Never heat TEG module more than 200˚C (TEG is assembled at 230˚C). 2. TEG module to be fixed between hot and cold exchangers with an optimal thermal contact for the best efficiency. Improper contact may reduce dT level and power output. 3. TEG polarity depends on applied hot and cold side orientation + Thot Tcold Tcold Thot - - + Installation 1. Mechanical Mounting. TEG is placed between two heat exchangers . This construction is fixed by screws or in another mechanical way. It is suitable for relatively large TEG modules (with dimensions 15x15mm2 and larger). Miniature TEG types may require another assembling methods. 1. Soldering. This method is suitable for a TEG module with metallized outside surfaces. RMT provides this option and also makes pre-tinning for TE generators. 2. Glueing. It is an up-to-date method that is used by many customers due to availability of glues with good thermoconductive properties. A glue is usually based on some epoxy compound filled with some thermoconductive material such as graphite or diamond powders, silver, SiN and others. The application of a specific type depends on application features and the type of a TEG module. ! 46 Warshavskoe shosse.
