PURPOSE: A heat exchanger is provided to prevent a heat exchanger from moving, thereby minimizing a defect rate in brazing. CONSTITUTION: Upper and lower headers(10,20) are separated from each other at a certain gap, wherein slots for tube insertion are continuously formed in a length direction, combining grooves are formed at both ends, and support pieces(14) are bent by cut lines formed inside the combining grooves. A tank(30) is combined with the upper and lower headers for forming a passage. Plural tubes(40) have both ends connected between the slots for tube insertion of the upper and lower headers. Side supports(80) have length limiting parts(81) formed at both ends for limiting length of the tubes, and combining parts integratedly formed with the length limiting parts to be inserted into the combining grooves of the upper and lower headers.
