    • 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).
    • 对于磁性体的工作体积(B)的非接触式运动磁铁线圈系统。 磁线圈系统包括至少部分地包围的内部空间中,包含工作体积(B)(A)和包括多个导航线圈(102)的导航线圈系统。 此外,磁体线圈系统包括用于确定磁性体(201)的空间坐标的定位系统。 该定位系统包括至少一个在内部(A)布置在所述发射器线圈(301)和接收装置(302)。 此外,磁体线圈系统用于冷却多个绕组层(304),其具有线圈导航(102)中的至少一个的冷却系统。 所述冷却系统包括至少一个第一平面的散热器(307),其是使用在热接触导航线圈(102)和每个冷却管道部件的(309)的大面积的导电材料形成。 在横截面中看到的那样,冷却管部(309)形成多个相邻布置的冷却通道(312)的。 用于冷却管道部件(309)彼此电绝缘的绝缘装置(310)之间。 第一散热器(307)被连接到导航线圈(102),面向远离所述内部空间(A)的外部或导航线圈(102)的两个相邻绕组层(304)布置之间。
