Description

Technical Field

[0001] This utility model relates to the field of heat spreader technology, specifically to a novel heat spreader structure. Background Technology

[0002] A vapor chamber is a vacuum chamber with a finely structured inner wall, typically made of copper, and is commonly used in electronic products that require small size or rapid heat dissipation. Its working principle is similar to a flat-plate heat pipe: heat is conducted to the evaporation zone, where the coolant rapidly vaporizes and expands, filling the chamber with gaseous cooling medium. Upon contact with the cold zone, the cooling medium condenses and releases heat, circulating back to the heat source through fine channels. However, its structure is flatter, resulting in a larger heat dissipation area.

[0003] Due to the thinness of its heat spreader and the structure of its internal vacuum chamber, the upper and lower cover plates are prone to "bulging" or "sinking" under high temperature or high pressure differential due to internal steam flow or external stress. This can lead to changes in the height of the internal capillary structure and even poor local contact, affecting its heat transfer performance. Utility Model Content

[0004] (I) Technical problems to be solved The technical problem to be solved by this utility model is to overcome the defects of insufficient stability of the above-mentioned heat spreader structure and its inability to effectively resist deformation, and to provide a new type of heat spreader structure.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a novel heat spreader structure, including a base plate and a top cover, wherein a plurality of arrayed support columns are provided on the inner surface of the top cover, and a plurality of support frames are provided on the base plate, wherein the support frames and support columns are arranged vertically and vertically respectively, and the center of the support frame is provided with an insertion hole matching the support column. A plurality of support plates I are provided at equal intervals on both sides of the top cover, and support plates II are provided on both sides of the base plate, which are staggered with the support plates I. The support plates II are snapped into the grooves formed by the two support plates I.

[0006] As an improvement: the support frame is a trapezoidal structure, the size of the end of the support frame connected to the base plate is larger than the size of the end away from the base plate, and a corrugated pipe is connected to the support frame, one end of which is connected to the base plate, and the corrugated pipe is made of copper.

[0007] As an improvement: a copper mesh is provided between the base plate and the top cover, and a number of perforations are arranged in an array on the copper mesh. The perforations correspond one-to-one with the support frame, and the size of the perforations is the same as the maximum cross-sectional size of the support frame.

[0008] As an improvement: both support plate one and support plate two are isosceles triangular structures, and both support plate one and support plate two are made of copper.

[0009] As an improvement: the base plate, top cover, support column, and support frame are all made of copper.

[0010] (III) Beneficial Effects The advantages of this utility model compared with the prior art are as follows: By inserting the support column into the socket of the support frame, the two form a rigid connection, which can distribute the pressure and stress during use and reduce the probability of deformation. At the same time, the support plate one and support plate two are interlocked to form a three-dimensional support frame, thereby effectively improving the stability of the structure, reducing the risk of misalignment, and ensuring its heat dissipation performance.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0017] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagrams, while the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] To improve the heat spreader's resistance to deformation and enhance structural stability during use, combined with... Figure 1 , Figure 2 and Figure 4As shown, a novel heat spreader structure includes a base plate 1 and an upper cover 2. The inner surface of the upper cover 2 is provided with a plurality of arrayed support columns 3. The base plate 1 is provided with a plurality of support frames 4, which are arranged vertically and vertically corresponding to the support columns 3. The center of the support frame 4 is provided with an insertion hole 5 that matches the support column 3. Among them, the combination of appendix Figure 2 and Figure 3 As shown, the support frame 4 has a trapezoidal structure. The size of the end of the support frame 4 connected to the base plate 1 is larger than the size of the end away from the base plate 1. A corrugated pipe 8 is connected to the support frame 4. One end of the corrugated pipe 8 is connected to the base plate 1. The corrugated pipe 8 is made of copper. The support frame 4 is trapezoidal in design, with its larger end facing the base plate 1 and its smaller end facing the top cover 2. The trapezoidal support frame 4 increases the stress area of ​​the base plate 1, disperses the pressure, and avoids local stress concentration. The design of the smaller end being close to the top cover 2 can reduce the obstruction to steam flow. The support columns 3 on the top cover 2 are inserted into the insertion holes 5 of the support frame 4 one by one, which improves the structural resistance to deformation. The corrugated pipe 8 made of copper has a certain degree of elasticity, which can prevent structural deformation caused by temperature difference or pressure and extend the service life of the heat spreader.

[0020] Combined with appendix Figure 2 and Figure 4 As shown, multiple support plates 6 are equidistantly arranged on both sides of the upper cover 2, and support plates 7 are provided on both sides of the bottom plate 1, which are staggered with the support plates 6. The support plates 7 are snapped into the slots formed by the two support plates 6. Both the support plates 6 and 7 are isosceles triangular structures, and both the support plates 6 and 7 are made of copper. The triangular structure is a geometrically stable shape. With the above arrangement, when the upper cover 2 and the bottom plate 1 are welded together, the support plate 6 and the support plate 7 are snapped together to form a stable structure. Under the combined action of the vacuum negative pressure inside the heat spreader and the external atmospheric pressure, when the upper cover 2 and the bottom plate 1 tend to move closer to each other, the triangular support plate 6 and the support plate 7 can effectively disperse the pressure, thereby preventing the heat spreader from bulging or denting.

[0021] Combined with appendix Figure 1 As shown, a copper mesh 9 is provided between the base plate 1 and the top cover 2. A plurality of perforations 10 are arrayed on the copper mesh 9. The perforations 10 correspond one-to-one with the support frame 4, and the size of the perforations 10 is the same as the maximum cross-sectional size of the support frame 4. The copper mesh 9 is laid between the upper cover 2 and the bottom plate 1. Since the copper mesh 9 itself has a capillary structure, it can promote liquid reflux and improve the heat dissipation uniformity of the heat exchange plate. The perforation 10 allows the support frame 4 to pass through the copper mesh 9, avoiding the increase of thermal resistance. Combined with appendix Figure 1As shown, the base plate 1, top cover 2, support column 3, and support frame 4 are all made of copper. The use of all-copper material and the capillary structure of copper mesh 9 ensures that the entire heat transfer path is made of the same high thermal conductivity material, minimizing the contact thermal resistance between different material interfaces and avoiding stress problems caused by the mismatch of thermal expansion and contraction of different materials. In addition, the copper material has a certain strength and hardness, which can provide a certain structural support for the heat spreader, thereby resisting external pressure and impact.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
