Abstract

Experimental research has been carried out to investigate the thermal performance of a water-to-DI water heat-pipe heat exchanger. DI Water has been used as a working fluid in the heat pipe. The analysis is based on the effectiveness (ϵ)-"NTU" approach to determine the thermal performance of heat exchanger. Many factors influences the thermal performance of heat-pipe heat exchangers such as temperature of water in the inlet of evaporator section, mass flow rate of water and inclination angle of the heat exchanger. The mass flow rate of evaporator section has been varied from 20 lph to 100 lph, while the condenser section flow rate has been altered in the ratio of 1:1, 1:1.5, 1:2, 1:2.5 and 1:3 as that of evaporator section. Many experiments were conducted under different operating conditions by varying the inclination angle of heat pipe from 0 to 60 in order to investigate their effect on the thermal performance of a heat-pipe heat exchanger. In this study, the effect of mass flow rate of water to the evaporator section, mass flow rate of water to the condenser section and inlet temperature of water to the evaporator section were analyzed. The effect of gravity assistance to the condenser section with respect to the effectiveness also determined. It was found that, for all operating conditions the effectiveness of GAHPHX has increased with increase in mass flow rate of water to the evaporator section and maximum value at 80 lph. The optimum effectiveness of GAHPHX has been obtained when Ch = 2 Cc for all operating conditions.
