Description
Technical field
The present invention relates to server cabinet, and in particular to a kind of data center server cooling that can realize transmission of heat by contact
Rack.
Background technology
With the raising of server integrated level, the power of data center machine room single chassis is substantially improved.Data center is at a high speed
The characteristics of development and its high energy consumption, by society's highest attention, carries out reducing energy consumption or builds the data center pair of high energy efficiency to which
It is significant in energy-saving work.According to statistics, now newest blade server frame power is up to 15kW, platform
Formula server rack power is 1.5kW, and modular server rack power is 5kW.High power consumption necessarily leads to high heating, and this causes
Local pyrexia becomes very serious, and thermograde changes greatly, aeration-cooling to process complicated.The shutdown of air-conditioning short time or refrigerating capacity are not
Foot, computer room temperature can quickly rise to limiting temperature, cause server all to report to the police and even shut down.Show according to related data, I
There is machine phenomenon of delaying in state-owned nearly 33% machine room Zeng Yinwei air conditioner refrigerating problems.The computer of highly energy-consuming is absorbed in data center
Predicament.
The radiating of server is the focus of industry forever, is calculating density more and more higher, and power consumption is increasing
Today, server especially widely apply the data center of server, and heat dissipation problem is eternal " that what is waved does not dissipate ", now, due to outer
Portion's radiating is difficult to be fully solved problem, and radiating efficiency is relatively low, often results in server internal hot-spot, so as to reach
To the requirement of server radiating, then more and more manufacturer server focuses on the radiating of server in server
Portion.For server radiating, especially internal heat dissipating, simple increase number of fans or increase rotation speed of the fan can not be very
Good solve problem, fan are more, and rotating speed is faster, and power consumption is also more, and noise also can be bigger, for a user, power consumption and
Noise is also very big problem.
Therefore find a kind of how under the premise of limited space and air-conditioning input, ensure effective radiating effect, with reality
The quantity of existing rack is maximized and the maximized heat abstractor of quantity of rack server is compeled in eyelashes.
The content of the invention
It is an object of the invention to solve existing service device heat dissipation problem, and provide a kind of number that can realize transmission of heat by contact
