Outdoor unit and refrigeration cycle device

摘要

An outdoor unit includes an outdoor air heat exchanger formed of an air heat exchanger that includes multiple aligned fins and a heat transfer tube intersecting the fins at multiple positions and transferring heat of a refrigerant flowing in the tube and that exchanges heat between the refrigerant and air; and a blower fan forming a flow of the air flowing through the outdoor air heat exchanger. In the outdoor air heat exchanger, the heat transfer tube intersects the fins at intervals based on a flow rate of the air flowing into the outdoor air heat exchanger according to a positional relationship with the blower fan.

主权项

1. An outdoor unit comprising:
an outdoor air heat exchanger formed of an air heat exchanger that includes a plurality of aligned fins and a heat transfer tube allowing a refrigerant to flow therein and including a plurality of heat transfer tube segments, the heat transfer tube segments each being formed on the heat transfer tube as being bent and intersecting the fins at a plurality of positions and allowing a refrigerant to flow therein, the heat exchanging heat between the refrigerant and air; and a blower device forming a flow of the air flowing through the outdoor air heat exchanger, wherein, in the outdoor air heat exchanger, intervals between adjacent ones of the heat transfer tube segments being formed on the heat transfer tube as being bent are set to increase toward a region in which a volume of air flowing into the outdoor heat exchanger is large from a region in which the volume of air flowing into the outdoor heat exchanger is small.
