Early in the design process of a copper/brass automotive heat exchanger, such as a radiator or heater core it is desirable to determine the heat transfer performance of the proposed design. Straight forward computer aided design can be used in the form of a BASIC computer program that can be run on a personal computer. By developing such a program an insight can be gained into the mechanisms at work within the heat exchanger core. This paper is a mathematical heat transfer study of a typical copper/brass automotive heat exchanger. The heat transfer mechanisms which are involved in this crossflow type heat exchanger are broken down into their discreet paths. The paths to be studied are the coolant to the tube convective heat transfer, the fin to tube interface, and the fin to air convective heat transfer.
