Claims

[Scope of utility model registration request]

A tube plate 2 having a heat exchange recess 4 formed on the inner surface of the central part of a substantially rectangular plate material, and tank recesses 5 and 6 formed at both ends of the heat exchange recess 4, each having an inner surface. In a stacked evaporator formed by facing tube units and a plurality of fins stacked alternately, a wall member 2 is provided on the inner surface of the tube plate 2 and partitions the tube unit into a plurality of channels 21a, 21b, and 21c in the longitudinal direction.
0, a supply hole 7 is formed in the tank recess corresponding to the flow path, a communication groove 22 is formed between the heat exchange recess and each of the tank recess, and a supply hole 7 is formed in the tank recess corresponding to the flow path. A refrigerant dispersion bead 13 is formed on the windward side, and the width of the flow path on the windward side, the inner diameter of the supply hole, and the width of the communication groove are set larger than on the leeward side, and the refrigerant dispersion bead 13 on the windward side A laminated evaporator characterized in that the density of the refrigerant No. 13 is set lower than that on the leeward side so that a large amount of refrigerant flows on the windward side.
