Abstract
The utility model discloses a heat abstractor who uses in LED lamps and lanterns, it includes can with the heat-conducting plate of the aluminium base board thermal contact of LED lamps and lanterns, has its face disjunctor short section of thick bamboo of perpendicular on this heat-conducting plate, and the radiating annular honeycomb structure core of overcoat is gone up to a short section of thick bamboo, realizes the heat conduction contact of annular honeycomb structure core and heat-conducting plate through connecting device, and it has the inlet port that forms the air convection with the empty chamber in the annular honeycomb structure core to open on the heat-conducting plate. The heat dissipation device adopting the structure can obviously reduce the weight of the LED lamp, and has large heat dissipation area and good heat dissipation effect.
Description
Technical field
The utility model relates to the heat abstractor in the light fixture, specifically, relates to the heat abstractor that high-power LED lamp is used.
Background technology
In existing high-power LED lamp, be provided with the heat abstractor with the lamp body disjunctor, this heat abstractor is to be provided with some fin radially of trend up and down around lamp body.When LED worked, the heat that they produced conducted to lamp body by aluminium base, and the fin by disjunctor is dispersed into surrounding space by the heat exchange with air then, made the operating temperature of LED be in suitable temperature range, thereby prolonged the service life of LED.Among the Chinese invention patent specification CN101182919A, the heat abstractor of this LED lamp has been done disclosure.
Yet the fin around the heat abstractor that this class LED light fixture is used, its lamp body is to adopt the milling mode to form, for guaranteeing the intensity of fin, its sheet thickness is thicker, thereby area of dissipation is little, weight is bigger, has not only increased the consumption of aluminum alloy materials, and has increased trouble to hanging to install.
Summary of the invention
The purpose of this utility model provides a kind of heat abstractor of using for the LED light fixture, this heat abstractor in light weight, and area of dissipation is big, good heat dissipation effect.
Above-mentioned purpose of the present utility model is achieved in that the heat abstractor that a kind of LED light fixture is used, it comprise can with a heat-conducting plate of the aluminium base thermo-contact of LED light fixture, the short tube that vertical its plate face of disjunctor is arranged on the heat-conducting plate, short tube is gone up the annular honeycomb core of a heat radiation of overcoat, and realize that by a jockey this annular honeycomb core contacts with the heat conduction of heat-conducting plate, on described heat-conducting plate, have at least with annular honeycomb core in empty chamber form cross-ventilated a plurality of air admission hole.
Described jockey can be a plectane that is pressed in annular honeycomb core end, has on the plate face and corresponding a plurality of ventholes of a plurality of air admission holes on the heat-conducting plate.
Described jockey can also be barrier or the cross-bar that is pressed on the annular honeycomb core end.
Described annular honeycomb core has a plurality of aluminum alloy flakes that get close to, the two sides of arbitrary thin slice radially respectively with adjacent two sheet surfaces alternately, be interrupted connection, forming and being close to a plurality of its cross sections with inside bunching elasticity trend mutually is hexagonal empty chamber.
After adopting said structure, because annular honeycomb is to be made of aluminum alloy flake, they have certain elasticity, good heat conductivity, institute takes up space few, and the empty chamber of formation is intensive, and not only area of dissipation is big, good heat dissipation effect, and weight greatly alleviates, and annular honeycomb core has the elasticity of inside bunching simultaneously, can bind round be enclosed within that shape and size are vicissitudinous and lack tin outside, easy to assembly, the scope of application is wide.
Description of drawings
Fig. 1 is the structure sectional side elevation of the heat abstractor used of the utility model LED light fixture.
Fig. 2 be Fig. 1 along A-A to cutaway view.
The specific embodiment
As Fig. 1, shown in Figure 2, the heat abstractor that a kind of LED light fixture that the utility model provides is used, it comprise can with a heat-conducting plate 2 of aluminium base 1 thermo-contact in the LED light fixture, the short tube 3 that the disjunctor of vertical its plate face is arranged on the heat-conducting plate, short tube is gone up the annular honeycomb core 5 that one in overcoat is used to dispel the heat, and realizes that by a jockey 6 annular honeycomb core 5 contacts with heat-conducting plate 2 reliable heat conduction.Annular honeycomb core 5 has a plurality of aluminum alloy flakes that get close to, and connection is interrupted along radially alternately surperficial with two adjacent thin slices 10,11 respectively in two sides of arbitrary thin slice 9.This connection is that hot pressing connects on the special hot pressing machine, forming and being close to a plurality of its cross sections with inside bunching elasticity trend mutually is hexagonal empty chamber 12, the radius that the cross-sectional area of empty chamber 12 is being attached honeycomb core 5 increases and increases, because aluminum alloy flake has certain elasticity, before hot pressing connects is the plane, so after constituting honeycomb core, each empty chamber all has tangential bunching trend.Therefore give and use assembling to bring convenience, promptly can tightly be enclosed within on shape, the differentiated part of size, on the short tube 3 as circle, oval-shaped other continuous surface as elastic tape.
On heat-conducting plate 2, have with annular honeycomb core in empty chamber 12 form cross-ventilated a plurality of air admission holes 4.
Above-mentioned jockey 6 is plectanes that are pressed in annular honeycomb core 5 ends, has on the plate face and corresponding a plurality of ventholes 7 of a plurality of air admission holes 4 on the heat-conducting plate 2.
Certainly jockey 6 can also be barrier or the cross-bar (not shown) that is pressed on the annular honeycomb core end.
The heat abstractor that LED light fixture of the present utility model is used, area of dissipation is big, and is in light weight, good heat dissipation effect.
