Claims

[Scope of utility model registration request]

A corrugated fin 3 is interposed between each vertical straight pipe section 2a of a meandering heat exchange tube body 2 having a plurality of refrigerant passages 4, and wind A is forced to flow perpendicularly to the refrigerant passage 1. In the evaporator, a heat exchange tube body 2 is joined to a first metal plate 5 having a corrugated cross section and having parallel condensed water discharge grooves 7 open upwardly and laterally and open downwardly and laterally. Required number of condensation water drain grooves 8 extending in the length direction
The refrigerant passage 4 surrounded by the first metal plate 5 and the second metal plate 6 is formed in parallel in the heat exchange tube body 2, and has a meandering shape. A portion 9 without a condensed water discharge groove 7 is provided on the first metal plate 5 at the lower bent portion 2b of the heat exchange tube body 2, and a communication portion 10 for communicating the refrigerant passages 4 is provided inside this portion. evaporator.
