“…Published literature has investigated the thermal properties of hydrofluoroethers (HFE), [C 3 F 7 OCH 3 ], and fluorinated ketone (FK), [C 2 F 5 C(O)CF(CF 3 ) 2 ], and reported that they have comparable heat transfer performance with a commercial perfluorocarbon, which is FC 72 [6, 7]. Hence, these two new coolants have attracted attention.…”
