Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an integrated 3D heat spreader for the powder tube. Background Technology

[0002] Compared to the one-dimensional heat conduction effect of traditional heat pipes, vapor chambers typically offer two-dimensional heat conduction. Three-dimensional vapor chambers, however, further enhance this by achieving three-dimensional heat conduction through a phase-change flow field in the medium. Structurally, a three-dimensional vapor chamber primarily consists of an outer shell, a medium, and a wick. The unique three-dimensional structure and capillary microchannels of the wick enable efficient phase-change heat transfer of the medium flowing within it, significantly improving heat dissipation capacity. It is currently widely used in high-end laptops, AI computing power, data center servers, workstations, and other fields, effectively solving the heat dissipation challenges of these electronic devices. However, with the continuous increase in the power heat flux density of electronic devices, existing three-dimensional vapor chamber structures have revealed numerous technical challenges.

[0003] Currently, the conventional method for 3D vapor chambers is to combine powder rings with the vapor chamber, or to combine copper tube powder with the vapor chamber. The liquid return path is copper tube powder → powder ring → vapor chamber, which has high resistance and results in low performance. In addition, this combination method involves more processes, has a lower capillary yield, and higher production costs. Utility Model Content

The lower copper mesh is attached to or close to the lower cover of the heat spreader plate in the sealed cavity. The heat source powder ring is located in the sealed cavity within the range corresponding to the heat source contact portion.

[0010] Furthermore, the copper tube powder and the powder ring have a connected internal channel, and the lower end of the powder ring seat is provided with a notch, which connects the powder ring seat and the internal channel of the copper tube powder.

[0011] Furthermore, the notches are arranged in a symmetrical or circular array.

[0012] Furthermore, the heat source contact portion is a convex bulge, which forms a groove in the sealed cavity, and the heat source powder ring is located in the groove.

[0013] Furthermore, the heat source powder ring includes a powder column and a powder ring surrounding the powder column, wherein the lower end of the powder column is flush with the powder ring and the upper end protrudes outside the powder ring.

[0014] Furthermore, the sealed cavity is also provided with several copper pillars, which support the upper cover of the heat exchange plate and the lower cover of the heat exchange plate.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of an integrated 3D heat spreader for powder tubes, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit its scope.

[0032] Please refer to Figures 1-7 A powder pipe integrated 3D heat spreader, comprising:

[0033] The top of the heat spreader plate is 100°C.

[0034] The lower cover 200 of the heat exchange plate is connected to the upper cover 100 of the heat exchange plate and forms a sealed cavity 210. The lower cover 200 of the heat exchange plate has a heat source contact part 211 on the side facing away from the upper cover 100 of the heat exchange plate.

[0035] The copper tube 300 is connected to the top cover 100 of the heat exchange plate and communicates with the sealed cavity 210.

[0036] The internal capillary structure includes at least one upper copper mesh 410, at least one lower copper mesh 420, at least one heat source powder ring 430, and at least one integrated powder tube structure 440. The integrated powder tube structure 440 includes a copper tube powder 441 and a powder ring seat 442 sintered together. The copper tube powder 441 extends from the copper tube 300 into the sealed cavity 210. The powder ring seat 442 is located in the sealed cavity 210 and is sintered or welded to the lower copper mesh 420. The upper copper mesh 410 is attached to or close to the upper cover 100 of the heat spreader plate in the sealed cavity 210. The lower copper mesh 420 is attached to or close to the lower cover 200 of the heat spreader plate in the sealed cavity 210. The heat source powder ring 430 is located in the sealed cavity 210 within the range corresponding to the heat source contact portion 211.

[0037] The integrated powder tube structure 440 is adopted, and the copper tube powder 441 and powder ring seat 442 are sintered in one step, which reduces the number of processes and lowers the cost. The integrated powder tube structure 440 is directly sintered or welded to the lower cover copper mesh 420, which reduces the liquid backflow path, lowers the liquid pressure difference, and improves the performance.

[0038] Please refer to Figure 1 , Figure 4 and Figure 5 The copper tube powder 441 and the powder ring 431 have a connected internal channel 443. The lower end of the powder ring seat 442 is provided with a notch 4421, which connects the powder ring seat 442 and the internal channel 443 of the copper tube powder 441. The notch 4421 facilitates steam flow, thereby further improving performance.

[0039] Preferably, the notches 4421 are arranged in a symmetrical or ring array. This ensures not only uniform gas flow but also smoother gas flow, especially with the horizontally penetrating notches 4421.

[0040] Please refer to Figure 2 and Figure 7 The heat source contact portion 211 is a convex bulge, which forms a groove 212 within the sealed cavity 210. The heat source powder ring 430 is located within the groove 212. Typically, the convex bulge is located in the middle.

[0041] Please refer to Figures 1-3The heat source powder ring 430 includes a powder column 432 and a powder ring 431 that surrounds the powder column 432. The lower end of the powder column 432 is flush with the powder ring 431, and the upper end protrudes outside the powder ring 431. Preferably, the upper end of the powder column 432 abuts against the top cover 100 of the heat spreader plate, and the upper end of the powder ring 431 abuts against the copper mesh 410 of the top cover.

[0042] Please refer to Figures 1-3 The sealed cavity 210 is also equipped with several copper pillars 450, which support the upper cover 100 of the heat exchange plate and the lower cover 200 of the heat exchange plate.

[0043] Preferably, the copper pillar 450, the lower cover copper mesh 420, and the heat source powder ring 430 are all welded to the lower cover 200 of the heat exchange plate.

[0044] Preferably, the upper copper mesh 410 is welded to the upper cover 100 of the heat spreader plate. The sealing connection between the upper cover 100 and the lower cover 200 of the heat spreader plate is also generally welded, but sintering can also be performed as needed.

[0045] Please refer to Figure 1 , Figure 5 and Figure 6 The outer diameter of the powder ring seat 442 is larger than the outer diameter of the copper tube powder 441. This increases the contact area between the powder ring seat 442 and the lower cover copper mesh 420, while also preventing unstable connection caused by the notch 4421.

[0046] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0048] In summary, the integrated powder tube 3D heat spreader provided by this utility model adopts an integrated powder tube structure, in which the copper tube powder and powder ring seat are sintered in one step, reducing the number of processes and lowering the cost; the integrated powder tube structure is directly sintered or welded to the copper mesh of the lower cover, reducing the liquid backflow path, lowering the liquid pressure difference, and improving performance.
