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 surface, and a first surface in which a plurality of first tube insertion holes are formed; and a plurality of first tubes to be inserted into said first tube insertion holes so as to connect said pair of first tanks, wherein each of said plane surfaces is substantially parallel to a longitudinal axis of at least one of said plurality of first tubes; 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; and a 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, and 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 one of said first tanks and one of said second tanks.
