[0026] In order to improve the air circulation efficiency and accelerate the heat dissipation rate of cooling water, a functional component for accelerating the air circulation rate is provided outside the heat dissipation component;

[0027] like Figure 4 and 5 As shown, the functional component includes a fixed shaft 2 and a linkage shaft 3, the linkage shaft 3 is arranged on the front side of the fixed shaft 2, the rear end of the linkage shaft 3 is movably connected to the front side of the cooling water tank 4 through a bearing, a plurality of blades 5 are installed on the outside of the linkage shaft 3, both ends of the fixed shaft 2 are movably connected to the inner wall of the cooling water tank 4 through bearings, a plurality of stirring blades 6 are installed on the outside of the fixed shaft 2, the rear end of the linkage shaft 3 penetrates the cooling water tank 4 and is fixed to the front end of the fixed shaft 2; a spiral tube 7 is sleeved on the outside of the front end of the linkage shaft 3, a plurality of blades 5 are arranged inside the spiral tube 7, and the rear end of the spiral tube 7 is fixedly connected to the front side of the cooling water tank 4.

Through the connection between the output shaft of the motor 12 and the fixed shaft 2, the motor 12 can drive the stirring blade 6 on the fixed shaft 2 and the fan blade 5 on the linkage shaft 3 to rotate. A mounting bracket 13 is installed on the rear side of the motor 12, and the end of the mounting bracket 13 away from the motor 12 is fixed to the rear side of the cooling water tank 4.

The rotation of the stirring blades 6 can improve the flow efficiency of the cooling water, avoid heat accumulation and ineffective heat dissipation, thereby ensuring the heat dissipation effect of the utility model.
