[0006] Therefore, depending on the storage state, the lower end part of the bent part of the heat exchanger on the downstream side in the airflow direction of the upper heat exchange part may be located on the downstream side than the lower heat exchange part. There is a possibility of scattering to the downstream side

Abstract
The invention provides a heat exchanger in which scattering of condensate from a bend portion to the downstream side in an air flow direction can be suppressed, an air conditioner and a method for manufacturing a heat exchanger. An indoor heat exchanger (10) comprises a lower fin (30), and an upper fin (40). The upper fin (40) has an angle in the longitudinal direction with respect to the vertical direction on the side of air flow (F) direction which is inclining at an angle larger than the angle of the lower fin (30), and arranged contiguously to the upper end portion of the lower fin (30). Further the upper fin (40) has a bend (R) curved in the vicinity of boundary portion with the upper end of the lower fin (30) on the downstream side in an air flow (F) direction.
Description
technical field [0001] The present invention relates to a heat exchanger, an air conditioner, and a method for manufacturing the heat exchanger. Background technique [0002] Conventionally, in an air conditioner accommodating a heat exchanger, in order to reduce the size of the device, a layout in which the heat exchanger is bent in multiple stages and accommodated in the device has been proposed. [0003] Here, for example, among the air conditioners described in Patent Document 1 shown below, there is proposed an air conditioner in which a heat exchanger is bent in multiple stages so as to surround a cross-flow fan. In this air conditioner, by studying the arrangement of the heat transfer tubes and fins through which the refrigerant flows, the portion where the direction of air flow and the direction of refrigerant flow are counter-current was increased to suppress a decrease in heat exchange efficiency. In addition, in this air conditioner, since the water wettability o...
