Description

Technical Field

[0001] The utility model belongs to the technical field of heat sinks, and particularly relates to a high-efficiency heat sink rib structure. 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. For example, a relatively large heat sink is required for the CPU (Central Processing Unit) in a computer, and heat sinks are also required for the power tubes, line tubes in a television, and power amplifier tubes in a power amplifier.

[0003] At present, most heat sinks on the market are combined together to form a heat sink assembly. The overall structure is integrated. When a single heat sink is damaged, the entire heat sink assembly needs to be disassembled, which is difficult to operate. Moreover, the gap between the heat sinks is relatively small, resulting in difficulties for workers to disassemble and clean. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a high-efficiency heat sink rib structure, which solves the problems that the heat sink assembly composed of multiple heat sinks has an integrated overall structure and a relatively small gap between the heat sinks, resulting in difficulties for workers to disassemble and clean.

[0005] To achieve the above object, the utility model provides the following technical solution: A high-efficiency heat sink rib structure, including a mounting plate. Threaded columns are connected to both sides above the mounting plate. Mounting grooves are formed on the mounting plate. A plurality of fixing plates are connected to the mounting plate. A heat sink main body is slidably mounted between two fixing plates. Ventilation openings are formed on the heat sink main body. A heat conduction strip is connected to the heat sink main body. A spring is connected inside the heat conduction strip. One end of the spring is connected to a fixing block. A connecting plate is inserted on the threaded column. A sliding rod is connected to the connecting plate. A side plate is slidably connected to the sliding rod. A push plate is connected between two side plates. A plurality of scraping plates are connected to the side of the push plate facing the heat sink main body.

[0006] As a further scheme of the utility model: An endothermic plate is installed in the mounting groove. A plurality of heat conduction fins are connected to the endothermic plate. The heat conduction fins are in close contact with the heat conduction strip.

[0007] As a further scheme of the utility model: A cavity is arranged inside the heat sink main body. A plurality of inclined reinforcing plates are connected in the cavity. A vertical reinforcing plate is connected between two inclined reinforcing plates. The inclined reinforcing plates and the vertical reinforcing plate together form a triangular structure.

[0008] As a further scheme of the utility model: The scraping plates are arranged between two heat sink main bodies. Brushes are arranged on both sides of the scraping plates and on the side of the side plates facing the heat sink main body.

[0009] As a further solution of the present utility model: a connection groove is formed on the fixing plate, an inclined surface is provided at a position of the fixing plate close to the connection groove, and a fixing groove is formed on the groove wall of the connection groove.

[0010] As a further solution of the present utility model: fixing holes are formed at four corners of the mounting plate, the heat conducting strip slides in the connection groove, and the fixing block is fitted with the fixing groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this high-efficiency heat sink rib structure, by setting the connection groove, heat conducting strip, spring, fixing block and fixing groove, when the heat conducting strip is pushed into the connection groove, during the pushing process, the fixing block will be pushed by the fixing plate into the heat conducting strip, so that the fixing block can compress the spring. Thus, after the heat conducting strip completely enters the connection groove, the spring rebounds and pushes the fixing block into the fixing groove, thereby fixing the heat conducting strip and the heat sink main body to prevent sliding. The heat conducting strip that can slide in the connection groove enables the staff to quickly disassemble and install the heat sink main body, so as to facilitate the staff to maintain and clean a single heat sink main body.

[0013] 2. For this high-efficiency heat sink rib structure, by setting the threaded column, connecting plate, sliding rod, push plate, scraping plate, brush, inclined reinforcing plate and vertical reinforcing plate, the staff inserts the threaded column into the connecting plate, and then screws on the hexagonal nut on the threaded column to fix the connecting plate together with the sliding rod on the mounting plate. Thus, by reciprocally pushing the push plate, the push plate drives the scraping plate to slide between the heat sink main bodies, and then the attached dust is swept away by the brush to complete the cleaning work. The inclined reinforcing plate and vertical reinforcing plate in the heat sink main body can support the heat sink main body, and the triangular structure formed by the inclined reinforcing plate and vertical reinforcing plate can enhance the structural strength of the heat sink main body.

