PROBLEM TO BE SOLVED: To provide a liquid-cooled cooling apparatus whose assembly work is facilitated and strength is high.SOLUTION: A cooling liquid flowing body 2 of a liquid-cooled type cooling apparatus 1 is made of aluminum extrusion material of JIS A6000 type alloy of class T5. An aluminum inlet header is brazed at one end surface of a flow-in part of the cooling liquid flowing body 2, an aluminum outlet header 4 is brazed to one end surface of a flowing-out part 15 and an aluminum intermediate header 4 is brazed to the other end surface of the cooling liquid flowing body 2. Two headers 4 and 7 have clearances 18 and 23 and outward flanges 19 and 24. The clearance at the inlet header is communicated with a full flow-in side passage and a circumferential edge of the outward flange protrudes outwardly from one end surface of the flow-in part. A clearance part 18 of the outlet header 4 is communicated with a full flow-out side passage 11B and a circumferential edge of the outward flange 19 protrudes outwardly from one end surface of the flow-out part. The clearance part 23 of the intermediate header 7 is communicated with the full flow-in passage and the full flow-out passage 11B and a circumferential edge of the outward flange 24 protrudes outwardly from the outer circumferential edge of the other end surface.SELECTED DRAWING: Figure 2 |
