Abstract
Two-phase evaporative cooling technology has been widely used for the electronic cooling. In this paper,
dynamic performance of an integrated pumping and compression evaporative electronic cooling system
was experimentally and theoretically investigated during the system mode variation. A mathematical
model was developed based on the ANSYS fluent and validated using experimental data. The results
showed a sharp increase in the cooling temperature before the stable cooling condition was achieved
as the system operating mode changed to meet the heat load variation. The model was then used to
investigate the influence of the different opening and closing order of the valves on the flow rate distributions
when the cooling system was switched from liquid-pumping mode to vapor-compression mode.
The results showed that the valve sequences had a large influence on the flow distributions during the
switching process. This valve sequence substantially influenced the cooling peak temperature when
the control time for the whole switching process was longer than 16 s. This analysis indicated that an
appropriate valve sequence could reduce the sharp change of cooling temperature and increase the cooling
performance during the system switching process.
