Abstract

The objective of the present invention is to provide a tubular heat exchanger capable of improving heat exchange efficiency and preventing deformation and damage thereof even in a high water-pressure environment. To this end, the present invention includes an outer jacket through which a heat medium is introduced and discharged; a combustion chamber coupled to the inside of the outer jacket so that a heat medium passage is formed between the combustion chamber and the outer jacket, and configured to perform combustion of a burner; a plurality of tubes formed in a flat shape for allowing combustion gas, which is generated in the combustion chamber, to flow along the inside of the combustion chamber and exchange heat with the heat medium; and a turbulator coupled to the inside of the tubes so as to induce generation of turbulence in a flow of the combustion gas.
