NOVELTY - High temperature composite aluminum base heater comprises aluminum alloy substrate (101), inner insulating coating (102), resistance coating (103), conductor coating (104) and outer insulation coating (105). The high temperature composite aluminum base heater comprises aluminum alloy substrate. The inner insulating coating is printed on aluminum alloy substrate. The inner insulating coating is printed with resistance coating on the wall away from aluminum alloy substrate. The wall surface of resistance coating away from inner insulation coating is printed with conductor coating. The wall surface of resistance coating away from inner insulation coating and wall surface of conductor coating away from resistance coating are printed with outer insulation coating. USE - High temperature composite aluminum base heater. ADVANTAGE - The heater has functions of long-term working temperature not greater than 200 degrees C, breakdown voltage of insulating coating not greater than 1500 volts alternating current (VAC), heating power of resistance coating not greater than 20 Watts/cm2, low heat capacity, excellent heat conduction and better heat conversion efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of high temperature composite aluminum base heater.
