A slider is movably installed on one side of the outer wall of the limiting rod. Connecting covers are arranged on both outer walls of the fan body.

[0006] When using a fixing component for a cooling tower fan in this technical solution, the staff makes the fan body stable inside the ventilation pipe through an external hoisting device, and connects the ventilation pipe, the support frame and the fan body through bolts. The elastic force of the spring pushes the heat conduction pad into contact with the outer wall of the fan body. An external liquid pump drives the coolant to flow through the connecting pipe into the connecting cover, so that the coolant circulates inside the connecting cover, and the temperature of the fan body is adjusted through the heat conduction pad.

[0007] Preferably, fixing plates are installed on both outer walls of the support frame. The fixing plates are respectively in contact with the inner wall of the ventilation pipe and the outer wall of the fan body. Bolts are arranged inside the fixing plates.

[0008] Preferably, an impeller is arranged on the outer wall of the lower end of the fan body. The impeller is located below the support frame. The fan body drives the impeller to rotate in a circular motion, thereby driving the air flow inside the ventilation pipe.

[0009] Preferably, the connecting cover is designed in a circular arc shape and is hollow inside. There is coolant flowing inside the connecting cover.

[0010] Preferably, connecting pipes are inserted and installed on the outer walls on both sides of the connecting cover, and the connecting pipes communicate with the inside of the connecting cover. The connecting pipes are connected to an external liquid pump, and the liquid pump transports coolant to the inside of the connecting cover through the connecting pipes.

[0011] Preferably, a heat-conducting pad is fixedly attached to the outer wall of one side of the connecting cover, and the heat-conducting pad is in contact with the outer wall of the fan body.
