Abstract
The utility model provides a laser cooling device which comprises a mounting plate; a laser module is fixedly arranged on the upper surface of the cooling device; the cooling device also comprises a graphite sheet between the laser module and the mounting plate. The laser cooling device has the beneficial effects that the quick heat conductivity of the layer of graphite sheet additionally arranged between the laser module and the mounting plate is utilized, so that the heat of the laser module can be quickly conducted to the whole breadth of the graphite sheet; meanwhile, the whole breadth tightly clings to the mounting plate and the mounting plate is cooled by air cooling or water cooling. In the way, the radiating area is increased equivalently, so that the radiating effect is better.
Description
[technical field]
The utility model relates to a kind of laser cooling technology, relates in particular to a kind of laser cooling device.
[background technology]

[embodiment]
clearer expression of purpose, technical scheme and effect for the utility model further specifies the utility model below in conjunction with accompanying drawing and embodiment.But should be appreciated that embodiment described herein only is used to explain the utility model, is not limited to the utility model.
Semiconductor laser module can produce heat in bright dipping, thus need cool off it, thus the work that it can be continued.A kind of laser cooling device is provided for this reason; It comprises a mounting panel 3, and this cooling device upper surface is fixed with laser module 1, in order further to improve the cooling effectiveness to laser; Between laser module 1 and mounting panel 3, add one deck graphite flake (figure does not show); Utilize the quick conductive property of graphite flake, make the heat of laser module 1 be transmitted to the whole breadth of graphite flake rapidly, like Fig. 1, shown in 2.
This graphite flake and mounting panel 3 are close to, and the contact area of this graphite flake and mounting panel 3 is greater than the contact area of laser module 1 with graphite flake, and graphite flake pressing plate 2 breadths are no more than the breadth of mounting panel 3.
In the present embodiment, this laser cooling device also comprises a graphite flake pressing plate 2, presses graphite flake on mounting panel 3.
Wherein, graphite flake pressing plate 2 covers fully and compresses graphite flake.
Fixing several laser modules 1 on mounting panel 3, the installation place of graphite flake pressing plate 2 corresponding laser modules 1 has installing port 21, avoids laser module 1, and is as shown in Figure 3.Each installing port 21 corresponding at least one laser module 1 is offered.In the present embodiment, installing port 21 is all offered in the installation place of graphite flake pressing plate 2 corresponding each laser module 1.In addition, can also offer the installation site of corresponding a plurality of laser modules 1 simultaneously by an installing port.
Because graphite flake has high-termal conductivity, so just with area of dissipation by the enlarged areas of the contact-making surface of original laser module 1 and mounting panel 3 contact area to graphite flake and mounting panel 3.The heat of laser module 1 conducts to graphite flake earlier, continues to conduct to mounting panel 3 again, through utilizing water-cooled, air-cooled mode individually or simultaneously, mounting panel 3 is cooled off.
In the present embodiment, mounting panel 3 is equipped with cooling water pipe, and is as shown in Figure 4.This cooling water pipe 4 can feed coolant, works the material with refrigerating function like water etc.
This laser cooling device can adopt air cooling way to reach radiating effect.
Particularly, can pass through mounting panel 3 ingresss of air, simultaneously can mounting panel 3 lower surfaces be provided with air cooling equipment accelerate near air flow, to reach the quickening cooling effect.
More than be merely the utility model preferred embodiment, but it does not limit the practical range of the utility model, promptly do not depart from equivalent variations and modification that the claim of the utility model is done, must belong to the protection range of the utility model.
