New Thermal Management Strategies for Medical Devices

Heat pipes and vapor chambers are being utilized to address challenging thermal management requirements. In an increasing number of medical device applications, thermal issues limit the overall performance and reliability of the system. Basic thermal management strategies such as liquid cold plates, air cooled heat sinks, and thermal interface materials are becoming insufficient as stand-alone solutions. In many new medical applications, implementation of advanced thermal technologies such as heat pipes and vapor chambers are becoming an integral part of the thermal management solution. These technologies offer excellent heat transfer and heat spreading performance. Furthermore, they are passive (no energy, no moving parts), quiet, and reliable. Several medical devices, such as powered surgical forceps, skin/tissue contacting devices, and polymerase chain reaction (PCR)/thermocyclers already use these technologies, and more applications are emerging. A discussion of heat pipe and vapor chamber operation and selected medical device applications follows.

Using Electricity to Generate Alternative Fuel

Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.
