Description

A kind of Assembled cooling fin

Technical field

This utility model relates to a kind of fin, specifically a kind of Assembled cooling fin.

Background technology

Fin is a kind of device dispelled the heat to the easy heat-generating electronic elements in electrical equipment, how by aluminium alloy, pyrite or bronze Make tabular, lamellar, splintery etc..General fin to be in use coated with last layer at electronic component and radiating rib contact surface and lead Hot silicone grease, the heat making components and parts send more effectively is transmitted on fin, then in fin is dispersed into surrounding air. Traditional fin is all the structure of full wafer, needs to install or remove whole fin during installing/dismounting, the most not side Just, and each electronic component is required for the fin of fixed dimension, it is impossible to be used on other electronic components, poor universality.

Summary of the invention

Fix for solving the heat sink sizes of traditional inconvenient and fixing electronic component of fin installing/dismounting, general Property difference technical problem, this utility model provides a kind of Assembled cooling fin.

A kind of Assembled cooling fin, including some fin A and some fin B, it is characterised in that fin A is with scattered Backing B includes that main heat sink, main heat sink lower surface are provided with some heat sinks, and four sides of the main heat sink of fin A set Having the groove being shaped as cuboid, four sides of the main heat sink of fin B are provided with corresponding with described groove shapes convex Platform；Described some fin A and some fin B are when combination, and the boss of fin B side is connected to adjacent fin In the groove of A side.

The cross section of described main heat sink is square, and the length of side is 3-5CM.

Described groove and boss be shaped as cuboid.

The beneficial effects of the utility model are:

A kind of Assembled cooling fin of this utility model uses groove and the fin of adjacent fin A main heat sink side The mode of the boss clamping of B main heat sink side, can be adjusted flexibly the area of fin radiator portion, and versatility is good and pacifies Dress convenient disassembly.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model Assembled cooling fin；

Fig. 2 is the front view of this utility model fin A；

Fig. 3 is the front view of this utility model fin B.

In figure, each parts labelling is as follows: 1, main heat sink, and 2, heat sink, 3, groove, 4, boss.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical scheme in this utility model embodiment is clearly and completely described.

As it can be seen, a kind of Assembled cooling fin, some fin A and some fin B combine, fin A Include that main heat sink 1 length of side that cross section is foursquare main heat sink 1, fin A and fin B is equal with fin B, main Heat sink 1 lower surface is provided with some heat sinks 2, and 1 four sides of the main heat sink of fin A are provided with the groove being shaped as cuboid 1 four sides of the main heat sink of 3, fin B are provided with the cuboid boss 4 corresponding with the groove 3 of fin A.

A kind of Assembled cooling fin of this utility model is when combining in the way of Fig. 1, and fin A and fin B alternately arranges Row, fin B main heat sink 1 side boss 5 be connected in the groove 3 of adjacent fin A main heat sink 1 side；Dissipate Main heat sink 1 length of side of backing A and fin B is 3CM, can according to the size of electronic component adjust the quantity of fin from And adjust area of dissipation.

A kind of Assembled cooling fin of this utility model uses the mode of adjacent fin A and fin B combination, Ke Yiling Live and adjust the size of radiator portion, add versatility and the easy installation and removal of fin.

Claims (3)

1. an Assembled cooling fin, including some fin A and some fin B, it is characterised in that fin A and heat radiation Sheet B includes that main heat sink (1), main heat sink (1) lower surface are provided with some heat sinks (2), the main heat sink (1) of fin A Four sides are provided with the groove (3) being shaped as cuboid, and four sides of the main heat sink (1) of fin B are provided with described The boss (4) that groove (3) shape is corresponding；Described some fin A and some fin B combination time, fin B side Boss (4) is connected in the groove (3) of adjacent fin A side.

Assembled cooling fin the most according to claim 1, it is characterised in that the cross section of described main heat sink (1) is Square, the length of side is 3-5CM.

Assembled cooling fin the most according to claim 1, it is characterised in that described groove (3) and the shape of boss (4) For cuboid.
