The present invention provides a cooling device for a solar photovoltaic semiconductor laser, which relates to the technical field of semiconductor lasers, so as to solve the problem that in the process of heat dissipation and cooling, usually the interior of the semiconductor laser mount is always a high heat area, and heat dissipation and cooling only guide the heat output of the surface, resulting in During use, it is always in a high heat and high load operation state, which leads to the problem of reduced service life, including the protective shell; the protective shell is a rectangular box-shaped structure; the end sealing plate is a Y-shaped structure, and the upper and lower end sealing plates are respectively The upper and lower ends of the protective shell are blocked; the heat dissipation rear seat is a tapered structure adapted to the end sealing plate, and the heat dissipation rear seat is fixedly connected to the rear end of the protective shell. In the present invention, the heat conducting fins are bent plates twisted by 180 degrees, and the heat conducting fins are evenly distributed in the mounting seat in a longitudinal ring, which facilitates accelerated heat dissipation, and can play a role in assisting the rotation of the heat dissipation fan wheel to improve the heat dissipation and cooling effect.
Description
technical field [0001] The invention relates to the technical field of semiconductor lasers, and more specifically relates to a cooling device for solar photovoltaic semiconductor lasers. Background technique [0002] Usually the wavelength temperature coefficient of semiconductor laser is usually 0.2nm / K. In order to obtain an output wavelength of 797nm from an 808nm semiconductor laser, it needs to be cooled to around minus 30 degrees. At the same time, in order to stabilize the output wavelength of the laser, its temperature fluctuation should be less than 10mK. [0003] Existing cooling devices for semiconductor lasers, such as a cooling device for semiconductor lasers disclosed in Patent Application No. CN201310135883.2, have a water-cooled base, and the water-cooled base has a water channel for circulating cooling water. The dam structure in the dam structure divides the waterway into the first section, the second section and the third section connected, wherein the ...
