The present heat exchangers/radiators are rectangular in shape. But the air blown by the fan is circular in area, developing low velocity zones, high temperature regions in the corners. Therefore temperature and velocity readings are taken in all the four corners at various locations. It is claimed that stagnation zones are created in the corners and hence may be eliminated and proposed that the circular radiators, if developed, will be optimum for improvement in efficiency. Experimentation has been carried out by considering temperature and velocity as variable, reveals that low velocity zones along with high temperature regions (low heat transfer zones) are developed as presumed in the corners. The proposed design reduces/saves the material by 24%; cost saving on mass scale production will be about 20% once the dies are manufactured.
