<p>Disclosed is a heat exchanger having pressure resistance. According to the present invention, the heat exchanger having pressure resistance comprises multiple heat exchange tubes arranged to allow the heat exchange water of a boiler to flow therein, and having openings on both ends thereof; and headers connecting both ends of the heat exchange tubes, and allowing the heat exchange water to be supplied or recovered, wherein the header includes multiple chambers in which both of the ends of a pair of the heat exchange tubes are embedded; and a fixing member coupled to each of both of the ends of the heat exchange tubes, and sealing the chambers when coupled to the opening of the header. According to the present invention, a connection portion between the end of the heat exchange tube and the header is strengthened to bear high pressure.</p> |
