Paper Abstract

High-power lasers require tremendous power consumption, generate large heat loads in short time periods, and have challenging cooling requirements. A cooling system of phase change energy storage that reduced the volume and weight by many times was proposed. The system included a laser cooling circuit and a phase change cooling circuit. Designed a phase change cold storage heat exchanger, which was the closed heat exchanger that the cooling circuit consisted of multiple bundles of copper tubes and the phase change material was paraffin. Based on the experimental results, designed another open phase change energy storage cooling system with better performance. Comparisons of these two types of phase-changing heat exchangers showed that choosing water as phase-changing material can get more accurate temperature control.
