Description

technical field [0001] The invention belongs to the technical field of internal environment control of wind-measuring laser radar, and in particular relates to a wind-measuring laser radar dehumidification device using semiconductor refrigeration and a working method thereof. Background technique [0002] As a new type of wind resource measurement device, wind lidar has many advantages such as rapid deployment, mobility, and arbitrary adjustment of measurement height, and plays an important role in more and more wind resource assessment processes. Precision equipment such as lasers, optical fibers, and industrial computers inside the lidar have extremely high requirements on the temperature and humidity in the lidar cavity. If the temperature and humidity exceed the fixed range, it will cause irreversible damage to precision equipment. At the same time, in the mountainous area of ​​southwest my country, the air humidity is high in autumn and winter, and the temperature is l...

AI Technical Summary

Problems solved by technology

In terms of refrigeration and dehumidification, the technology of using refrigerant cycle dehumidification is also partially applied, but the disadvantage of using refrigerant cycle dehumidification is that a refrigeration system needs to be installed inside the lidar, which increases the overall complexity and weight, and also increases virtually. The risk of system failure. In addition, the vibration of the compressor during operation also has an adverse effect on the accuracy and accuracy of the laser radar itself.
