Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of temperature averaging plates, in particular to a temperature averaging plate radiator. 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] A vapor chamber heat sink utilizes the temperature-distributing properties of a vapor chamber to quickly disperse heat. This type of heat sink is typically made of metal and offers excellent thermal conductivity. The vapor chamber contains a working fluid. When the device generates heat, the vapor chamber absorbs it and quickly distributes it evenly across the entire heatsink surface, effectively reducing the device's temperature. Vapor chamber heat sinks are widely used in electronic equipment, computer hardware, LED lighting, and new energy vehicles.
[0004] The existing Chinese patent with reference publication number CN218499483U discloses a heat spreader, including an evaporation zone and a condensation zone, wherein the evaporation zone is constructed with a first flow channel; the condensation zone is constructed with a second flow channel, the second flow channel is connected to the first flow channel, and forms a circulation loop; wherein the first flow channel and / or the second flow channel include a plurality of curved segments and straight segments connected in sequence, and a heat transfer medium is poured into the heat spreader, and the heat transfer medium flows unidirectionally in the circulation loop under the action of the pressure difference to achieve heat transfer. In this way, the heat transfer medium in the heat spreader is driven by heat and pressure difference as a driving force during the circulation of the circulation loop, and the circulation flow is achieved without consuming external mechanical work and electrical work; thereby avoiding local overheating and improving the heat dissipation effect of the radio frequency module. The present application also discloses a radiator, which also includes: a fin group, and the fin includes: a first bending portion.
[0005] Although this patent has the effect of heat dissipation, it does not have the function of supporting the fins. When the fin surface is squeezed by external force, the fins may bend due to the lack of support function, resulting in the phenomenon of hindered heat dissipation. On the other hand, when the fins are bent and need to be replaced to another installation environment, the fins need to be corrected due to the bending of the fins to facilitate the accuracy of installation, which increases the process and reduces work efficiency. For this reason, the inventors proposed a temperature dispersion plate radiator to solve the above-mentioned technical problem of supporting the fins or heat sinks and reducing the probability of bending. Utility Model Content
[0006] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.
[0007] The heat dissipation device is a heat dissipation device, a heat dissipation device, a heat dissipation device for dissipating heat, and a heat dissipation device for dissipating heat. The heat dissipation device is a heat dissipation device for dissipating heat. The heat dissipation device is a heat dissipation device for dissipating heat. The heat dissipation device is a heat dissipation device for dissipating heat.
[0008] The design of the heat dissipation holes and the mounting groove through-holes can effectively improve heat dissipation efficiency. With this through-hole design, the heat dissipation holes can not only directly dissipate the heat inside the heat sink, but also increase the heat dissipation area with the help of the tooth-shaped structure of the mounting groove, thereby improving heat dissipation performance. In addition, the through-hole heat dissipation holes help form air flow channels, promoting the exhaust of hot air and the intake of cold air, further enhancing the heat dissipation effect. This design enables the radiator to dissipate the heat generated by the vapor chamber more quickly and evenly, ensuring that the vapor chamber operates at a balanced temperature.
[0009] By adopting the arrangement of tooth-shaped hollow placement grooves inside the heat sink, the heat sink is made into a thin sheet shape, thereby increasing its cooling effect. However, since the thin sheet is prone to deformation, a bottom plate and several support plates for supporting the heat sink are added inside the placement groove. The support plates are evenly distributed on the surface of the bottom plate. The spaced support plates support the heat sink while avoiding affecting the heat dissipation effect of the heat sink.
[0010] In addition, the inner wall of the heat sink is supported by the arc-shaped top of the support plate and several top blocks on the surface of the support plate, which increases the force points while retaining the original heat dissipation area. The point contact method is used to reduce temperature transfer, ensure that the surface temperature of the heat sink is uniform, avoid the probability of deformation caused by long-term local heating, increase the support stability, and ensure uniform heat dissipation effect.
[0011] Furthermore, the interior of the bottom plate is a hollow liquid storage tank, the inner surface of the liquid storage tank is connected to a plurality of reinforcing ribs, the two ends of the reinforcing ribs respectively abut against the inner surface of the liquid storage tank, and the surface of the reinforcing ribs is provided with a plurality of flow holes for assisting the gasification and circulation of the liquid, and the flow holes penetrate the surface of the two ends of the reinforcing ribs;
[0012] The design of the flow holes running through the surfaces at both ends of the reinforcement ribs can promote the vaporization process of the cooling liquid in the liquid reservoir. The flow holes provide additional surface area for the liquid, thereby increasing the contact opportunities between the liquid and the surrounding environment, helping the liquid to absorb heat and convert into gas faster. In addition, the flow holes can also help reduce the resistance to liquid flow, making the liquid more evenly distributed in the liquid reservoir, further improving the vaporization efficiency. The reinforcement ribs provide structural support to ensure that the liquid reservoir maintains a stable shape under the action of liquid pressure, while the flow holes optimize the vaporization performance of the liquid without sacrificing structural strength.
