18 Jul 1988TL;DR: In this article, a CERDIP housing is provided with a heat pipe that passes through the closure seal lid whereby the heat pipe terminates within the housing cavity at the hot end thereof.
Abstract: A CERDIP housing is provided with a heat pipe that passes through the closure seal lid whereby the heat pipe terminates within the housing cavity at the hot end thereof. A quantity of working fluid, such as fluorinated octane, is contained within the package cavity. The heat pipe communicates with cooling fins that produce a cold end thereof. Heat from the semiconductor device inside the housing boils the working fluid and is cooled thereby. The fluid vapor passes along the heat pipe and is condensed at the cold end to be converted back to liquid. As a result the semiconductor device is in direct communication with the heat pipe working fluid.

TL;DR: A flat type heat pipe for mounting a heating power element, capable of forming an optionally shaped heat transferring path with high accuracy, which is of a thin type and to which fins are easily attached as mentioned in this paper.
Abstract: A flat type heat pipe for mounting a heating power element, which is capable of forming an optionally shaped heat transferring path with high accuracy, which is of a thin type and to which fins are easily attached. The flat type heat pipe includes at least two aluminum plates substantially in parallel with each other and brazed to each other so as to form a heat transferring path therebetween. The flat type heat pipe also includes an operating liquid which fills the heat transferring path. Because the heat transferring path 25 is formed by means of press molding, punching, laser beam machining, or cutting various shapes of heat transferring paths can be formed finely and with high accuracy. The flexible flat type heat pipe can be made thin, which allows for a variety of uses. Grooves and wicks can be disposed in the heat transferring path, thereby improving the heat conductivity. Because the surface is flat, the fins can be easily attached thereto, thereby a satisfactory radiation effect can be obtained.
