What are these for?

Pretty basic Q; what are these metal flaps that sit on the outside of the squirl cage of the swamp cooler? Any purpose for these here? Thanx

There is no picture so we can't see the flaps your talking about. Do the flaps open/close? Are there to guide the air into or out of the blower?
