PURPOSE: To make the speed of the flow of steam, which is the flow of blocks of bubbles, quicker than the speed of the flow of liquid, which is the flow of the blocks of liquid, and divide the flow of the steam and liquid so as to be different.
CONSTITUTION: In a cooling device, in which a heat receiving section 1 is connected to a heat dissipating section 5 through a heat pipe so as to form a loop, the heat pipe between the outlet port of the heat receiving section 1 and the inlet port of the heat dissipating section 5 is constituted of a spiral tube 3-4, whose inner wall is provided with a spiral groove. The liquid flows through the spiral groove on the inner wall of the spiral tube while the steam flows through the central part of the spiral tube. According to this method, the flow of the steam arrives at the heat dissipating section 5 sooner than the flow of liquid and, therefore, cooling efficiency is improved.
