[0018] Furthermore, the device 1 comprises an intermediate hot air output pipe 2, for the output of a stream of intermediate hot air, and a final hot air output pipe 4, for the output of a stream of final hot air. [0019] Furthermore, the device 1 has, internally, a first separation chamber 10, into which leads the input pipe 6 and from which branches the intermediate hot air output pipe 2 and a further passage 12.

  • the device 1 has an accommodating compartment and comprises a rotating insert 16.
  • the rotating insert has an extension prevalently along an insert axis Z and comprises a head 18 and a tail 20.
  • the head and the tail are hollow inside, thus defining an insert pipe 22 in communication with the cold air output pipe 8.
  • the insert 16 is positioned so as to be aligned with the insert axis Z with the cold air output pipe 8 and with the final hot air output pipe 4.
  • the head 18 is accommodated in the accommodating compartment, so the room remaining in the compartment defines the final separation chamber 14.
  • the head 18 of the insert 16 has a head surface 30 substantially perpendicular to the insert axis Z .
  • a plurality of slits 32 angled with respect to the tangential direction, in agreement with one another, so as to produce a turbine effect .
  • the head 30 comprises a plurality of paddles 34 arranged in circumferential succession, protruding axially from the head surface 30, separated the one from the other circumferentially by said slits 32.

  • the separation and refrigeration device described above allows obtaining a considerable temperature gradient between the inflowing stream of air and the outflowing stream of cold air.
  • the structure of the device is particularly compact and therefore easy to use even in systems of reduced dimensions.
  • the device can be economically made, being made up of simple- geometry pieces, assembled together.
  • the device is of reduced dimensions and makes up, when assembled, a transportable whole.
  • a fuel cell is an electro-chemical device which allows obtaining electricity directly from certain substances, typically hydrogen and oxygen, without a heat combustion process occurring. The difference in potential stems from the flow of electrons produced during the chemical reaction.
  • the device cools the cell down to maintain a high level of efficiency.
