Nucleate pool boiling heat transfer performance of SES36 refrigerant at different saturation pressure for two-phase immersion cooling applications

The two-phase immersion cooling of high heat flux generating electronic components is becoming essential as it enables high heat dissipation at lower wall superheat temperature. In the present study, pool boiling heat transfer performance of SES36 refrigerant on copper heater surface is investigated under saturated boiling conditions. The effect of saturation pressure on critical heat flux and heat transfer coefficient is studied by varying saturation pressure from 75 kPa to 200 kPa. The critical heat flux and heat transfer coefficient enhanced by 3.5% and 92.3%, respectively, with an increase in saturation pressure from 75 kPa to 200 kPa.
