A heat exchanger is provided to remove any additional steps for joining tubes to headers by forming heat exchangers in various shapes by joining basic pipes integrating tubes and headers simply. A heat exchanger includes a basic pipe(10) formed with tube parts(11) in the hollow tubular shape for coolant flow and expansion parts(12) formed at both ends of the tube parts, and covers(20) coupled with the expansion parts of the basic pipe for forming first and second header tanks. |
