[0002] Heat sink fins are a device used to dissipate heat, usually installed on the surface of hardware such as electronic equipment or computers, to help the radiator dissipate heat more effectively and prevent the device from overheating. These heat sink fins are usually made of metal materials and have a large surface area, which can effectively increase the dissipation of heat. They usually have a strip or blade-shaped design, which can better contact with the air and speed up the transfer and dissipation of heat;

[0003] Increasing the number of strips or blades can certainly increase the heat dissipation surface area, but too many designs may cause the heat sink fins to be more susceptible to dust and debris, thus affecting the heat dissipation effect. In addition, a design that is too weak will also make the heat sink fins more susceptible to damage, reducing its durability and stability. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example

[0028] Reference Figures 1 to 5 , is an embodiment of the utility model, which provides a plate-type heat sink fin, such as Figure 1-Figure 2 As shown, the heat receiving assembly 100 includes a heat receiving plate 101, a mounting sleeve 104 is provided on the back of the heat receiving plate 101, and a heat receiving groove 105 and a heat receiving bump 106 are provided on the back of the heat receiving plate 101, which are in contact with the surface of the electronic component. The heat receiving groove 105 and the heat receiving bump 106 are more closely fitted to the electronic component, so as to heat the surface of the electronic component more evenly and facilitate sufficient heat dissipation.

[0029] The heat dissipation assembly 200 includes fins 201, which are arranged at equal distances on the surface of the heated plate 101. The heated plate 101 contacts the heat-generating electronic components to absorb heat, and the fins 201 exchange heat through the air, thereby achieving the purpose of cooling and dissipating the heat of the electronic components.

[0030] like Figure 2 As shown, the side of the heating plate 101 is provided with a side guard plate 102, and the bottom edge of the heating plate 101 is provided with a bottom guard plate 103. The addition of the guard plate can more effectively protect the fin 201 from the impact force from the side during use. Since the fin 201 is very thin, it is easy to deform over a large area under force;

[0031] like Figure 3As shown, the fins 201 are provided with spoiler grooves 201b at equal intervals, the spoiler grooves 201b on adjacent fins 201 are staggered, and a blade groove 201a is provided in the middle of the fin 201. When wind acts on the gap between the two fins 201 (it can be natural wind or fan-driven wind), the wind passes through between the two fins 201 and blows through the blade groove 201a of the fin 201 at the same time. The blade groove 201a serves to enhance the heat dissipation effect. The wind blows toward the spoiler groove 201b and enters the gap to form a spoiler, and at the same time enters the blade groove 201a to slow down the flow rate of the wind. Especially when natural wind blows, the purpose of increasing the heat dissipation time and optimizing the heat dissipation effect is achieved.

[0032] like Figure 3-Figure 4 As shown, the fin 201 is composed of a trunk 201-1 and a top spoiler block 201-2. Auxiliary heat dissipation recesses 201-1a are provided on both sides of the trunk 201-1 of the fin 201. The auxiliary heat dissipation recesses 201-1a can further increase the heat dissipation area of ​​the fin 201 and expand the volume of the heat dissipation chamber 201c. The top spoiler block 201-2 has a spoiler space 201-2a. The fin 201 and the heat receiving plate 101 are an integral structure. A heat dissipation chamber 201c is formed between adjacent fins 201. The top of the heat dissipation chamber 201c is a top heat dissipation outlet 201e. The cross-sectional shape of the heat dissipation chamber 201c is a trapezoid as a whole, and the shorter side of the trapezoid is the top heat dissipation outlet 201e.

[0033] Specifically, there are two situations. In the absence of wind, the fins 201 perform heat exchange with the air, and the hot air flow expands upward in the heat dissipation chamber 201c. Since the heat dissipation chamber 201c is trapezoidal, the air flow flows out from a narrower outlet, the flow rate increases, the heat energy is converted into kinetic energy, the temperature is reduced, and the external air is accelerated to enter the heat dissipation chamber 201c, thereby improving the heat dissipation efficiency of the fins 201. At the same time, the vortex formed in the spoiler groove 201b reduces the pressure, inhaling colder air, and further improving the heat dissipation efficiency.

[0034] When there is wind, air flows through the blade groove 201a, the spoiler groove 201b and the heat dissipation chamber 201c of the fin 201. The vortex in the spoiler groove 201b has a spoiler effect, which prolongs the wind action time and improves the heat dissipation efficiency. Generally speaking, in a limited space, it is not necessary to make the fin 201 too thin. It is only necessary to keep the structure stable within a certain thickness range to achieve a good heat dissipation effect.

[0035] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0036] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0037] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
