PROBLEM TO BE SOLVED: To provide an optimal aluminum radiator satisfying preconditions for replacing a plastic tank by an aluminum tank, i.e., sharing of header/tank, simplification in the shape of the header/tank, sustention of the same performance as an existing plastic tank, initialization of deformation of an aluminum header/tank, and minimization of the thickness of material. SOLUTION: The aluminum radiator comprises a core comprising a plurality of tubes for passing a heat exchanging medium arranged side by side at a constant interval while satisfying a relation 10 mm <=T (outer width of tube)<=20 mm, and radiation pins arranged between the tubes, and a header tank comprising a pair of headers arranged in parallel at a constant interval while being coupled with the opposite ends of the tubes, a tank brazed to the header to form a part for passing the heat exchanging medium passed through the tubes and satisfying a relation 1.5<=H/T<=2.5 although H (inner height of tank)<=41 mm due to the outer width of tube, and end caps being coupled to the openings on the opposite sides of the tank. |
