Abstract:
In combination with a motor vehicle, the motor vehicle includinga frame,a prime mover mounted on the frame,a coolant, anda circulation system for moving the coolant adjacent the prime mover to absorb heat from the prime mover,the improvement comprising a radiator for receiving coolant from said circulation system and removing heat from the coolant, the radiator comprising(a) a first heat transfer section to receive coolant from the circulation system, said first section including at least one conduit for receiving coolant and a plurality of spaced apart fins contacting and extending outwardly from said conduit, said heat transfer section including a plurality of spaces each intermediate an adjacent pair of said fins, said fins including a first side and a second side and being shaped and dimensioned such that air flowing in said first side passes through said spaces, by said conduit and exits said spaces from said second side in turbulent flow; and,(b) a second heat transfer section in fluid communication with said first heat transfer section to receive coolant from said first heat transfer section, said second heat transfer section including at least one conduit for receiving coolant and a plurality of spaced apart fins contacting and extending outwardly from said conduit said second heat transfer section including a plurality of spaces each intermediate an adjacent pair of said fins in said second heat transfer section, said fins of said second heat transfer section including a first side spaced a selected distance apart from said second side of said fins of said first heat transfer section; said second section being spaced apart from said first section a distance in the range of three-quarters of an inch to six inches such that air exiting said spaces in said first heat transfer section and said second side of said first heat transfer section(c) flows toward and into said spaces in said second heat transfer section, and(d) assumes laminar flow prior to entering said spaces in said second heat transfer section.
