Abstract
The present invention relates to an outdoor heat exchanger, and more particularly, to a down flow type outdoor heat exchanger having channels of at least three paths in a heat pump system for vehicles, in which a flux distribution means protruded in a height direction is further formed in a lower tank in which the channel is changed from an upward direction to a downward direction or from a downward direction to an upward direction to block some area of a lower portion thereof so as to prevent a refrigerant from being non-uniformly distributed while a flux is concentrated toward a rear side of the channel due to a fluid inertia in an area in which the flow path is changed, thereby delaying frosting upon heating.
