PTC Heater Detailed
In the case of materials with higher thermal conductivity (such as aluminum, copper, graphite blocks, etc.) that conduct heat, the distance S between the heated solid and the PTC heater should be within 30mm; for materials with slightly larger thermal conductivity (such as : In the case of steel, stainless steel, titanium, thermally conductive ceramics, etc.) conduct heat, the distance between the heated solid and the PTC heater should be within 10mm; for materials with poor thermal conductivity (such as plastic, non-porous rubber, insulating paper, etc.) , Mica sheet, etc.) in the case of heat conduction, the distance between the heated solid and the PTC heater should be within 3mm; insulation materials (such as fiber paper, rubber, foam board, etc.) cannot be used to conduct heat. If the material with better thermal conductivity is used and the distance between the heated solid and the PTC heater is smaller, the heated solid will obtain a relatively stable temperature.
The ratio of the area of the heat dissipation structure to the heat transfer area of the PTC ceramic body should not exceed 3 times. If the proportion of the area of the heat dissipation structure is too large, the temperature obtained by the heated solid will be unstable.
