| Abstract: | In this paper, two kinds of structural types of air-precooled heat exchangers , plate-fin and tube bundle, chosen and used for composite engines are suggested. A calculation followed all operating conditions is made to air-precooled heat exchangers, parameters of which are selected. Inherent charactristics of those kinds of heat exchangers,numerical results of their air duct drag characteristics,and influences of duct dimension and wall thickness on operating parameters of heat exchangers are shown clearly. Also some suggestions about future task are proposed. |
