Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to a heat sink assembly structure. Background Art

[0002] Heat sinks, or heat sinks for short, are classified as "passive heat sinks" in the field of electronic engineering design. They are made of metals that are light, easy to process, and have good thermal conductivity (mostly aluminum or copper, silver is too expensive and is generally not used) attached to the heating surface to dissipate heat in a composite heat exchange mode. Common heat sink fin materials include all-aluminum, all-copper, half-copper and half-aluminum, and copper foil.

[0003] Most of the existing combined heat sink fins are integrated structures. After long-term use, a large amount of dust easily accumulates on the surface of the heat sink fins and needs to be cleaned. However, due to the small gaps between the heat sink fins, it is very difficult to clean the dust, which has a certain impact on the heat dissipation effect. In order to improve it and solve the above problems, a heat sink assembly structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A heat sink assembly structure includes a heat sink base 1, heat sinks 2 and a mounting ring 3. The heat sink base 1 is provided with a mounting bracket 10 through a mounting mechanism, wherein multiple heat sinks 2 are sleeved on the outside of the mounting ring 3 through mounting holes 4, an upper top groove 12 is provided on the mounting ring 3, a positioning block 13 is provided in the upper top groove 12 through an upper top mechanism, a positioning hole 8 is provided on the heat sink 2 that is connected to the mounting hole 4 and corresponds to the positioning block 13, a disconnection port 5 is provided on the mounting ring 3, two movable grooves 6 are provided on the upper end surface of the heat sink 2 between the disconnection ports 5, and slide bars 14 are provided in the two movable grooves 6. A toggle plate 7 is slidably sleeved on the slide bar 14 through a dragging mechanism, and the toggle plate 7 is connected to the mounting ring 3 through a plug-in mechanism.

[0023] The mounting mechanism comprises a fixing screw 9 mounted on the heat dissipation base 1, and a mounting bracket 10 is threadedly sleeved on the outside of the fixing screw 9. The fixing screw 9 and the heat dissipation base 1 are connected by welding. The mounting bracket 10 is structured as shown in the figure.

[0024] The lifting mechanism includes a lifting spring arranged in the upper groove 12, and the two ends of the lifting spring are elastically connected to the outer wall of the positioning block 13 and the inner bottom wall of the upper groove 12 respectively. The lifting spring is a conventional component and is not drawn in the figure. It realizes the lifting operation of the positioning block 13 and can push the positioning block 13 into the positioning hole 8.

[0025] The dragging mechanism includes a dragging spring 15 which is sleeved on the outside of the sliding rod 14. The two ends of the dragging spring 15 are elastically connected to the outer wall of the toggle plate 7 and the inner wall of the movable groove 6 respectively. The dragging spring 15 realizes the dragging of the toggle plate 7, thereby realizing the dragging of the insertion rod 16, ensuring that the end of the insertion rod 16 can be inserted into the slot on the inner wall of the disconnection port 5.

[0026] The plug-in mechanism includes an insertion rod 16 installed on the toggle plate 7, the insertion rod 16 slides through the inner wall of the movable groove 6 and extends to the outside of the heat sink 2, and a slot corresponding to the insertion rod 16 is provided on the inner wall of the disconnection port 5. When the heat sink 2 in the disconnection port 5 is removed, the disconnection port 5 is exposed, and the remaining heat sinks 2 are easily disconnected from the mounting ring 3, thereby moving to the disconnection port 5 for disassembly.

[0027] Each heat sink 2 is provided with a connection groove 11 , and the plurality of heat sinks 2 are circumferentially distributed with equal intervals, and the mounting bracket 10 is located in the connection groove 11 , thereby achieving support and positioning of components such as the heat sink 2 and the mounting ring 3 .

[0028] When the utility model is used, Figure 1In the shown state, the heat sink 2 plays a role in heat dissipation. When it is necessary to clean the dust adhered to the surface of the heat sink 2 or to maintain and replace the heat sink 2, first, toggle the toggle plate 7 in the movable groove 6, and the toggle plate 7 moves on the slide bar 14 and stretches the drag spring 15. Then the toggle plate 7 drives the plug 16 to move and disengage from the slot on the inner wall of the disconnection port 5. Then the heat sink 2 is disassembled to make the disconnection port 5 leak out. At this time, when the remaining heat sinks 2 are disassembled, it is necessary to press the positioning block 13 in the positioning hole 8. The positioning block 13 presses down the top spring and enters the top groove 12 and disengages from the positioning hole 8. Then slide the heat sink 2 to the disconnection port 5, move the heat sink 2, and disengage the mounting bracket 10 from the connecting groove 11.

[0029] In this solution, the heat sink 2 can be flexibly disassembled and assembled for easy maintenance, replacement and cleaning, and the installation amount of the heat sink 2 can be reduced according to actual conditions, which has high convenience and flexibility in use.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
