Description

Technical Field

[0001] The utility model relates to the technical field of temperature balancing plates, and in particular to a support column structure and a temperature balancing plate. Background Art

[0002] With the progress and development of society, the field of mechanical processing and manufacturing has also developed rapidly. Now many technological products (electronic products / home appliances) are used in people's lives, and people's dependence on them is getting stronger and stronger, which leads to an increasing demand for these products, especially electronic devices. Now people have higher requirements for their portability and lightweight, requiring the body to be small, thin and light. Based on the characteristics of these electronic devices, they often generate heat when they are running. For these thin and light bodies, a little heat generation can be easily perceived by users, resulting in a poor user experience. Therefore, these devices need a temperature control system to improve the stability of the equipment and thus increase the user experience.

[0003] VC heat spreader is a common heat dissipation method used in electronic equipment. It is small in size and has high heat dissipation efficiency. It uses the principle of gas-liquid phase change to quickly transfer heat to the entire product, reducing local temperature to achieve heat dissipation effect. Most of the support columns on existing heat spreaders are etched or stamped, and are processed on the original material. The former pollutes the environment and has a low reusability rate. The latter requires the replacement of stamping dies for each product, which will increase costs and reduce precision. Since the capillary core is woven from strips of metal wire of about 0.05mm, when the metal support column is over-pressurized, the capillary core will break. Therefore, we have made improvements to this and proposed a support column structure and heat spreader. Summary of the invention

[0004] The purpose of the utility model is to solve the problems that most of the existing support columns on the existing temperature equalizing plates are formed by etching or stamping, which has the problems of great environmental pollution and low precision.

[0005] In order to achieve the above-mentioned purpose of the invention, the utility model provides a support column structure and a temperature equalizing plate to improve the above-mentioned problem.

[0006] The specific application is as follows:

[0007] A support column structure comprises a bottom plate, a plurality of carbon fiber support columns are arranged on the top of the bottom plate, and the carbon fiber support columns are made of carbon fiber.

[0008] As a preferred technical solution of the present application, the shape of the carbon fiber support column is truncated cone or cylindrical.

[0009] As a preferred technical solution of the present application, the carbon fiber support column and the base plate are connected by welding or gluing.

[0010] A temperature equalizing plate uses a support column structure, including a cover plate connected to a base plate, wherein the middle portion of the cover plate is recessed toward a side away from the base plate to form an accommodating cavity, and an end of the carbon fiber support column away from the base plate contacts the accommodating cavity.

[0011] As a preferred technical solution of the present application, a plurality of mounting holes are provided on the base plate and the cover plate, and the mounting holes on the base plate correspond to the mounting holes on the cover plate.

[0012] As a preferred technical solution of the present application, a small degassing tube is fixedly connected to one side of the cover plate, and one end of the small degassing tube extends into the accommodating cavity.

[0013] As a preferred technical solution of the present application, a sealing ring is fixedly connected to the outer side of the bottom plate, and the inner wall of the sealing ring is in contact with the outer side surface of the cover plate.

[0014] As a preferred technical solution of the present application, a plurality of fixing members are provided between the cover plate and the sealing ring, and the fixing members are used for fixing the cover plate and the sealing ring.

[0015] As a preferred technical solution of the present application, the fixing member includes a slot opened on the top of the cover plate and a spring sheet rotatably arranged on the top of the sealing ring, the bottom of the spring sheet is fixedly connected with a convex strip, and the outer surface of the convex strip is plugged into the slot.

[0016] As a preferred technical solution of the present application, the fixing member further comprises a connecting shaft, the connecting shaft is fixedly mounted on the top of the sealing ring, and the spring sheet is sleeved on the outer surface of the connecting shaft via a damping bearing.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the scheme of this application:

