[0036] Example 2

[0037] Please refer to Figure 1 and Figure 2 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0038] An exhaust fan 5 is fixed to the inner wall of the placement hole 104; a spoiler 103 is fixed to the inner wall of the heat exchange chamber 102, and there are multiple spoilers 103, which are evenly arranged on the inner wall of the heat exchange chamber 102; the double-cooling closed cooling tower is provided with multiple spoilers 103, so that the outside air is turbulent in the heat exchange chamber 102, which can not only increase the contact area between the surface of the radiator or the heat dissipation device and the air, accelerate the heat transfer speed, thereby improving the heat dissipation efficiency, but also help reduce thermal resistance, that is, reduce the resistance of heat in the transmission process, so that the heat is transferred from the radiator or the heat dissipation device to the air faster; at the same time, through the air turbulence design, the accumulation of hot spots on the surface of the radiator or the heat dissipation device can be effectively reduced, and excessive heat concentration can be avoided to cause local overheating.

[0039] When the utility model is used: firstly, the device is placed in a suitable position, then the device is electrically connected to an external power source, then the staff injects the coolant into the liquid storage tank 101, and installs the exhaust fan 5 in the placement hole 104, and at the same time, the filter plate 3 is installed on the top of the tower body 1 through the fixing component 4.

[0040] When the heat exchange tube 2 needs to be cooled by heat exchange, the staff only needs to control the operation of the water pump 601 through the external control device.

The staff can turn the knob 402 to drive the rotating shaft 401 to rotate, and the rotating shaft 401 drives the threaded tube 403 to move, thereby driving the block 404 fixed at one end of the threaded tube 403 to move synchronously.
