Abstract

In order to complete the design of cooling components within the limited envelope structure of a small laser and guarantee installation accuracy of the laser and cooling parts, the accuracy of transmitting telescope and heat dissipation of water tank, according to the given technical specifications of laser and the determined metal materials and welding methods, the detailed integration and miniaturization design of the cooling parts were carried out. Finite element analysis method and SolidWorks software were used to analyze the static state of the important parts in the cooling parts to ensure its accuracy and reliability. Finally, temperature characteristics test, shock and vibration characteristics test and impact vibration test under high and low temperatures were carried out. The results show that some quality problems, such as tearing and leakage, do not appear in the cooling parts. Beam divergence angle of 2.5mrad, output energy of 86mJ and pulse width of 12ns meet the design requirements. The design is stable and reliable, and can be used in a wide range of airborne laser range finders or indicators.
