Abstract (en)
[origin: EP2246523A1] A cooling apparatus (12) of a downhole tool (9, 11) comprises a turbine (13) driven by a drilling fluid (10) circulating in the downhole tool (9, 11), and a thermodynamic cooler (18). The cooling apparatus (12) further comprises a mechanical arrangement (19) driven by the turbine (13). The mechanical arrangement (19) couples the turbine (13) and the thermodynamic cooler (18) such that the thermodynamic cooler (18) is mechanically driven by the turbine (13).
