HeatSink that works well for smaller hub motors....

[DogDipstick]

My hubsink.

Phase change temperature from liquid to vapor is extreme. I can drop 30* C in an instant. Just a splash of water. The leash is zip tied around the hub and stays wet as you ride... almost invisible, swiping the surface of the hub.

I got baseline of 100A.. then 100A + 20mL ATF, and now 100A + 20mL ATF+ my Dogleash Hubsink. I have brought the Devil to his knees. No leaks, nothing but clean data. Looking for a longer leash now for a few more watts of cooling.

Got me some latent heat of evaporation going on. You know, good ol enthalpy of vaporization.

Hi there, great idea somewhat similar to the one ive seen on youtube recently. the other guy was wrapping a towel but this is much safer and a neat solution in comparison.

if youve got any idea to modify and implement this evaporation cooling to "scooter" hub motors only having access to the side shells somehow, please let me know. cheers.
