The demand that wind pressure is promoted simultaneously.
In the prior art, many heating and ventilating equipments are required for multi-panel outlet air, to accelerate heat exchange.And wind in the prior art
Machine system is single side outlet air mostly, cannot be satisfied the requirement of multi-panel outlet air.
It is mutual dry due to space limitations and between adjacent fan blade when more typhoon leaf parallel runnings of the prior art
It disturbs so that fan efficiency is relatively low, and noise is higher.
In view of above-mentioned background, the present invention proposes a kind of multiple duct centrifugal blower, with solve prior art airflow pressure it is less than normal,
It can not multi-panel outlet air, the technical problem that multiple fan blade parallel fan efficiency is low, fan noise is big.
Invention content
The present invention solve above-mentioned technical problem technical solution be：
A kind of multiple duct centrifugal blower, including shell, centrifugation blade, motor.
Further, the enclosure interior is equipped with partition board, and shell is separated into two or more air ducts, and adjacent two
A air duct is connected to, and there are one centrifugation blade and a motors in each air duct.
Further, one or more air outlets are provided on the shell, the position of air outlet and quantity can bases
Application space feature is configured.
Further, the partition board can be single layer structure or double-layer structure.
Further, the double-layer structure of the partition board is made of internal layer partition board and outer layer partition board, and internal layer partition board is close to centrifugation
Fan blade, outer layer partition board is far from centrifugation blade.
Further, the internal layer partition board is equipped with a certain number of holes.
Further, the double-layer structure of the partition board, there are gaps between internal layer partition board and outer layer partition board.
For the prior art, the advantageous effect of multiple duct centrifugal blower of the present invention is：
（1）Multiple duct centrifugal blower of the present invention, combines fans in series and advantage used in parallel, can improve multiple
Air quantity when centrifugation blade cooperation and wind pressure；
（2）Space availability ratio when multiple wind turbine cooperations, and outlet air can be improved in multiple duct centrifugal blower of the present invention
The number and position of mouth can be flexibly arranged according to the characteristics of application space, realize single side or multi-panel outlet air；
（3）The double-layer structure of partition board of the present invention can play the role of reducing fan noise, wind turbine low noise is made to run,
Better than other serial or parallel connection centrifugal blowers.
