Description

Technical Field

[0001] The utility model relates to the technical field of temperature averaging plates, in particular to an improved temperature averaging plate. Background Art

[0002] A vapor chamber is a device used to maintain or regulate temperature by evenly distributing heat across its surface or interior. Vapor chambers are typically made of materials with good thermal conductivity, such as aluminum, copper, or specialized composites. They can be passive, relying solely on the thermal conductivity of the material to achieve temperature uniformity, or active, equipped with heating elements or cooling systems that use electronic controls to precisely regulate temperature.

[0003] The temperature transfer of the temperature equalizer refers to the process of transferring heat from the high temperature area to the low temperature area. Heat is transferred in space by the macroscopic movement of the convective fluid (liquid or gas). In some special environments, such as the environment of the temperature transfer process with high precision requirements, the temperature equalizer is needed to control its heat conduction speed so that the temperature sensing element can adapt to the temperature change. Since the existing temperature equalizer generally adopts an integrated molding structure and does not have the effect of delaying the temperature change, its structure needs to be further processed and improved during use, which increases the process and reduces the work efficiency. For this reason, the inventors have proposed an improved temperature equalizer to solve the above-mentioned technical problems. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0005] An improved temperature equalizing plate comprises a plate body, a gland and a partition. The plate body, the gland and the partition are all detachable structures. The gland is installed at one end of the plate body. An inner tank for storing coolant is provided inside the plate body. A chute for placing the partition is provided on the inner wall of the inner tank. The chute is in an inwardly concave arc shape. A plurality of through holes for assisting the gasification and circulation of coolant are provided on the surface of the partition. The through holes penetrate the surface of the partition. The interior of the gland is hollow. A sealing ring is connected to the inner wall of the gland to prevent leakage of the inner tank.

[0006] This structure consists of three parts: a plate body, a pressure cover and a partition. The three parts are designed to be detachable, making maintenance or replacement more convenient. The pressure cover is firmly installed at one end of the plate body, and an inner groove is designed inside the plate body to hold the coolant. There are multiple through holes distributed on the surface of the partition. The through holes not only penetrate the entire thickness of the partition, but also play a key auxiliary role, that is, delaying the rapid vaporization and smooth circulation of the coolant. In some specific environments, a gradually progressive heat dissipation effect is required, and the partition plays the role of delaying the rapid vaporization and smooth circulation of the coolant, so that the heat dissipation effect is gradually progressive. When the partition is removed, the heat dissipation effect is restored to be the same as that achieved by the temperature equalization plate in the prior art; in addition, the interior of the pressure cover is designed to be hollow, and a sealing ring is installed on its inner wall to ensure that the inner groove will not leak during operation, thereby improving the overall safety and reliability.

[0007] Furthermore, a card slot is provided on the surface of the plate body, and the card slot is concave in shape. A card block is connected to the surface of the pressure cover and is installed in pair with the card slot, and the card block is convex in shape. The card slot and the card block are connected by a snap-fit ​​connection. This connection method can achieve quick assembly and disassembly, and is convenient for the installation and maintenance of the plate body and the pressure cover. The snap-fit ​​connection does not require additional fasteners such as screws or bolts, thereby simplifying the assembly process and reducing costs. In addition, since the card slot is concave in shape and the card block is convex in shape, this design can provide a good mechanical locking effect, increase the stability of the connection, and reduce the risk of loosening due to vibration or impact. The snap-fit ​​connection also has a certain elasticity and can adapt to plates and pressure covers of different thicknesses or sizes, providing a certain fault tolerance space, so that the product has better versatility and adaptability.

[0008] Furthermore, the thickness of the partition is 1.5 mm, the partition is made of copper, and the plate body and the pressure cover are both made of aluminum; the partition is made of copper, has good thermal conductivity, can effectively conduct heat, reduce heat accumulation at the partition, and thus improve the heat dissipation efficiency of the overall equipment; at the same time, copper has high mechanical strength and can withstand certain pressure and impact, ensuring the structural stability and durability of the partition; the plate body and the pressure cover are made of aluminum, which has the characteristics of light weight and can reduce the weight of the entire temperature equalizing plate, making it easy to carry and install; aluminum also has good thermal conductivity, which helps to improve the heat dissipation effect of the temperature equalizing plate. In addition, aluminum also has good corrosion resistance, which can extend the service life of the temperature equalizing plate.

[0009] Furthermore, both ends of the partition are provided with stepped grooves that are installed in pair with the slide groove. The stepped grooves can slide along the surface of the slide groove, and the interval between the stepped grooves and the partition is 0.5mm. The use of a small gap can ensure that the partition slides smoothly in the slide groove, while reducing the noise and wear caused by friction. In addition, the appropriate gap helps the partition to maintain good operating performance when the temperature changes and causes the material to expand or contract, avoids jamming or over-tightening, thereby extending the performance and service life of the product. The use of stepped grooves further reduces the noise and wear caused by the overall friction of the partition, making it easier for users to remove or install the partition, and achieves a quick installation effect.

