Experimental investigation on system performances and transient response of a pumped two-phase battery cooling system using R1233zd
This study presents an experimental investigation on the pumped two-phase cooling system designed for battery thermal management. The experimental system was established with R1233zd as the refrigerant, and a dummy battery was used to simulate the heat generation during battery operation. The thermo...

This study presents an experimental investigation on the pumped two-phase cooling system designed for battery thermal management. The experimental system was established with R1233zd as the refrigerant, and a dummy battery was used to simulate the heat generation during battery operation. The thermodynamic cycle, wall temperature distribution of the cold plate and overall heat transfer coefficient were analyzed under steady state, while the transient response of the system with pump control was also studied. Results showed that the evaporating pressure of the system was not sensitive to the refrigerant mass flux, while it could be raised under higher heating loads. Both the refrigerant mass flux and vapor quality at the cold plate outlet showed little influence on the wall temperature distribution of the cold plate, however their effects on the overall heat transfer coefficient were different.
