Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices for computers, and particularly to a computer heat dissipation device. Background Art

[0002] A computer is a modern electronic computing device for high-speed computing. There are many components installed inside the computer case, such as a CPU, a motherboard, a graphics card, etc. These components will generate a large amount of heat during operation. After these components overheat, the computing speed of the computer will decrease, resulting in computer lag. Therefore, the computer case needs to have sufficient heat dissipation conditions to ensure that the temperature inside the case does not overheat; Existing heat dissipation mechanisms are usually of two types: water cooling and air cooling. Air cooling discharges the temperature inside the case through a heat dissipation fan. Although this structure is simple, it can only discharge the high-temperature hot air inside the case and cannot dissipate the heat generated by the operation of the components at the component installation locations. Water cooling usually cooperates with a condenser and a coolant, and cools the temperature near the components by installing cooling pipes near the components to achieve the purpose of cooling. However, the water cooling structure is cumbersome to install, and the cooling pipes need to be removed when replacing or inspecting the components, which is time-consuming and laborious and easily causes damage, affecting the service life of the device. Therefore, the above problems need to be solved. Summary of the Invention

[0020] Working principle: In this embodiment, the present invention also proposes a method for using a computer cooling device, including the following steps: Step 1: First, rotate the first limiting block 10 to remove it from the first limiting groove 5, and then pull out the push plate 2 from the inside of the chassis 1 through the handle 14. During this process, the pulley 17 cooperates with the second sliding groove 7 to reduce the resistance and friction during pulling. When the second limiting block 12 abuts against the top of the second limiting groove 8, install the computer components on the water-cooling mounting plate 16. After installation, push the push plate 2 back. After the third limiting block 13 is inserted into the third limiting groove 9, rotate the first limiting block 10 and insert it into the first limiting groove 5. Thus, the computer installation is completed. Step 2: Turn on the power supply, and the chassis 1 starts to run. Through the cooperation of the air inlet 4 at the top of the chassis 1 and the three exhaust fans 21 at the rear end of the chassis 1, it is convenient for the air circulation inside the chassis 1, and the inside of the chassis 1 is cooled by continuously inhaling cold air flow and exhausting hot air flow. The first filter plate 19 and the second filter plate 20 can intercept the dust in the air during exhaust. Step 3: Start the condenser 15 above the push plate 2, and transport the coolant inside the condenser 15 to the condensation cavity 11 through the condensation pipe. The condensation cavity 11 has two ends, an inlet and an outlet, which are respectively connected to the upper and lower condensation pipes of the condenser 15, accelerating the flow rate of the coolant inside the water-cooling mounting plate 16, so as to ensure that the water-cooling mounting plate 16 is always in a low-temperature state, and then cool the component installation location. Step 4: Start the motor 22 at the top inner wall of the chassis 1, drive the incomplete bevel gear 23 to rotate through the output shaft. The incomplete bevel gear 23 uses its unique shape characteristics to first engage and drive with the first bevel gear 24, thereby driving the lead screw 26 to rotate clockwise. When the incomplete bevel gear 23 rotates half a turn, it disengages from the first bevel gear 24 and engages and drives with the second bevel gear 25. At this time, the second bevel gear 25 drives the lead screw 26 to rotate counterclockwise. After rotating half a turn, the incomplete bevel gear 23 disengages from the second bevel gear 25 and engages and drives with the first bevel gear 24 again. Thus, the lead screw 26 can be driven by the motor 22 to rotate in a two-way intermittent manner. Step 5: When the lead screw 26 rotates, the mounting block 28 reciprocates left and right under the action of the first sliding rod 18. During the movement, the lower spur gear 29 engages and drives with the rack 27, thereby driving the spur gear 29 to rotate, and the spur gear 29 is fixedly connected to the cooling fan 30, so as to drive the cooling fan 30 to rotate. Thus, after the chassis 1 is powered on, the water-cooling mechanism can cool the water-cooling mounting plate 16, and the first air-cooling mechanism can accelerate the air flow rate inside the chassis 1 to cool down, and the motor 22 can also drive the cooling fan 30 to reciprocate left and right for targeted heat dissipation.
