It is preferred that, it is evenly distributed with radiating fin in the hollow sandwich.
Seen from the above description, the frequency conversion smoke exhaust fan that the utility model is provided is when occurring fire alarm, while by air-cooled
And water-cooling, it is thus possible to good cooling effect is provided for motor, it is ensured that smoke exhaust fan steady operation at high operating temperatures.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model mixed cooling smoke exhaust fan.
Fig. 2 is the internal structure schematic diagram of the utility model mixed cooling smoke exhaust fan.
Fig. 3 is the vertical view cutaway drawing of the utility model mixed cooling smoke exhaust fan.
Fig. 4 is the side view cutaway drawing of the utility model mixed cooling smoke exhaust fan.
Embodiment
Below by way of embodiment, the utility model will be further described.
As shown in Figures 1 to 4, the mixed cooling smoke exhaust fan includes airduct 1, is arranged at the smoke evacuation of airduct air outlet
Impeller 2, motor casing 3, motor 4 and the heat-dissipating impeller 5 for being set up in the center of airduct 1, motor 4 and heat-dissipating impeller 5 are arranged at motor casing 3
It is interior, there is output end before and after the motor shaft of the motor 4, the motor shaft front end of motor 4 extends to that motor casing 3 is outer, motor shaft end
End is located in motor casing 3, and smoke evacuation impeller 2 is connected with the front end of motor shaft, and heat-dissipating impeller 5 is connected with motor the tip of the axis, motor
Shell 3, which is provided with to be evenly distributed with radiating fin, motor casing 3 in hollow sandwich 31, hollow sandwich 31, is communicated with hollow sandwich
31 water inlet 32 and delivery port 33, water inlet 32 is communicated with inlet channel 34, and delivery port 33 is communicated with outlet conduit 35, water inlet
Pipeline 34 and outlet conduit 35 are connected with fire-fighting waterway, and inlet channel 34 and outlet conduit 35 are made up of stainless steel, motor
Air inlet 37 and air outlet 38 inside motor casing 3 are communicated with shell 3, the air inlet 37 is arranged on motor casing 3 close to row
Intake stack 39 is communicated with the front end of tobacco leaf wheel 2, air inlet 37, the other end of the intake stack 39 is extended to outside airduct 1, is gone out
Air port 38 is arranged in the end of motor casing 3, the connection power supply of motor 4, the present embodiment, and inlet channel 34 is provided with magnetic valve 36,
In other embodiments, magnetic valve 36 can not be set on inlet channel 34.
This mixed cooling smoke exhaust fan can be used as draught fan and be used but also as fire control smoke exhausting fan, as logical
Wind fan is not in use, because the internal temperature of airduct 1 is high, as long as now being imitated by the radiating needed for air-cooled i.e. reachable motor
Really；When occurring fire, because the inside of airduct 1 is full of high-temperature flue gas, now the operating temperature of motor 4 is very high, due to occurring fire
The unlatching of the fire-extinguishing apparatus such as applicator when dangerous, makes the current inside fire-fighting waterway start flowing, and current pass through in motor casing 3
Empty interlayer 31 cools to the inside of motor casing 3, and is rotated positioned at the heat-dissipating impeller 5 of motor shaft end, by outdoor Cryogenic air
Introduced via intake stack 39 inside motor casing 3, airduct 1 is then expelled to by air outlet 38, by water cooling and air-cooled combination,
Reach the radiating good to motor 4, it is ensured that its steady operation.
Some embodiments of the present utility model are above are only, but design concept of the present utility model is not limited to
This, all changes for carrying out unsubstantiality to the utility model using this design all should belong to infringement the utility model protection domain
Behavior.
