How does Dewalt 8″ bench top grinder get cooled when in use

I am curious as to how does my Dewalt 8″ Bench top Grinder get cooling air when in use, since I see no vent opening in the body and I find it gets very warm after 15-20 minutes of use, with light grinding and wire-brushing; is this normal?

Thanks.

You could add sun glasses and a smiley face to the grinder to make it look cool.

lol

I am pretty sure there is a hidden vent somewhere, I would also say they have finn’s inside the case to dispatch heat. I would also say that it will suck outside air in from around the shaft.
