Mach E Frunk - Dry ICE. Check out my setup. Thoughts?

Right behind the front section is a radiator and fan (aka heat source if it's hot out). The drains should handle the overpressure if you haven't sealed them closed. I'd insulate the entire thing where any solid CO2 can touch it as -100 degrees is pretty damn cold for plastic, even if it's fiber reinforced.

I don’t think I’ve ever heard noise coming from the frunk area, and I use the frunk all the time.

Nonetheless, I’m quite intrigued by your quest for total sound isolation, and will be watching your threads. Would be quite the achievement if you manage to clamp noise down as good as Rolls Royce!

I didn't realize it can get that cold. Thanks for that.

Realistically I want to keep the Frunk cold for a week camping. Traditional Ice only seems to last a few days.

Ha! Days. My ice don't last 15 min in a Yeti cup out here haha. Let alone days camping. I have seriously got to move if others can keep ice for days in the frunk.

Note that the frunk vents are really not all that far from the HVAC air intake. My canine schnozz can detect the aromas of food placed in the frunk coming in through the A/C system. Not a good idea to have CO2 escaping the frunk and putrefying the air coming into the cabin.

Dry ice is about -110f or -78c. You're better off with a cooler than the frunk. The frunk, especially if the vehicle is in use is just a poor choice. Otherwise you need to just insulate the hell out of it. A cooler in a cooler is a better choice, kept in the shade.

 

[RickMachE]

I wouldn't.

 

[MobilityGrandMasterSteve]

I wouldn't.

Those are “dry” in that the liquid is sealed. But they’re not dry ice.

"dry" ice. Much like Smoke'less' fire pit.
How would one make ice -100 when the home freezer is all of -10

Oh good. You weren't seriously thinking of using dry ice, aka solid CO2, relatively directly in your frunk. I recommend you get a proper high quality cooler if you want to keep your ice for a week, because the frunk isn't insulated to act as a cooler.

Dry ice is very different than what you posted. I thought you were setting yourself up to look like you were driving a Whitesnake concert around.

Does the soundproofing work there? There is so much space between that backing and the firewall.

Maybe something like this would be a better option: https://www.koolatron.com/products/p25-fun-kool-cooler-24l
Or a 120 volt cooler if it's available at the campsite.
If you're boon docking a portable solar kit to help with the power consumption.
You could put a 12 volt power port with "fuse" in the frunk.
After all of the calculations, just regular ice would be cheaper and less troublesome.
