Abstract

A tubular heat exchanger for heating and cooling wines and turbid liqs. in the mfr. of wine is used in conjunction with a heat pump with a reversible cycle of operation. Used as a cooler, the heat exchanger is designed for refrigerant evapn. to take place in a space sepd. by only a thermally conducting wall from the liq. to be cooled. The exchanger comprises an outer tubular shell through which liq. to be treated is circulated. The shell contains an open-ended, coaxial pipe through which liq. to be treated flows. The pipe is externally sleeved from end to end, leaving a narrow, jacket space between pipe and sleeve. The space is sealed at each end by filling in the annular gap between pipe and sleeve. The jacket space has spaced inlet and outlet connections so that refrigerant fluid can circulate. Very efficient heat transfer is achieved since liq. to be treated contacts all surface of jacket through which heat transfer fluid is circulated.

Description

L'objet de l'invention concerne un dispositif d'échangeur tubulaire à détente directe pour la vinifica- tion. The object of the invention relates to a tubular exchanger device with direct expansion for vinification.

Il est destiné à assurer le réchauffement et le refroidissement pour le traitement thermique des vins et des fluides chargés. It is intended to provide heating and cooling for the heat treatment of wines and charged fluids.

Le traitement thermique des vins s'effectuait jusqu'à ce jour avec des échangeurs à plaque qui s'obs- truaient, lorsqu'on traitait des fluides chargés, c'està-dire des vins avec-pulpes de raisins et parfois des grappes. Until now, heat treatment of wines has been carried out with plate heat exchangers which clog up when dealing with charged fluids, that is to say wines with grape pulp and sometimes bunches.

On a essayé d'utiliser des échangeurs tubulaires à circulation d'eau ou de fréon, mais la répartition des calories vu les entartrages ne s'effectuait pas d'une façon suffisamment régulière pour une répartition homogène des échanges, de plus dans tous ces dispositifs il fallait utiliser deux échangeurs ou des évaporateurs, des conden- seurs et échangeurs. We tried to use tubular exchangers with circulation of water or freon, but the distribution of calories given the scaling was not carried out in a sufficiently regular way for a homogeneous distribution of exchanges, moreover in all these devices two exchangers or evaporators, condensers and exchangers had to be used.

L dispositif suivant l'invention supprime ces inconvénients et permet tout en utilisant la totalité des surfaces d'échanges concentriques de fonctionner en combinais on avec une pompe à chaleur à détente directe et in- version de cycle. The device according to the invention eliminates these drawbacks and allows while using all of the concentric exchange surfaces to operate in combination with a heat pump with direct expansion and cycle version.

Il est constitué par une enveloppe extérieure cylindrique comportant à sa partie axiale une conduite également circulaire concentrique à un carter enveloppant étanche avec espace intercalaire réduit et relié avec admission et évacuation de gaz thermique. It consists of a cylindrical outer casing comprising at its axial part also a circular pipe concentric with a sealed casing casing with reduced intermediate space and connected with admission and evacuation of thermal gas.

Sur les dessins annexés, donnés à titre d'exem- ple non limitatif, d'une des formes de réalisation de l'objet de l'invention :
La figure i montre l'échangeur vu en élévation et en coupe longitudinale. In the accompanying drawings, given by way of non-limiting example, of one of the embodiments of the subject of the invention:
Figure i shows the exchanger seen in elevation and in longitudinal section.

La figure 2 représente des variantes d'exécution de montage.  FIG. 2 represents variants of the assembly execution.

L'échangeur est constitué figure d par un élément tubulaire externe 1, à l'intérieur duquel est montée une une conduite 2 interne, sur cette conduite interne est fixé un carter étanche 3, avec poinçonnage espaceur 4, 5, de façon à centrer parfaitement le tube intérieur 2, et créer ainsi un vide intercalaire 6 cylindrique enveloppant dans lequel circule le fréon. The exchanger is constituted figure d by an external tubular element 1, inside which is mounted an internal pipe 2, on this internal pipe is fixed a sealed casing 3, with punching spacer 4, 5, so as to center perfectly the inner tube 2, and thus create an enveloping cylindrical intermediate vacuum 6 in which the freon circulates.

