Heating principle of ceramic infrared heater
The purpose of infrared heating is to convert electrical energy into infrared radiant energy output, creating an efficient heating conversion mode to efficiently heat the target material.
Definition of heat energy: heat energy is the energy produced by temperature difference, which flows from a place with high temperature to a place with low temperature.
Thermal conversion method
When the current flows through the resistance wire of the heater, heat energy will be generated, and the thermal power can be calculated by I2/R or U2/R.
1. Through the solid medium to the heated object
2. Transfer through gas/liquid to heated object
3. Direct radiation to the heated object
In atmospheric environment, the radiator heat transfer mode is convection and radiation
In the vacuum environment, the radiator heat transfer mode is radiation
MAIN PRODUCT
Method Of Heat Transfer
1. Choose a source with high emissivity
At the same temperature: only the heat source with high radiation coefficient can produce high radiation capacity;
Heat source in the same material: temperature is proportional to the fourth power of radiation capacity.
2. At the same temperature: only the heat source with high radiation coefficient can produce high radiation capacity;
Heat source in the same material: temperature is proportional to the fourth power of radiation capacity.
3. Radiators filled with insulation minimize heat loss on the back
4. Make the band of the radiator correspond to the infrared absorption characteristic curve of the target material, and the Absorptivity of Paper, Oil Paint, Black Ceramic, Copper, Iron, Aluminium
5. Minimize air humidity to maximize radiation transfer
Because water has a better absorption rate of infrared ray, it reduces the humidity of the air, you can reduce the loss of infrared ray
6. Minimize air humidity to maximize radiation transfer
7. Make the radiator's thermal response curve conform to the requirements of each process
