Embodiment Construction
[0019]DETAILED DESCRIPTION OF THE DRAWINGS The specific embodiments of the present invention will be further described below with reference to the drawings.
[0020]byFigure 1 to 13It is given, the present invention includes a casing 1, a fan 2 is provided on the inside of the casing 1 and a multi-stage wide-frequency outer rotating alternating current motor 3 for driving the fan 2, and there is a fan 2 axial direction on both sides. The air outlet 4 and the intake port 5 have a rotary ring 6 placed in the inner side of the air opening 4 and rotatably rotatable with the casing 1 along the axis of the fan 2, and the inside of the rotary ring 6 is along the rotary ring 6. Several three prism 7 of the axis circumference, the triangular bottom surface of the triangular prism 7, and either side surface of the triangular prism 7 and the radially perpendicular to the rotary ring 6, and the three adjacent sides of the side. The other side of the prism 7 copies and seals the sliding connection,...

The invention relates to a multi-slot, multi-pole, and broadband externally-rotating AC heat-dissipating axial-flow fan. There are several triangular prisms with uniform circumferences on the inner side of the rotary ring, and the bottom surface of the triangular prism is arranged horizontally. Any side surface of the triangular prism is perpendicular to the radial direction of the swivel ring, and the any side surface is coplanar sliding connection with the other side surface of the adjacent triangular prism on one side, so that the plurality of triangular prisms are sealed and slid through the adjacent side surfaces in turn. connected to form a circular polygonal channel; the triangular prism and the casing are slidably connected on the horizontal plane, and the triangular prism and the swivel ring are hinged through the connecting rod, so that when the swivel ring is rotated, the triangular prism is driven by the connecting rod to produce sliding; the invention The diameter of the air duct can be changed in real time to ensure that the air flow inside the fan is in a laminar flow state and prevent stalling.
Description
Technical field[0001]The present invention relates to an alternating fan, in particular a multi-slot multipole number, wide frequency external to an alternating heat-dissipating hot shaft fan.Background technique[0002]The main function of the fan is ventilated heat, in the normal use environment, its performance is stable, the noise and vibration during operation are small, but in some special conditions such as the airborne radar cooling system, it has a high altitude during the flight during the flight. The multi-chaotic current is incompetent, so the high-altitude work environment has a large impact on the fan generated, especially during the aircraft mobile, the instantaneous pressure change is extremely easily causing the fan atmospheric or causes breathable, so that the fan does not work properly. Not only will it seriously affect the normal use of the airborne radar, but also cause mechanical damage to the fan, which will cause the fan failure to bring safety hazards.Inventiv...
