That's not an issue. The heat exchange, in this case between air and PCM, will occur across the walls of the tubes. I'm envisaging the PVC as the shell, not the tubes.

I will measure the on time and the off time of the compressor to get a rough estimate on what it likes and design around that.
That's where I started too. I used the track timing clock on the car's CD/MP3 player - precise to the nearest second - as a stopwatch, on my regular trips.

Another obscure option: ceramic weave forge insulation. Well kind of.
Imagine a yeti cooler is made of 2 inches of poly foam which equals R-10 value and can hold ice and what not, but has only an R-value of 5 per inch. Move to ceramic fiber insulation: R-10 per inch!
I can think of many uses from exhaust insulation for race cars (reduce heat soak), insulate an existing fridge, or in the case glue it to the roof of your vehicle and possibly the doors.
Similar to the 3m crystalline tint option the goal here is to keep heat out.

Maybe I could try it out in the ranger as the head liner has already failed. Then I could just yank the header and restore it and throw this stuff in behind it. lol

Or one could do exterior insulation.

If you can also spray water over it, the whole car would act like a swamp cooler
