The invention relates to an environmentally friendly low-noise shock-absorbing AC centrifugal fan, which includes a volute 1 and an impeller 2 placed in the volute. There is an axial flow air inlet and a centrifugal air outlet on the volute, and the volute is provided with the impeller. The middle tube is coaxially arranged, one end of the middle tube is connected with the volute, the impeller has a mandrel placed inside the middle tube, one end of the mandrel is connected with the impeller, the middle part of the mandrel is hinged with the middle tube through a sphere, and the core The other end of the shaft passes through the middle tube and is connected with a counterweight rotor; the middle tube has an iron core placed outside the middle tube, and windings are wound on the outside of the iron core, and the impeller is wrapped around the iron core. Peripheral rotor; the present invention utilizes ball joints to enable the mandrel to have the ability to deflect in all directions, which can convert the vibration into the axis deflection of the mandrel, and then use the angular momentum of the impeller and counterweight rotor to effectively buffer and counteract the deflection. Inhibition, so that the pressure on the internal parts is significantly reduced, reducing the wear and tear between the various parts.
Description
technical field [0001] The invention relates to airborne radar ventilation and heat dissipation equipment, in particular to an environmental-friendly, low-noise, shock-absorbing AC centrifugal fan. Background technique [0002] In order to meet the needs of air security, reconnaissance, surveying and mapping, etc., to ensure the accuracy of routes and flight safety, radars are widely used in various types of aircraft, especially military aircraft equipment; in order to enable airborne radars to obtain wider scanning coverage and For more accurate scanning results, the power of the airborne radar is high when it is working, and the equipment generates a lot of heat. Timely and effective heat dissipation is required to ensure that its temperature is normal and the radar can work normally. [0003] Airborne radar generally uses fan equipment for air-cooling and heat dissipation. Air-cooling heat dissipation needs to introduce external ambient air. During high-speed flight and m...
