Description

Multi-hair uniform temperature plate structure

The present invention relates to a heat exchange element, in particular to a multi-hairy temperature-averaging plate structure.

According to the existing Vapor Chamber, it is mainly composed of two upper and lower plates with good thermal conductivity that are sealed and welded together to form a vacuum chamber. The interior of the chamber contains high-efficiency heat transfer materials such as capillary structures and working fluids. As a result, after the Vapor Chamber contacts the heat source, it can quickly transfer and diffuse the heat to its large area of the plate surface for cooling. It has become one of the indispensable heat dissipation components today.

In actual applications, the temperature vapor chamber often needs to change its geometry depending on the application scenario, or even design its surface into multiple sections that are not on the same horizontal plane, so as to match the peripheral components of the application scenario and effectively utilize the surface area of the board.

However, since the working fluid must reflux inside the temperature-vaporizing plate to maintain its heat exchange cycle, if the shape of the temperature-vaporizing plate is changed, especially if it is designed to have a step difference, the inside of the plate will be thinner to match the shape change, which is very likely to affect the reflux efficiency of the working fluid.

In view of this, the inventors of the present invention have conducted intensive research and applied theories to improve and solve the above-mentioned deficiencies, and finally proposed the present invention which has a reasonable design and effectively improves the above-mentioned deficiencies.

The main purpose of the present invention is to provide a multi-capillary temperature plate structure, which adopts a multi-capillary matching method, especially using bundled capillaries as the main flow of working fluid in transmission to maintain the reflux efficiency of the working fluid in the temperature plate.

In order to achieve the above-mentioned purpose, the present invention provides a multi-capillary temperature plate structure, including a shell, a composite capillary and a plurality of supporting structures: the shell includes a first plate and a second plate covered together, and has a first area, a second area, and a connecting area connecting the first area and the second area, and the connecting area forms at least a step; the composite capillary is arranged in the shell, and includes a first capillary arranged in the first plate and a second capillary arranged in the first plate. The second capillary, the third capillary arranged in the second plate, and the bundled capillary extending between the first area and the second area through the connecting area; each supporting structure is supported in the housing; wherein the bundled capillary extends from the first area to the second area through the spacing of the supporting structure and is sandwiched between the first plate and the second plate, and an overlapping area formed by the first capillary and the second capillary overlaps is formed on the connecting area, and the overlapping area is located downstream of the step difference part, so as to maintain the reflux effect of the working fluid in the temperature-averaging plate.

In order to enable the Honorable Review Committee to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the attached drawings are only provided for reference and explanation and are not used to limit the present invention.

Please refer to FIG1, which is a three-dimensional exploded schematic diagram of the present invention. The present invention provides a multi-capillary temperature plate structure, including a shell 1, a composite capillary 2 disposed in the shell 1, and a plurality of supporting structures 3; wherein:

The housing 1 comprises a first plate 10 and a second plate 11, and has a first area 100/110, a second area 101/111, and a connecting area 102/112 connecting the first area 100/110 and the second area 101/111. As shown in FIG4, the connecting area 102/112 has at least one step 103/113 formed thereon, so that the first area 100/110 and the second area 101/111 have a height difference, that is, the first area 100/110 and the second area 101/111 are not at the same level. The step portion 103 / 113 may be gradually widened from the connecting area 102 / 112 toward the second area 101 / 111 in the width direction (as shown in FIGS. 1 to 3 ).

Referring to FIG. 1 , the composite capillary 2 is disposed on the inner wall of the housing 1 and includes a first capillary 20 and a second capillary 21 attached to the first plate 10 of the housing 1, a third capillary 23 attached to the second plate 11 of the housing 1, and a bundle of capillaries 24 extending between the first area 100/110 and the second area 101/111 through the connecting area 102/112 of the housing 1. As shown in FIG. 2 , the capillaries in the first plate 10 are composed of the first capillaries 20 arranged in the first area 100 and the second capillaries 21 arranged in the second area 101, and the first capillaries 20 and the second capillaries 21 extend toward the connecting area 102 respectively to form an overlapping area O formed by the overlapping of the first capillaries 20 and the second capillaries 21 on the connecting area 102. The first capillaries 20 are powder sintering, the second capillaries 21 are woven mesh, and the overlapping area O is a mixture of powder winding and woven mesh.

