Abstract
The utility model provides a light-emitting diode (LED) luminaire radiator suitable for LED luminaires for industry use. The LED luminaire radiator comprises heat dissipation holes (2), heat dissipation channels (5) and heat dissipation channels (6), wherein the heat dissipation holes (2) are arranged at the lower end of a side wall (1); the heat dissipation channels (5) are formed between the side wall (1) of the LED luminaire radiator and peripheral heat dissipation fins; the heat dissipation channels (6) are formed between an inner ring of the LED luminaire radiator and the heat dissipation fins; and three heat dissipation ways are formed respectively by the heat dissipation holes (2), the heat dissipation channels (5) and the heat dissipation channels (6). As the heat dissipation channels (5) and the heat dissipation channels (6) penetrating the upper surface and the lower surface of the radiator are arranged, when heat is transferred below the heat dissipation fins by a substrate located below the heat dissipation eel fins, the temperature of air below the heat dissipation fins can continuously rise, and meanwhile, nearby cold air can be continuously supplemented from the heat dissipation holes (2) at the lower end of the side wall (1) to generate convection to form a chimney effect, therefore, the air is convected to rapidly dissipate the heat in the manner of hot pressing, so that the heat is effectively dissipated. By adopting the structure, the weight of the luminaire can be reduced, and the material cost is saved.
Description
Technical field
The utility model relates to lighting design and heat dissipation technology field, is specifically related to a kind of employing louvre of the LED of being applicable to bulkhead lamp capable use and the passive type LED lamp lamp radiator of heat dissipation channel heat radiation.
Background technology
The heat transmission mainly contains hot conduction, thermal convection current and three kinds of modes of heat radiation.In the cooling system of LED light fixture, three kinds of heat transfer modes all have, and are main with heat conduction and thermal convection current still.The heat conductivity power depends on product material; Correlative study shows: the key that solves the LED heat dissipation problem is not to seek the material of high heat conductance; But change radiator structure or the radiating mode of LED, so the difference of heat spreader structures and the radiating effect difference that causes is a principal element, mainly consider the radiating effect of heat when lamp interior is transmitted with heat exchange pattern during design; Promptly how strengthening final cross-ventilation, is the final approach that solves the LED heat radiation.In the existing technology, the heat exchange of radiator and air can be divided into two kinds of active and passive types.Active is through equipment such as electric fans, quickens air and flows, thereby improve exchange rate, but increase extras such as electric fan, needs to consume more electric energy, and produces noise, makes structure complicacy etc. more.
Summary of the invention
The utility model technical problem to be solved provides LED lamp lamp radiator, solves passive heat radiation device high energy consumption, produces noise, baroque problem.
In order to solve the technical problem of the utility model; The technical scheme that the utility model adopts is following: a kind of LED lamp lamp radiator; The thermovent 2 that comprises sidewall 1 lower end, the heat dissipation channel 5 that constitutes between said LED lamp lamp radiator sidewall 1 and the peripheral heat radiation eel sheet, the heat dissipation channel 6 that constitutes between ring and the heat radiation eel sheet in it; And center screw 3 and bottom screw 4; Sidewall 1 is to be the annular curved surface in the center of circle with the radiator center, and the rectangle of sidewall 1 lower end, square or wedge shape thermovent 2 are distributed on around the sidewall, the heat dissipation channel 5 that constitutes between sidewall 1 and the peripheral heat radiation eel sheet; The heat dissipation channel 6 that constitutes between interior ring and the heat radiation eel sheet, heat dissipation channel 5 and the heat dissipation channel 6 vertical upper and lower surfaces that connect.Center screw 3 is used for the installation of radiator with bottom screw 4 and fixes.
The beneficial effect of the utility model is: thermovent 2, heat dissipation channel 5 and heat dissipation channel 6 form three kinds of heat radiation approach; Need not through any additional equipment; Only rely on the material and the structure of radiator self; Form very large heat-dissipating space, reduced thermal resistance, make the heat exchange of air and radiator reach best.
In addition, use this radiator can also alleviate light fixture weight, economical with materials cost.

The specific embodiment
Embodiment 1, a kind of LED lamp lamp radiator; The thermovent 2 that comprises sidewall 1 lower end, the heat dissipation channel 5 that constitutes between said LED lamp radiator sidewall 1 and the peripheral heat radiation eel sheet, the heat dissipation channel 6 that constitutes between ring and the heat radiation eel sheet in it; And center screw 3 and bottom screw 4; Sidewall 1 is to be the circular curved surface in the center of circle with the radiator center, and the thermovent 2 of sidewall 1 lower end is distributed on around the sidewall, the heat dissipation channel 5 that constitutes between sidewall 1 and the peripheral heat radiation eel sheet; The heat dissipation channel 6 that constitutes between interior ring and the heat radiation eel sheet, heat dissipation channel 5 and the heat dissipation channel 6 vertical upper and lower surfaces that connect.Center screw 3 is used for the installation of radiator with bottom screw 4 and fixes.
The thermovent 2 of embodiment 2, sidewall 1 lower end is rectangle, square or wedge shape, and all the other are with embodiment 1.
Below in conjunction with Figure of description the utility model is done further explain.
Referring to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, thermovent 2, heat dissipation channel 5 and heat dissipation channel 6 form three kinds of heat radiation approach.Owing to be provided with heat dissipation channel 5 and the heat dissipation channel 6 that runs through the radiator upper and lower surfaces; When the substrate that is positioned at heat radiation eel sheet below is delivered to the below of heat radiation eel sheet with heat; The temperature of the air of heat radiation eel sheet below can constantly rise, and the cold air simultaneously can replenish and produce convection current by continuous thermovent 2 from sidewall 1 lower end, forms " stack effect "; The mode that reaches with hot pressing makes cross-ventilation accelerate heat radiation, makes heat distributed effectively.
So even under the situation of passive heat radiation, this radiator also can form than higher air velocity field, let cold air heat radiation eel sheet surface abundant and radiator carry out heat exchange, take away heat rapidly, promote heat-sinking capability greatly.
