The present invention relates to a heat exchanger including a pair of headers arranged to be spaced apart from each other, multiple tubes having both ends penetrated to the pair of headers and stacked with some space apart from each other at certain intervals, and multiple heat radiation fins arranged between the tubes, wherein the tubes include a first tube body having a first fluid path for movement of a heat exchanging fluid contained therein, a second tube body arranged in two rows spaced apart from the first tube body and having a second fluid path for movement of the heat exchanging fluid contained therein, and a connection arranged between the first and second tube bodies having both ends integrated with the first and second tube bodies, and having a height corresponding to the first and second tube bodies. Accordingly, the tubes have a united structure in the form of two rows, thereby reducing manufacturing costs, increasing productivity and reliability since assembly equipment can be simplified, efficiently discharging condensed water formed during the operation, preventing lowering of performance caused by condensed water by making condensed water of a front row not to affect second row, and improving performance and temperature distribution. |
