Use of heat energy would heat transfer process is extremely important in engineering because of the need to involve the use of heat in the production of a variety of mechanical energy. Convection is the movement of one of the air force, using a heat transfer, which is important in engineering and the life of man, such as mechanical. Air conditioning, which rely on heat transfer process by treating her. Which this study mission to establish the objective study of the heat transfer coefficient for a test series with convection fans. To force the air through the air through the bars of iron, heating (Heater), intended to study the behavior of air forced convection. Analysis for the variable coefficient convection and devoid of these dimensions and can be used to calculate the values to predict the ability of heat transfer. It was found that.
