This study was carried out to analyze the change of temperature and flow velocity at the exit side of the fan heater cover according to the change of the inlet temperature and the air flow rates for the production of the electric fan heater for aircraft. The analyses were performed with the commercial software, ANSYS 17.0. The CAD model was applied as follows; (1) Parts before the Coupler were eliminated. (2) The corner shape of the Heater was fixed so that it is rounded off. (3) The model was quartered. Its inside volume was meshed using a tetrahedral element. Though a couple of layer element should be meshed to express the boundary layer and to enhance the analytical accuracy, there is no layer mesh on the wall. In the analysis, the temperature increment was less than 274 K. Therefore, the most crucial reason about that is that the length of heater is too short to transfer heat energy to the air. Hence, it is strongly recommended that the length of the heater elongates or its specific surface area increases.
