ABSTRACT:
A curved heat exchanger for a vehicle has tubes generally sector shaped in cross section and arranged in an arcuate pattern to transmit heat exchanger fluid between laterally spaced tanks. One embodiment has discrete heat exchanger fluid sections respectively connected to a vehicle engine, torque converter transmission and between the air conditioner compressor and evaporator. The tubes are tilted to align air passages therebetween with the radial direction of air flow discharged from an interior fan so that there is improved fan-heat exchanger matching resulting in reduced separation of air from the surfaces of the heat exchanger tubes and turbulence in the air passages. The side walls of adjacent tubes are equally spaced from one another to receive standard width air centers therebetween. The tubes may have discrete inner and outer flow sections insulated from one another and respectively employed to conduct engine coolant and another heat exchanger fluid such as for the air conditioning system. This invention features air pressure drop through the core so that a low horse power motor drive can be effectively utilized to pump cooling air through the heat exchanger. In another embodiment of the invention, axial flow fans are mounted at the ends of the cylindrical heat exchanger.
