Abstract
A single-motor dual-impeller fan belonging to fan technology includes a motor, a motor shell, impellers and an air inlet and an air outlet which are arranged on the fan shell. The fan shell which is fixedly connected to the shell of the motor as well as the air inlet and the air outlet have two in number; the impellers arranged on the shaft of the motor also have two in number. Two impellers are respectively arranged in two fan shells; one of the impellers is a left screw impeller, and the other impeller is a right screw impeller. A clapboard is arranged between the two fan shells. The motor can be arranged in the two fan shells and between the two impellers; the clapboard is fixed on the shell of the fan; the shaft of the motor is extended at two sides of the shell. The motor can also be arranged at one side of the two fan shells and two impellers; the clapboard is fixed to the two fan shells; the shaft of the motor is extended at one side of the shell. The utility model can carry out relative air inlet and outlet operations, and has the functions of dual-way wind reversion or relative cooling, etc. and can be widely applied to air conditioners, large-scale wind cooling transformer and other devices which require the wind cooling heat dissipation.
Description
Technical field
The utility model belongs to the blower fan technical field, more particularly relates to the air intake or the design of single motor bilobed wheel blower fan of air-out relatively relatively.
Background technique
Traditional blower fan mostly is unidirectional outlet and inlet.During work, wind constantly enters from the front or the back of blower fan, again from its back or the front flow out.91106574.1 the patent application of number by name " ball-type omnidirectional electrical fan " discloses a kind of spherical electric fan that can three direction air-out, it can make the almost all people who is positioned at room 360 degree scopes all blow to cool breeze.But it is to form three fans with each self-driven impeller of three motors in fact, 120 degree that again center line of three fans intersected each other, uniform being installed in the 360 degree scopes.Therefore, it is actually the combination of three fans.Its cost of production, production technology etc. all improve a lot.The Chinese patent of No. 93214378 " but two air intake break-in low noise centrifugal blowers " by name discloses a kind of two air intake blower fans that have two impellers.But it is to have installed transmission device additional between motor and two impellers, so its cost of production also improves a lot.
In some cases, single motor bilobed wheel blower fan of air intake or opposing air-out can provide in demand convenience for relative assembly or equipment relatively, obtains beyond thought effect.
The purpose of this utility model, just be to overcome above-mentioned shortcoming and defect, a kind of air intake relatively or air-out relatively are provided, for relative assembly or equipment provide two-way to change functions such as wind or two-way cooling, reduce volume, relatively low cost of production is arranged, obtain single motor bilobed wheel blower fan of good result.
Summary of the invention
In order to achieve the above object, the utility model comprises motor, is connected in Blower Housing on the shell of motor, the axle that is installed in motor is gone up and be arranged in the impeller of Blower Housing and be installed in intake grill and exhaust outlet on the Blower Housing.The Blower Housing that is connected on the shell of motor respectively has two together with its intake grill and exhaust outlet, and the impeller that is installed on the axle of motor also has two.Two impellers lay respectively in two Blower Housings.Have isolating plate between two Blower Housings.
During work, because two impellers install, are fixed on the same motor shaft, thus reduced cost of production, and air intake or relative air-out relatively.
Motor can be positioned at the centre of two Blower Housings and two impellers, and isolating plate is fixed on the shell of motor, and the shaft extension of motor goes out in both sides.Isolating plate can be isolated air-flow, avoids air-flow to interfere with each other.Motor is positioned at the centre of two Blower Housings and two impellers, and this is a kind of than symmetrical structure, and it is more stable to work, and parts are stressed also more even.
Motor also can be positioned at a side of two Blower Housings and two impellers, and isolating plate is fixed on two Blower Housings, and the shaft extension of motor goes out in the one side.The shell of two Blower Housings and motor is fixed on the same support.This is a kind of dissymmetrical structure, also needs in some cases.
Two outsides that two intake grills can be positioned on the center line of motor, Blower Housing is relative.Two exhaust outlets are positioned at the avris of Blower Housing.Two impellers are done corresponding installation, that is air intake is installed relatively.
Two intake grills also can be positioned at the avris of Blower Housing, two outsides that two exhaust outlets are positioned on the center line of motor, Blower Housing is relative.Two impellers are done corresponding installation, that is air-out is installed relatively.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of air intake relatively or relatively air-out, for relative assembly or equipment provide two-way to change functions such as wind or opposing cooling, reduces its volume, reduces production costs, and obtains single motor bilobed wheel blower fan of beyond thought effect.It can be widely used in the equipment of air conditioner, large-sized wind cooling transformer and other need wind-cooling heat dissipating.
