Description

Technical Field

[0001] This utility model relates to the field of finned heat sinks, and in particular to a finned heat sink that can be quickly disassembled and assembled. Background Technology

[0002] Finned heatsinks, also known as finned radiators, are a common type of heat exchange device widely used in many fields, including computer CPU cooling, industrial equipment cooling, and greenhouse heating in horticulture. The working mechanism of a finned heatsink is primarily based on the principles of thermal radiation and air convection. This device effectively increases the contact area with the air through the orderly arrangement of metal fins, enabling heat transfer from the heat source (such as the CPU) to the heatsink, and then dissipating the heat to the surrounding environment through the contact between the fins and the air. Heat pipes play a role in heat conduction within the heatsink, transferring heat from the base (chip) to the fins, while the fins primarily perform the heat dissipation function. A finned heatsink typically consists of core components such as heatsink fins, heat pipes, and a base. The heatsink fins are generally made of copper or aluminum, both widely chosen due to their excellent thermal conductivity. The heat pipes are responsible for transferring heat from the base to the heatsink. The base, which contacts the heat source such as the CPU, is typically made of copper or nickel-plated copper to improve heat conduction efficiency.

[0003] In current applications, finned heatsinks have various installation methods. The need for numerous bolts for fixing not only increases the time and difficulty of disassembly and installation, but also raises the overall cost due to the use of bolts and other fasteners. Therefore, ensuring the flatness and sufficient strength of the mounting surface to withstand the weight of the heatsink and the tightening force are factors that must be considered in practical applications. Utility Model Content

[0004] The main objective of this invention is to provide a finned heat sink that can be quickly disassembled and assembled, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-release finned heat sink includes a heat sink fin body, a snap-fit ​​assembly, and a cooling fan. The snap-fit ​​assembly is installed on both sides of the upper end of the heat sink fin body, and the cooling fan is installed on the heat sink fin body through the snap-fit ​​assembly. The heat dissipation fins are provided with mounting protrusions at the three corners at the lower end, and each mounting protrusion has a mounting hole. The lower end of the heat sink fin body is provided with a quick-install mounting base. The quick-install mounting base includes a base body, a connector, and a blocking strip. The base body is located at the lower end of the heat sink fin body, and the upper end of the base body has a placement groove. The lower end of the placement groove has a through groove, and the inner wall of the placement groove has an insertion port adapted to the mounting protrusion. The opening of the placement groove of the base body is connected to the blocking strip through the connector, and the side wall of the blocking strip has a mating notch adapted to the mounting protrusion. The mating notch has a mating hole.

[0006] As a preferred embodiment of this application, the base is designed in a square shape, and the edges of the base and the blocking strip are designed in an arc shape. The placement slot is adapted to the heat dissipation fin body, and the heat dissipation fin body and the mounting protrusion are designed as an integral part. The edges of the mounting protrusion are designed in an arc shape. As a preferred embodiment of this application, the three mounting protrusions are respectively located in the three corners of the heat sink fin body, wherein two mounting protrusions are symmetrically arranged and inserted into the socket, and an anti-slip pad is provided between the socket and the mounting protrusion connected to it. As a preferred embodiment of this application, the connector includes a connecting sleeve and a limiting bolt. The connecting sleeve is placed in the circular hole of the blocking strip and the seat. The two ends of the connecting sleeve are connected to the limiting bolts. The bolt heads of the limiting bolts are placed in the circular hole of the blocking strip and the seat, thereby realizing the limiting connection of the blocking strip and the seat. As a preferred embodiment of this application, the mating notch is U-shaped, the width of the mating notch is twice that of the mounting protrusion, and the edge of the mating notch is arc-shaped. As a preferred embodiment of this application, the placement slot and the through slot are designed with stepped holes. The through slot is a connection notch at the bottom of the heat dissipation fin body, used for connecting the heat dissipation fin body and the device to be cooled.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The mounting protrusion at the lower end of the heatsink fins and the quick-release mounting bracket enhance the stability of the heatsink fins and provide diverse installation options. The matching design of the mounting protrusion and the connector, along with the anti-slip pads, effectively prevents slippage and further improves the structural stability.

[0008] The quick-release mounting bracket design makes the installation and removal of the heat sink fins simple and fast. With a few simple operations, the heat sink fins can be connected and disconnected from the device being cooled, which not only improves work efficiency but also makes it easier for users to clean and maintain the heat sink.

