Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures, in particular to a temperature homogenizing plate. Background Art

[0002] The temperature equalizing plate includes an upper cover and a lower cover, and an inner cavity is set on each of the upper cover and the lower cover. When the upper cover and the lower cover are buckled together, the two inner cavities are combined to form a receiving space, which is used to accommodate the liquid medium and conduct temperature through the liquid medium.

[0003] In actual applications, when the lower cover is arranged downward, it not only has to bear the pressure of the upper cover, but also the pressure of other components; and the temperature plate also needs to conduct temperature. Therefore, the direct buckling of the upper cover and the lower cover in the existing technology is prone to collapse and other deformations after long-term use.

[0004] In order to overcome this problem in the prior art, copper pillars are usually added to the accommodation space to support the upper and lower covers. During the specific production process, the copper pillars need to be placed manually. After the copper pillars are placed, the upper cover is covered. This can easily cause the copper pillars to fall during operation and transportation, reducing the stability of the temperature spreader.

[0005] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0035] The embodiments of the present application will be described hereinafter with reference to the drawings and preferred embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the contents disclosed in the present specification. The present application can also be implemented or applied by other different specific embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the protection scope of the present application.

[0036] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and only show the components related to the present application in the drawings, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component when actually implemented can be arbitrarily changed, and the component layout pattern can also be more complex.

[0037] The present application provides a uniform temperature plate, such as Figure 1 , Figure 2 and Figure 3As shown, the uniform temperature plate comprises an upper cover 1, a lower cover 2, a plurality of first support columns 3 and a plurality of second support columns 4; the upper cover 1 has a first inner cavity 10, and the first support columns 3 are arranged in the first inner cavity 10; the lower cover 2 has a second inner cavity 20 and is used for being buckled with the upper cover 1; the second support columns 4 are arranged in the second inner cavity 20; the first support columns 3 correspond to the second support columns 4 one by one; when the upper cover 1 is buckled with the lower cover 2, the first support columns 3 and the second support columns 4 are in close contact (as shown in Figure 5

[0038] Specifically, the upper cover 1 and the lower cover 2 both have inner cavities, the inner cavity of the upper cover 1 is the first inner cavity 10, and the inner cavity of the lower cover 2 is the second inner cavity 20; when the upper cover 1 is buckled with the lower cover 2, the first inner cavity 10 corresponds to the second inner cavity 20 and forms a containing space of liquid medium.

[0039] The first support columns 3 are located in the first inner cavity 10 and arranged on the side of the upper cover 1 facing the lower cover 2; the second support columns 4 are located in the second inner cavity 20 and arranged on the side of the lower cover 2 facing the upper cover 1; when the upper cover 1 is buckled with the lower cover 2, the first support columns 3 and the second support columns 4 correspond to each other and are in close contact, thereby forming a support structure between the upper cover 1 and the lower cover 2, supporting the upper cover 1 and the lower cover 2 and avoiding the upper cover 1 and / or the lower cover 2 from being deformed in use. Since the first support columns 3 are directly arranged on the upper cover 1 and the second support columns 4 are directly arranged on the lower cover 2, the support structure can be formed by buckling the upper cover 1 with the lower cover 2, without manually placing the support columns as in the prior art, thereby reducing the production process; the fixed connection of the first support columns 3 with the upper cover 1 and the fixed connection of the second support columns 4 with the lower cover 2 make the support structure of the uniform temperature plate not deviate in use.

[0040] Therefore, the uniform temperature plate in the present application can avoid the deviation of the support structure and improve the overall stability of the uniform temperature plate by arranging the first support columns 3 on the upper cover 1 and the second support columns 4 on the lower cover 2, and enabling the first support columns 3 to be in close contact with the second support columns 4 and form a support structure when the upper cover 1 is buckled with the lower cover 2, thereby avoiding manual placement of the support columns and reducing the production process.

[0041] ​It should be noted that in this application, the first support column 3 and the second support column 4 are respectively arranged on the upper cover 1 and the lower cover 2, and the support structure is formed by the corresponding fit of the first support column 3 and the second support column 4, rather than directly designing the support structure on one of the covers. This avoids stress concentration caused by the load of the overall support structure being concentrated on one side; especially under the action of thermal expansion or external forces, if the load is concentrated on one side, it is easy to cause structural deformation or damage. By arranging the first support column 3 and the second support column 4 on the upper cover 1 and the lower cover 2 respectively, the load can be shared more evenly, improving the overall stability and durability of the vapor chamber.

[0042] At the same time, under hot operating conditions, various parts of the vapor chamber will experience thermal expansion. Providing the first support column 3 and the second support column 4 on the upper cover 1 and the lower cover 2, respectively, can prevent thermal stress from concentrating on one side, thereby reducing the risk of deformation or failure. Furthermore, providing the first support column 3 and the second support column 4 on the upper cover 1 and the lower cover 2, respectively, allows them to support and cooperate with each other after assembly, creating a more uniform compression effect, helping to improve the seal between the upper cover 1 and the lower cover 2 and prevent leakage of liquid media.

