G0601-3-1 Development of the cold heat in winter storage system using heat pipes

Abstract

The heat pipe can transfer the heat only from the lower position to the upper position in the gravitational field. The natural cold heat storage system is developed by making use of the characteristics of the heat pipes. The experiments have been conducted in the field, paying attention to the effect of the amount of the working fluid in the heat pipe on the figure of the manufactured ice surrounding the heat pipe. It is cleared that the heat pipe can manufacture the ice cylindrically, but excessive working fluid obstructs the ice generation.
