Heat Exchanger for Automobile and Fabricating Method Thereof

A heat exchange of a vehicle comprising:

• a plurality of tubes (7), through which a heat exchanging fluid (90) flows, spaced apart from each other;
• an upper header pipe unit (3) coupled with upper ends of the tubes (7) to communicate with;
• a lower header pipe unit (6) coupled with lower ends of the tubes (7) to communicate with;
• the upper header pipe unit (3) including:
• a first header pipe (1) through which the heat exchanging fluid (90) enters;
• a second header pipe (2) through which the heat exchanging fluid (90) is discharged;
• and
• a plurality of separators to control flowing directions of the heat exchanging fluids (90) of the first and second header pipes (1 and 2);
• the lower header pipe unit (6) including:
• a third header pipe (4) to make the heat exchanging fluid (90) flow to a side;
• and
• a fourth header pipe (5) to make the heat exchanging fluid (90) flow in a direction opposite to the third header pipe (4);
• and
• the upper header pipe unit (3) and the lower header pipe unit (6) to comprise a pair of header pipes in which a header and a tank are integrally formed with each other,
• wherein the plurality of separators comprise:
• control separator (32) and end separator (33) respectively inserted into insertion groove (40) formed in the middle and one ends of the first and second header pipes (1 and 2) to control the flowing direction of the heat exchanging fluid;
• and
• inlet and outlet separator (31) inserted into insertion grooves (40) formed in the other ends of the first and second header pipes (1 and 2) to form an inlet (50) and an outlet (51) for the heat exchanging fluid,
• wherein the first and second header pipes (1 and 2) closely contact with each other due to the control separator (32), the end separator (33) and the inlet and outlet separator (31).
