An experimental investigation was made on the total performance estimation between the heat transfer and pressure drop characteristics using several kinds of spacer configurations in a rectangular channel. Performance differences between several kinds of spacer configurations were determined by considering the estimation method on heat transfer and pressure drop and introducing the configuration factor on heat transfer and pressure drop. As the result, there was not very much change of local heat transfer coefficient distribution, but pressure drop decreased very much in the case of front edge side and both front and rear edge side cutting against the spacer configuration. We obtained heat transfer and pressure drop characteristics with the spacer configuration factor against several kinds of spacer configurations and estimated the total performance. Cylindrical-type (CD), front edge side cutting-type (RU,EU,HPU), and both front and rear edge side cutting-type (RB,EB) spacers gave more excellent performance than standard-type spacer (SD).
