Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to an efficient heat dissipation device. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. Generally, a layer of thermal grease needs to be applied on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink. With the progress of technology, the heat sink is also developing rapidly.

[0003] The Chinese patent with the publication number of CN206775905U discloses an efficient heat dissipation device, which will not form a hot air layer due to large heat dissipation, blocking the fins from dissipating heat. Through diamond-shaped, triangular and serrated heat dissipation bars and heat dissipation blocks, corresponding heat dissipation components can be selected according to different heat dissipation requirements.

[0004] Although the heat dissipation device in the above-mentioned prior art can dissipate heat, the heat dissipation fins are fixedly arranged. This leads to that during long-term use, if a single fin is damaged, the heat dissipation effect of the entire heat dissipation device will be affected, and the practicability is poor. Moreover, most of the existing heat dissipation devices are fixed by a single bolt during installation, which leads to the phenomenon that the bolt is easily loosened under external force. Therefore, we propose an efficient heat dissipation device. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides an efficient heat dissipation device, which has the function that when a single heat dissipation fin is damaged, it can be taken off separately and then a new heat dissipation fin can be installed. There is no need to replace the entire heat dissipation device. When replacing, only need to rotate the rotating block so that the notch on the limiting bar is above the connecting block, and at this time, the damaged heat dissipation fin can be pulled out, greatly reducing the maintenance cost of the heat dissipation device.

[0006] The technical solution of the utility model is: an efficient heat dissipation device, comprising:

[0007] A base, the shape of the base is set as a rectangle, and heat dissipation fins are arranged above the base in a dense equidistant distribution;

[0008] A replacement mechanism, the replacement mechanism is arranged on the top of the base, and two groups of the replacement mechanisms are symmetrically distributed on the front and rear sides of the heat dissipation fins, and are used for removing and replacing the heat dissipation fins after they are damaged;

[0009] Fixing components are arranged on the top of the base. Four groups of the fixing components are distributed in a rectangle at the four corners of the top of the base and are used to fix the high-efficiency heat dissipation device on the main body of the device that needs heat dissipation.

[0010] In a further technical solution, the replacement mechanism includes a movable groove opened on the top of the base. A lead screw is movably connected to the inner side of the movable groove through a bearing. A limiting strip is threadedly connected to the outer side of the lead screw. An installation groove is opened on the top of the base. An installation block is fixedly connected to the bottom of the heat dissipation fin. Connecting blocks are fixedly connected to both the front and rear sides of the installation block.

[0011] In a further technical solution, connecting grooves are opened on both the front and rear sides in the installation groove. The other side of the connecting groove is communicated with the inside of the movable groove. The outer side of the connecting block is adapted to the inner side of the connecting groove.

[0012] In a further technical solution, sliders are fixedly connected to the outer sides of the two limiting strips away from each other. A sliding groove is opened on the inner side of the movable groove. The sliders are slidably connected to the inner side of the sliding groove.

[0013] In a further technical solution, a notch is opened on the top of the limiting strip. The left end of the lead screw penetrates through the left side of the movable groove and extends outside the base. A rotating block is fixedly connected to the left end of the lead screw.

[0014] In a further technical solution, the fixing component includes an installation hole opened on the top of the base. A bolt is arranged inside the installation hole. A nut is threadedly connected to the outer side of the bolt. A side block is fixedly connected to the outer side of the nut.

[0015] In a further technical solution, a screw hole is opened on the top of the side block. A screw is threadedly connected to the inside of the screw hole. The bottom end of the screw penetrates through the side block and extends into the inside of the base.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By setting the replacement mechanism, during the use process, when a single heat dissipation fin is damaged, it can be taken off separately and then a new heat dissipation fin can be installed. There is no need to replace the entire heat dissipation device. When replacing, only need to rotate the rotating block so that the notch on the limiting strip is located above the connecting block. At this time, the damaged heat dissipation fin can be pulled out, which greatly reduces the maintenance cost of the heat dissipation device and makes the high-efficiency heat dissipation device have good practicability.

[0018] 2. By providing a fixing component, the high-efficiency heat dissipation device of the present utility model can be fixed at an appropriate position of the equipment under the action of bolts and nuts during use. Then, the screw is rotated and screwed into the inside of the base. Under the action of the screw and the side block, the nut can be prevented from rotating, ensuring the stability of the high-efficiency heat dissipation device after installation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the embodiments of the present utility model with reference to the drawings.

