1. A heat exchanger, comprising:

  • a plurality of first fluid conduit assemblies, each of said first fluid conduit assemblies comprising a first fluid conduit disposed in a first generally planar region and having a first end and a second end, a first portion of said first fluid conduit extending in an inward spiral from said first end to a first area of said first generally planar region, a second portion of said first fluid conduit being connected in fluid communication with said first portion of said first fluid conduit and extending in an outward spiral form said first area of said first generally planar region toward sai second end of said first fluid conduit, said inward spiral extending in a rotational direction opposite to the rotational direction of said outward spiral, said second end of said first fluid conduit being connected in fluid communication with said second portion of said first fluid conduit, said first end of said first fluid conduit being connected in fluid communication with said first portion of said first fluid conduit, both said first and second ends of said first fluid conduit being disposed outwardly from said inward and outward spirals and within said first generally planar region; and

    a plurality of second fluid conduit assemblies, each of said second fluid conduit assemblies comprising a first plate and a second plate, said first and second plates being arranged in parallel association to define a second generally planar region therebetween, a spacer disposed between said first and second plates, said spacer defining a plurality of generally parallel channels within said second generally planar region between said first and second plates, each of said first generally planar regions of said plurality of said first fluid conduit assemblies being arranged in generally parallel association with a preselected one of said second generally planar regions of said plurality of second fluid conduit assemblies, each of said first plates of said plurality of second fluid conduit assemblies being connected in thermal communication with a preselected one of said first fluid conduits of said plurality of first conduit assemblies.
