Abstract

The utility model relates to a wind wheel of a fan coil, which is composed of two end disks, middle disks and a plurality of vanes. The utility model is mainly characterized in that the fixed ends of the two end disks are used for wrapping the outer surfaces of both ends of each vane in a rotation way to be fixedly connected with the vanes; symmetrical middle disks with double shaft sleeves, which are in the shape of a circular arc and are used for transmission, are axially pressed and fixedly connected with the vanes without a gap. Thus the utility model has the advantages of firm fixation of the vanes of the wind wheel, reduced vortex flow, reduced noise, obviously improved mechanical property and air property, high efficiency, long service life and beautiful appearance, and is widely used for the blowing of a fan coil of a central air conditioner.

Description

Fan-coil wind wheel

The utility model relates to a kind of air-conditioning wind wheel, is specifically related to a kind of Fan-coil wind wheel.

The Fan-coil wind wheel of prior art is that mid-game is identical with two end plate outside dimensions, web upper punch at mid-game and two end plates has the vanes fixed hole, blade is a strip, the blade transverse section is curved, the blade two ends are fixed end, and the vanes fixed end passes the vanes fixed hole of two end plates respectively, then gapped compressing on the mid-game web, again with vanes fixed end discount on the outer surface of end plate, the web of two end plates is curling shape.Its structural manufacturing process is simple, but because vanes fixed is insecure, the rigidity of wind wheel, intensity difference, radially big with end face run-out, cause wind wheel mechanical property and aerodynamic quality poor, noise is big, and the life-span is short.

The purpose of this utility model provides a kind of Fan-coil wind wheel, and its mechanical property and aerodynamic quality obviously improve, and noise is low, and the life-span prolongs, and attractive in appearance.

For achieving the above object, Fan-coil wind wheel of the present utility model is made up of mid-game and some blades of two end plates and a double as transmission, blade is a strip, the blade transverse cross-sectional profile is curved, respectively there is the fixedly facet perpendicular to the blade body at the two ends of blade, the web of mid-game is a fixed end, the web of two end plates is a fixed end, the fixed end of two end plates radially revolves the outer surface that encases the blade two ends respectively on circumference, the web of two end plates is the bound edge shape, then mid-game is packed into center fixed position in the impeller, axial compression does not have the affixed blade in gap again.

Described blade two ends can respectively be drawn perpendicular to three of the blade body fixing facets and be parallel to two of the blade body fixedly facets.

Described mid-game can be formed by being circular arc and two disks of symmetry and the axle sleeve of two band taperings, be evenly equipped with some radially cutting off and the axial curved vanes fixed seam of perk on the mid-game web circumference, there is little round tube hole vanes fixed seam lower end, and the distance between two axle sleeves of mid-game center is according to the decision of strength size.

Described mid-game can also be made up of a disk and an axle sleeve, is evenly equipped with some radially cutting off and the axial curved vanes fixed seam of perk on the mid-game web circumference, and there is little round tube hole vanes fixed seam lower end.

The fixedly corresponding cavity of facet of a shape, size and blade two ends is arranged on the fixed end circumference of described two end plates, and the fixedly facet at blade two ends just in time is positioned at this cavity during connection.

After adopting said structure, because that mid-game and blade axial compression do not have the gap is affixed, mid-game is the symmetric double arc-shaped surface, makes the wind wheel blade fixation, and eddy current reduces, the noise minimizing, and mechanical property and air performance obviously improve.Can raise the efficiency like this, life-saving, and outward appearance is beautiful, is widely used in the fan coil unit air-supply of central air-conditioner.

Below in conjunction with accompanying drawing the utility model Fan-coil wind wheel is described further:
