As shown, the heat dissipation fin for the refrigerator according to the present invention includes a refrigerant flow radiator 10, the upper radiator 20, the lower radiator 30.

The refrigerant flow radiator 10 is made of aluminum, is drawn and manufactured to have a rectangular cross section. In addition, a plurality of refrigerant communication holes 11 are formed in the longitudinal direction of the refrigerant flow radiator 10 in the longitudinal direction, and the plurality of refrigerant communication holes 11 are formed to be punched at a predetermined interval therebetween. The heat exchange medium (ex: refrigerant) is allowed to flow through the refrigerant communication hole 11.

The upper radiator 20 is installed on the upper surface of the refrigerant flow radiator 10 described above, and the width D2 of the upper radiator 20 is equal to the width D1 of the refrigerant flow radiator 10.

(Of course, the shape of the cutout 40 may be cut vertically, such as '│' in the width direction, to the upper radiator 20, depending on the user's embodiment.)

The lower radiator 30 is formed on the bottom surface of the refrigerant flow radiator 10 described above, and similarly to the upper radiator 20, the width D3 of the lower radiator 30 is also described above. It is formed to be equal to the width D1 of the sieve 10.

The lower radiator 30 is fixed to the bottom surface of the refrigerant flow radiator 10 in the longitudinal direction, and has a '∧' shaped cross section in the upper direction in the same length direction as the upper radiator 20. The first bent portion (A) is bent to form a bend, and the second bent portion (B) having a '∨' shaped cross section is bent, and the first and second bent portions (A, B) are bent Alternately alternately in the longitudinal direction of the heat dissipator 30 to be continuously bent in a sawtooth form. (The bending form is the same as the shape of the first and second bent portions A and B of the upper radiator 20 described above.)

That is, the lower heat dissipator 30 repeatedly forms the first bent portion A at the upper end in the longitudinal direction, and subsequently forms the second bent portion B at the lower end in the longitudinal direction. Of the plurality of first bent portion (A) is to be fixed to the bottom surface of the refrigerant flow radiator 10 described above.

In addition, the lower radiator 30 also has a plurality of cutouts 40 formed on the remaining surfaces except for portions that are bent toward the top or bottom, that is, the first and second bent portions A, B) the plurality of cutouts 40 are cut at predetermined intervals from each other in the width direction of the lower radiator 30 between each other, and the cutout portion 40 of the lower radiator 30 is also an upper radiator. In the same manner as the cutout mentioned in the description of (20), if the cutout portion 40 is cut in a '/' shape toward the left side in the widthwise center C of the lower heat sink 30, the lower heat sink ( The cutout portion 40 of the portion toward the right side in the widthwise center C of the 30 is cut in a '＼' cross-sectional shape, so that the left side in the widthwise center C of the lower heat sink 30 is '/', The right side has a cross-sectional shape of '좌' so that the left and right cutouts are symmetrical with each other, or on the contrary, the center of the width direction C of the lower heat sink 30 In the left side '＼' cross-sectional shape, the right side is cut to form a symmetrical mutually in the '/' cross-sectional shape so that the upper and lower surfaces of the lower radiator 30 communicate.
