Summary

The purpose of the study is to develop the top heat mode thermosyphon, which makes it possible, for example, to accumulate directly summer solar energy in the underground soil for the winter season. In such a case, it can exclude the complex piping and mechanical pump to circulate the hot water absorbed the solar energy through the piping system buried in the soil layer. Several ideas on top heat thermosyphon had been proposed, but there were few reports of the definite experiments. The authors carried out an experimental study of the top heat mode thermosyphon, with a simple lifting pipe, which could draw the working liquid from the lower condenser to the upper evaporator section. The main components, such as evaporator, lifting pipe, liquid reservoir trap and vapour nozzle were improved in the experiment in order to obtain the optimum operating range.
