PURPOSE: A heat exchanger is provided to enlarge a heat exchange area by forming multiple micro channel units in a rectangular structure and forming water flow paths in a zigzag shape. CONSTITUTION: A heat exchanger comprises a first micro channel unit (120), a second micro channel unit, and a third micro channel unit. The first micro channel unit is bent in a rectangular shape, and one end thereof is connected to a gas inlet pipe (110). A flow path, where gas flowing through the gas inlet pipe flows in, is formed in the first micro channel unit. The second micro channel unit is formed on the inner side of the first micro channel unit in a rectangular shape, and one end thereof is connected to the other end of the first micro channel unit. A flow path connected to the flow path of the first micro channel unit is formed in the second micro channel unit. The third micro channel unit is formed on the inner side of the second micro channel unit in a rectangular shape, and one end thereof is connected to the other end of the second micro channel unit. A flow path connected to the flow path of the second micro channel unit is formed in the third micro channel unit.
