Description
Technical field
The invention belongs to Machine Design and processes field, relate to a kind of light-duty folding the two-sided aluminium soldering frock of fin cold drawing。This frock achieves certain light-duty high efficiency two-sided welding folding fin cold drawing, possesses piece-holder fast, accurate positioning, convenience, the advantages such as soldering part deformation is little, it is adaptable to the high-volume aluminium soldering of this cold drawing produces。
Background technology
Population unit is quite strict to overall dimensions and the weight demands of certain portable reconnaissance radar, whole reconnaissance radar small volume, in radar, the heat consumption of each subsystem is higher, and some subsystem also has the feature that localized heat density is high, brings a difficult problem to the heat dissipation design in structure。This radar uses the theory of Integrated design, adopt integrated altogether wall module designs, cold drawing integrated heat dissipation, distributed power source method carry out loss of weight and process with reducing power consumption, successfully achieve lightness and the high-power heat-dissipation requirement of radar。
Cold drawing is the core devices of radar heat radiation, and cold drawing has the requirement of lightweight and high heat-sinking capability。Multiple powerful DSP and fpga chip in the signal processing printed board of radar, ripple control machine printed board are delivered to cold drawing by flexible chill bar。Owing to chip height is inconsistent, several sizes need to be designed in cold drawing surface, highly different cushion blocks could realize chip surface attach heat radiation。The additionally one side of cold drawing is radiating fin, these radiating fins should meet thickness as far as possible thin, along the requirements such as many as far as possible of cooling flow path direction array fin。
Cold drawing has two kinds of processing technique forming methods。The first be directly on milling machine by whole thick aluminium sheet Milling Process out, including the double-edged height cushion block of part with along the many arrays fin cooling down flow path direction。Now, it is contemplated that the manufacturability of processing, these fins can not be too thin, and thickness can not less than 1mm；Another kind is the method by vacuum Aluminum brazing, a sheet of planar aluminium sheet, radiating fin and various cushion block is welded together。According to the former, the processing capacity of part is too big, and needs repeatedly heat treatment in the course of processing, and the especially radiating fin of 1mm thickness, the part process-cycle is long；When adopting the aluminium foil fin folded through vacuum Aluminum brazing molding, the aluminium foil fin of lightweight possesses good heat dissipation, lightweight advantage。Aluminium foil is folded into fin and had both enhanced the rigidity that aluminium foil is overall, increase again area of dissipation。The aluminum foil material thickness folding into fin is only 0.1mm, compare the 1mm thickness of Milling Process, and weight saving is a lot。The fin linear cutter at the angle of inclination that cold drawing welding is required completes, and adopts Vacuum Al-brazing Process method, itself and heat dissipation cold plate is welded into an overall cold drawing, meets the cooling requirements that radar is overall。
Owing to population unit is very strict to weight demands, so except the installation mating surface of cold drawing, the equal Milling Process of all the other end faces goes out to alleviate groove。The body thickness of cold drawing is 2mm, and the groove depth alleviating groove is 0.8mm。The fin folded is welded, the heat conduction cushion block that additionally one side welding is different from the height that printed board chip attaches at the end face that alleviates alleviating groove。At fin and cold drawing, between heat conduction cushion block and cold drawing, fill the thick solder of 0.1mm respectively。When carrying out vacuum Aluminum brazing, solder melt, by fin with cold drawing, heat conduction cushion block together with cold drawing seamless welding。
During high-temperature soldering, with working plate, two soldering parts need to be compressed, to guarantee that solder between the two can be sufficient filling with gap after thawing。Cold drawing adopts welding technique molding。The welding method taked at first is to compress, with whole working plate, the one side having fin, additionally the heat conduction cushion block in one side adopts stainless steel screw to secure it within cold drawing, each cushion block at least processes the screwed hole of two M2, and what the counterbore face of rigging screw was positioned at cold drawing alleviates groove。When manufacturing experimently in the first batch, it has been found that before welding, the workload of punch on each cushion block tapping and cold drawing face counterbore is relatively big, and these stainless steel screws add the weight of cold drawing virtually。
Due to the working height error of existence ± 0.5mm on the fin oneself height that folds, it cannot be guaranteed that each fin closely can attach with cold drawing during compression tooling plate, welding result is that part fin can not be successfully welded, and percent defective is higher or occurs that part fin is excessive and deform due to decrement。In order to improve series-produced efficiency, need a kind of special welding tooling, realize on cold drawing, not process the technique counterbore that welding is required, it is not necessary to mounting process screw is fitted on packaged for each heat conductive pad on cold drawing, and can ensure that each radiating fin can reliably be attached on cold drawing solder side。
