PROBLEM TO BE SOLVED: To provide an evaporator with a cold storage function capable of improving cold storage effect and restricting an entire large-sized formation.SOLUTION: Vertical belt-like brazing segments 26 composed of belt-like portions 23, 24 of both container composing plates 21, 22 brazed to each other and having a specified length and a specified width are disposed at a downstream side and an upstream side of a container main body part 18 of a cold storage container 15 arranged in a clearance between adjoining refrigerant flow pipes 12 of an evaporator with a cold storage function. Downstream and upstream edges of a main feeding part 30 of a cold storage feeding part 25 of the cold storage container 15 are formed as vertical straight lines, and a size in air feeding direction in the main feeding part 30 is more than 85% of a size of a heat exchanging core part in the air feeding direction. At the downstream end of the air feeding direction at a clearance 14A where the cold storage container 15, the downstream side end part of each of the refrigerant flow pipes 12 is placed at a more downstream side than the downstream side end part of the main feeding part 30 and positioned at more upstream side than the downstream end of the downstream side vertical belt-like brazing segment 26 of the cold storage container 15.
【課題】蓄冷効果を向上しうるとともに全体の大型化を抑制しうる蓄冷機能付きエバポレータを提供する。【解決手段】蓄冷機能付きエバポレータの隣り合う冷媒流通管12どうしの間の間隙に配置された蓄冷材容器15の容器本体部18の風下側部分および風上側部分に、互いにろう付された両容器構成板21,22の帯状部23,24からなり、かつ一定の長さおよび一定の幅を有する垂直帯状ろう付部26を設ける。蓄冷材容器15の蓄冷材封入部25の主封入部30の風下側および風上側の縁部を垂直直線状とし、主封入部30内の通風方向の寸法を熱交換コア部の通風方向の寸法の85%以上とする。蓄冷材容器15が配置された間隙14Aの通風方向下流端部において、冷媒流通管12の風下側端部が、主封入部30の風下側端部よりも風下側でかつ蓄冷材容器15の風下側垂直帯状ろう付部26の風下側端部よりも風上側に位置する。【選択図】図4
