Description

Technical Field

[0001] This utility model relates to the technical field of computer heat sinks, specifically a self-dust-removing air-cooled computer heat sink. Background Technology

[0002] Air-cooled heatsinks remain the mainstream cooling solution for personal computers, servers, and other electronic devices due to their simple structure, low cost, and high reliability. Their core principle is to increase the contact area with air through heatsink fins, and then use a fan to force convection, quickly removing heat generated by components such as the central processing unit.

[0003] However, existing air-cooled heatsinks exhibit a significant drawback during long-term use: dust removal and maintenance are extremely inconvenient. To ensure heat dissipation efficiency, the cooling fan needs to continuously draw in a large amount of air from the environment, and dust, lint, and other impurities in the air accumulate in the gaps between the heatsink fins. As dust accumulates, it forms a heat insulation layer, severely hindering the heat exchange efficiency of the fins, leading to increased processor temperature, decreased performance, and even triggering system protection and automatic shutdown due to overheating, affecting the stable operation and lifespan of the equipment. Furthermore, existing multi-functional heatsinks have complex installation structures and cumbersome disassembly processes, requiring improvement. Therefore, those skilled in the art have proposed a self-cleaning air-cooled computer heatsink to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning air-cooled computer heat sink to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-cleaning air-cooled computer heatsink includes a base plate with mounting holes at its corners and mounting posts installed in these holes. A circular hole is located in the center of the base plate, and a bracket is connected within this hole. A heat dissipation filter assembly is mounted on the bracket. A fan assembly is detachably mounted on the top of the heat dissipation filter assembly, and a wiring assembly is mounted on the top of the fan assembly. The heat dissipation filter assembly includes a filter cylinder, a heat dissipation fin assembly mounted on the outer wall of the filter cylinder, and a dust removal component mounted inside the filter cylinder. A circular ring plate is connected to the top of the filter cylinder. The heat dissipation fin assembly is cylindrical, and the outer diameter of the circular ring plate matches the outer diameter of the heat dissipation fin assembly, while the inner diameter of the circular ring plate matches the inner diameter of the filter cylinder.

[0007] As a further improvement of this utility model: the inner diameter of the circular hole is consistent with the outer diameter of the heat dissipation fin assembly, the bracket is cross-shaped, and the bottom end of the filter cylinder is bonded to the center of the bracket.

[0008] As a further embodiment of this utility model: the fan assembly includes a frame and a fan body installed in the center of the frame. The bottom two sides of the frame are elastically connected with buckle plates. The two sides of the heat dissipation fin assembly are provided with buckle grooves that cooperate with the buckle plates. The outer wall of the buckle plate is provided with a toggle plate.

[0009] As a further embodiment of this utility model: the circuit assembly includes a wire and a wiring module connected to one end of the wire, the other end of the wire is connected to the fan body, and a cable management rack is provided on the top of the frame.

[0010] As a further embodiment of this utility model: the dust removal component is composed of several filter sheets distributed at equal intervals, and the filter sheets are sintered from multiple layers of metal mesh.

[0011] This invention offers the following advantages: By integrating the heat dissipation fins and filter cylinder into a cylindrical heat dissipation and filtration assembly, and embedding a dust removal component inside, while employing a quickly detachable fan assembly at the top, it achieves integrated heat dissipation and dust removal functions. When dust removal maintenance is required, users only need to easily remove the top fan assembly to directly expose and access the entire filter cylinder and internal dust removal structure, completely avoiding the difficulties of traditional solutions that require tools and cumbersome disassembly of the entire fan and fin assembly. This greatly simplifies the operation process and lowers the maintenance threshold and risk. Secondly, the unique cylindrical airflow design forces the intake air to flow sequentially through the heat dissipation fins for efficient heat exchange, and then through the internal dust removal component for filtration. This process not only ensures excellent heat dissipation performance but also automatically traps and collects dust during airflow, effectively preventing dust accumulation between the heat dissipation fins. This maintains long-term stable heat dissipation performance from the source, significantly improving the long-term operational reliability of the equipment and the user experience.

