Description
Technical field
The present invention relates to communication facilities, particularly, relate to a kind of cooling control system, method and apparatus, be applied to be arranged in the communication facilities of communications equipment room.
Background technology
In traditional communications equipment room environment such as data center machine room, in order to reduce the energy consumption of machine room, adopt unified air channel to carry out cooling.Rack is arranged line by line side by side in communications equipment room, and the rack of being arranged line by line in the machine room space is separated.Cold wind enters from a side of rack, through behind the communication facilities of interior of equipment cabinet, goes out from an other effluent, thereby takes away the heat of communication facilities.The zone that provides cold wind to enter for communication facilities between the two adjacent row racks is called the cold-zone, and air-out and a side of taking away heat are called as the hot-zone between the two adjacent row racks.Particularly, the air-conditioning system of machine room self is sent cold wind into the cold-zone, behind the communication facilities in the cold wind process rack, is taken away by the ventilation equipment of machine room in the hot-zone.Cold wind the path of process form the air channel of machine room.
According to the air channel layout characteristics of different communication machine room, the hot-zone in the different machine rooms and the direction of cold-zone may be just the opposite.This is for fixing equipment cabinets and chassis, requirement is installed in the design that its inner communication facilities need to be supported vertical heat dissipation path and heat dissipation path from back to front, wherein, before refer to business board for the user provide port or operation a side, be the front side of business board, after refer on the business board with respect to the front side opposite side, be the rear side of business board, and fan is arranged on the rear side of business board usually.
