Shenshi's PCHE Successfully Supports ASIPP's Supercritical CO₂ Cooling Loop System Debugging

The Printed Circuit Heat Exchanger (PCHE), independently developed and manufactured by Hangzhou Shenshi Energy Conservation Tech Co., Ltd. (referred to as “Shenshi”), has successfully completed full-process debugging in the Supercritical Carbon Dioxide (CO₂) Cooling Loop System at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). All key performance indicators have met or exceeded design requirements.

Significance of the Supercritical CO₂ Cooling Loop System

The Supercritical CO₂ Cooling Loop System is a critical component of the divertor engineering test platform for the China Fusion Engineering Test Reactor (CFETR) Comprehensive Research Facility (CRAFT) major scientific project. It provides an essential experimental foundation for verifying the feasibility of the Dual-Cooled (Supercritical CO₂ and Liquid Lithium-Lead) Blanket (COOL) technology.

This successful debugging marks a significant breakthrough in China's independent development of high-end heat exchange equipment and its application in nuclear energy systems. Supercritical CO₂ cycle cooling technology, with its advantages of high heat transfer efficiency, compact structure, and environmental friendliness, has become a key supporting technology in frontier fields such as nuclear energy and concentrated solar power for green energy conversion and efficient utilization.

Collaborative Achievement and Technical Highlights

This collaboration is the result of in-depth cooperation among Shenshi Tech, Xi'an Jiaotong University, China Nuclear Huayu, China Nuclear Huawei, and ASIPP. As a national-level specialized "Little Giant" enterprise, Shenshi Tech has profound technical expertise in high-efficiency energy-saving heat exchangers. Its PCHE products are renowned for high temperature and pressure resistance, compact size, and superior heat transfer efficiency.

During the debugging phase, the PCHE achieved efficient heat exchange of supercritical fluids under high-temperature and high-pressure conditions, with key indicators such as heat transfer efficiency and pressure drop surpassing design expectations. The results demonstrate that Shenshi's independently developed PCHE not only meets the heat exchange demands under extreme conditions but also exhibits excellent reliability and stability.

This achievement provides crucial technical support for ASIPP's nuclear fusion experimental devices and lays a solid foundation for China's future nuclear fusion energy development.

Future Outlook

Shenshi Tech will continue to partner with ASIPP, Xi'an Jiaotong University, and other institutions to deepen cooperation in advanced nuclear energy, supercritical CO₂ power generation, and other cutting-edge fields, jointly promoting innovation in China's energy technologies.
