I have a couple of ideas. I was wondering if the following would be legal.
1) An onboard tank with some kind of cold liquid circulating through tubing wrapped around the motors. And/or a fan blowing across the tubes making a cold wind on the breakers.
2)An onboard can of cold spray actuated by a servo.
Sorry, BOTH are illegal due to using materials not on the Additional Hardware List (AHL). Remember, All
the robot must
be either from the kit or the Additional Hardware List (AHL). Cold spray is not on the AHL, and you have no AHL legal refrigerant to circulate. You can use cold spray as a TOOL, but not as a PART on the robot. BTW, I already joked about that before. See above.
Hey, how about clamping a thermal mass (made out of AHL stuff) onto each breaker and chilling THEM before each round?
--- Air supply expansion as a coolant? ---
Depending on the pneumatics manual rules, you MIGHT be able to create an expansion valve for 120psi air and a heat fin assy to create a pretty lousy
cooler out of the compressed air supply... Gad, that "feels" AWFULLY expensive in terms of compressor power usage for a TINY bit of cooling.
Are there any Air Conditioning experts out there that can run the numbers for that one and comment on it? How much cooling can you get by expanding the 120 PSI air supply to atmosphere for two minutes?? Assume you have NO other cylinder loads, have precharged ALL the tanks in this setup before the round, and clamped the heatsink onto ONE breaker:
(compressor)--> (ALL tanks)--> (control valve)--> (expansion_valve & heatsink assy)--> open air
At round start you open the control valve, and run the compressor full tilt. How much cooling could we get, in terms of degrees dropped on that one breaker over the two minutes?
That aside, I'm more interested in seeing DESIGN METHODS to prevent breaker trips listed here, versus simply finding ways to FOOL the breakers with chilling. Anyone have any OTHER ways to prevent breaker trips other than chilling, and the design methods already listed?
