The specific embodiment
Relevant detailed description of the present invention and technology contents, be described as follows cooperation accompanying drawing, yet accompanying drawing is only as illustrative purposes, not for limiting to the present invention.
Please refer to Fig. 1 to Fig. 5, the invention provides a kind of temperature-uniforming plate and manufacture method thereof.Temperature-uniforming plate 1 of the present invention comprises: a lower house 10, a upper shell 20, a capillary structure 30, a working fluid 40 and a supporting construction 50.
Similarly, upper shell 20 is roughly in the form of annular discs and can be metal or ceramic material is made, lower house 20 is made into be had a top board 21, take shape in an annular groove 22 of these top board 21 outer rims and extends an epipleural 23 of these annular groove 22 peripheries, and epipleural 23 also offers a through hole 231 and for these gas removing pipe 13 cross-under.
Comparison diagram 4 and Fig. 5, the external diameter of upper shell 20 is slightly less than the internal diameter of lower house 10, causes when upper shell 20 cover caps are during in lower house 10, and epipleural 23 supports and pastes lower side panel 12, and makes to surround between annular groove 22 and lower side panel 12 a scolder accommodating area Z.In addition, the upper limb of lower side panel 12 surpasses the level height of annular groove 22 and roughly flushes in top board 21, and thus, scolder 100 can be undertaken in the Z of scolder accommodating area as shown in Figure 5, and lower side panel 12 can block scolder 100 and avoid scolder 100 leak outside or peel off simultaneously.Certainly, from Fig. 5, can imagine and draw, the upper limb of lower side panel 12 can bend to envelope scolder 100 towards annular groove 22, makes again the periphery of temperature-uniforming plate 1 produce a lead angle simultaneously.
In addition, the inwall of upper shell 20 is integral sintered goes out capillary portion 32 on, and therefore, the upper capillary portion 32 of the lower capillary portion 31 of lower house 10 and upper shell 20 is common forms capillary structure 30 of the present invention.Working fluid 40 (for example: water) fill between lower house 10 and upper shell 20, liquid phase by working fluid 40 changes and the circulation between lower capillary portion 31 and upper capillary portion 32, and the heat that the base plate of lower house 10 11 can be absorbed conducts to the top board 21 of upper shell 20.About the operation principle of temperature-uniforming plate 1, owing to belonging to prior art and not being technical characterictic of the present invention, so omit related description in order to avoid repeat at this.
As shown in Figure 1, between lower house 10 and upper shell 20, be also provided with a supporting construction 50, in order to be supported between the base plate 11 of lower house 10 and the top board 21 of upper shell 20, to prevent that base plate 11 from making whole temperature-uniforming plate 1 depression go down because of ambient pressure or external force with top board 21.Supporting construction 50 comprises a plate body 51 and protrudes from the lip-deep a plurality of support protrusion 52 of this plate body 51 2 and 53, these support protrusion 52,53 against the base plate 11 of lower house 10 and the top board 21 of upper shell 20, increase the structural strength of whole temperature-uniforming plate 1 with this respectively.
With reference to figure 6, after temperature-uniforming plate 1 of the present invention completes assembling and welding, by gas removing pipe 13, temperature-uniforming plate 1 inside can be evacuated, last the more exposed one section of mode with welding or pressing of gas removing pipe 13 is sealed.
With reference to figure 7, it shows another embodiment of the present invention, the difference of the present embodiment and previous embodiment is: the temperature-uniforming plate 1 of previous embodiment is in the form of annular discs, and the temperature-uniforming plate 1' of the present embodiment is square, and gas removing pipe 13' is arranged on a wherein corner of this square structure.Although the lower house 10 of temperature-uniforming plate 1' and upper shell 20 make into squarely in this embodiment, the periphery of upper shell 20 is still provided with an annular groove 22, and jointly surrounds a scolder accommodating area Z with the lower side panel 12 of lower house 10, uses for scolder 100 and is undertaken in wherein.
The present invention also provides a kind of method of manufacturing temperature-uniforming plate, comprises following steps:
(a) moulding one lower house 10, this lower house 10 has a base plate 11 and extends a lower side panel 12 of these base plate 11 peripheries, and this base plate 11 surperficial sintering upward has a capillary structure (that is: lower capillary portion 31);
(b) moulding one upper shell 20, this upper shell 20 has a top board 21, take shape in an annular groove 22 of these top board 21 outer rims and extend an epipleural 23 of these annular groove 22 peripheries, and the inwall sintering of this upper shell 20 has another capillary structure (that is: upper capillary portion 32);
(c) by a working fluid 40 (for example: water) inject this lower house 10 inside;
(d) by these upper shell 20 cover caps in this lower house 10 so that this epipleural 23 supports, paste this lower side panel 12, and make to surround between this annular groove 22 and this lower side panel 12 a scolder accommodating area Z;
(e) scolder 100 is coated with and is welded in the Z of this scolder accommodating area, with soldering and sealing, live this upper shell 20 and this lower house 10;
(f) by a gas removing pipe 13, the space between this lower house 10 and this upper shell 20 is evacuated; And
(g) seal this gas removing pipe 13.
In addition, between step (b) and step (c), can optionally set up a step (b'): a supporting construction 50 is arranged between this lower house 10 and this upper shell 20.As shown in Figure 1, this supporting construction 50 is in order to be supported between the base plate 11 of lower house 10 and the top board 21 of upper shell 20, to prevent that base plate 11 from making whole temperature-uniforming plate 1 depression go down because of ambient pressure or external force with top board 21.Supporting construction 50 comprises a plate body 51 and protrudes from the lip-deep a plurality of support protrusion 52 of this plate body 51 2 and 53, these support protrusion 52 and 53 against the base plate 11 of lower house 10 and the top board 21 of upper shell 20, increase the structural strength of whole temperature-uniforming plate 1 with this respectively.
Compared to prior art, the present invention has following beneficial effect: because temperature-uniforming plate 1 of the present invention has a lower house 10 and a upper shell 20, and top board 21 peripheries of upper shell 20 form an annular groove 22, when upper shell 20 cover caps are during in lower house 10, between the annular groove 22 of upper shell 20 and the lower side panel 12 of lower house 10, be enclosed to form a scolder accommodating area Z.By this structure, when upper shell 20 and lower house 10 are welded together, scolder 100 splashes in the Z of scolder accommodating area and is undertaken in the Z of scolder accommodating area from the top of upper shell 20, so scolder 100 can not drop onto on temperature-uniforming plate 1 working top around, make the working environment of production line keep clean.
In addition, because scolder 100 is undertaken in the Z of scolder accommodating area, so the scolder 100 after hardening by cooling can firmly be undertaken in the Z of scolder accommodating area, and be subject to lower side panel 121 bracketings of lower house 10 and incrust, contribute to maintain the sealing effectiveness of weld strength and temperature-uniforming plate 1.
The above embodiment is only the preferred embodiment for absolutely proving that the present invention lifts, and protection scope of the present invention is not limited to this.Being equal to that those skilled in the art do on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
