Description
Technical Field
The invention belongs to the technical fields of temperature control, heat dissipation, uniform airflow and the like, and particularly relates to a tower-type porous air supply temperature control device for a data machine room.
Background
With the development of IT devices, data processing and storage capabilities are rapidly increasing, and recent applications such as cloud computing, Artificial Intelligence (AI), and internet of things (IoT) are changing our lives in all respects. A data room is a room that houses a large number of IT devices (e.g., servers, data storage and communication equipment, network equipment, and power supplies) that are arranged in columns in computer racks and cabinets to reduce the floor space required. Statistically, the data room in the united states consumes 1.8% of the total power in the united states (about 700 billion kilowatt-hours), and energy consumption is expected to surge to about 1400 billion kilowatt-hours by the year 2020. Among the energy consumed by the data room, the cooling system may exceed half of the total energy consumption and account for a major portion of the total operating costs. In this respect, it is imperative to reduce the energy consumption of cooling systems in terms of sustainable development of data rooms.
Currently, for the flow management of a data room, a cooling system of the data room may be classified as a long-distance cooling system or a short-distance cooling system according to an airflow path used. Major problems in airflow management include hot air recirculation, cold air bypass, leakage, supply air distribution, and airflow/temperature non-uniformity, among others. For long distance cooling systems, airflow management typically employs an overhead configuration and hot/cold aisle containment arrangement, and for short distance cooling systems, server layout and heat exchanger layout are primarily considered in relation to airflow uniformity.
The long-distance cooling system is widely applied to the market, but has the defects of large floor area, large air supply quantity, high energy consumption and the like, so that more researches are promoted to be turned to the short-distance cooling system. The main short-distance cooling systems at present are: the patent provides a tower-type porous air supply temperature control device of a data machine room aiming at the problems.
Due to the above-mentioned disadvantages of the long-distance cooling system, and all the devices in the data room are in an open arrangement, the air quality requirement is high, and when the content of particulate matters in the air is high, the possibility of scaling on heat-generating devices such as servers and storages increases, thereby causing continuous deterioration of heat exchange. More and more data rooms have thus started to employ short-distance cooling systems, where more rack-mounted cooling systems with heat exchangers are used, which systems essentially have: a fan installed at the rear side of the server; and the heat exchanger is arranged at the bottom of the rack. Meanwhile, the cold and hot channels are well isolated, and air recirculation and cold air bypass are avoided. But the existence of the heat exchanger can affect the duty ratio of the data room, thereby causing the reduction of space utilization rate.
In recent years, heat pipe technology is increasingly utilized in data room cooling systems due to its passive nature and fast response function. The heat pipe cooling system is developed quickly because no moving part is used for heat exchange and the heat exchange working medium can be properly adjusted along with the working condition. However, the heat pipe structure is relatively complex, and the heat exchange performance is greatly affected by the heat exchange working medium, so that complex structural design and a large amount of working medium screening work need to be performed in the system design process.
