[0031] Through the action of the composite serpentine curved pipe 31, the coolant can be located in the inner cavity of the cooling box 3.

[0037] Through the action of the shock absorber 518, the fixing frame 513 and the fixing plate 511 can be damped, so that the parts below the fixing frame 513 can be damped during use, thereby ensuring the overall stability of the coolant cooling device.

[0038] The front and rear parts of the lower surface of the right part of the fixed plate 511 are fixedly connected with sliders 514, and the two sliders 514 are respectively located at the front and rear sides of the protective cover 512, and the outer walls of the two sliders 514 are respectively movably connected with the inner cavities of the front and rear parts of the upper part of the fixed frame 513, and the inner walls of the front and rear sides of the two sliders 514 are slidably connected with slide rails 517, and the sides of the four slide rails 517 away from the two sliders 514 are respectively fixedly connected with the inner cavity of the fixed frame 513, and the tops of the inner cavities of the two sliders 514 are fixedly connected with springs 516, and the lower surfaces of the two springs 516 are respectively fixedly connected with the bottom of the inner cavity of the fixed frame 513;
