Claims (1)

[Scope of utility model registration request] Two plates 30 each having a substantially rectangular shape with a concave portion formed on the inner surface and a partition wall 32 extending halfway in the longitudinal direction from one end toward the other end formed on the inner surface at the center in the width direction are mutually connected. In a stacked evaporator in which a pair of core units 40 are formed by joining the inner surfaces facing each other, and a large number of the core units are stacked to form a U-shaped refrigerant passage in each core unit, each of the plates A large number of circular beads 39 are formed in the evaporator section 30 so as to protrude from the inner surface of the evaporator section, and one evaporator section is separated from the communication section 38 formed between the partition wall and the other end of the plate. A laminated type evaporator in which a band-shaped bead 14 is formed to protrude from the inner surface of the plate to guide the refrigerant flowing from one evaporator section to the other end corner of the plate.
