Abstract

The utility model discloses a heat dissipation fin module having an improved structure. The heat dissipation fin module comprises a heat dissipation fin and a copper block. A groove is formed in the heat dissipation fin, and the copper block just can be accommodated into the groove. The opening side of the groove is taken as the upper side surface of the heat dissipation fin, and at least one boss is arranged at the edge position at which the upper side surface of the heat dissipation fin and the groove are abutted. According to the utility model, the bosses are subjected to extrusion deformation through the riveting method so as to fix the copper block, the structure can be used to ensure that the copper block has a large drawing force, and the combination of the copper block and the heat dissipation fin is convenient and rapid, the utilization of a welding jig and a welding material is omitted, so the assembly cost is greatly reduced, the assembly efficiency is improved, and the advantage of good economic benefits can be realized.

Description

The fin module of architecture advances

Technical field

The utility model relates to a kind of heat radiating fin structure, particularly a kind of fin module of architecture advances.

Background technology

In the conventional art, in the fin module industry, copper billet all is directly to be welded on the fin by soldering, the baroque welding fixture of the general employing of this combined method, and pulling capacity is little, and economic benefit is not high.

The utility model content

In order to overcome above-mentioned defective; The utility model provides a kind of fin module of architecture advances, the fin module of this architecture advances fixedly copper billet the time pulling capacity big, and can improve the compactness that fin cooperates with copper billet; The transmission of being suitable for heat, economic benefit is high.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of fin module of architecture advances; Comprise fin and copper billet; Said fin is provided with groove; Copper billet be able to enough be placed in this groove, is the fin upper side with the slot opening side, and said fin upper side and the adjacent edge of groove are provided with at least one place boss.

As the further improvement of the utility model, the fin upper groove bottom surface that contacts with copper billet is a shiny surface.

As the further improvement of the utility model, the quantity of said boss is four, is uniformly distributed in the periphery at four angles of fin upper groove.

As the further improvement of the utility model, said boss height is 0.3mm.

The beneficial effect of the utility model is: the utility model is positioned over copper billet in the groove through in fin groove periphery boss being set, and through riveted way boss crimp is fixed copper billet; This structure guarantees that copper billet has big pulling capacity; And copper billet and fin combination are easily and fast, also saved welding fixture and welding material, saved assembly cost greatly; Improve packaging efficiency, can receive fine economic benefit.

Embodiment

Embodiment: a kind of fin 1 module of architecture advances, comprise fin 1 and copper billet 2, said fin 1 is provided with groove 3; Copper billet 2 be able to enough be placed in this groove 3, is fin 1 upper side with groove 3 open side, and said fin 1 upper side and groove 3 adjacent edges are provided with at least one place boss 4; During installation, copper billet 2 is positioned in the groove 3, then to boss 4 application of forces; Protruding many material are filled in the gap between copper billet 2 and groove 3 sidewalls boss 4 crimps; Copper billet 2 just forms interference fit with groove 3 and is riveted on together, and has played the fixation of copper billet 2, thereby has also deducted the structure division that copper billet 2 is fixed in the welding fixture; This combining structure is received good economic benefits, and has made very big contribution for the exploitation of heat radiation module industry.

The said fin that contacts with copper billet 21 upper groove 3 bottom surfaces are shiny surface.

The quantity of said boss 4 is four, is uniformly distributed in the periphery at four angles of fin 1 upper groove 3.

Said boss 4 highly is 0.3mm.
