New Way of Freezing Using Heat Pipe Technology

Experts and Scientists have come up with a new way of freezing by using heat pipe technology and nitrogen liquid.

New Way of Freezing Using Heat Pipe TechnologyScientists claim to have engineered a new way of freezing as low as -180C using liquid nitrogen and heat pipe technology.

The new cryogenically-cooled heat pipe technology, engineered by scientists at Brunel University London, could have benefits in the medical sector and is said to avoid the dangers often associated with liquid nitrogen. “At the heart of the new system is the concept that what we needed was to be able to efficiently transfer cold,” explained Dr. Hussam Jouhara of Brunel’s Institute of Energy Futures. “The cold in our design comes from liquid nitrogen. But unlike conventional cold storage using the liquefied gas we don’t need to physically transfer the nitrogen. The cryogenic heat pipe is literally just moving the cold. “In safety terms this has major implications as in the US alone eight deaths a year are attributed to nitrogen asphyxiation. Our innovations mean the gas tanks can be situated safely outside in the open air.”

The system’s green and money-saving credentials are attributed to what the scientists’ describe as a highly efficient energy recovery process which promises a reduction of up to 50% reduction in liquid nitrogen use compared to conventional equipment. “Liquid nitrogen is expensive in both cash terms and energy consumption to produce,” added Dr. Jouhara. “And quite rightly there are strict health and safety rules because of the attendant dangers of asphyxiation. The Brunel system has no such special requirements.”Once installed heat pipes are regarded by engineers as a “fit and forget” technology as they have no moving parts and require no routine maintenance. Dr. Jouhara is partnering with industrial gases company Air Products to commercialise the new freezer technology. The company’s head of cryogenic technology development, Jon Trembley said: “After almost exactly 25 years, Air Products is back at Brunel University conducting leading cryogenic technology research in collaboration with Dr. Jouhara.
