In this embodiment, the number of the air inlets 15 is two, and the air inlets 15 are symmetrically arranged, but the number of the air inlets 15 is not limited to two, and a larger number of the air inlets 15 may be provided as required.

The liquid outlet of the water tank 2 is communicated with the liquid inlet of the water pump 17 through a second pipeline, and the liquid inlet of the water tank 2 is communicated with the liquid outlet of the water pan 5 through a third pipeline. The water tank 2 is used for storing and collecting water captured by the net 7, the water tank 2 is positioned outside the shell, the water tank 2 is arranged on the upper portion of the side wall, the height of the water tank 2 is lower than that of the water receiving tray 5 and higher than that of the spraying pipe 13, the purpose of the arrangement is that on one hand, water collected by the water receiving tray 5 can automatically flow into the water tank 2 for storage, and when the liquid level reaches the preset water level of the water level monitoring device 1, the second electric valve 21 is opened, the first electric valve 16 is closed, and water in the water tank 2 can be sprayed through the spraying pipe 13; on the other hand, the water does not have better gravitational potential energy due to the power consumption of the fan 3, namely the water does not need to be pumped to the height of the spray pipe 13 again from the bottom of the shell through the water pump 17. In addition, in order not to affect the use of the original evaporative condenser, the water tank 2 is preferably disposed outside the housing. A flow meter 26 is arranged on the third pipeline, the flow meter 26 is used for detecting whether the water is collected by the collecting net 7, if the water is detected to be collected by the collecting net 7 in the starting time, the flow meter 26 feeds back an electric signal to the controller 20, and the controller 20 controls the ion generator 4 to continue to work.

In this embodiment, the ion releasing end 6 and the collecting net 7 are oppositely arranged in the horizontal section, the ion releasing end 6 is located between the collecting net 7 and the fan 3, the ion releasing end 6 is used for releasing ions into the air, so that the water mist in the air is charged and captured by the collecting net 7, and in order to release the ions efficiently, the ion releasing end 6 is preferably of a tip emission structure. The electric ions released from the electric ion releasing end 6 are easy to be attached to the water mist in the air, so that the water mist is electrified and can move to the nearest object which is most easily conductive, and the electric ion wind is generated. In the present embodiment, the wind direction of the ion wind is opposite to the wind direction of the exhaust channel, because the ion releasing end 6 is disposed on the side of the collecting net 7 close to the fan 3, the water mist in the exhaust air can be fully collected, but the arrangement of the ion wind in the same direction (the ion releasing end 6 is disposed on the side of the collecting net 7 away from the fan 3) should also be within the protection scope of this patent. The collecting net 7 is chosen to have a net structure in order to minimize wind resistance and to better collect the mist droplets of charged ions in the exhaust air, the collecting net 7 should be chosen to be a material with good electrical conductivity, and other porous materials are within the scope of the present patent.
Further, in order to improve safety, it is necessary to electrically connect the collection grid 7 and the housing of the fan 3 to the ground port 9 through the ground line 8, so that the ions emitted from the ion generator 4 can be finally guided to the ground.
The electric ions emitted by the high-voltage ion emitter are captured by water mist drops in the air, so that the water mist drops towards the collection net 7 and are collected to generate ion wind, and the water collected on the collection net 7 is finally recycled due to gravity flow, so that the purpose of saving water is achieved, and the water mist is prevented from corroding shells of the fan 3 and the condenser 14.

The mode does not need to change the structure of the upper air outlet of the traditional evaporative cooling device, and can directly recycle the water in the saturated air, thereby reducing the production cost. In addition, in the embodiment, the first electric valve 16, the second electric valve 21, the water receiving tray 5, the water tank 2 and the water level monitoring device 1 are eliminated, so that the structure of the evaporative condenser 14 is simplified, and the production cost is reduced.

At the moment, the controller 20 continuously controls the ion generator 4 to work for a preset time, the ion generator 4 generates a high-voltage electrostatic field, then the electric ions are released into the air through the electric ion release end 6, after the electric ions are captured by water mist drops in the nearby air, the charged water mist directionally moves to the nearby collection net 7 to be collected, finally enough accumulated liquid water flows down due to gravity, is collected in the water receiving tray 5, and finally flows to the external water tank 2 to be recycled. If the flow meter 26 detects that the water mist in the air is not captured by the collection net 7, the water level detection means detects the water level in the water tank 2. If the water tank 2 and the water level monitoring device 1 are not provided, the step of detecting the water level in the water tank 2 is not performed.

If the water level in the water tank 2 is lower than the predetermined level, the second electric valve 21 is closed, and the first electric valve 16 is opened.
If the water level in the water tank 2 is lower than the predetermined level, that is, the water in the water tank 2 is less, the controller 20 controls the second electric valve 21 to close and controls the first electric valve 16 to open, and the water pump 17 uses the water at the bottom of the housing.