[0019] In order to solve the problem that most of the support columns on the existing temperature equalizing plates in the prior art are formed by etching or stamping, which has the problems of great environmental pollution and low cutting precision, the present application sets up carbon fiber support columns and adopts carbon fiber support columns instead of etching and stamping support columns. Carbon fiber has the advantages of good heat dissipation effect, long service life and light weight. Since the carbon fiber support columns are set on the bottom plate in a non-stamping or etching manner, the capillary core will not break when the carbon fiber support columns are over-pressurized, and the pollution to the environment can be reduced. The utilization rate is high and the precision can be improved. When the temperature equalizing plate undergoes gas-liquid conversion, the carbon fiber can condense the gas into liquid more quickly, and since the capillary core structure is not broken when over-pressurized, the liquid reflux speed is increased, thereby improving the overall performance of the product.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0032] As described in the background technology, VC temperature equalizer is a common heat dissipation method used in electronic equipment. It has a small size and high heat dissipation efficiency. It uses the gas-liquid phase change principle to quickly transfer heat to the entire product, reducing the local temperature to achieve the heat dissipation effect. Most of the support columns on the existing temperature equalizer are formed by etching or stamping, and are processed on the original material. The former pollutes the environment and has a low recycling rate. The latter requires the replacement of the stamping mold for each product, which will lead to increased costs and low precision. Since the capillary core is woven from strips of metal wire of about 0.05mm, when the metal support column is over-pressurized, problems such as capillary core breakage will occur.

[0033] In order to solve this technical problem, the utility model provides a support column structure and a temperature equalizing plate.

[0034] Specifically, please refer to Figure 1 , the support column structure specifically includes:

[0035] The bottom plate 1 has a plurality of carbon fiber support columns 2 arranged on the top of the bottom plate 1. The carbon fiber support columns 2 are made of carbon fiber.

[0036] The present application sets a carbon fiber support column 2, and adopts the carbon fiber support column 2 instead of the etching and stamping support column. The carbon fiber has the advantages of good heat dissipation effect, long service life, light weight, etc. Since the carbon fiber support column 2 is set on the base plate 1 in a non-stamping or etching manner, when the carbon fiber support column 2 is over-pressurized, there will be no problems such as capillary wick breakage, and the pollution to the environment can be reduced. The utilization rate is high and the accuracy can be improved. When the gas-liquid conversion is carried out on the temperature equalizing plate, the carbon fiber can condense the gas into liquid more quickly, and when over-pressurized, the capillary wick structure is not broken, which increases the liquid reflux speed and improves the overall performance of the product.

[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Example 1, please refer to Figure 1A support column structure includes a base plate 1, and a plurality of carbon fiber support columns 2 are arranged on the top of the base plate 1. The carbon fiber support columns 2 are made of carbon fiber. The present application arranges the carbon fiber support columns 2, and adopts the carbon fiber support columns 2 to replace the etching and stamping support columns. The carbon fiber has the advantages of good heat dissipation effect, long service life, light weight, etc. Since the carbon fiber support columns 2 are arranged on the base plate 1 in a non-stamping or etching manner, the capillary core will not break when the carbon fiber support columns 2 are over-pressurized, and the pollution to the environment can be reduced, the utilization rate is high, and the accuracy can be improved. When the temperature plate is converted from gas to liquid, the carbon fiber can condense the gas into liquid more quickly, and the capillary core structure is not broken when over-pressurized, which increases the speed of liquid reflux and improves the overall performance of the product.

[0041] Carbon fiber has good machinability and plasticity, and can be customized according to actual needs. In order to improve the appearance quality and anti-corrosion performance of this application, the surface of this application will be treated with anti-oxidation, and a protective film will be formed on the surface of this application by vacuum evaporation, and then sintering will be performed to improve the anti-oxidation and anti-corrosion properties of this application. Vacuum evaporation refers to a process in which an evaporation coating material is placed under vacuum conditions and vaporized, so that the particles fly to the surface of the sheet and condense into a film. This technology has the advantages of simple film forming method, high film purity and high density. This process can effectively extend the service life of this application, reduce performance degradation or scrapping due to poor appearance, and improve appearance yield. The carbon fiber support column 2 is formed by laser cutting of carbon fiber sheets, and then the carbon fiber support columns 2 are connected together.

The truncated cone-shaped setting makes the column gap between the carbon fiber support columns 2 large, and more space passes through per unit time; the carbon fiber support column 2 is cylindrical, and the cylindrical carbon fiber support column 2 is easy to process.

