Problems solved by technology

[0007] 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

Embodiment Construction

[0083] Hereinafter, embodiments of the air conditioner according to the present invention will be described with reference to the drawings.

[0084]

[0085] An air conditioner 100 according to one embodiment of the present invention includes an indoor unit 1 installed on a wall surface indoors and an outdoor unit 2 installed outdoors.

[0086] Heat exchangers are housed in the indoor unit 1 and the outdoor unit 2 respectively, and the respective heat exchangers are connected by refrigerant piping to constitute a refrigerant circuit.

[0087]

[0088] figure 1 The structure of the refrigerant circuit of the air-conditioning apparatus 100 is shown in .

[0089] The refrigerant circuit is mainly composed of an indoor heat exchanger 10 , an accumulator 21 , a compressor 22 , a four-way switching valve 23 , an outdoor heat exchanger 20 and an expansion valve 24 .

[0090] Heat exchange is performed between the indoor heat exchanger 10 provided in the indoor unit 1 and the ai...

Abstract

The present invention provides a heat exchanger, an air conditioner, and a method for manufacturing the heat exchanger capable of suppressing scattering of condensed water toward the downstream side in the air flow direction from the bent portion. The indoor heat exchanger (10) has lower fins (30) and upper fins (40). The upper fins (40) are inclined so that: the angle of the length direction of the upper fins (40) relative to the vertical direction and on the side of the air flow direction (F) is greater than or equal to the length direction of the lower fins (30) The angle with respect to the vertical direction, and the upper end portion of the upper fin (40) and the lower fin (30) are arranged adjacent to each other. Furthermore, the upper fin (40) has a curved bent portion (R) provided near the upper end of the lower fin (30) on the downstream side in the air flow direction (F).

Description

[0001] This application is national application number 200780026921.3 (the international application date is June 29, 2007, and the international application number is PCT / JP2007 / 063078), and the title of the invention is "heat exchanger, air conditioner and heat exchanger manufacturing method". Divisional application. technical field [0002] The present invention relates to a heat exchanger, an air conditioner, and a method for manufacturing the heat exchanger. Background technique [0003] 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. [0004] 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 t...