[0013] Furthermore, the surface of the bottom plate is provided with a plurality of air holes for assisting the vaporization and circulation of the liquid. The air holes penetrate the surface of the bottom plate and are connected to the interior of the liquid storage tank, and the reinforcing ribs are located between two adjacent air holes. The reinforcing ribs can provide additional structural strength and rigidity to prevent the bottom plate from deforming under pressure or temperature changes. In addition, the reinforcing ribs help to disperse stress and reduce damage to the bottom plate caused by the pressure generated by liquid vaporization. At the same time, they can also help maintain the flatness of the bottom plate and ensure the size and position accuracy of the air holes, thereby ensuring the efficiency and uniformity of the liquid vaporization and circulation.
[0014] Furthermore, the base and the heat sink are both made of aluminum; aluminum has a high thermal conductivity and can effectively conduct heat from the heat source to the heat sink, thereby improving the heat dissipation efficiency. In addition, the density of aluminum is low, which can make the overall weight of the base and the heat sink lighter, convenient for installation and transportation, while reducing the burden on the equipment, and a dense oxide film is easily formed on the surface of the aluminum, which has a certain corrosion resistance and extends the service life of the heat dissipation system; in addition, aluminum is easy to process and shape, and heat sinks of various shapes and sizes can be designed according to the heat dissipation requirements to meet the heat dissipation requirements of different equipment, facilitate operator transportation and processing, and reduce manufacturing costs.
[0015] Furthermore, there is a 15° angle between the top block and the bottom plate, and the top block gradually converges toward the top of the support plate along the 15° angle, and the top block is triangular in shape; a triangle is used as the supporting shape of the top block, so that the top block has relative stability. This design helps to improve the stability of the overall structure, and through the inclined design at a 15° angle, the top block can better adapt to the shape of the heat sink during the retraction process, thereby optimizing space utilization. At the same time, the force exerted by the heat sink on the support plate from top to bottom can be adapted to the force exerted by the heat sink on the support plate by forming a 15° angle, thereby supporting the heat sink and reducing the probability of deformation of the heat sink; in addition, the inclined design shape at a 15° angle makes it easier to assemble the support plate, is easy to cooperate with the support plate, improves assembly efficiency, and facilitates installation.
[0016] Furthermore, a non-slip pad is provided on the top of the heat sink, the curvature of the non-slip pad is consistent with the top of the heat sink, and the highest point of the non-slip pad is flush with the surface of the heat sink; the non-slip pad can provide better stability and anti-slip effect. When the heat sink is installed on the surface of the temperature equalizing plate, the non-slip pad can be in close contact with the plane of the temperature equalizing plate, increasing friction, thereby preventing the heat sink from sliding or shifting during use; in addition, since the highest point of the non-slip pad is flush with the surface of the heat sink, this helps to maintain the overall aesthetics of the heat sink, while ensuring that the heat sink maintains good contact with the heat-dissipated equipment during operation, thereby improving heat dissipation efficiency. The position of the anti-slip pad is installed in a symmetrical structure, and the contact between the anti-slip pad and the plane of the temperature equalizing plate is increased through two-point anti-slip, thereby increasing friction and further achieving an anti-slip effect.
[0017] Furthermore, the surface of the base is provided with a plurality of anti-slip grooves for increasing the friction of the base surface. The anti-slip grooves are linearly arranged on the outer side of the base, and the distance between two adjacent anti-slip grooves is equal. When the user's hand contacts the outer side of the base, the anti-slip grooves increase the contact points between the user's hand and the outer side of the base, 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.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. The through-hole design allows the heat dissipation holes to not only directly dissipate the heat inside the heat sink, but also increases the heat dissipation area with the help of the tooth-shaped structure of the placement slot, thereby improving heat dissipation performance. In addition, the through-holes help form air flow channels, promoting the exhaust of hot air and the intake of cold air, further enhancing the heat dissipation effect. This design enables the radiator to dissipate the heat generated by the vapor chamber more quickly and evenly, ensuring that the vapor chamber operates at a balanced temperature.
[0020] 2. By adopting the arrangement of tooth-shaped hollow placement grooves inside the heat sink, the heat sink is made into a thin sheet shape, thereby increasing its cooling effect. By evenly distributing the support plates on the surface of the base plate, the spaced support plates support the heat sink while avoiding affecting the heat dissipation effect of the heat sink.
[0021] 3. The inner wall of the heat sink is supported by the arc-shaped top of the support plate and several top blocks on the surface of the support plate. While increasing the force points, the original heat dissipation area is retained.

