Starting to try and work on a passive aero cooling project.
I have other ideas for active cooling utilizing thermoelectric systems.
But since aero is cheaper I’m going to take a crack at it. The only problem is it only works while in motion.
I started by designing the reacher intake port last night, trying to whip up a design that I could 3d print and just slide onto the part of the motor perpendicular to the face of the motor.
Definitely needs improvement but it’s the start.
I was having. But of trouble figuring out how to actually effectively design the intake system as im not as savvy with solid works as id like to be. But id definitely like to increase the intake area to multiply the volume of an air being shoved through the air channel. Kind of like this
The other ideas 4 active cooling consisted a utilizing a TEC module or Peltier module, or some sort of high efficiency cooling plate that sits in a pocket of this motor spacer. The motor spacer would have to be a two piece design to allow for a cavity to properly handle the module.
but reading more about it I think they are way to inefficient to actually implement into a design.
It would look something like this.
But I’d definitely have to make my own to get such an odd shape. To wrap around the bolt pattern.
The other idea to effectively attack the problem twice which would probably be most effective. Would be a two piece split design plate (hollowed out) this Allows radiator fluid pass through.
Using the inlets & outlets for cycling fluid through.
Id have to figure out what kinda pump I need etc but it would be a standalone system. Running on its own battery.
Taking heat out via the motor mounting plate is the best way forward imo. To optimize maybe use a thermally conducive epoxy to better connect the stator and the mounting plate.
Ideally you’d want something that turns into a solid. I purchased some for my own experiment I had planned but I put it on the backburner. I wanted to add cooling fins to my motor mounts
Someone on the forum somewhere posted a water cooled board that had computer radiators in the front and back, but I can’t for the life of me find it. I think it was in the DIWHY thread? But it might’ve been a sale posting.
You’re thinking “track width”. Interested to hear how it goes, I tried the wides for the first time at a local intro2speed last week and I was surprised how much harder it was to turn the board, wasn’t a fan at all.
One thing I’m unsure about when running this setup is when I verbalized staggering these out-runner motors Awhile back In conversation with @Titoxd1000 he mentioned that there is a possibility that the electric fields generated by the motors could I guess you could say crosstalk or interfere with each other somehow. Idk if this is something to worry about?
If there was interference I wonder if there is something I could put in between them to diffuse the crosstalk I would imagine going to the hall sensors?
Thoughts? I’m probably going to just try it, If nobody knows about a foreseeable issue with this setup.
