Abstract
The utility model discloses the double-deck fan of the two wind path of a kind of motor, this double-deck fan is made up of outer cone ring, fan blade, interior conical ring, fan shroud etc., twice wind path mouth is become with interior conical ring by outer cone ring, one tunnel is as the wind path passage between motor stator and support, one tunnel, as the wind path passage between motor stator and rotor, is avoided motor two-way air channel to collect a place and is produced eddy current.Technique effect of the present utility model is: (1) is avoided different wind path to collect a place and formed eddy current, reduces windage; (2) shorten the air draft path of motor, improve radiating efficiency (3) simplification manufacturing procedure, fitting operation is convenient, reliability is high.
Description
Technical field
The utility model relates to a kind of motor radiating fan, is specifically related to the double-deck fan of the two wind path of a kind of motor.
Background technology
The fan Main Function of motor makes motor internal gas flow, makes to carry out heat exchange as the internal gas of heat carrier and extraneous gas, keeps the temperature rise of motor to be stabilized in claimed range.The fan of motor is as the primary drive part of gas flow, by the High Rotation Speed of self, effect by centrifugal force produces blast, make motor internal gas discharging to outside motor, simultaneously ambient atmos enters motor internal, reaches the circulation of internal gas and ambient atmos, the heat of motor by gas as carrier, carry out exchange heat with the external world, ensure the temperature rise of motor with this.The temperature rise height of motor plays the quality certainly in motor internal gas and the ambient atmos circular flow general character.The quality of the gas flow general character rises again certainly in the quality of fan, and this just requires to study high efficiency fan.
Summary of the invention
The purpose of this utility model is the double-deck fan providing the two wind path of a kind of motor, and the double-deck fan rapid heat dissipation of this pair of wind path, reliability are high, have the air draft of twice wind path, shorten air draft path, improve fan efficiency.
The utility model realizes like this; a double-deck fan for the two wind path of motor, mainly comprises outer cone ring, fan blade, interior conical ring and fan shroud, it is characterized in that: this double-deck fan is a single-casting; by outer cone ring and interior conical ring, fan blade is divided into two parts, forms twice wind path; Fan shroud becomes a wind path with interior conical ring, this wind path is mainly as the wind path passage between motor stator and support, interior conical ring and outer cone ring form another wind path, and this wind path is as the wind path passage between motor stator and rotor, and twice wind path avoids motor two transportation work style and collects place's formation eddy current, reduce windage, in addition, because interior conical ring can play reinforcement effect, therefore fan shroud internal diameter can increase, thus increase wind inlet of fan, shorten the air draft path of motor.
The internal diameter of fan shroud described in the utility model designs according to actual conditions, can increase fan shroud internal diameter, thus increases wind inlet of fan.
Advantage of the present utility model: conical ring in the double-deck fan of two wind path adopts and increases, becomes twice wind path mouth by outer cone ring with interior conical ring, avoids motor two transportation work style and collects place's formation eddy current, reduce windage.Strengthen fan intensity effect because interior conical ring can play, therefore fan shroud internal diameter can increase, thus increase wind inlet of fan, shorten the air draft path of motor, improve fan efficiency.

Fig. 1 is the front view of double-deck fan of the present utility model.
Fig. 2 is the left view of double-deck fan of the present utility model.
Fig. 3 is air channel of the present utility model schematic diagram.
In the drawings, 1, outer cone ring; 2, fan blade; 3, interior conical ring; 4, fan shroud, 5, support, 6, stator, 7, rotor.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model comes work and enforcement like this, the double-deck fan of the two wind path of a kind of motor, mainly comprise outer cone ring 1, fan blade 2, interior conical ring 3 and fan shroud 4, it is characterized in that: this double-deck fan is a single-casting, by outer cone ring 1 and interior conical ring 3, fan blade 2 is divided into two parts, forms twice wind path; Fan shroud 4 and interior conical ring 3 form a wind path, this wind path is mainly as the wind path passage between motor stator 6 and support 5, interior conical ring 3 and outer cone ring 1 form another wind path, and this wind path is as the wind path passage between motor stator 6 and rotor 7, and twice wind path avoids motor two transportation work style and collects place's formation eddy current, reduce windage, in addition, because interior conical ring can play reinforcement effect, therefore fan shroud internal diameter can increase, thus increase wind inlet of fan, shorten the air draft path of motor.
Claims (2)
