Abstract

Highlights: A single-driving integrated pump and compressor electronic cooling system was proposed. Steady cooling performances of the two individual cooling modes were studied. Cooling results of the integrated system and the two individual modes were compared. Energy ratios of the two individual models under different air temperature were analyzed. Dynamic cooling performances of the integrated cooling system were investigated. Abstract: In this paper, a novel single-driving integrated pump and compressor system was developed to tackle the electronic cooling problem under a large range of ambient temperatures and heat loads. An experimental set-up was developed for this purpose. Experiments were conducted to evaluate the system performance under stable working conditions and investigate dynamic performance when the system was switched between liquid and vapor cooling modes. The results showed that liquid cooling mode had a large energy ratio with a restricted cooling performance at high air temperatures or heat fluxes while vapor cooling mode provided a better cooling performance at the expense of low energy ratio. Meanwhile, the system was well suited to handle quickly changing air temperatures and heat loads by switching between liquid and vapor cooling modes. Therefore, the integrated system was proven to be well applied in the two-phase cooling system to provide energy savings and temperature stability.
