축류팬Axial flow fan

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 증발냉각기의 일부인 모터고정대와, 모터 및 축류팬(axial flow fan)을 도시한 분해사시도.FIG. 1 is an exploded perspective view showing the motor stationary, the motor and the axial flow fan which are part of the evaporative cooler.

제2도는 축류팬의 정면도. 제3도는 축류팬과 모터 및 모터고정대를 도시한 부분단면 측면도.2 is a front view of the axial fan. 3 is a partial cross-sectional side view showing the axial fan, the motor, and the motor mount.

Claims (4)

모터를 모터고정대에 고정시키고, 모터축을 팬허브를 지지하도록 설치하며, 팬 날개를 팬허브로부터 방사상으로 배치시켜서 된 축류팬에 있어서, 상기의 팬허브를 중공의 접시형 부재로 구성시키되, 접시형부재에는 전방행으로 수렴하는 만곡선단부와, 고석 저압력 부위에서 만곡선단부를 경유하여 그의 내측으로부터 팬날개의 중공허브의 상류 외측까지 연장된 공기유출구를 형성시키고, 모터를 팬허브의 중공의 공간내에 적어도 일부가 들어가도록 배치시키며, 공기유입간극을 허브의 하류단부와 모터사이에 형성시키고허브와 모터 사이의 충분한 공간을 공기유입간극에서 공기유출구까지의 공기흐름 통로를 위해 형성된 축류팬.In an axial fan in which the motor is fixed to the motor holder, the motor shaft is installed to support the fan hub, and the fan blades are disposed radially from the fan hub, wherein the fan hub is composed of a hollow dish-shaped member. The member is formed with a curved leading end converging forwardly, and an air outlet extending from the inside thereof to the upstream outer side of the hollow hub of the fan blade via the curved leading end at the low pressure portion of the old stone, and the motor is placed in the hollow space of the fan hub. An axial fan formed with at least a portion therein, wherein an air inlet gap is formed between the downstream end of the hub and the motor and a sufficient space between the hub and the motor is formed for the air flow passage from the air inlet gap to the air outlet. 제1항에 있어서, 증발냉각기의 일부인 상기의 모터고정대를 축축한 증발패드의 하류에 위치시켜 모터와 팬을 지나는 공기를 냉각시키며, 상기 패드로부터 습기 입자를 혼입할 수 있도록 구성시켜서 된 축류팬.The axial flow fan according to claim 1, wherein the motor stopper, which is a part of the evaporative cooler, is positioned downstream of the moist evaporation pad to cool the air passing through the motor and the fan, and is configured to incorporate moisture particles from the pad. 제1항 또는 제2항에 있어서, 상기 허브의 선단부를 도움형으로 형성시키고, 허브의 나머지 부위를 원통형으로 형성시키며, 상기의 고속 저압력 영역을 허브의 도움형 선단부와 원통형부위 사이의 전이영역부근에 형성시켜서 된 축류팬.3. The method of claim 1 or 2, wherein the tip of the hub is formed in a helper shape, the rest of the hub is formed in a cylindrical shape, and the high speed low pressure region is a transition region between the helped tip of the hub and the cylindrical part. An axial flow fan formed in the vicinity. 제1항 또는 제2항에 있어서, 상기의 모터가 전·후방으로 돌출되는 모터축을 갖도록 하며, 상기의 허브를 모터축의 전방 돌출단부에 설치시켜서 된 축류팬.The axial flow fan according to claim 1 or 2, wherein the motor has a motor shaft protruding forward and rearward, and the hub is provided at the front projecting end of the motor shaft. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
