Description
Technical field
The present invention relates to data center machine room environment controlling technique field, and in particular to one kind can be realized to CPU simultaneously
The system that chip and server are radiated.
Background technology
The development of data center of China is swift and violent, and total amount is more than 400,000, and year, power consumption was more than Analyzing Total Electricity Consumption
1.5%, it is contemplated that consumption of data center will be equivalent to the pipe of reinforced concrete at Three Gorges Power Station generated energy of 1 year every year, wherein most of data centers
PUE is still generally more than 2.2, there is larger gap compared with international most advanced level.Data center's information technoloy equipment needs round-the-clock progress cold
But, freezed in usual computer room using precision air conditioner, so as to ensure the environmental Kuznets Curves requirement of data center.Data center's air-conditioning
Unit power consumption has accounted for the 35%-45% that computer room always consumes energy, and is only second to the energy consumption of data center's information technoloy equipment, causes data center
PUE values are higher, and efficiency utilization rate is low.During actual motion, the main heat sink part in server is central processor CPU, and it dissipates
Heat accounts for the 80% of the total heat dissipation capacity of server, and the existing type of cooling of data center is usually first cooler environment cools down set again
It is standby, such as GB50174-2008《Electronic information system machine rooms design specification》Described in A, B class computer room require 23 DEG C ± 1 of environment temperature
DEG C, because the heat generating spot in computer room is not to be evenly arranged in computer room, but in main concentration and equipment and chip, tradition
The type of cooling can only cause environment temperature drop in computer room, and temperature of the equipment with chip in itself does not decline or declined
Speed it is too slow, be also unable to catch up with equipment and chip heating programming rate, cause energy loss and do not reach cooling effect, make
It is high into hot localised points temperature, PUE is not reduced.
The content of the invention
The technical problems to be solved by the invention are that existing type of cooling consumption mass energy does not but reduce equipment in itself
With the temperature of chip, cooling effect is poor, and its object is to provide one kind to dissipate cpu chip and server while realizing
Natural cooling source is combined by the system of heat, the system with cooling by wind cooling technology, using the heat pipe heat radiation close to thermal source
Device is cooled down to server, is reasonably organized by air-flow, utilizes service-oriented device and the Cooling Solution of chip-scale, one
Aspect can effectively reduce PUE, improve efficiency utilization rate, on the other hand can effectively solve due to precision air conditioner unit air current composition not
The problems such as rationally causing hot localised points；Computer room space availability ratio is effectively improved simultaneously, more racks and server can be arranged, so that
Economic benefit and the effect saved land can be effectively improved.
The present invention is achieved through the following technical solutions：
It is a kind of to realize the system radiated to cpu chip and server, including outdoor natural cooling unit simultaneously
