CDU cold quantity distributes unit: CDU cold quantity distributes unit the action principle in liquid cooling system
As the development of science and technology, the issue of specific power consumption of data center is increasingly outstanding, liquid cooling system becomes data center to come loose gradually because of its efficient, energy-saving character hot plan. In liquid cooling system, CDU cold quantity allocates unit to acting crucial role. The article discusses development CDU cold quantity to distribute unit the action principle in liquid cooling system, offer value to elaborate for company level client.
One, CDU cold quantity allocates unit overview
CDU (Cooling Distribution Unit) namely cold quantity distributes unit, it is one of component of the core in liquid cooling system. The main function of CDU is will cold fluid carries server machine ark, implementation comes loose to the server hot crucial link. CDU is main wait for composition by pump, heat exchanger, filter, flowmeter.
2, CDU cold quantity distributes unit the action in liquid cooling system
1.Rise medicinal powder thermal efficiency
CDU cold quantity allocates unit to having crucial effect in liquid cooling system, through carrying cooling fluid server machine ark, take away the quantity of heat that the server produces, implementation is efficient medicinal powder hot. As cold as traditional wind medicinal powder hot means photograph is compared, liquid cooling comes loose heat is had taller medicinal powder thermal efficiency, can drop data center temperature effectively, raise equipment to run stability.
2.Energy-saving decrease a platoon
Liquid cooling system has inferior specific power consumption, CDU cold quantity allocates unit to be in in carrying cooling fluid process, reduced waste of the sources of energy. In addition, CDU has self-adjusting function, run requirement actually according to the server, reasonable allocation cold quantity, reduce specific power consumption further.
3.Prolong equipment life
CDU cold quantity allocates unit to be in liquid cooling system, made sure the server comes loose hot effect, reduced a server to run temperature, prevented the equipment breakdown that causes because of overheat effectively. In the meantime, of CDU filter the function can enter cooling fluid with preventing dirt, impurity, lower equipment fault rate, lengthen service life of equipment.
4.Adaptability is strong
CDU cold quantity distributes unit but according to demand of different aircraft ark, adjust cold quantity to allocate neatly. Below circumstance of deploy of high temperature, high density, CDU can make sure the server comes loose hot effect, raise data center to run stability.
3, CDU cold quantity allocates unit job principle
1.Cold fluid preparation
CDU cold quantity allocates unit to carry cooling fluid refrigeration equipment above all, wait like cold water aircrew, hot pump, undertake cooling handling. The liquid after refrigeration can return CDU with inferior temperature.
2.Cold fluid allocates
Cooling fluid passes the pumping station of CDU, be carried to come each server machine ark. CDU carries the equipment such as flowmeter, run requirement actually according to the server, reasonable allocation cold quantity.
3.Medicinal powder hot
Cooling fluid flows in interior of server machine cabinet, take away the quantity of heat that the server produces, implementation is efficient medicinal powder hot.
4.Cold fluid reclaims
Medicinal powder the cooling fluid after heat returns CDU, after filtering through filter, be remanded again refrigeration equipment undertakes cooling handling, form to close circularly.
4, summary
CDU cold quantity allocates unit to producing crucial effect in liquid cooling system. It rose to come loose not only thermal efficiency, reduced specific power consumption, still prolonged equipment life, raised data center to run stability. To company level client, understanding CDU cold quantity allocates unit action principle, conduce to optimize data center to come loose better hot plan, enhance company competition ability.
In liquid cooling system increasingly all-pervading today, the value that CDU cold quantity assigns unit is self-evident. Allocate the thorough knowledge of unit action principle through cold to CDU quantity, company level client can hold liquid cooling technology to develop a tendency better, for the enterprise development lays solid foundation.
