The invention relates to a cooling device (20) for cooling a superconductor (5), wherein the cooling device (20) comprises a linear compressor (23) for compressing a working medium and a cooling unit (22) for providing a cooling power to a cryogenic coolant of the superconductor (5) by expanding the working medium, wherein the linear compressor (23) comprises two pistons (31) of which at least one, preferably both synchronously relative to each other, are displaceable at a frequency (f) and a stroke (H) linear to the other piston, wherein a defined cooling power can be generated at a good efficiency so that the cooling device (20) is suitable for use particularly in mobile installations, such as ships. To this end, according to the invention, the stroke of the at least one displaceable piston (31) is controlled at a preferably prescribed target value. |
