Improved self-powered fan assembly

A self-powered fan assembly comprising:

• a lower heat exchanger comprising:
• a first module landing having a first heat transfer surface;
• and
• a heat transfer stem extending between, and thermally coupling, a heat source to the first module landing;
• a thermoelectric generator module having a hot side and an opposed cool side, the hot side of the thermoelectric generator module being thermally connected to the first heat transfer surface of the first module landing;
• an electric motor electrically coupled to the thermoelectric generator module;
• a fan operatively coupled to the electric motor;
• an upper heat exchanger comprising:
• a second module landing having a second heat transfer surface which is thermally connected to the cool side of the thermoelectric generator module;
• a vane array for dissipating heat;
• and
• one or more heat pipes extending between, and thermally coupling, the second module landing to the vane array;
• whereby a heat gradient created across the thermoelectric generator module generates power to operate the electric motor and, thereby, the fan.
