Watercooled laptop idea

would mostly likely need TIM like graphene or similar. I would imagine that watercooling probably won't decrease temps as much as just a heatsink with fan. And I would also imagine the copper surfaces and TIM would become scratched or damage over time without a protective cover. However it's a novel idea.

So you would like to have a 90 °C hot copper plate on your lap?

 

I don't like to give destructive feedback, but I think it would burn your lap, which would be bad for a LAPtop.
So here's a different idea: The laptop's cooling depends on the heat dissipating surface and the airflow.
You could make a laptop with a round 120 mm air intake and a round 120 mm air exhaust in the bottom.
So there is no hot surface you can touch and you can force high airflow from the docking station.

It would be recessed so you wouldn't touch it - the copper plate on the dock "enters" the laptop. An optional cover would prevent you from sticking your fingies inside, as well.

I still see a problem with the thermal interface, like @DigitalDoofussaid.
You would probably have to screw the waterblock under the plate for good contact, which makes the laptop less mobile.

So I would go for the additional airflow.

This is as streamlined as its gonna get AND even that is killed off.

Water cooling concept is well established at this point, I know that your idea is different BUT having a 80 to 90c surface is not gonna fly with IEEE or EU.

Yeah, you could use multiple "locked" heatpipe connection points, but the cost and size of the "mechanics" would gimp you.

The other way to do it would be with a dual tech air cooled and water cooled "microloop" in the laptop, that is activated when the pump and cooling are attached to the rest of the loop in the dock, but maintenance and "reusable connection without leakage" are going to push it outside of the realm of "budgetary reality".

Maybe some kind of Peltier device(s) on the bottom that is(are) inactive unless docked could pass "regulatory" muster though.

I mean one way you could try to avoid these problems is have an insulative and protective cover over that would potentially magnetically retract or could be removed manually when docking it.
