Both air cooled and water cooled machine guns have been made.
They were called dogfights.
Speaking on a general level: WWI was the war of the 'big guns' and the machine guns, WW II of the tanks and air power.
During WW2 aircraft used machine guns and automatic cannons, 20mm primarily. During the Vietnam War, jet aircraft used 20/30mm cannons and air to air missiles during aerial combat (dog-fights).

The machine gun evolved from the Gattling gun, a device that that rapidly fired bullets when cranked. WWI saw the first true machine guns, liquid and air cooled. http://en.wikipedia.org/wiki/Gatling_gun Another example is the french Mitralleuse, used in the Franco/Prussian war of 1870/71.
Early machine guns such as Maxim and Vickers were water cooled and had distinctive jackets around their barrels, except models intended for installation on airplanes. Most later machine guns are air cooled to make them lighter and more portable.

The combat in the air gained bombs and machine guns on the planes.

The following machines produces cool air: Cool air fan/machine, air conditioner, ACM - Air cycle machines, Neopstar Air Cooler, Salveo, to name a few. Prices start from â£35.
Dew is the water that has condensed on a cool surface overnight from water vapor in the air.
A chiller is a machine that is used to remove heat from a liquid through a vapor-compression or absorption refrigeration cycle. It is commonly used in air conditioning systems and industrial processes to cool down equipment or spaces.
Yes, they did throw babies up in the air and shoot them with machine guns like a target.
