HEAT EXCHANGER FIN CONTAINING NOTCHES

A heat exchanger fin capable of increasing convective heat transfer by reducing internal conduction along an undesirable direction within the heat exchanger fin itself is disclosed. More specifically, the current invention reduces conduction within the heat exchanger fin along an undesirable direction along the direction of fluid flow because such conduction decreases the performance of the heat exchanger fin. A heat exchanger fin in accordance with the present invention utilizes a plurality of notches within the heat exchanger fin that is perpendicular to the direction of fluid flow to increase the resistance of conduction within the heat exchanger fin itself. By increasing the resistance of conduction in an undesired direction, the heat exchanger fin is capable of more uniform temperature to along the entire surface area to facilitate increase convective heat transfer in the desired direction.
