The central processing unit (CPU) is the most critical component of the computer’s hardware. During operation, the CPU produces heat, just like any other electronics devices, and it must be effectively cooled in order to operate at the peak best performance. In this work, alumina (Al2O3) nanofluid mixed water has been used as a cooling system for the CPU. Nanofluid refers to a working fluid that has nanoparticles mixed in a base fluid, such as water or ethylene glycol. To improve the current cooling system, the coolant fluid has been changed from distilled water to a nanofluid coolant. The main focus of this work is to design and modify the water cooling system and to test the performance of the nanofluid cooling system for the computer CPU. It has been found from the experiment testing that the water cooling system improved by using a nanofluid by 2.39%. The overall heat transfer coefficient between those two coolants has been calculated and compared. The overall heat transfer coefficient of nanofluid mixture is higher than for pure distilled water. The smart control system also provides a good monitoring system to the CPU working temperature. In conclusion, a nanofluid can be the best option for a CPU cooling system.

摘要

The central processing unit (CPU) is the most critical component of the computer’s hardware. During operation, the CPU produces heat, just like any other electronics devices, and it must be effectively cooled in order to operate at the peak best performance. In this work, alumina (Al2O3) nanofluid mixed water has been used as a cooling system for the CPU. Nanofluid refers to a working fluid that has nanoparticles mixed in a base fluid, such as water or ethylene glycol. To improve the current cooling system, the coolant fluid has been changed from distilled water to a nanofluid coolant. The main focus of this work is to design and modify the water cooling system and to test the performance of the nanofluid cooling system for the computer CPU. It has been found from the experiment testing that the water cooling system improved by using a nanofluid by 2.39%. The overall heat transfer coefficient between those two coolants has been calculated and compared. The overall heat transfer coefficient of nanofluid mixture is higher than for pure distilled water. The smart control system also provides a good monitoring system to the CPU working temperature. In conclusion, a nanofluid can be the best option for a CPU cooling system.
