Análise da Transferência de Calor em Sistemas de Refrigeração de Unidades de Processamento de Dados

Abstract

The highest operational temperature for a CPU without interruption is 90 °C. When processor TDP is high, conventional heat sinks may be inadequate under full load. This study investigates thermal transfer using the DTML method in a liquid cooling system for an Intel® Core™ i5-3330 processor at 3.0GHz. The experiment used a Thermaltake cooling kit, measuring flow rate, inlet and outlet fluid temperatures in the water block. Results showed that under full workload, the CPU reached 75°C with a standard cooler and 53°C with the watercooler, leading to operational efficiency and an energy saving of 0.439 W compared to a traditional heat sink.
