It is installed in electric cabinet shell；The inner housing corresponds to and offers the first air outlet, the electricity on the side wall of axial flow blower air outlet
Cabinet shell corresponds to and offers the second air outlet on the side wall of the first air outlet of inner housing；The heat that the frequency converter distributes passes through axis
Flow fan water conservancy diversion, and pass sequentially through the first air outlet and the outflow of the second air outlet.
Further, the inner housing is rectangular case structure；From top to bottom, the axial flow blower and frequency converter are successively pacified
Loaded in inner housing；First air outlet is opened on the roof of inner housing, and second air outlet is opened in electric cabinet shell
Roof on.
Further, further include temperature transmitter for detecting electric cabinet shell body temperature；The temperature transmitter installation
In in electric cabinet shell.
It further, further include the alarm prompted for overtemperature in electric cabinet shell, the alarm is installed on electric cabinet shell
On body.
It further, further include controller for controlling axial flow blower start and stop, the controller is according to temperature transmitter
Detection signal control axial flow blower start and stop.
Compared with prior art, the utility model has the beneficial effects that
(1) frequency converter and axial flow blower are installed in inner housing, and the inner housing forms air exhaust passage, and frequency converter is using
The heat exhaled in the process will not be gathered in electric cabinet shell, thus heat will not be conducted to other electric elements, and compared with
In small space, when axial flow blower operates, air circulation is accelerated, and improves heat dissipation effect；
(2) the utility model reduces the failure rate that frequency converter uses, and extends service life；
(3) temperature transmitter can also understand cabinet temperature in real time, can preset electric cabinet maintenance work, it is ensured that ventilation dissipates
It is hot normal；
(4) according to cabinet temperature automatic start-stop axial flow blower, the service life of axial flow blower is extended, guarantees that ventilation is suitable in cabinet
Freely.
Detailed description of the invention
