Abstract
A downhole tool cooling device () is described, wherein a downhole tool () is thermally coupled to a rechargeable cold source () comprising a solid cold source body () being contained in an insulated cooling medium vessel (), and wherein the downhole tool () is thermally coupled to the cold source () by means of a cooling circuit () comprising a first heat exchanger () arranged at the downhole tool () and in a fluid communicating manner being interconnected with a second heat exchanger () arranged in the solid cold source body (), wherein a refrigeration system () is thermally coupled to the cold source () during a downhole operation of the cooling device (). Furthermore is described a method for cooling a downhole tool (). Also is described use of a pre-cooled solid cold source body () contained in an insulated cooling medium vessel () as a cold source () for a cooling circuit () being thermally coupled to a downhole tool () being in the need of cooling during downhole operations.
