Supporting astrophysical breakthroughs: heat exchangers at the world’s largest observatory

Advanced cooling solutions for a critical component

Processor rooms are the nerve center of the ELT, where high-resolution photographs from space are stored and analysed. These rooms generate immense amounts of heat, requiring sophisticated cooling solutions to maintain the stable and precise conditions necessary for optimal performance.

Arsopi Thermal’s plate heat exchangers (PHEs) achieve this by using a series of thin, corrugated plates arranged to create alternating channels for hot and cold fluids. As the hot fluid from the processor rooms flows through one set of channels, the cold fluid passes through adjacent channels. The corrugated design maximizes the surface area for heat transfer, allowing the heat to move efficiently from the hot fluid to the cold fluid without the two mixing. This precise thermal exchange effectively dissipates excess heat, maintaining a stable environment critical for the reliable operation of the sensitive equipment.

By employing this advanced technology, the PHE’s ensure optimal cooling performance, energy efficiency, and reliability, enabling the ELT’s processor rooms to function flawlessly under demanding conditions. These plate heat exchangers use a corrugated plate design to maximise surface area for efficient heat transfer, allowing precise temperature control with minimal energy use, while their durability and reliability ensure uninterrupted performance.
