Abstract
Cross Flow type of heat exchanger seems likely to have superior characteristics designing a large heat transfer surface area per unit volume. In this study, new approached version of counter flow type of heat exchanger by using a 45° inclined plate fin arrangement and employing inserted plate between the fins raw are proposed in order to be up heat transfer enhancement of over all heat transfer coefficient. Four types of exchanger, i.e., conventional cross flow type with inserted plate (I), converted counter flow type with inserted plate (II) (III), and conventional marketing type (IV) are tested by experiment as a parameter of the magnitude of exchanged temperature difference and the mass flow rate. Obtained data are discussed as a relation of effectiveness and number of transfer rate, and exergy transfer. It is cleared that new proposed counter flow type (II) (III) have interesting heat exchanging characteristics.
