Modine Supplies Titanium Heat Pipe Prototypes to NASA for Trip to Moon and Beyond

RACINE, Wis.--July 13, 2006--Modine Manufacturing Company , a world leader in designing and developing heating and cooling solutions for a diversified group of markets including electronics cooling, automotive, truck, heavy-duty and industrial, announced today that it has delivered, through its wholly owned subsidiary Thermacore International Inc., high temperature titanium heat pipes to NASA Glenn Research Center in Cleveland, Ohio. These heat pipes are evaluation prototypes in support of NASA's effort to develop radiator panels for rejecting heat from the power generation systems for long duration space and planetary base missions and could be used on trips to the moon, Jupiter and points further in space.

The Thermacore heat pipes are intended for use at temperatures up to 250 degrees Celsius. The delivered prototypes, which are 1.27 millimeters in diameter and 1.15 meters long, are made from Titanium and use water as the internal working fluid. These devices, capable of transporting over 500 watts, are produced at Thermacore's research and development facilities in Lancaster, Pennsylvania. NASA is pursuing the development of power generation systems capable of producing tens of kilowatts of electrical power for future missions to Jupiter and beyond.

The Brayton cycle is the leading power conversion system being evaluated by NASA. Just like all electric generating systems, the unconverted waste heat must be rejected. In this situation, it will be done with large radiator panels that contain heat pipes operating in the temperature range of 20 degrees Celsius to 250 degrees Celsius. To minimize weight, these heat pipes were constructed from Titanium.

"The first use of this heat pipe technology will most likely be on the moon for rejecting heat from the electric generating system for powering the lunar habitat. It would be quite an honor if our heat pipes become part of that mission." said Nelson Gernert, Research and Development Engineering Manager at Thermacore. The use of heat pipe technology on the lunar surface is the qualification for using them on other missions.

Heat pipe radiator panels to reject kilowatts of heat to the vacuum of space are not small in size. For example, a radiator panel to reject 100 kW of waste heat requires several hundred square feet of area and potentially hundreds of heat pipes. Since its beginning, Thermacore has been involved in the development of advanced Aerospace and Military related heat transfer technologies and products. "Ultimately, the leading edge technologies we developed for the Aerospace and Military sectors will filter into our cooling products used in computers, servers, and automobiles. The Aerospace/Military market for Thermacore has a circular benefit. It drives advances in our technology, which we use to benefit our OEM customers by cooling their products better. Our high volume manufacturing of these advanced products helps to drive down the price of the product, which in turn benefits the Aerospace/Military sector with reduced costs," explains Tom Cromwell, Thermacore's General Manager.
