Simulation of Thermal Energy Removal from Processors Using Air Coolers

Abstract

The results of a study on the removal of thermal energy from processors using air coolers (AC) are presented. Four experiments were carried out, in which, with the help of three-dimensional solid-state parametric modeling of various versions of the AC, the most effective ones were identified. In the first experiment, a tower radiator with a supporting structure in the form of copper bars and a vertically mounted fan was developed, which made it possible to determine the efficiency of heat transfer through the radiator. In the next experiment, in the previously developed model, copper bars were replaced with heat pipes and the fan was removed, which made it possible to substantiate the need for the presence or absence of airflow with a gradual increase in processor power during its operation. In the third case, the possibility of changing the fan speed was implemented, which made it possible to set the maximum air flow rate for efficient cooling of the radiator. In the last experiment, the optimal design of the AC was established, which made it possible to effectively implement the dissipation of thermal energy from the processor at various power levels. The necessity of using AC in such modern technical means as personal computers, servers, computer systems, etc., in which there are no restrictions on providing weight and size parameters has been experimentally proved.
