Description
Technical field
The utility model relates in heat-generating electronic elements heat sink technology field more particularly to a kind of ceramic heat sink.
Background technique
Radiator is a kind of device that the easy heat-generating electronic elements in electric appliance radiate, and mostly by aluminium alloy, brass is made into plate
Shape, sheet, splintery etc., general cooling fin coat one layer of heat-conducting silicone grease in electronic component and radiating rib contact surface in use,
The heat for issuing component is more effectively transmitted on cooling fin, then is dispersed into surrounding air through cooling fin.Aluminium alloy,
Its heat dissipation effect of the radiator that the materials such as brass are done has reached the limit, electrical apparatus insulation effect difficult to realize, while not corrosion-resistant,
Service life is short, although having the report that ceramic material is used for radiator, such as patent No. in the prior art
The ceramic heat sink of a kind of high-power LED lamp module or lamps and lanterns described in 201220007382.7, although using ceramic work has been used
For radiating bottom plate and heat dissipation column material, but general ceramic material is used, thermal column is dissipated in the equal cylinder design of height
Plume and radiating bottom plate gluing bond, and are not easy to the replacement of thermal column, heat dissipation effect is limited, and use scope is relatively narrow.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of ceramic heat sink, efficiently solves in background technique
Relevant issues.
In order to solve the above technical problems, the utility model provides the following technical solutions:
A kind of ceramic heat sink, including ceramic bottom board, ceramic heat-dissipating column, the ceramic bottom board is equipped with blind hole, described blind
Ceramic heat-dissipating column is installed, the ceramic heat-dissipating column is designed in up-narrow and down-wide trapezoid cylinder, and ceramic heat-dissipating top end is arc on hole
The angle of shape, arc and perpendicular is 4-7 °, is set on the ceramic bottom board there are two fixed screw holes, for fixing ceramic bottom
Plate.
As the further scheme of the utility model, the height of the ceramic heat-dissipating column is differed, difference in height 10-20mm.
As the further scheme of the utility model, the ceramic heat-dissipating column is threadedly secured on ceramic bottom board.
As the further scheme of the utility model, the ceramic bottom board and ceramic heat-dissipating column all use porous ceramics material
Material, material internal have the through-hole of staggeredly connection.
As the further scheme of the utility model, the ceramic heat-dissipating column is hollow structure, and cylinder is with a thickness of 0.5-
1.5mm。
The utility model uses novel porous ceramic material, by ceramic heat-dissipating post design at up-narrow and down-wide trapezoid cylinder,
Cylinder is hollow structure, and in order to distribute heat preferably, ceramic heat-dissipating post design is at highly differing, while top end of radiating is
The angle of cambered design, arc and perpendicular is 4-7 °, keeps shaping and demoulding high-efficient, and qualification rate increases.
In the utility model, ceramic heat-dissipating column is threadedly coupled with ceramic bottom board, can replace dissipating for different height according to demand
Plume is applicable in various radiating requirements.
The utility model has the beneficial effects that
The utility model radiates, and the time is short, and good heat dissipation effect can make the workpiece temperature for needing to radiate reduce 4-7 DEG C.
Detailed description of the invention
Fig. 1 is the utility model schematic perspective view.
Fig. 2 is ceramic heat-dissipating column enlarged drawing.
In figure, 1- ceramic heat-dissipating column, 2- ceramic bottom board, 3- screw hole.
Specific embodiment
The utility model is further described with specific embodiment below, but the utility model is not by following embodiments
Restriction.
Embodiment 1
As shown in Figs. 1-2, a kind of ceramic heat sink, including ceramic bottom board 2, ceramic heat-dissipating column 1, on the ceramic bottom board 2
Equipped with blind hole, ceramic heat-dissipating column 1 is installed in the blind hole, the ceramic heat-dissipating column 1 is designed in up-narrow and down-wide trapezoid cylinder, pottery
Porcelain radiates top end for arc, and the angle of arc and perpendicular is 5 °, is set on the ceramic bottom board there are two fixed screw holes,
For fixing ceramic bottom board.
Further, in order to distribute heat preferably, at highly differing, difference in height is the ceramic heat-dissipating post design
10-20mm, the ceramic heat-dissipating column are hollow structure, and cylinder is with a thickness of 0.5-1.5mm.
Further, the ceramic heat-dissipating column is threadedly secured on ceramic bottom board, can replace different height according to demand
The thermal column of degree is applicable in various radiating requirements.
Further, the ceramic bottom board and ceramic heat-dissipating column all use porous ceramic film material, and material internal has staggeredly
The through-hole of connection, and then the contact heat dissipation area between porous ceramics cooling fin and air is increased, so that in through-hole duct
Hot and cold air is capable of forming thermal convection, is transferred heat to outside porous ceramics cooling fin in real time, and porous ceramics cooling fin is allowed to tie up
It holds at a lower temperature.
The utility model radiates, and the time is short, and good heat dissipation effect can make the workpiece temperature for needing to radiate reduce 4-7 DEG C.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
