Embodiment Construction

[0049] The first technical solution of the present disclosure provides an outdoor heat exchanger, wherein,

[0050] The outdoor heat exchanger has:

[0051] flat tubes having a cross-sectional shape elongated along a first direction are arranged to face each other in a second direction orthogonal to the first direction, and the outdoor air flows from the first direction between these flat tubes. one side in one direction flows toward the other side, and the flat tube has a refrigerant flowing therein; and

[0052] The corrugated fin is disposed between the adjacent flat tubes, and includes a plurality of plate portions arranged in a third direction perpendicular to the first direction and the second direction, and adjacent to all of the flat tubes. A plurality of folded parts of the above-mentioned flat tubes are selected to be joined together,

[0053] On each of the plurality of plate portions, a plurality of skylights inclined with respect to the first direction by being ...

Abstract

A corrugated fin (6) disposed between flat tubes (5) having a cross-sectional shape extending along a first direction includes a plurality of plate portions (6A) and a plurality of folded portions (6B). A plurality of skylights (7) inclined relative to the first direction by cutting are formed substantially continuously along the first direction at each plate portion (6A). In addition, each plate portion (6A) has an extension portion (60) protruding to the windward side in the first direction from a joint region (8) where the folded portion (6B) and the flat tube (5) are joined. Among the skylights (7), the most front row skylights (7a) on the windward side are all arranged in the extension part (60). Each plate portion (6A) has a front end flat portion (61) on the windward side of the front row sunroof (7a). The area of ​​the front end flat portion (61) exceeds half of the area of ​​the extension portion (60).

Description

technical field [0001] The present invention relates to an outdoor heat exchanger and a vehicle air conditioner using the same. Background technique [0002] Conventionally, for example, in a motor vehicle equipped with a gasoline engine, a heat pump is used for cooling, while waste heat from the engine is used for heating. In recent years, hybrid vehicles with less waste heat from the engine and electric vehicles that cannot use the waste heat from the engine have become popular. Accordingly, a vehicle air conditioner has been developed that not only uses a heat pump when the air is turned on, but also Heat pumps are also used when turning on the heat. [0003] For example, Patent Document 1 discloses an outdoor heat exchanger that is used in a heat pump type vehicle air conditioner and functions as an evaporator during heating operation. In this outdoor heat exchanger, such as Figure 17A and Figure 17B As shown, the flat tubes 110 are arranged to face each other so th...
