The subject invention includes a heating, ventilating, and air conditioning (HVAC) assembly having a housing with an inlet and at least one outlet for directing a flow of air into a passenger compartment. An evaporator core is disposed within the housing downstream of the inlet and upstream from the outlet. A heater core is disposed within the housing between the evaporator core and the outlet with the heater core having an upstream surface generally facing the evaporator core and a downstream surface generally facing the outlet. The heater core includes a first portion and a second portion being angled relative to the first portion such that the upstream surface of the first portion at least partially faces the upstream surface of the second portion to define an angled heater core facing the evaporator core wherein air flowing over the upstream surfaces is evenly distributed across both of the first and second portions, thereby increasing the effectiveness of the heater core.

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. 2. An assembly as set forth in claim 1 wherein said first portion is angled relative to said second portion by more than 90 degrees.3. An assembly as set forth in claim 2 wherein said first portion is angled relative to said second portion by 140 degrees.4. An assembly as set forth in claim 3 wherein said downstream surface of said first portion is angled relative to said downstream portion of said second portion by 140 degrees.5. An assembly as set forth in claim 4 wherein each of said first and second portions have a substantially flat rectangular configuration.6. An assembly as set forth in claim 1 wherein said plurality of fins of said second portion of said heater core are spaced apart from each other in a uniform manner.7. An assembly as set forth in claim 1 wherein said housing further includes an upper quadrant and a lower quadrant with said evaporator core disposed within both of said quadrants and said heater core disposed within said lower quadrant.8. An assembly as set forth in claim 7 further including at least one flow valve disposed within said housing for controlling the flow of air between said upper and lower quadrants.9. An assembly as set forth in claim 7 wherein said housing further includes three outlets for distributing the flow of air throughout the passenger compartment.
