Can, it is widely used in various fields, such as in radiator field, in electronics, electrical industry are applied often based on aluminium alloy extrusions
Material is wanted, as component or the thermal component of machine, there is good heat dissipation performance, while there is moderate price advantage.It is existing
Having as the aluminium section bar of power tube radiator in electronic product is formed by substrate and wing plate, substrate and heating part during use
Part connects, and then radiates by wing plate, is usually all first to be fixed power tube by screw when substrate is connected with power tube
It is welded to circuit board again on the substrate of radiator, the fastening dynamics of screw is not to hold very well, is operated entirely with the sensation of worker,
Crossing pine influences heat transfer, and tension easily produces encapsulation the performance of stress influence power tube, the stress release for generation of expanding with heat and contract with cold
The bad performance that can also influence power tube, and power tube is produced displacement in turn-knob screw, cause a deviation from being pre-positioned
Put, it is irregular after influencing later stage installation or installing, it is welded on circuit board and the turn-knob power of radiator generation is installed very with screw again
Pad is easily damaged, problem above can only be solved by proficiency of workers at present, and each radiator will be processed
Threaded hole or drilling, fabrication and installation process is all cumbersome, these are still solved up for technology.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of clipping aluminum alloy heat sink of elastic clip.
The technical solution adopted by the present invention is：A kind of clipping aluminum alloy heat sink of elastic clip, it is characterised in that including aluminium
Alloy bulk and elastic clip；Aluminum alloy body is equipped with backboard, transverse slat, wing plate and clamping plate, transverse slat be connected on backboard along and both
It is in inverted "L" shape to be mutually perpendicular to overall, and wing plate is connected to above transverse slat and is laterally away from backboard side by backboard one and equidistantly arranges, and presss from both sides
Plate is located at below transverse slat and the upper end is connected by wavy shrapnel with transverse slat away from backboard side, and clamping plate hypomere is arc panel, arc
The arc core axis of shape plate respectively with below transverse slat, it is parallel with the backboard inner face that transverse slat is connected below, it is opposite with arc core on arc panel
The back side be an arc pressure surface, arc pressure surface is close to backboard, the arc panel arc core side and backboard back side is respectively equipped with and arc panel
The parallel limiting slot of arc core axis, elastic clip is U-shaped folder, and two bare terminal ends of U-shaped folder coincide in two limiting slots respectively.
Further, the limiting slot is the groove for being individually recessed backboard and arc panel.
Further, the limiting slot respectively by prominent backboard and arc panel muscle enclose into.
Aluminum alloy heat sink of the present invention using when power tube is placed between pressing plate and backboard, then by two folders of U-shaped folder
Hold end to coincide respectively in two limiting slots, since wavy shrapnel has certain deformability, on U-shaped folder elastic force effect lower platen
Arc pressure surface be pressed on power tube, make power tube on the backboard, it is small to accommodate the constant reliable stress of power, can sufficiently discharge
Expand with heat and contract with cold the stress of generation, improves power tube encapsulation performance, and installation is easy, and the torsion that position will not be produced when screw is fixed is inclined
Phenomenon is moved, first two bare terminal ends of U-shaped folder can also respectively coincide in two limiting slots, then strut pressing plate and backboard with instrument
Power tube is put into, suitable for being first welded to power tube on circuit board in installation heat sink, the weight of circuit board when reducing wave soldering
Amount, the absorption guarantee welding stability of thermal energy when reducing welding, this heat sink makes suitable for expressing technique, after section bar cut-out
Using without thread mill drilling, fabrication and installation process is all fairly simple, suitable for promoting and applying.
