Description
Technical field
A kind of convergence control cabinet the present invention relates to cabinet device with insulated ventilation function and using cabinet device.
Background technology
The secondary component switch board of outdoor convergence control cabinet class, its shell are made by the single plate material of metal material at present,
It is characterized in easy to process, weather resistance is good, while metal structure shock resistance is high.But the ventilating system of such cabinet exists
High temperature, high Rizhao Area（Such as Hainan area）Unsatisfactory using showing, its main cause is metal cabinet itself heat conduction effect
Fruit is preferable, and under high temperature, high sunshine condition, space and the electrical equipment being arranged in cabinet in closed cabinet can allow gas in cabinet
The temperature of body raises rapidly；In addition the ventilating system of conventional convergence control cabinet can not change gas in cabinet rapidly, ultimately result in cabinet
Temperature is under high temperature, high sunshine environment, on the contrary far above ambient temperature.
If radiated with the method for improving air exchanging rate, it is necessary to change powerful fan on single-layer metal cabinet
Or multiple ventilation holes are set, two so be present：First, regular maintenance cost can be improved；Second, cabinet can make it that
Protection level it is impacted.In fact, test proves that single-layer metal cabinet, single to change greatly in high temperature, high Rizhao Area
Power fan or the method for setting multiple ventilation holes, its cooling-down effect is also undesirable, and main cause is：High temperature, Gao
Turn into the heater box of a continuous heating by metal cabinet according to environment, while the ventilating system of conventional convergence control cabinet is required for divulging information
Increase filtering material in air-vent, be so just avoided that dust enters cabinet, but these filtering materials are to a certain extent
It is to hinder cabinet ventilation.
