Circular Finned Radiator

The Heat Exchangers or Radiators used in automobiles /IC Engines mainly in cars and trucks are either rectangular or square in shape, but the air blown/sucked by means of the fan is in circular in area, developing low velocity zones in the corners-hence it is proposed to eliminate corners and develop circular radiators so as to maximize the heat transfer rate . The object of work is to have a circular radiator which is compact-made with minimum material-more efficient-that will work with minimum power consumption of fan and maximum either utilization of air flow.