[0009] The integrated design of the heat dissipation fins and mounting protrusions, along with the curved design of the base and blocking strip, not only enhances the overall aesthetics of the heatsink but also makes the connection smoother and improves the user experience.

[0010] The heatsink's high efficiency is attributed to its ingenious design. The heatsink fins connect to the device being cooled via slots, ensuring effective heat transfer. Simultaneously, the powerful airflow from the cooling fan further accelerates heat dissipation, thus enhancing cooling efficiency. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 4 As shown, a quick-installation finned heatsink mainly consists of heatsink fins 2, snap-fit ​​components 5, and a cooling fan 6. The snap-fit ​​components 5 are installed on both sides of the upper end of the heatsink fins 2, allowing the cooling fan 6 to be easily and quickly installed on the heatsink fins 2 via the snap-fit ​​components 5.

[0015] Specifically, mounting protrusions 3 are designed at the three lower corners of the heat sink fin body 2, and each individual mounting protrusion 3 has a mounting hole 4. This design not only enhances the stability of the heat sink fin body 2, but also provides more installation possibilities.

[0016] In addition, a quick-install mounting base 1 is provided at the lower end of the heat sink fin body 2. The mounting base includes a base body 11, a connector 15, and a blocking strip 16. The base body 11 is located at the lower end of the heat sink fin body 2, with a placement groove 12 at its upper end and a through groove 13 at its lower end. The inner wall of the placement groove 12 is also designed with an insertion port 14 that matches the mounting protrusion 3, and the blocking strip 16 is connected to the opening of the placement groove 12 of the base body 11 through the connector 15. The side wall of the blocking strip 16 has a mating notch 17 that matches the mounting protrusion 3, and a mating hole 18 is also provided on the mating notch 17.

[0017] To further enhance the structural stability and aesthetics, the base 11 is square-shaped, with rounded edges on both its sides and the edges of the blocking strip 16. The mounting slot 12 is fitted to the heat dissipation fin body 2, ensuring overall compactness and stability. The heat dissipation fin body 2 and the mounting protrusion 3 are integrated into a single design, with the edges of the mounting protrusion 3 also rounded, resulting in a smoother overall appearance.

[0018] Three mounting protrusions 3 are located at the three corners of the heat sink fin body 2, with two of the mounting protrusions 3 being symmetrically arranged and inserted into the socket 14. To prevent slippage, an anti-slip pad is also provided between the socket 14 and the mounting protrusion 3 it is connected to.

[0019] The design of the connector 15 is also quite sophisticated, including a connecting sleeve and a limiting bolt. The connecting sleeve is placed in the round holes of the blocking strip 16 and the seat 11, and the two ends of the connecting sleeve are connected to the limiting bolts. The bolt heads of the limiting bolts are placed in the round holes of the blocking strip 16 and the seat 11, thereby achieving a limiting connection between the blocking strip 16 and the seat 11 and ensuring the stability of the overall structure.

[0020] The docking notch 17 is U-shaped, with a width twice that of the mounting protrusion 3, and its edges are also curved to make docking smoother. The placement slot 12 and the through slot 13 adopt a stepped hole design. The through slot 13 serves as a connection notch at the bottom of the heat dissipation fin body 2, used to connect the heat dissipation fin body 2 to the device to be cooled, ensuring the efficient heat dissipation performance of the heat sink.

[0021] Align the mounting protrusion 3 of the heat sink fin body 2 with the insertion port 14 of the quick-release mounting base 1 and insert it. Attach the cooling fan 6 to both sides of the upper end of the heat sink fin body 2 using the snap-fit ​​assembly 5, ensuring a secure connection. Connect the blocking strip 16 at the opening of the placement slot 12 of the base 11 using the connector 15. Place the connecting sleeve in the round holes of the blocking strip 16 and the base 11, with limit bolts connected to both ends. Place the bolt heads of the limit bolts in the round holes of the blocking strip 16 and the base 11 to achieve a limiting connection between the blocking strip 16 and the base 11. Check that the installation is secure to ensure the heat sink functions properly.

[0022] First, remove the cooling fan 6. By reversing the operation of the snap-fit ​​assembly 5, remove the cooling fan 6 from the heat sink fin body 2. Remove the connector 15, take the limiting bolt out of the round hole in the stop bar 16 and the base 11, and separate the connecting sleeve. Pull the mounting protrusion 3 of the heat sink fin body 2 out of the insertion port 14 of the base 11 to complete the disassembly. Check whether the disassembled parts are intact for future use.
