Abstract
The utility model provides a fold-line-shaped turbulence radiator, which comprises radiating fins. The radiating fins are in the shapes of square brackets or are 'V'-shaped, an included angle between each two edges of the radiating fins is larger than 90 degrees, the radiating fins are symmetrical via a center line, and opening directions of the radiating fins are opposite. The fold-line-shaped turbulence radiator changes a straight structure form of traditional radiating fins and adopts a sectional curved fin structure, air among the fins of the radiator realizes better turbulence effect, more heat energy is taken away, and accordingly the radiating effect of the radiator is greatly increased.
Description
Technical field
The utility model relates to a kind of radiator, especially a kind of LED lamp broken line shape 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 may 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 straight structure, 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.
The utility model content
In order to solve existing technical problem in the background technology, the utility model proposes a kind of LED lamp radiator that turbulent effect is arranged, changed the straight version of traditional radiating fin, adopt the fin structure of segmentation bending, 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 utility model is: a kind of broken line shape turbulent flow radiator, comprise radiating fin, its special character is: the shape of described radiating fin is square brackets shape or " V " shape, and angle is greater than 90 degree between each limit, and described radiating fin is to be provided with on the contrary with center line symmetry, opening direction.
Above-mentioned broken line shape turbulent flow radiator also comprises base plate of radiator, is the welding of die casting or inserted sheet between described radiating fin and the base plate of radiator.
The utility model has the advantages that: radiator of the present utility model has structurally changed the straight version of traditional radiating fin, and has adopted the fin structure of segmentation bending.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 utility model;
The specific embodiment
Referring to Fig. 1, broken line shape turbulent flow radiator of the present utility model comprises radiating fin 1, base plate of radiator 2, radiating fin 1 is all fixing on base plate of radiator 2, fixed form can adopt extrusion process to realize, also can adopt the inserted sheet welding procedure to realize, radiating fin 1 is the segmentation bending 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, the heat energy that led light source produces could be spread out of as soon as possible and distributes like this.
