Description

technical field [0001] The invention relates to a cooling system, in particular to a computer water cooling system based on pulsating flow. Background technique [0002] With the development of semiconductor technology, the integration of chips is getting higher and higher. The more electronic components are integrated per unit area, the greater the heat generation. A large amount of heat is distributed on a smaller surface, which has a negative impact on the reliability of the chip. Big threat. Therefore, the heat dissipation of the chip is particularly important. The current computer CPU power is getting bigger and bigger, reaching more than 100 watts. Players who overclock and play large-scale games make the CPU "hot". In order to use the computer smoothly and prolong the life of the chip, efficient heat dissipation is essential. [0003] Computer heat dissipation mainly includes air cooling, heat pipe, water cooling and other methods. At present, most computers use air...

These methods have their own advantages and disadvantages. Now compare the air cooling and water cooling commonly used in desktop computers.

Air cooling takes up little space, but has low heat dissipation efficiency and high noise. The vibration of the fan directly attached to the CPU is not good for the CPU and the motherboard; water cooling has good heat dissipation effect and low noise, but requires pumps, cooling radiators, and multiple water pipes, resulti
