Abstract
Description
Technical Field
[0001] This utility model relates to the field of finned heat sink technology, specifically a high-efficiency heat dissipation finned heat sink. Background Technology
[0002] With the rapid development of information technology, high-performance computing devices, servers, and other electronic devices are playing an increasingly important role in modern society. However, these devices generate a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it will lead to a decline in device performance, reduced stability, or even damage. Therefore, heat dissipation technology has become a crucial aspect of electronic device design.
[0003] Currently, finned heat sinks are an existing heat dissipation technology, comprising a heat-conducting base and multiple sets of metal fins fixed side-by-side on the base. The heat-conducting base is typically located on and tightly connected to the heat source in electronic equipment. Heat is transferred through the base to the individual metal fins of the finned heat sink via thermal conduction. A cooling fan located on one side of the finned heat sink then delivers airflow to the finned heat sink. The airflow passes through the tiny gaps between the metal fins, carrying away the heat accumulated on the fins and dissipating it into the surrounding environment, thus achieving a heat dissipation effect. However, most of the heat dissipation channels in existing finned heat sinks are straight, resulting in a limited contact area between the heat sink fins and the airflow. This leads to low heat exchange efficiency between the heat sink fins and the airflow, reducing the overall heat dissipation effect of the finned heat sink.
[0004] Therefore, there is an urgent need for a high-efficiency finned heatsink to solve the above problems. Utility Model Content
[0005] Based on the above, the purpose of this utility model is to provide a high-efficiency heat dissipation finned radiator to solve the problem that the contact area between the heat dissipation fins and the airflow is limited in existing finned radiators, which reduces the heat dissipation effect of the finned radiator.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A high-efficiency heat dissipation finned radiator includes a heat-conducting base, a heat dissipation structure, and a protruding structure. The heat dissipation structure includes multiple sets of heat dissipation fins. The multiple sets of heat dissipation fins are evenly distributed on the heat-conducting base. Each heat dissipation fin includes a fin body, a first side surface, and a second side surface. The fin body is disposed on the heat-conducting base. The first side surface is located on one side of the fin body, and the second side surface is located on the other side of the fin body. The first side surface and the second side surface are arranged opposite to each other. The protruding structure is disposed on the first side surface or on the first side surface and the second side surface. The protruding structure includes multiple sets of bumps for increasing the contact area. The multiple sets of bumps are regularly or irregularly distributed on the first side surface or on the first side surface and the second side surface.

[0012] As a preferred embodiment of a high-efficiency heat dissipation finned heat sink, the protrusions on the first side and the protrusions on the second side are staggered along the Y-axis direction.
[0013] As a preferred embodiment of a high-efficiency heat dissipation finned heat sink, the protrusion is hemispherical, and a first heat dissipation channel is formed between two adjacent sets of heat dissipation fins and the protrusion.
[0014] As a preferred embodiment of a high-efficiency heat dissipation finned heat sink, the protrusion has a cylindrical structure, and a second heat dissipation channel is formed between two adjacent sets of heat dissipation fins and the protrusion.
[0015] As a preferred embodiment of a high-efficiency heat dissipation finned heat sink, the heat dissipation fins include a first fin and a second fin, both of which are disposed on the heat-conducting base; the first fin and the second fin are respectively provided with outwardly extending connecting portions at both ends; the length of the first fin is less than the length of the second fin.
[0016] As a preferred embodiment of a high-efficiency heat dissipation finned heat sink, the heat-conducting base is provided with four sets of circumferentially distributed connection holes.
[0017] The beneficial effects of this utility model are as follows:
[0018] By setting up a raised structure with multiple sets of regularly or irregularly distributed bumps, the contact area between the heat dissipation fins and the airflow is increased, improving the overall heat dissipation performance of the finned heat sink. At the same time, the arrangement of multiple sets of bumps creates complex and varied heat dissipation channels between adjacent sets of heat dissipation fins, extending the contact time between the airflow and the heat dissipation fins, further improving the heat exchange efficiency between the airflow and the heat dissipation fins, and thus further improving the heat dissipation efficiency of the finned heat sink.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.
[0032] In one embodiment of this utility model, such as Figure 1-6As shown, a high-efficiency heat dissipation finned heat sink is provided, comprising a heat-conducting base 10, a heat dissipation structure, and a protruding structure. The heat dissipation structure includes multiple sets of heat dissipation fins 20. These multiple sets of heat dissipation fins 20 are evenly distributed on the heat-conducting base 10. Each heat dissipation fin 20 includes a fin body 201, a first side surface 21, and a second side surface 22. The fin body 201 is disposed on the heat-conducting base 10. The first side surface 21 is located on one side of the fin body 201, and the second side surface 22 is located on the other side of the fin body 201. The first side surface 21 and the second side surface 22 are arranged opposite to each other. The protruding structure is disposed on the first side surface 21 or on the first side surface 21 and the second side surface 22. The protruding structure includes multiple sets of protrusions 30 for increasing the contact area. These multiple sets of protrusions 30 are regularly or irregularly distributed on the first side surface 21 or on the first side surface 21 and the second side surface 22.
