Patent ID: 7732950

Claim:
A radiator used for a linear mobile motor comprising a field pole having a plurality of permanent magnets with different magnetic poles arranged alternately along a field yoke, and an armature arranged opposite to the field pole via a magnetic gap and formed by winding a single or a plurality of coils around a core, the field pole being used as a stator and the armature being used as a mover that is moved along a longitudinal direction of the stator, the radiator comprising: a heat absorbing unit constituted by a first portion of a thin plate heat pipe having therein thin holes containing working fluid for allowing the working fluid to move therethrough, wherein the thin plate heat pipe is bent in conformity with a shape of the coil or coils such that the heat absorbing unit is in close contact with a surface of the coil or coils, and the radiator further comprising a heat radiating unit constituted by a second portion of the thin plate heat pipe, the heat radiating unit projecting away from the magnetic gap, the thin plate heat pipe having closed first and second ends such that the working fluid is retained within the thin plate heat pipe, wherein the thin plate heat pipe has a flat plate-like frame having a thickness less than a width and a length, and having at least one conduit positioned within the frame to retain the working fluid, and wherein the thin plate heat pipe is fixedly connected to the armature such that the thin plate heat pipe, including the heat absorbing unit and the heat radiating unit, is configured to move with the armature.
