Two-phase is cold board type liquid cooling: Two-phase is cold photograph of board type liquid cooling changes conduct heat with efficient medicinal powder hot mechanism
One, foreword
As the ceaseless development of electronic technology, the demand that server and data center heat up a technology to coming loose is higher and higher. Two-phase is cold technology of board type liquid cooling serves as a kind efficient, energy-saving medicinal powder hot means, make the central point that the industry pays close attention to gradually. Article general from two-phase cold photograph of board type liquid cooling changes conduct heat with efficient medicinal powder two respects undertake hot mechanism be analysed deep, with period come loose for our country the development of hot technology provides reference.
2, two-phase is cold photograph of board type liquid cooling changes spread hot mechanism
1.Change conduct heat principle
Two-phase is cold liquid cooling technology used board type to change conduct heat principle. When cold intermediary (wait like glycol, acetone) from liquid state change is gaseous state, its temperature can be reduced; Conversely, when change of gaseous state cold intermediary is liquid state, its temperature will be elevatory. In this process, cold intermediary can be absorbed or release a large number of quantity of heat, come true to come loose efficiently thereby hot.
2.Two-phase is cold structure of board type liquid cooling
Two-phase is cold system of board type liquid cooling is main by cold board, the composition such as cold intermediary, water pump, radiator and control unit. Cold board be located in electronic equipment surface, deliver quantity of heat cold intermediary; Cold intermediary carries radiator through water pump, undertake changing in radiator, deliver quantity of heat the environment; Control the moving state of unit and responsible supervisory system, assure to come loose hot effect.
3, two-phase is cold board type liquid cooling is efficient medicinal powder heat engine manages
1.Large specific heat capacity
Cold intermediary is changing larger specific heat capacity is had in the process, this makes when cold intermediary is being absorbed or releasing quantity of heat, temperature change is minor. Accordingly, two-phase is cold technology of board type liquid cooling is had taller medicinal powder heat energy force.
2.Force to circulate
The cold intermediary flow in the system comes true through water pump, this kind forces to be able to raise the rate of going from place to place of cold intermediary circularly, rise thereby medicinal powder thermal efficiency.
3.Better cool performance
Two-phase is cold technology of board type liquid cooling has better cool performance, the wind that its refrigeration efficiency compares a tradition is cold medicinal powder hot technology is high. In addition, liquid cooling technology still can reduce the temperature wave motion of equipment, assure electronic equipment to move below stable temperature environment.
4, two-phase is cold the advantage of technology of board type liquid cooling
1.Efficient and energy-saving
Two-phase is cold liquid cooling technology has board type to come loose efficiently heat energy force, can satisfy the requirement with server and data hot to coming loose center. In the meantime, liquid cooling technology dropped the temperature of equipment, improved the moving efficiency of equipment.
2.On the safe side
Two-phase is cold technology of board type liquid cooling has better cool performance, can prevent electronic equipment overheat effectively. In addition, cold intermediary has taller insulation property, reduced the risk of electric fire.
3.Green environmental protection
Liquid cooling technology can reduce the heat of data center to discharge, reduce the sources of energy to use up, accord with our country energy-saving the demand that reduces a platoon.
5, summary
Two-phase is cold technology of board type liquid cooling is running conduct heat with efficient medicinal powder hot mechanism respect has distinct advantage, it is our country comes loose the important way that hot technology develops. As the ceaseless maturity of relevant technology, two-phase is cold hopeful of technology of board type liquid cooling gets applied extensively in the domain such as data center, server.
The article around two-phase cold technology of board type liquid cooling undertook thorough analysis, aim to come loose for our country the development of hot technology is offerred draw lessons from benignantly. In future, two-phase is cold technology of board type liquid cooling comes loose hopeful for equipment of our country electron hot field brings more innovation gain.
