PURPOSE: A heat exchanger is provided to promote heat exchange through a simple structure as combustion gas passes through flat tube-shaped heat exchanging pipes. CONSTITUTION: A heat exchanger comprises multiple heat exchanging pipes(10), a front plate(20), a rear cover(30), ad an upper and a lower plate(40,50). The both ends of the heat exchanging pipe are curved to the front in a bow shape. The front plate comprises combining holes(21) formed at the left and the right side at regular intervals. The both ends of the heat exchanging pipe are inserted into the combining hole. The combustion gas is provided through the central part of the front plate to the heat exchanging pipe. The rear cover covers the heat exchanging pipe in the rear part of the heat exchanging pipe. The both ends of the rear cover are fixed to the front plate. |
