ABSTRACT:
A stack type evaporator has a compact structure and a high cooling ability. A plurality of flat and plate-like tubular elements 1, each having a pair of formed plates 7, are stacked together in the lateral direction. Each tubular element 1 has two or more passages 10 inside it, each extending along the longitudinal direction. A refrigerant flows through a forward passage 10 in the tubular elements 1, and shifts to a return passage 10 in the direction opposed to the air flow. A corrugate inner fin 11 is placed throughout the refrigerant passages 10. One of the formed plate pair 7 has short cylindrical tanks 12a projecting outward, while the other has short cylindrical tanks 12b projecting outward, but in the opposite direction. When stacking up the tubular elements 1, the tanks 12a are fit into the corresponding tanks 12b of the adjacent formed plate 7 of the next tubular element 1.
