Description
Technical field
The present invention relates to a kind of soaking plate, especially a kind of enclosuring structure of soaking plate and manufacture method thereof.
Background technology
Soaking plate is a kind of high performance heat abstractor, be used on the high performance electronic element more, its basic structure is the shell with a vacuum chamber, in chamber, be provided with micro-structural, and the filling hydraulic fluid, solidify, evaporate the suction, heat radiation and the micro-structural that produce by hydraulic fluid the capillary force of hydraulic fluid is carried out the heat conduction; The structure of soaking plate needs inner vacuum, existing soaking plate manufacturing technology, no matter the formed inner chamber of lid about being, or by copper pipe via the formed inner chamber of die mould, its production stage as shown in Figure 1, include: the step of filling out powder, sintering formation capillary portion of leading portion part, insert the step of supporting construction, die mould, the welded seal of argon welding, silver soldering and insert the step of a thin metal pipe as liquid injection port, in chamber, inject the step of hydraulic fluid by thin metal pipe, and the quantitative fluid injection of back segment part, vacuumize and seal the step of welding.
The manufacturing technology of existing soaking plate exists following deficiency:
Through soaking plate and the semi-finished product that the step of above-mentioned leading portion part is produced, in the welded seal process, can use a thin metal pipe as the liquid injection port of reserving, structure as shown in Figure 2, wherein 1 ' is the soaking plate semi-finished product, 2 is the sealing part structure, 3 is thin metal pipe; Such structure is as easy as rolling off a log because of accident collision damages when follow-up manufacturing and use, causes soaking plate to become defective products.
And, when the soaking plate semi-finished product are implemented the back segment manufacturing step, for quantitative fluid injection, vacuumize and seal the operation of welding, existing technical scheme is that the liquid with impregnator injects the metal liquid injection pipe on the soaking plate, just removes this impregnator after reaching certain quantity of fluid; Next just these soaking plate semi-finished product are moved on to next work station, vacuumize operation; Seal weld job subsequently again, so operation is consuming time takes a lot of work the manufacturing cost height.
In addition, because the inside cavity high vacuum causes pressure to descend, use same opening to do fluid injection and the mode of the operation mouth that vacuumizes, when fluid injection, be easy to generate the phenomenon that liquid level is vaporized rapidly, the careless slightly liquid insufficient infusion that will make, and then cause taking place easily dry combustion method (dry out) phenomenon.
Summary of the invention
The object of the present invention is to provide a kind of soaking plate manufacture method of avoiding above-mentioned manufacturing defective, the soaking plate enclosuring structure that provides a kind of nothing to seal defective is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is:
A kind of manufacture method of soaking plate may further comprise the steps:
Step 3, supporting construction is filled: insert supporting construction in the chamber of raw metal;
Step 5 seals one: the remainder except that liquid injection port is sealed;
Step 7, application of vacuum: the soaking plate semi-finished product after at least one fluid injection are inserted arrangement place in the vacuum tank, and pressing also seals the liquid injection port end.
A kind of enclosuring structure of soaking plate, for leaving the semi-finished product of liquid injection port, comprise the soaking plate semi-finished product, with vacuum chamber be positioned at the liquid injection port of soaking plate one side and be arranged at vacuum chamber, in order to support the supporting construction of soaking plate semi-finished product profile, described liquid injection port is the integrate shaped type opening that this side of soaking plate stays after pressing, sealing.
The invention has the beneficial effects as follows: the present invention is after sealing one processing step, do not follow the liquid injection pipe that is solded into of existing scheme, but keep a liquid injection port, after finishing fluid injection, carry out application of vacuum and sealing, being about to arrangement place that the soaking plate semi-finished product insert in the vacuum tank fixes, and in vacuum tank to liquid injection port pressing and sealing, soaking plate by such step is produced does not need thin metal pipe, and can be unified in and carry out follow-up sealing technology in the vacuum tank, and avoided in the soaking plate chamber, the rough sledding that outer pressure reduction brought, make that the properties of product of being produced are good, percent defective is low, has well result of use.
The persond having ordinary knowledge in the technical field of the present invention after reading this manual, it will be appreciated that other purpose of the present invention and advantage.
