Application of liquid cooling technology to reduce the heat generated in the electronic products is very extensive, including game consoles, super computer and medical equipment. But in today's data center industry in the most popular technology, server manufacturers began to turn to the liquid cooling technology, to achieve economic and effective thermal management. Especially fast connector has played an indispensable role in the performance and reliability of the cooling system.
For a long time, the formation of security cooling system is economical and effective to remove the heat, the data center is an increasingly serious problem. Over the past ten years, due to the increased power density server rack server, the energy consumption is also rising sharply. Ten years ago, the power consumption of a single server rack is 250W to 1.5kW, now the power consumption is about 10 kW frame. Over the next ten years, the power consumption is expected to reach 50kW. Moreover, it is estimated that in 2020, the data center industry generated CO2 will be flat with the amount of the aviation industry.
In the traditional sense, the data center uses the air to heat. However, the low efficiency and high cost of the air conditioner through the server support to eliminate the heat. Sixty percent of the cooling air is lost due to bypass and air mixing, and cooling costs may be higher than the cost of running the server. With the speed of the operation of the computer server and the rise of the density of the data center rack, the idea that through the air circulation to achieve the full cooling is not realistic.
On the other hand, from the point of view of quantity, water storage and heat transfer efficiency is 3500 times higher than the air. In fact, in a recent survey of a variety of industries, 41% of respondents believe that the combination of air and liquid cooling of the cooling method of the primary data center. The liquid cooling is to improve the cooling efficiency and reduce the cost of the air conditioner of the best choice.
The use of computer cooling liquid can be traced back to the mid 60's, at that time, IBM (IBM) implementation of the liquid cooling on the 704 host. After almost 50 years. Recently, IBM for a Swiss university for a supercomputer used the processor level liquid cooling technology, through the circulating water to cool the processor and then pump it to the floor heating system, so that waste heat can be used for heating. According to IBM estimates, compared with the air cooling liquid cooling system server, energy consumption is 40% less than the former, and the waste heat is reduced about 85% of the carbon footprint.
