Claims

[Scope of utility model registration request]

(1) In a stacked evaporator in which tube elements forming refrigerant passages and fully gated fins are stacked in an alternating arrangement, and an upper tank and a lower tank are provided which communicate with the passage above and below, both upper and lower By providing a separating partition wall along the flow direction of the refrigerant and a meandering partition wall orthogonal thereto in the tank, a plurality of mutually separated and independent refrigerant circuits are provided, each of which allows the refrigerant to meander three or more times. A refrigerant circuit is formed in which the refrigerant passages of the tube element are divided into three or more passage groups, and the refrigerant numbers are made to flow in opposite directions between adjacent refrigerant circuits,
A plurality of refrigerant outlets and refrigerant inlets corresponding to the number of circuits are provided in the upper tank and the lower tank, respectively, in a sequentially opposing arrangement, and further, the refrigerant passage is located on the refrigerant inlet side and the same outlet side in each of the circuits. A stacked evaporator characterized in that the passage cross-sectional area of a group of passage sections located in the middle thereof is formed to be relatively small with respect to the cross-sectional area of the passages of the group.

(2) The stacked evaporator according to claim 1, wherein the passage area of each refrigerant passage group is changed depending on the number of tube elements belonging to the passage group.
