Abstract:
A blower assembly, comprising:a Peltier thermoelectric device having first and opposite sides and adapted to be connected to a source of power to emit waste thermal energy from the first side thereof and useful thermal energy from the opposite side; a first heat exchanger located in thermal communication with the first side of said Peltier thermoelectric device to collect the waste thermal energy emitted from said first side, said first heat exchanger having a first air flow path running therethrough; a second heat exchanger located in thermal communication with the opposite side of said Peltier thermoelectric device to collect the useful thermal energy emitted from said opposite side, said second heat exchanger having a second air flow path running therethrough; a fan for pumping a first supply of fan air through the first air flow path of said first heat exchanger for exhausting the waste thermal energy emitted from the first side of said Peltier thermoelectric device and collected by said first heat exchanger and a second supply of fan air through the second air flow path of said second heat exchanger for blowing the useful thermal energy emitted from the opposite side of said Peltier thermoelectric device and collected by said second heat exchanger to an application device or a space within which said blower assembly is located; and a housing having an upper housing portion and a lower housing portion, said upper housing portion enclosing said first heat exchanger and said lower housing portion enclosing said second heat exchanger, and said Peltier thermoelectric device being located between said first and second heat exchangers within said housing, and upper housing portion having first and second air passages formed therein and aligned with said fan, said fan pumping said first supply of fan air into the first air passage in said upper housing portion and through the first air flow path of said first heat exchanger enclosed by said upper housing portion and said second supply of fan air into the second air passage in said upper housing portion and through the second air flow path of said second heat exchanger enclosed by said lower housing portion.
