Abstract
A sealing structure for a vapor chamber comprises a face open type operation hole, an extension pipe part and a low-melting-point press-fit part. The face open type operation hole is formed in the position, close to an annular press-fit edge, of a plate face of an upper cover plate and is in a form that the face open type operation hole communicates with a hollow cavity, and accordingly the face open type operation hole can be used for vacuum pumping and liquid injection work of the hollow cavity. The extension pipe part is integrally formed in the face open type operation hole and is in a form that the extension pipe part extends in the hollow cavity in a protruding manner. The low-melting-point press-fit part is arranged on the inner face of a lower cover plate in a positioning state and located at the position, opposite to the position where the face open type operation hole is formed, in the upper cover plate, the upper end of the low-melting-point press-fit part upwards penetrates the extension pipe part in an extending manner, interval space is formed between the low-melting-point press-fit part and the extension pipe part, and a fusion pressed part is arranged at the upper end of the low-melting-point press-fit part and upwards protrudes and extends to the position of the upper end of the face open type operation hole. The melting point of the material of the low-melting-point press-fit part is lower than that of the material of the upper cover plate. The periphery of the upper cover plate and the periphery of the lower cover plate can be manufactured into the annular combined sealed state, the face open type operation hole of the sealing structure conforms to the good mechanism generatrix of related machining equipment, in addition, no welding flux needs to be used for welding and sealing, the manufacturing procedures are simpler, the problem of welding flux pollution is avoided, and environment friendliness is better achieved.
Description
Technical field
The present invention relates to a kind of temperature-uniforming plate, particularly relate to the innovative technology of the enclosuring structure of described temperature-uniforming plate.
Background technology
The configuration of existing temperature-uniforming plate, is generally repeatedly leaned on mutually by a upper cover plate and a lower cover and is executed by the two periphery
Constituted combining technique for fixing；And wherein, the periphery of described upper cover plate and lower cover is after completing to combine fixing step, still
A breach must be reserved, to utilize this breach to carry out the steps such as the evacuation within follow-up temperature-uniforming plate and fluid injection, the most again should
Breach passes through solder welded closure.
But, the configuration of above-mentioned existing temperature-uniforming plate and molding mode, find still to exist in practical application experience
Some problems and scarce fraud because described breach be typically to utilize upper cover plate in time stamping out three-dimensional shape of hood in its periphery in the lump
Stamp out half tube shape to be constituted, until with lower cover repeatedly by forming an opening after combining towards lateral breach, but this kind is scarce
Mouthful formation, except its lateral openings form and do not meet related processing equipment the shortcoming of the preferable moving-wire of mechanism in addition to, described lack
The ideal form that upper cover plate can be caused originally can be combined closing in the form of a ring with lower cover periphery that arranges of mouth is affected, and causes
The easily breakage of its inner vacuum state is lost and is difficult to keep for a long time, and because this breach is in completing the step such as evacuation and fluid injection
Its manufacturing process must be caused slightly to dislike complicated problem, and the use of described solder again by solder in addition welded closure afterwards
More there is the problem polluted not environmentally.
