STACKING-TYPE HEADER, HEAT EXCHANGER, AND AIR-CONDITIONING APPARATUS

摘要

A stacking-type header according to the present invention includes: a first plate-shaped unit having a plurality of first outlet flow passages formed therein; and a second plate-shaped unit stacked on the first plate-shaped unit, the second plate-shaped unit having a distribution flow passage formed therein, the distribution flow passage being configured to distribute refrigerant, which passes through a first inlet flow passage to flow into the second plate-shaped unit, to the plurality of first outlet flow passages to cause the refrigerant to flow out from the second plate-shaped unit, in which the distribution flow passage includes a branching flow passage including a straight-line part perpendicular to a gravity direction, and in which the refrigerant flows into the branching flow passage through a part between both ends of the straight-line part, passes through both the ends, and flows out from the branching flow passage through a plurality of end portions.

1. A stacking-type header, comprising:
a first plate-shaped unit having a plurality of first outlet flow passages formed therein; and a second plate-shaped unit being mounted on the first plate-shaped unit and having a first inlet flow passage formed therein and a distribution flow passage formed therein, the distribution flow passage being configured to distribute refrigerant, which passes through the first inlet flow passage to flow into the second plate-shaped unit, to the plurality of first outlet flow passages to cause the refrigerant to flow out from the second plate-shaped unit, wherein the distribution flow passage comprises a branching flow passage including a straight-line part extending in a direction perpendicular to a gravity direction, and wherein the branching flow passage is configured to allow the refrigerant to flow thereinto through a part between both ends of the straight-line part, pass through both the ends, and flow out from the branching flow passage.
