Description

Technical Field

[0001] The utility model relates to the technical field of thermal management, in particular to a fin assembly and a liquid cooling plate. Background Art

[0002] In traditional fin assembly design, common problems are inconvenient assembly and insufficient stability, especially in scenarios that require high heat exchange efficiency and adapt to special space layout requirements. Previous fin structures often rely on simple stacking or screw fixing, which is not only cumbersome and time-consuming to assemble, but also prone to misalignment or even loosening of fins during long-term operation due to vibration, thermal expansion and contraction, thus affecting heat exchange efficiency and the overall durability of the equipment.

[0003] For example, some early fin assembly designs used vertical stacking, with each fin held in place by an external clamp or adhesive, which increased the weight and cost of the assembly, while also limiting the flow path of the heat exchange medium and reducing heat transfer efficiency. In addition, the fin arrangement lacking an effective positioning and support mechanism is more susceptible to deformation in high temperature and high pressure environments, shortening its service life.

[0004] In addition, for heat exchange systems that need to flexibly adapt to different spatial layouts, such as compact or special-shaped heat exchangers, traditional fin assemblies are difficult to achieve efficient space utilization and customization requirements due to the limitations of their fixed structures, thus limiting their scope of application.

[0005] It can be seen that the fin assembly in the prior art has the problem of insufficient stability between the fins during assembly and use. Utility Model Content

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0034] In order to solve the problem of insufficient stability between fins in the fin assembly in the prior art during assembly and use, the utility model provides a fin assembly and a liquid cooling plate.

[0035] like Figure 1-7 As shown, the utility model provides a fin assembly, comprising a plurality of first fins 1 and second fins 2 alternately stacked, wherein the first fin 1 has two first sides arranged opposite to each other, each first side is provided with a downwardly opening ear 11 and a support portion 12 passing through the ear. It can be understood that the support portion 12 is extended from the first side in a direction away from the first fin 1.

[0036] It should be noted that the number of the hanging ears 11 arranged on each first side and the supporting parts 12 in the hanging ears can be multiple.

[0037] Furthermore, the second fin 2 has two second sides arranged corresponding to each first side, and each second side is provided with an abutment portion 21 corresponding to the support portion 12. It can be understood that the number of abutment portions 21 arranged on each second side can also be multiple, but the number of abutment portions 21 arranged on the second side is equal to the number of support portions 12 arranged on the first side corresponding to the second side, so that each support portion 12 can correspond to each abutment portion 21 one by one and abut against each other.

[0038] When stacked, each first fin 1 located below has an adjacent first fin 1 above, and the ear 11 of the first fin 1 below partially or completely penetrates into the ear of the first fin 1 adjacent above and abuts against it, and the supporting portion 12 of the first fin adjacent above is penetrated into the ear 11 of the first fin below, so that the nesting of two adjacent first fins 1 can be achieved in the up and down directions.

[0039] In the present utility model, if Figure 2 , 7, the height direction is the direction of the z-axis in the figure. The x-axis usually represents the length direction of the fin, and the y-axis usually represents the width direction of the fin.

[0040] Furthermore, one of the second fins 2 is inserted between the two first fins 1 , and the abutting portion 21 of the second fin 2 is inserted into the hanging ear 11 of the lower first fin and abuts against the supporting portion 12 of the first fin.

[0041] Furthermore, another second fin 2 is provided on the upper adjacent first fin 1, and its abutment portion 21 penetrates into the upper adjacent first fin's hanging ear 11 and abuts against the abutment portion 12 of the first fin. The abutment portion 21 of the second fin simultaneously penetrates into the hanging ear 11 of the lower first fin and abuts against the upper side of the ear wall of the hanging ear 11.

[0042] Through the above arrangement, the first fins 1 and the second fins 2 are stacked alternately, the ears 11 of the two adjacent first fins are nested and matched, and the abutment portion 21 of the second fin is matched with the support portion 11 of the first fin, and the abutment portion 21 of the second fin 2 located above is also abutted and matched with the upper side of the ear wall of the first fin ear 11 located below, so that the first fins 1 and the second fins 2 can have a stable structure after being alternately stacked.

[0043] It should be noted that, according to the above arrangement, the stacking process of the first fin 1 and the second fin 2 is also relatively convenient to operate, and the work efficiency is greatly improved. Moreover, this structure is a detachable structure, which is also convenient when the first fin 1 and the second fin 2 need to be disassembled.

[0044] Further, refer to Figure 3-4 As shown, a flange 13 extending upward is formed on the first side, and the hanging ear 11 is arranged on the flange 13 .

