I am working on a machine which has an upper side which processes a product. On the lower side of the machine there are a couple of motors with built in inverters and there is a laser unit. There are two fans which blow air out of the machine they sit opposite each other. The motors are mounted between them. Air can come into the machine from the bottom sides.
My question is this. Wouldn't it be much better to have one fan take air in from outside and another being used for extraction?
I think the present system will just cause the machine to draw up air from the bottom and straight out the fan without cooling the air around the unit. Am I right about that?
