2. How to remove heat from an IP66 enclosure?

Just out of curiosity, if the enclosure is sealed what will an oxigen sensor measure.I would conduct the heat outwards via a metal structure. But cosidering the heat your sensor generates, I would reconsider the polycarbonate choice. Polycarbonate max operating temperature is about $115,^circ C$. A metal enclosure would conduct the heat much faster to the environment

3. With modern computer liquid cooling systems and Peltier cooling, why can't we have a completely sealed IP66 computer case? You would just put the liquid heat exchanger outside the case.

I haven't seen one with internal liquid cooling, but I have seen plenty of IP67-rated computers. The Serener GW-01 comes to mind: Serener GW-01 (Fanless, IP67, for Intel DN2800MT)n GW-01 uses heatpipes to transfer heat to a heatsink that forms the top of the case. Websites state it as an IP67 rated design, but I'm pretty sure it would make the cut as IP68 as well because I've seen people use them in fully-submersed environments deeper than 1. 5 meters and they worked just fine. Teguar also carries a bunch of IP-rated computers, mostly panel PCs meant for environments like butcher shops (where everything has to be sprayed down daily) and car washes.Waterproof computers aren't common because they're typically very expensive, and not many people need them. There are not a lot of use-case scenarios where a desktop PC is required to be waterproof; and when that is needed, it's cheaper and usually more practical to just put a normal desktop PC inside of a NEMA enclosure or something similar. Waterproof laptops and tablets are in higher demand than waterproof desktops, but it doesn't make much sense to liquid-cool a laptop or tablet. There are tons of companies making waterproof tablet PCs (especially for the medical industry); and when it comes to waterproof laptops, Panasonic Toughbooks are pretty much the go-to.With modern computer liquid cooling systems and Peltier cooling, why can not we have a completely sealed IP66 computer case? You would just put the liquid heat exchanger outside the case.

4. Moisture Trapped in IP66 Enclosure

Here's what happened to a product I designed that was IP69K (Protection against powerful high temperature water jets). It was installed in China and failed after about a couple of years. When looked into there was about 1.5 inches of water slopping about. Seemingly a mystery.However, it turned out to be a progressive build up of humidity. Every night the product was turned-off and internally it started to cool over night. During that period the internal pressure lowered (because the internal air cooled) and it sucked-in high-humidity air from the surroundings. That settled out on top of the microscopic layer of water that was ingested the previous night. Gradually it built up until it reached a switch mode power supply then bang.The way we got out of this was selling the option of having a drain plug fitted and each order was processed with attention to that humidity problem.Silica gel will work but only has a limited lifespan before it needs to be replaced. A positive pressure inside will help - if it's sealed as good as you suggest you can buy slow leak gas cartridges that keep the pressure positive - they are used in the petrochem industry and are akin to flameproofing by using pressure to stop volatile gases entering and potentially being ignited