[0043] In one embodiment of the present application, the first support column 3 and the upper cover 1 are an integrally formed structure, and the second support column 4 and the lower cover 2 are an integrally formed structure.

[0044] In this embodiment, when producing the upper cover 1 and the lower cover 2, the first support column 3 is integrally formed on the upper cover 1 through extrusion or other processes, and the second support column 4 is integrally formed on the lower cover 2, so that the first support column 3 and the upper cover 1 are an integrally formed structure, and the second support column 4 and the lower cover 2 are an integrally formed structure, further improving the stability of the support structure in the accommodating space, avoiding skew and deviation of the support structure, and thus improving the overall stability of the temperature dispersion plate.

[0045] Since the upper cover 1 and the lower cover 2 are subjected to different stress conditions during operation, in one embodiment of the present application, the diameter of the first support column 3 is not equal to the diameter of the second support column 4 .

[0046] In this embodiment, an implementation method is as follows: Figure 5 As shown, the diameter of the first support column 3 is smaller than the diameter of the second support column 4 .

[0047] Specifically, the lower cover 2 usually bears more structural loads and supporting functions, so the diameter of the second support column 4 is larger to enhance the supporting force and pressure resistance; and since the first support column 3 is mainly used for connection and sealing, the force on the upper cover 1 is relatively small, therefore, the diameter of the first support column 3 can be designed to be smaller, thereby saving materials.

[0048] Because the upper cover 1 and lower cover 2 behave differently during thermal expansion, the different diameters of the first and second support columns 3 and 4 can better accommodate this differential expansion. The larger diameter of the second support column 4 can withstand more thermal stress, while the smaller diameter of the first support column 3 allows for more flexibility in adapting to structural changes, reducing the risk of deformation caused by thermal expansion.

[0049] In addition, the diameter of the second support column 4 is larger than that of the first support column 3, thereby providing a certain amount of misalignment redundancy for the corresponding cooperation between the first support column 3 and the second support column 4, reducing the alignment error between the first support column 3 and the second support column 4, and ensuring a more efficient assembly process.

[0050] In one embodiment of this application, Figure 5 As shown, the height of the first support column 3 is smaller than the height of the second support column 4 .

[0051] Specifically, the axial end face of the first support column 3 does not extend beyond the surface of the upper cover 1, while the axial end face of the second support column 4 extends beyond the surface of the lower cover 2. The height of the first support column 3 is smaller than the height of the second support column 4, so that when the upper cover 1 and the lower cover 2 are buckled together, the first support column 3 and the second support column 4 can fit together to form a support structure.

[0052] Since the lower cover 2 needs to withstand the pressure from the upper cover 1 and the pressure of the liquid medium inside the accommodating space, the height of the second support column 4 is designed to be longer so that the second support column 4 can enhance the stability of the overall structure and reduce deformation caused by external force or temperature changes.

[0053] At the same time, the longer second support column 4 can increase the contact area between the overall structure of the lower cover 2 and the liquid medium, thereby increasing the heat dissipation area, promoting the dissipation of heat to the environment, and improving the heat dissipation efficiency.

[0054] like Figure 1 、 Figure 2 and Figure 4As shown, the upper cover 1 comprises an upper cover body 11 and a first extension 12; the first inner cavity 10 is arranged on the upper cover body 11; the first extension 12 is arranged on the side of the upper cover body 11; a first drainage groove 13 is arranged on the first extension 12, one end of the first drainage groove 13 communicates with the first inner cavity 10, and the other end is used for communicating with an external liquid supply source.

[0055] As shown in Figure 1 and Figure 3 As shown, the lower cover 2 comprises a lower cover body 21 and a second extension 22; the second inner cavity 20 is arranged on the lower cover body 21; the second extension 22 is arranged on the side of the lower cover body 21; a second drainage groove is arranged on the second extension 22, one end of the second drainage groove communicates with the second inner cavity 20, and the other end is used for communicating with an external liquid supply source; when the upper cover 1 is buckled with the lower cover 2, the first drainage groove 13 corresponds to the second drainage groove and encloses to form a liquid injection channel 100 (as shown in Figure 1 ).

[0056] Specifically, the first support column 3 is arranged on the upper cover body 11 and located in the first inner cavity 10; the first extension 12 extends outward from the side of the upper cover body 11. The second support column 4 is arranged on the lower cover body 21 and located in the second inner cavity 20; the second extension 22 extends outward from the side of the lower cover body 21. The first extension 12 corresponds to the second extension 22, the first drainage groove 13 corresponds to the second drainage groove, and when the upper cover 1 is buckled with the lower cover 2, the upper cover body 11 is buckled with the lower cover body 21, the first inner cavity 10 communicates with the second inner cavity 20, and the first drainage groove 13 communicates with the second drainage groove and encloses to form a liquid injection channel 100.

[0057] The containing space enclosed by the first inner cavity 10 and the second inner cavity 20 communicates with the external liquid supply source through the liquid injection channel 100, so that liquid medium is injected into the containing space through the liquid injection channel 100 to perform heat exchange.

