Abstract:
1. A heat exchanger comprising: a refrigerant inlet header; a refrigerant outlet header arranged side by side with the refrigerant inlet header in a front-rear direction at an upper end of the heat exchanger; and a refrigerant circulating passage which holds the two headers in communication therethrough, wherein the inlet header has a refrigerant inlet at one end thereof, the outlet header has a refrigerant outlet at one end thereof alongside the inlet, the refrigerant circulating passage has a plurality of heat exchange tubes which has a plurality of upper portions, respectively, the upper portions of the heat exchange tubes are connected to the inlet header and the outlet header, a refrigerant is flowable into the inlet header from the inlet and thereafter returnable to the outlet header through the circulating passage so as to be sent out from the heat exchanger through the outlet, the refrigerant inlet is provided in a closing member closing an opening of the inlet header at said end thereof, the closing member has a lower edge defining the inlet and provided with a guide slanting upward inwardly of the inlet header, and the guide is in the form of a segment of a sphere and has a projecting end face positioned on a slanting plane inclined with respect to a vertical inner surface of the closing member such that at least a portion of the refrigerant which passes through the inlet makes contact with the guide and is directed to flow obliquely upward along the guide and into the inlet header.
