Description
Technical field
The invention provides a kind of liquid cooling rapid-acting coupling flow resistance characteristic method for quick.
Background technology
Along with the development of microelectric technique, the power consumption of chip is more and more higher, and traditional natural heat dissipation and the radiating mode of forced air cooling can not solve the heat dissipation problem of chip.Compared with air, specific heat of liquid wants much higher times, and therefore liquid cooling is the better approach solving the heat radiation of large power dissipating chip.For an electronic equipment, electronic equipment internal has installed the board of many large power consumptions, and each board installs a through liquid cold drawing.A pair liquid cooling rapid-acting coupling installed by the support of through liquid cooled module and electronic equipment, and this joint mainly realizes high-speed communication and the cut-out of liquid coolant.When board inserts on electronic device stand, liquid cooling rapid-acting coupling realizes the connection of liquid coolant, reaches the object to euthermic chip cooling on board.When board takes out from electronic device stand, liquid cooling rapid-acting coupling realizes the cut-out of liquid coolant, is convenient to the leakage that the maintenance of board be there will not be to liquid coolant.
For an electronic equipment, the flow being supplied to its liquid coolant by outside is fixing.The power consumption of electronic equipment internal board is not of uniform size, and therefore the coolant rate of the board needs of different power consumption is also different.Therefore, liquid coolant must be proportionately distributed to each module according to module dissipation, effectively could avoid the appearance of the overheated and supercooling phenomenon of part of module like this.Therefore, board should be all consistent with the flow resistance of liquid cooling rapid-acting coupling, otherwise will affect the flow entering each board liquid coolant.For liquid cooling rapid-acting coupling, just the flow resistance characteristic of joint should test before the mounting, select the joint met the demands.The test of liquid cooling rapid-acting coupling flow resistance generally wants use traffic meter and tensimeter, the flow of liquid cooling rapid-acting coupling internal coolant is entered by adjustment, use testing flow meter flow value, test pressure difference corresponding to this flow with tensimeter, also just obtain the flow resistance characteristic of liquid cooling rapid-acting coupling.
Although existing flow resistance characteristic method of testing measuring accuracy is very high, its efficiency is lower, and step is comparatively loaded down with trivial details.The consistance of liquid cooling rapid-acting coupling flow resistance characteristic to be applied in case radiation technician the most and to pay close attention to, and be not very high to the requirement of measuring accuracy, as long as the error of the flow resistance of liquid cooling rapid-acting coupling and standard flow resistance is in certain error scope, obviously, existing method does not meet the current requirement of technician.
