Working principle of circulating water cooling device for vacuum unit

Pump the water in the storage tank into the water sprayer, and pump the water to the cooling water inlet of the unit 

Under the action of exhaust fan, the water evaporates on the surface, dissipates heat and cools down, and then returns to the water storage tank. The distribution of the holes on the porous plate determines the position of the water column, so that the small holes on the porous plate are evenly distributed, so that the air flow can fully contact the water column and form the surface of swallow hair as large as possible Achieve the purpose of water cooling 

Considering that the water discharged from the vacuum unit is far away from the air and the temperature difference between it and the air is relatively large, the first stage of forced cooling with air cooling is designed. The water discharged from the vacuum unit passes through the radiator first, and the radiator is placed behind the fan, and then the cool air passing through the water is blown to the radiator, so that the hot water discharged from the diffusion pump is cooled, and then returned to the water storage tank. The cooling water flow in the diffusion pump can be controlled It was observed directly in the device.
