Detailed Description
A water cooler for cooling the motor of water-jet propulsion unit features that the submersible motor 2 is used as its motor, the electrochemical corrosion-preventing material is coated on its external surface, a wireless temp sensor 3 is installed in the motor 2, a sealed water tank 4 is installed outside the submersible motor 2, and the drive shaft is extended out of the sealed water tank and is not in contact with it. The sealing water tank is made of stainless steel and welded on a supporting plate 5 welded on a ship plate. A water inlet pipe 7 is added between the lower side of the nozzle and the upper part of the side edge of the water tank 4, and water is filled in the water inlet pipe through a valve 8. A water outlet pipe 10 is connected between the sealed water tank 4 and the bottom of the ship, and a valve 11 is also arranged in the middle of the water outlet pipe to control water. The wireless temperature sensor 3 determines the opening and closing of the two valves 8 and 11 of the pipeline.
