Sandia cooler. Can it be applied to F1 engines?

[langwadt]

What???
You have to transfer the heat from the first stationary metal plate to the air, through the air gab and then back to the metal rotor.
Do you really want to tell me that this should be better than transferring the heat from a spinning rotor to air?
Still the surface area of the plates is relatively small especially when comparing to the big surface area of the rotor plates which take advantage of the air moving very quick over them.
I doubt this is better than having a huge surface area of a conventional cooler and moving some air over it for forced convection.

the point is not that it is better, it removes the same heat, the point is that it does it with less area, less power power to move it and less noise

The thickness of the air bearing could be very small so the thermal resistance doesn't have to be that big compared to the resistance from the fins to ambient.

Sure circulating fluid in and out of the rotating part would be nice but it would take a lot more power to drive it with seals
needed to contain the fluid

Sorry but I will keep using my home made liquid cooling for computer chips.
I have just designed a neat system that pipes the fluid into another room with a cooling tower.
Should be good to run my latest flight sim and to watch movies on the wall with the projector.
Seems a shame to get out of bed.

Sorry, no, I do not think there is a future for this idea.
There is no safety margin if it fails, the chips will burn.

would have to be a pretty old CPU, afaik all current pc type cpu have build thermal shutdown

Thermal shutdown works reasonably OK with a heat sink to spread the load.
No good for sudden temp increases without a sink though, the chip will fry before it cuts out.

I don't see how its any less of a safety margin than any other active cooling solution commonly employed. For most CPUs, none will last long without power, and the CPU will shut itself down before any damage can be done.

You're also missing the key point that dust doesn't accumulate on it. Nice feature if you have a data center with god knows how many units that you no longer need to clear the dust from.

[maatriks]

I have some troubles with the design:

1) How is it different from modern fans while keeping dust in mind? 2000rpm fans do accumulate dust. Obviously not as much as radiator fins but it does happen over time.

2) 2000 rpm "fan" spinning sounds everything but silent to me. Resulting air flow is much higher than usual fan generates and could be clearly audible.

3) It seems to operate only horizontally, 99% of CPU-s are mounted vertically.

Interesting idea, just some minor details are fuzzy and are not covered in video as well.

Due you need an upgrade. Lol have any flash coolers on that rig?

[PlatinumZealot]

I feel like making one of these sandia coolers and trying it out. Looks pretty simple.

This heat exchanger device works well as a CPU cooler because it achieves a high velocity airflow over a relatively large surface area in a compact package. While this approach is much more effective than a conventional static heat sink and fan for CPU cooling, it still is not as effective as liquid cooling a CPU. The problem with cooling CPUs is the limited area available for conducting heat out of the CPU package.

This Sandia cooler would not make a good heat exchange system for an F1 car. It would be quite heavy and bulky. Not to mention that you would need to spin the heat exchangers at high rpms. The air/liquid heat exchangers used in F1 actually work quite well. They have amazingly low drag and low weight. Plus no moving parts!

Personally I think the airflow through the sidepods at 100mph is quite enough

How do you plan to make it? the prototype was CNC machined, its a rather complex geometry. However if they were to mass produce it for the computing market, they could probably cast it at a lower cost.

[PlatinumZealot]

I know a CNC machine guy.
I would make just one to see, but its gonna cost maybe $100US to do just one, which is expensive because he has to do the program.. Then you have to buy the motor.. i don't know. If I get the time I might attempt it.

The KERS is water cooled as well is it?
And the Kers radiator has to be cooled by natural flow of air through it?
It would be interesting if you could put this cooler directly on the battery packs.