[0021] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0022] Example 1: Please refer to Figures 1 to 4 Please see Figures 1 to 4A self-cleaning air-cooled computer heatsink includes a base plate 1. A mounting hole 102 is provided at the corner of the base plate 1. A mounting post 5 is installed in the mounting hole 102 via a threaded connection or interference fit. A circular hole 101 is provided in the center of the base plate 1. A bracket 103 is connected to the circular hole 101 via a snap-fit ​​or screw. A heat dissipation filter assembly 2 is installed on the bracket 103. A fan assembly 3 is detachably installed on the top of the heat dissipation filter assembly 2 via a quick-release structure. A wiring assembly 4 is installed on the top of the fan assembly 3. The heat dissipation filter assembly 2 includes a filter cylinder 201, a heat dissipation fin assembly 203 installed on the outer wall of the filter cylinder 201 by welding or press fitting, and a dust removal assembly 202 installed inside the filter cylinder 201 via a slot or snap-fit ​​structure. The top of the filter cylinder 201 is connected to a circular ring plate 204 by welding or threading. The heat dissipation fin assembly 203 is cylindrical. The outer diameter of the circular ring plate 204 is the same as the outer diameter of the heat dissipation fin assembly 203, and the inner diameter of the circular ring plate 204 is the same as the inner diameter of the filter cylinder 201. The circular ring plate 204 seals the top of the heat dissipation fin assembly 203, forming a directional air duct. This ensures that the air passing through the heat dissipation fin assembly 203 must be filtered by the dust removal component 202 before being discharged from the center of the circular ring plate 204, thus achieving both heat dissipation and dust removal functions.

[0023] Please see Figure 1 , Figure 3 , Figure 4 The inner diameter of the circular hole 101 is consistent with the outer diameter of the heat dissipation fin assembly 203, ensuring that the bottom of the heat dissipation fin assembly 203 is in close contact with the base plate 1 to optimize heat conduction. The bracket 103 is cross-shaped, and its arm is fixed to the inner wall of the circular hole 101 by screws. The central platform is connected to the bottom end of the filter cylinder 201 by thermally conductive adhesive or welding, providing stable support and assisting in heat conduction.

[0024] Please see Figure 1 , Figure 2 The fan assembly 3 includes a frame 301 and a fan body 304 mounted on the center of the frame 301 by screws. The bottom ends of the frame 301 are elastically connected to clip plates 302 via springs or elastic plastic sheets. The heat dissipation fin assembly 203 has slots 205 on both sides that mate with the clip plates 302. The outer wall of the clip plates 302 has an easily operable actuating plate 303. By pressing or actuating the actuating plate 303, the clip plates 302 can be engaged or disengaged from the slots 205, enabling quick installation and disassembly of the fan assembly 3.

[0025] Example 2: See Figure 1 , Figure 2Based on Embodiment 1, the wiring assembly 4 includes a conductor 401 and a standard 4-pin or 3-pin wiring module 402 connected to one end of the conductor 401. The other end of the conductor 401 is connected to the fan body 304. A cable management rack 305 is integrally provided on the top of the frame 301 to fix and guide the direction of the conductor 401 and keep the interior tidy.

[0026] The dust removal component 202 consists of several equally spaced filter sheets, which are made of multiple layers of stainless steel or aluminum alloy metal mesh sintered together, and have good permeability, mechanical strength and re-cleanability.

[0027] Working Principle: When the heatsink is powered on, the fan assembly 3 starts, generating an axial airflow from top to bottom. Air is first drawn in and flows through the cylindrical heatsink fins 203. The heatsink fins 203 are in close contact with the CPU base plate 1, conducting heat rapidly to the large heat dissipation surface area. The forced convection airflow efficiently exchanges heat with the heatsink fins 203, carrying away a large amount of heat. Subsequently, this pre-heated air is pushed into the filter cylinder 201. The air entering the filter cylinder 201 must pass through the dust removal assembly 202 installed inside. The dust removal assembly 202 consists of multiple layers of sintered metal mesh filters, effectively intercepting dust particles, lint, and other impurities carried in the airflow. The clean air is finally exhausted from the system by the fan through the central opening of the top annular plate 204. This "heat dissipation first, filtration later" directional airflow design ensures that the heat dissipation fin assembly 203 is always in a relatively clean environment, preventing dust from accumulating in the gaps between the heat dissipation fins and forming an insulation layer, thus maintaining long-term stable heat dissipation performance. When cleaning is required, the user simply needs to use their fingers to move the lever plates 303 on both sides of the fan assembly 3 frame 301 to overcome the elastic force, causing the latch plate 302 to disengage from the slot 205 on the heat dissipation fin assembly 203, allowing the entire fan assembly 3 along with the wiring assembly 4 to be removed upwards. This instantly exposes the filter cylinder 201 and its internal dust removal assembly 202. The user can directly clean the accumulated dust on the dust removal assembly 202, and can remove it for washing or replacement.

Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
