Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation system for passive heat dissipation of a computer. Background technique [0002] When the computer is working, the operation of its internal components will generate a lot of heat. If there is no heat dissipation system to discharge the heat in time, it will seriously affect the normal operation of the computer, resulting in slow operation of the computer, crashes, and even possible CPU failures. Core components are burned and other issues. [0003] Existing computer heat dissipation methods are generally divided into water-cooled heat dissipation and air-cooled heat dissipation, both of which belong to active heat dissipation. [0004] The air-cooled heat dissipation system includes a heat sink and a cooling fan. The principle is to conduct the heat from the heat source to the heat sink, and then drive the air to flow through the fan to achieve heat ...

AI Technical Summary

Problems solved by technology

[0004] The air-cooled heat dissipation system includes a heat sink and a cooling fan. The principle is to conduct the heat from the heat source to the heat sink, and then drive the air to flow through the fan to achieve heat dissipation; the disadvantage is that in order to ensure the effectiveness of the fan cooling, the computer case must be It is designed as an open structure, so that the interior of the chassis can communicate with the outside world. After a long period of use, the fan will bring the external dust into the machine, which not only affects the cleanliness of the interior of the chassis, but also a large amount of dust accumulated on the heat sink will easily cause heat sink damage. Reduced cooling effect or even failure

[0005] The water-cooling system includes pipelines, water-cooling liquid, and water pumps. The principle is to generate pressure through the water pump to circulate the water-cooling liquid along the pipelines inside the chassis to take away heat. The disadvantage is that the water-cooling system must be completely sealed, but the pipeline There are too many connection points, which put forward high requirements for the production and installation process. Once a certain connection point leaks, it will cause serious safety hazards to the computer. At the same time, the water pump itself is an electrical product with a low safety factor. Not only does it consume a lot of power, but it is also prone to malfunctions during use and is not easy to maintain. Once the water pump stops working, there will be problems with the entire water-cooling system, which cannot dissipate heat and cause damage to the computer.
