Thermal Insulation of Small Instrumentation Probes

Résumé du livre

Some methods of preventing the rapid overheating of small instrumentation packages or probes when placed in a high temperature (200C) environment are presented in this report. Long term operation (greater than 30 minutes) requires active cooling and involves either greatly increased size or loss of independence of operation. The existing state of thermoelectric cooling is studied and rejected as a means of active cooling in this application. Short term operation (less than 30 minutes) is feasible using standard forms of insulation and heat sinks. (Author).
