Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, and specifically relates to a heat sink structure that can be cleaned. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance, and is mostly made of aluminum alloy, brass or bronze. Its shape can be plate-shaped, sheet-shaped or multi-sheet-shaped, etc. In electronic devices such as computers, mobile phones, tablets and laptops, heat sinks play an important role in helping to reduce the device temperature, thereby extending the service life. The working principle of the heat sink is based on the physical principles of heat conduction and heat dissipation. When an electronic component generates heat, the heat sink conducts the heat from the component to itself by contacting it, and then dissipates the heat to the surrounding environment through its own surface area. In order to conduct heat more effectively, a layer of thermal grease is usually applied to the contact surface between the electronic component and the heat sink to reduce the thermal resistance and improve the heat dissipation efficiency.

[0003] However, due to the relatively compact structure of the heat sink and its fixed and uniform arrangement, when the heat sink is used for a long time, its surface will be contaminated with dust, which affects the heat dissipation effect. At the same time, it is difficult to effectively clean the dust on the heat sink, thus affecting the service life of the heat sink.

[0004] Therefore, a heat sink structure that can be cleaned is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment:

[0031] Please refer to Figures 1-6 , this embodiment provides a cleanable heat sink structure, including a U-shaped frame 1. Two positioning grooves 11 are symmetrically opened on both side faces of the U-shaped frame 1. A storage groove 14 is opened at the bottom of the inner side face of the positioning groove 11. A clamping block 5 is installed inside the storage groove 14. On both side faces of the U-shaped frame 1 between the two positioning grooves 11, a sliding groove 12 is opened. At both ends inside the sliding groove 12, a dial plate 6 is symmetrically installed. One end of the dial plate 6 is connected to a sliding rod 7. One end of the sliding rod 7 is fixedly connected to the clamping block 5. A second spring 8 is sleeved and installed on the outer ring surface of the sliding rod 7;

[0032] Between the two ends at the top of the U-shaped frame 1, two arched frames 3 are clamped. At the bottom of both side faces at both ends of the arched frame 3, a docking groove 32 is opened. The docking groove 32 and the clamping block 5 are in a clamped state. Both ends of the arched frame 3 are slidably installed inside the positioning groove 11;

[0033] On the inner bottom of the U-shaped frame 1 in the length direction, a plurality of card slots 13 are equidistantly opened. A plurality of heat sinks 2 are evenly installed in the length direction inside the U-shaped frame 1. The bottoms of the heat sinks 2 are inserted inside the card slots 13. At both ends of the top of each heat sink 2, a clamping groove 21 is symmetrically opened. The arched frame 3 is clamped inside the clamping grooves 21 at the tops of the plurality of heat sinks 2. When it is necessary to clean the heat sinks 2, first, pinch the two dial plates 6 with the index finger and thumb at both ends of the U-shaped frame 1 at the same time, so that the clamping block 5 is separated from the docking groove 32 on the arched frame 3. At this time, the two arched frames 3 can be removed from the U-shaped frame 1, and then the heat sinks 2 can be pulled out from the card slots 13 at the inner bottom of the U-shaped frame 1 in sequence to wipe and clean the heat sinks 2, which can effectively clean the heat sinks, and the installation and fixation of the heat sink 2 structure can be completed according to the reverse operation of the disassembly process, restoring the heat dissipation effect of the heat sink 2 and extending the service life.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the width dimension of the inner side surface of the positioning groove 11 is the same as the thickness dimension of the heat sink 2, and the bottom of the heat sink 2 protrudes by a part with the same dimension as the inner side surface of the positioning groove 11. The protruding part at the bottom of the heat sink 2 is inserted into the inner side surface of the positioning groove 11. When installing the heat sink 2, the heat sink 2 can be preliminarily arranged and positioned, facilitating subsequent operations.

[0035] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a plurality of splicing grooves 31 are equidistantly arranged at the bottom of the arched frame 3. The splicing grooves 31 at the bottom of the arched frame 3 are respectively installed on each heat sink 2. The width dimension of the inner side surface of the splicing groove 31 is the same as the thickness dimension of the heat sink 2. There is a convex block between every two splicing grooves 31 at the bottom of the arched frame 3, and the two side surfaces of the convex block are respectively attached to the side surfaces of two adjacent heat sinks 2. Moreover, the side surfaces of the convex blocks at both ends of the bottom of the arched frame 3 are respectively attached to the two inner side surfaces of the U-shaped frame 1, thereby effectively supporting the arrangement orientation of the heat sinks 2 and preventing the heat sinks 2 from shaking.

[0036] In this embodiment, as Figure 2 and Figure 5 shown, the parts of both sides of the arched frame 3 above the top edge of each splicing groove 31 are clamped into the inside of the clamping groove 21 at the top of the heat sink 2, and the top of the arched frame 3 is flush with the top of the heat sink 2 and the top of the U-shaped frame 1, thereby making the overall structure more regular.

[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 4 shown, a round hole is opened at the inner bottom of the positioning groove 11. A first spring 4 is installed inside the round hole. The top of the first spring 4 is squeezed by the bottom of the arched frame 3, causing the first spring 4 to contract into the inside of the round hole. Therefore, without external pressure, the first spring 4 can push the arched frame 3 upward.

[0038] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the sliding rod 7 is located inside the storage groove 14, and one end of the sliding rod 7 slides through the sliding groove 12 and is fixedly connected to one end of the dial plate 6. One end of the second spring 8 is fixedly connected to one end of the inner side surface of the storage groove 14, and the other end of the second spring 8 is fixedly connected to one end of the clamping block 5. Without external force, the second spring 8 will drive the sliding rod 7 to slide so that the clamping block 5 is located in the positioning groove 11. Moreover, since the top of the clamping block 5 is arc-shaped, after being pressed at its top, the clamping block 5 can be squeezed into the storage groove 14, so that the docking groove 32 can catch the clamping block 5.

[0039] Working principle: When the heat sink structure is in use, first insert the protruding part at the bottom of the heat sink 2 into the inner side of the positioning groove 11, and then use the splicing groove 31 on the arch-shaped frame 3 to clamp the top of the heat sink 2, and insert both ends of the arch-shaped frame 3 into the inner side of the positioning groove 11. At this time, when both ends of the arch-shaped frame 3 slide downward on the inner side of the positioning groove 11, the top of the clamping block 5 can be squeezed, so that the clamping block 5 slides into the inner side of the receiving groove 14. When the bottom of both ends of the arch-shaped frame 3 fits with the inner bottom of the positioning groove 11, the clamping block 5 is snapped into the docking groove 32. When it is necessary to clean the heat sink 2, first pinch the two dial plates 6 with the index finger and thumb at both ends of the U-shaped frame 1 at the same time, so that the clamping block 5 is separated from the docking groove 32 on the arch-shaped frame 3. At this time, the spring 4 pushes up the arch-shaped frame 3, and the two arch-shaped frames 3 can be removed from the U-shaped frame 1. Then, the heat sink 2 can be pulled out from the card slot 13 at the inner bottom of the U-shaped frame 1 in turn to wipe and clean the heat sink 2, which can effectively clean the heat sink and restore the heat dissipation effect of the heat sink 2, and improve the service life.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
