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.Compare with air, specific heat of liquid is wanted much higher times, so liquid cooling is a better approach that solves large power consumption chip cooling.For an electronic equipment, electronic equipment internal has been installed the board of many large power consumptions, and a through liquid cold drawing is installed on each board.A pair of liquid cooling rapid-acting coupling has been installed on the support of through liquid cooled module and electronic equipment, and this joint is mainly realized quick connection 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 cooling to euthermic chip on board.When board is when electronic device stand takes out, liquid cooling rapid-acting coupling realizes the cut-out of liquid coolant, is convenient to the maintenance of board there will not be the leakage of liquid coolant.
For an electronic equipment, the flow that is offered its liquid coolant by outside is fixed.The power consumption of electronic equipment internal board is not of uniform size, so the coolant rate that the board of different power consumption needs is also different.Therefore, liquid coolant must be pro rata distributed to each module according to module dissipation, could effectively be avoided like this appearance of the overheated and supercooling phenomenon of part of module.Therefore, the flow resistance of board and liquid cooling rapid-acting coupling should be all consistent, otherwise will affect the flow that enters each board liquid coolant.For liquid cooling rapid-acting coupling, flow resistance characteristic that just should joint before installing is tested, and selects the joint meeting the demands.Use traffic meter and tensimeter are generally wanted in the test of liquid cooling rapid-acting coupling flow resistance, by adjustment, enter the flow of liquid cooling rapid-acting coupling internal coolant, use testing flow meter flow value, with tensimeter, test the pressure difference that this flow is corresponding, also just obtain the flow resistance characteristic of liquid cooling rapid-acting coupling.
Although existing flow resistance characteristic test method 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 is to be applied in case radiation technician the most 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.
