Résumé

Thermoelectricity has not undergone any important progress for the last twenty years, due mainly to the low efficiency of the heat sinks, because the Peltier pellet provides a high calorific power across a small surface. In this paper, a thorough study of the fin cooling for Peltier pellets has been carried out, by means of both an experimental model and also through computational fluid dynamics. A phase-change device called a thermosiphon has also been designed and optimized, which allows a uniform heat flow, decreasing in this way thermal resistance of the pellet. The work focuses on its hot face and paves the way to another study on cold face optimization. [Reprinted with permission from Elsevier. Copyright, 2005].