[0030] For this example, please refer to Figures 1-6 , a specific implementation of a temperature vapor chamber radiator includes a base 1, a heat sink 2 for dissipating heat, and a bottom plate 3. The base 1 and the heat sink 2 are an integrally formed structure. The interior of the heat sink 2 is a tooth-shaped hollow placement groove 6, which is linearly arranged on the surface of the base 1. The bottom plate 3 is a separate structure from the base 1 and the heat sink 2. One end of the bottom plate 3 is provided with a plurality of support plates 4 for supporting the heat sink 2.

[0032] By adopting the arrangement of the tooth-shaped hollow placement groove 6 inside the heat sink 2, the heat sink 2 is made into a thin sheet shape, thereby increasing its cooling effect. However, since the thin sheet is prone to deformation, a bottom plate 3 and a plurality of support plates 4 for supporting the heat sink 2 are added inside the placement groove 6. The support plates 4 are evenly distributed on the surface of the bottom plate 3. The spaced support plates 4 support the heat sink 2 while avoiding affecting the heat dissipation effect of the heat sink 2.
[0033] In addition, the inner wall of the heat sink 2 is supported by the arc-shaped top of the support plate 4 and several top blocks 5 on the surface of the support plate 4, which increases the force points while retaining the original heat dissipation area.

The surface of the reinforcing ribs 9 is provided with a plurality of flow holes 10 for assisting the gasification and circulation of the liquid. The flow holes 10 penetrate the surface of the two ends of the reinforcing ribs 9.
[0035] The design of the flow holes 10 running through the surfaces of both ends of the reinforcing ribs 9 can promote the vaporization process of the cooling liquid in the liquid storage tank 8. The flow holes 10 provide additional surface area for the liquid, thereby increasing the contact opportunities between the liquid and the surrounding environment, helping the liquid to absorb heat and convert into gas faster; in addition, the flow holes 10 can also help reduce the resistance to liquid flow, making the liquid more evenly distributed in the liquid storage tank 8, further improving the vaporization efficiency. The reinforcing ribs 9 provide structural support to ensure that the liquid storage tank 8 maintains a stable shape under the action of liquid pressure, while the flow holes 10 optimize the vaporization performance of the liquid without sacrificing structural strength.
[0036] The surface of the bottom plate 3 is provided with a plurality of air holes 11 for assisting the vaporization and circulation of the liquid. The air holes 11 pass through the surface of the bottom plate 3 and are connected to the interior of the liquid storage tank 8. The reinforcing rib 9 is located between two adjacent air holes 11; the reinforcing rib 9 can provide additional structural strength and rigidity to prevent the bottom plate 3 from deforming under pressure or temperature changes; in addition, the reinforcing rib 9 helps to disperse stress and reduce damage to the bottom plate 3 caused by the pressure generated by the vaporization of the liquid; at the same time, it can also help maintain the flatness of the bottom plate 3 and ensure the size and position accuracy of the air holes 11, thereby ensuring the efficiency and uniformity of the liquid vaporization and circulation.
[0037] The base 1 and the heat sink 2 are both made of aluminum; aluminum has a high thermal conductivity and can effectively conduct heat from the heat source to the heat sink 2, thereby improving the heat dissipation efficiency. In addition, the density of aluminum is low, which can make the overall weight of the base 1 and the heat sink 2 lighter, convenient for installation and transportation, while reducing the burden on the equipment. A dense oxide film is easily formed on the surface of the aluminum, which has a certain corrosion resistance and extends the service life of the heat dissipation system. In addition, aluminum is easy to process and shape, and heat sinks of various shapes and sizes can be designed according to the heat dissipation requirements to meet the heat dissipation requirements of different equipment, facilitate operator transportation and processing, and reduce manufacturing costs.
[0038] The top block 5 and the bottom plate 3 form an angle of 15°, and the top block 5 gradually converges toward the top of the support plate 4 along the 15° angle, and the top block 5 is triangular. The triangle is used as the supporting shape of the top block 5, so that the top block 5 has relative stability. This design helps to improve the stability of the overall structure. Moreover, through the inclined design of 15°, the top block 5 can better adapt to the shape of the heat sink 2 during the retraction process, thereby optimizing space utilization. At the same time, the force exerted by the heat sink 2 on the support plate 4 from top to bottom can be adapted to the force exerted by the heat sink 2 on the support plate 4 by forming an angle of 15°, thereby supporting the heat sink 2 and reducing the probability of deformation of the heat sink 2. In addition, the inclined design shape of 15° makes it easier to assemble the support plate 4, is easy to cooperate with the support plate 4, improves assembly efficiency, and facilitates installation.
