[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0033] The following describes a biomimetic radiator according to an embodiment of the present invention.

[0034] like Figures 1 to 3As shown, the bionic heat sink of this embodiment includes a cooling plate. Bionic flow channels are formed inside the cooling plate, and liquid inlet holes 121 and liquid outlet holes 122 communicating with the bionic flow channels are formed on the side of the cooling plate. The bionic flow channels are formed in a tree-like or honeycomb shape. The upper or lower surface of the cooling plate is used to connect chips.

[0035] like Figure 1 As shown, the cooling plate of this application has a liquid inlet 121 and a liquid outlet 122. Coolant can enter the biomimetic flow channel through the liquid inlet 121 and then flow out through the liquid outlet 122, thereby cooling the cooling plate. A chip is connected to the surface of the cooling plate, and the low temperature of the cooling plate can cool the chip, thereby maintaining the chip's continuous and stable operation.

[0036] The tree-like or honeycomb-like biomimetic flow channels, inspired by trees and honeycombs in nature, can achieve high heat dissipation efficiency and effectively cool the chip.

[0037] In some embodiments of this utility model, the cooling plate includes a base plate 100, a plurality of baffles, and a cover plate 400. The base plate 100 has a groove 110, with an inlet hole 121 and an outlet hole 122 formed at its longitudinal ends. The baffles are spaced apart at the bottom of the groove 110, with a predetermined distance between them. The gaps between adjacent baffles and between the baffles and the sidewalls of the groove 110 form biomimetic flow channels. The cover plate 400 connects to the upper surface of the base plate 100 and covers the groove 110. The longitudinal top surface of the baffles is flush with the upper surface of the base plate 100.

[0038] A base plate 100 with a groove 110 can be formed by CNC machining on the substrate, and multiple blocks are provided at the bottom of the groove 110. The gaps between adjacent blocks and the gaps between the blocks and the sidewalls of the groove 110 form a biomimetic flow channel. The manufacturing process is relatively simple and meets the needs of mass production.

[0039] The cover plate 400 is connected to the upper surface of the base plate 100 and covers the groove 110, so that the coolant in the cooling plate can only flow in the biomimetic flow channel.

[0040] The following specific examples illustrate a biomimetic heat sink with a tree-shaped biomimetic flow channel.

[0041] The biomimetic flow channel is formed in a tree shape, with the baffles including at least two first baffles 210 and at least one second baffle 220. Adjacent first baffles 210 are spaced laterally apart, and the first baffles 210 are distributed longitudinally, forming n continuous segments, where n is greater than or equal to 3. The width of each first baffle 210 decreases progressively from its bottom to its top longitudinally. The second baffle 220 is positioned in the middle between two adjacent first baffles 210, and is distributed longitudinally, forming n-1 continuous segments. The position of the first segment of the second baffle 220 corresponds to the position of the second segment of the first baffle 210, and the top longitudinal point of the second baffle 220 is flush with the top longitudinal point of the first baffle 210.

[0042] like Figure 2 As shown, n equals 3, meaning the first baffle 210 comprises three consecutive segments, each with a gradually decreasing width. The second baffle 220 is positioned between two adjacent first baffles 210, comprising two consecutive segments with gradually decreasing widths. The first segment of the second baffle 220 corresponds to the second segment of the first baffle 210, and the second segment of the second baffle 220 corresponds to the third segment of the first baffle 210. Coolant enters the biomimetic flow channel through the inlet hole 121, flows from the bottom of the first baffle 210's longitudinal direction to the top of the first baffle 210's longitudinal direction, and finally flows out through the outlet hole 122. Because the contact area between the coolant and the baffles increases segment by segment, the heat dissipation efficiency for the chip increases segment by segment. Corresponding to higher initial coolant temperatures and lower cooling efficiency as temperatures rise, this increases the uniformity of heat dissipation for the chip. Furthermore, this cooling plate structure effectively disperses heat and reduces localized temperatures, making it particularly suitable for large-area heat dissipation scenarios.

[0043] It should be noted that the above are just optional examples, and n can also be 4, 5, 6, etc., all of which should be understood within the scope of this utility model.

[0044] Furthermore, the stop block also includes at least two third stop blocks 230. The two third stop blocks 230 are respectively disposed in two gaps between the second stop block 220 and the two first stop blocks 210 adjacent to its two lateral sides. The third stop blocks 230 are distributed longitudinally and form continuous n-2 segments. The position of the first segment of the third stop block 230 corresponds to the position of the second segment of the second stop block 220, and the longitudinal top end of the third stop block 230 is flush with the longitudinal top end of the first stop block 210.

[0045] like Figure 2 As shown, n equals 3, meaning the third block 230 is positioned between the third segment of the first block 210 and the second segment of the second block 220, thereby making the bionic flow channel denser segment by segment, that is, increasing the contact area with the coolant segment by segment, and further improving the uniformity of heat dissipation for the chip.

[0046] It should be noted that the above are just optional examples, and n can also be 4, 5, 6, etc., all of which should be understood within the scope of this utility model.

[0047] Furthermore, adjacent segments of the first stop block 210 and the second stop block 220 are connected by a connecting plate with a trapezoidal cross-section.

[0048] like Figure 2 As shown, adjacent segments of the first block 210 are connected by trapezoidal connecting blocks, and adjacent segments of the second block 220 are connected by trapezoidal connecting blocks.

[0049] The connecting blocks reduce right angles in the bionic flow channel, increasing the smoothness of coolant flow.

[0050] The following specific embodiments illustrate a biomimetic heat sink with honeycomb-shaped biomimetic flow channels.

[0051] The biomimetic flow channel is formed in a honeycomb shape, and the baffle includes multiple wing blocks 300, which are arranged in multiple rows and columns at intervals, and the wing blocks 300 are formed in a hexagonal shape.

[0052] The cooling plate comprises multiple hexagonal fins 300, exhibiting high symmetry and stability.

[0053] The cooling plate of this structure has a large surface area, which effectively increases the contact between the fluid and the chip, optimizes the heat exchange efficiency, and has good structural rigidity, making it suitable for withstanding high thermal stress.

[0054] Furthermore, the liquid inlet 121 and the liquid outlet 122 are located at opposite corners of the groove 110.

[0055] This increases the travel distance of the coolant flow and improves heat dissipation efficiency.

[0056] Furthermore, the transverse sidewalls of the groove 110 are formed with grooves 111, which are arranged around the three sides of the adjacent fin block 300.

[0057] This increases the contact area of ​​the coolant and improves heat dissipation efficiency.

[0058] In some embodiments of this invention, the cooling plate is formed as an aluminum plate or a copper plate.

[0059] Copper and aluminum have high thermal conductivity, which enables them to provide high heat dissipation efficiency for chips.

[0060] In some embodiments of this utility model, the base plate 100 and the cover plate 400 are brazed together.

[0061] The brazing connection between the base plate 100 and the cover plate 400 ensures a stable connection between them, increases sealing, and prevents leakage.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
