A gradient coil unit includes a primary coil, a secondary coil and a carrier unit. The carrier unit stabilizes the primary coil and the secondary coil, and is formed from an encapsulating material. The carrier unit may include at least two encapsulating pockets that each include a delimiting structure and a filling. A thermoset component unit includes an electronic component and a carrier unit surrounding the electronic component, and being formed from an encapsulating material. The carrier unit may include at least one encapsulating pocket that includes a delimiting structure having a first material, and a filling having a second material.

Gradient coil unit for a magnetic resonance device

A gradient coil having a coil body made from a cured casting compound and at least one cooler embedded in the casting compound, serving to conduct a fluid coolant, wherein the cooler and the casting compound do not adhere to each other.

Gradient coil and method for the production of a gradient coil

A cooling device for disposal between two flat coils of a gradient coil has at least one first and with at least one second foil that are connected to each other in areas such that continuous cooling channels for a cooling fluid are formed. The cooling channels are branched, whereby an improved cooling effect is produced with a smaller thickness of the cooling device.

In a gradient coil and a method to manufacture a gradient coil for a magnetic resonance apparatus, the gradient coil has at least one saddle coil, the saddle coil having a spatially shaped, electrically conductive plate with a line-shaped recess penetrating the plate. Conductor structures that create a gradient magnetic field in an examination region when a current signal flows therethrough are formed by the recess and by the shaping of the plate. The recess is filled with an electrically insulating material before implementation of the spatial shaping.
