<p>PROBLEM TO BE SOLVED: To provide an evaporator having a cold storage function while suppressing the increase in weight.SOLUTION: An evaporator having a cold storage function is equipped with a plurality of refrigerant flow pipes 12 having a longitudinal direction arranged vertically and juxtaposed at a mutual spacing. Of all gaps 14A and 14B formed between the adjoining refrigerant flow pipes 12, partial gaps 14A are arranged with condensed water storage parts 15 whereas the remaining gaps 14B are arranged with heat transfer fins 16. These heat transfer fins 16 are positioned in the gaps 14B on the two sides of the gaps 14A, in which the condensed water storage part 15 is arranged. The condensed water storage part 15 has a corrugate fin shape, which is composed of vertically extending wave apexes 15a, vertically extending wave bottoms 15b, and connection parts 15c connecting the wave apexes 15a and the wave bottoms 15b. The condensed water storage part 15 is equipped with a ventilation part formed of a through hole 18. The ventilation resistance of the gap 14A, in which the condensed water storage part 15 is arranged, is made higher than that of the gap 14B, in which the heat transfer fins 16 are arranged.</p> |
