Abstract

Echangeur thermique partitionné, unité de valorisation d'énergie thermique et dispositif de stérilisation associé L’invention concerne un échangeur thermique (1) comprenant:- une zone de circulation principale (2) apte à recevoir un fluide principal (5), et -des moyens de circulation aptes à recevoir un fluide secondaire et configurés assurer un échange thermique avec la zone de circulation principale (2),Caractérisé en ce que en ce que : • la zone de circulation principale (2) comprend une première partie (7) et une deuxième partie (9)distincte, et • les moyens de circulation comprennent • un premier circuit fluidique (6) agencé au contact de la première partie (7) de l'échangeur thermique (1) et destiné à recevoir le fluide secondaire de sorte à assurer un échange thermique entre le fluide secondaire et le fluide principal (5) circulant dans la première partie (7), • un deuxième circuit fluidique (8) agencé dans au contact de la deuxième partie (9) de l'échangeur thermique (1) et destiné à recevoir le fluide secondaire, de sorte à assurer un échange thermique entre le fluide secondaire et le fluide principal (5) circulant dans la deuxième partie (9), • le premier circuit fluidique (6) et le deuxième circuit fluidique (8) étant configurés pour être alternativement indépendants fluidiquement ou être connectés fluidiquement l'un à l'autre. La présente invention concerne le domaine de la récupération d'énergie et de l'optimisation de l'utilisation de l'énergie thermique. Elle trouve pour application particulièrement avantageuse le domaine des stérilisateurs utilisant de la chaleur de manière discontinue pour la mise en œuvre d'un cycle de stérilisation. Figure pour l’abrégé : Fig. 1Partitioned heat exchanger, thermal energy recovery unit and associated sterilization device The invention relates to a heat exchanger (1) comprising:- a main circulation zone (2) capable of receiving a main fluid (5), and - circulation means capable of receiving a secondary fluid and configured to ensure heat exchange with the main circulation zone (2), characterized in that in that: • the main circulation zone (2) comprises a first part (7) and a second separate part (9), and • the circulation means comprise • a first fluidic circuit (6) arranged in contact with the first part (7) of the heat exchanger (1) and intended to receive the secondary fluid so to ensure heat exchange between the secondary fluid and the main fluid (5) circulating in the first part (7), • a second fluid circuit (8) arranged in contact with the second part (9) of the heat exchanger ( 1) and intended to receive the secondary fluid, so as to ensure heat exchange between the secondary fluid and the main fluid (5) flowing in the second part (9), • the first fluid circuit (6) and the second fluid circuit (8) being configured to be alternately fluidly independent or fluidly connected to each other. The present invention relates to the field of energy recovery and optimization of the use of thermal energy. It finds for particularly advantageous application the field of sterilizers using heat in a discontinuous manner for the implementation of a sterilization cycle. Figure for abstract: Fig. 1
