Why do some air coolers have air intake covers while others don’t?

①Some air coolers have air intake covers, while others don’t? ②And a book states that if an air shroud is installed on the reactor effluent air cooler, it should be able to provide 50% of the normal cooling capacity when the fan is shut down. Why is this? Are there any relevant materials?
Does no one know? :'(
What component on a fan does the intake shroud refer to? I don’t quite understand.
It’s just that a cover is added on top, and the middle part of the cover is cylindrical, like a chimney
Having an air intake cover is a good design； None. This indicates that the imitation is inadequate – there is a lack of understanding of fluid dynamics and of the function of air intakes.
What is the purpose of that design?
Guidance； Protect the outlet from the effects of tangential wind
1. The air intake cover serves to 1) direct the airflow, thereby ensuring uniformity of the gas medium during the heat exchange process and improving the efficiency of heat transfer; 2) when the fan stops operating, hot air rises while cold air flows in from below the air intake cover to carry out heat exchange. The air intake cover can prevent the mixing of cold and hot air. 3. Does air cooling without an air intake cover have cooling water pipes installed at the top?
The ventilation methods for air coolers include induced draft, forced draft, and natural ventilation. Due to the suction effect of the air duct, the induced draft type can maintain 30% of its cooling capacity even when the fan is shut down.
Do you have any specific information? But that air intake cover isn’t very tall; is the suction force strong?
No, we usually use blow-type ones.
