The invention relates to a laser cooling device for an aircraft laser guidance instrument, belonging to the field of laser refrigeration. The laser cooling device aims at solving the problem that theexisting ventilation cooling, water cooling, electricity refrigeration cooling and refrigeration machine set can not meet the cooling of the laser of the aircraft laser guidance instrument, and comprises a liquid ammonia steaming evaporative cooler, a liquid ammonia cylinder, a circulating water pump and an electromagnetic valve, wherein the liquid ammonia steaming evaporative cooler is a shell-and-tube structure and consists of a shell and a cooling water coil tube; the cooling water coil tube is arranged inside the shell; a water inlet and a water outlet of the cooling water coil pipe are exposed out of the shell; the liquid ammonia cylinder is internally filled with liquid ammonia; the electromagnetic valve is arranged between the liquid ammonia cylinder and the ammonia inlet of the shell; and the water outlet of the cooling water coil pipe is connected with the circulating water pump. The laser cooling device is used for the cooling of the laser of the aircraft laser guidance instrument.
Description
technical field [0001] The invention relates to a laser cooling device for aircraft laser guidance instruments, which belongs to the field of laser refrigeration. Background technique [0002] The aircraft laser guidance instrument system will generate a certain amount of heat during the working process, which will increase the temperature of the instrument itself and affect its working accuracy. In order to ensure the working accuracy of the laser-guided instrument and make it work within a certain temperature range, it is necessary to discharge the heat generated during the working process of the instrument in time. Therefore, it is necessary to develop a refrigeration system that can meet the requirements of the stable operation of the laser guidance instrument system of the aircraft. [0003] There are many ways to discharge the heat generated during the working process of the laser guidance instrument system: cooling methods such as ventilation cooling, water cooling, ...
