Description
Technical field
The utility model relates to a kind of air discharge structure, relates in particular to a kind of quiet unit baffler and forces air discharge structure.
Background technique
At present, traditional type of cooling of middle and small motor is that employing is air-cooled, and along with development of technology and development, speed-adjustable motor obtains increasing use; And air cooling way exists certain problem for the cooling of speed-adjustable motor, and in the air cooling equipment of motor, fan blade all is mounted on the motor shaft; By the motor shaft driven rotary, realize self cooling, when motor is under the tick-over state; No matter be step speed regulation or stepless time adjustment, the fan blade rotating speed that is installed on the motor shaft can descend greatly, and motor temperature remains on about 90 ℃ after thermally-stabilised; Have a strong impact on the motor cooling effect, the motor of long-term work under the low speed situation especially, its air cooling effect does not almost have; Motor can not get cooling for a long time, and heat can not get effective bulk storage, and the causes motor insulating strength reduces; The fusing of motor bearings lubricant grease, electrical machinery life shortens, and this kind can not satisfy the normal need of motor cooling from the cooling technology.
At present, the part producing producer of domestic electric machine has adopted hydraulic generator independently to drive and the heat absorbing type heat radiation in radiation system; But special island wind apparatus is not arranged, still carry out wind-guiding, but the heat that can not effectively blower fan be discharged is like this discharged outside the hood with the barge board between radiator and the motor; Also can cause air turbulence between radiation system and the motor, air draft is not smooth, causes high temperature position temperature such as baffler, cylinder cap, motor; Constantly raise; Heat can not get effective discharging, greatly influences the working environment of motor, has increased drawbacks such as power loss.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of quiet unit baffler to force air discharge structure, has that topology layout is reasonable, easy and simple to handle, air draft is respond well, stability is high, the electric efficiency advantages of higher.
The utility model is to realize through following technological scheme:
Quiet unit baffler is forced air discharge structure; Its by: motor intake grill, start and draw parts formations such as cover, baffler guard shield, muffler, outer cover guard shield, outer cover guard shield relief opening, baffler relief opening, housing on dish, motor wind scooper, the motor wind-guiding; The motor intake grill is arranged at a side of housing; One end of motor wind scooper and startup draw dish fixing, are covered with the upper end that places the motor wind scooper the other end on the motor wind-guiding, and the outside of muffler is provided with the baffler guard shield; Muffler is fixed through outer cover guard shield and housing, and outer cover guard shield relief opening and baffler relief opening are arranged at the opposite side of housing.
Described motor intake grill, it is set to square hole vertical bar shape, draws dish to be in over against the position with startup.
Dish is drawn in described startup, is provided with many air channels.
Described muffler is " protruding " type, and its external part is the baffler relief opening, and is gapped between muffler and baffler guard shield, is convenient to the circulation of air.
Described outer cover guard shield relief opening, it is set to square hole slanted bar shape, is in over against the position with muffler.
The utility model workflow is: engine operation drives the rotation of flywheel fan blade; Draw the dish air channel to suck cool air from the unit outside through motor intake grill, startup, the motor of flowing through is through the motor wind scooper; Produce the part heat when taking away engine operation; The heat that baffler conduction, radiation produce is taken away in the space between muffler and the baffler guard shield of flowing through again again, and it is outside to discharge unit; Simultaneously, the baffler vent systems produces most of heat outside outer cover guard shield relief opening is discharged unit with the motor work done, thereby accomplishes the pressure air draft of quiet unit baffler part.
Owing to adopted above technological scheme, the utlity model has following beneficial effect and be:
Use this structure can effectively reduce high temperature position temperature such as baffler, cylinder cap, motor, the highest reduction temperature reaches more than 55%, has greatly improved the working environment of motor, has reduced power loss effectively, has improved the useful horsepower of motor.
