Abstract:
An integral-type heat exchanger for an automobile, comprising:(1) a first heat exchanger including:a pair of first tanks, each first tank having a plane section perpendicular to a first surface thereof in which a plurality of first tube insertion holes are formed; anda plurality of first tubes to be inserted into said first tube insertion holes so as to connect said pair of first tanks; and(2) a second heat exchanger including:a pair of second tanks, each second tank having a substantially circular cross section and having a plurality of second tube insertion holes; anda plurality of second tubes to be inserted into said second tube insertion holes so as to connect said pair of second tanks; and(3) a plurality of fins disposed between a plurality of first tubes and between a plurality of second tubes;wherein axes of said first and second tube insertion holes are held in parallel with each other, and said (1) to (3) members are mounted on the automobile at the same time while said plane section of said first tank is brought into contact with, or is close to said second tank, andwherein said first tank has a substantially angular cross section, and a height of the substantially angular cross section of said first tank is larger than a width of the substantially angular cross sections,wherein a distance between the longitudinal central axes of said first and second tube insertion holes is less than a distance between the longitudinal central axes of said first and second pair of tanks.
