Claims

[Scope of utility model registration request]

An evaporation chamber in which a pair of dish-shaped tube sheets are joined to face each other to allow refrigerant to flow therein; an inlet header section communicating with one end of the evaporation chamber and an outlet header section communicating with the other end; A laminated structure in which a plurality of heat exchange units with openings connected in parallel are connected in parallel so that each header portion communicates with each other, and air passages for flowing air between adjacent heat exchange units are formed in parallel. In the type evaporator, scattered protrusions are formed on the inner wall surface of the dish-shaped tube plate constituting the evaporation chamber, and the density of the protrusions is coarse on the windward side of the air flow and dense on the leeward side. A stacked evaporator characterized by being formed as follows.
