Description

Technical Field

[0001] The utility model relates to the technical field of computer CPU heat dissipation, in particular to a computer CPU heat dissipation device. Background Art

[0002] With the rapid development of computer technology, the performance of CPUs has been continuously improved, and the heat generated has also been increasing. In order to ensure the stable operation of the CPU, an efficient heat dissipation device is essential. The main function of a computer CPU heat dissipation device is to quickly dissipate the heat generated by the CPU to prevent the CPU from being damaged due to excessive temperature. In various computer application scenarios, whether it is a high-performance gaming computer or a commercial computer for office and data processing, a reliable heat dissipation device is required to maintain the stable operation of the system. With the advancement of technology, people's requirements for computer heat dissipation devices are getting higher and higher. Not only do they require good heat dissipation performance, but they also expect them to be easy to maintain and easy to clean.

[0003] Currently, common computer CPU cooling devices are mainly divided into two types: air cooling and water cooling. Air cooling devices usually consist of heat sinks, fans, and heat pipes. Their working principle is to transfer heat generated by the CPU to the heat sink through the heat pipes. The fan then blows air through the heat sink to remove the heat. Water cooling devices consist of a water cooling head, water pipes, water pumps, water tanks, and radiators. Their working principle is that the water cooling head contacts the CPU, transferring heat to the coolant. The coolant is then driven by the water pump to flow through the water pipes to the radiator. The radiator exchanges heat with the air, and the cooled coolant flows back to the water cooling head, and the cycle repeats.

[0004] Existing computer CPU cooling devices have a significant problem during actual use: they lack an effective filter structure and are difficult to disassemble and clean. This results in a gradual decrease in cooling performance over time. Due to the lack of a filter, dust and other impurities in the air easily enter the cooling device and come into contact with components such as the heat sink and fan. Over time, this accumulation can affect air circulation and reduce cooling efficiency. Furthermore, traditional cooling devices are often complex in structure and design, and the disassembly process is cumbersome, requiring specialized tools. This significantly inconveniences users' daily maintenance. When dust accumulates inside the cooling device, it becomes difficult for users to effectively clean it, further impacting the cooling device's performance and potentially shortening the CPU's lifespan, affecting the overall stability of the computer. Therefore, a computer CPU cooling device is proposed to address this issue. Utility Model Content

[0005] In order to make up for the above shortcomings, the present invention provides a computer CPU heat dissipation device, which aims to improve the problem in the prior art that there is no filter and the entire device is difficult to disassemble and clean, resulting in poor heat dissipation.

[0021] A second spring is provided inside the fixing column, one side of the second spring is fixedly connected to the inner wall of the fixing column, and the other end of the second spring is fixedly connected to a partition.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the user can manually turn the wrench to drive the movable column in the protective cover to move, and the displacement of the movable column causes the baffle to move synchronously, thereby compressing the spring 1 and allowing the movable column to move out of the frame range to release the lock on the filter. At this time, the user can lift the handle, and the handle drives the connecting column to move, and the displacement of the connecting column causes the filter to move, thereby achieving the effect of quickly removing the filter. This solves the problem that the traditional heat dissipation device has no filter and the entire device is difficult to disassemble and clean, resulting in poor heat dissipation, and improves the service life and heat dissipation efficiency of the heat dissipation device.

[0024] 2. In the present invention, when the CPU needs to be supplemented with silicone grease during maintenance, the user turns the knob, and the rotation of the knob drives the sliding column to rotate accordingly, and the rotation of the sliding column causes the limit column to move.

When the limiting post 21 rotates to a certain angle, the positional relationship with the L-shaped groove 23 on the fixing post 22 changes, and the lock of the sliding post 20 is released. At this time, the spring 24 inside the fixing post 22 begins to rebound, and the spring 24 pushes the partition 25 to move.

[0037] Working principle: During routine maintenance of the computer CPU cooling device, the user can manually turn the wrench 14 to rotate it. The rotation of the wrench 14 drives the movable column 13 located inside the protective cover 12 to move. The displacement of the movable column 13 drives the baffle 16 to move as well, thereby compressing the spring 15 and causing the movable column 13 to move out of the range of the frame 17, thereby releasing the lock on the filter 5. The user can then move the handle 6 by hand, which drives the connecting column 7 to move. The displacement of the connecting column 7 promotes the displacement of the filter 5, thereby achieving In order to achieve the effect of quickly removing the filter 5, when the CPU needs to be supplemented with silicone grease during maintenance, the user first turns the knob 18. At this time, the rotation of the knob 18 drives the sliding column 20 to rotate, and the rotation of the sliding column 20 also drives the displacement of the limiting column 21. When the limiting column 21 rotates to a certain angle, the spring 24 inside the fixed column 22 begins to rebound, pushing the partition 25 to move. The displacement of the partition 25 drives the displacement of the sliding column 20, so that the entire device can be separated from the bottom, thereby achieving the effect of quickly disassembling the entire heat dissipation device.
