Abstract
Creating thermal well-being and comfort for humans is now very natural and necessary. From the point of view of ensuring optimal operating conditions for electronic and electrical equipment, it is very important to provide a cooling system. For this reason, the research work deals with the creation of optimal conditions for rising temperatures in rooms with electronics. A combination of cooling systems is proposed to reduce the heat load of electronic components. The first part of the work generally describes the requirements for the design of refrigeration equipment and methods of heat dissipation by natural or forced convection. Depending on the requirement for low-energy equipment, a cooling system with a gravitational heat pipe and fans was designed in the second part of the work. The cooling system was installed in a closed electrical cabinet. The resulting values of the measurements indicated the evaluation of the transferred heat output in free and forced convection. The research also points to a comparison of the individual flow directions created by the fans.
Highlights
Adjusting the temperature and properties of the air in a room is a natural part of a person's comfort
It follows that the heat pipe is not able to provide heat dissipation by free convection at such a heat load
The field of application of the research was focused on reducing the temperature in the spaces of electronic elements that produce waste heat during their operation
Summary
Adjusting the temperature and properties of the air in a room is a natural part of a person's comfort. Various devices that have been manufactured directly are used to increase, decrease the temperature or to adjust the humidity. Most of them depend on the source of electricity in their activities. Many research works focus on the use of passive methods in ensuring the thermal comfort of a person or on the maintenance-free and safe operation of equipment. This scientific work, which focuses on cooling systems in electrical engineering, is moving in the direction of passive operation of equipment
