Disclosed herein is a heat exchanger in which a header in the heat exchanger is made of a material of plastic so that a regulator plate to define a passage of pipe can be formed freely. Also, not only a passage between pipes but also a passage between fine tubes in the same pipe can be formed. Accordingly, formation of a passage to accomplish maximal heat exchange efficiency is possible. <??>In addition, the heat exchange performance is improved by forming a more number of fine tubes having a less small diameter, compared to the pipes of the material of aluminum, using the pipes of the material of plastic. <??>The heat exchanger according to the present invention constructed as above can accomplish the improvement of heat exchange performance by the maximum of 30% over the heat exchanger of the material of aluminum. <IMAGE>
