The thermal fuse activation assembly further includes a heat sink is thermally coupled to the thermal fuse.
Claims20
A thermal fuse activation assembly for a clutch comprising:
- a thermal fuse including a body containing a temperature sensitive member configured to activate upon a predetermined temperature;
- and
- a heat sink thermally coupled to the thermal fuse.
A coil assembly of a clutch comprising:
- a coil configured to selectively receive electrical current to cause the clutch to operate a compressor;
- and
- a thermal fuse activation assembly disposed in an outer facing surface of the coil assembly, the thermal fuse activation assembly including a thermal fuse in electrical communication with the coil and a heat sink thermally coupled to the thermal fuse.
A clutch assembly for a compressor comprising:
- a clutch disc operably coupled to the compressor;
- a pulley selectively engaging the clutch disc to drive the compressor;
- a coil assembly including a coil housing and a potting material, the coil housing receiving an electromagnetic coil configured to selectively engage the pulley to the clutch disc, the potting material formed about the coil and forming a portion of an outer facing surface of the coil assembly, the outer facing surface facing the clutch disc and the pulley;
- and
- a thermal fuse activation assembly formed in the outer facing surface of the coil assembly, the thermal fuse activation assembly including a thermal fuse in electrical communication with the coil and a heat sink thermally coupled to the thermal fuse, a portion of the heat sink exposed from the coil assembly.
