Immersion cooling of an array of heated elements by convective boiling of a subcooled binary liquid mixture
- California Univ., Berkeley (USA)
Boiling data and the critical heat flux conditions are reported for both channel flow and jet impingement flow using varying concentrations of R-11 in R-113. An array of ten flush-mounted heated elements on one wall of a vertical passage were cooled by subcooled boiling. Data indicate that for this binary system the addition of R-11 to R-113 does not produce a significant change in critical heat flux. For channel flow boiling, the data indicate that addition of a small amount of a less volatile component slightly increases the critical heat flux, whereas addition of a small amount of more volatile component decreases it. The critical heat flux data were also found to agree well with critical heat flux correlations for pure fluids if the mole-weighted mean properties of the mixture were used to compute the critical heat flux from the pure fluid correlation. The significance of the findings of this study with regard to the use of binary mixtures of dielectric fluids for immersion cooling of electronic components is also discussed in this paper. 9 refs.
