Abstract
The invention provides a turbulence radiator which comprises broken line-type or curve-shaped radiating fins. The LED lamp radiator with a turbulence effect adopts a segmentally-curved fin structure rather than the flat structure of the traditional radiating fin, so as to achieve better air turbulence between radiator fins, and take away more heat, and greatly improve the heat radiating efficiency of the radiator.
Description
Technical field
The present invention relates to a kind of radiator, especially a kind of LED lamp turbulent flow radiator.
Background technology
The LED light fixture generally is made up of several parts such as light source, radiator, Drive and Control Circuit and housings, and the radiator and the housing of portioned product unite two into one; The heat energy that the unit interval inner radiator distributes in air is followed following formula:
Q＝K×ΔT×A
Wherein: Q is the heat energy that radiator distributes in air, and Δ T is the temperature difference between radiator and the air, and A is the contact area of radiator and air; K is a coefficient; Relevant with the structure of radiator, material or the like many factors, span is also bigger, all maybe to more than 1000 from several.We can see by formula, and when conditions such as the shape of radiator, material were identical, the heat-sinking capability of wanting to improve radiator just needed to improve area of dissipation, tends to be accompanied by weight and the cost that increases light fixture and improve area of dissipation.Existing radiator all is straight heat radiation fin structure, and the air-flow of free convection is stable the rising on this flat construction, and the heat energy of taking away is limited, so just needs bigger area of dissipation, also just means the increase of material, the rising of cost.
Summary of the invention
In order to solve existing technical problem in the background technology; The present invention proposes a kind of LED lamp radiator that turbulent effect is arranged; Change the straight version of traditional radiating fin, adopted the crooked fin structure of segmentation, the turbulent flow that air better reaches between radiator fins; Take away more thermal energy, thereby improve the radiating efficiency of radiator greatly.
Technical solution of the present invention is: a kind of turbulent radiator, comprise radiating fin, and its special character is: the shape of said radiating fin is broken line shape or shaped form.
Above-mentioned broken line shape radiating fin is square brackets shape or " V " shape, and angle is spent greater than 90 between each limit.
Above-mentioned shaped form radiating fin is circular arc or waveform.
Above-mentioned radiating fin is with center line symmetry, the opposite setting of opening direction.
Above-mentioned turbulent radiator also comprises base plate of radiator, is the welding of die casting or inserted sheet between said radiating fin and the base plate of radiator.
Advantage of the present invention is: radiator of the present invention has structurally changed the straight version of traditional radiating fin, and has adopted the crooked fin structure of segmentation.This structure can realize the effect of turbulent flow, is not again unmanageable curvilinear structures.Under the situation of natural convection air, formed the turbulent flow of air between radiator fins, can take away more thermal energy like this, thereby improve the radiating efficiency of radiator greatly.The radiator of this structure has improved radiating efficiency, thereby has reduced the temperature of led chip, has prolonged service life, has reduced the use of radiator material on the other hand, has reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is second kind of example structure sketch map of the present invention;
Fig. 3 is the third example structure sketch map of the present invention.
The specific embodiment
Referring to Fig. 1; Turbulent radiator of the present invention comprises radiating fin 1, base plate of radiator 2, and radiating fin 1 is all fixing on base plate of radiator 2, and fixed form can adopt extrusion process to realize; Also can adopt the inserted sheet welding procedure to realize; Radiating fin 1 is that segmentation is crooked on air-flow direction, is square brackets shape, and forms the angle greater than 90 °; The air of free convection (to the significant air that dispels the heat) is along the Clearance Flow of radiating fin 1, and form turbulent flow (little eddy flow) thus improve the radiating efficiency of radiator.Base plate of radiator 2 is installed together with led light source in light fixture, could the heat energy that led light source produces be spread out of as soon as possible and distribute like this.
Referring to Fig. 2, Fig. 3, two specific embodiments of the present invention are respectively radiating fin 1 V-shaped setting and circular arc setting.
