The motor fan 2 coaxial with the motor 1 obtains outside cold air through the second air inlet 9, and after the cold air absorbs heat of the motor 1, the first side plate 17 and the ceiling 16 are both closed and have no opening, so that the cold air cools the motor 1 and then becomes hot air to be left in the mounting cavity.

The control unit 6 sucks in fresh air through the first air inlet 8 on the first end plate 71 to dissipate heat of the frequency converter and the electronic components, and then the hot air is also discharged into the installation cavity through the control heat dissipation port 11.

The oil cooling fan 4 at the front end of the oil cooler 3 sucks in fresh air through the third air inlet 10, and hot air also enters the installation cavity after taking away heat of the lubricating oil liquid cooled by the oil.

The hot air is directly absorbed by the air filter 12, and through tests, the temperature of the air entering the air filter 12 is 8-10 ℃ higher than that of the outside air. The air, after being filtered of impurities, enters the compression unit 14 for compression. The pressure fluctuation level is then reduced by the silencer 5, and finally the compressed air is delivered to other systems through the compressed gas outlet 19. The first baffle 131 and the second baffle 132 are arranged around the gas filter 12 in the direction close to the first side plate 17, which is beneficial to noise reduction at the sound source.

According to the utility model discloses the overall arrangement mode of air-blower can keep the flow and the energy efficiency level that should have, can reduce 8-9dB (A) simultaneously on complete machine noise amplitude. Through the calculation of the whole air suction volume, the air volume required by the compressed air can be satisfied by the air inlet volumes of the first air inlet 8 and the second air inlet 9, the condition of back pressure (the occurrence of the back pressure can lead to insufficient cooling of a motor or lubricating oil) can not occur, and after the third air inlet 10 is added, the air inlet volume is further satisfied, and the back pressure can not occur. The whole sealing performance of the box body is good, only a small amount of air inlet grids are exposed, and the path that sound radiates outside the box body in the running process of the air blower is favorably reduced. The blower is compact in structure and higher in integrity, and does not need to be matched with an additional rainproof and dustproof cover when being used under a common condition.

According to the utility model discloses air-blower, the fuselage only remains three air intake (first air intake 8, second air intake 9, third air intake 10 promptly), has got rid of independent inlet air channel of compressed air and complete machine hot-air outlet.
