Problems solved by technology

However, most of the current radiators are integrally formed, such as formed by extrusion or cutting. Not only the shape cannot be changed, but also the shape is limited by the processing technology, and it is impossible to make a thin heat dissipation surface.

Embodiment Construction

[0020] See Figure 1-3 As shown, the heat sink 1 in the present invention is a thin sheet of aluminum alloy material, on which are provided structures such as buckles, stoppers, connecting pieces, holes, etc., and these structures are formed by punching the heat sink 1, and the direction of punching They are all the same, that is, one side of the heat sink 1 is a plane, and the other side is formed by stamping with the above-mentioned buckle, limiting piece, connecting piece, hole and other structures.

[0021] Specifically, the left and right sides of the heat sink 1 are straight sides 14 and arc sides 15 respectively. Among them, the upper and lower ends of one side of the straight side 14 are respectively formed with an upper buckle 4 and a lower buckle 5, and the arc edge 15 extends downward to form an extension 12, which is close to the straight side where the lower buckle 5 is located. 14, and a gap groove 6 is formed between the straight lower end 11 and the extended e...

Abstract

The invention relates to the technical field of radiating products, in particular to a nested radiator composed of a plurality of radiating fins. The nested radiator comprises a plurality of radiating fins forming the main body structure of the radiator, a clamp ring for fixing the main body structure of the radiator and a connection piece for connecting the products needing radiation; the main body structure of the radiator comprises a plurality of radiating fins which are buckled with each other; an upper buckling position and a lower buckling position are formed at the upper and lower ends of one side of each radiating fin respectively; and two adjacent radiating fins are buckled with each other through the formed upper buckling position and lower buckling position to form the main body structure of the radiator. The nested radiator is formed by stamping a sheet aluminum alloy material, thus the using amount of the material is reduced and the cost is lowered. The nested radiator is made from the sheet material and has big enough radiating surface; and gaps and slots are formed between and on the radiating fins, thereby promoting airflow and increasing the radiating speed.

Description

Technical field: [0001] The invention relates to the technical field of heat dissipation products, in particular to a nest type radiator composed of several heat dissipation fins. Background technique: [0002] With the rapid development of lighting products, the design of lamps is becoming more and more sophisticated, especially LED energy-saving lamps, which have become the trend of lamps and lanterns. However, the biggest problem with this kind of lamp is that it generates a lot of heat. In order to ensure that the chip of the lamp can work normally, it must be ensured that the heat generated during its operation can be dissipated in time so that the chip can be damaged by overheating. [0003] In order to prevent the lamp from overheating, it is necessary to dissipate heat in time. Usually, the lamp is combined with a heat sink with high thermal conductivity, and the heat generated inside the lamp is drawn out to the heat sink by way of heat conduction through the heat s...
