| Abstract: | This paper analyses theoretically the effects of fm height, fin thickness, tube diameter,fin spacing and bathe height of the radiator in forms of tube bundles with belieal fins onits convective heat transfer. Bed on experimed and the formulas of free convective heattransfer of vertical parallel plates and bare duct, the paper introduces a sendtheoreticalmethod to calculate the heat transfer of the radiator and gives the optimal structureparameters. |
