Protection Suit - Heat Version

If you think about protection, it doesn't always have to be against bullets or hits.
Heat is also a factor to be considered on construction sites or for travelling.

The basic idea would be to have a little space of, let's say, 5mm between the inner suit and the outer suit.

Inner Layer
The inner suit consists of a thin and breathable material like silk or artificial with similar attributes.

Hot Aisle
For a constant heat exchange the space between the 2 suits must be evenly spread and must not contain contact points to avoid friction. Friction leads to wounds and pain, so let's avoid that. To keep the space even there should be some kind of slightly flexible structure. Y- or double-Y-shaped maybe. But the Y-shaped space keeper needs to stick to something. In this case I would use a net of some kind, which touches, just touching, the inner suit.

Outer Layer
This Layer needs to consist of at least 3 sublayers.

1. A basic, heat-isolating and replaceable material. Some kind of foam would do the job.
2. The hard one. Against impacts. Carbon fiber composite material perhaps?
3. Heat not only comes with hot particles (Brownian molecular motion), but also with infra-red photons.
   So just glue some mirrors on the outside? No. But what about many small mirrors, maybe hexagon-shaped?
   In sandy areas or if used on construction sites the mirrors would be blunt quite quickly.
   The mirrors glass could be very hard, like sapphire, but that would be expensive.
   So we just calculate the obsolescence and attach the mirrors with very thin but strong magnets.

Heat Extraction
The body produces heat and no isolation is perfect, so that hot air has to go somewhere.
To release or cool the hot air down the back of the wearer would be good place.
This is in my oppinion the best place to store a machine, that cools the hot air.
To accomplish this exchange there's a need for energy. You could get it from batteries stored in the suit (flat LiPo accumulators fit everywhere) or small solar panels placed on the suit. The problem with the good airflow and exchange within the suit is topic for another post.
