Abstract
The invention provides a laser heat sink and a method thereof. By arranging a refrigerator, high-pressure cool air which is a product of compressed air by passing the refrigerator enters the laser tube heat sink to radiate heat preferentially to a laser. As the main girder of the laser heat sink is a closed cavity with only one air inlet and one air outlet, wherein the air inlet is connected withthe air outlet of the laser tube heat sink and a pressure compensator is arranged in the air outlet, the device opens automatically to discharge air only when the internal air pressure of the main girder cavity is higher than the external air pressure while external air cannot enter the main girder cavity reversely to form unidirectional air flow, thus preventing external air containing dust and water from entering the main girder cavity and ensuring that the laser heat sink reaches a higher IP protection grade. As the refrigerator has sufficient refrigerating output, the air entering the main girder cavity from the air outlet of the heat sink after radiating heat to the laser radiates heat to optical devices and electric elements mounted inside and finally, the high-pressure cool air flow brings heat to outside from the pressure compensator, so as to realize the heat radiation to the whole device.
