The utility model discloses an oxidation prevention device of a heat conducting medium for metal alloy with low melting point, which comprises a radiator, an oxidation prevention layer and a material piece of the metal alloy with low melting point. The material piece of the metal alloy with low melting point is arranged on the radiator and is used as a heat conducting medium which is in contact with a heating source. The oxidation prevention layer made of pressed material is arranged on the radiator, is in a frame shape and is besieged outside the material piece of the metal alloy with low melting point. Thereby, the invasion of air is effectively prevented to isolate the contact of the material piece of the metal alloy with low melting point with outer air; thereby, the oxidation of the material piece of the metal alloy with low melting point is prevented to make the material piece of the metal alloy with low melting point have optimal heat conduction efficiency.
Description
Technical field
The utility model relates to a kind of anti-oxidation device of low-melting point metal alloy heat-conducting medium, relate in particular to a kind of in order to prevent the air intrusion, contact with extraneous air with isolated low-melting point metal alloy material, can prevent the low-melting point metal alloy material oxidation, make it have the anti-oxidation device of preferable heat conduction efficiency.
Background technology
Along with computer industry develops rapidly; the execution speed of chip, CPU pyrotoxins such as (CPU) is more and more fast; the caloric value of relative pyrotoxin is also more and more high; for the high temperature that pyrotoxin produced is discharged in the external world; make pyrotoxin can the permission temperature under normal operation; usually can be attached on the excessive hot surface of pyrotoxin to have the larger area radiator, utilize a plurality of fins of radiator to assist heat radiation.As announce in Taiwan patent tw562395 number of November 11 2003 Christian era and promptly disclose existing heat abstractor.
For the heat that pyrotoxin is produced can be certain be passed to radiator, generally need between pyrotoxin and radiator, to be provided with heat-conducting cream, this radiator borrows heat-conducting cream to contact with pyrotoxin, so that utilize heat-conducting cream and radiator that the high temperature that pyrotoxin produces is derived, in order to assist the pyrotoxin heat radiation.
Above-mentioned existing heat abstractor utilizes heat-conducting cream as heat-conducting medium, because the coefficient of heat conduction TC of heat-conducting cream is lower, therefore heat conduction efficiency is relatively poor, make to be difficult to effectively be passed to radiator by the high temperature that pyrotoxins such as chip, CPU produce, make its radiating efficiency relatively poor.
Other has a kind of heat abstractor relevant with the utility model, the low-melting point metal alloy material is fixed in the radiator bottom, thereby can utilize the low-melting point metal alloy material as heat-conducting medium, this low-melting point metal alloy material coefficient of heat conduction is higher, the heat that makes pyrotoxin produce can effectively be passed to radiator, to have preferable radiating efficiency.
Above-mentioned heat abstractor with the low-melting point metal alloy material as heat-conducting medium, this low-melting point metal alloy material is if utilize spraying method to be arranged at the radiator bottom, itself promptly have bubble (cavity) and produce, there is the low-melting point metal alloy material internal in air, can cause heat conduction efficiency to reduce.But the problem of this inner air generally can be reduced or adopted mode such as sheet moulding and be improved by low-melting point metal alloy material spraying granularity.
Above-mentioned low-melting point metal alloy material is arranged between pyrotoxin and the radiator, when the pyrotoxin working temperature higher, when the fusing point of arrival low-melting point metal alloy material is above, low-melting point metal alloy material liquefy, and then generation is mobile, and owing to low-melting point metal alloy material outer rim directly contacts with extraneous air, so air can be invaded the low-melting point metal alloy material by the outside, and then cause the oxidation of low-melting point metal alloy material, its heat conduction efficiency is reduced.
Therefore, as from the foregoing, above-mentioned existing heat abstractor on reality is used, obviously has inconvenience and exists with disappearance, and can wait to be improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-oxidation device of low-melting point metal alloy heat-conducting medium, in the radiator bottom one antioxidation coating is set, this antioxidation coating is centered around this low-melting point metal alloy material pieces outside, make when the low-melting point metal alloy material pieces is arranged between pyrotoxin and the radiator, can effectively prevent the air intrusion, with contacting of isolated low-melting point metal alloy material pieces and extraneous air, thereby can prevent the oxidation of low-melting point metal alloy material, make it have preferable conduction efficiency.
In order to realize above-mentioned purpose, the utility model provides a kind of anti-oxidation device of low-melting point metal alloy heat-conducting medium, comprising: a radiator; One low-melting point metal alloy material pieces is arranged on this radiator; And the antioxidation coating made of compressible material, being arranged on this radiator, this antioxidation coating is a frame type, is centered around this low-melting point metal alloy material outside.
Adopt the utility model can effectively prevent the air intrusion, with contacting of isolated low-melting point metal alloy material pieces and extraneous air, therefore air can't be invaded the low-melting point metal alloy material pieces by the outside, thereby can prevent the oxidation of low-melting point metal alloy material pieces, make it have preferable heat conduction efficiency.
For enabling further to understand feature of the present utility model and technology contents, with reference to following about detailed description of the present utility model and accompanying drawing, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the utility model is limited.
