2022/45/B/ST7/02820 project funded by NCN in the OPUS 23 competition. System cooling is an important problem in modern electronics. Among the most typical solutions that allow heat to be dissipated from the surface of electronic circuits to the environment is the use of a heat sink with forced gas or liquid flow.

Expected impact:
Based on the simulation results, a real cooling system will be built. It will be tested using a fast cooled thermal imaging camera. The results of the project will enable the development of the optimal design of IREC systems for cooling electronic circuits and systems, which may lead to their use on an industrial scale.
Description:
The cooling of electronic circuits is a significant problem for device manufacturers. Among the most typical solutions to dissipate heat from the surface of electronic circuits to the environment is the use of a heat sink with fan-forced cooling. In practice, this solution is often supported by, for example, heat pipes, additional fluid circulation or phase-change interface materials. However, in order to achieve better cooling efficiency, it is advisable to achieve a temperature in the system that is lower than ambient. For this purpose, the project authors propose to use a system cooling system operating in the Maisotsenko thermodynamic cycle. These systems are known as IREC (Indirect Regenerative Evaporative Cooling) technology, which has so far only been used for cooling and air conditioning in large industrial installations. The aim of the project will be to develop a numerical and physical model of a much smaller sized IREC system for cooling electronic circuits, in order to investigate its effectiveness and achievable performance. Based on the simulation results, a real cooling system will be built, which will then be tested using, among other things, a high-speed thermal imaging camera and measuring instruments. Their aim will be to determine its electro-thermal parameters. This will allow conclusions to be drawn regarding the optimal design of IREC systems for cooling electronic circuits, their predicted effectiveness and efficiency, as well as other parameters relevant to cooling system designers for electronics applications.
