Abstract
A positive temperature coefficient (PTC) heater apparatus is provided. The PTC heater apparatus includes a PTC heater, a resistance temperature detector (RTD) sensor mounted to the PTC heater and a controller logic unit electrically connected to the RTD sensor to receive readings of the RTD sensor, which, when the PTC heater is powered on, indicate whether the PTC heater is faulty.
Claims12
A positive temperature coefficient (PTC) heater apparatus, comprising:
- a PTC heater;
- a resistance temperature detector (RTD) sensor mounted to the PTC heater;
- and
- a controller logic unit electrically connected to the RTD sensor to receive readings of the RTD sensor, which, when the PTC heater is powered on, indicate whether the PTC heater is faulty,
- wherein the PTC heater comprises:
- dielectric layers;
- a first conducting trace comprising a first conducting trace portion interposed between the dielectric layers;
- a second conducting trace comprising a second conducting trace portion interposed between the dielectric layers;
- and
- PTC heating patches, each being electrically connected between the first and second conducting trace portions and interposed between the dielectric layers.
