AIR TO AIR HEAT EXCHANGER ABSTRACT OF THE DISCLOSURE This is an air to air heat exchanger. A unit uti- lizing tubes inside a boxed area for the purpose of trans- ferring heat. Special positioning of these tubes allows efficient heat transfer and non-clogging of unit. Cold air travels inside of tubes and hot air around the exte- rior of them. Cold air chambers are insulated, eliminating external condensation. Interior condensation is drained by use of a slanted floor under the heat transfer tubes. Multiple air flow chambers in both cold and hot air passa- ges increase heat transfer and retard unit freeze up. Built in washing apparatus may be provided to facilitate unit maintenance. Construction materials may consist of acry- lics, plastic piping and metals having special coatings. Variable speed fans thermostatically controlled allow for variance in environmental temperatures. To conclude, the unit utilizes hot exhaust air to preheat incoming cold air.
