Abstract

Un échangeur thermique, notamment pour le transport frigorifique ou encore pour le maintien en température de chambres froides, apte à réaliser un échange entre un liquide cryogénique tel le CO2 liquide et l’air environnant l’échangeur, par exemple dans une chambre froide ou encore dans la caisse d’un camion de transport, se caractérisant en ce que l’échangeur est composé de deux tubes concentriques tels que : Le tube central est élaboré en un métal fritté ; Le tube extérieur est élaboré en un matériau à conductivité thermique élevée, par exemple du cuivre ; et en ce que Le volume annulaire de l’inter-paroi entre les deux tubes est comblé par un media à conductivité thermique élevée, par exemple par une mousse de cuivre. Figure de l’abrégé : Fig. 1A heat exchanger, in particular for refrigerated transport or for maintaining the temperature of cold rooms, capable of carrying out an exchange between a cryogenic liquid such as liquid CO2 and the air surrounding the exchanger, for example in a cold room or even in the body of a transport truck, characterized in that the exchanger is composed of two concentric tubes such as: The central tube is made of a sintered metal; The outer tube is made of a material with high thermal conductivity, for example copper; and in that the annular volume of the inter-wall between the two tubes is filled by a media with high thermal conductivity, for example by copper foam.
