Temperature-control device for controlling the temperature of a fluid and a method for controlling the temperature of a fluid

A temperature-control device for controlling the temperature of a fluid comprising:

• a coil arrangement comprising a first coil and a second coil,
• wherein the first coil extends from a first base surface to a second base surface, and the second coil extends from a third base surface to a fourth base surface, wherein
• the first base and the third base are coaxially aligned and spaced apart so that a first magnetic field can be generated within a first magnetic field extending region between the first base of the and the third base by means of the first coil and the second coil and
• the second base surface and the fourth base surface are coaxially aligned with each other and spaced apart so that a second magnetic field can be generated within a second magnetic field extending region between the second base surface and the fourth base surface by means of the first coil and the second coil;
• a magnetocaloric component which is attached so as to be movable relative to the coil arrangement that the magnetocaloric component and the coil arrangement can be moved relative to each other along a direction at an angle to the coaxial direction into the first and/or second magnetic field extending region and out of the first and/or second magnetic field extending region for generating a magnetocaloric temperature-control of the magnetocaloric component based on a magnetic field change during relative movement of the coil arrangement with respect to the magnetocaloric component;
• and
• a heat transfer system thermally contacting the magnetocaloric component for providing heat transfer towards and/or away from the magnetocaloric component.

A method for liquifying, the method comprising:

• generating a magnetic field within a first magnetic field extending region between a first coil and a second coil that is based on the first coil and the second coil and within a second magnetic field extending region between the second coil and a third coil that is based on the second coil and the third coil, wherein the first coil, second coil, and third coil are arranged in a row along a coaxial direction and are aligned therealong and are spaced apart from each other to form a coil arrangement;
• generating a respective magnetocaloric temperature-control of a first magnetocaloric component and a second magnetocaloric component based on a magnetic field change by relative movement of the coil arrangement with respect to the first and second magnetocaloric components, wherein the first magnetocaloric component is movable relative to the coil arrangement along a direction at an angle to the coaxial direction into the first magnetic field extending region and out of the first magnetic field extending region, and wherein the second magnetocaloric component is movable relative to the coil arrangement along the direction into and out of the second magnetic field extending region;
• transferring heat toward and/or away from the first and second magnetocaloric components via a heat transfer system that thermally contacts each of the first and second magnetocaloric components.
