  • Publication number: 20240102745
    Abstract: Heat exchanger comprising a pair of header tanks which are arranged to be spaced apart from each other, a plurality of tubes formed in two columns in the width direction so that both ends are connected to the pair of header tanks, and a plurality of fins interposed between the tubes and coupled to the tubes. The header tank is configured so that a first tank and a second tank are respectively coupled to one header having a central bent portion in the center portion in the width direction, which provides easy assembling of headers and tanks of two heat exchangers. Thermal stress caused by the temperature difference between two heat exchanging media is blocked so that damage to a coupling portion where the two heat exchangers are coupled or a bonding portion formed through brazing can be prevented. Thus, leakage of the heat exchanging medium can be prevented.
