The device is not damaged, the influence of external environmental factors on the deaerator is reduced, and its service life is increased. Under the induction of the temperature sensor 12, when the temperature inside the protection box 1 is too high, the cooling fans 14 embedded on both sides of the middle part of the protection box 1 will be started to accelerate the air flow and reduce the temperature inside the protection box 1.
