[0041] A cooling component, the cooling component includes a fixing frame 21, a water reservoir 22, and a mounting plate 23;

[0042] The fixing frame 21 is fixed on the upper surface of the ground 11, the water reservoir 22 is fixed on the upper surface of the ground 11, and the mounting plate 23 is fixedly mounted on one end of the outer surface of the fixing frame 21;
