Semiconductor laser with automatic cooling device

Abstract

The invention relates to a semiconductor laser with an automatic cooling device. The semiconductor laser comprises a cooling shell for bearing a semiconductor laser shell, a temperature detection sensor and a controller, wherein a groove for accommodating the semiconductor laser shell is formed on the upper surface of the cooling shell; a side cooling pipe and a bottom cooling pipe are arranged in the cooling shell; the side cooling pipe is communicated with the bottom cooling pipe; the side cooling pipe is communicated with a cooling tank through a pipeline; the bottom cooling pipe is communicated with a conveying pump through a pipeline; the conveying pump is communicated with the cooling tank through a pipeline; the temperature detection sensor is arranged in the semiconductor laser shell and detects the internal temperature; and the controller is used for receiving a detection signal of the temperature detection sensor and is electrically connected with the conveying pump. The bottom of the semiconductor laser shell is cooled by employing the bottom cooling pipe, and the side of the lower end of the semiconductor laser shell is cooled by the side cooling pipe, so that the cooling efficiency is improved, the operating temperature requirement of the semiconductor laser shell is met, and normal operation of the semiconductor laser is guaranteed.

Description

technical field [0001] The invention relates to the technical field of semiconductor laser equipment, in particular to a semiconductor laser with an automatic cooling device in the technical field of semiconductor laser equipment. Background technique [0002] After the semiconductor laser works for a long time, it will generate a certain amount of heat inside, and with the accumulation of time, the higher temperature will affect the work of the semiconductor laser. In the prior art, there is an exhaust fan added to the semiconductor laser. The temperature is lowered, but the exhaust fan is used, the temperature inside the semiconductor laser is still very high, and the cooling effect is not good, so it cannot meet the temperature requirements of the semiconductor laser. Contents of the invention [0003] In view of the above technical problems, the present invention provides a semiconductor laser with an automatic cooling device, which can automatically cool down the semi...
