Claims

[Scope of utility model registration request]

The straight pipe parts 2a of the flat pipe 2 having the refrigerant passages 4 are arranged in parallel with each other with a predetermined gap 5, and between each straight pipe part 2a,
A corrugated fin 3 consisting of parallel flat portions 3a and bent portions 3b between these flat portions 3a is interposed, and wind A is perpendicular to the refrigerant passage 4 by forced air blowing.
In the evaporator through which air flows, a partition wall 11 is provided inside the air intake side portion 8 of the flat tube 2 in the length direction of the flat tube 2, and a partition wall 11 is provided in the length direction of the flat tube 2 to separate the air intake side portion 8 and the air volume side portion 10 of the flat tube 2. A partition wall 12 made of a metal plate with a corrugated cross section is fixed inside the intermediate portion 9 between the two, thereby forming a large number of refrigerant passages 4.
A large number of communication portions 13 are formed to communicate with adjacent refrigerant passages 4, and condensed water discharge recesses 14, 15 are formed on the outer surface of the intermediate portion 9 of the flat tube 2 and the outer surface of the headwind outlet side portion 10. Each evaporator is provided with condensation water discharge notches 17 and 18 provided in the length direction of the flat tube 2, and at locations facing the condensation water discharge concave portions 14 and 15 of the bent portion 3b of the corrugated fin 3. vessel.
