Description

Technical Field

[0001] This utility model relates to the field of temperature equalization plate technology, and in particular to a novel temperature equalization plate. Background Technology

[0002] A vapor chamber, also known as a heat pipe, is a heat pipe technology that utilizes the principle of phase change heat transfer. It transfers heat by filling a sealed vacuum chamber with a certain amount of working fluid, and through the evaporation, gas flow, and condensation processes of the working fluid.

[0003] With the rapid development of technology, the integration and performance of electronic components are increasing day by day, leading to a continuous increase in power consumption and a more severe heat dissipation problem. As an important heat dissipation component, vapor chambers play a crucial role in the heat dissipation of electronic devices. However, current vapor chambers on the market still have certain limitations in heat transfer performance, with high heat transfer losses, a tendency for dry burning at the heat source, and the inability of the heat source to function properly.

[0004] Therefore, a new type of heat spreader is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a novel heat spreader to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A novel heat spreader includes a substrate and a heating element:

[0007] The substrate has an interior cavity, and the interior cavity has multiple spacers, which divide it into multiple heat-conducting chambers. Each heat-conducting chamber is equipped with a heating element on its exterior.

[0008] The substrate has a vertical state and a horizontal state;

[0009] When the substrate is in a vertical position, the heating element is located in the lower part of the heat-conducting chamber;

[0010] When the substrate is in a horizontal state, the heating element is located in the middle of the heat conduction chamber.

[0011] In some embodiments, the spacer portion is a reinforcing rib.

[0012] In some embodiments, the included angle between the inner walls of the first cavity and the second cavity both have an arc-shaped transition portion.

[0013] In some embodiments, a cover plate for sealing the first cavity and the second cavity is welded to one side of the substrate.

[0014] The cover plate is a heat dissipation fin.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model divides the entire heat spreader structure by using a partition, which strengthens the heat spreader structure, improves its modality, and forms two or more cavities to improve dry-burning capability. By placing the main heat source in the middle, upper and bottom of each partition space, it ensures that dry burning will not occur at each heat source and that the heat source can work normally, thereby reducing heat transfer loss.

[0017] Second, by setting the included angle between the inner walls of the first cavity and the second cavity to an arc transition, this utility model can increase the surface area of ​​the inner walls of the first cavity and the second cavity, providing more contact surface for the evaporation and condensation of the working fluid, thereby enhancing the heat transfer efficiency. Moreover, compared with the right angle design, the arc design has higher structural strength when subjected to external pressure or vibration, and can resist greater deformation and damage, thus enhancing the durability and reliability of the heat spreader.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Therefore, features specified with terms such as "first" or "symmetric" may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, this embodiment of the present invention provides a novel heat spreader, comprising a substrate 1 and a heating element 3:

[0030] The substrate 1 has a cavity inside, and the cavity has a plurality of spacers 13, which are divided into a plurality of heat-conducting chambers. Each heat-conducting chamber is provided with a heating element 3 on its exterior.

[0031] The substrate 1 has a vertical state and a horizontal state;

[0032] When the substrate 1 is in a vertical position, the heating element 3 is located in the lower part of the heat conduction chamber;

[0033] When the substrate 1 is in a horizontal state, the heating element 3 is located in the middle of the heat conduction chamber.

[0034] In some embodiments, the spacer 13 is a reinforcing rib.

[0035] In some embodiments, the included angle between the inner walls of the first cavity 11 and the second cavity 12 has an arc-shaped transition portion.

[0036] In some embodiments: a cover plate 2 for sealing the first cavity 11 and the second cavity 12 is welded to one side of the substrate 1.

[0037] like Figure 3-4 As shown, multiple heat-conducting chambers are divided into a first cavity 11 and a second cavity 12 by a partition 13. In actual use, the number of partitions 13 can be set according to the actual situation. The existing heat spreader only has one cavity inside, and the modality in the middle position is very poor. By adding partitions 13, i.e. reinforcing ribs, the structure is strengthened, the modality is improved, and two cavities are formed at the same time, which improves the dry burning capacity.

[0038] More specifically, the partition 13 is a partition structure, mainly used to divide the entire heat spreader structure. By placing the main heat source in the middle, lower and bottom of each partition space, it ensures that each heat source will not dry out and that the heat source can work normally, thereby reducing heat transfer loss.

[0039] In this embodiment, specifically, as shown in... Figure 4 As shown, the included angle between the inner walls of the first cavity 11 and the second cavity 12 has an arc-shaped transition portion, which increases the surface area of ​​the inner walls of the first cavity 11 and the second cavity 12, providing more contact surface for the evaporation and condensation of the working fluid, thereby enhancing the heat transfer efficiency.

[0040] In this embodiment, specifically: a cover plate 2 for sealing the first cavity 11 and the second cavity 12 is welded to one side of the substrate 1.

[0041] In this embodiment, specifically: the cover plate 2 is a heat dissipation fin, which can further improve heat dissipation efficiency.

[0042] When this utility model is in operation: by using the partition 13 to divide the entire heat spreader structure, by placing the main heat source in the middle, lower and bottom of each partition space, it is ensured that each heat source will not dry burn and that the heat source can work normally, thereby reducing heat transfer loss. The partition cavity reduces the effect of capillary force of the liquid inside working against gravity, thereby improving heat transfer performance.

[0043] By setting the included angle between the inner walls of the first cavity 11 and the second cavity 12 to be arc-shaped, the surface area of ​​the inner walls of the first cavity 11 and the second cavity 12 can be increased, providing more contact surface for the evaporation and condensation of the working fluid, thereby enhancing the heat transfer efficiency. Moreover, compared with the right angle design, the arc-shaped design has higher structural strength when subjected to external pressure or vibration, and can resist greater deformation and damage, thus enhancing the durability and reliability of the heat spreader.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
