A New Generation of Cooling

Energy efficiency is key to the total cost of ownership of enclosure climate control solutions, and electricity consumption is a major element of operating costs. Hybrid technology, developed and patented by Rittal, combines conventional compression cooling, similar to what has been used in traditional air conditioners, with a heat pipe. The heat pipe uses evaporation of a working fluid in an evacuated tube.

New High Efficiency Piezoelectric Energy Harvesters

If we told you there’s a way to build piezoelectric energy harvesters that can produce more than ten-times the power output of commercial devices vibrating at the same frequency, would you believe us? It’s true! The key is to integrate stacks of polycrystalline lead zirconate-titanate Pb(Zr,Ti)03 (PZT) ceramic in design concepts that amplify your input forces, resulting in higher efficiency. And we’ll show you two ways to do that.

Development of Real-Time Battery Models for HIL testing of Battery Management Systems

The explosion in the use of electronic devices, electrified vehicles and decentralized power utilities has driven demand for rechargeable batteries. This has led to a significant increase in research investment into battery technologies to address challenges including thermal stability and battery life extension. This whitepaper outlines how such challenges can be overcome in the development of a Hardware-in-the-Loop (HIL) testing system for the Battery Management Systems (BMS) used in electrical energy storage products.

White, Electrically Conductive, Radiation-Stable, Thermal Control Coating

Goddard Space Flight Center, Greenbelt, Maryland A highly reflective, white conductive coating system was developed using a layered approach with a combination of commercially available white conductive pigments within a conductive binder system. The top coating is a space-stable, radiation-resistant, highly reflective coating that has been tailored to provide optimum reflectance properties and meet vacuum thermal surface resistivities. The combined layer is a mixture of a highly reflective, electrically dissipative coating and a moderately reflective but highly conductive pigment in a conductive binder. A second, underlying layer of conductive white coating offers optimum adhesion to metal substrates and the topcoat. The system vacuum resistivity at room temperature is approximately 1 × 109 ohms/sq, and has a solar absorptance of less than 0.13 as measured on a Cary 5000 spectrophotometer.

Piezoelectric Actuated Inchworm Motor (PAIM)

This linear piezoelectric actuator can operate at temperatures of 77 K or below. NASA’s Jet Propulsion Laboratory, Pasadena, California Conventional piezoelectric materials, such as PZTs, have reasonably high electromechanical coupling over 70%, and excellent performance at room temperature. However, their coupling factor (converting electrical to mechanical energy and vice versa) drops substantially at cryogenic temperatures, as the extrinsic contributions (domain wall motions) are almost frozen out below 130 K.
