Abstract
The manufacture includes the steps of annealing copper or aluminum material, arranging in a vibrator, reverse extruding to form in dies of punch and press, adding fluid, and final vacuum electroplating to form heat conducting superfine powder film. The regenerative miniature heat exchanger has small volume, light weight, large heat exchange amount and high heat transferring efficiency.
Description
The invention relates to a kind of miniature heat exchanger manufacture method, refer to that especially kind of the transmission of heat is the storage via the heat conduction ultra-micro powder, then is released to the manufacture of regenerative miniature heat exchanger that reaches heat exchange effect in the fluid again.
The heat exchanger that present laptop inside is installed, include: Al squeezing material heat exchanger, aluminium die casting heat exchanger and the small heat pipe exchanger of copper etc. are multiple.More as can be known, only the small heat pipe exchanger of copper is best for the transmission of heat by subordinate list (1), and heat transfer coefficient is near 10W/m
2℃.
But the small heat pipe type heat exchanger of copper remains in following shortcoming: must solder brazing under ultralow vacuum in (1) production run, and its finished surface oxidation, cost is very high; (2) its quality is subjected to the influence of mean free path, thereby its use is subjected to length restriction; Simultaneously, (3) its heat radiation is higher, and Yi Zaire transmits in the way and disengages, and causes the internal body mechanical temperature to smoulder, and can not be used for three-dimensional.
The objective of the invention is to overcome prior art and not enoughly propose that a kind of production cost is low, output big, be fit to the manufacture of regenerative miniature heat exchanger produced in enormous quantities, and density height, the wall made with this method are thin, area of dissipation is big, the good regenerative miniature heat exchanger of three-dimensional heat transmission.
The objective of the invention is to be realized by following technical proposals: a kind of manufacture method of regenerative miniature heat exchanger is characterized in that:
Earlier with copper, aluminium ingot (piece) anneal of material, after send in the bobbing machine and to do vibration and arrange, then send in regular turn one dash, the location remakes reverse extruding extrusion forming in the set of molds on the press work, to give: circular, tubular, square, the rectangle or the heat exchanger body of concaveconvex shape continuously, the admission passage of reprocessing fluid after the moulding carries out at last the plated film program of the enhancing surface area of the heat conduction superfine powder that the vacuum plating island arranges again in regular turn.Promptly finish a complicated shape but the little heat exchanger of energy one-time formed volume regenerative little, in light weight, that heat-exchange capacity is big and heat transference efficiency is high.
The invention has the advantages that: (1) is suitable for normal temperature processing, and product is difficult for oxidation purity height; (2) make in reverse extrusion modling mode, product density height, physical strength are big, and the face of base dashes, presses machine direction vertical with product, are fit to the usefulness of three-dimensional heat transmission; (3) can once dash, the ultra-thin-wall porous seat of the above thickness of molded 0.2mm.; (4) adhere in the product inside surface heat conduction of tool thermal conductive resin superfine powder is arranged, endothermic effect is high; (5) can produce continuously in the normal temperature state, output is big, cost is low, meet heat transmission increment principle, the hot surface area that transmits of increase and increase capacity of heat transmission to make one, need the slimming volume little, in light weight in order to being applied to, but the manufacture method of the regenerative miniature heat exchanger that the high industries such as computer, electronics, telecommunication and video signal of heat transference efficiency are used.
