Description
本発明に係る熱交換器は、管軸が上下方向に延び、水平方向に並んで配置された複数の伝熱管と、前記複数の伝熱管の上側端部同士を接続する上側ヘッダと、を備え、前記上側ヘッダは、内部を前記複数の伝熱管の前記上側端部が挿入されている挿入空間と前記挿入空間の上側に位置する上側空間とに仕切る仕切部材を備え、前記仕切部材は、前記挿入空間と前記上側空間との間を連通する連通孔を備え、前記連通孔は、前記管軸に沿った方向の視点において前記複数の伝熱管の間に位置し、当該連通孔を通過して前記挿入空間に流入する冷媒の流速を増加させるものである。 The heat exchanger according to the present invention includes a plurality of heat transfer tubes having a tube axis extending in the vertical direction and arranged side by side in the horizontal direction, and an upper header for connecting the upper end portions of the plurality of heat transfer tubes. The upper header includes a partition member that partitions the inside into an insertion space into which the upper end of the plurality of heat transfer tubes is inserted and an upper space located above the insertion space, and the partition member is the partition member. A communication hole for communicating between the insertion space and the upper space is provided , and the communication hole is located between the plurality of heat transfer tubes in a viewpoint in a direction along the tube axis and passes through the communication hole. It increases the flow velocity of the refrigerant flowing into the insertion space .
