Abstract
A cooling apparatus having a cooling body with a plurality of fins arrayed in parallel on and fixed to a metal flat plate, wherein each of the fins is formed by bending at least one of upper and lower edge sections thereof at an angle or with notches and projections provided at multiple places in the edge sections on a line crossing the bending direction at right angles. The notch of one fin engages with the projection of the next fin when the fins are arranged in parallel on the metal flat plate.
Claims20
A cooling apparatus having a cooling structure, comprising:
- a metal plate having a flat surface;
- a plurality of fins arranged in parallel on and fixed to the flat surface of said metal plate, wherein each of said fins comprises:
- an upper edge section lying substantially in a first plane;
- a first middle section;
- and a lower edge section lying substantially in a second plane, said upper and lower edge sections being bent at a predetermined angle with respect to said first middle section along bending axes, at least one of said upper and lower edge sections having a plurality of notches and projections, said notches and projections extending along lines which are perpendicular to said bending axes and which are parallel to said first and second planes, wherein said notches of one fin engage with the projections of an adjacent fin when said fins are arranged in parallel on the flat surface of said metal plate.
2 more elements
A cooling apparatus having a cooling structure comprising:
- a metal plate having a flat suface;
- a plurality of fins arranged in parallel on and fixed to the flat surface of said metal plate, wherein each of said fins is bent into a Z-shaped form having an upper edge section, a middle section and a lower edge section, a bend between said lower edge section and said middle section being along a bending axis and said lower edge section having notch and projection means therein extending along lines which are perpendicular to said bending axis and which are parallel to said lower edge section, wherein said notch means engages with said projection means of another fin when said fins are arranged in parallel on the flat surface of said metal plate.
