It means that the thermal management system must not only handle the high-power thermal load, but also mitigate thermal shocks caused by transient peak thermal loads, posing a significant challenge to the design of the thermal management system for airborne lasers.
Offer implications for the development of compact and lightweight airborne laser thermal management systems. To mitigate transient thermal shocks in lasers and reduce thermal stresses caused by temperature fluctuations, the use of phase change materials (PCMs) in thermal management systems is a viable solution.
Specifically, the structural defects, heterostructures, and inte-grated electrode architectures, all of which have been actively pursued for energy storage and conversion in recent years, can be facilely, efficiently, and controllably modulated by laser processing.
To cope with the peak thermal load during laser operation, the system must be equipped with a heat exchanger of equivalent power for real-time cooling. This necessity results in drawbacks such as large size, heavy weight, and high-power consumption for the thermal management system.
The present study introduces a two-dimensional transient heat transfer model for PFPCHEs, tailored for rapid design of heat exchangers and efficient management of transient thermal loads in laser systems.
Key processing parameters during the laser heating and transient cooling include the use of nanosecond pulse laser irradiation with a light intensity above 10 8 W cm −2 and an energy density exceeding 10 J cm −2, which induce plasma formation and promote the diffusion and incorporation of nitrogen into molten titanium.
