Cabinet cooling technology in general
Cabinet cooling technology in general
With the rapid development of communication equipment, as Moore's law predicted, the heat dissipation of the telecom room density growth significantly. With the blade
To use, high density cabinet can reach more than 20 kW of power, the load more than general room thermal capacity. Have high energy consumption, local overheating
Is common problem nowadays equipment room. The cabinet in itself in the face of heat dissipation by the designer has the process?
The design of the cabinet cooling process is mainly in the following aspects:
Use fans forced ventilation cooling;
Side panel and door mesh design, hole rate above 50%;
Design special cabling channel, not hot and cold air duct partition; Stop by a blind plate hot air reflow, cabinet form good cold and hot wind channel;
The commonly used way to circulate in cabinet
One way to circulate in cabinets,
From the bottom of the cabinet of the side into the cold wind, after equipment,
Drain the hot air from the upper cabinets, hot air through hot air into the ceiling;
The other is a cabinet outside circulation way,
On the floor in front of the cabinet or back set ventilation shutters, cold wind from the shutter out of and into the cabinet,
Hot air from the top cabinet front and back or to send out, hot air into the ceiling.
Two cycle modes can be combined with use, the effect is better.