As mentioned above, as shown in FIG. 3 , the third capillaries 23 are arranged in the second plate 11 , that is, the first area 110 , the second area 111 and the connecting area 112 in the second plate 11 are all formed by the third capillaries 23 , and the third capillaries 23 are a woven mesh.

Please refer to FIG. 1 and FIG. 3 together. The supporting structures 3 are supported between the first plate 10 and the second plate 11 of the shell 1, and include a first supporting column 30 distributed in the first area 100/110 of the shell 1, a second supporting column 31 distributed in the connecting area 102/112 of the shell 1, and a third supporting column 32 distributed in the second area 101/111 of the shell 1, wherein each first supporting column 30 includes a solid portion 300 and a sintered portion 301 wrapped around the solid portion 300, each second supporting column 31 is formed of a solid column made of a material such as copper or aluminum, and each third supporting column 32 is formed by sintering powder. Finally, the long-strip bundled capillaries 24 pass through the spacing of the supporting structures 3 and extend from the first area 100/110 of the housing 1 through the connecting area 102/112 to the second area 101/111, so as to be sandwiched between the first plate 10 and the second plate 11. The bundled capillaries 24 are fiber bundles.

Accordingly, please refer to FIG. 1 and FIG. 4 together. The above-mentioned bundled hair 24 has a first section 240 and a second section 241 far away from the first section 240, wherein the first section 240 can be in a straight line and extend from the first area 100/110 of the shell 1 to the connecting area 102/112 to connect to the second section 241 located in the second area 101/111, and the extension direction of the second section 241 can be adjusted according to the shape of the shell 1; for example, a curved section 242 is formed between the first section 240 and the second section 241, so that the second section 241 extends toward the curved direction of the curved section 242. In addition, since the connecting area 102/112 of the housing 1 has the step portion 103/113, the bundled capillaries 24 also have an inclined section 243 passing through the step portion 103/113. As shown in FIG5, the overlapping area O on the connecting area 102/112 is located downstream of the step portion 103/113 or the inclined section 243.

In addition, the second area 101/111 of the above-mentioned shell can be further connected to an extended area 104/114, and the extended area 104/114 can be determined according to the actual shape required by the temperature balance plate, and the second section 241 of the bundled capillaries 24 can also extend toward the extended area 104/114; wherein, the extended area 104 is also extended and attached to the first plate 10 by the second capillaries 21, and the extended area 114 is also extended and attached to the second plate 11 by the third capillaries 23, and the supporting structure 3 therein is a plurality of third supporting columns 32.

Therefore, by the above-mentioned structural composition, the multi-hairy temperature-equalizing plate structure of the present invention can be obtained.

Therefore, by means of the multi-capillary temperature-averaging plate structure of the present invention, the first area 100/110 and the second area 101/111 of the housing 1 can be respectively attached to heat sources of different thicknesses or heights through the step portion 103/113 of the housing 1, and at the same time, the working fluid reflux efficiency between the first area 100/110 and the second area 101/111 can be maintained through the capillaries 24; more importantly, the connecting area 102/112 forms an overlapping area O where the first capillaries 20 and the second capillaries 21 overlap at the downstream of the step portion 103/113 (or the inclined section 243 of the capillaries 24), which can help cooperate with the capillaries 24 to quickly reflux the working fluid to the first area 100/110.

In addition, the present invention configures the first supporting column 30, the second supporting column 31 and the third supporting column 32 on the supporting structures 3 according to the first area 100/110, the connecting area 102/112 and the second area 101/111 respectively; wherein the first supporting column 30 includes a solid portion 300 and a sintered portion 301 wrapped around the outer periphery of the solid portion 300, so it has good support and partial reflow functions, and the second supporting column 31 is located at the step portion 103/113 and provides a stable support function with a solid column, and finally the third supporting column 32 is formed by sintering powder in consideration of the reflow efficiency, so as to optimize the support for each part of the temperature balancing plate and provide a supporting structure 3 with functions such as reflow.
