Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation devices, and specifically relates to a heat sink. Background Technology

[0002] As a key component of a cooling system, the radiator typically consists of an inlet, an outlet, cooling fins, and a radiator core. During operation, coolant flows inside the radiator, while air passes through the outside of the radiator core to achieve efficient heat transfer and exchange. It is widely used in various fields, including vehicles and home appliances.

[0003] Existing radiators are often designed with a universal symmetrical shape for ease of manufacturing and molding. While this makes them easy to process, it is not conducive to installation in specific environments and has a narrow range of applications. Furthermore, the symmetrical structure can also lead to inconvenience in handling and placement, reducing work efficiency.

[0004] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] [First Embodiment] like Figure 1-4 The image shows a heat sink provided in the first embodiment of this utility model, including a base 100, as shown. Figure 1-2 As shown, a sliding portion 101 extends downward from the bottom of the base 100. A groove 1011 is formed on the inner wall of the sliding portion 101. The groove 1011 slides into the installation environment, facilitating the adjustment of the radiator's position in the installation environment as needed. A front groove 102 and a rear groove 103 are respectively formed on the top sides of the base 100. A front mounting hole 1021 is formed inside the front groove 102, and a rear mounting hole 1031 is formed inside the rear groove 103. A fastener passes through the front mounting hole 1021 and the rear mounting hole 1031 to fix the radiator in the installation environment. As a further preferred embodiment, the width of the front groove 102 is smaller than the width of the rear groove 103, and the diameter of the front mounting hole 1021 is larger than the diameter of the rear mounting hole 1031.

[0025] Several heat dissipation fins 200 are fixedly installed on the top of the base 100. Upper positioning parts are provided on the top of both sides of the heat dissipation fins 200, and lower positioning parts are provided on the bottom of both sides of the heat dissipation fins 200. The upper positioning parts are symmetrically arranged on both sides of the heat dissipation fins 200, while the lower positioning parts are asymmetrically arranged on both sides. By symmetrically arranging the upper positioning parts on both sides of the heat dissipation fins and asymmetrically arranging the lower positioning parts, the symmetrical arrangement of the upper positioning parts facilitates overall molding and ensures an aesthetically pleasing appearance, while the asymmetrical arrangement of the lower positioning parts meets installation requirements in specific environments, effectively increasing the applicability. Furthermore, the asymmetrical arrangement of the lower positioning parts on both sides of the heat dissipation fins allows for direct visual observation by the user, facilitating placement and removal and improving loading and unloading efficiency. Figure 4 As shown, in this embodiment, several heat dissipation fins 200 are arranged at varying heights on the top of the base 100. Sliding claws 201 are provided on the top of the front and rear heat dissipation fins 200. These claws, through the bottom sliding groove 1011 and the top sliding claw 201, allow for sliding engagement with the installation environment, enabling on-demand adjustment of the heat sink's position within the installation environment. The sliding connection on both sides also improves the stability of the sliding process. Furthermore, a positioning platform 202 is provided on the top of the front sliding claw 201. This positioning platform 202 facilitates positioning and engagement, and also helps users identify the front-to-back direction of the heat sink when placing or removing it.

[0026] like Figure 1-2 As shown, in this embodiment, the upper positioning part includes upper positioning grooves 205 formed on the top of both sides of the heat dissipation fins 200. The cross-section of the upper positioning grooves 205 is square and the number of grooves on both sides of the heat dissipation fins 200 is equal. The lower positioning part includes lower left positioning grooves 203 and lower right positioning grooves 204 formed on the bottom of both sides of the heat dissipation fins 200. The cross-section of the lower left positioning grooves 203 and lower right positioning grooves 204 is square and the number of grooves on both sides of the heat dissipation fins 200 is unequal. In this embodiment, the number of lower left positioning grooves 203 is less than the number of lower right positioning grooves 204. By symmetrically arranging the upper positioning part on both sides of the heat dissipation fins and asymmetrically arranging the lower positioning part on both sides of the heat dissipation fins, the symmetrical arrangement of the upper positioning part facilitates overall forming and ensures an aesthetically pleasing appearance, while the asymmetrical arrangement of the lower positioning part meets the installation requirements in specific environments, effectively increasing the applicability. Furthermore, by asymmetrically arranging the lower positioning part on both sides of the heat dissipation fins, it is easier for users to visually observe and thus facilitates placement and removal, improving loading and unloading efficiency.