[0010] Furthermore, the bottom of the partition is connected to a number of support columns for supporting the partition, one end of the support column is in contact with one end of the inner groove, and the lengths of the support columns vary. Since the partition and the slide groove are in a concave arc shape after installation, the lengths of the support columns are set so that when the partition and the slide groove are in a concave arc shape after installation, one end of the support column can still be in contact with one end of the inner groove, so that the support column plays a load-bearing role and prevents the partition from being affected by gravity and leaving the surface of the slide groove.

[0011] Furthermore, the surface of the plate is provided with a plurality of anti-slip grooves for increasing friction, and the anti-slip grooves are linearly arranged on the surface of the plate, and the spacing between two adjacent anti-slip grooves is equal; when the user's hand contacts the outer side of the plate, the anti-slip grooves increase the contact points between the user's hand and the outer side of the plate, and increase the contact area, thereby achieving the effect of increasing friction and playing an anti-slip role, which is convenient for users to reduce slipping during the installation process. The linear arrangement and equal spacing are adopted to make the friction between the anti-slip grooves consistent, which facilitates the mutual transmission of force.

[0012] Compared with the prior art, the present invention has the following advantages: the plate body, the gland and the partition are composed of three parts, and the three parts are designed to be detachable, making maintenance or replacement more convenient. The gland is firmly mounted on one end of the plate body, and an inner groove is designed inside the plate body to accommodate the coolant. The surface of the partition is distributed with multiple through holes, which not only penetrate the entire thickness of the partition but also play a role in assisting gas circulation.

[0013] In addition, the baffle delays the rapid vaporization and smooth circulation of the coolant. In some specific environments, a gradually progressive heat dissipation effect is required, and the baffle plays the role of delaying the rapid vaporization and smooth circulation of the coolant, making the heat dissipation effect gradually progressive, making the temperature gradually rise or fall, and avoiding the impact of dimensional accuracy due to excessive temperature changes;

[0014] When the partition is removed, the heat spreader restores the same heat dissipation effect as that achieved by the heat spreader in the existing technology; in addition, the interior of the pressure cover is designed to be hollow, and a sealing ring is installed on its inner wall to ensure that the inner tank will not leak during operation, thereby improving overall safety and reliability.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0022] For this example, please refer to Figure 1-Figure 5 , a specific implementation of an improved temperature equalizing plate includes a plate body 1, a gland 2 and a partition 3. The plate body 1, the gland 2 and the partition 3 are all detachable structures. The gland 2 is installed at one end of the plate body 1. The plate body 1 is provided with an inner tank 4 for storing coolant. The inner wall of the inner tank 4 is provided with a chute 5 for placing the partition 3. The chute 5 is in an inward concave arc shape. The surface of the partition 3 is provided with a plurality of through holes 6 for assisting the gasification and circulation of the coolant. The through holes 6 pass through the surface of the partition 3. The interior of the gland 2 is hollow. The inner wall of the gland 2 is connected with a sealing ring 7 to prevent leakage of the inner tank 4.

[0023] The present structure is composed of three parts: a plate body 1, a pressure cover 2 and a partition 3. The three parts are designed to be detachable, making maintenance or replacement more convenient. The pressure cover 2 is firmly mounted on one end of the plate body 1, and an inner groove 4 is designed inside the plate body 1 to accommodate the coolant. A plurality of through holes 6 are distributed on the surface of the partition 3. The through holes 6 not only penetrate the entire thickness of the partition 3, but also play a key auxiliary role, that is, delaying the rapid vaporization and smooth circulation of the coolant. In some specific environments, a gradually progressive heat dissipation effect is required, and the partition 3 plays the role of delaying the rapid vaporization and smooth circulation of the coolant, so that the heat dissipation effect is gradually progressive. When the partition 3 is removed, the heat dissipation effect is restored to be the same as that of the temperature equalizing plate in the prior art; in addition, the interior of the pressure cover 2 is designed to be hollow, and a sealing ring 7 is installed on its inner wall to ensure that the inner groove 4 will not leak during operation, thereby improving the overall safety and reliability.

[0024] The surface of the plate body 1 is provided with a card slot 8, which is concave in shape. The surface of the pressure cover 2 is connected with a card block 9 which is installed in pair with the card slot 8, which is convex in shape. The card slot 8 and the card block 9 are snap-connected. This connection method can achieve quick assembly and disassembly, which is convenient for the installation and maintenance of the plate body 1 and the pressure cover 2. The snap-connection does not require additional fasteners such as screws or bolts, thereby simplifying the assembly process and reducing costs. In addition, since the card slot 8 is concave in shape and the card block 9 is convex in shape, this design can provide a good mechanical locking effect, increase the stability of the connection, and reduce the risk of loosening due to vibration or impact. The snap-connection also has a certain elasticity, which can adapt to plates 1 and pressure covers 2 of different thicknesses or sizes, provide a certain fault tolerance space, and make the product have better versatility and adaptability.

