چکیده:

Waste heat recovery is very important, because not only it reduces the expenditure of heat generation, but also it is of high priority in environmental consideration, such as reduction in greenhouse gases. One of the devices is used in waste heat recovery is heat pipe heat exchanger. An experimental and theoretical research has been carried out to investigate heat performance of an air to water thermosyphon heat pipe heat exchanger according to ε-NTU method. The experiments were done according to the following procedure: cold water with 0.1kg/s flows through the condensation section and hot air in a closed cycle is blown to the evaporation section. A blower with varying frequency of current turns in the mass flow rate between 0.14-0.6 kg/s and temperature range of 125-225°C.the results of experiments show that as the ratio of ch/ccrises the amount of heat being transferred goes up. The efficiency of heat pipe heat exchanger remains constant as the temperature of hot stream goes up but the amount of heat transferred increases.
