Experimental investigation on the heat transfer characteristics of vacuum spray flash evaporation cooling

Abstract: a b s t r a c tVacuum spray flash evaporation cooling (VSFEC) is considered as an alternative effective method for dissipating high heat flux in the field of space thermal control. In this paper, a VSFEC experiment system has been developed to investigate the influence of spray flow rate and spray height on the heat transfer characteristics of VSFEC. The experiment results show that the heat flux can be removed efficiently from the heat source in VSFEC system with a very small spray flow rate, which is only on… Show more

“…The typical working condition of 30°nozzle angle, 3.3 mm spray height, and 3.95 L•h −1 flow rate of working medium was studied in the experiment. Cheng et al [46] improved the heating system of the heating surface to realize larger heat accumulation (Figure 8(c)). In the experiment, the commercial DANFOSS nozzle which has a pore size of 0.5 mm and a nozzle angle of 45°was used.…”
