PURPOSE: An apparatus for surface treatment of heat exchanger capable of controlling power supply is provided to stably perform surface treatment of different sized heat exchangers at the same time. CONSTITUTION: The apparatus comprises a plurality of carriers on which assembled heat exchangers are mounted, a transfer part for sequentially transferring the plurality of carriers, a surface treatment part for continuously forming surface treatment film on the whole surface of the heat exchangers transferred by the carriers, a transfer device arranged at both sides of the surface treatment part to load and unload the heat exchanger mounted carriers to the surface treatment part, and a power supply impressing part(105) for impressing power supply to the heat exchangers mounted on the carriers when the carriers(101) are passing through the surface treatment part, wherein the power supply impressing part comprises upper and lower electrodes(131,131') arranged in two rows at upper and lower parts at both sides of the inside of chamber, the heat exchangers mounted in two rows on upper and lower sides of the central part of the carriers, and upper and lower power suppliers(132,132') installed at the outer part of the chamber so that different power supplies are supplied by connecting the upper and lower electrodes to negative power supply and connecting the heat exchangers(200) to positive power supply.
