>I was thinking that the internal air and coolant tube in the left lung of the diagram could be kept completely closed in order to limit the need for a filter
I see, ofc that's a good idea. I forgot about that constraint.
>while the right lung would just expand and contract in order to circulate out the hot air as it is dispersed by a heat sink.
The more I think about this, the more I like the idea of devising a bellows arrangement. Not only can it be quite efficient mechanical-energy-wise, but it also will nicely mimic human breathing patterns. And that can only be a plus on cold, snuggly nights together with robowaifu. :^)
>The left lung would probably need a fan to keep air flowing and a pump to keep the liquid flowing,
Yes, unless we can take advantage of the bellows mechanism for the airflow on that side as well. And the liquid might be able to gain by some sort of bladders around the robowaifu (that could ostensibly be used for padding, shape & form, etc) that could be passive pumping action by her day-to-day movements, etc. Probably would only serve as a small ancillary boost to the fluid pump's basic work, but every little helps. It will all need to be analyzed in the end for cost/benefit against the energy budget. But things like temporarily storing momentum inside rotating flywheels is well understood now, so we might find little bonus energy savings like that with a little clever exploration.
>but my concern is that one or even a few coolers may not be enough.
Probably not, unless it was a big honking one. Any information on the available plate sizes on these things Anon?
>From what I can find, silicone is just a generally insulating material.
Yeah, makes sense ofc.
>There seem to be a few examples of heat spreading, which is very good, but none of them are elastic enough to be used as a skin
Hmm, that's interesting. Since from a systems engineering perspective, we already need to solve differing surface materials with differing softness/resiliency then we might just be able to capitalize on that fact by judicious use of these materials. Can you provide more information on your findings here?
>I don't see a better alternative to a silicone elastomer as skin, but given the low conductivity it could prove challenging
Good post Anon.
