Illinois researchers design high-power heat exchangers

Demonstrating next-generation energy technology, researchers at the University of Illinois at Urbana-Champaign are using topology optimization and metal 3D printing to design ultra-compact, high-power heat exchangers.

Used in most major industries – including energy, water, manufacturing, transportation, construction, electronic, chemical, petrochemical, agriculture and aerospace – heat exchangers transfer thermal energy from one medium to another.

Recent advancements in 3D printing allow the production of three-dimensional exchanger designs previously thought impossible. These new and innovative designs operate significantly more effectively and efficiently but require specific software tools and design methods to manufacture the high-performance devices.

Recognizing the need to unlock new, high-performing heat exchangers, Grainger College of Engineering researchers have developed software tools that enable new 3D heat exchanger designs.

The team started by studying a type of exchanger known as a tube-in-tube heat exchanger – where one tube is nested inside another tube. Tube-in-tube heat exchangers are commonly used in drinking water and building energy systems. Using a combination of the shape optimization software and additive manufacturing, the researchers designed fins (only made possible using metal 3D printing) internal to the tubes.
