Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention and any combination thereof without creative efforts shall fall within the protection scope of the present invention.

[0019] Since phase change temperature control is a temperature control technology with great potential, by using the latent heat of phase change, the refrigerant can achieve a large amount of heat transfer at a very small mass flow rate, and has a high heat dissipation power density; When the phase change occurs, t...

Abstract

The invention provides a high-power laser heat radiating device which comprises a laser, a cavity, a heating resistor, and a storage box. Both the cavity and the storage box are provided with a phase change material inside. The cavity is in contact with the surface of the laser. The cavity and the storage box are connected with the heating resistor. The cavity and the storage box are communicated through at least two pipelines. All heat generated by the laser is exchanged and radiated through the phase change material. As the cavity and the storage box are connected with the heating resistor, the solidified phase change material in the cavity and in the storage box can be heated and melted through the heating resistor. The high-power laser heat radiating device of the invention radiates heat through the phase change material. The unit heat radiation volume is small. The efficiency of heat exchange is improved. The service life of the laser is prolonged. The service power of the laser is increased.

Description

technical field [0001] The present invention relates to the technical field of laser heat dissipation, and more particularly, to a high-power laser heat dissipation device. Background technique [0002] The types of lasers are increasing day by day, the development is extremely rapid, and the power used is getting higher and higher. High-power lasers have been applied to many fields of people's social life, such as detection, processing, communication, etc. The main problem facing high-power lasers at present is that the time for lasers to work stably is relatively short, which limits their practical applications to a large extent. The stable working time of the laser is mainly related to the heat dissipation of the laser. Due to factors such as conversion efficiency, the integration of light-emitting devices leads to heat enrichment, which will cause the junction temperature of the active region of the laser to rise, thereby reducing the photoelectric conversion efficiency ...
