MAGNETIC COIL SYSTEM COMPRISING A COIL SYSTEM AND A POSITIONING SYSTEM

摘要

The invention relates to a magnetic coil system for the contactless displacement of a magnetic body in a working volume (B). Said magnetic coil system comprises a navigation coil system which at least partially surrounds an inner area (A) containing the working volume (B), and several navigation coils (102). Said magnetic coil also comprises a positioning device for determining spatial coordinates of a magnetic body (201). Said positioning system comprises at least one emitting coil (301) that is disposed in the inner area (A) and a capturing device (302). Said magnetic coil further comprises a cooling system for cooling at least one additional navigation coil (3102) comprising several winding layers (304). Said cooling system comprises at least one first planar heat sink (307) that is in thermal contact on a large part of the surface with the navigation coil (102) and are formed respectively from cooling pipe parts (309) made of an electrically conductive material. When seen in the cross-section, the cooling pipe parts (309) form a plurality of cooling channels (312) that are arranged adjacent to each other. Said cooling pipe parts (309) are arranged on top of each other between the insulating means (310) for electric insulation. The first heat sink (307) comprising the navigation coil (102) is connected to the outer side that faces away from the inner area (A) or is arranged between two adjacent winding layers (304) of the navigation coil (102).
