Background technology:
In existing electric equipment, as computer, air-conditioning, in the equipment such as LED lampshade, be equipped with circuit boards such as controlling mainboard, on these circuit boards, be all fixed with a plurality of electronic devices and components, when work, it can produce a large amount of heats, and this caloric requirement is dispelled the heat as early as possible, to guarantee the normal work of circuit board, therefore fin is generally all set on circuit board, yet existing fin is general adopt have an aluminium extruded type fin, aluminum casting fin, aluminium cutting fin, copper cutting fin and aluminum bronze storehouse fin etc., wherein its radiating effect of aluminum thermal fin is poorer than copper fin, and the Costco Wholesale of copper is higher, when aluminum thermal fin need to reach copper fin effect, just volume need to be done greatly, increase than the more contact area heat radiation of copper fin, this cannot dwindle aluminum thermal fin volume, taken space.
And existing fin radiating principle is by heater → heat-conducting layer → insulating barrier → heat-conducting layer → Aluminium Radiator, when heat is transmitted to heat-conducting layer via heater, (thermal effect has certain decay) is being transmitted to heat-conducting layer being transmitted to the insulating barrier very low decay furtherly of its heat conduction such as (), Kapton rare such as polyester, affected radiating effect.
Simultaneously, existing fin is generally comprised of pedestal and radiating fin, radiating fin is generally straight forming or is fixed together by the welding mode such as rivet, in order to improve thermal diffusivity, general make very high of its radiating fin, to increase radiating effect, the height of general radiating fin is the more than 10 times of base thickness, it need to take very large installation and usage space, so just increased the volume of main control system housing, make main control system take larger usage space, and on the fin having, also can directly be fixed with fan and further improve its radiating effect, its general employing buckle-type is fixed or makes one with fin, buckle-type make fin and fan buckle tightr, when needing repairing, during its dismounting into two with one's hands, snap part need to be broken cumbersome, and fin and fan are while making integral type, when fan breaks down or needs to carry out integral replacing when fin damages, cannot carry out part replacing, formed waste, increased maintenance cost.
Simultaneously, on existing fin if can provided with fan, on it, straight forming has installation portion or the installing hole of fan, and installation portion or installing hole be not set on fin just cannot provided with fan, when making to install, this need to know which kind of fin circuit board needs, two types cannot be general, same, some fin are bolted on circuit board, some is bonded on circuit board by binding agent, these two kinds of fin also cannot be general according to difference is installed, and this has improved the requirement of selection and type selecting.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of high thermal conductivity fin, it adopts aluminium oxide ceramics thermal conductivity good, and meanwhile, the contiguous block of the fan connecting plate on it and fixedly use all can be dismantled, meet various installation requirements, improve degree flexible for installation, improve the versatility of fin, and it is less than existing fin volume in the situation that guaranteeing that radiating effect is identical, weight is lighter, reduces space hold.
Technology solution of the present utility model is as follows:
A kind of high thermal conductivity fin, comprise pedestal, on pedestal, in plane, form a plurality of radiating fins, described pedestal and radiating fin are alumina ceramic material and make, on pedestal, form long through groove, long through groove one end passes the left side wall of pedestal, the right side wall that the other end passes pedestal, forms vertical a plurality of openings on radiating fin, the bottom of opening communicates with long through groove, and the upper surface that the top of opening passes radiating fin communicates with the external world;
Between adjacent two radiating fins, form circulation groove; In the place, two ends, left and right of the front and back dual-side of pedestal, be bolted to connection L shaped contiguous block, on the base plate of contiguous block, form connecting through hole, in the slot that the two ends, left and right of fan connecting plate form in the slot that the protruding sleeve of projection, its left end forms on the right side of the base plate of the adjacent contiguous block of the projection with left end, the protruding sleeve of its right-hand member forms on the left side of the base plate of the adjacent contiguous block of the projection with right-hand member, on fan connecting plate, form a plurality of fixing threaded holes, fixing threaded hole is corresponding one by one up and down with the installing hole of fan;
The thickness of pedestal is 1/3 to 1/5 of radiating fin height.
Described L shaped contiguous block by bending and molding in a side direction of base plate and base plate by connecting portion form, the two ends, left and right that the connecting portion of four L shaped contiguous blocks is fixedly connected on respectively the front and back dual-side of pedestal by bolt are located.
The cross section of described long through groove is rectangle.
The width of described each circulation groove equates.
Described pedestal is cuboid.
The opening forming on the upper surface of described each radiating fin is arranged in a straight line, and the spacing of each opening equates.
The beneficial effects of the utility model are:
1, it adopts aluminium oxide ceramics to make, and it can directly be fixed on heater, and heat is directly via the conduction of this fin one, and the dissipation of the heat of can not decaying because there being insulating barrier can be taken away more heat within the same unit interval, improves thermal conductivity.And employing aluminium oxide ceramics, it is lightweight, can be when keeping same radiating effect, and its volume is all less than the fin of fine aluminium system, and cost is lower than the copper cooling fin of effect same.
Its building block can be dismantled, and meets various installation requirements, improves degree flexible for installation.
2, its fan connecting plate and fixedly the contiguous block of use all can dismantle, meet various installation requirements, improve degree flexible for installation, improve the versatility of fin.
3, on its pedestal, form the long through groove that left and right communicates, on the upper surface of radiating fin, form a plurality of openings, the bottom of opening communicates with long through groove, the top of opening communicates with the external world, air can enter from the two ends of long through groove like this, from opening, discharge, thereby take away the heat of fin inside, so not only by circulation groove, take away the heat of fin outside, also taken away the heat of fin inside, double-radiation function improves its radiating effect completely, can guarantee that so the existing fin volume of ratio of making in situation that radiating effect is identical is less, weight is lighter, therefore the thickness of its pedestal can be 1/3 to 1/5 of radiating fin height, greatly reduce space hold.
4, its space hold is little, and the housing of its main control system being arranged on can be dwindled, and reduces its volume, makes the main control system can be more frivolous.
