Numerical simulation of a single oriented mini-pipe for electronic cooling systems
Resumen
Los mini-tubos son componentes críticos en los sistemas de enfriamiento para electrónica, requiriendo diseño preciso para optimizar el desempeño. Dentro de estos tubos, flujo líquido o bifásico circula a través de trayectorias orientadas. La simulación numérica es esencial para la optimización del diseño. Este artículo introduce un algoritmo propio que, basado en un modelo unidimensional en estado estacionario, permite el cálculo de parámetros claves de funcionamiento para un mini-tubo orientado con R1336mzz(Z) como el fluido de trabajo, demostrando la utilidad del algoritmo. El análisis proporciona información valiosa de la relación entre los parámetros de diseño y el funcionamiento del sistema. Los resultados indican que el funcionamiento óptimo se alcanza al maximizar el diámetro interno del tubo y minimizar la inclinación del tubo. Más aún, este algoritmo sirve como herramienta valiosa para la simulación de sistemas de enfriamiento en micro-escala, permitiendo la optimización del diseño y la predicción del funcionamiento antes del desarrollo de instalaciones experimentales.
