Description

Technical Field

[0001] This invention relates to a heat conduction component, and more particularly to a heat spreader structure. Background Technology

[0002] Existing vapor chambers, besides providing heat transfer by having one surface in contact with the heat source and the other surface for condensation, are also designed in various shapes to meet different heat dissipation requirements. For example, by using a design similar to a heat pipe, one part of the vapor chamber is used for heating and the other for condensation, and the intermediate transfer shape is provided depending on the location of the heat source and heat dissipation, thereby constructing vapor chambers of various shapes to meet the needs of vapor chambers for various application environments.

[0003] However, practical applications may encounter some problems. For example, the required shape variations can affect the function or performance of the vapor chamber. As is well known, vapor chambers provide heat transfer by creating a vapor-liquid phase change in the working fluid sealed within them. When the vapor or liquid working fluid is being transported, changes in the shape of the vapor chamber can affect the flow rate. For instance, if the cross-sectional area of ​​the vapor chamber decreases, the flow rate of the working fluid will increase. If the vaporization of the working fluid accelerates, it can also affect the return flow of the liquid working fluid, potentially preventing it from returning and causing the so-called "dry burning" problem. Therefore, avoiding this problem is one of the important design challenges for vapor chambers today. Summary of the Invention

[0004] The main objective of this invention is to provide a heat spreader structure that, by adding a heat spreader structure, controls the flow rate of the working fluid inside the heat spreader, thereby preventing the heat transfer efficiency from being affected by the shape design requirements of the heat spreader.

[0005] To achieve the above objectives, the present invention provides a heat spreader turbulence structure, comprising a lower plate and an upper plate overlapping each other to form an internally hollow structure, and having an evaporation section and a condensation section formed by the lower plate and the upper plate, and a transmission section communicating between the evaporation section and the condensation section; wherein, the transmission section is provided with a few turbulence columns supported between the lower plate and the upper plate, and the turbulence columns include at least a plurality of first columns near one end of the evaporation section and a plurality of second columns near one end of the condensation section, and the arrangement spacing between each first column is smaller than the arrangement spacing between each second column.

[0008] Optionally, the lower plate has a lower evaporation portion corresponding to the evaporation portion and a lower condensation portion corresponding to the condensation portion, and the upper plate also has an upper evaporation portion corresponding to the evaporation portion and an upper condensation portion corresponding to the condensation portion.

[0010] Optionally, the lower plate further has a lower transmission section corresponding to the transmission section, and the upper plate has an upper transmission section corresponding to the transmission section, and the transmission section gradually narrows from the evaporation section to the condensation section.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The figures shown are an exploded perspective view, a three-dimensional assembly diagram, and a planar diagram of the internal structure of the first embodiment of the present invention. The present invention provides a heat spreader structure, wherein the heat spreader 1 includes a lower plate 10 and an upper plate 11 that overlap each other to form a hollow interior, and a capillary layer 12 is coated inside the lower plate 10. The capillary layer 12 may be a woven mesh, sintered powder, or grooves formed within the lower plate 10.

[0025] As described above, the lower plate 10 and upper plate 11 of the heat spreader 1 together form an evaporation section A and a condensation section B. Specifically, the lower plate 10 has a lower evaporation section 100 corresponding to the evaporation section A and a lower condensation section 101 corresponding to the condensation section B. The upper plate 11 also has an upper evaporation section 110 corresponding to the evaporation section A and an upper condensation section 111 corresponding to the condensation section B. The area of ​​the evaporation section A can be larger than the area of ​​the condensation section B. Between the evaporation section A and the condensation section B, the heat spreader 1 has a transmission section C. Specifically, the lower plate 10 has a lower transmission section 102 corresponding to the transmission section C, and the upper plate 11 has an upper transmission section 112 corresponding to the transmission section C. Furthermore, the transmission section C gradually narrows from the evaporation section A to the condensation section B, to accommodate the fact that the area of ​​the evaporation section A is larger than the area of ​​the condensation section B.

[0026] like Figure 3As shown, the present invention mainly incorporates a turbulence-inducing structure within the aforementioned transmission section C to prevent the vaporized working fluid from accelerating as it passes through the gradually converging transmission section C from the evaporation section A to the condensation section B, thereby affecting the return velocity and flow rate of the liquid working fluid and preventing dry burning. Specifically, the turbulence-inducing structure within the transmission section C is composed of several turbulence-inducing columns 13 supported between the lower plate 10 and the upper plate 11, and includes at least several first columns 130 near one end of the evaporation section A and several second columns 131 near one end of the condensation section. The spacing d between the first columns 130 is smaller than the spacing D between the second columns 131. Furthermore, several third columns 132 may also be provided within the transmission section C between the first columns 130 and the second columns 131. Each third column 132 can be arranged sequentially from the first columns 130 to the second columns 131 to maintain the turbulence-inducing effect within the transmission section C.

[0027] Accordingly, Figure 4 As shown, the evaporation section A of the heat spreader 1 can be used on a heat source 2, while several fins 3 can be installed on the condensation section B for heat dissipation. When the evaporation section A is heated by the heat source 2, the working fluid inside the heat spreader 1 vaporizes and flows towards the condensation section B. At this time, since the spacing d between the first columns 130 is the smallest, it can provide a turbulence effect and prevent the vaporized working fluid from accelerating. Next, as... Figure 5 As shown, the vaporized working fluid passing through the transmission section C is continuously affected by the turbulence structure, gradually slowing down its flow rate. When it finally passes through the second column 131, the spacing D between the second columns 131 is at its maximum, allowing the vaporized working fluid to smoothly enter the condenser section B for cooling. Simultaneously, the working fluid, which returns to a liquid state in the condenser section B, flows back through the capillary layer 12 located in the lower plate 10. Furthermore, the vaporized working fluid in the transmission section C is no longer accelerated due to the turbulence structure, allowing it to smoothly pass through the capillary layer 12 while maintaining its proper capillary force and quickly flowing back to the evaporator section A, thus preventing dry burning.

[0028] Please see again Figure 1 and Figure 2 As shown, the present invention provides a plurality of support columns 14 in the upper evaporation section 110 and upper condensation section 111 of the evaporation section A and the condensation section B. Although the support columns 14 are also used to support the area between the lower plate 10 and the upper plate 11, they are not limited in terms of spacing as mentioned above because the turbulence problem is not considered. The number of support columns 14 can be configured according to the actual area size of the evaporation section A and the condensation section B. Generally speaking, the density of the support columns 14 is more sparse or wider than the density of the turbulence columns 13 mentioned above.

[0029] Therefore, the heat spreader structure of the present invention can be obtained by means of the above-described structure.

[0030] In addition, if Figure 6 As shown, in the second embodiment of the present invention, the heat spreader 1 can correspond to different heat sources 2 or several heat sources 2 through evaporation sections A of different shapes. At the same time, condensation sections B can be added depending on the available condensation positions. Each condensation section B and evaporation section A has a transmission section C. The shape of the transmission section C can be configured according to the actual heat source 2 and heat dissipation position. However, the design of the turbulence structure of the present invention can be used in the transmission section C to reduce or avoid the acceleration phenomenon of vaporized working fluid during transmission, which would affect the return flow effect and avoid dry burning. Thus, the heat spreader 1 can still change its shape design according to the actual environmental requirements to meet the needs of diverse environmental changes.

[0031] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
