Abstract: PURPOSE: A high efficiency heat exchanger using helical inner tube is provided to collect high temperature waste heat so as to reuse. CONSTITUTION: An inner tube is made of ceramic material, formed with an upper tube(21) and a lower tube(21') separating each other and inserted into a heat transfer pipe(11) and has a periphery spirally grooved. The heat transfer pipe is installed to air inlet side header blocks(41,41') and air outlet side header blocks(42,42') and installed to the air inlet side with a fixing flange and coupling bolts so that air flows therein through an inside and an outside of the inner tube simultaneously.
