Abstract
A heat exchanger for use in warming the engine and passenger compartment of a vehicle during cold weather comprises a fluid retaining main body member having a first end, a second end, a main longitudinal axis extending from the first end to the second end, and a substantially hollow interior. An inlet and an outlet are mounted on the main body member in fluid communication with the substantially hollow interior adjacent the first end and second end respectively. An exhaust flow passageway having an inlet end and an outlet end in fluid communication one with the other, for in-line connection with a vehicle exhaust system, is mounted in the main body member in throughpassing relation such that the hollow interior of the main body member substantially surrounds the exhaust flow passageway in heat transfer relation. In use, a heat transfer fluid ingresses the main body member through the inlet, flows from the first end to the second end of the main body portion through the hollow interior whereat heat from the exhaust flow passageway is absorbed, and egresses through the outlet. The heat exchanger is used in a heat recovery system such that the inlet is connected in fluid communication to a coolant outlet of the engine so as to receive liquid coolant therefrom, and the outlet is connected in fluid communication to a coolant inlet of a heater within the vehicle, so as to supply heated liquid coolant to the heater, and ultimately back to the engine.
