Abstract
본 발명은 전자레인지 등에 적용되는 축류팬에 관한 것으로, 원통의 허브에 5개의 블레이드를 일정 간격을 두고 형성하고, 그 블레이드의 내외경비(팬허브경÷팬외경)를 0.28~0.35로 설정하여, 보다 낮은 회전수에서 냉각 성능을 만족시키면서 소음을 저감시키도록 한 것으로, 소음 실험에 의하면 현재 양산중인 M모델에 적용한 기존 축류팬(3020rpm)의 평균 소음값은 46.06dB(A)인 반면에, 본 발명의 축류팬(2400rpm)의 평균 소음값은 41.88dB(A)이고, 또한 현재 개발중인 A모델에 적용한 기존 축류팬(2350rpm)의 평균 소음값은 43.24dB(A)이고, 본 발명의 축류팬(2145rpm)의 평균 소음값은 39.47dB(A)로서 약 3.8dB(A)정도의 소음 저감 효과를 얻을 수 있다.The present invention relates to an axial flow fan applied to a microwave oven and the like, five blades are formed in a cylindrical hub at regular intervals, and the inner and outer ratios (fan hub diameter ÷ fan outer diameter) of the blade is set to 0.28 ~ 0.35, In order to reduce the noise while satisfying the cooling performance at a lower rotational speed, the noise test shows that the average noise value of the existing axial fan (3020 rpm) applied to the M model in mass production is 46.06 dB (A). The average noise value of the axial fan (2400 rpm) of the invention is 41.88 dB (A), and the average noise value of the existing axial fan (2350 rpm) applied to the A model currently being developed is 43.24 dB (A), and the axial fan of the present invention. The average noise value of (2145 rpm) is 39.47 dB (A), and a noise reduction effect of about 3.8 dB (A) can be obtained.
