Laser with rapid heat dissipation function

Abstract

The invention relates to the technical field of rapid heat dissipation lasers, in particular to a laser with a rapid heat dissipation function. The laser comprises a shell, a heat dissipation mechanism is fixedly connected to the interior of the shell, the heat dissipation mechanism comprises a heat conduction cylinder, and one end of the heat conduction cylinder is fixedly connected with the inner side wall of one end of the shell, and the inner side wall of the heat conduction cylinder is fixedly sleeved with a laser generator. According to the laser with the rapid heat dissipation function,through the arrangement of an annular cavity, cooling liquid makes direct contact with the outer side wall of the heat conduction cylinder, the heat exchange speed between the cooling liquid and theheat conduction cylinder is increased, and the laser generator can achieve rapid cooling and heat dissipation, the high-lower temperature stratification phenomenon can be broken through the arrangement of a flow guide plate, so that the temperature in the annular cavity is uniform and stable, the use stability of the laser generator is improved, a straight air duct is formed in the shell through two vent holes in the shell, hot air is conveniently and quickly exhausted, cold air is conveniently sucked in, and rapid heat dissipation of the laser generator is achieved.

Description

technical field [0001] The invention relates to the technical field of fast heat dissipation lasers, in particular to a laser with a fast heat dissipation function. Background technique [0002] When the laser is working, it will generate a lot of heat energy, which will cause the working medium of the laser to heat up, thus affecting the wavelength, output power and mode stability of the laser. The laser usually works at a constant temperature, so heat dissipation or constant temperature components are required to ensure The laser active medium is always at a constant temperature. [0003] Most existing lasers use water cooling to dissipate heat. By connecting the water cooling block to the water circulation system, the water cooling block is in contact with the heating part to take away the heat. The contact area between the water cooling block and the heating part is small, the heat dissipation speed is not high, and the heat dissipation efficiency is relatively high Low...
