Experiments have been carried out on the free convection heat transfer from horizontal cylinders in array of staggered arrangements. Average heat transfer coefficients of individual cylinders and whole cylinder arrays were measured in order to clarify dependabilities of those coefficients upon the geometric figures including spacing and off-set distance between two cylinder lines,. Visualization of flow fields around the array has also been tried to explain the heat transfer behavior of cylinders in array. The experiments showed that there exist some optimum values of cylinder spacings and the off-set distances to increase the heat transfer coefficients and that the promoting effect in heat transfer can be expected especially when the array is set between parallel walls.