[0026] Embodiment:

[0027] As Figures 1-4 shown, a high-efficiency heat dissipation device includes:

[0028] A base 1, the shape of the base 1 is set to be rectangular, and heat dissipation fins 2 are arranged above the base 1 in a dense equidistant distribution;

[0029] A replacement mechanism 3, the replacement mechanism 3 is arranged on the top of the base 1, and two groups of replacement mechanisms 3 are symmetrically distributed on the front and back sides of the heat dissipation fins 2, and are used to remove and replace the heat dissipation fins 2 after they are damaged;

[0030] A fixing component 4, the fixing component 4 is arranged on the top of the base 1, and four groups of fixing components 4 are distributed in a rectangle at the four corners of the top of the base 1, and are used to fix the high-efficiency heat dissipation device on the main body of the equipment that needs heat dissipation.

[0031] The working principle of the above technical solution is as follows:

[0032] Fix the base 1 on the device that needs heat dissipation through bolts 404 and nuts 401, and then fix the position of the nut 401 through screws 402 and side blocks 403. Under the action of the heat dissipation fins 2 distributed densely at equal intervals, the device is cooled efficiently and quickly. After long-term use, if one or more heat dissipation fins 2 are damaged, at this time, rotate the rotating block 303 to rotate the lead screw 307, so that it drives the limiting strip 302 to move until the notch 301 opened at the top of the limiting strip 302 moves above the corresponding moving block and then stop. At this time, the damaged heat dissipation fin 2 can be disassembled and replaced, and then rotate the rotating block 303 in the reverse direction to reset the limiting strip 302.

[0033] In another embodiment, as Figure 3 shown, the replacement mechanism 3 includes a movable groove 306, which is opened on the top of the base 1. The inner side of the movable groove 306 is movably connected with a lead screw 307 through a bearing. The outer side of the lead screw 307 is threadedly connected with a limiting strip 302. An installation groove 304 is opened on the top of the base 1. The bottom of the heat dissipation fin 2 is fixedly connected with an installation block 310, and both the front and rear sides of the installation block 310 are fixedly connected with connection blocks 309.

[0034] Under the action of the movable groove 306, it is convenient for the limiting strip 302 to move. Under the action of the limiting strip 302, the position of the connection block 309 is limited from above, so as to fix the heat dissipation fin 2. Under the action of the lead screw 307, the limiting strip 302 can be driven to move. Under the action of the installation block 310, the heat dissipation fin 2 can be installed.

[0035] In another embodiment, as Figure 3 shown, connection grooves 305 are opened on both the front and rear sides in the installation groove 304. The other side of the connection groove 305 is communicated with the inside of the movable groove 306. The outer side of the connection block 309 is adapted to the inner side of the connection groove 305.

[0036] Under the action of the connection groove 305, it is convenient for the connection block 309 to be placed. Under the action of the limiting strip 302, the connection block 309 is limited from the top. Under the action of their adaptation, the stable installation of the heat dissipation fin 2 can be ensured.

[0037] In another embodiment, as Figure 3 shown, sliding blocks 308 are fixedly connected to the far sides of the two limiting strips 302. A sliding groove is opened on the inner side of the movable groove 306, and the sliding blocks 308 are slidably connected to the inner side of the sliding groove.

[0038] Under the action of the sliding blocks 308 and the sliding grooves, the moving track of the limiting strip 302 is limited to ensure that it can only move in the left-right direction.

[0039] In another embodiment, as Figure 3 shown, a notch 301 is formed at the top of the limiting strip 302. The left end of the lead screw 307 penetrates through the left side of the movable slot 306 and extends outside the base 1. A rotating block 303 is fixedly connected to the left end of the lead screw 307.

[0040] Under the action of the notch 301, it is convenient to take out and put in the connecting block 309, so as to facilitate the installation and disassembly of the heat dissipation fins 2. Under the action of the rotating block 303, it is convenient to rotate the lead screw 307.

[0041] In another embodiment, as Figure 3 shown, the fixing assembly 4 includes a mounting hole 405 which is formed in the top of the base 1. A bolt 404 is arranged inside the mounting hole 405. A nut 401 is threadedly connected to the outside of the bolt 404. A side block 403 is fixedly connected to the outside of the nut 401.

[0042] Under the action of the mounting hole 405, it is convenient for the bolt 404 to penetrate. Under the action of the nut 401 and the bolt 404, the base 1 can be fixed. Under the action of the side block 403, the position of the nut 401 can be limited.

[0043] In another embodiment, as Figure 3 shown, a screw hole is formed in the top of the side block 403. A screw 402 is threadedly connected to the inside of the screw hole. The bottom end of the screw 402 penetrates through the side block 403 and extends into the inside of the base 1.

[0044] Under the action of the screw 402, the position of the side block 403 is limited to prevent the nut 401 from automatically rotating under the action of external force.

[0045] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
