Description

Turbulent flow structure of temperature equalizing plate

Technical Field

The present invention relates to a heat conduction assembly, and more particularly to a turbulent flow structure of a temperature equalizing plate.

Background

The prior temperature equalizing plate not only provides heat transfer function by contacting one surface with a heat source and condensing the other surface, but also has various shapes matched with different heat dissipation requirements. For example, by using a design similar to a Heat Pipe (Heat Pipe), a part of the temperature equalization plate is heated, a part of the temperature equalization plate is condensed, and then the transmission shape is provided according to the difference between the Heat source and the Heat dissipation position, so as to form the temperature equalization plate with various shapes, thereby meeting the requirements that the temperature equalization plate is suitable for various application environments and the like.

However, practical use may be faced with problems, such as being limited by the required changes in shape, and may also affect the function or performance of the thermal plate. As is well known, the vapor-liquid phase change of the working fluid sealed inside the vapor-liquid phase change plate provides heat transfer function; when the vapor-phase or liquid-phase working fluid is transmitted, the transmitted flow rate can be influenced by the change of the shape of the temperature-equalizing plate, for example, when the sectional area of the temperature-equalizing plate is reduced from large to small, the flow rate of the passing working fluid is accelerated to generate change. If the vaporized working fluid is accelerated, the returned liquid working fluid is affected, and even cannot be returned, which causes the so-called dry burning problem. Therefore, how to avoid the problem is one of the important issues in the design of the current temperature equalizing plate.

Detailed Description

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

Please refer to fig. 1, fig. 2 and fig. 3, which are an exploded view, an assembled view and a plan view of the internal structure of the first embodiment of the present invention. The utility model provides a turbulent flow structure of a uniform temperature plate, wherein the uniform temperature plate 1 comprises a lower plate body 10 and an upper plate body 11 which are mutually covered to form a hollow interior, and a capillary layer 12 is covered in the lower plate body 10. The wicking layer 12 may be a woven mesh, sintered powder, or grooves formed in the lower plate 10.

As mentioned above, the lower plate 10 and the upper plate 11 of the vapor chamber 1 together form an evaporation portion a and a condensation portion B, that is, the lower plate 10 has a lower evaporation portion 100 corresponding to the evaporation portion a and a lower condensation portion 101 corresponding to the condensation portion B, the upper plate 11 also has an upper evaporation portion 110 corresponding to the evaporation portion a and an upper condensation portion 111 corresponding to the condensation portion B, and the area of the evaporation portion a can be larger than that of the condensation portion B. The vapor chamber 1 has a transmission part C between the evaporation part a and the condensation part B, i.e. the lower plate 10 has a lower transmission part 102 corresponding to the transmission part C, and the upper plate 11 has an upper transmission part 112 corresponding to the transmission part C. 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 that of the condensation part B.

As shown in fig. 3, the present invention mainly has a turbulent structure in the transmission part C to prevent the transmission part C from the evaporation part a to the condensation part B in a tapered shape from generating an acceleration phenomenon when the vaporized working fluid passes through, thereby affecting the reflux speed and reflux amount of the liquid working fluid and further preventing the dry burning problem. The transmission part C is provided with the turbulence structure, the turbulence structure is specifically composed of a plurality of turbulence columns 13 supported between the lower plate body 10 and the upper plate body 11, and at least comprises a plurality of first columns 130 adjacent to one end of the evaporation part a and a plurality of second columns 131 adjacent to one end of the condensation part, and the arrangement distance D between the first columns 130 is smaller than the arrangement distance D between the second columns 131. Secondly, a plurality of third columns 132 may be disposed between the first column 130 and the second column 131 in the transmission part C, and each third column 132 may be arranged from the first column 130 to the second column 131 to be distributed in the transmission part C to maintain the turbulent flow effect.

Accordingly, as shown in fig. 4, the evaporation portion a of the vapor chamber 1 can be used as a heat source 2, and the condensation portion 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 is vaporized and then directed to the condensation part B, and at this time, since the arrangement distance d of the first columns 130 is the minimum, a turbulent flow effect can be provided to avoid the phenomenon of acceleration of the vaporized working fluid. Next, as shown in fig. 5, the vaporized working fluid passing through the transfer portion C is gradually slowed down by the influence of the turbulent structure, and when finally passing through the second columns 131, since the arrangement distance D of the second columns 131 is the largest, the vaporized working fluid after passing through can smoothly enter the condensation portion B for cooling. Meanwhile, the working fluid which is returned to the liquid state in the condensation part B flows back through the capillary layer 12 in the lower plate body 10, and the vaporized working fluid in the transmission part C cannot be accelerated due to the turbulent flow structure, so that the proper capillary force can be maintained through the capillary layer 12 and quickly flows back to the evaporation part A, and the dry burning problem is avoided.

Referring to fig. 1 and 2, in the present invention, a plurality of supporting columns 14 are disposed in the upper evaporation portion 110 and the upper condensation portion 111 of the evaporation portion a and the condensation portion B, and although the supporting columns 14 are also used for supporting the space between the lower plate 10 and the upper plate 11, the number of the supporting columns 14 is not limited by the above-mentioned distance because the turbulent flow problem is not considered, and the number of the supporting columns can be configured according to the area of the actual evaporation portion a and the actual condensation portion B; in general, the support posts 14 are distributed in a looser or broader density than the turbulence posts 13.

Therefore, by means of the above structure, the turbulent flow structure of the temperature-uniforming plate of the present invention can be obtained.

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 a plurality of heat sources 2 through evaporation portions a with different shapes, meanwhile, condensation portions B can be added according to available condensation positions, and a transmission portion C is provided between each condensation portion B and the evaporation portion a, the design of the shape can be configured according to the actual heat source 2 and the heat dissipation position, and only in the transmission portion C, the flow-disturbing structure of the present invention can be designed to reduce or avoid the phenomenon of acceleration of the vaporized working fluid during transmission to affect the backflow effect, avoid the problem of dry burning, so that the temperature-equalizing plate 1 can still change its shape design according to the actual environmental requirements to meet the requirement of diversified environmental changes.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the utility model is all within the protection scope of the utility model. The protection scope of the utility model is subject to the claims.
