Description

A kind of fan housing and motor device
Technical field
The utility model relates to motor field more particularly to a kind of fan housings and motor device.
Background technique
Direct current permanent magnet motor is exactly a kind of energy-efficient product.But it is integrated in the control system on direct current permanent magnet motor Circuit board (frequently referred to controller) is easy fever and high temperature is caused to burn out.Typically just cooled down with built-in radiator fan, is dissipated because built-in Hot-air fan device box will expand, and wiring point increases again, installation trouble, and power supply strength has been lost, another radiator fan fan It itself can often generate heat and burn out the controller for leading to direct current generator also with burning out.
Utility model content
The purpose of this utility model is that in place of solving the above deficiencies in the existing technologies.
To achieve the above object, on the one hand, the utility model provides a kind of fan housing, including round fan housing ontology, round wind The right side port of cover body is provided with fan housing air inlet hole, and the left side port of round fan housing ontology connects motor housing, in round wind Square air channel is provided on the arc-shaped side of cover body;The lower end of square air channel is connected to round fan housing ontology, and is integrally formed, side Terminal box where the left end connection controller in shape air duct, square air channel are used to connect from the cold wind of round fan housing ontology guiding Wire box.
Preferably, fan housing is made of carbon steel.
On the other hand, the utility model provides a kind of motor device, including terminal box, motor and as described in relation to the first aspect Fan housing, wherein the fan blade of motor is extend into fan housing, and terminal box is located above motor, is provided with controller in terminal box.
The utility model increases air duct on original arc-shaped side, the wind under the high-speed rotation of fan blade, i.e., cooling motor Wind is diverted on controller by square air channel again, eliminates original radiator fan in terminal box.As long as motor is operating, The refrigerating function of controller is also protected always, and cooling wind-force is big, and effect is good, and structure is simple, easy for installation, cost It is low.

Specific embodiment
With reference to the accompanying drawings and examples, the technical solution of the utility model is described in further detail.
Picture 1-4, the utility model embodiment provides a kind of fan housing 1, including round fan housing ontology 11, round fan housing ontology 11 right side port is provided with fan housing air inlet hole 111, and the left side port of round fan housing ontology 11 connects motor housing 5, in circle Square air channel 12 is provided on the arc-shaped side of fan housing ontology 11.
The lower end of square air channel 12 is connected to round fan housing ontology 11, and is integrally formed, the left end connection of square air channel 12 Terminal box 7 where controller 3, square air channel 12 is used for will be from 3 place of cold wind guide controller of round fan housing ontology 11 Terminal box 7.
In one example, fan housing 1 is made of carbon steel.
Such as Fig. 3, the fan blade 2 being connected on motor shaft 6 is located at the inside of round fan housing ontology 11,6 band of motor shaft of motor Dynamic fan blade 2 rotates, and in the natural wind inspiration circle fan housing ontology 11 on right side, will inhale wind a part in the round fan housing ontology 11 of gold Continuation is flowed to the left, is cooled down to motor, another part flows up, and by square air channel 12, terminal box 7 is blowed to, to control Device processed is cooled down.The direction of arrow represents the flow direction of wind in Fig. 3.
Wherein, as shown in figure 4, right side is provided with the terminal box air inlet 71 of connection square air channel 12, left side is set cable concentrator 7 It is equipped with terminal box exhaust vent 72, bottom is provided with cooling fin installing port 73, cooling fin 4 is equipped on cooling fin installing port 73, dissipates Backing 4 is equipped with controller.
As long as motor is operating, the cooling of wind also exists always.It is tested by practical application, is existed with the temperature of radiator fan Between 50 ° to 60 °, and there was only about 40 ° with the operating temperature of shunt heat dissipation air hood air inducing cooling controller, cooling effect is excellent More.
With shunt heat dissipation air hood cooling down controller instead of radiator fan, the volume of device can is reduced, is subtracted Therefore small material reduces costs.
Above specific embodiment has carried out further the purpose of this utility model, technical scheme and beneficial effects It is described in detail, it should be understood that the above is only the specific embodiments of the utility model, is not used to limit originally practical Novel protection scope, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done, It should be included within the scope of protection of this utility model.
