Abstract:
1. A heating, ventilating, and air conditioning assembly for heating, venting, and cooling a passenger compartment of a vehicle, said assembly comprising; a hollow housing having an inlet and at least one outlet for directing a flow of air into the passenger compartment; a first heat exchanger disposed within said housing downstream of said inlet and upstream from said outlet with said first heat exchanger being an evaporator core arranged and configured for intercepting substantially all of the air flowing into the passenger compartment; and a second heat exchanger disposed within said housing between said first heat exchanger and said outlet with said second heat exchanger being a heater core having an upstream surface generally facing said first heat exchanger and a downstream surface generally facing said outlet; said second heat exchanger including a first portion having a plurality of fins spaced from each other and a second portion having a plurality of fins spaced from each other wherein said plurality of fins of each of said first and second portions of said heater core are spaced apart from each other in a non-uniform manner, with said first and second portions each having central and peripheral regions with said fins extending continuously across said regions with said plurality of fins of said first portion having a higher concentration in said central region and said central regions abutting each other such that said fins of said second heat exchanger extend continuously between said opposing peripheral regions of said portions, said second portion being angled relative to said first portion such that said upstream surface of said first portion at least partially faces said upstream surface of said second portion to define an angled second heat exchanger facing said first heat exchanger wherein air flowing over said upstream surfaces is evenly distributed across said plurality of fins of both of said first and second portions, thereby increasing the effectiveness of said second heat exchanger.
