ABSTRACT:
A laminate-type evaporator is disclosed which is formed of a main heat exchanger, an auxiliary heat exchanger, and a connecting member integrally brazed, such that brazing performance between the auxiliary heat exchanger and the connecting member is enhanced and moisture does not remain between the auxiliary heat exchanger and the connecting member, while setting brazing temperature to a temperature which does not melt the main heat exchanger and also while shortening brazing time. Convexities are formed on a block joint, and a width of a brazed portion connecting these convexities and an end plate is made to be 5 mm or less. Additionally, a dimension of a clearance between the end plate and block joint is made to be 0.5 mm or more.
