The heat generated will be absorbed by the circulating water cooling pipeline 12 and discharged through the refrigerant, and the noise will be absorbed and isolated inside under the action of the sound-absorbing protective shell 10. At the same time, when the equipment is running, the rotor connecting rod 4 will drive the electromagnetic rotor to rotate, and the electromagnetic rotor drives the cooling fan and the magnetic water pump in the first support block 1 to rotate to circulate and dissipate heat to the water connected to the circulating water tank. Moreover, since the speed of the cooling fan and the magnetic water pump driven by the magnetic rotor is different from that of the rotor connecting rod 4, it is determined by the input power.
