PROBLEM TO BE SOLVED: To optimize a dimensional relation between tube and fin. SOLUTION: When the size of minor diameter (thickness) of a tube 110 is shown by B and the height of the fin is shown by HF, the relation between the size of the minor diameter B of the tube 110 and the height HF of the fin is specified so as to satisfy the relation of 2B+1.5 mm<=HF<=3.5B+2.5 mm. According to this method, a stress, generated in the fins 120, can be mitigated and the durability of the radiator 100 can be improved while making the heat exchanging core dense and increasing a heat radiating capacity. |
