PROBLEM TO BE SOLVED: To provide a heat exchanging device reducing pressure loss of supercharged air, and improved in vibration proofing property by improving rigidity in connection. SOLUTION: A plurality of heat exchangers 10u are successively connected through header tanks 11. The heat exchanger 10u is provided with a plurality of tubes 13 for circulating the fluid, and corrugated fins 14 disposed between the tubes 13 as core portions 12. The header tanks 11 comprise core plate portions 11a for joining neighborhoods of end portions of the plurality of tubes 13 to each other in each of the heat exchangers 10u. The core plate portions 11a are closely fixed and connected with each other. End sides of the plurality of tubes 13 are opened to closed spaces in the header tanks 11. COPYRIGHT: (C)2009,JPO&INPIT
