<p><P>PROBLEM TO BE SOLVED: To provide a plate laminate type cooler for improving manufacturing efficiency and quality stability. <P>SOLUTION: A laminate fin 2 is mounted in a header frame body 1. The laminate fin 2 is composed of laminated plates. A top plate 3 is joined to an upper surface of the laminate fin 2. A step 6 is formed at a peripheral edge of the header frame body 1. The step 6 has an inner wall 7 and a flat surface 8. The top plate 3 is arranged inside an inner wall 7 of the step 6. Brazing material 9 is buried in a gap between the flat surface 8 of the step 6 and a lower surface of the top plate 3 to join the flat surface 8 and the top plate 3. The upper surface of the laminate fin 2 mounted in the header frame body 1 is separated further from a bottom surface of the header frame body 1 than the flat surface 8 of the step 6 of the header frame body 1. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
