The invention discloses an electric reactor convenient to dissipate heat and a method for dissipating heat of an electric reactor; the electric reactor comprises a water tank, a
threaded rod and a second motor, an electric reactor body is installed above the water tank, a top frame is connected to the upper portion of the electric reactor body, the electric reactor body is wrapped with a circulating
water pipe, the upper end of the circulating
water pipe is connected with a first diverter, the electric reactor body is installed at the other end of a second connecting
pipe, a water pump is arranged on the second connecting
pipe, a gear is arranged on a transmission shaft, the
tooth surface of the gear is meshed with a rack, and a first motor is connected to an
impeller. According to the electric reactor convenient to dissipate heat and the method for dissipating heat of an electric reactor, water in a water tank is pumped into the circulating
water pipe through the water pump for heat exchange, then
cold air is blown into the air holes through the heat dissipation fan to cool the water in the water tank, in this way,
water cooling of the device can be achieved, and dust is prevented from entering through a protective shell; and dust entering is reduced, so that the heat dissipation performance of the device after long-time use can be stable.
