The purpose of the utility model provides a kind of heat abstractor of heavy-duty diode pump laser, and it can improve radiating efficiency, solve the uneven problem of heat radiation, and a kind of heat abstractor of heavy-duty diode pump laser is provided.
The technical scheme of the utility model is: a kind of heat abstractor of heavy-duty diode pump laser is provided, and it soaks into laser medium in cooling fluid fully and cools off, and has taked the air-cooled mode that combines of sealing fluid cold-peace that laser medium is dispelled the heat.
Heat abstractor according to a kind of heavy-duty diode pump laser of this method design which comprises at least base, heat radiation chamber and fan, and it is characterized in that: its base is fluted, and laser medium places in the groove; The heat radiation chamber is cuboid cavity, cylinder cavity or cylindroid body structure, and the chamber of dispelling the heat forms confined space through bonding with base, and laser medium and cooling fluid are in the confined space of heat radiation chamber and base formation, and the heat radiation top of chamber has inlet, and liquid outlet is arranged at the bottom; Fan carries out wind-cooling heat dissipating in heat radiation side, chamber to the heat radiation chamber.
Described heat radiation chamber is a rectangular structure, and there are some heat radiation thorns on each surface of cuboid; The heat radiation thorn of end face is perpendicular to end face, and there is the angle of 45 degree the heat radiation thorn of side and side.
Described heat radiation chamber is cylinder or cylindroid body structure, and there are some heat radiation thorns heat radiation side, chamber, and there is the angle of 45 degree heat radiation thorn and side.
Described cooling fluid is an anti-icing fluid.
The characteristics of the utility model are: 1, laser medium is soaked in cooling fluid fully and cool off, low, the uneven problem of dispelling the heat of radiating efficiency of effectively having avoided traditional heat sink clamping laser medium heat radiation to cause.
2, design through rational heat-dissipating cavity shape to the splendid attire cooling fluid, effectively increase the surface-to-volume ratio in heat radiation chamber, help heat radiation, the while also is convenient to introduce air-cooled its radiating efficiency of further raising of fan.
3, take the air-cooled mode that combines of sealing fluid cold-peace that laser medium is dispelled the heat, improved radiating efficiency.

Embodiment
The heat dissipating method of this heavy-duty diode pump laser, it soaks into laser medium in cooling fluid fully and cools off, and has taked the air-cooled mode that combines of sealing fluid cold-peace that laser medium is dispelled the heat.
Like Fig. 1, shown in 2, the heat abstractor of this heavy-duty diode pump laser which comprises at least base 2, heat radiation chamber 7 and fan 1, and its base 2 is fluted 3, and laser medium places in the groove 3; Heat radiation chamber 7 is rectangular cavitys, and heat radiation chamber 7 forms confined space through bonding with base, and in the confined space that anti-icing fluid and laser bar 4 form with base 2 in heat radiation chamber 7, heat radiation top of chamber 6 has inlet 8, and liquid outlet 9 is arranged at the bottom; Fan 1 carries out wind-cooling heat dissipating in heat radiation 7 sides, chamber to heat radiation chamber 7.
Described heat radiation top of chamber 6 has heat radiation thorn 5, and heat radiation thorn 5 is perpendicular to end face; Heat radiation thorn 5 is all arranged in one week of side, and there is the angle of 45 degree heat radiation thorn 5 and heat radiation side, chamber.
As shown in Figure 5, base 2 is fluted 3, and groove 3 is used for fixing laser bar 4.
When laser is started working, open fan, laser bar 4 is passed to anti-icing fluid with heat.Anti-icing fluid constantly with heat transferred side heat radiation thorn 5 and cavity top 6, goes out cavity with hot type through convection type, and this is airtight liquid cooling process.Meanwhile, 1 pair of integral body of being made up of base 2 and heat radiation chamber 7 of fan is dispelled the heat.The combination of the air-cooled two kinds of radiating modes of sealing fluid cold-peace has effectively improved radiating efficiency.
Like Fig. 3, shown in 4, the structure of present embodiment and embodiment 1 is basic identical, and different is, and the cylindroid cavity has been adopted in its heat radiation chamber 7; The cylindroid cavity has only heat radiation thorn 5 is arranged in one week of side; Heat radiation thorn 5 and the angle of cavity side by 45 degree, heat radiation top of chamber 6 is planes, and inlet 9 is arranged.
As shown in Figure 6, in traditional heat sink clamping heat dissipating method, heat sink have the irregular contact face with laser bar; Can not be as Utopian plane; Actual is point-to-point contact, and radiating efficiency is low, heat radiation is inhomogeneous thereby caused, and then has influenced the quality of Laser Output Beam.
It is that laser bar soaks in cooling fluid fully and cools off that the utility model adopts laser medium; Avoided low, the uneven problem of dispelling the heat of radiating efficiency; And reasonably the heat-dissipating cavity shape of splendid attire cooling fluid is designed; Effectively increase the surface-to-volume ratio in heat radiation chamber, help heat radiation, also be convenient to introduce simultaneously air-cooled its radiating efficiency of further raising of fan; Take the air-cooled mode that combines of sealing fluid cold-peace that laser medium is dispelled the heat simultaneously, improved radiating efficiency.
