Abstract

L'invention concerne un dispositif de refroidissement pour une première source de chaleur et pour une deuxième source de chaleur. Le dispositif de refroidissement comprend un premier système de refroidissement et au moins une première pompe d'agent de refroidissement. Un branchement de conduits pour agent de refroidissement est prévu entre la première source de chaleur, la deuxième source de chaleur et le système de refroidissement. Un ensemble thermostatique pourvu au moins de deux soupapes thermostatiques est prévu dans le branchement de conduits pour agent de refroidissement afin d'obtenir une répartition graduelle de température de l'agent de refroidissement.
