What are the advantages of thick film heaters?
The thick film heater heating element is mainly composed of a stainless steel tube substrate, an inner insulating dielectric layer, a resistance heating layer and an outer insulating dielectric layer from the inside to the outside, and the water flow flows through the stainless steel tube, wherein the inner insulating medium layer has a thickness of about 100 micrometers. Since the heat conduction distance from the resistance heat generating layer to the stainless steel substrate is short, the thermal resistance is small and the thermal response speed is fast. Among them, the thick film heating tube, the barrel structure, the natural water channel, the 360 degree integral channel heating, the overall heating is relatively uniform, and the heating efficiency is not reduced due to the generation of a large number of bubbles on the heater surface. Since the heat can be conducted in time, the surface temperature of the entire heating tube is not high and does not cause an open flame. Good safety and long service life.
