Description

Technical Field

[0001] This invention relates to a heat conduction and heat dissipation element, and more particularly to a flexible plastic heat plate structure. Background Technology

[0002] Modern hot plates are mainly composed of two plates stacked on top of each other. Due to the vacuum inside, a supporting structure must be installed between the two plates to maintain the internal chamber space for the sealed working fluid to undergo phase change.

[0003] However, when the hot plate is formed in a curved shape, the supporting structure in the curved part is prone to being unable to effectively support the two plates at the bend due to the curved shape. This may even cause a depression between the two plates at the bend, affecting the formation of the internal cavity. This will result in a significant reduction in the heat transfer performance of the hot plate.

[0004] In view of this, the inventors, in order to improve and solve the above-mentioned deficiencies, have devoted themselves to research and applied theoretical principles, and finally proposed an invention that is rationally designed and effectively improves the above-mentioned deficiencies. Summary of the Invention

[0005] The main objective of this invention is to provide a flexible, moldable hot plate structure that, through a long strip integrally formed with one of the plates, constitutes the required support structure at the bending part of the hot plate, thereby avoiding or reducing the attenuation of heat transfer performance caused by dents.

[0006] To achieve the above objectives, the present invention provides a flexible hot plate structure, comprising an inner curved plate, an outer curved plate, and a capillary structure; the inner curved plate has an inner recess and an inner sealing edge around the periphery of the inner recess, and the inner curved plate has a first inner plate segment, a second inner plate segment, and an inner curved segment connecting the first inner plate segment and the second inner plate segment; the outer curved plate is stacked on top of the inner curved plate and has an outer recess opposite to it, and an outer sealing edge around the periphery of the outer recess, and the outer curved plate has a first outer plate segment, a second outer plate segment, and an outer curved segment connecting the first outer plate segment and the second outer plate segment; the capillary structure is attached to the inner recess of the inner curved plate; wherein, at least one strip-shaped support structure is integrally formed on the outer recess of the outer curved plate, the strip-shaped support structure is located within the outer curved segment and extends toward the first outer plate segment and the second outer plate segment respectively, and abuts against the inner curved segment of the inner curved plate.

[0035] To further illustrate the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit the present invention.

[0036] Please see Figure 1 , Figure 2 and Figure 3 The figures shown are an exploded perspective view, an exploded perspective view from another angle, and a three-dimensional assembly diagram of the present invention. The present invention provides a flexible, moldable hot plate structure, comprising an inner bent plate 1, an outer bent plate 2, and a capillary structure 3; wherein:

[0037] The inner-bent plate 1 can be made of a material with good thermal conductivity, such as copper or aluminum, and is formed by bending to form the inner side of the plate after the hot plate is bent. The inner-bent plate 1 has a recessed portion 10 on the outer surface of the bent portion, and an inner sealing edge 100 is provided around the recessed portion 10. In addition, the inner-bent plate 1 has a first inner plate segment 11, a second inner plate segment 12, and an inner-bent segment 13 connecting the first inner plate segment 11 and the second inner plate segment 12 after bending.

[0038] The outer curved plate 2 can also be made of a material with good thermal conductivity, such as copper or aluminum, and is formed by bending to form the outer part of the plate body after the hot plate is bent. The outer curved plate 2 has an outer recess 20 on the inner surface of the bent plate, and an outer sealing edge 200 is provided around the outer recess 20. In the embodiment of the present invention, the outer sealing edge 200 has an inner edge 201 and an outer edge 202, and a solder groove 203 formed between the inner edge 201 and the outer edge 202. Solder is filled in the solder groove 203 to seal the inner sealing edge 100 and the outer sealing edge 200. In addition, the outer curved plate 2 has a first outer plate segment 21, a second outer plate segment 22, and an outer curved segment 23 connecting the first outer plate segment 21 and the second outer plate segment 22 after bending.

[0039] like Figure 4 and Figure 4A As shown, the inner curved plate 1 and the outer curved plate 2 are stacked on top of each other according to their inner and outer relationships, and the inner sealing edge 100 and the outer sealing edge 200 are sealed together by stacking as described above. Please refer to the following: Figure 1 , Figure 2 and Figure 5As shown, the capillary structure 3 is attached to the recessed portion 10 of the inner curved plate 1. In the embodiment of the present invention, the capillary structure 3 may be composed of a layered capillary 30 and a strip capillary 31. The layered capillary 30 extends from the first inner plate segment 11 of the inner curved plate 1 through the inner curved segment 13 to the second inner plate segment 12, so as to completely cover the recessed portion 10. The strip capillary 31 is stacked on the layered capillary 30 and extends at least through the inner curved segment 13 and into the first inner plate segment 11 and the second inner plate segment 12, respectively.

[0040] Please see again Figure 1 and Figure 2 As shown, the present invention mainly comprises at least one strip-shaped support structure 230, a plurality of first support columns 210, and a plurality of second support columns 220 integrally formed on the outer concave portion 20 of the outer curved plate 2. The strip-shaped support structure 230 is located within the outer curved section 23 and extends toward the first outer plate section 21 and the second outer plate section 22, respectively. The first support columns 210 are distributed within the first outer plate section 21 and can be arranged in one or more rows at intervals along one end of the strip-shaped support structure 230 toward the first outer plate section 21; and the second support columns 220 are distributed within the second outer plate section 22 and can also be arranged in one or more rows at intervals along one end of the strip-shaped support structure 230 toward the second outer plate section 22. Specifically, the cross-sections of the first support columns 210 and the second support columns 220 can have any geometric shape, such as cylindrical or elongated columnar.

[0041] Therefore, the flexible hot plate structure of the present invention can be obtained by the above-described structural composition.

[0042] Accordingly, Figure 4 and Figure 4AAs shown, the present invention utilizes the strip-shaped support structure 230 integrally formed on the outer recess 20 of the outer curved plate 2. This provides the necessary strength for mutual support between the inner curved section 13 and the outer curved section 23, allowing the outer curved section 23 to push against the inner curved section 13, thus avoiding or reducing depressions caused by bending and effectively preventing attenuation or loss of heat transfer performance of the hot plate due to depressions. Furthermore, the first support column 210 provides support strength between the first inner plate section 11 and the first outer plate section 21, while the second support column 220 provides support strength between the second inner plate section 12 and the second outer plate section 22. Both can also be integrally formed on the outer recess 20 of the outer curved plate 2. The integral molding method can be achieved by etching the outer recess 20 on the outer curved plate 2 using etching technology, while reserving the strip-shaped support structure 230, the first support columns 210 and the second support columns 220, or by stamping the outer recess 20 on the outer curved plate 2 using stamping technology, while making the strip-shaped support structure 230, the first support columns 210 and the second support columns 220 protrude and form within the outer recess 20.

[0043] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the claims of the present invention.
