The effect of changes in the fluid flow rate of Virgin Coconut Oil (VCO) on the immersion cooling process

Abstract

The cooling system in computer equipment generally uses a conventional fan, where the heat transfer occurs by radiation so that the level of heat absorption is not optimal in computer components that generate heat. In overcoming these problems, a cooling system using the immersion cooling method is used. The use of an immersion cooling system on computer equipment aims to compare the temperature drop on CPU performance using conventional cooling and immersion cooling. In testing the computer system will be operated for 24 hours with maximum CPU performance. Variations of the immersion cooling system in the form of flow rates of 2, 4 and 6 lpm with variations in the rotation of the radiator fan at 200, 400 and 600 rpm. The results of the test show that the temperature reduction that can be achieved by conventional cooling is 71.2°C, while the temperature decrease in the immersion cooling system with the best variation is at a water rate of 6 lpm and a fan rotation of 600 rpm is 42.8°C. The results of the test can be seen that the immersion cooling system can significantly reduce the working temperature of the CPU.
