Abstract

The SEMOS-HP (Self-Exiting Mode Oscillating-Flow Heat Pipe) consists of a closed capillary loop meandering between heated and cooled parts. The closed loop is vacuumed and then it is charged with an operating liquid up to a volume fraction. When the temperature difference between the heated and cooled parts is increased beyond a critical value, the operating fluids lining up as liquid columns and vapor plugs along the closed loop starts to oscillate and circulate in the loop. In the present paper, the effects of some system parameters on the heat transport characteristics of the SEMOS-HP were experimentally investigated and the following results were obtained. A vertical SEMOS-HP with R 141 b and 0.8mm in inner diameter can transport sufficient amount of heat. The SEMOS-HP can operate at inclination angles (=0 for the horizontal plain) down to 3 degree. The effective thermal conductivity of SEMOS-HPs is not sensitive to wall material and initial vacuum of the tube. The contribution of sensible heat transport to the total heat transport is not neglibible. Finally, a stop valve effect of liquid columns is presented as one of the mechanisms driving the pulsating flow of the operating fluids.
