Mathematical Modeling of a Microprocessor’s Liquid Cooling System

This study examines the efficiency of a microprocessor’s cooling system and maintaining the optimal temperature of electronic components. To do this, experiments are carried out on the existing cooling system of the microprocessor with control of all main parameters, primarily such as the temperature and coolant flow, as well as the performance and temperature of the processor. Based on the data obtained, a mathematical model is built that describes the change in the microprocessor’s power and allows us to calculate the temperatures and speeds of coolants, as well as obtain the most effective modes for the operation of the cooling system. The obtained experimental data and mathematical model make it possible to predict the required power of the cooling system and the operating parameters of microelectronic components, which is especially important when new generations of microprocessors with the highest performance appear. The data obtained also makes it possible to calculate parameters for existing processors in order to maximize the efficiency and reliability of their operation, which is also relevant for other electronic devices, in particular microcontrollers.