Le tubes 7, 8 sont soudée 9, 10, sur le tube extérieur 1, et sur le tube interne il, 12, afin de stabiliser le montage de l'ensemble et d'assurer l'entrée et la sortie du fréon ou gaz réfrigérant, tout en servant de support au tube 2. Le carter 3 est soudé sur toute sa périphérie 13, 14 afin d'assurer une étanchéité totale. The tubes 7, 8 are welded 9, 10, on the outer tube 1, and on the inner tube it, 12, in order to stabilize the assembly of the assembly and to ensure the entry and exit of the freon or refrigerant gas. , while serving as a support for the tube 2. The casing 3 is welded over its entire periphery 13, 14 in order to ensure total tightness.

Xe fluide ou liquide à traiter thermiquement circule dans le tube 1 en contact avec la totalité de la surface d'échange. Il circule également dans l'élément tubulaire 2 où il contacte également la totalité de la surface d'échange. Xe fluid or liquid to be heat treated circulates in the tube 1 in contact with the entire exchange surface. It also circulates in the tubular element 2 where it also contacts the entire exchange surface.

C'est la position concentrique de l'évapo-conden seur à l'intérieur, qui permet d'utiliser la totalité de la surface d'échange, c'èst-à-dire les faces internes 29, et externes 30, fig 1 des éléments 2 et 3. It is the concentric position of the evapo-condenser inside, which allows to use the entire exchange surface, that is to say the internal faces 29, and external 30, fig 1 elements 2 and 3.

'espace intercalaire 6 est directement relié à la pompe à chaleur à détente directe et inversion de cycle, c'est-à-dire avec émission thermique et frigorifique de fréon ou autre gaz équivalent. 'intermediate space 6 is directly connected to the direct expansion heat pump and cycle reversal, that is to say with thermal and cooling emission of freon or other equivalent gas.

Ces unités thermiques figure 2 peuvent se monter par quatre éléments 15, 16, 17, 18 en série, assemblés au moyen de coudes soudés ou démontables suivant les besoins de l'installation. These Figure 2 thermal units can be mounted by four elements 15, 16, 17, 18 in series, assembled by means of welded or removable elbows according to the needs of the installation.

Il est également possible, figure 3 de monter six éléments 19 à 24 et autres sur deux tubes 20, 21, et le fluide à traiter entre par l'admission 22 et sort par l'évacuation 23. It is also possible, FIG. 3, to mount six elements 19 to 24 and the like on two tubes 20, 21, and the fluid to be treated enters by the inlet 22 and leaves by the outlet 23.

Des jeux de chicanes 24, 25, 26, 27 et autres, placées dans chacun des tubes 20, 21, permettent de monter les six éléments en série. En modifiant le nombre et l'emplacement des chicanes, on peut obtenir plusieurs com binaisons de mise en parallèles, deux par deux, trois par trois, etc... Sets of baffles 24, 25, 26, 27 and the like, placed in each of the tubes 20, 21, make it possible to mount the six elements in series. By modifying the number and the location of the baffles, one can obtain several combinations of setting in parallel, two by two, three by three, etc ...

En supprimant les chicanes et en plaçant la sortie en 28, l'orifice 24 étant obturé, on obtient la mise en parallèle de tous les éléments. By removing the baffles and placing the outlet at 28, the orifice 24 being closed, we obtain the placing in parallel of all the elements.

Ces unités étant autonomes permettent tous les types de montages, dans lesquels le passage des fluides présente toujours un volume optimum, même s'ils sont chargés , alore que la simplicité de montage et l'économie thermique lui confèrent un maximum d'effets utiles. These units being autonomous allow all types of assemblies, in which the passage of fluids always has an optimum volume, even if they are loaded, alore that the simplicity of assembly and the thermal economy give it a maximum of useful effects.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d'être décrits. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described.
