Power saving method for reflow welding

The reflow furnace is the equipment with the largest power consumption in SMT. After expert testing, the energy consumption of the existing reflow furnace for work (heating PCB) is not very high, not exceeding 40% of the total energy consumption; Where did the other 60% go? The main energy consumption is analyzed as follows:
1--> Body absorbs heat energy.

2--> Shell radiates heat.

3--> Heat energy taken away by cooling zone and exhaust gas.

4--> Power consumption of reflux fan, transmission network chain and control system.

5--> The heat convection imbalance in the temperature zone causes the heat lost from the inlet or outlet of the plate.

Energy-saving technologies for reflow furnaces include:
1. Use high temperature resistant ceramic fiber cotton to strengthen heat insulation of furnace.
2. Adjust the airflow balance according to the temperature difference in the temperature zone.
3. Install the energy-saving control system to automatically adjust the operating parameters according to the predetermined time of multiple stages during standby.
4. Install a speed regulating device to control the speed of the reflux fan, and automatically adjust the speed for about 10 minutes on standby. The running speed of the motor will be reduced or stopped according to the actual situation, which will minimize the consumption and improve the power factor of the motor.
5. Install the electric air valve to automatically control the opening and closing according to the working condition.
