Summary

The cooling of electronic components is of great value: it makes it possible to improve their capabilities, especially in the case of CMOS components. The purpose of this article is to present the principle and the design of a micro cooler dedicated to such an application. The originality of the approach concerns both the use of a thermodynamic system and the use of a micro-fabrication technology entirely compatible with the small scale of the component. The cooling function is performed by a pulsed gas in a small canal (pulse tube) made of glass and of silicon. Specific micro heat exchangers, also made of silicon, have been designed from the results of a study concerning both the pressure drop and the transitory thermal response. The actual micro-cooler performances are estimated in an experimental way by means of temperature and pressure measurements.
