The use of semiconductor refrigeration sheets in the circulating cooling chamber of the explosion-proof machine to cool the liquid provides a closed and safe system. This has the advantage that semiconductor refrigeration does not require the use of traditional refrigerants that may be flammable or harmful, which is a significant safety advantage for an explosion-proof environment. Since the semiconductor refrigerating sheets have no moving parts, they do not cause vibration nor noise during operation, do not generate sparks, and have high operational reliability, which is important for stable operation of the explosion-proof motor.
