HEAT EXCHANGER

PROBLEM TO BE SOLVED: To provide a heat exchanger capable of more uniformly distributing temperature of blowout air.SOLUTION: A heat exchanger includes: a leeward side inflow tank part 182a which flows into a leeward side first tube group 181A coolant before heat exchange by a windward side heat exchange part 17a and a leeward side heat exchange part 18a; a leeward side intermediate tank part 183 which flows the coolant heat exchanged in the leeward side first tube group 181A into a leeward side second tube group 181B; a windward side inflow tank part 172b which flows into the windward side first tube group 171A coolant before heat exchange at the windward side heat exchange part 17a and the leeward side heat exchange part 18a; and a windward side intermediate tank part 173 which flows into a windward side second tube group 171B coolant heat exchanged in the windward side first tube group 171A. When viewed from an air flowing direction A1 with respect to the windward side heat exchange part 17a and the leeward side heat exchange part 18a, the windward side first tube group 171A is polymerized with the leeward side second tube group 181B.SELECTED DRAWING: Figure 7 【課題】吹出空気の温度分布を一層均一化できる熱交換器を提供する。【解決手段】風上側熱交換部１７ａおよび風下側熱交換部１８ａで熱交換される前の冷媒を風下側第１チューブ群１８１Ａに流入させる風下側流入タンク部１８２ａと、風下側第１チューブ群１８１Ａで熱交換された冷媒を風下側第２チューブ群１８１Ｂに流入させる風下側中間タンク部１８３と、風上側熱交換部１７ａおよび風下側熱交換部１８ａで熱交換される前の冷媒を風上側第１チューブ群１７１Ａに流入させる風上側流入タンク部１７２ｂと、風上側第１チューブ群１７１Ａで熱交換された冷媒を風上側第２チューブ群１７１Ｂに流入させる風上側中間タンク部１７３とを備え、風上側熱交換部１７ａおよび風下側熱交換部１８ａに対する空気流れ方向Ａ１から見たときに、風上側第１チューブ群１７１Ａは、風下側第２チューブ群１８１Ｂと重合している。【選択図】図７
