Said fans module of the present utility model is characterized in that: the described fan power supply line that is provided with on the described housing rear board, the jack of control line socket are asymmetrical shape up and down.
In telecommunications equipment cabinet, use blower module of the present utility model, have following technique effect:
The first, utilize the big characteristics of centrifugal fan blast, can overcome bigger windage.A centrifugal fan is installed in the following cofferdam under the horizontal division board of blower module, to extract out by force from the rack lower bigger thermal current of windage, bottom air inlet by blower module enters centrifugal fan, utilize this fan to be the characteristics of 90 degree output gas flows again, the thermal current that enters fan is discharged rack by the exhaust outlet of blower module rear board.An aerofoil fan or centrifugal fan are installed in the cofferdam on horizontal division board, will be from the thermal current suction blower module inside at blower module top, by stopping of central dividing plate, make this part thermal current discharge rack from the exhaust outlet of blower module rear board.
The second, by the horizontal division board in centre position in the housing, a plurality of fans are installed in the blower module, reduced the volume of blower module, reduced the volume of whole communication cabinet simultaneously.
The 3rd, the power line of power line, control line and the aerofoil fan of centrifugal fan in the blower module is made in the socket, this socket head is fixed on the blower module rear board, during the mounting or dismounting blower module, by being connected and fractionation of plug and socket, realize the blind plug and the hot plug of blower module.
The 4th, pivoting handle is installed on the front panel of blower module, when the installation or removal blower module, handle is spun out, be convenient to operation; When installation or removal finished, parallel being placed on the housing front panel of will shaking hands made handle not take enclosure interior.
