent to form a box-like configuration such that the longitudinal ends of flow passages within the passage-defining portions are open in a communication passage within the header pipe. The heat-sink device may further have a first and second header pipe, and the heat-pipe body may be disposed vertical such that the flow passages run in a horizontal direction and are open in a first and second communication passages within the first and second header pipes.
