Too high temperature in the server cabinet is a common problem in the data center. It is not uncommon for the server to go down because of too high temperature in the server. Some organizations have made statistics on the causes of server downtime in the data center, and found that in addition to the failure of the server itself, the other two main causes are too high ambient temperature (32%) and power failure (22%). There are two reasons for the high temperature in the cabinet
First, due to the increasing number of servers, the space in the data center is becoming more and more tight, and more and more servers have to be placed in the cabinet. Moreover, the current development direction of computer is smaller and smaller, more and more compact, especially the emergence of blade server, which leads to the temperature in the data center cabinet far beyond the range that the computer and other equipment can bear.
Another reason is that the current server ventilation mostly adopts forward and backward ventilation (while the traditional server ventilation adopts downward and upward ventilation), but these cabinets are still placed in rows like desks in the classroom. The hot air from the front is transferred to the cabinets in the back, and the mixing of cold and hot air is unreasonable. In order to solve the problem of heat management in Telecom room, communication base station and equipment cabinet, there are many commonly used temperature control methods, such as cabinet air conditioner series, heat exchanger series, cabinet air conditioner series integrated with heat exchanger, air conditioning door control box series, digital variable multi technology air conditioning system, liquid cooling system, underground coupled heat pump series and so on.
1、 Cabinet air conditioner series
The traditional room air conditioning seldom considers the temperature inside the cabinet, which can only ensure that the temperature in the room meets the requirements. But in fact, due to the use of blade server, local hot spots are easy to appear in the cabinet. In this regard, the traditional air conditioning can only be solved by further reducing the temperature of the machine room, which will inevitably lead to waste. Cabinet air conditioning can achieve heat absorption and cooling through compression refrigeration,

( 2) Outdoor embedded cabinet air conditioner
characteristic:
● Simple appearance, perfect process, unique embedded structure, no need to add communication cabinet square warehouse, save space, reduce cost, and have good windproof, rainproof, anti-theft function;
● With special heat exchanger, the heat exchange is increased by 40%, the wind resistance is reduced by 50%, and the overall structure is solid, anti dust, anti oil and anti-corrosion;
● Using cooling medium without fckw (Freon), environmental protection, energy saving and high efficiency;
● Exquisite patent fast installation fixed structure, the installation process is simple and fast;
● The remote automatic intelligent monitoring system can monitor and control the temperature control information of the cabinet online and interactively at any time;
● The higher protection level (up to the internal IP55 and external ip34 requirements of the national standard) improves the safety and reliability of the cabinet
Concept: The heat exchanger is a kind of device that uses the air outside the cabinet which is lower than the temperature inside the cabinet to exchange effectively through the heat exchange core to realize the temperature adjustment, so as to meet the heat dissipation requirements of the control cabinet in the closed state, and avoid the high pollution of fresh air.
● The unique high efficiency parallel flow heat exchange core has superior heat exchange efficiency.
● Closed circulation cooling system design, internal and external air isolation, effective isolation of external air pollution sources.
● There is no condensation inside the cabinet due to supercooling.
● The core cold control components are selected from international famous brands, which improves the reliability of the unit and ensures the effect of low noise.
● Free and flexible installation mode: the size of the unit is different, the installation mode is diverse, one machine is multi-purpose, can be wall mounted, embedded, overhead.
● Compact and lightweight, no filter screen design, low cost, no need for regular maintenance.
● The products have passed CE certification and meet the requirements of EU ROHS directive.
