Description

Technical Field

[0001] The utility model belongs to the technical field of super heat conduction, and particularly relates to a plate-shaped super heat conduction element. Background Art

[0002] With the continuous increase in the power of electronic devices while the volume is required to be smaller and smaller, the heat generation per unit area has doubled, so the heat dissipation problem of high heat flux density devices has become one of the key technologies affecting the design and application of electronic devices. Compared with traditional heat dissipation methods, flat micro heat pipes have unique advantages such as high heat transfer efficiency, good temperature uniformity, flat outer surface, and simple structure, and have become one of the main methods to solve the heat dissipation problem of high heat flux density devices.

[0003] The existing flat micro heat pipes have the problem of large steam flow resistance, resulting in low heat transport capacity. Therefore, there is an urgent need to design a plate-shaped super heat conduction element that can ensure the reflux of liquid in the anti-gravity state while significantly reducing the steam flow resistance.

[0008] Further, the longitudinal section of the micro heat channel is rectangular.

[0009] Further, the strong capillary core is inserted into the micro heat channel.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Referring to Figure 1-2 , a plate-shaped ultra heat-conducting element includes a plate body 1. A plurality of micro heat channels are arranged side by side and at intervals inside the plate body 1. A strong capillary core 4 is installed inside each micro heat channel. Steam flow channels 5 are respectively arranged on both sides of the strong capillary core 4 inside the micro heat channel.

[0018] When a heat source generates heat energy, the liquid working medium near the heat source inside the strong capillary core 4 is heated and vaporized, and then diffuses rapidly to the condensation section through the steam flow channels 5 on both sides in a steam state for heat exchange. The steam flow channels 5 on both sides of the strong capillary core 4 can reduce the resistance of steam flow, thereby improving the heat transport capacity. The missing liquid working medium at the heat source can be automatically replenished under the action of capillary force, thereby realizing cyclic heat exchange.

[0019] In this embodiment, the plate-shaped ultra heat-conducting element is integrally formed by a mechanical extrusion process, and is formed by one-time encapsulation after removing non-condensable gases and filling the working medium.

[0020] In this embodiment, a plurality of micro heat channels are arranged at equal intervals inside the plate body 1, so as to ensure the uniformity of the heat dissipation capacity of each part of the plate-shaped ultra heat-conducting element.

[0021] In this embodiment, upper limit blocks 2 are fixedly connected to both sides of the strong capillary core 4 on the inner top wall of the micro heat channel, and lower limit blocks 3 are fixedly connected to both sides of the strong capillary core 4 on the inner bottom wall of the micro heat channel. The two upper limit blocks 2 and the two lower limit blocks 3 can limit and fix the strong capillary core 4 to prevent accidental deviation of the strong capillary core 4.

[0022] In this embodiment, the longitudinal section of the micro heat channel is rectangular.

[0023] In this embodiment, the strong capillary core 4 is formed by extrusion.

[0024] In this embodiment, the strong capillary core 4 is inserted into the micro heat channel, which facilitates the assembly between the strong capillary core 4 and the plate body 1.

[0025] In this embodiment, the strong capillary core 4 is made of porous foam metal or arranged by metal fibers.

[0026] In the present utility model, steam flow channels 5 are respectively arranged on both sides of the strong capillary core 4 inside the micro heat channel, which can not only ensure liquid reflux under anti-gravity conditions, but also ensure the flow of steam with lower resistance, thereby improving the heat transport capacity of the plate-shaped super heat conducting element.

[0027] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
