Description
Affiliated technical field
The present invention relates to a kind of fluid heat exchanger manufacture method, especially pipeline and intert the work calories that can utilize semiconductor integration module in the radiating fin manufacture method as the blade inserting fluid heat exchanger of power source propelling fluid phase-change circulation of working medium heat exchange.
Background technology
At present, utilize the work calories of semiconductor integration module to originate from heat-pipe radiator as power source promotion blade inserting fluid heat transferring, every heat pipe vertically interts in radiating fin as heat transfer element, hot intraductal working medium is to accept heat by axial evaporation heat transfer by hot junction, become after heat pipe cold junction through radiating fin heat exchange condensation, by radially absorbing liquid, utilize siphon power and gravity to reflux by incoming road, form working medium and in pipe, carry out diameter of axle circulation, because this endless form refluxes slow, working medium amount is few, substantially be to utilize fluid heat transferring, phase variable is little, several without exchange capability of heat, heat is main or the radiating fin of making by good heat conduction solid exchanges, therefore replaced by genuine fluid heat exchanger afterwards, in fluid heat exchanger, working medium is to accept heat by axially realizing evaporation at heat exchange source place by evaporation tube, enter the condenser pipe being inserted in radiating fin and carry out heat exchange, after condensation, assemble and conflux into liquid by tube wall, enter evaporation tube heat exchange source place by return duct by choke valve and accept again heat, form circulation line, working medium is carried out one-way circulation in circulation line, pipeline route is long to reflux soon, can connection in series-parallel, several times improve working medium amount, fill a prescription by working medium, increase the ratio that working medium undergoes phase transition, fluid phase change heat exchange is mated with radiating fin heat exchange ability, several times improve exchange capability of heat, the effect that improves high power semi-conductor integration module is played to irreplaceable effect, but, wherein radiating fin employing thickness is 0.1-0.4mm aluminium matter thin plate, in order to possess the ability of flash heat transfer, heat pipe vertically or at a certain angle tilts to intert and is welded to each other in the assembling circular hole of radiating fin side, the folded bottom of radiating fin and heat exchange base plate radiating surface are welded to each other, it is the above pure aluminum plate of 2.5mm that heat exchange base plate adopts thickness, so the surface of aluminium matter radiating fin and heat exchange base plate does not possess group's weldering property, need first aluminium matter part to be immersed in chemical nickel liquid, make it all surfaces and carry out material modification by 8 one 16 millimicrons of nickel dams of the general plating of strong ion, then could in Reflow Soldering, realize welding grows up to be a useful person, the surface of actual participation welding only accounts for 58% of all surfaces, more than 90% modification is not necessary, with few take many, heat is by surface exchange, nickel is slower than aluminium heat exchange rate, seemingly cover one deck heat resistance film tool barrier, what is more important chemical nickel electroplating technology does not meet environmental requirement, must progressively abandon.
Summary of the invention
There is electroplating technology and the large drawback of noble metal wastage for fear of existing fluid heat exchanger manufacture, the present invention is a kind of only applies laser modified technique in aluminium matter piece surface welding position, be about to need welding position to be designed to pattern, adopt the method for printing material spray, make surface, welding position according to layout coated alloy scolder, coating can divide once or twice, by laser scanning and hot reflux scan mode, only make within the scope of layout coating, accepting in laser and backflow pyroprocess, there is redox reaction, destroy the firm oxide layer formation alloy ginseng in aluminium surface and ooze the partial modification causing with alloy pellicle, alloy pellicle is electroplated and is had more good conductive welding basis than chemical nickel, reach the object that more easily welding is grown up to be a useful person.
The technical solution adopted for the present invention to solve the technical problems is: a kind of manufacture method of combining closely with semiconductor integration module thermal conductive surface and utilizing phase-change circulation of working medium fluid heat exchanger in its work calories driving pipeline, the radiating fin made from aluminum material, heat exchange base plate is as part, first need the position being welded to each other to be designed to pattern, adopt the method for numerical control spraying, make surface, aluminium matter welding position apply congee sample solder according to layout, the solder formula applying is different, can divide once or twice, disposable coating material is taken into account ginseng and is oozed and pellicle, secondary coating material is divided into once lays particular stress on ginseng and oozes secondary and lay particular stress on film forming, then thickness is less than to the thin plate of 0.5mm by the mode of laser scanning, pulsewidth regulation and control laser energy intensity, laser only scans coat, through coat and aluminium surface oxide layer, make within the scope of layout coating, accepting in laser pyroprocess, the redox reaction formation alloy ginseng occurring is sharply oozed the partial modification causing with alloy pellicle, moment completes material modification and realizes thus solderability, thickness is greater than to the heat exchange base plate that 2.5mm pure aluminum plate is made, except adopting laser, also can adopt the modification of backflow high temeperature chemistry, part assembles according to structural requirement after getting ready, by radiating fin parallel arrangement, condenser pipe axially vertically or at a certain angle tilts to intert in the assembling circular hole of radiating fin, evaporation pipeline axially vertically or at a certain angle tilts to be placed in the arcuate channels of radiating fin, the radiating fin folded bottom of modification is aimed at heat exchange base plate radiating surface modification position, and in the gap of above-mentioned assembling between two or apply the congee sample cored solder that contains scaling powder in the hopper of gap, completing assembling applies after cored solder, put into shape-setting clamp, by Reflow Soldering, evaporation tube outer surface and arcuate channels medial surface are welded to each other, condenser pipe outer surface is welded to each other with assembling circular hole medial surface, the folded bottom of radiating fin and heat exchange base plate radiating surface are welded to each other, make the fluid heat exchanger that can utilize semiconductor integration module work calories to carry out heat exchange, complete thus the manufacture method of blade inserting fluid heat exchanger.
The invention has the beneficial effects as follows and make the thorough electroplating technology that departs from fluid heat exchanger manufacture process, omnidistance technique realizes environmental protection, a large amount of noble metals of saving, after product rejection, be convenient to each composition in product and separate, re-use, be beneficial to non-ferrous metal and form recycling economy, significantly reduce product cost, be particularly useful for the work calorieses such as high power semi-conductor temperature difference device, power supply, power amplifier, infrared, laser, radar generator large, the manufacture of the heat exchanger that heat density is high.
