Thermoelectric cooling in downhole measuring tools

Weerasinghe, Rohitha

Abstract

Thermoelectric cooling is a highly effective and a novel technique used for cooling solid state circuitry inside downhole measuring equipment. A Peltier device in a deep well measuring tool works as a heat pump. The understanding of the thermal behaviour inside is important in designing the tools. For this study, thermal modelling is used, but accurate modelling of the Peltier device is crucial in predicting the thermal behaviour and subsequent thermal management of the tool. Present paper is based on numerical simulations using computation fluid dynamics and experimental analysis of the thermal behaviour inside an industry stand-ard deep well measuring tool based on a model based Peltier cooling device.
