Yes, that is correct in the case of reflection/absorption.canbb said:...paint. Silver to reflect heat away and black to absorb heat. .....
Theoretically, the surface of the foil doesn't look smooth enough to eliminate any possible small air gaps.Elinx said:Maybe nice for some people.
Was searching in old posts, I saw also an idea for improving heatconductivity mentioned by hefest
A lot of layers of aluminium foil until it fits snug.
The original source I found on German Pedelecforum. Guiri claims a better heat dissipation.
I think the publisher "Guiri" had his doubts too.sysrq said:........

Thanks for the input.hefest said:.....
I've used cheap ... China thermal pads stacked around the stator. ..... I've used some force to get the motor cover on....

The thermal conductivity should be 100x better as the air-gap.
So if the pads conduct the heat, you will could feel a warm casing.
I see these pads have a 5mm thickness.
Because of the force you have used, aren't you afraid that these sticky pads give a problem if you want the cover off again?
This solution is the most quick, easy and cheap I was thinking to do same at first too without removing the motor, but was thinking to use 50mm aluminium tape between pad and case for more easy disassembly of the cover.
There were already some brain sessions in the tsdz2 topic.jkekoni said:.. thermal conductive sponges?
.. metal foam or silicon?
... some kind of paste?
....Ferrofluid cannot be used here, I assume ?
Can you please give a link or picture of this copper wool?silentguy said:I am going to try 99.9% copper wool to fill the gap .....
The copper wool is only $10 on Amazon and used for rodent control.
That is a far-reaching addition. Filling the hollow space I see for the first time.silentguy said:.......
I also filled the air chambers on both sides of the motor case with the mesh and capped with custom shaped sandwiches......
