what are heat pipes? are you guys just referring to the 8 pipes on the esc?

what about this? i thought if i could find some kind of little pump i could mount a small nitro tank on the chassis with some coolant/water in it and use fuel line to pump through the esc pipes and back into the nitro tank. i just dont know where i would find a tiny pump like that. i am just gonnna stick with the fan but this would be kinda cool.
