Description

Technical Field

[0001] This utility model relates to the field of electronic heat sink technology, specifically an integrated heat sink electronic heat sink. Background Technology

[0002] Electronic devices generate a lot of heat during operation. If the heat is not dissipated in time, it will lead to a decline in performance or even damage. Electronic heat sinks are devices that transfer heat from the components in electronic devices to the environment through heat conduction, convection and other methods.

[0003] Currently, electronic heat sinks on the market are mainly divided into three types according to their materials: aluminum, copper, and steel. Among them, aluminum heat sinks are the most widely used in electronic devices due to their light weight, good thermal conductivity, and moderate cost. To further improve the heat dissipation efficiency of aluminum heat sinks, a cooling fan is usually installed at the bottom, which is generally fixed to the aluminum heat sink by bolts.

[0004] However, while this bolt-fixed connection structure is sturdy and reliable, it has obvious drawbacks in daily maintenance and cleaning. When users need to clean the dust accumulated on the radiator, they need to separate the cooling fan from the aluminum-based radiator. This process usually requires the use of special tools to disassemble multiple bolt connection points. This disassembly and assembly method is not only cumbersome and time-consuming, but also easily leads to wear and damage to the bolts or threaded holes, reducing the service life of the equipment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Please refer to Figures 1 to 5 According to an embodiment of the present invention, a technical solution is provided: an integrated heat dissipation electronic heat sink, including a heat sink substrate 1 with heat dissipation fins 2 at the bottom; a wind shield 3 with a cooling fan 4 installed inside; and a locking mechanism for selectively fixing the wind shield 3 relative to the heat sink substrate 1 to restrict or allow the wind shield 3 to move relative to the heat sink substrate 1; the locking mechanism includes a locking part 5, a locking part 6, and a limiting ring 7; a limiting part 9 is provided at each end of the bottom of the heat dissipation fins 2, and a limiting groove 10 is provided on the wind shield 3 for the limiting part 9 to be inserted movably; the locking part 5 and the locking part 6 are also provided. Part 2 6 is rotatably mounted on the free ends of the two limiting parts 9 respectively; the limiting ring 7 movably passes through the locking part 1 5, and the top of the locking part 2 6 is provided with a clamping port 11 suitable for the movement of the limiting ring 7. The inner ring of the limiting ring 7 is provided with a locking ring 8, and the locking ring 8 and the limiting ring 7 are connected by a connecting part 12; the bottom of the wind shroud 3 is provided with an annular locking groove 14, the top of the locking ring 8 is provided with a locking block 15, and the bottom of the wind shroud 3 is provided with a locking inlet 16 communicating with the locking groove 14. The locking inlet 16 is suitable for the locking block 15 to move in and out, and the locking block 15 is suitable for sliding in the locking groove 14.

[0031] When a user needs to clean the heat sink substrate 1, the user first rotates the limiting ring 7 to move the locking block 15 out of the locking groove 14 through the locking inlet 16, thereby releasing the relative fixation between the air receiving cover 3 and the heat sink substrate 1. Then, the user lifts the heat sink substrate 1 off the air receiving cover 3 to drive the limiting part 9 out of the limiting groove 10. After the user removes the air receiving cover 3, the user can fully contact the heat sink substrate 1 and the heat dissipation fins 2 to remove accumulated dust or dirt. After cleaning, align the limiting part 9 with the limiting groove 10, insert the limiting part 9 into the limiting groove 10, then flip the locking part 5 to drive the limiting ring 7 to abut against the bottom of the air receiving cover 3. Then rotate the limiting ring 7 to allow the locking block 15 to enter the locking groove 14 through the locking inlet 16, so as to fix the air receiving cover 3 and the heat sink base plate 1 relative to each other again. The whole disassembly and assembly process is convenient and improves the efficiency of users disassembling and assembling the heat sink base plate 1 and the cooling fan 4.

