A heat transferring apparatus may employ a heat exchanger with a fluid inlet and a fluid outlet and be coupled to a power exchange unit, which employs a driving fan fluid inlet, a series of inner fan blades to receive the fluid from the driving fan fluid inlet, and a rotable driving fan unit. The inner fan blades are attached to the rotable driving fan unit along with driving magnets. A rotatable driven fan unit has numerous outer fan blades and a series of imbedded driven magnets. The fluid drives the inner fan blades and flows into the heat exchanger. The outer fan blades force air through the heat exchanger and cools the fluid. A power transfer wall located between the inner magnets and the outer magnets transfers magnetic fields from the inner magnets to the outer magnets to impart rotation in the driven fan unit and outer fan blades.
