Abstract
In order to achieve high heat transport performance, a new heat transport device with phase change using two parallel tubes has been developed. The device consisted of two different diameter parallel tubes, which connected an electrically heated evaporator and a water-cooled condenser. Experiments were conducted systematically using water as working fluid. Time-dependent temperatures as well as pressures at the evaporator and the condenser were continuously measured and recorded. The heat transport rate was obtained from the temperature rise and mass flow rate of cooling water in condenser. The present study disclosed that a simple two-different-diameter tube system connecting a heat source and a heat sink achieved re-circulating flow and it gave an extremely high heat transport rate. It was also found in the present study that the orientation of the device had appreciable influence on the performance.
