AbstractExperiments have been conducted to evaluate the thermal resistance between the heat pipe in an evacuated glass tube solar collector and a thermosiphon load via dry and wet couplings. The evacuated tube collector used was Philips type VTR 361 inclined at an angle of 25° to the horizontal facing south. Heat from the collector was transferred to water in a 1.4 litre container by (1 ) clamping the condenser of the heat pipe to a 28 mm diameter pipe through which water from the container flows by thermosiphoning, (2) by inserting the condenser of the heat pipe into a tube let into the bottom of the container. The average value of the thermal resistance was found to be 1.095 K/W in case (1) and 1.303 K/W in case (2). This was three times the resistance found by other workers who used forced convection in the ir experiments.
