Vapor chamber spoiler structure

This creation is related to a thermally conductive element, especially a vapor chamber spoiler structure.

According to this, in addition to providing heat transfer through one surface of the vapor chamber contacting the heat source and the other surface acting as condensation, the existing vapor chambers are also designed in various shapes to suit different heat dissipation requirements. For example, through the design similar to the heat pipe (Heat Pipe), part of the vapor chamber is used as heating and part as condensation, and then depending on the difference between the heat source and the heat dissipation position, the intermediate transmission shape is provided, so as to form various shapes of vapor chambers to meet the needs of Vapor chambers are suitable for changing application environments and other needs.

However, there may be some problems in practical use, such as being limited by the required changes in shape, which may also affect the function or performance of the vapor chamber. As we all know, the vapor chamber provides heat transfer by producing vapor-liquid phase changes in the working fluid stored in it; and when the vapor or liquid working fluid is transported, it is possible to face changes in the shape of the vapor chamber. The flow velocity that affects its transmission, such as the cross-sectional area of the temperature equalizing plate changes from large to small, the flow velocity of the passing working fluid will be accelerated and changed. If the vaporized working fluid is accelerated, the backflowing liquid working fluid will be affected, and even cannot be backflowed, resulting in the so-called "dry burning" problem. Therefore, how to avoid this problem is one of the important issues in the design of vapor chambers today.

In view of this, in order to improve and solve the above-mentioned deficiencies, the author of this book has devoted himself to research and the application of academic principles, and finally proposed a book with a reasonable design and effective improvement of the above deficiencies.

Affect its function or efficiency of heat transfer.

In order to achieve the above-mentioned purpose, the present invention provides a temperature-spreading plate turbulence structure, which includes a lower plate body and an upper plate body overlapping with each other to form an inner hollow shape, and has a joint formed by the lower plate body and the upper plate body. The evaporation part, a condensation part, and a transmission part communicated between the evaporation part and the condensation part; wherein, the transmission part is provided with a plurality of spoiler columns supported between the lower plate body and the upper plate body, and the spoiler columns At least it includes a plurality of first cylinders adjacent to one end of the evaporation part and a plurality of second cylinders adjacent to one end of the condensation part, and the arrangement spacing between the first cylinders is smaller than the distance between the second cylinders. Arrange spacing.

In order to enable your reviewers to further understand the features and technical content of this creation, please refer to the following detailed descriptions and drawings about this creation, however, the attached drawings are only for reference and illustration, and are not intended to limit this creation. .

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are a perspective exploded view, a three-dimensional combined schematic view, and a plan view of the internal structure of the first embodiment of the present invention, respectively. The present invention provides a temperature-spreading plate turbulence structure. The temperature-spreading plate 1 includes a lower plate body 10 and an upper plate body 11 that are covered with each other to form a hollow interior, and the lower plate body 10 is covered with a capillary layer 12. The capillary layer 12 may be woven mesh, sintered powder or grooves formed in the lower plate body 10 .

Based on the above, the lower plate body 10 and the upper plate body 11 of the temperature equalizing plate 1 together form an evaporation part A and a condensation part B, that is, the lower plate body 10 has a lower evaporation part 100 corresponding to the evaporation part A and a condensation part B. A lower condensing part 101 corresponding to the condensing part B, and the upper plate body 11 also has an upper evaporating part 110 corresponding to the evaporating part A and an upper condensing part 111 corresponding to the condensing part B, and the area of the evaporating part A can be larger than that of the condensing part area of B. Between the evaporation part A and the condensation part B of the temperature equalizing plate 1, there is a transmission part C connected between the evaporation part A and the condensation part B, that is, the lower plate body 10 has a lower transmission part corresponding to the transmission part C The upper plate body 11 has an upper transmission part 112 corresponding to the transmission part C. And the transmission part C is tapered from the evaporation part A to the condensation part B, so that the area of the evaporation part A is larger than the area of the condensation part B.

As shown in Fig. 3, the present invention is mainly based on the fact that the above-mentioned transmission part C is provided with a turbulent flow structure to prevent the transmission part C that is tapered from the evaporation part A to the condensing part B, resulting in the acceleration of the vaporized working fluid when passing through. phenomenon, thus affecting the recirculation speed and recirculation amount of the liquid working fluid, thereby preventing the dry burning problem. Wherein, the transmission part C is provided with the spoiler structure, and the spoiler structure is specifically composed of a plurality of spoiler columns 13 supported between the lower plate body 10 and the upper plate body 11 , and at least includes adjacent evaporation columns 13 . A plurality of first cylinders 130 at one end of the part A and a plurality of second cylinders 131 at one end adjacent to the condensation part, and the arrangement spacing d between the first cylinders 130 is smaller than the second cylinders 131 The arrangement spacing D between each other. Next, between the first cylinder 130 and the second cylinder 131 in the transmission portion C, a plurality of third cylinders 132 can also be provided, and each third cylinder 132 can be arranged from the first cylinder 130 to The second pillars 131 are distributed in the transmission portion C to maintain the turbulence effect.

Accordingly, as shown in FIG. 4 , the evaporation part A of the temperature equalizing plate 1 can be used on a heat source 2 , and the condensation part B can be provided with a plurality of fins 3 for heat dissipation. When the evaporation part A is heated by the heat source 2, the working fluid inside the temperature equalizing plate 1 will be vaporized and will face the condensation part B. At this time, since the arrangement spacing d of the first cylinders 130 is the smallest, the turbulence effect can be provided. And avoid the accelerated phenomenon of the vaporized working fluid. Next, as shown in FIG. 5 , the vaporized working fluid passing through the transmission portion C will be continuously affected by the turbulence structure and gradually slow down the flow rate. D is the largest, so the vaporized working fluid after passing can be smoothly entered into the condensation part B for cooling. At the same time, since the working fluid returned to liquid state in the condensing part B, the system will flow back through the capillary layer 12 located in the lower plate body 10, and the vaporized working fluid in the transmission part C will not occur due to the turbulent structure. Therefore, the capillary layer 12 can pass through the capillary layer 12 to maintain its proper capillary force and quickly return to the evaporation part A, thereby avoiding the occurrence of the dry burning problem.

Please refer to FIG. 1 and FIG. 2 again, the present invention is provided with a plurality of support columns 14 in the upper evaporation part 110 and the upper condensation part 111 of the evaporation part A and the condensation part B, although the support columns 14 are also used for The space between the lower plate body 10 and the upper plate body 11 is supported, but because the turbulence problem is not considered and there is no restriction on the distance between each other as mentioned above, the corresponding number can be configured according to the actual area of the evaporation part A and the condensation part B; generally, the In other words, the distribution density of the support pillars 14 will be looser or wider than the density of the aforementioned spoiler pillars 13 .

Therefore, through the above-mentioned structure composition, the present invention can be obtained with the air-spreading plate spoiler structure.

In addition, as shown in FIG. 6 , in the second embodiment of the present invention, the temperature equalizing plate 1 can correspond to different heat sources 2 or multiple heat sources 2 through evaporation parts A of different shapes. Condensing part B is added at the same location, and there is a transmission part C between each condensing part B and evaporating part A. The design of its shape can be configured according to the actual heat source 2 and heat dissipation position, only in the transmission part C Through the design of the turbulent structure in this creation, the acceleration phenomenon of the vaporized working fluid during transmission can be reduced or avoided to affect the reflux effect, and the problem of dry burning can be avoided, so that the uniform temperature plate 1 can still be changed according to the actual environment.
