Abstract: To store the natural coldness resource conveniently and quickly without noises and energy consumption, an experimental equipment of the heat transferring in a set of heat pipes, storing coldness via natural coldness resource, was designed on the basis of heat pipe technology. A one-dimensional heat transfer model on the process of ice making in single-pipe was established and verified by experiment results as follows: the radius of ice block was the power function of time of ice making, the analytic solution of the one-dimensional heat transfer model could be used to predict reliably the natural results, and the distance of a set of heat pipes, and they could be designed by the model also. The research offers effective theoretical basis for the design of the spacing interval of heat pipes and also predicting of the ice amount produced.
