Plate-Fin Heat Exchanger Value-Added Assembly
Lytron recently added two new custom solution galleries to its website. These galleries feature photos and descriptions of cold plate and heat exchanger value-added assemblies that were designed and manufactured for OEM’s in the medical, military, traction, computer, semiconductor, and analytical instruments markets. The assembly pages also list value-added components that engineers can incorporate into your thermal solution for easier integration into your system.

There’s an article in Process Cooling magazine’s January/February 2010 issue regarding the phase out of R22 refrigerant. According to the U.S. Environmental Protection Agency’s (EPA’s) website, effective January 1, 2010, “Virgin R-22 may not be used in new equipment.” This regulation is part of the Montreal Protocol, which, as of September 2009, all countries in the United Nations have ratified in an effort to reduce the amount of ozone-depleting chemicals released into the air. If your equipment or process uses R22, you can legally continue to use R22 in that equipment or process until January 1, 2030. Continue

In the Boston Sunday Globe[1] newspaper this week, there was an article featuring the Boston Dynamics BigDog. The BigDog is a 240 lb (109 kg), 3 ft (0.9 m) long robot designed to carry loads up to 340 lbs (154 kg), run up to 4 miles/hr (6.4 km/hr), and even climb hills. Last week, Boston Dynamics announced it had landed a $32 million grant from the U.S. Pentagon’s Defense Advanced Research Projects Agency (DARPA) to develop the next generation of BigDog for use by U.S. Marines.

CDU Configuration Software for Liquid Cooled Cabinets
Lytron announced yesterday that it has launched a complimentary software for data centers. The software assists data center facility managers and engineers in determining the number of Coolant Distribution Units (CDUs) required to supply their liquid cooled cabinets. Users can select the specific makes and models of their liquid cooled cabinets and the software will automatically populate the program with the required flows and temperatures. The software can also be used to run thermal calculations for custom cabinet cooling configurations. It simplifies the sizing of a CDU and allows the user to quickly see the impact that changing flow rates, temperatures, and heat loads will have on their liquid cooling loop. Read the Full Press Release.

Stockholm, Sweden
An article written by Yevgeniy Sverdlik in the January issue of Data Center Dynamics FOCUS magazine, titled “Sweden pitches for data centers,” reviews the attractive pitch the Invest in Sweden Agency (ISA) has for data centers. The country boasts district heating and cooling systems that allow customers to feed their waste heat energy into the system and trade it for cooling energy. IBM is one of the companies taking advantage of this, using its waste heat to warm its own building as well as selling its excess heat back to the energy company in the form of hot water. Fortum, the energy company, uses seawater for cooling from about January through August. The company provides the cold water at a temperature of 6°C (43°F). Fortum recently built a thermal storage facility in a mountain, capable of storing 40MW worth of cooling. By taking advantage of its cold climate, Fortum is able to provide some of its Swedish customers with a heating and cooling value proposition that is better than in other areas of Europe. Continue

I recently read an article in Machine Design magazine titled “Tips to Improve Energy Efficiency.” [1] The article, written by Thomas Dwyer of Bosch Rexroth, highlighted the importance of right-sizing components and systems for energy efficiency. The article was specifically geared towards right-sizing of pneumatics, but right-sizing is important in all industries and applications. Designers sometimes oversize components in order to build in a margin of safety. However, as Dwyer pointed out, this safety factor can add quite a bit to the cost of operating your system. What may be less obvious, perhaps, is how this safety factor can also add significantly to the cost of designing, manufacturing, or shipping your component or system, as well as to the indirect cost of taking up valuable real estate.