[0044] Embodiment 3 further optimizes the support column structure provided in Embodiment 1. Specifically, the carbon fiber support column 2 and the base plate 1 are connected by welding or gluing, and the welding is performed by laser welding.

[0045] Example 4, please refer to Figure 2-Figure 5A temperature equalizing plate uses a support column structure, including a cover plate 3 connected to a base plate 1, the middle portion of the cover plate 3 is recessed toward a side away from the base plate 1 to form a receiving cavity 301, and one end of a carbon fiber support column 2 away from the base plate 1 is in contact with the receiving cavity 301, and the receiving cavity 301 provides the required space for the arrangement of the carbon fiber support column 2.

[0046] After the base plate 1 and the cover plate 3 are manufactured, the base plate 1 is connected to the carbon fiber support column 2, and then an anti-oxidation treatment step is added. After the vacuum evaporation treatment, the base plate 1 and the cover plate 3 are sintered, which can not only strengthen the connection between the base plate 1 and the cover plate 3, but also strengthen the connection between the base plate 1 and the carbon fiber support column 2, thereby enhancing product reliability.

[0047] A plurality of mounting holes 4 are formed on the bottom plate 1 and the cover plate 3 , and the mounting holes 4 on the bottom plate 1 correspond to the mounting holes 4 on the cover plate 3 .

[0048] A degassing tube 302 is fixedly connected to one side of the cover plate 3 , and one end of the degassing tube 302 extends into the accommodating cavity 301 .

[0049] Embodiment 5 further optimizes the temperature equalizing plate provided in Embodiment 4. Specifically, the base plate 1 and the cover plate 3 are connected together by welding or bonding. Welding or bonding can improve the connection strength between the base plate 1 and the cover plate 3 and the sealing of the connection.

[0050] Example 6, further optimizes the temperature homogenizing plate provided in Example 4, specifically, as follows Figure 6-Figure 7 As shown, a sealing ring 5 is fixedly connected to the outer side of the bottom plate 1 , and the inner wall of the sealing ring 5 contacts the outer side surface of the cover plate 3 . The provision of the sealing ring 5 can improve the sealing performance of the connection between the bottom plate 1 and the cover plate 3 .

[0051] Further, such as Figure 6-Figure 9 As shown, a plurality of fixing parts are provided between the cover plate 3 and the sealing ring 5, and the fixing parts are used to fix the cover plate 3 and the sealing ring 5. The cover plate 3 and the base plate 1 are detachably connected and fixed by the provided fixing parts. After the fixing parts release the fixing between the cover plate 3 and the base plate 1, the cover plate 3 can be removed for easy cleaning and maintenance.

[0052] Further, such as Figure 6-Figure 9As shown, the fixing part includes a slot 603 opened on the top of the cover plate 3 and a spring piece 601 rotatably arranged on the top of the sealing ring 5. The bottom of the spring piece 601 is fixedly connected with a convex strip 602, and the outer surface of the convex strip 602 is plugged into the slot 603. The top of the spring piece 601 is flush with the top of the cover plate 3. When the heat dissipation structure is installed on the top of the cover plate 3, the spring piece 601 can cooperate with the cover plate 3 to provide support for the heat dissipation structure. The spring piece 601 is made of spring steel. Pulling the spring piece 601 can separate the convex strip 602 from the slot 603. At this time, the spring piece 601 can rotate to release the fixation of the cover plate 3.

[0053] Further, such as Figure 6 As shown, the fixing member also includes a connecting shaft 6, which is fixedly mounted on the top of the sealing ring 5, and the spring piece 601 is sleeved on the outer surface of the connecting shaft 6 through a damping bearing, and the spring piece 601 can be connected to the sealing ring 5 through the connecting shaft 6.

[0054] When disassembling, pull the spring piece 601 upwards to separate the convex strip 602 from the card slot 603, then rotate the spring piece 601 180 degrees around the connecting shaft 6 to separate the spring piece 601 from the cover plate 3, and pull the cover plate 3 to remove the cover plate 3. When installing, put the cover plate 3 back into the sealing ring 5, and then rotate the spring piece 601. When the convex strip 602 is aligned with the card slot 603, the convex strip 602 and the card slot 603 are plugged together, and the spring piece 601 presses and fixes the cover plate 3.
