Abstract

L'invention concerne un système solide (19) de régulation de la température. Des éléments chauffants et de refroidissement solides, par exemple des éléments de refroidissement thermoélectriques et des éléments chauffants à coefficient de température positif, sont utilisés de manière séparée dans de nombreux dispositifs existants. Ces systèmes de l'état antérieur de la technique chauffent lentement et peuvent surchauffer. La présente invention concerne un élément de refroidissement thermoélectrique (20) et un élément chauffant (22) à coefficient de température positif intégrés dans un seul boîtier. Un dissipateur thermique (26) est partagé entre l'élément de refroidissement thermoélectrique et l'élément chauffant à coefficient de température positif. Cette combinaison permet d'obtenir un système de régulation de température chauffant plus rapidement et pourvu d'une plus grande puissance de chauffage. Un tel système de régulation de température peut être utilisé dans le coussin d'un siège.
