[0002] Vortex high pressure fan, also called high pressure vortex fan, is a new type of air source generating equipment with compact structure, small volume and light weight. When the impeller of the fan rotates, the blades on the impeller will rotate with the air. Due to the centrifugal force, the air is pushed to the edge of the impeller and returns to the impeller along the annular cavity of the pump body, forming a circulating air flow. This circulating air flow is uniformly accelerated in the process of impeller rotation, and finally escapes from the pump body in the form of a spiral line, producing high pressure air flow.
[0003] When the fan blades rotate, friction or impact with air will occur, which will produce noise. The faster the rotation speed, the higher the frequency of contacting air, and the more acute the noise. When the width or thickness of the blades increases, the friction and impact phenomenon is more obvious.
