Suspicously absent in the diagram.. dust and particles.. i guess its a closed inner air circuit transporting the heat towards some large scale shedding surface.
The air is full with fats that will penetrate any filter, and long term build up there... With the extra heat contributing to the issue. Personally I don't think it can work in an open loop system.
Also, is this something similar to the https://en.wikipedia.org/wiki/Venturi_effect ?
