上記1)〜11)の蓄冷機能付きエバポレータによれば、蓄冷材容器の容器本体部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の帯状部からなり、かつ蓄冷材容器の上下方向の長さの７０％以上の長さおよび一定の幅を有する連続した直線状の垂直帯状ろう付部が設けられており、蓄冷材封入部が、両垂直帯状ろう付部間の通風方向の直線距離と同一の幅および風下側垂直帯状ろう付部の上下方向の長さ以上の高さを有する略縦長方形状の主封入部を備え、当該主封入部の風下側縁部および風上側縁部が垂直直線状であり、蓄冷材封入部の主封入部内の通風方向の寸法が、熱交換コア部の通風方向の寸法の８５％以上となっているので、蓄冷材封入部の伝熱部内の通風方向の幅を比較的大きくするとともに、蓄冷材封入部内に封入しうる蓄冷材の量を比較的多くすることが可能になり、蓄冷材に冷熱を蓄える蓄冷効果が向上する。さらに、蓄冷材容器が配置された間隙の通風方向下流端部において、冷媒流通管の風下側端部が、前記主封入部の風下側端部よりも風下側でかつ蓄冷材容器の風下側垂直帯状ろう付部の風下側端部よりも風上側に位置し、前記間隙の通風方向上流端部において、冷媒流通管の風上側端部と蓄冷材容器の風上側垂直帯状ろう付部の風上側端部とが通風方向の同一位置にあるので、蓄冷材封入部の主封入部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％以上とした上で、熱交換コア部の通風方向の幅の著しい増大を防止することが可能になり、蓄冷機能付きエバポレータの大型化を抑制することができる。
According to the evaporator with a cool storage function of the above 1) to 11), the cool storage material is composed of the strip-shaped portions of both container constituent plates brazed to the leeward side portion and the windward side portion of the container main body portion of the cool storage material container, and A continuous linear vertical belt-like brazing part having a length of 70% or more of the vertical length of the container and a certain width is provided, and the regenerator material enclosing part is between the vertical belt-like brazing parts A main enclosure having a substantially vertical rectangular shape having a width equal to the linear distance in the ventilation direction and a height equal to or greater than the vertical length of the leeward vertical belt-like brazing part, and the leeward side edge of the main enclosure The windward side edge is a vertical straight line, and the dimension in the ventilation direction in the main enclosure of the regenerator enclosure is 85% or more of the dimension in the ventilation direction of the heat exchange core, so the regenerator enclosure While the width of the ventilation direction in the heat transfer part is relatively large, the inside of the cool storage material enclosure It is possible to relatively increase the amount of cold accumulating material can be sealed, thereby improving the cold accumulating effect of storing cold energy in the cold accumulating material. Further, at the downstream end portion in the ventilation direction of the gap where the cool storage material container is arranged, the leeward side end portion of the refrigerant circulation pipe is leeward side of the leeward side end portion of the main enclosure and is perpendicular to the leeward side of the cool storage material container. Located on the windward side of the leeward side end of the belt-like brazing part, at the upstream end of the gap in the ventilation direction, the windward side of the windward side of the refrigerant flow pipe and the windward side of the cold storage material container Since the end portion is at the same position in the ventilation direction, the size of the cooling storage material enclosure in the main enclosure is set to 85% or more of the dimension in the ventilation direction of the heat exchange core, and then the heat exchange core Thus, it is possible to prevent a significant increase in the width in the ventilation direction, and it is possible to suppress an increase in the size of the evaporator with a cold storage function.
この実施形態のエバポレータ(1)の場合、冷媒は、冷媒入口(7)を通ってエバポレータ(1)の風下側上ヘッダ部(5)内に入り、全冷媒流通管(12)を通って風上側上ヘッダ部(6)の冷媒出口(8)から流出する。
In the case of the evaporator (1) of this embodiment, the refrigerant passes through the refrigerant inlet (7) and enters the leeward upper header portion (5) of the evaporator (1) and passes through the entire refrigerant circulation pipe (12). It flows out from the refrigerant outlet (8) of the upper upper header section (6).
蓄冷材容器(15)の蓄冷材封入部(25)は、両垂直帯状ろう付部(26)(27)間の通風方向の直線距離と同一の幅および風下側垂直帯状ろう付部(26)の上下方向の長さ以上の高さを有する略縦長方形状の主封入部(30)を備えている。ここでは、主封入部(30)の高さは、風下側の一部分を除いて、蓄冷材容器(15)の全高から上下両水平帯状ろう付部(28)(29)の幅を減じた寸法となっている。蓄冷材封入部(25)の主封入部(30)の風下側縁部および風上側縁部は上下方向にのびる垂直直線状であり、主封入部(30)内の通風方向の幅W1は、熱交換コア部(4)の通風方向の全幅Ｗの８５％以上となっている。
The cold storage material enclosing portion (25) of the cold storage material container (15) has the same width as the straight distance in the ventilation direction between the vertical belt brazing portions (26) and (27) and the leeward vertical belt brazing portion (26). A main enclosing portion (30) having a substantially vertical rectangular shape having a height equal to or greater than the vertical length of the main enclosure (30). Here, the height of the main enclosure (30) is the dimension obtained by subtracting the width of the upper and lower horizontal strip brazing parts (28) (29) from the total height of the cool storage material container (15) except for a part on the leeward side. It has become. The leeward edge and the windward edge of the main enclosure (30) of the cool storage material enclosure (25) are vertically straight, and the width W1 in the ventilation direction in the main enclosure (30) is: It is 85% or more of the total width W in the ventilation direction of the heat exchange core part (4).
