If this equipment is used, the air-cooling fan is directly installed on the top of the furnace, and the internal hot air and external cold air are circulated. The internal temperature of the furnace is adjusted by adjusting the fan speed, and the cooling airflow is directly blown onto the lamp tube, which can better cool the lamp tube to prevent the temperature from being too high, and has less impact on the heated parts.