Specific implementation mode

[0020] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0021] As Figures 1 - 5 shown, the present utility model provides a technical solution: a high-efficiency radiator rib structure, including a mounting plate 1, threaded posts 2 are connected to both sides above the mounting plate 1, a mounting groove 3 is opened on the mounting plate 1, a heat absorbing plate 17 is installed in the mounting groove 3, and a plurality of heat conducting fins 18 are connected to the heat absorbing plate 17. The heat conducting fins 18 are in close contact with the heat conducting strip 7. The heat absorbing plate 17 absorbs the heat on the heating device, and the heat is transmitted to the heat conducting strip 7 through the heat conducting fins 18, and finally transmitted to the radiator main body 5 by the heat conducting strip 7, so as to absorb and dissipate the heat, reduce the temperature on the device to ensure the normal operation of the device.

[0022] A plurality of fixing plates 4 are connected to the mounting plate 1, and the radiator main body 5 is slidably installed between the two fixing plates 4. A connecting groove 22 is opened on the fixing plate 4, and an inclined surface is provided at a position of the fixing plate 4 close to the connecting groove 22. A fixing groove 23 is opened on the groove wall of the connecting groove 22. Through the inclined surface on the fixing plate 4, it is convenient for the fixing plate 4 to push the fixing block 9 to move, so as to facilitate the staff to push the heat conducting strip 7 into the connecting groove 22, thereby improving the installation and disassembly efficiency of the radiator main body 5.

[0023] Ventilation openings 6 are opened on the radiator main body 5, a cavity 19 is arranged inside the radiator main body 5, a plurality of inclined reinforcing plates 20 are connected in the cavity 19, and a vertical reinforcing plate 21 is connected between the two inclined reinforcing plates 20. The inclined reinforcing plates 20 and the vertical reinforcing plate 21 together form a triangular structure. The triangular structure formed by the connection of the inclined reinforcing plates 20 and the vertical reinforcing plate 21 enhances the structural strength of the radiator main body 5 and plays the role of a rib, while the ventilation openings 6 can increase the contact area between the radiator main body 5 and the air, thereby improving the heat dissipation efficiency.

[0024] A heat dissipation fin main body 5 is connected with a heat conduction strip 7. A spring 8 is connected inside the heat conduction strip 7. One end of the spring 8 is connected with a fixing block 9. Fixing holes 16 are opened at four corners of the mounting plate 1. The heat conduction strip 7 slides in the connection groove 22. The fixing block 9 is fitted with the fixing groove 23. Through the fitting of the fixing block 9 and the fixing groove 23, the position of the heat conduction strip 7 in the connection groove 22 is fixed, thereby preventing the heat dissipation fin main body 5 from sliding and falling due to the vibration generated during the operation of the device.

[0025] A connecting plate 10 is inserted on a threaded post 2. A sliding rod 11 is connected to the connecting plate 10. A side plate 12 is slidably connected to the sliding rod 11. A push plate 13 is connected between the two side plates 12. A plurality of scraping plates 14 are connected to the side of the push plate 13 facing the heat dissipation fin main body 5. The scraping plates 14 are arranged between the two heat dissipation fin main bodies 5. Brushes 15 are arranged on both sides of the scraping plates 14 and on the side of the side plates 12 facing the heat dissipation fin main body 5. When the push plate 13 is pushed, the side plates 12 will slide on the sliding rods 11, thereby guiding the movement of the scraping plates 14 through the two sliding rods 11, so that the push plate 13 and the scraping plates 14 can move smoothly.

[0026] The working principle of the present utility model is as follows:

[0027] The staff first fixes the connecting plate 10 on the threaded post 2 through a hexagon nut, and then pushes the heat conduction strip 7 into the connection groove 22. During the pushing process, the fixing plate 4 will push the fixing block 9 into the heat conduction strip 7 through the upper inclined surface, prompting the fixing block 9 to compress the spring 8. After the heat conduction strip 7 completely enters the connection groove 22, the spring 8 will rebound and push the fixing block 9 into the fixing groove 23, thereby fixing the heat conduction strip 7 in the connection groove 22. Through the sliding installation method, the staff can quickly install and disassemble the heat dissipation fin main body 5, thereby facilitating the staff to maintain or clean a single heat dissipation fin main body 5. During operation, the heat absorption plate 17 is attached to the heating device, so that the heat absorption plate 17 can absorb heat, and the heat will be transferred to the heat conduction strip 7 and the heat dissipation fin main body 5 through the heat conduction fins 18, and then the heat is dissipated through the heat dissipation fin main body 5 to reduce the device temperature. And the staff can push the push plate 13 back and forth, so that the push plate 13 drives the scraping plates 14 to slide between the heat dissipation fin main bodies 5, thereby sweeping away the attached dust through the brushes 15.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] The above describes in detail the preferred embodiments of the present patent. However, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the scope of knowledge possessed by those of ordinary skill in the art.
