Medical Thermal Management

Medical devices increasingly offer more functionality within more compact packages to satisfy the market demands of the ward or the research lab.

At the same time these devices need to deal with the additional heat generated or to manage that heat output consistently and reliably to fully serve their purpose. On top of this medical
thermal management operates in an environment with its own particular challenges.

Miniaturisation increases heat

Electronic components are increasingly shrinking in order to meet the need for smaller higher power devices. For the medical market, this miniaturisation has enabled devices to become more portable, improved their ergonomics and precision and created smaller footprints. What was formerly a large machine can now be a handheld device. This requires designed thermal management to prolong its useful life to cope with the higher power densities and concentrated heat loads.

Medical Thermal Management Applications

The traditional approach to medical cooling includes refrigeration, Peltier or TEC and liquid cold plates, while the trend for passive heat transfer using heat sinks, heat pipes and vapour
chambers continues to increase for those applications where cost and compactness are key.

Versarien designs the best thermal management solution for the medical devices based upon its particular need and our capabilities in heat sinks, cold plates and bespoke designs based on copper foams. Suitable solutions can be devised for surgical devices, medical imaging equipment, bio-science equipment, biotechnology and research and sample screening.

Unique Issues in Medical Thermal Management

Given that our devices tend to be made from copper, they are not suitable for applications which require direct contact with human tissue due to the biocompatibility issues. This limits their use in some surgical devices as at no stage would we propose solutions with a risk to health or non-accreditation by the regulatory bodies or NEMA.

Our products do solve other key issues in medical thermal management such as precise temperature control, sterile environments and variable orientation. Which is why most of VTL’s work in this area is the result of specific conversations about the requirements of a product to develop the optimal thermal management solution.
