Add, motor position has adjusted, fan blade shape changes novel fan, it can be applicable to most of cooling device, heat radiation
Property is good, work efficiency is high, enhances the protective effect to motor, and processing technique is simple, with low cost, has great city
Field promotional value.
To achieve these goals, the technical solution of the utility model is as described below:
A kind of wing type fan for cooling device, including air duct, fan blade, base plate and motor, wherein base plate is arranged on
The bottom of air duct, and air duct by base plate be connected to cool down cabinet top, air duct is arranged on the outside of fan blade, and fan blade is fixed
Being arranged on motor, described motor is fixed on air duct inside by bracing frame and is arranged on the surface of fan blade, described air duct
It is highly 450-550mm；
Preferably, the height of above-mentioned air duct is 450-500mm；
Preferably, above-mentioned fan blade is airfoil type, and the molded line of its blade upper surface and blade lower surface is arc；
It is highly preferred that above-mentioned fan blade uses aluminum alloy materials to make；
Most preferably, above-mentioned air duct uses aluminum-zinc alloy, rustless steel or fiberglass to make.
Compared with the old-fashioned blower fan that wing type fan provided by the utility model is common with prior art, exist as
Lower technical advantage:
(1) the many employings of old-fashioned blower fan short air duct form, owing to the height of air duct is the most relatively low so that blower fan is in work process
Middle blast is relatively low, and air draught power is more weak, is difficult to discharge the hot-air of evaporation；Wing type fan provided by the utility model is by wind
Cylinder highly increases to 450-550mm, under conditions of not increasing power of motor, increases air quantity and the blast of blower fan, and then makes
The work efficiency obtaining blower fan is greatly improved.
(2) the motor major part of old-fashioned blower fan is installed on box house, it is not easy to self-radiating, and motor is easily damaged, the longevity
Order shorter；Motor is installed on the casing upper top of cooling cabinet by wing type fan provided by the utility model, owing to being positioned at
The outside of casing so that can preferably play the thermolysis to motor while blower fan work, thus the use longevity of motor
Life is extended.
(3) fan blade of old-fashioned blower fan is generally linear type or common arc, sector, air velocity, airflow pressure with
And work efficiency is the most relatively low；Fan blade is designed to the shape of aviation wing by wing type fan provided by the utility model, increases
The pressure reduction of fan blade lower surface and upper surface, when blade rotates, air has component upwards and surface velocity fast along cambered surface, from
And make the air velocity in air duct accelerate, on the premise of not changing power of fan, improve the effect of blower fan heat extraction.Additionally, wind
The material selection aluminum alloy material of leaf, lightweight, the workload of motor can be reduced.
