Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2023/152789
Kind Code:
A1
Abstract:
This heat exchanger comprises: a first divider for dividing refrigerant into a plurality of flows; one or more second dividers for furthermore dividing one of the plurality of flows of refrigerant divided by the first divider into a plurality of flows; and a plurality of heat transfer pipes arranged in the center-of-gravity direction, the plurality of heat transfer pipes constituting three or more refrigerant paths. The second dividers each have a connection part that is part of the three or more refrigerant paths and that connects together the heat transfer pipes constituting the plurality of refrigerant paths, the connection parts each having a plurality of refrigerant flow channels formed in the interior thereof, and an opening connected to the first divider being formed in each of the connection parts. One heat transfer pipe among the plurality of heat transfer pipes is connected to the first divider via the one or more second dividers and constitutes one or more groups of a plurality of first refrigerant paths into which the plurality of flows of refrigerant divided by any of the one or more second dividers flow. The remaining heat transfer pipes among the plurality of heat transfer pipes are connected to the first divider directly without interposition of the one or more second dividers and constitute one or more second refrigerant paths into which one of the plurality of flows of refrigerant divided by the first divider directly flows.
