Radiating fin and base combination structure

Abstract

The invention relates to a radiating fin and base combination structure design. The radiating fin and base combination structure comprises a base and a plurality of radiating fins, a plurality of adjacent grooves are arranged on the radiating base for respectively implanting the radiating fins in an inserting way, the radiating fins are tied at the bottom end to be stamped and form bending parts and wing hook parts which are intersected, so that the bottom ends of the radiating fins are inserted in the grooves of the radiating base in a matching manner and can be combined by burying or tightly clamped in the grooves by means of a pouring or extrusion manner, the radiating fins can be buried or clamped in the grooves of the radiating base by utilizing the bending parts and the wing hook parts which are intersected at the bottom end, so as to achieve the stable positioning and combining effects.

Description

technical field [0001] The present invention provides a combined structure design of a heat dissipation fin and a base, wherein the bottom ends of the heat dissipation fins are preset with mutually staggered bending parts and wing hook parts, so as to cooperate with the casting or extrusion method to make the heat dissipation fins The chip can be quickly and firmly combined with the groove of the heat dissipation base. Background technique [0002] The conventional heat sink is mainly composed of a base and a plurality of heat dissipation fins, or more than one heat pipe can also be embedded in the base. For the combination of the base and the heat dissipation fins, in addition to the traditional welding technology, there are also U.S. Patent No. 5014776 for invention is that the heat dissipation fins are pre-planted in the base groove, and then the heat dissipation fins are clamped and combined with the base groove by punching, so as to achieve the purpose of combining the ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned prior patent technology mainly pre-forms a drop-shaped, conical or circular larger protrusion at the bottom of the heat dissipation fin, and the opening of the base groove is large at the top and small at the bottom, so the heat dissipation fin can only be opened from The side of the base groove is inserted, and then punched and clamped to complete the combination. Since this design cannot be directly inserted into the base groove in a vertical direction, it will be quite complicated and inconvenient to assemble.

[0004] Or as in the U.S. Patent No. 6758262, although the heat dissipation fins are directly inserted into the groove of the base in a vertical direction, the clamping purpose can only be achieved by using the extrusion deformation on both sides of the groove of the base, and the clamping force is concentrated At the deformation position on both sides of the opening of the groove, there are only two point-shaped clamping forces. Therefore, the clamping effect is not good, and the role of stable combination cannot be exerted, and the uneven heights of the heat dissipation fins are prone to occur. phenomenon, and may shake or even fall off

In addition, there are also people who form a reflexed part or an L-shaped bent part at the bottom of the heat dissipation fins in advance, and then insert them into the groove of the base for stamping and bonding. Possible sideways deflection
