We need to design a kind of ventilation shaft of connection wind turbine, lower the noise generated in air-flow flow process, reduce wind speed, improve
Passenger takes the comfort level of car.
Utility model content
The purpose of this utility model is to provide for a kind of coach air conditioner evaporation fan, the evaporation fan reasonable design,
It is easy for installation, coordinated by the vent passages being connected, can effectively reduce the noise generated in the evaporation fan course of work, subtract
Small wind speed improves occupant comfort sense, while effectively reducing evaporation fan energy consumption by frequency conversion function, reduces operating cost, assembly
Single charge driving range can be effectively increased on pure electric coach.
In order to achieve the above object, the utility model provides following technical solution：A kind of coach air conditioner evaporation fan,
Including motor, it is set to the centrifugal blower at motor both ends, the motor is equipped with frequency converter, the centrifugal blower connection
Air-out passage, the motor and centrifugal blower are evaporated in 30 ° of inclined are installed on shell, and the air-out passage includes first
Straight channel, the second straight channel and connection the first straight channel, the second straight channel arc-shaped channel, first straight channel connect from
The air outlet of heart wind turbine, and parallel with the air-out direction of air outlet, the corresponding central angle in the arc-shaped channel is 30 °, institute
The silencer wall that is internally provided with for stating air-out passage is equipped with heat dissipation channel between the silencer wall and the inner wall of air-out passage, described to disappear
The outer wall of sound wall is equipped with acoustical cotton, and the shell of the centrifugal blower is equipped with sound absorbing layer.
It is further preferred that the acoustical cotton is using wedge-shaped acoustical cotton.
It is further preferred that the acoustical cotton is tightly attached to by binder on the outer wall of silencer wall.
The ventilation for being axially spacedly distributed, and circumferentially extending along silencer wall it is further preferred that the silencer wall is equipped with
Hole.
It is further preferred that the acoustical cotton is equipped with the lug boss to match with venthole.
It is further preferred that the motor both ends are equipped with several heat emission holes.
The beneficial effects of the utility model：The evaporation fan reasonable design, it is easy for installation, pass through the vent passages being connected
Cooperation can effectively reduce the noise generated in the evaporation fan course of work, reduce wind speed, improve occupant comfort sense, lead to simultaneously
Crossing frequency conversion function effectively reduces evaporation fan energy consumption, improves coach air conditioner working efficiency, reduces operating cost, is assemblied in pure electric vehicle
Single charge driving range can be effectively increased on car.

Specific implementation mode
We make further a kind of coach air conditioner described in the utility model of evaporation fan in conjunction with attached drawing below
It is bright.
As shown in Figures 1 and 2, a kind of coach air conditioner evaporation fan of the present embodiment, including motor 1, be set to
The centrifugal blower 2 at 1 both ends of motor, the motor 1 are equipped with frequency converter 11, and the centrifugal blower 2 connects air-out passage 3,
The motor 1 and centrifugal blower 2 are evaporated in 30 ° of inclined are installed on shell 4, and the air-out passage 3 includes first straight-through
The arc-shaped channel 33 of the first straight channel 31 of road 31, the second straight channel 32 and connection, the second straight channel 32, first straight channel
The air outlet 21 of 31 connection centrifugal blowers 2, and it is parallel with the air-out direction of air outlet 21, the arc-shaped channel 33 is corresponding
Central angle is 30 °, and the air-out passage 3 is internally provided with silencer wall 5, is set between the silencer wall 5 and the inner wall of air-out passage 3
There are heat dissipation channel 6, the outer wall of the silencer wall 5 to be equipped with acoustical cotton 7, the shell of the centrifugal blower 2 is equipped with sound absorbing layer 21.
By acoustical cotton, the cooperation in arc-shaped channel and silencer wall, noise is effectively reduced, while slowing down air-flow wind speed.Pass through heat dissipation
The setting in channel avoids air-out passage outside wall temperature excessively high, influences coach air conditioner refrigeration effect.
In the present embodiment, the acoustical cotton 7 is using wedge-shaped acoustical cotton.The acoustical cotton 7 is tightly attached to noise reduction by binder
On the outer wall of wall 5.The silencer wall 5 is equipped with along the axial venthole 51 for being spacedly distributed, and circumferentially extending of silencer wall 5.Institute
It states acoustical cotton 7 and is equipped with the lug boss 71 to match with venthole 51.In the case where not influencing air-flow flowing, to greatest extent
Improve erasure effect.
In the present embodiment, 1 both ends of the motor are equipped with several heat emission holes 12.Ensure motor work steady in a long-term
Make.
The scope of protection of the utility model is not limited to above example and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
