An internal heat exchanger unit for use in refrigerant circuits of automotive air conditioning systems. The internal heat exchanger includes a casing within which is located an accumulator, spaced thereapart so as to define a gap between the two components. Located within the gap is a coil-shaped fin tube. The fins of the fin tube include bend end portions at spaced apart locations about the fins, and the bent end portions defining an outer dimension of the fins that substantially corresponds to the gap width. |