[0025] The thickness of the partition 3 is 1.5 mm. The partition 3 is made of copper, and the plate body 1 and the pressure cover 2 are both made of aluminum. The partition 3 is made of copper, which has good thermal conductivity and can effectively conduct heat, reducing the accumulation of heat at the partition 3, thereby improving the heat dissipation efficiency of the entire equipment. At the same time, copper has high mechanical strength and can withstand certain pressure and impact, ensuring the structural stability and durability of the partition 3. The plate body 1 and the pressure cover 2 are made of aluminum, which has the characteristics of light weight and can reduce the weight of the entire temperature equalizing plate, making it easy to carry and install. The thermal conductivity of aluminum is also good, which helps to improve the heat dissipation effect of the temperature equalizing plate. In addition, aluminum also has good corrosion resistance and can extend the service life of the temperature equalizing plate.

[0026] Both ends of the partition 3 are provided with a stepped groove 10 that is installed in pair with the slide 5. The stepped groove 10 can slide along the surface of the slide 5, and the stepped groove 10 and the partition 3 are spaced 0.5mm apart. The use of a small gap can ensure that the partition 3 slides smoothly in the slide 5, while reducing the noise and wear caused by friction. In addition, the appropriate gap helps the partition 3 to maintain good operating performance when the temperature changes and the material expands or contracts, avoids jamming or over-tightening, thereby extending the product's performance and service life. The use of the stepped groove 10 further reduces the noise and wear caused by the overall friction of the partition 3, making it easier for users to remove or install the partition 3, and achieving a quick installation effect.

[0027] The bottom of the partition 3 is connected to several support columns 11 for supporting the partition 3. One end of the support column 11 is in contact with one end of the inner groove 4. The lengths of the support columns 11 are different. Since the partition 3 and the slide groove 5 are installed in a concave arc shape, the lengths and heights of the support columns 11 are set to be in a concave arc shape when the partition 3 and the slide groove 5 are installed. One end of the support column 11 can still be in contact with one end of the inner groove 4, so that the support column 11 plays a load-bearing role and prevents the partition 3 from being separated from the surface of the slide groove 5 under the influence of gravity. When the partition 3 is connected to the slide groove 5, due to the influence of the concave arc shape of the slide groove 5, the partition 3 presents the same shape after installation. This shape is conducive to the collection of the coolant after returning from gasification to liquefaction. The concave design makes it easier for the liquefied coolant to flow back from the through hole 6 to the inside of the inner groove 4, which is convenient for the circulation of the coolant.

[0028] The surface of the plate body 1 is provided with a plurality of anti-slip grooves 12 for increasing friction. The anti-slip grooves 12 are linearly arranged on the surface of the plate body 1, and the spacing between two adjacent anti-slip grooves 12 is equal. When the user's hand contacts the outer side of the plate body 1, the anti-slip grooves 12 increase the contact points between the user's hand and the outer side of the plate body 1, and increase the contact area, thereby achieving the effect of increasing friction and playing an anti-slip role, which is convenient for users to reduce slipping during the installation process. The linear arrangement and equal spacing make the friction between the anti-slip grooves 12 consistent, which facilitates the mutual transmission of force.

[0029] The key points of the design of the present invention are: it is composed of a plate body 1, a gland 2 and a partition 3, and the three parts are designed to be detachable, making maintenance or replacement more convenient. The gland 2 is firmly mounted on one end of the plate body 1, and an inner groove 4 is designed inside the plate body 1 for accommodating coolant. A plurality of through holes 6 are distributed on the surface of the partition 3. The through holes 6 not only penetrate the entire thickness of the partition 3, but also play a role in assisting gas circulation.

[0030] In addition, the partition 3 delays the rapid vaporization and smooth circulation of the coolant. In some specific environments, a gradually progressive heat dissipation effect is required, and the partition 3 plays the role of delaying the rapid vaporization and smooth circulation of the coolant, so that the heat dissipation effect is gradually progressive, and the temperature is gradually increased or decreased, avoiding the impact of dimensional accuracy due to excessive temperature changes.

[0031] When the partition 3 is removed, the heat spreader restores the same heat dissipation effect as that achieved by the heat spreader in the prior art; in addition, the interior of the pressure cover 2 is designed to be hollow, and a sealing ring 7 is installed on its inner wall to ensure that the inner tank 4 does not leak during operation, thereby improving the overall safety and reliability.

[0032] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