[0033] By setting up a raised structure with multiple sets of regularly or irregularly distributed protrusions 30, the contact area between the heat dissipation fins 20 and the airflow is increased, thereby improving the overall heat dissipation performance of the finned heat sink. At the same time, the arrangement of multiple sets of protrusions 30 creates complex and varied heat dissipation channels between adjacent sets of heat dissipation fins 20, extending the contact time between the airflow and the heat dissipation fins 20, further improving the heat exchange efficiency between the airflow and the heat dissipation fins 20, and thus further improving the heat dissipation efficiency of the finned heat sink.
[0034] Preferably, multiple sets of protrusions 30 are evenly distributed along the X-axis on the first side surface 21. Multiple sets of protrusions 30 are also staggered along the Y-axis on the first side surface 21. This arrangement of equal-spaced protrusions 30 along the X-axis and staggered along the Y-axis creates multiple vertically interlaced heat dissipation channels on the first side surface 21, extending the contact time between the airflow and the heat dissipation fins 20 and improving the heat exchange efficiency between them.
[0035] Preferably, multiple sets of protrusions 30 are evenly distributed on the first side surface 21 along the X-axis. Multiple sets of protrusions 30 are also evenly distributed on the first side surface 21 along the Y-axis. This even distribution of the protrusions 30 along the X and Y axes creates multiple parallel heat dissipation channels on the first side surface 21, extending the contact time between the airflow and the heat dissipation fins 20 and improving the heat exchange efficiency between them.
[0036] Preferably, multiple sets of protrusions 30 are respectively disposed on the first side 21 and the second side 22. The multiple sets of protrusions 30 are regularly or irregularly distributed on the first side 21 and the second side 22. By providing protrusions 30 on both the first side 21 and the second side 22, the heat dissipation area and heat dissipation channels on the heat dissipation fins 20 are further increased, thereby improving the heat dissipation efficiency of the finned heat sink.
[0037] Furthermore, the protrusions 30 on the first side 21 and the second side 22 are flush along the Y-axis. The flush arrangement of the protrusions 30 on the first side 21 and the second side 22 creates multiple sets of parallel heat dissipation channels between adjacent sets of heat dissipation fins 20. Since heat dissipation channels are formed on both the first side 21 and the second side 22, the contact time between the airflow and the heat dissipation fins 20 is extended, further improving the heat exchange efficiency between the airflow and the heat dissipation fins 20.
[0038] Furthermore, the protrusions 30 on the first side 21 and the protrusions 30 on the second side 22 are staggered along the Y-axis. The staggered arrangement of the protrusions 30 on the first side 21 and the second side 22 creates multiple vertically staggered heat dissipation channels between adjacent sets of heat dissipation fins 20, and heat dissipation channels are formed on both the first side 21 and the second side 22, extending the contact time between the airflow and the heat dissipation fins 20 and further improving the heat exchange efficiency between the airflow and the heat dissipation fins 20.
[0039] Preferably, the protrusion 30 is hemispherical, and a first heat dissipation channel is formed between two adjacent sets of heat dissipation fins and the protrusion 30. By setting the hemispherical protrusion 30, the contact area between the airflow and the heat dissipation fins 20 is increased, the heat exchange efficiency between the airflow and the heat dissipation fins 20 is improved, and thus the heat dissipation efficiency of the finned heat sink is improved.
[0040] Preferably, the protrusion 30 is a cylindrical structure, and a second heat dissipation channel is formed between two adjacent sets of heat dissipation fins and the protrusion 30. By setting the cylindrical protrusion 30, the contact area between the airflow and the heat dissipation fins 20 is increased, the heat exchange efficiency between the airflow and the heat dissipation fins 20 is improved, and thus the heat dissipation efficiency of the finned heat sink is improved.
[0041] Preferably, the heat dissipation fins 20 include a first fin 23 and a second fin 24, both of which are disposed on the heat-conducting base 10. Each end of the first fin 23 and the second fin 24 has an outwardly extending connecting portion 25. The length of the first fin 23 is shorter than the length of the second fin 24. By providing first fins 23 and second fins 24 of different lengths, the finned heat sink can be lengthened according to the heat dissipation conditions of the heat source in different locations, reducing the production cost of the finned heat sink.
[0042] Furthermore, the heat-conducting base 10 is provided with four sets of circumferentially distributed connection holes 11. By providing connection holes 11, it is convenient to connect and fix the heat sink to other components.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
