Summary

A TWO-PHASE CLOSED-LOOP THERMOSIPHON IS LARGER THAN A NON-LOOP THERMOSIPHON, BECAUSE FLOODING PHENOMENON OCCURRING IN THE NON-LOOP SYSTEM DOES NOT OCCUR IN THE FORMER ONE. ANOTHER MERIT IS THAT THE EVAPORATOR AND CONDENSER CAN BE INSTALLED IN A COMPARATIVELY ARBITRARY POSITION. OVERALL HEAT RESISTANCES CONSIST OF 3 HEAT RESISTANCES: THOSE IN THE EVAPORATOR, CONDENSER AND THE TRANSPORT RESISTANCE IN THE INTERCONNECTING PIPE. THEREFORE, ONE SHOULD CONSIDER THESE HEAT RESISTANCES SEPARATELY. IN THE PRESENT STUDY, THE AUTHORS TOOK NOTE OF THE HEAT RESISTANCES OF THE EVAPORATOR AND THE CONDENSER. THE EFFECTS OF ROTATION ANGLE, HEAT FLUX, INSIDE TEMPERATURE (OR PRESSURE) ANDLIQUID CHARGE WERE INVESTIGATED.
