That makes sense because when you compress gasses (and solids/liquids), each molecule has heat. When there are a ton of molecules in one place, the heat adds up until it is unbelievably high. Entropy takes away most of the heat via the heat sink. However, active cooling is something that can just almost always aid in passive cooling! The motor will typically be a quite efficient one that shouldn't get too hot. The problems start occurring when the motor is so close to the piston that the heat is moved to the [cooler] motor because of entropy. This is similar to what happens in the air conditioner. The gas is compressed, taking away the heat. that way, in the condensor, it is decompressed, leaving you with supercooled gas to cool the air using!
Sometimes, it takes years to gain respect and to learn to understand the opportunities that avail themselves to those who pay attention, are willing to learn from the best, and dig deeper into understanding what it means to be a competitive FRC team. - JaneYoung [more]
