Description
Technical field
The present invention relates under a kind of heat pipe integrated preparation technology and interface arrangement, the especially normal temperature, can be to all size heat pipe, it is standby to vacuumize, fill the integration systems such as working medium, sealing.Belong to the heat pipe preparing technical field.
Background technology
In numerous heat transfers and case, heat pipe is known one of the most effective heat transfer element, and it can transmit amount of heat at a distance by its very little sectional area and need not additionaling power.Since the seventies, the hot pipe technique develop rapidly, the scientific research institution of various countries, institution of higher learning, company and factories and miness have been carried out many-sided exploitation, application study, and the hot pipe technique exchange activity of international, area and various countries self is day by day frequent.
Fast development along with electronics and information industry, the electronic component disposal abilities such as central processing unit are strengthened day by day, the heat that produces all increases with it, fin can't satisfy radiating requirements gradually in conjunction with the heat radiation module of fan, especially notebook computer, heat pipe is a quilt be widely used in the conducting heat critical elements of usefulness at present.Heat pipe can be considered and is one and has high heat conducting passive heat transfer element, because inner two phase flow heat passes mechanism, so that the heat-transfer capability of heat pipe is more than hundreds of times of same size copper metal.When utilizing heat pipe as hot transmitter, has reflection rapidly and the little advantage of thermal resistance.Therefore can cooperate the use of heat pipe or its derived product to develop various high-performance heat radiation module, be fit to solve the heat dissipation problem that present various electronic product is derived because of performance boost.
Heat pipe package mainly comprises carbon steel, aluminium and aluminium alloy, copper and copper alloy.Close up mainly by under the high-temperature heating for the sealing of carbon steel heat pipe, spinning closing-in also carries out electric welding soldering and sealing, and it is ripe that equipment and processing technology have been tending towards, but the carbon steel heat pipe has the weak points such as highly energy-consuming, heat transfer efficiency be low, and development approaches stagnates.
And for the heat pipe of the non-carbon steel class materials such as copper, aluminium alloy, because it has extremely low thermal resistance and good heat-transfer character, can be made into high-efficiency heat exchanger, the high efficiente callback middle-low temperature heat is favored by market gradually.
The Cryo Heat Tube material mainly take copper and aluminium matter as main, use comparatively extensive by copper on the market-Water Heat Pipes in general.Although copper-Water Heat Pipes has good heat transfer property, can satisfy the demand of middle Low Temperature Thermal transmission field, for remaining high of domestic and international copper price, its preparation cost has also restricted the development space of copper-Water Heat Pipes.
Heat pipe vacuumize, fill heat transfer medium, also be technique relatively more crucial in the heat pipe preparation process, wherein widely used is the boiling and exhaust method, but this method only is only applicable to the heat pipe specification preparation take water as medium such as copper-water, water steel heat pipe, copper heat-pipe working medium is water, the employing boiling process can solve topping up and vacuumize two key technology difficult problems, seals by the spinning friction-welding technique.And for organic efficient heat transfer medium class heat pipes such as acetone, methyl alcohol, use the method not only to waste medium, and improve production cost, also easy atmosphere pollution, neither environmental protection is also dangerous.
A kind of cooled with liquid nitrogen method is adopted in single preparation with regard to acetone working medium class heat pipe, and namely the heat pipe of an end closure fills after the medium-acetone, is placed on cooled with liquid nitrogen to solid state, it is vacuumized again, and the heat pipe preparation is finished in last pressure welding.This kind method, operation is various, and will follow the consumption liquid nitrogen, and cost is high, can not actively apply.
Aluminum and aluminum alloy mateial, although thermal conductivity is slightly poorer than copper material, its abundant raw materials, reserves are large, cheap etc., along with hot transmission radiating area research not very deeply, day by day become the optimal selection that substitutes copper heat pipe.But but be faced with in the topping up situation, be difficult to its aluminium matter heat pipe such as is effectively sealed at the technical barrier.
It is very high that the aluminothermy pipe requires preparation technology.Especially the requirement of sealing process is tighter.Especially the requirement of sealing process is tighter.Present existing multiple mouth-sealing method, wherein a kind of method be by cold welding tong with topping up heat pipe pinched-off seal, this mouth-sealing method is relatively more fragile, cannot stand collision impact, when operating pressure was slightly large in the pipe, the mouth of pipe may be broken through.As cold welding tong, absolute reliable in when sealing, particularly in manual pinch off situation, in pinch off moment, shake is arranged a little, will cause the sealing defective but heat pipe is scrapped.
The present invention proposes a kind of realization and vacuumizes, fills working medium, seals integrated interface arrangement then for this technical bottleneck, and is practical.Interface arrangement volume of the present invention is little, easily produces, and is flexible for installation, simple to operate, utilizes this device to produce heat pipe, need not the operations such as pressing, welding, improves heat pipe production efficiency and yield rate, and automaticity is high, therefore has huge economic and social profit.
