Theoretical study and experimental verification of the behaviour of a passive conditioning system for electronic components

摘要

The paper describes the theoretical determina- tion of the flow and the temperature distribution in a water natural circulation loop for passive conditioning of a big shelter for electronic components. A cylinder filled with phase change material in thermal connection with the inner of the shelter and with the ambient by a water nat- ural circulation loop forms the system. The system operates in natural convection, consequently during the daytime the water flow in the exchanger is stopped because the external temperature is greater then the melting tem- perature.
