Gradient coil with direct cooling

摘要

Gradient coil for magnetic resonance (MR) devices has direct cooling by means of cooling lines that are embedded in the coil and through which a cooling agent flows. The cooling lines are arranged substantially parallel to one another, such as parallel to the axis of the gradient coil, and are combined to form heat exchanger modules whose individual cooling lines are coupled with one another so that the maximum length between the inlet and outlet of a module corresponds to twice the longitudinal length of the gradient coil.
