PURPOSE: A heat exchanger is provided to prevent condensing efficiency and air conditioning efficiency reduction through preventing the damage of a pin and tube through decreasing the corrosion speed of the heat exchanger through expanding the contact surface of the pin and tube. CONSTITUTION: A heat exchanger comprises a first header tank(110), a second header tank(120), an inlet pipe(130), an outlet pipe(140), a plurality of tubes(150), a plurality of pins(160), and a protrusion part. The first header tank and the second header tank are formed by the coupling of a header and a tank. The inlet pipe or the outlet pipe is formed in the first header tank or the second header tank. A pin comprises a plurality of louvers. The protrusion part is formed in the curve part between the louvers of the pin. The protrusion part is contacted with a tube. |
