Technical Field
[0001] This utility model relates to the technical field of water-cooled heat dissipation devices, specifically a water-cooled heat dissipation device. Background Technology
[0002] Modern electronic devices have increasingly higher requirements for reliability, performance indicators, and power density. The thermal design of electronic devices is becoming more and more important. Power devices are key components in most electronic devices, and their working condition directly affects the overall reliability, safety, and service life of the device. In addition to effectively dissipating heat, the heat dissipation solution for power devices is also crucial for reliability. Water cooling is a heat dissipation system that uses liquid circulation to transfer heat. Compared with traditional air cooling, water cooling has better heat dissipation effect and lower noise level.
[0003] Existing water-cooling heat dissipation devices typically dissipate heat by having the heat emitted by the device come into contact with the evenly distributed serpentine pipes. However, this method can only remove the heat that is in contact with the pipes, which can easily lead to uneven heat dissipation and makes it difficult to clean the pipes, resulting in poor heat dissipation performance. In order to address these problems, the inventor proposes a water-cooling heat dissipation device to solve the above problems. Utility Model Content

[0019] 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.
[0020] Example: Figure 1-5 As shown, this utility model provides a water-cooled heat dissipation device, including a first heat-absorbing plate 1 and a second heat-absorbing plate 2. The first heat-absorbing plate 1 can be sealed and fitted with the second heat-absorbing plate 2. Both the first heat-absorbing plate 1 and the second heat-absorbing plate 2 have serpentine flow channels 6. After the first heat-absorbing plate 1 and the second heat-absorbing plate 2 are sealed and fitted, the flow channels 6 in the first heat-absorbing plate 1 and the second heat-absorbing plate 2 can be spliced to form a water flow channel. A sealing groove 7 is formed on the upper surface of the first heat-absorbing plate 1, and a sealing ring 8 is fixedly installed on the lower surface of the second heat-absorbing plate 2. The sealing ring 8 can be sealed within the sealing groove 7. Both the first heat-absorbing plate 1 and the second heat-absorbing plate 2 have good thermal conductivity. The metal plates allow the first heat-absorbing plate 1 and the second heat-absorbing plate 2 to come into contact with the hot air emitted by the equipment, thereby increasing the contact surface of the hot air and making the heat dissipation more uniform. After the first heat-absorbing plate 1 and the second heat-absorbing plate 2 are sealed together, the guide grooves 6 inside the first heat-absorbing plate 1 and the second heat-absorbing plate 2 can be spliced into a water flow channel. The sealing ring 8 can improve the sealing performance of the first heat-absorbing plate 1 and the second heat-absorbing plate 2 after splicing, so that the coolant circulates in the guide grooves 6 inside the first heat-absorbing plate 1 and the second heat-absorbing plate 2. The heat is carried away by the circulating coolant to achieve cooling and heat dissipation, and it is also easy to clean the guide grooves 6, thereby improving the heat dissipation effect of the equipment.
[0021] A component box 3 is fixedly installed at one end of the first heat absorption plate 1. A heat dissipation box 9 is fixedly installed inside the component box 3. Multiple heat dissipation fins 15 are fixedly installed inside the heat dissipation box 9.
[0022] By adopting the above technical solution, the heat dissipation fins 15 are usually made of metal and have a large surface area to improve heat dissipation efficiency. When the coolant passes through the heat dissipation fins 15 in the heat dissipation box 9, the heat is transferred to these heat dissipation fins 15, and the purpose of cooling is finally achieved.
[0023] The heat dissipation box 9 has an inlet pipe 10 and a return pipe 11 fixedly installed at both ends, and one end of the inlet pipe 10 and the return pipe 11 is fixedly installed in the first heat absorption plate 1 and connected to the guide groove 6.
[0024] By adopting the above technical solution, the coolant in the heat sink 9 flows into the guide channel 6 through the inlet pipe 10, and then flows back into the heat sink 9 through the return pipe 11, thereby realizing the circulation of the coolant.
[0025] A water pump 12 is fixedly installed on the return water pipe 11, and the output end of the water pump 12 is connected to the return water pipe 11.
[0026] By adopting the above technical solution, the coolant is returned to the heat sink 9 by the water pump 12 through the return water pipe 11, thereby realizing the circulation of the coolant.
[0027] A liquid filling pipe 13 is fixedly installed on the top of the heat sink 9, and a sealing cap 14 is threaded onto the top of the liquid filling pipe 13.
[0028] By adopting the above technical solution, coolant can be added to the heat sink 9 through the liquid filling pipe 13.
[0029] The component box 3 has heat dissipation windows 4 at both the top and bottom, and the heat dissipation windows 4 are located at the heat dissipation box 9.
[0030] By adopting the above technical solution, the heat dissipation window 4 is conducive to the heat dissipation box 9 dissipating heat.
[0031] The second heat-absorbing plate 2 has fastening bolts 5 threaded into its four corners, and the fastening bolts 5 can be threaded into the first heat-absorbing plate 1.
[0032] By adopting the above technical solution, the first heat-absorbing plate 1 and the second heat-absorbing plate 2 are sealed and assembled together using fastening bolts 5.
[0033] Working Principle: In use, the first heat-absorbing plate 1 and the second heat-absorbing plate 2 are sealed and assembled together using fastening bolts 5 and installed inside the equipment. After the first heat-absorbing plate 1 and the second heat-absorbing plate 2 are sealed and fitted together, the guide grooves 6 inside the first heat-absorbing plate 1 and the second heat-absorbing plate 2 can be spliced to form a water flow channel, so that the first heat-absorbing plate 1 and the second heat-absorbing plate 2 come into contact with the hot air emitted by the equipment, thereby increasing the contact surface of the hot air and making the heat dissipation more uniform. The water pump 12 uses the return water pipe 11 to make the coolant flow back into the heat dissipation box 9, and the coolant in the heat dissipation box 9 flows into the guide groove 6 through the water inlet pipe 10 to realize the circulation of the coolant. The circulating coolant carries away the heat, thereby achieving cooling and heat dissipation. When the coolant passes through the heat dissipation fins 15 in the heat dissipation box 9, the heat is transferred to these heat dissipation fins 15, ultimately achieving the purpose of cooling. Moreover, the splicing and installation of the first heat-absorbing plate 1 and the second heat-absorbing plate 2 makes it easy to clean the guide groove 6, thereby improving the heat dissipation effect of the equipment.
[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
