Dead gnats

Live in an apartment and past few days lots of dead gnats are blowing in from my swamp cooler in living room esp in the evening? Why and do I do?

Most likely these are fungus gnats. They live on debris that over time collects in your cooler and any duct work. Not sure what a "swamp cooler" is exactly. If it is a pad and fan system using a fiber mat for cooling, check all those areas for dirt and debris as well.
