Abstract
The efficiency of a heat exchanger is significantly improved by forming walls in an air flow structure, which has first grooves formed in the top surface of the structure and second grooves formed in the bottom surface of the structure, that block off alternating ends of the first and second grooves such that a first air source can only flow through the first grooves and a second air source can only flow through the second grooves.
