Description

Technical Field

[0001] This case concerns a vapor chamber, particularly a vapor chamber product without a degassing tube. Background Technology

[0002] Currently, most heat spreader manufacturing processes require the installation of injection pipes (or degassing pipes) to inject working fluid and perform degassing or vacuuming. Subsequent edge welding and sealing are then performed to form the heat spreader. However, the inclusion of injection pipes not only increases production complexity and cost but may also occupy additional space, thus hindering the design of thinner heat spreaders.

[0003] Furthermore, most vapor chambers have internal support structures. These structures provide sufficient support for the internal space of the vapor chamber, preventing deformation or damage during manufacturing or use. In addition, a well-designed internal support structure helps to distribute heat evenly, preventing localized overheating and thus improving the heat dissipation performance of the vapor chamber. However, the design and manufacturing of these support structures require sophisticated technology, thus increasing the complexity and cost of the manufacturing process.

[0004] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Utility Model Content

[0005] One objective of this invention is to provide a vapor chamber product that does not have an injection pipe, thereby reducing the complexity and cost of production and not occupying additional space, which facilitates the thin design of the vapor chamber.

[0006] One objective of this invention is to provide a vapor chamber product in which a support structure is formed by 3D printing and sintering, thereby providing sufficient support for the internal space of the vapor chamber and preventing deformation or damage during manufacturing or use, thereby maintaining the structural integrity and stability of the vapor chamber.

[0007] To achieve the aforementioned objectives, this invention relates to a vapor chamber product comprising a stainless steel shell, a capillary structure, a support structure, and a working fluid. The stainless steel shell has a cavity and includes a roughened surface facing the cavity. The capillary structure is disposed on the roughened surface. The support structure is positioned within the cavity and includes layers formed by 3D printing and sintering, and multiple protrusions stacked and printed on the layers, the protrusions being spaced apart on opposite sides of the layers. The working fluid is injected into the cavity.

[0008] In one embodiment of this invention, the stainless steel housing includes a base plate, a frame, and a cover plate, and the walls of the cavity are roughened by laser on the surfaces of the base plate and the cover plate.

[0009] In one embodiment of this case, the capillary structure is formed by 3D laser sintering and printing stainless steel powder, and the thickness of the capillary structure is not less than 0.01 mm and not more than 0.1 mm.

[0010] In one embodiment of this case, the support structure includes a shelf and a plurality of protrusions, the support structure being arranged on opposite sides of the shelf with an average of 25 to 30 protrusions per square centimeter.

[0011] In one embodiment of this case, each protrusion is a hollow cone, and a protrusion on one side of the shelf connects to an adjacent protrusion on the other side.

[0012] In one embodiment of this invention, the working fluid is a support structure injected into the cavity.

[0013] In one embodiment of this case, the stainless steel housing is sealed by laser welding.

[0014] Compared to conventional methods, the vapor chamber in this invention involves roughening the inner wall of a stainless steel shell and forming a capillary structure on the roughened surface. A support structure is then formed using 3D printing and sintering. The semi-finished vapor chamber is then vacuum-sealed and laser-welded within a sealed cavity to produce the vapor chamber. Because the vapor chamber in this invention does not have an injection tube, production complexity and cost are reduced. Furthermore, eliminating the injection tube facilitates a thinner design for the vapor chamber. Additionally, the use of 3D printing and sintering to form the support structure reduces production complexity and cost, and does not occupy additional space, further facilitating a thinner design. Moreover, the 3D printing and sintering method used to form the internal support structure simplifies the design and manufacturing process, reducing manufacturing complexity and cost.

After the working fluid 30 is injected into the cavity 100, the cover plate 13 is placed on the frame 12 to seal the cavity 100.

[0031] Please refer to again Figure 6 This is a schematic diagram of the vacuuming process in the manufacturing method of the heat spreader in this case, and it is accompanied by... Figure 1 The method for manufacturing a heat spreader is described below. The method for manufacturing a heat spreader in this invention further includes step f), providing a sealed cavity 60 and placing a stainless steel shell 10, on which the support structure 20 is provided, into the sealed cavity 60. The stainless steel shell 10 is placed on a processing table 40 and is subjected to pressure from a fixture 50. Furthermore, the method for manufacturing a heat spreader in this invention includes step g), using a vacuum device 70 to evacuate the sealed cavity 60, creating a vacuum state in the sealed cavity 60 and the cavity 100 of the stainless steel shell 10.

[0032] It should be noted that the vacuum device 70 can be a vacuum pump, used to connect to the sealed cavity 60 and evacuate the sealed cavity 60. Furthermore, in the vacuum operation of step g), the sealed cavity 60 is operated at a temperature below the boiling point of the working fluid 30.

Figure 1 The method for manufacturing a heat spreader is described below. The method further includes step h), sealing the stainless steel housing 10. In this invention, the support structure 20 is positioned by laser welding the surface of the stainless steel housing 10. Furthermore, the base plate 11, the frame 12, and the cover plate 13 are joined by laser welding the periphery of the stainless steel housing 10, thereby maintaining the vacuum and sealing of the cavity 100 and completing the heat spreader product.

[0034] Please refer to Figure 8 This is a three-dimensional schematic diagram of the vapor chamber product of this case. In this case, vapor chamber product 1 was manufactured according to the aforementioned vapor chamber manufacturing method. Since the vapor chamber product 1 does not use a filling tube (degassing tube) in the manufacturing method, no filling tube (degassing tube) or post-processing marks are visible on the appearance of the finished product.

[0035] Please refer to again Figure 9 This is a combined cross-sectional view of the vapor chamber product of this invention. The vapor chamber product 1 of this invention includes a stainless steel housing 10, a capillary structure 14, a support structure 20, and a working fluid 30. The stainless steel housing 10 has a cavity 100, and the stainless steel housing 10 includes a rough surface 101 facing the cavity.

[0036] Furthermore, the support structure 20 is positioned within the cavity 100. The support structure 20 includes a layer 21 formed by 3D printing and sintering, and a plurality of protrusions 22 stacked and printed on the layer 21. These protrusions 22 are spaced apart on opposite sides of the layer 21. Additionally, the working fluid 30 is injected into the cavity 100.

[0037] Specifically, the stainless steel housing 10 includes a base plate 11, a frame 12, and a cover plate 13. The support structure 20 includes a shelf 21 and a plurality of protrusions 22. Each protrusion 22 is a hollow cone, and a protrusion 22 on one side of the shelf 21 connects to an adjacent protrusion 22 on the other side. The protrusion 22 on one side of the support structure 20 abuts against the base plate 11, while the protrusion 22 on the other side abuts against the cover plate 13.

[0038] Accordingly, the vapor chamber plate product 1 of this invention does not have an injection pipe, which reduces the complexity and cost of production and does not occupy additional space, thus facilitating the thinner design of the vapor chamber plate. In addition, this invention uses 3D printing sintering to form the internal support structure, thereby simplifying the design and manufacturing process of the support structure and reducing the complexity and cost of the manufacturing process.
