Description

A kind of buckle-type fins group

Technical field

The utility model relates to the fin of radiator, specifically is a kind of buckle-type fins group.

Background technology

Radiator is the common passive radiating device that is installed on computer processor, video card, board chip set, Led lamp, it generally includes base plate, fins group and heat pipe, by heat conducting mode the heat that above-mentioned electro-heat equipment produces is taken away, passive heat dissipation characteristics because of radiator, need not consumes energy, so radiator has obtained in daily life using widely.Yet, the production of traditional fins group be with aluminium ingot after shaping material by extrusion die under the condition of high temperature, become fin with machining mode, thereby traditional fins group has following defective: 1, material uses and is restricted, and the cost height; 2, complex manufacturing technology; 3, the product heat dispersion is bad.

The utility model content

At the problems referred to above of traditional heat-dissipating device fins group, the utility model provides the buckle-type fins group that a kind of manufacture craft is simple, the material range of choice is wide, with low cost and heat dispersion is high, and scheme of the present utility model is:

A kind of buckle-type fins group comprises at least two fins, and described each fin is rectangular; On two relative edge's edge of described each fin, be formed with the extension block of bending respectively, the extension block position on each fin over against, described each extension block bending angle is the right angle, all described extension block overbending directions are identical; The edge of described extension block is provided with first recess, and described first recess is positioned at the side that described extension block is connected with described fin, and the A/F of described first recess is not less than the base width of described first recess; The opposite edges of described first recess is provided with projection, and described first recess and described convex shape coupling are conflict by first recess on the described extension block and projection between the described fin and are connected.

Preferably, described extension block is an even number, and described extension block five equilibrium on two opposite edges of described fin distributes.

Preferably, the edge of described fin is provided with second recess, and described second recess is positioned at the side that described fin is connected with described extension block; The degree of depth of described second recess is greater than the thickness of described extension block; Described extension block is positioned at described second recess.

Preferably, the projection on the described extension block is provided with the first technology breach, and the described first technology breach is positioned at the top of described projection.

Preferably, the projection on the described extension block is provided with the second technology breach, and the described second technology breach is positioned at two sides of described projection.

Preferably, described first recess is V-shaped.

Above-mentioned utility model scheme has following advantage: adopt mechanical type to conflict between each fin of fins group and connect, its processing technology is simple, and the convenient thin material that uses is made fin, makes fins group increase number of fins and area; Spacing equates to make the air channel unimpeded between fins group monolithic and the monolithic, strengthens the radiating effect of fins group.And selectivity is wider in factors such as the cost of material, heat dispersion.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.

Shown in Fig. 1～4, one flat fins 1, fin 1 rectangular structure, on two length edges of fin 1, be respectively equipped with two extension blocks 2, extension block 2 also is a rectangular configuration, extension block 2 with a lateral edges that fin 1 is connected on also to be provided with the 21 whole punching presses of first recess, 21, the first recesses V-shaped, opposite edges at first recess 21 is provided with a projection 22, the shape of projection 22 and the form fit of first recess 21; Extension block 2 distributes at branches such as fin 1 edges, and extension block 2 extends the back to the same side bending from fin 1 edge, and plane, extension block 2 place and plane, fin 1 place be 90 ° vertical;

Above-mentioned fin 1 is provided with more than 1, stacked in parallel setting between the fin 1, and the extension block 2 of fin 1 is conflict by first recess 21 on the extension block 2 and projection 22 between the adjacent fin 1 and connects into fins group towards the same side; For guaranteeing that projection 22 A/Fs that can be interspersed in adjacent first recess, 21, the first recesses 21 are not less than the base width of first recess 21; For guaranteeing the frictional force of projection 22 and first recess 21, the form fit of projection 22 and first recess 21.

When extension block 2 was located at two widthwise edges of fin 1, extension block 2 and fin 1 were also with above-mentioned setting.

Preferred version as the foregoing description scheme, extension block 2 can be for more than 1 or 1 in the quantity at each bar length edge of rectangle fin 1, so, extension block 2 is at the even number that adds up at 1 two length edges of rectangle fin, be average friction interlock dynamics of disperseing between the extension block 2, extension block 2 distributes at the branches such as edge of fin 1.
