A magnet blower thermal conditioning system having a housing, a first blower subassembly in communication with a housing inlet for receiving an inlet fluid flow and a second blower subassembly in communication with the first blower subassembly as well as a housing outlet. Each of the blower subassemblies includes a sleeve shaped support, a plurality of spaced apart magnetic or electromagnetic plates extending radially from the sleeve supports. Conductive components are rotatably supported about the sleeve shaped supports, each incorporating a plurality of linearly spaced and radially projecting conductive plates which alternate with the pluralities of spaced and radially supported magnetic or electromagnetic plates. A motor or input drive rotates the conductive components relative to the magnetic/electromagnetic plates, creating high frequency oscillating magnetic fields and thermally conditioning the fluid flow as it is communicated in succession through the first and second blower subassemblies and through the housing outlet.

A magnet/electromagnet thermal conditioning blower system including a housing having a fluid inlet. A sleeve shaped support extends within the housing, a plurality of spaced apart magnetic/electromagnetic plates being communicated with the inlet, such that the plates extend radially from said sleeve support. A conductive component is rotatably supported about the sleeve support, the conductive component incorporating a plurality of linearly spaced apart and radially projecting conductive plates which alternate with the axially spaced and radially supported magnetic plates. The magnetic/electromagnetic plates include radially telescoping stem and seat portions for displacing the plates between extended positions which radially overlap with the conductive plates during a thermally conditioning mode thermal in which high frequency oscillating magnetic fields are conducted to the rotating component for outputting as a thermally conditioning fluid flow and inwardly retracted positions relative to the conductive plates during a non-thermally conditioning blower mode.

A clamshell heat exchanger for use in a combustion furnace of an HVAC system is presented that includes in one instance two passageways coupled by a turnaround passageway. The first passageway that receives the combustion products diverges. A cross section of the first passageway resembles a tear drop or air foil with the widest portion closest to the second passageway. The second passageway also diverges from the turnaround portion towards the outlet. The second passageway may include a baffle that forms two flow streams. Other embodiments are presented.

A furnace with a baffle assembly including at least one horizontal gap, and a heating, ventilation, and/or air conditioning (HVAC) system incorporating the same are provided. The furnace includes a furnace heat exchanger, a baffle assembly, and a fan. The baffle assembly is disposed adjacent to the furnace heat exchanger. The fan is in airflow communication with the furnace heat exchanger. The baffle assembly may include a first side and a second side. Each of the first side and the second side may respectively include a first section and a second section. A horizontal gap may be disposed between the first section and the second section (e.g., on either or both of the first side and the second side). The horizontal gap(s) may increase the efficiency of the furnace and/or the HVAC system.
