Abstract
The utility model discloses an injection molding porous ceramics radiator structure, which is made from ceramics materials, and comprises a heated bottom plate and two or more heat dissipation fins which are formed on the heated bottom plate, wherein the ceramics materials which are made into a radiator is injected to form through a twice foaming process in a milling mixing process. Particulates contained by the ceramics materials are finer during the homogenization process of the ceramics materials through twice foaming, thereby according with a porous structure which is needed by a radiator finished product, and achieving needed heat dissipation demands and standard.
Description
Technical field
The utility model is relevant for a kind of ceramic heat sink, refers to a kind of by the second time of foaming program and the porous ceramics radiator of ejection formation especially.
Background technology
At present, cellular structure is except can be applicable on the parts such as bearing, axle center, outside the effect that oil-containing (holding oil) is provided, also because its porous can increase the touch opportunity with air, also can bring into play good effect and effect aspect heat radiation.
Utilize ceramic material to make cellular structure and be common now technology.Yet, in order to make the ceramic material of cellular structure, make the more careful loose structure in aperture in the past, often depend on raw material itself, just there is the restriction on the material.If can pass through consistent manufacturing process, when the restriction that makes raw material can meet demand and raw material after completing also is unlikely to become main consideration condition, then can significantly reduce on the technology, the many costs on the material, and meet the final radiating requirements of radiator finished product.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of porous ceramics heat spreader structures of ejection formation, meets the required porous structure of radiator finished product, can reach required radiating requirements and standard.
To achieve the above object, the utility model provides a kind of porous ceramics heat spreader structures of ejection formation, and it is made by ceramic material, and comprises and be heated base plate and be formed at two or more radiating fins on the base plate that is heated; Wherein, make the ceramic material of this radiator, in mixing program, carry out the second time of foaming program and ejection formation.
Reach the detailed-oriented demand in aperture via described second time of foaming program, to reach above-mentioned purpose.
As can be seen from the above technical solutions, the porous ceramics heat spreader structures of ejection formation of the present utility model, it is by carrying out second time of foaming to the ceramic material of making radiator in the mixing program of its forming process; Make ceramic material in the process that homogenizes by second time of foaming, can make it particles contained more tiny,, reach required radiating requirements and standard to meet the required porous structure of radiator finished product.

The specific embodiment
In order to make feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only be used to provide with reference to and explanation, be not to be used for the utility model is limited.
See also Fig. 1, be the stereogram of the porous ceramics radiator of the utility model ejection formation knot.The utility model provides a kind of porous ceramics heat spreader structures of ejection formation, this radiator 1 comprises and is heated base plate 10 and is formed at two or more radiating fins 11 on this base plate 10 that is heated, and this radiator 1 is by made as ceramic materials such as oxide, nitride or carbide.
From the above, this radiator 1 carries out in the intimate mixing program at ceramic material on making, and adds as dry type blowing agent expanded materials such as (AC), after the program of do foaming for the first time earlier, carries out the foaming second time again.And the program that foams compared to the described first time, described second time of foaming be in more increase temperature, under the environment of high pressure, so that homogenize and to contain the formed particle of pseudo plastic ceramic material of particulate more tiny.
Then,, ceramic material is made the required shape of aforementioned radiator 1 again by as the injection forming method or the technology of ceramic materials such as Jet forming machine, and by take off porcelain, the sintering supervisor is finished finished product.
Therefore, by above-mentioned contexture, can obtain the porous ceramics heat spreader structures of the utility model ejection formation.
In view of the above, as shown in Figure 2, base plate 10 bottom surfaces that are heated at this radiator 1 attach one deck heat-conducting layer 2, this heat-conducting layer 2 is can be by the good material of thermal conduction characteristics such as aluminium or copper made or directly heat-conducting layer 2 is added base plate 10 belows that are heated, and form incorporate conductive structure, make its tool heat absorption, heat conduction function, contact to develop, and then be beneficial to heat conduction with pyrotoxin 3.So, because this radiator 1 has porosity characteristic, so after the heat absorption that heat-conducting layer 2 is produced pyrotoxin 3, can reach the purpose of quick heat radiating by the cellular structure of this radiator 1.
Therefore, by the porous ceramics heat spreader structures of the utility model ejection formation, can pass through consistent manufacturing process, make the ceramic material of making radiator in forming process, reach the detailed-oriented demand in aperture via the second time of foaming program, with significantly reduce on the technology, manufacturing cost on the material.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model, so the equivalent structure that any utilization the utility model specification and accompanying drawing content are done changes, in like manner all is included in the scope of the present utility model.
