Heat exchanger using 3 piece type header pipe assembly and manufacturing method thereof

In groups of this invention relates to a heat exchanger with three-piece type header pipe assembly and its manufacturing method with him, and more particularly, heat which is a, a header pipe assembly coupled in communication with the bottom of the heat exchange tubes which are mutually predetermined distance apart, when changing the communication hole size and location is formed for the heat exchange the coolant flow between the coolant passage, to compensate for the disadvantages that must be each time modifying unit header part and tank, coupled to the header pipe assembly of claim 1, the second header pipe and that between the said partition wall, and by forming as a flange beam-shaped partition wall, communication holes, by processing only the partition wall modified in the formation, and changes do not require unnecessary modification of the other parts so as to obtain the effect of reducing the manufacturing cost due to the load and productivity forming two sides made of a pair respectively at the lower portion of the first plate, 2 by applying, but protrudes form the flange, by differently forming the spaced interval and the separation distance between the first flange between the first flange, the other of the first and second headers each other size pipes each adapted to couple to the first and second flanges, the first and second headers each of the refrigerant heat exchanger 3 so as to adjust a flow rate different from the piece type header pipe assembly and its manufacturing method that flow into the pipe and relates to a heat exchanger using the same. A heat exchanger, the header pipe, the communication, flow path, heat exchange, partition, three-piece
