The present invention relates in general to a configuring apparatus and a processing method for a thermal conductive plate, and more particular, to a method using high-temperature fusion to seal individual plates of a thermal conductive plate.
The conventional thermal conductive plate includes a top plate and a bottom plate laminated together to form a thin hollow shell. A wick structure and a working fluid are introduced within the shell, and the joint between the top plate and the bottom plate is sealed by brazing. A vacuum step is performed between the brazing step. However, the brazing step results in poor sealing effect of the thermal conductive plate, so that the yield is typically poor. Further, the cost for fabricating this type of thermal conductive plate is high.
To resolve the problems caused by the conventional thermal conductive plate as described above, the Applicant, with many years of experience in this field, has developed a configuring apparatus and a processing method for a thermal conductive plate as described as follows.
The present invention provides a configuring apparatus and a processing method for a thermal conductive plate. High-temperature fusion is applied to seal the thermal conductive plate, such that the yield is enhanced, and the fabrication is speeded up to aid in automatic execution.
The configuring apparatus provide by the present invention includes a working platform, a first and a second lamination units and a movable fusion head. The working platform includes a positioning seat for holding the thermal conductive plate. The first and second lamination units are disposed at two sides of the positioning seat for pressing the thermal conductive plate on the positioning seat. The fusion head is located over the positioning seat to seal the thermal conductive plate by high-temperature fusion.
The processing method provided by the present invention includes performing high-temperature fusion on joint of individual plates of the thermal conductive plate.
These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of preferred embodiments.
It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.
These as well as other features of the present invention will become more apparent upon reference to the drawings therein:
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Referring to
The working platform 1 is used to carry the above elements, such that each of the first and second laminating units 2 and 3 and the moveable fusion head 4 are disposed thereon to perform sealing operation of the thermal conductive plate 5. The working platform 1 includes a positioning seat 10 in which the thermal conductive plate 5 is disposed. The positioning seat 10 includes a recessed slot 100 for receiving the thermal conductive plate 5 therein and a moving unit 101 underneath the recessed slot 100. The moving unit 101 is operative to push the thermal conductive plate 5 upwardly, such that the thermal conductive plate 5 can be easily removed from the positioning seat 10.
A box member 11 can be disposed under the working platform 1. The box member 11 includes a heat circulating and dissipating system 110. The heat circulating and dissipating system 10 circulate and dissipate heat by cooling liquid. Large size dissipating fan may also be used to dissipate the heat by air. During the sealing operation of the thermal conductive plate 5, individual plates of the thermal conductive plate 5 is joined and sealed by high-temperature fusion, such that the heat circulating and dissipating system 10 is particularly design for heat exchange to reduce the temperature of the thermal conductive plate 5. The positioning seat 10 is preferably fabricated from material with good conductivity such as copper. Therefore, the heat of the thermal conductive plate 5 can thus be conducted towards the positioning seat 10 easily to be dissipated.
The first laminating unit 2 and the second laminating unit 3 are placed at left and right sides of the positioning seat 10, respectively. The first and second laminating units 2 and 3 each comprise the rotation seats 20 and 30 mounted to the working platform 1. Suspending arms 21 and 31 connected to the rotation seats 20 and 30 are driven thereby, respectively. Lamination members 22 and 32 are formed at free ends of the suspending arms 21 and 31. When the thermal conductive plate 5 is disposed in the recessed slot 100 of the positioning seat 10, the lamination members 22 and 32 stably press the thermal conductive plate 5 on the positioning seat 10 to perform sealing operation thereon.
The moveable fusion head 4 is located over the positioning seat 100. The moveable fusion head 4 is supported by a coordinate mechanism 40 on the working platform 1. The coordinate mechanism 40 includes an X-slide track 41, a Y-slide track 42 and a Z-slide track 43, such that the fusion head 4 can displace along the X-axis, Y-axis and Z-axis as required. When a predetermined path is configured, the fusion head 4 is controlled by the coordinate mechanism 40 along the predetermined path to reach a specific location.
In addition, an enclosure 12 may be used for masking the first laminating unit 2, the second laminating unit 3 and the fusion head 4. A transparent window 120 may be formed in the enclosure 12 for monitoring the operation status inside of the enclosure 12.

As shown in
Thereby, a configuring apparatus for a thermal conductive plate is obtained.
The present invention further comprises a processing method for configuring a thermal conductive plate. In the conventional fabrication of a thermal conductive plate 5, the processes of cleaning the raw material, disposing copper powder into a plate member, forming capillary structure by high-temperature sintering the powder, assembling the plate, sealing the plate, installing exhaust pipe, soldering the soldering material, high temperature recovery, quality adjustment, filling working fluid, vacuuming, and sealing brazing are required. By this invention, the sealing operation is performed by high-temperature fusion, and therefore, several processes can be eliminated.
While an illustrative and presently preferred embodiment of the invention has been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
