DESIGN AND STUDY OF HEAT PIPE WATER HEATERS IN 2t/h BOILERS

This paper introduces characters of structure and heat transfer of the heat pipe water heater newly designed and made by Institute of Energy Resources, and compares with the traditional water heater in some main technical parameters.The heat pipe water heater gives a higher efficiency heat exchanger,and has many advantages over traditional heat exchangers. The article expresses a postulate about the heat transfer model of heat pipes and simplifies the heat transfer calculations in the design of the heat pipe water heater,and also lists main calculation steps and equations.Combined with the design of the heat pipe water heater, the paper puts discussion forward about some main questions which deal with the design of heat pipe water heaters, such as the optimum length ratio of evaporator to condenser, external guestions of heat pipe water heaters, and so on.
