Abstract
The utility model discloses a ceramic radiating fin with high thermal conductivity. The ceramic radiating fin with high thermal conductivity comprises a pedestal and heat radiation fins. The pedestal and the heat radiation fins are made of alumina ceramic material. Multiple dovetail-shaped clamping grooves are molded on the upper plane of the pedestal. Dovetail-shaped projection strips are molded on the bottoms of the heat radiation fins. The dovetail-shaped projection strips are clamped in the dovetail-shaped clamping grooves through interference fit. Multiple through holes are molded in the pedestal. One end of each through hole passes through one sidewall of the pedestal, and the other ends of each through holes pass through the other sidewall of the pedestal. Multiple through holes are molded in the heat radiation fins. A circulation groove is formed between every two adjacent heat radiation fins. L-shaped connecting blocks are fixedly connected with the right and left sides of the pedestal through bolts. Connecting holes are molded in base plates of the connecting blocks. The ceramic radiating fin with high thermal conductivity is good in thermal conductivity, small in size and light in weight. In addition, the component parts can be dismounted to satisfy different installation demands, so that the installation nimbleness is improved.

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 multiple electronic devices and components, in the time of work, it can produce a large amount of heats, and this caloric requirement is dispelled the heat as early as possible, to ensure the normal work of circuit board, therefore fin is generally all set on circuit board, but existing fin 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, in the time that aluminum thermal fin need to reach copper fin effect, just volume need to be done greatly, increase and dispel the heat than the more contact area of copper fin, this cannot dwindle aluminum thermal fin volume, take space.
And existing fin radiating principle is by heater → heat-conducting layer → insulating barrier → heat-conducting layer → Aluminium Radiator, in the time that 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.
Meanwhile, it is all generally integrated for existing fin, or fixes by the mode of riveted joint, welding, and the parts of its composition cannot separate, and reduce its Installation Flexibility, and cannot adjust according to installing space, and impact is installed.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of high thermal conduc tivity ceramics fin is provided, and its thermal conductivity is good, volume is little, lightweight, simultaneously, its building block can be dismantled, and meets various installation requirements, improves degree flexible for installation.
Technology solution of the present utility model is as follows:
A kind of high thermal conduc tivity ceramics fin, comprise pedestal and radiating fin, described pedestal and radiating fin are alumina ceramic material and make, in the upper plane of pedestal, form multiple swallow-tail form draw-in grooves, on the bottom of radiating fin, form swallow-tail form raised item, swallow-tail form raised item passes through interference fit holding in swallow-tail form draw-in groove; On pedestal, form multiple through holes, through hole one end passes a sidewall of pedestal, another sidewall that the other end passes pedestal;
On radiating fin, form multiple through holes, between adjacent two radiating fins, form circulation groove; On the limit, the left and right sides of pedestal, be bolted to connection L shaped contiguous block, on the base plate of contiguous block, formed connecting through hole.
Described L shaped contiguous block by bending and molding in a side direction of base plate and base plate by connecting portion form, the connecting portion of four L shaped contiguous blocks is fixedly connected on respectively the rear and front end place of left side wall and the right side wall of pedestal by bolt.
Described through hole one end passes the left side wall of pedestal, the right side wall that the other end passes pedestal, and the central axis of through hole parallels with the bottom surface of pedestal, and the spacing between every two adjacent through holes equates.
In the upper plane of described pedestal, form multiple raised items, form the swallow-tail form draw-in groove all running through with front side wall and the rear wall of raised item on raised item, the spacing between every adjacent two raised items equates.
Circulation groove spacing between described every adjacent two radiating fins equates.
The lead to the hole site forming on described all radiating fins all front and back is mutually corresponding one by one.
Described pedestal is cuboid.
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 in the time 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, it substantially form through hole, air can be circulated, thereby takes away more heat, improve the effect of heat exchange, thereby improve thermal diffusivity.
3, its radiating fin, pedestal, contiguous block all can split, this sample fin can be bolted on circuit board according to the requirement of board design, can, by being bonded on circuit board and dispelling the heat by binding agent after dismounting contiguous block, improve the flexibility of installing equally.And radiating fin can be changed according to the size of installing space, in the time that installing space is smaller, the model that radiating fin can be changed into length, height or small volume is installed, and interchangeability is good.
4, the through hole on circulation groove and the radiating fin having between its radiating fin all further improves the heat transfer effect between itself and air, further improves its thermal diffusivity.
