Description
Technical field
The utility model relates to semiconductor laser radiator, particularly a kind of aluminium alloy laser radiator of high density directional stream-guidance.
Background technology
In recent years, rapidly, power is more and more higher in semiconductor laser development.But along with the increase of semiconductor laser power, used heat power is increasing, the heat radiation of device also becomes more difficult.Experimental result shows, the threshold current density, electro-optical efficiency, differential quantum efficency, laser spectrum etc. of semiconductor laser all have close relationship with temperature.Significantly work so the heat dissipation problem of research semiconductor is one.
The radiating mode of conventional semiconductor laser device has two kinds: one is liquid-cooling heat radiation mode, adopts the side that cooling fluid high velocity stream is excessively heat sink, the heat produced when taking away diode operation; The second is wind-cooling heat dissipating mode, utilizes fin side to be close to heat sink, is cooled diode by heat conducting mode.And liquid cooling heat radiation system volume is large, complex structure, transport difficult, environmental suitability are poor.The advantage that wind-cooling heat dissipating system but has that volume is little, cost is low, design free space is large and being widely adopted.
Conventional air-cooled radiator is made up of radiating fin and heat conducting base two parts.When air-flow is along the direction of vertical heat transfer pedestal, run into heat conducting base and stop, must flow to both sides along radiating fin, heat is taken to radiator both sides.
In the heat radiation structure design work of semiconductor laser, usually need the flow direction controlling hot-fluid, and the radiator of routine runs into the air-flow of vertical heat transfer pedestal, will inevitably air-flow guide radiator both sides, thus heat is taken to the device on radiator side, make the temperature of device increase, and be unfavorable for Duct design.In design work in the past, engineer is often installed specific structural member additional in the side of radiator and is carried out shutoff air-flow, and this structure often makes air-flow rebound, and produces uncontrollable sinuous flow, is unfavorable for heat radiation.
Summary of the invention
In view of the problems referred to above existing for prior art, the utility model is uncontrollable for existing air-cooled radiator air-flow, can not realize the present situation of directional stream-guidance, provides the high density aluminium alloy laser radiator that a kind of structure is simple, airflow direction is controlled.
The technical solution of the utility model is achieved in that
A kind of aluminium alloy laser radiator of high density directional stream-guidance, comprise radiating fin and heat conducting base, the contact-making surface of described radiating fin and heat conducting base is guide face, described guide face and base bottom surface α in a certain angle, and with radiating fin place plane orthogonal, described angle α=15 ° ~ 30 °.
Preferably, described radiating fin and heat conducting base adopt 6061 aluminium alloy overall wire cuttings to form.
Preferably, described radiating fin and heat conducting base adopt the surface treatment of electric conductive oxidation.
Further, described radiating fin spacing is less than 2.5mm.
Contrast with existing technology, the utility model structure is simpler, technique more simplifies, because radiating fin spacing is little, arranging density is large, especially guide face and base bottom surface in a certain angle, and the structure of guide face and fin place plane orthogonal, effectively can control airflow direction, when air-flow along vertical base bottom surface direction flowing time, reflect through guide face, can auto-steering, flow along reflection direction, without the need to by unnecessary reducing-flow structure part, thus provide larger free space for the heat dissipation design of semiconductor laser, achieve the controlled of airflow direction.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail, but protection range of the present utility model is not limited thereto.
A kind of aluminium alloy laser radiator of high density directional stream-guidance, as Fig. 1, shown in Fig. 2, comprise radiating fin 1.1 and heat conducting base 1.3, described radiating fin 1.1 and heat conducting base 1.3 adopt 6061 aluminium alloy wire cutting technology integral cutting to form, due to aluminium alloy, to have density little, the feature of good, the easy processing of thermal conductivity, makes that radiator itself is lightweight, thermal conductivity good.
Wherein, described radiating fin 1.1 and heat conducting base 1.3, carried out the process of surface treatment of electric conductive oxidation.Due to electric conductive oxidation technique, oxidated layer thickness only has 0.01-0.15 micron.So both can ensure the corrosion resistance of radiator, and not affect its good heat conductivility.
Described radiating fin 1.1 spacing is less than 2.5mm.Because radiating fin 1.1 spacing is little, density is large, effectively increases the area of dissipation of radiator, is conducive to the radiating efficiency increasing radiator.
Described guide face 1.2 and base bottom surface 1.4 in certain angle, and with fin place plane orthogonal, as shown in Figure 3; This corner dimension scope is between 15 ° ~ 30 °.The inclined-plane that guide face 1.2 and base bottom surface 1.4 are possesses good guide functions, when air-flow is along the direction flowing of vertical base bottom surface, through the reflection of guide face 1.2, and can along the direction flowing of reflection.
The aluminium alloy laser radiator of described high density directional stream-guidance has following remarkable advantage:
1, guide face and base bottom surface in a certain angle, and with fin place plane orthogonal.This structure effectively can control airflow direction, when the direction flowing of air-flow vertical base bottom surface, through guide face reflection, can auto-steering, and along reflection direction flowing, without the need to increasing unnecessary reducing-flow structure part.Thus provide larger free space for the heat dissipation design of semiconductor laser.
2, radiating fin spacing is little, density large, and efficiently radiates heat area is large, can significantly improve the heat-sinking capability of radiator.
3, quality is light, and volume is little, and processing is simple, easy to use, with low cost.
