Abstract

PURPOSE:To improve transmission of heat by forming recesses in a heat receiving section of a heat pipe. CONSTITUTION:Bubbles 4 produced at a lower portion of work fluid rise upward along the upper surface of the pipe wall. However, since recesses B are formed in the pipe wall, the rising direction of the bubbles is changed by the recess B and carried toward the lower surface of the pipe wall. As the bubbles rise further upward, the above process is repeated. Since the bubbles are carried toward the lower surface of the pipe wall as described above, turbulence is produced in the work fluid, so that bubbles can be produced from the entire surface of the pipe wall. Thus, it is enabled to raise the efficiency of heat transfer irrespective of the setting angle of the heat pipe.
