Abstract

PURPOSE: To easily form grooves in a heat pipe without using any special tools, by rolling an elastic metal plate with grooves into a cylinder with grooves in the inner surface thereof, and inserting the resulting cylinder into a heat pipe.
CONSTITUTION: A grooves plate 10 is prepared by forming narrow grooves in one surface of a flat plate. The grooved plate 10 is cut to a suitalbe size and then rolled with the grooves inside. The grooved plate 10 thus rolled is inserted into a heat pipe 1. Owing to the unrolling elastic force of the inserted grooved plate 10, it is closely fitted in the pipe 1 to be fixed therein. Thus, various types of heat pipes with grooves can be produced easily in required quantities without using any special tools.
