ABSTRACT:
A refrigerant evaporator has a first heat exchange portion with an uninterrupted surface formed from sheets of conductive material joined together to form passages therebetween. A second heat exchange portion is connected to and adjacent the first portion. The second portion is formed from hollow, serpentine tubes with spine fins. Condensed refrigerant passes through the first portion, which accummulates frost and ice, and then through the second portion. The first portion also includes a labyrinth of passages that define an accumulator for refrigerant that has passed through the second heat exchange portion.
