Reason ability also gradually increases, but the power consumption of equipment also increases therewith, causes the caloric value of equipment within machine cabinet more.According to system
Meter, equipment cabinet server caloric value is big in domestic large-scale IDC computer rooms at present, and essentially annual 8760h operations, new for not using
For the computer room of wind, whole year is both needed to cooling, causes air conditioning energy consumption huge, and its air conditioning energy consumption accounts for data center module entirety energy consumption
Traditional data computer room air supply mode has the air-supply of bottom plate air channel, the air-supply of cold and hot channel separation and full room refrigeration air-supply etc.
Mode, the pattern have been unsatisfactory for modernizing the refrigeration demand of computer room high density rack, occur that hot-spot, power consumption is big, machine
The problems such as room air conditioning energy consumption is too high, noise is big.Precise machine room air conditioner need to humidify repeatedly simultaneously, dehumidify operating or supporting special dehumidifying
Machine carries out computer room air humidity, dew point control, to ensure that condensation does not occur for device interior, causes computer-room air conditioning system refrigerating efficiency
Reduce, energy consumption increase.If computer room heat dissipation problem solve it is bad, will serious threat calculator room equipment safe operation.Therefore
How in the case where meeting equipment requirement, the energy consumption for effectively reducing air-conditioning system in computer room is air conditioner industry and modem
The major issue that operation industry in room faces.
Consider have directly use the indoor scheme for computer room cooling of outdoor air introducing at present, its is excellent from Energy Angle
Point is high cooling efficiency, initial cost is low, energy consumption is low, but shortcoming is after introducing outdoor cold air so that room air cleanliness factor, wet
Degree is difficult to ensure that, brings potential safety hazard, and later stage operation maintenance amount is larger.Also have in addition using gas gas honeycomb heat exchanger, will
Heat pipe hot-air and outdoor cold air indirect heat exchange, so as to reduce temperature in computer room；Its advantage be using outdoor cold source when not
Outdoor air is introduced, does not influence the cleanliness factor and humidity of the air in computer room, shortcoming is that initial cost is of a relatively high, heat exchanger knot
Structure is more complicated, easily blocks, it is necessary to which periodic cleaning, maintenance workload are big.

Matter is passed directly into the server internal with liquid cooling function, main heater element -- and heat caused by chip (CPU), which is taken away, (to be accounted for
The 70~80% of whole server caloric value), using liquid-cooling heat radiation scheme, dashed forward in theory it is even possible that obtaining unit rack power
Broken more than 50kW/.But current this heat sink conception exists only in Scientific Research in University Laboratory and only a few enterprises small range research, and
One of fail to form applied generalization application, it is important that the reason for, it is its rack because this server using liquid-cooling heat radiation
Built-in liquid cold water distribution system is needed, this just needs to carry out special custom design to liquid-cooled suit business device rack, and rack produces
Producer is usually standardized production, can not be that liquid is cold at this stage also without the key technology for grasping the design of liquid cold water distribution system

Liquid-cooling heat radiation scheme is changed to, no matter whole server cabinets are all replaced as the rack of built-in liquid cold water distribution system
It is that improvement project amount and cost are all very high, has greatly limited to the development popularization of liquid-cooling heat radiation technology.In addition, liquid-cooling heat radiation
System can only take away 70~80% server caloric value, but still the heat for having 20~30% needs auxiliary refrigeration device to hold
Load, more than 50kW high-density applications are up to for liquid-cooled suit business this Single Cabinet power of device, and each rack needs auxiliary cooling
Device handles 10~more than 15kW heat (the 20~30% of general power), if auxiliary refrigeration device still uses traditional wind
Cold radiating mode, easily there is the hot localised points problem of rack, influence the component life of server, this is also that higher density fluid is taken cold
The problem of business device popularization and application can not be ignored.
