With Cooling Means Patents (Class 335/300)
  • Resin-empotted dry-type electromagnet for dusty and gassey locations
    Patent number: 4009459
    Abstract: An electromagnet is disclosed. The electromagnet has a winding that is wet wound with an epoxy material filled with grains of a material having a high coefficient of thermal-conductivity. The entire winding is empotted dry in a similar epoxy having grains of the said material. Fins are connected to the outside of the dry empotment for carrying away heat transferred to the fins from the coil.

  • Superconductive winding with cooling passages
    Patent number: 3956724
    Abstract: Individual wires in a winding are formed as polygons having contacting faces and noncontacting faces. Contacting faces of adjacent wires are positively engaged, while the noncontacting faces of adjacent wires form the periphery of openings that extend through the winding. Insulation may be removed from the noncontacting faces to facilitate cooling.
