Cooling System

The development of efficient cryogenic cooling systems is essential for the reliable operation of superconducting technologies. Our work aims to create compact, stable, and energy-efficient cooling solutions that support long-term performance and practical application of superconducting devices.

Background and Motivation

Cryogenic cooling systems play a crucial role in enabling superconducting technologies by maintaining the low temperatures required for stable operation. Efficient cooling is essential to prevent local overheating, ensure uniform temperature distribution, and maintain the superconducting state under varying electromagnetic loads.

However, designing an effective cryogenic system is highly challenging due to the complex heat transfer processes and the strict thermal management requirements of superconducting devices.Our research focuses on understanding the thermal behaviour of cryogenic components, reducing thermal losses, and developing compact and reliable cooling solutions suitable for various superconducting applications.

System Design and Analysis

We focus on the development of a closed-loop gaseous helium (GHe) cooling system operating between 20 K and 50 K. In this approach, helium gas circulates continuously through a sealed loop, transferring heat from the superconducting coils to external cryocoolers via heat exchangers.

This design enables precise temperature control, uniform cooling, and efficient heat removal even under variable load conditions. The circulating helium not only improves cooling capacity but also enhances system reliability by avoiding liquid cryogen handling.

Analytical and numerical analyses are used to determine key design parameters such as flow rate, pressure drop, and allowable temperature gradients, ensuring that the cooling system can maintain the superconducting state safely and efficiently.
