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.
