HEATER ELEMENT HAVING TARGETED DECREASING TEMPERATURE RESISTANCE CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO/2017/151965
Kind Code:
A8
Abstract:
A heater is provided that includes at least one resistive heating element having a material with a non-monotonic resistivity vs. temperature profile and exhibiting a negative dR/dT characteristic over a predetermined operating temperature range along the profile. The heater can include a plurality of circuits disposed in a fluid path to heat fluid flow.
