Many studies have been made on the heat transfer of pins in connection with pin-fin heat-exchangers as the heat conduction problems but hardly measured their heat transfer rate. In this point of view, as the first step, the authors have measured the heat transfer rate between a single circular pin which is fixed on a plate in parallel air flow. The pin, having the diameter D=12 mm and the length L=12 mm〜36 mm, is fixed on the plate 615 mm in length and 110 mm in breadth ; the position of the pin is varied five different distances from the entrance edge of the plate. The plate and the pin are separately heated ellectrically and the heat loss from the pin is determined. The results of these experiments have been expressed by the experimental formula in the range of Reynolds number R_<e(D)>=2×10^3〜2×10^4,and from which the effectiveness of a pin-fin surface has been calculated
