Abstract
본 발명은 횡류팬에 관한 것으로, 종래의 그 외주각의 범위에서 리어가이더의 형상에 따라 소음특성 및 풍량특성이 달라지게 되는 문제점이 있어 리어가이더의 형상에 구애되지 않고 양호한 소음특성 및 풍량특성을 갖도록 하는 외주각을 갖는 횡류팬에 관한 것이다. 이와 같은 횡류팬(10)은 팬 외경원에서의 접선과 날개(11)의 원호와 팬 외경원이 만나는 점에서의 외접선 사이의 각도인 외주각(ω)이 20∼25°사이의 값을 가지도록 형성된다. 상기와 같은 본 발명에 의하면 공기조화기의 디자인의 변경등의 이유로 리어가이더(4)의 형상이 변화하더라도 항상 고풍량 저소음 특성을 유지할 수 있게 되고, 공기조화기의 각 모델에 대해 한 종류의 횡류팬을 사용 할수 있어 제조원가가 절감되는 효과가 있다.The present invention relates to a crossflow fan, which has a problem in that the noise characteristics and the air volume characteristics vary depending on the shape of the rear guider in the range of the conventional peripheral angle, so that the sound noise characteristics and the air volume characteristics are not limited to the shape of the rear guider. A crossflow fan having an outer circumferential angle to be provided. Such a cross flow fan 10 has a value between 20 and 25 ° of an outer circumferential angle ω, which is an angle between a tangent line at a fan outer circle and an circumference at the point where the circular arc of the blade 11 and the fan outer circle meet. It is formed to. According to the present invention as described above, even if the shape of the rear guider 4 is changed due to a change in the design of the air conditioner, it is possible to maintain high air volume and low noise at all times, and there is one type of cross flow for each model of the air conditioner. The fan can be used to reduce manufacturing costs.
