A testing system for thermal properties of solar gravity heat-pipes

This paper proposed a new design of a multifunction system for thermal properties testing of solar gravity heat-pipes. For the first time, all the experiment of solar gravity heat-pipe starting temperature, heat transfer ability, aging test and safety performance are done in a set of device in accordance with the requirements of “ISO/DIS-1 22975-2”. The starting temperature, isothermal performance and heat flow of solar gravity heat-pipes can be obtained by using the device. The device is based on enough experiment. The paper expounds the design idea, implementation method of the design basis and the use of experimental device. The experimental data are collected by PC control with the program written by LABVIEW. The experiment results show that the design is of simple operating and can meet the requirements of testing.
