In support of NASA's Global Precipitation Measurement (GPM) mission, Thermacore delivered its Constant Conductance heat pipes (CCHPs) to the agency. The company also provided its high thermally conductive k-Core structural components for the agency's thermal infrared sensor (TIRS) program supporting the Landsat Data Continuity Mission (LDCM).

Lancaster, Pa.-based Thermacore designed and fabricated the CCHPs for NASA's application. The CCHPs provide effective heat transfer (hundreds of watts) over long distances. According to the company, the maintenance-free heat pipes efficiently return the working fluid condensate to the evaporator.

The high-conductance structural components used on the LDCM TIRS instrument include a mount for a cryocooler, a thermal doubler in a radiator, and a thermally conductive link connecting a telescope enclosure to a radiator. With up to six times the conductance of solid aluminum designs and up to 20 percent lower mass, the k-Core components were able to resolve critical thermal management challenges on this platform.

NASA's GPM program seeks to measure the distribution, amount, rates and the associated heat release or precipitation throughout the world. Accurate global precipitation measurements will benefit scientists who study the weather and climate. NASA's TIRS program is one of two programs that develop scientific instruments for the Landsat Data Continuity Mission (LDCM) satellite. The TIRS instrument is a two-channel thermal imager that was developed to provide radiometrically calibrated, geo-Iocated thermal image data of the earth's surface.
