Further, the correction mode of the included angle of the ventilating fan blade is rapidly determined by monitoring the sound outside the box body after the rotating speed of the fan reaches the critical rotating speed, so that the heat exchange efficiency is met, and the sound outside the box body is reduced.
Further, after the rotating speed of the fan reaches a critical value and the included angle of the air exchanging fan blades is adjusted, the rotating speed and the flow speed of the heat exchanging liquid are further adjusted according to the size of external sound, the rotating speed of the fan is reduced while the heat exchanging efficiency is ensured to be unchanged, and the flow speed of the heat exchanging liquid is increased so as to reduce sound generated by the operation of the fan at the critical rotating speed, so that the noise reduction effect is further improved.
Further, the invention can rapidly judge the heat dissipation mode aiming at heat dissipation in the box body by monitoring the temperature in the box body and external sound, thereby shortening the judging time and further increasing the heat dissipation speed; the temperature in the box body is compared with the preset standard, so that the corresponding adjusting mode of the corresponding operation parameters in the heat radiating unit is determined quickly, the heat radiating efficiency is ensured, and meanwhile, the operation safety of all parts in the heat radiating unit is ensured by adjusting all operation parameters, so that the service life is prolonged.
