Abstract

In recent years the fan heater used for industry and residence has become smaller, lighter, and more silent as the result of improvement. However there are problems that the fan heater size is still very large, and the noise is very high due to air pressure loss of heat exchangers. Therefore we have been developing the centrifugal type fan with the function as heat exchanger. The features of this new type fan heater are that the fan heater size is very small and silent because the fan and the heat exchanger are in one body. This paper described the thermal flow characteristics that relationship exists between internal flow and local heat transfer coefficient, of the centrifugal fan with the function as heat exchanger that has 12 blades. The heat transfer characteristic was clarified by measuring heat flux and blade's surface temperature. Internal flow was clarified by numerical simulations using Front Flow／Blue.