[0045] Such a configuration can ensure that the lug 11 also extends upward, thereby ensuring that the second fin 2 located between two adjacent first fins 1 and the abutment portion 21 of the second fin located above the adjacent first fin 1 can be more conveniently inserted into the lugs 11 of the two first fins.

[0046] Further preferably, the flange 13 is integrally formed with the first fin 1. Such a configuration is conducive to ensuring the firmness of the flange 13, and further ensuring the firmness of the lug 11 arranged on the flange 13.

[0047] Furthermore, a flow gap 3 is defined between any adjacent first fin 1 and any adjacent second fin 2. The flow gap 3 can accommodate coolant, which is beneficial for heat exchange between the fin and the coolant.

[0048] Furthermore, a plurality of spoiler structures 4 are arranged at intervals on the first fin 1 and the second fin 2, and the spoiler structure 4 includes a protrusion 41 protruding toward the flow gap 3. The arrangement of the protrusion 41 is conducive to increasing the contact area between the fin and the coolant on the one hand, and on the other hand, the protrusion 41 can guide the coolant to form turbulence. Compared with laminar flow, the tiny vortices inside the coolant in the turbulent state will greatly enhance the mixing and collision between fluid molecules, which helps to break the thermal boundary layer, reduce thermal resistance, and thus improve the heat transfer efficiency.

[0049] Furthermore, the first fin 1 and the second fin 2 have a first surface 14 and a first surface 22 facing the same direction, the first fin 1 has a second surface 15 facing away from the first surface 14 , and the second fin 2 has a second surface 23 facing away from the first surface 22 .

[0050] The spoiler structure 4 also includes a groove 42, and the protrusion 41 protrudes from the first surface 14 and the first surface 22 toward the flow gap 3 respectively. The groove 42 is arranged on the second surface 15 and the second surface 23. The groove 42 located on the second surface 15 is arranged at a position opposite to the protrusion 41 on the first surface 14; the groove 42 located on the second surface 23 is arranged at a position opposite to the protrusion 41 on the first surface 22.

[0051] With such arrangement, when the coolant flows through the circulation gap 2, it can be forced to generate vortex and secondary flow when passing through the plurality of grooves 42, forming a more complex three-dimensional flow pattern and increasing the turbulence of the fluid. The turbulence promotes the mixing of the coolant with the surfaces of the first fin 1 and the second fin, further accelerating the heat exchange.

[0052] Further preferably, the protrusion 41 and the groove 42 are both configured in a cylindrical shape, which is more conducive to improving the effects of the generated eddy current and secondary flow.

[0053] Furthermore, the height of the protrusion 41 protruding from the first surface of the fin toward the flow gap 3 is not higher than the thickness of the fin.

[0054] It should be noted that the fins include a first fin 1 and a second fin 2 .

[0055] Combination Figure 7As shown, the height h1 of the protrusion 41 protruding from the first surface 14 of the first fin toward the flow gap 3 is not higher than the thickness T1 of the first fin; the height h2 of the protrusion 41 protruding from the first surface 23 of the second fin toward the flow gap 3 is not higher than the thickness T2 of the second fin. Such a configuration is helpful for the stability of the protrusion 41.

[0056] When the fin is made of metal, and the height of the protrusion 41 is less than or equal to the thickness of the fin, optionally, the spoiler structure 4 is configured to be formed by stamping the fin.

[0057] Specifically, the protrusion 41 on the first fin 1 can be obtained by stamping, so the protrusion 41 on the first fin 1 is usually formed integrally with the first fin 1 .

[0058] Similarly, the protrusion 41 on the second fin 2 can also be obtained by stamping, so that the protrusion 41 on the second fin 2 is formed integrally with the second fin 2 .

[0059] The above-mentioned arrangement helps to ensure the stability of the protrusion 41 ; and can make the process of manufacturing the spoiler structure 4 simple, convenient and quick.

[0060] An embodiment of the utility model further provides a liquid cooling plate, which comprises a base plate and the fin assembly as described above, wherein the base plate has a receiving cavity for receiving cooling liquid, and the fin assembly is arranged in the receiving cavity.

[0061] In summary, the embodiments of the present invention achieve the following technical effects:

[0062] Through the above arrangement, the first fins 1 and the second fins 2 are stacked alternately, the ears 11 of the two adjacent first fins are nested and matched, and the abutment portion 21 of the second fin is matched with the support portion 11 of the first fin, and the abutment portion 21 of the second fin 2 located above is also abutted and matched with the upper side of the ear wall of the first fin ear 11 located below, so that the first fins 1 and the second fins 2 can have a stable structure after being alternately stacked.
