Abstract:
1. A heat exchanger comprising: a refrigerant inlet header and a refrigerant outlet header arranged side by side forwardly or rearwardly in a forward to rearward direction of the exchanger, and a refrigerant circulation passage for holding the inlet and outlet headers in communication with one another, the circulation passage being provided by a plurality of intermediate headers and a plurality of heat exchange tubes, the inlet header being opposed to one of the intermediate headers, the outlet header being opposed to another one of the intermediate headers, a group of heat exchange tubes arranged at a spacing laterally of the exchanger in at least one row between each of the opposed pairs of headers, the group of heat exchange tubes having opposite tube end portions joined to each opposed pair of headers, a refrigerant flowing into the inlet header being returnable to the outlet header through the circulation passage and flowable out of the outlet header, the outlet header having an interior divided by separating means into a plurality of spaces arranged in the direction of height, the heat exchange tubes joined to the outlet header being in communication with one of the spaces, a refrigerant outlet being provided in communication with another one of the spaces, the separating means having a plurality of spaced refrigerant passing holes formed laterally therein, each of the refrigerant passing holes being positioned between respective adjacent pairs of heat exchange tubes arranged longitudinally of the outlet header and included in the group of heat exchange tubes joined to the outlet header, and the distance between an end refrigerant passing hole to a respective end of the separating means is longer than the distance between said end refrigerant passing hole and an immediately adjacent refrigerant hole.
