Abstract

A radiator comprises a heat-dissipating substrate and a plurality of heat-dissipating fins arranged on the heat-dissipating substrate. The heat-dissipating fins are arranged in the width direction of the heat-dissipating substrate. The section of each heat-dissipating fin is trapezoidal. The two side faces of each heat-dissipating fin are provided with grooves respectively. According to the radiator, position distribution of the sections and space is just right, and alternating of hot air and cold air is better due to the section groove mode; compared with other section arrangement modes, the section groove mode is better on the condition of the same heat-dissipating area and size, the cost is lower, forming is easier to achieve, the weight is lighter, and the heat-dissipating substrate is applied to high-power LED lamps.

Description

A kind of radiator

Technical field

The utility model relates to radiator, is especially applied in the radiator on high-power LED lamp.

Background technology

LED lighting engineering develops into now, and the technology of its luminous component is very ripe, but also has a technical barrier that is difficult to overcome at present, is exactly the heat dissipation problem of LED light fixture.Front LED light fixture heat radiation is generally to rely on radiator to dispel the heat, and existing radiator is because design is unreasonable, causes its radiating efficiency low, and especially for high-power LED light fixture, existing radiator is not applicable.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of radiator, reasonable in design, and radiating effect is good.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of radiator, comprise heat-radiating substrate and be located at the some radiating fins on described heat-radiating substrate, described radiating fin arranges along heat-radiating substrate width, described radiating fin cross section is all trapezoidal, and the two sides of radiating fin are equipped with groove.Of the present utility model kind of radiator, just right in the position distribution in cross section and space, the mode of this section slot hot-air and cold air alternately aspect better, on identical area of dissipation and volume, other cross sectional arrangements mode is better relatively, forms background, better moulding, lightweight, be applicable to high-power LED light fixture.

As improvement: described radiating fin is divided into four groups, and every group of radiating fin group comprises two large fins and two little fins between two large fins.

As improvement, the top width of described large fin is 1.6 ~ 2.0mm, and the top width of little fin is 1.0 ~ 1.4mm.

As improvement, the height of described large fin is 56 ~ 62mm, and the height of little fin is 53 ~ 56mm.

As improvement, in every group of radiating fin, the distance between large fin and little fin is 8.5mm, and the distance between little fin and little fin is 8mm.

As improvement, in adjacent radiating fin group, the distance between immediate two radiating fins is 15 ~ 20mm.

As improvement, on described heat-radiating substrate, between adjacent radiating fin group, be provided with installing hole.

As improvement, the angle between described radiating fin two sides is 2 °.

As improvement, the two ends of described heat-radiating substrate are respectively equipped with backplate, and the medial surface of described backplate is provided with groove.

The beneficial effect that the utility model compared with prior art brought is:

Of the present utility model kind of radiator, just right in the position distribution in cross section and space, the mode of this section slot hot-air and cold air alternately aspect better, on identical area of dissipation and volume, other cross sectional arrangements mode is better relatively, forms background, better moulding, lightweight, be applicable to high-power LED light fixture.
