ット７は熱交換器４と送風ファン６を収納している。EXAMPLES Hereinafter, examples of the present invention will be described based on the drawings. 1st
In the drawings and FIG. 2, reference numeral 1 denotes a flat heat exchanger tube arranged vertically, and fins 2 are alternately arranged with the flat heat exchanger tubes 1 and joined by brazing. Upper header pipe 3 having bent portion 5A
The upper end of the flat heat exchanger tube 1 is connected to the portion of the lower header tube 3B having the bent portion 5B excluding the bent portion 5A, and the lower end of the flat heat exchanger tube 1 is connected to the portion of the lower header tube 3B having the bent portion 5B excluding the bent portion 5B. It consists of A blower fan 6 is positioned in front of the heat exchanger 4 to exchange heat through forced convection. The outdoor unit 7 houses a heat exchanger 4 and a blower fan 6.
熱交換器４は曲かり部５Ａ、５Ｂが１ケ所有り、平板状
のものと比較してその前面面積は大きくなっている。し
かもその曲がり部５Ａ、５Ｂには偏平伝熱管Ｉが連続さ
れていないので通風抵抗が増大するもない。The heat exchanger 4 has one bent portion 5A, 5B, and its front surface area is larger than that of a flat plate-shaped one. Furthermore, since the flat heat exchanger tubes I are not continuous in the bent portions 5A and 5B, there is no increase in ventilation resistance.
従って、熱交換器４の前面面積が大きくなったことによ
り通風抵抗が軽減でき、送風ファン６の運転回転数を小
さくでき騒音低減が図れる。また、熱交換器４の放熱能
力が増大するので熱交換器４の凝縮温度を低く設定でき
、室外ユニット７のＣＯＰ同上が図れる。Therefore, since the front surface area of the heat exchanger 4 is increased, ventilation resistance can be reduced, and the operating speed of the ventilation fan 6 can be reduced, thereby reducing noise. Further, since the heat dissipation capacity of the heat exchanger 4 increases, the condensing temperature of the heat exchanger 4 can be set low, and the COP of the outdoor unit 7 can be increased.

Ｐ向上が図れる。(1) At least one bent part is provided in the upper header pipe and the lower header pipe in correspondence with each other, and a flat heat exchanger tube is connected to the part excluding the bent part, and fins are arranged alternately and joined to the flat heat exchanger tube by brazing. This improves the storability of the heat exchanger in the outdoor unit and allows the front surface area of the heat exchanger to be increased without increasing ventilation resistance. As a result, the operating speed of the blower fan can be reduced, reducing noise. Also, the heat dissipation capacity of the heat exchanger is increased, and the degree of condensation can be set low, allowing the outdoor unit to reduce CO2 emissions.
P can be improved.
