Described is a method of manufacturing a module with long-term stability even though it contains a non-heat-resistant material, in particular a photosensitizer. Two glass plates (1, 2) are connected to each other round their edges with an edge-sealing stru ...
Power Electronic components require cooling to limit junction temperatures to ensure long and reliable operation. Heat sinks are used for cooling the components. In applications which entail operation at altitudes, derating factors are provided by manufact ...
There is a broad range of techniques available to the engineer and that should be considered in a retrofit project to enhance the energy efficiency of an operating process. The two best known techniques and most often utilized are internal heat recovery by ...
The paper presents a comparison of transient calculations for two 80-MWt MOX-fuelled experimental accelerator-driven systems (XADS), one cooled by lead-bismuth eutectic and the other by helium. The results for protected (with accelerator beam trip) and unp ...
A heat sink that is particularly suitable for semiconductor components is made from a diamond-containing composite material. In addition to a diamond fraction amounting to 40-90% by volume, the composite material also contains 7 to 59% by volume copper or ...
This thesis presents a system approach with the aim to develop improved concepts for small capacity, high temperature lift air-water heat pumps. These are intended to replace fuel fired heating systems in the residential sector, which leads to a major redu ...
The project High Temperature Heat Pump has been completed in 2 phases. First a new type of scroll compressor with adapted injection port for vapor injection, was tested with an air-water heat pump (fig 2.2, 2.3). This type of heat pump reaches the extreme ...
The use of the heat-flux calorimeter BSC-81 as a chemostat is described. The technique was applied to study the heat generation rate by continuous cultures of the yeast Kluyveromyces fragilis NRRL 1109 as a function of specific growth rate. The maintenance ...
Synchronized oscillating cultures of Saccharomyces cerevisiae CBS 426 exhibit periodic oxidoreductive metab. The changing metab. is detectable by in situ heat-flux calorimetry in the BSC 81, which was operated as a chemostat in these expts. The measured me ...
We report thermally stable latched operation of a nonlinear Fabry-Perot device without heat sinking other than through the 0.5-mm GaAs substrate. The device has a 2-μm GaAs spacer and integrated dielectric mirrors with reflectivities of 91% and 99%. Operat ...
