Claims13
A liquid dielectric coolant comprising a combination consisting essentially of a monoalcohol fatty acid ester and a diester, wherein the weight ratio of monoalcohol fatty acid ester/diester is comprised between 15/85 and 55/45, and wherein the combination of monoalcohol fatty acid ester and diester is:
- isoamyl isostearate and propylene glycol di-caprate/di-caprylate,
- isoamyl laurate and propylene glycol di-caprate/di-caprylate, or 2-ethylhexyl laurate and di-2-ethylhexyl sebacate.
