Claims16
Fluorinated nitrocompounds having a general formula selected from (I) and (II):
- wherein
- (i) X, Y and Z are independently selected from:
- halogen,
- hydrogen,
- partially or fully halogenated C1-C4 alkyl,
- with the proviso that at least one of X, Y or Z is a halogen, and
- (ii) Re is selected from any C1-C7 linear, branched, saturated or unsaturated, or C5-C7 cyclic, saturated or unsaturated carbon chain which can comprise 0-5 heteroatoms selected from O and S, and can be, optionally, partially or fully halogenated;
- with the proviso that if Re is CF3 at least one of X, Y and Z is not F.
A method for exchanging heat with an object said method comprising using a heat transfer fluid wherein said heat transfer fluid comprises one or more fluorinated nitrocompounds having a general formula selected from (I) and (II):
- wherein
- (i) X, Y and Z are independently selected from:
- halogen,
- hydrogen,
- partially or fully halogenated C1-C4 alkyl,
- with the proviso that at least one of X, Y or Z is a halogen, and
- (ii) Re is selected from any C1-C7 linear, branched, saturated or unsaturated, or C5-C7 cyclic, saturated or unsaturated carbon chain which can comprise 0-5 heteroatoms selected from O and S and can be, optionally, partially or fully halogenated.
A method according to claim, 2 wherein said one or more fluorinated nitrocompounds having a general formula selected from (I) and (II) make up at least 5% by weight of said heat transfer fluid.
An apparatus comprising an electronic computing equipment and a heat transfer fluid wherein said heat transfer fluid comprises one or more fluorinated nitrocompounds having a general formula selected from (I) and (II):
- wherein
- (i) X, Y and Z are independently selected from:
- halogen,
- hydrogen,
- partially or fully halogenated C1-C4 alkyl,
- with the proviso that at least one of X, Y or Z is a halogen, and
- (ii) Re is selected from any C1-C7 linear, branched, saturated or unsaturated, or C5-C7 cyclic, saturated or unsaturated carbon chain which can comprise 0-5 heteroatoms selected from O and S and can be, optionally, partially or fully halogenated.
An apparatus comprising a battery, a thermal management system for said battery, said thermal management system for said battery comprising a heat transfer fluid exchanging heat with said battery, wherein said heat transfer fluid comprises one or more fluorinated nitrocompounds having a general formula selected from (I) and (II):
- wherein
- (i) X, Y and Z are independently selected from:
- halogen,
- hydrogen,
- partially or fully halogenated C1-C4 alkyl,
- with the proviso that at least one of X, Y or Z is a halogen, and
- (ii) Re is selected from any C1-C7 linear, branched, saturated or unsaturated, or C5-C7 cyclic, saturated or unsaturated carbon chain which can comprise 0-5 heteroatoms selected from O and S and can be, optionally, partially or fully halogenated.
