TEST STAND FOR STUDYING OPERATION CHARACTERISTICS OF STIRLING ENGINES

摘要

The invention relates to a test stand for studying the operation characteristics of a low-power Stirling engine. According to the invention, the stand comprises a heating assembly consisting of an aluminium block () placed in the area of an expansion chamber, which has on its sides some metal screens () heated by the radiation emitted by some lamps () mounted on some mobile supports which can move along some rolling tracks (), thereby modifying the quantity of heat transferred from the lamps () to the two screens (), as well as a cooling assembly consisting of an aluminium block () placed in the area of a compression chamber, which is cooled by means of some batteries () with Peltier elements, the hot face thereof being cooled by means of some radiators () under the effect of the cold air circulated by means of some fans ().