[0032] In this embodiment, the locking groove 14 has an inverted T-shaped structure, and the locking block 15 has an inverted T-shaped structure. This arrangement can effectively prevent the locking block 15 from disengaging from the locking groove 14 when it slides within the locking groove 14. The upper part of the inverted T-shaped locking block 15 is wider and the lower part is narrower, which matches the shape of the locking groove 14. When the locking block 15 is inserted into the locking inlet 16 and slides into the locking groove 14, the upper part of the inverted T will be stuck in the inner track of the locking groove 14, so it will not easily disengage even when the equipment vibrates or is subjected to external force.

[0033] In this embodiment, the wind shield 3 and the locking block 15 are mutually attracted; this arrangement can provide additional fixing force after the locking block 15 has slid into the locking groove 14, preventing the locking block 15 from being accidentally loosened due to equipment vibration or external force.

[0034] In this embodiment, a plurality of friction-enhancing grooves 17 are spaced apart along the circumference of the limiting ring 7; this arrangement can increase the friction on the surface of the limiting ring 7, making it easier for the user to grip and operate the limiting ring 7, and making it less likely for the user's fingers to slip when rotating the limiting ring 7.

[0035] In this embodiment, the locking part 2 6 and the limiting ring 7 are mutually attracted; this arrangement is to prevent the locking part 2 6 from accidentally falling off or loosening during use.

[0036] In this embodiment, the locking part 2 6 is elastic, and the clamping opening 11 of the locking part 2 6 is tightened inward; this is configured to increase the clamping force of the locking part 2 6 on the limiting ring 7, thereby ensuring that the limiting ring 7 will not easily fall off during rotation.

[0037] In this embodiment, a set of fixing parts 18 are provided at relatively intervals at the free ends of the two limiting parts 9, and a shaft 19 is rotatably provided between the two fixing parts 18. The locking part 1 5 and the locking part 2 6 are respectively connected to the two shafts 19 through a connector 13. This arrangement is to achieve smooth rotation of the locking part 1 5 and the locking part 2 6.

[0038] In this embodiment, the shaft 19 and the limiting part 9 are detachably connected; this is designed so that when the user needs to repair or replace the limiting ring 7, there is no need to replace the entire heat sink assembly, thus saving maintenance costs.

[0039] In this embodiment, the bottom of the wind shield 3 is provided with a stabilizing groove 20 and a stabilizing groove 21, which are suitable for the locking part 5 and the locking part 6 to be movably embedded. With this configuration, the locking part 5 and the locking part 6 can be accurately embedded in the stabilizing groove 20 and the stabilizing groove 21, preventing the locking part 5 and the locking part 6 from shaking or shifting during use.

[0040] In this embodiment, stabilizing groove 1 20 and stabilizing groove 21 are respectively attracted to locking part 1 5 and locking part 2 6. With this configuration, when locking part 1 5 and locking part 2 6 are embedded in the corresponding stabilizing groove, the mutual attraction force can continuously provide additional fixing effect to prevent locking part 1 5 and locking part 2 6 from loosening or falling off.

[0041] Working principle: When the user needs to clean the heat sink base plate 1, firstly, rotate the limiting ring 7 to move the locking block 15 out of the locking groove 14 through the locking inlet 16, thereby releasing the relative fixation between the air receiver shroud 3 and the heat sink base plate 1. Then, lift the heat sink base plate 1 off the air receiver shroud 3 to drive the limiting part 9 out of the limiting groove 10. After the user removes the air receiver shroud 3, the heat sink base plate 1 and the heat dissipation fins 2 can be fully contacted to remove accumulated dust or stains. After cleaning, align the limiting part 9 with the limiting groove 10 so that the limiting part 9 is inserted into the limiting groove 10. Then, flip the locking part 5 to drive the limiting ring 7 to abut against the bottom of the air receiver shroud 3. Next, rotate the limiting ring 7 to allow the locking block 15 to enter the locking groove 14 through the locking inlet 16, thereby fixing the air receiver shroud 3 and the heat sink base plate 1 relative to each other again. The entire disassembly and assembly process is convenient and improves the efficiency of the user in disassembling and assembling the heat sink base plate 1 and the cooling fan 4.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
