Abstract

The present invention relates to the technical field of rapid heat dissipation lasers, in particular to a laser with rapid heat dissipation function, comprising a casing, a heat dissipation mechanism is fixedly connected to the inside of the casing, and the heat dissipation mechanism includes a heat conduction tube, one end of the heat conduction cylinder is connected to the shell One end of the inner wall is fixedly connected, and the inner wall of the heat conduction cylinder is fixedly sleeved with a laser generator. In the present invention, a laser device with rapid heat dissipation function, through the setting of the annular cavity, the cooling liquid is directly in contact with the outer wall of the heat-conducting cylinder, and the heat exchange speed between the cooling liquid and the heat-conducting cylinder is increased, so that the laser generator can quickly Cooling and heat dissipation, through the setting of the deflector, break the high and low temperature stratification phenomenon of the coolant, make the temperature in the annular cavity uniform and stable, thereby increasing the stability of the laser generator during use, through the setting of two ventilation holes on the shell, A straight air passage is formed in the casing, which facilitates the rapid discharge of hot air and the intake of cold air, and realizes rapid heat dissipation of the laser generator.

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...
