Definitions

  • the present invention relates to a fan component, and more particularly to a cross-sectional composite fan blade that provides both vertical and horizontal wind.
  • a fan is a type of air supply device, and the output of the wind accelerates the flow of air to provide a heat dissipation effect. More commonly used is an axial flow fan that axially discharges a pressurized air stream.
  • the blades of an axial fan are typically comprised of rims and blades spaced equidistantly spaced around the circumference of the rim. When the blade rotates, the blades provided on the periphery of the rim perform the wind-lifting lift of the gas, and the generated wind pressure and flow rate are discharged from the axial direction of the blade.
  • There is also a cross flow fan which can discharge the pressure air flow laterally, and the blades of the cross flow fan are arranged on the surface of the rim at the same time.
  • the technical problem to be solved by the present invention is to make up for the defects of the prior art, and propose a vertical and horizontal composite fan blade which can simultaneously provide axial air supply and lateral air supply.
  • the vertical and horizontal composite fan blade comprises: a rim and an axial wind blade disposed at an equidistant distance on a circumference thereof, wherein the axial end of the axial wind blade is connected with a base ring integrated therewith, surrounding the surface of the base ring
  • the lateral wind blades are arranged at intervals.
  • the vertical and horizontal composite fan blade of the invention has scientific design, reasonable structure and simple structure. It combines the lateral blades commonly used as blowers with the blades of a typical fan to integrate a blade that provides axial airflow for lateral air supply. On the basis of not changing the original axial air supply, the fan blade increases the lateral air supply, which not only greatly expands the fan fan wind surface, but also increases the fan air volume output. The applicable environment has been greatly expanded, and the efficiency of the wind has also been greatly improved.
  • Figure 1 is a schematic view showing the structure of a vertical and horizontal composite fan blade.

  • the blade 2 constitutes an axial fan blade
  • the transverse fan blade 3 is constituted by a base ring 31 and lateral wind blades 32 equally spaced on the surface thereof.
  • the base ring 31 of the transverse fan leaf ring 3 is sleeved on the outer end of the blade 2 of the axial fan blade, and is fixedly connected to form an integral body.
  • the rim 1 is provided with a motor assembly mounting cavity.
  • the principle of air supply of the vertical and horizontal composite fan blades When the blades rotate, they are placed on the rim circumference The blade of the edge performs the wind-lifting work of the gas, and the generated wind pressure and the flow rate are axially discharged; the blade disposed on the surface of the base ring is subjected to suction and centrifugal discharge work, and the generated wind pressure and flow diameter are generated.

Abstract

L'invention concerne un ventilateur combiné pourvu de pales à flux axial et à flux transversal, lequel ventilateur présente un moyeu et plusieurs pales à flux axial disposées à équidistance autour du moyeu. Un anneau de base est relié d'un seul tenant à l'extrémité de la pale à flux axial. Les pales à flux transversal sont disposées à équidistance autour de la surface de cet anneau de base. Le ventilateur combiné de ladite invention est de conception scientifique et sa configuration est simple et rationnelle. Il fournit un vent aussi bien axial que transversal grâce à la combinaison intelligente des pales à flux transversal de la soufflante et des pales du ventilateur général. Sans changer le sens de soufflage axial initial, ce ventilateur peut également augmenter le vent transversal, la surface de dissipation thermique et le débit de ventilation. Ce ventilateur combiné convient à un grand nombre d'applications et peut augmenter considérablement le débit de vent.
