Abstract
A heat exchanger includes flat tubes, a header to which the flat tubes are connected, an inflow plate that separates a refrigerant inflow portion and a lower circulation portion, a vertical dividing plate that separates the lower circulation portion and an upper circulation portion, a lower dividing plate that divides the lower circulation portion into a lower ascent path on an internal side and a lower descent path of an external side, and an upper dividing plate that divides the upper circulation portion into an upper ascent path on a leeward side, and an upper descent path on a windward side, wherein the inflow plate includes an ejection hole on a leeward side and an internal side, and the vertical dividing plate includes a first passing port on a leeward side and an internal side, and a second passing port on a windward external side.
