120W LED cooling module 4
- Name：120W LED cooling module 4
- Category：120W LED cooling module 4
- Product Description
How it works:
PTC heater for heating material is a semiconductor material, barium titanate-based, mixed with trace rare earth elements at high temperatures around the knot is made, PTC element resistance - temperature characteristics shown in the figure, TC called theCurie point point, the point is the heating element of the operating point, at room temperature and the Curie points, PTC element resistance value is small. Resistance with increasing temperature and decreases slowly, the current increases, the temperaturegradually increased, after the temperature when the temperature rose to TC, PTC showed a positive temperature coefficient, theresistance increases rapidly with increasing temperature, work current dropped significantly, so that the temperature back to TCpoint, when the temperature drops further, PTC element values dropped significantly negative, significant increase in operating current, operating temperature will rise to TC double points, we can see, PTC heating element with automatic temperaturecharacteristics, heat power is not with the ambient temperature, voltage fluctuations.
Features:
PTC heater as a heat source, has the following advantages:
Safe, no fire, automatic constant temperature, the outer surface of double insulation.
Save energy, thermal conversion efficiency, rapid heating.
Long service life, aging resistance, resistance to corrosion.
