Immersion heating element with highly thermally conductive polymeric coating

摘要: Electrical resistance heating elements are provided which useful in fluid mediums, such as air and water. The include an element body having a supporting surface wire wound onto the is connected to pair of terminal end portions. Disposed over wire, most surface, thermally-conductive polymeric coating hermetically encapsulates electrically insulates from fluids be heated. This polymer has thermal conductivity value at least about 0.5 W/m °K. Improved properties preferably by ceramic powder, Al 2 O 3 MgO, glass fiber additives.
