AI Technical Summary
In existing thermocouple calibration furnace air-cooling devices, the airflow from the fan is unevenly distributed, resulting in inconsistent cooling rates on the furnace surface, which may affect the structural stability of the furnace and shorten its service life.
The motor inside the housing drives the connecting rod to drive the fan and the spur gear. The gear uses a long toothed plate to mesh with the long gear, which drives the long toothed plate to slide back and forth. Combined with the L-shaped connecting frame, the airflow direction and range are adjusted to achieve uniform airflow coverage. It is also equipped with a rebound mechanism to prevent rigid impact and dust from entering.
This achieves uniform airflow distribution on the furnace surface, improves cooling effect and equipment stability, prevents localized thermal stress concentration, and extends the service life of the furnace.
