Specifically, the heat pipe 21 is made of any one of copper, aluminum, carbon steel, stainless steel, and alloy steel, and the preferred material is copper.
Alternatively, the cross-sectional shape of the heat pipe 21 is one of circular, square, oval, and equilateral polygon, wherein circular is a preferred cross-sectional shape, and the heat pipe 21 may also be in a bellows shape.
Each heat pipe 21 is provided with a heated end 211 and a cooled end 212, the cooled end 212 extends into the water tank 1, the heated end 211 is connected with the electric heating device 22, and the electric heating device 22 can transfer heat energy to the heat pipe 21 but cannot transfer electric energy to the heat pipe 21. The heated end 211 rapidly transfers the heat generated by the electric heating device 22 to the cooled end 212, and the cooled end 212 is cooled by the water in the water tank to form energy conversion.
Specifically, the electric heating device 22 includes an electric heating box 221 and an electric heating tube 222 disposed in the electric heating box 221, and the heated end 211 of each heat pipe 21 is disposed in the electric heating box 221.
