Abstract: Examples described herein relate to adiabatic cooling units. For example, a method for mixing gases within an adiabatic cooling unit includes allowing a first gas at a first temperature to enter a mixing chamber on a non-exposed side of an adiabatic cooling media and utilizing a first baffle to direct the first gas in a direction away from the adiabatic cooling media. The method includes allowing a second gas at a second temperature to enter the mixing chamber on an exposed side of the adiabatic cooling media and allowing the first gas and the second gas to mix in the mixing chamber creating a mixed gas. The method also includes creating an inlet with the first baffle and a second baffle to direct the mixed gas away from the adiabatic cooling media and allowing the mixed gas to enter through the exposed side of the adiabatic cooling media.