[0058] It should be noted that the upper cover 1 and the lower cover 2 are buckled and connected and sealed between each other through a diffusion welding process after buckling. After the liquid medium in the containing space is injected, the inlet of the liquid injection channel 100 corresponding to the containing space is plugged, and the first extension 12 and the second extension 22 are broken, so that the uniform temperature plate can be installed into the electronic equipment to perform heat exchange.

[0059] In an embodiment of the present application, as shown in Figure 4As shown, the distribution density of the first support columns 3 close to the first drainage groove 13 is greater than the distribution density of the first support columns 3 far from the first drainage groove 13 .

[0060] Specifically, the distribution density of the first support columns 3 is larger near the entrance of the injection channel 100 in the accommodating space, and the distribution density of the first support columns 3 is smaller away from the entrance of the injection channel 100; similarly, for the second support columns 4, the distribution density near the injection channel 100 is greater than the distribution density away from the injection channel 100.

[0061] In this embodiment, a denser support structure is designed near the injection channel 100. This helps create a drainage effect through the support structure, guiding the incoming liquid for even distribution, thereby ensuring smoother liquid flow within the vapor chamber and avoiding dead zones. Furthermore, by increasing the number of support structures near the injection channel 100, the structural strength of this area can be further enhanced, resisting the pressure caused by the liquid flow and preventing deformation or rupture. It can also disperse pressure from the fluid flow or the external environment, reducing local stress concentration and improving the reliability of the overall structure.

[0062] In one embodiment of the present application, the width of the first drainage groove 13 at one end close to the upper cover body 11 is smaller than the width of the first drainage groove 13 at one end away from the upper cover body 11 .

[0063] Specifically, the width of the first drainage groove 13 near one end of the accommodating space is smaller, and the width of the first drainage groove 13 near one end of the external liquid supply source is larger, so that when liquid is supplied, the liquid flows from the wide part to the narrow part, and then enters the accommodating space, helping to guide the liquid into the accommodating space faster and reducing the risk of liquid being retained in the injection channel 100.

[0064] At the same time, the widening and narrowing design of the injection channel 100 can control the flow rate of the liquid, making the liquid more efficient and faster during the injection into the receiving space; the narrow design of the injection channel 100 near the receiving space can increase the speed of liquid flow, reduce the formation of bubbles in the injection channel 100, ensure the purity of the liquid in the receiving space, and avoid the formation of bubbles in the liquid that affect heat conduction.

[0065] like Figure 6 As shown, the first drainage groove 13 includes a first groove body 131 and a second groove body 132. The first groove body 131 and the second groove body 132 are coaxially arranged; the second groove body 132 is located between the first groove body 131 and the upper cover body 11, and the inner diameter of the first groove body 131 is larger than the inner diameter of the second groove body 132. Similarly, the structure of the second drainage groove is the same as that of the first drainage groove 13.

[0066] In one embodiment of this application, Figure 6 As shown, a first groove 5 is provided on the upper cover body 11, and the first extension portion 12 is located in the first groove 5 and is gap-matched with the side wall of the first groove 5; a second groove is provided on the lower cover body 21, and the second extension portion 22 is located in the second groove and is gap-matched with the side wall of the second groove.

[0067] In this embodiment, the first groove 5 is used to make way for the first extension 12, reducing the contact area between the first extension 12 and the upper cover body 11, making it easier to break the first extension 12 after liquid injection. Similarly, the second groove is used to make way for the second extension 22, reducing the contact area between the second extension 22 and the lower cover body 21, making it easier to break the second extension 22 after liquid injection.

[0068] In one embodiment of the present invention, the first groove 5 and the second groove are both trapezoidal grooves; an opening is provided at the bottom of the trapezoidal groove for the first extension portion 12 and the second extension portion 22 to pass through; the upper bottom 51 of the trapezoidal groove (such as Figure 6 As shown) are connected to the first extension portion 12 and the second extension portion 22 respectively.

[0069] Specifically, the trapezoidal groove is an isosceles trapezoidal groove, and the two sides 52 (such as Figure 6 As shown in the figure, there is a gap between the first extension part 12 and the second extension part 22, and after the first extension part 12 and the second extension part 22 pass through the opening, they are connected to the upper bottom 51 of the trapezoidal groove, thereby reducing the contact area between the first extension part 12 and the upper cover body 11 as much as possible, and reducing the contact area between the second extension part 22 and the lower cover body 21, so that the first extension part 12 and the second extension part 22 can be easily broken after the liquid injection is completed.

[0070] In summary, the present application provides a temperature equalizing plate, which includes: an upper cover having a first inner cavity; a plurality of first support columns arranged in the first inner cavity; a lower cover having a second inner cavity and being used to buckle with the upper cover; a plurality of second support columns arranged in the second inner cavity; the first support columns and the second support columns correspond one to one; when the upper cover and the lower cover are buckled together, the first support columns and the second support columns are in contact with each other. The temperature equalizing plate described in the present application, by setting the first support columns on the upper cover and the second support columns on the lower cover, can be fitted with the second support columns to form a support structure when the upper cover and the lower cover are buckled together, thereby avoiding the skew and deviation of the support structure while avoiding the manual placement of support columns and reducing the production process, thereby improving the overall stability of the temperature equalizing plate.
