Description

Box-type data center adopting top-mounted air conditioner module

Technical Field

The utility model belongs to the technical field of data center technique and specifically relates to a low cost, standardization, modularization, be convenient for dispose fast and the on-the-spot quick installation adopt top mounted air conditioning module's box data center.

Background

Modern society is increasingly dependent on data and networks, which have become an integral part of our daily lives, as have air, water, electricity, gas, etc. Cloud computing, internet of things, edge computing and the like, and all mass general data and information can not be stored and processed in a data center.

The data center of traditional civil engineering computer lab formula has planning construction cycle length, construction cost height, electric energy utilization rate low grade inadequately, and following several reasons make the data center of traditional civil engineering formula can't satisfy current needs:

1) the east cities with developed economy have high land cost and short energy supply, and the construction of data centers in the crowded east cities brings high operation cost, so that the data centers are constructed in the energy main producing areas in China and the western areas with rare population, and the construction cost and the operation cost of the data centers can be greatly reduced. And if the data center is further built in an open field, a large amount of environmental low-temperature resources, solar energy and wind energy can be utilized, and the operating cost is further reduced. However, large-scale civil works are carried out in places far from cities, which is high in labor cost and may damage the natural environment.

2) The new generation of technology appears in the electronic field about every 3-5 years, the traditional data center construction mode needs 1-2 years of time for planning and construction, and after the data center construction is completed, the advanced technology is already in the middle of the technical life when the data center is initially designed and planned.

3) And open global economic cooperation, so that the circulation of resources, technologies and goods is more intimate, and under the background, countries with electronic information technology and industrial advantages can help countries with weak infrastructure to build data centers and communication facilities locally through the output of the technology and equipment so as to eliminate the poverty of developing countries and improve the informatization level. In remote foreign countries and other countries, the data center is built in a mode of building a bridge by using a traditional house cover, and the building cost and the building period can not meet the requirements far away.

4) And sudden natural disasters or events may cause paralysis of communication traffic and information transmission in the disaster area, and a means for rapidly recovering the communication and information transmission in the disaster area in a short time is needed.

5) The expansion of services and the provision of power with a certain margin for existing data centers that have already been built and put into operation makes it possible to expand existing services with the use of the surplus power provision potential.

Some existing types of box container data centers have the following disadvantages or shortcomings: 1) in the existing box-type data center, the air-conditioning and refrigerating units are divided into indoor units and outdoor units, wherein the indoor units are installed in an IT equipment cabin, and the outdoor units are installed at other places except the IT equipment cabin, so that the air-conditioning indoor units and the air-conditioning outdoor units which are respectively positioned inside and outside the IT equipment cabin are required to be subjected to refrigerating pipeline and electrical connection on the installation and use site of the equipment, the workload of site installation is increased, and the site construction and installation time of the data center is prolonged; 2) due to the existence of the connecting pipeline between the air conditioning indoor unit and the outdoor unit, the pipeline installed on site may have potential installation defects due to the detection condition of the site installation or the lack of the operation skill of an installer, which results in the reduction of the reliability of the data center; 3) the air-conditioning indoor unit arranged in the IT equipment cabin occupies part of the cabin space, so that the number of the mountable IT equipment is reduced, the aim of high-density deployment cannot be achieved, the number of the IT cabinets needs to be increased for deploying the same number of IT equipment, and investment is increased and the electric energy utilization rate is reduced; 4) because the indoor air conditioning unit in the IT equipment cabin has different air supply distances from each IT equipment cabinet row, the temperature in the IT equipment cabin is uneven, and particularly under the condition of high-density deployment, local overheating is easily generated, so that the reliability and normal operation of the IT equipment are influenced; 5) because the air conditioning indoor unit is installed in the IT equipment cabin, maintenance personnel need get into the IT equipment box and just can maintain or safeguard the air conditioning indoor unit, can bring adverse effect to data center's security like this.

In view of the foregoing, there is a need for a low-cost data center that can be quickly deployed in a minimum amount of time.
