Abstract

The invention relates to a highly efficient heat exchanger which can be formed by a single length, made of corrugated stainless steel tube, avoiding any welding or connection in contact with the treated liquid. It consists of a corrugated tube 1 made of thin stainless steel formed according to the use envisaged and of a single and unique length. Profiles 2 maintain the optimum separation between turns. The end of the four profiles is welded to a tube portion 3 allowing possible fixing at the bottom of a vat or a better penetration into the must if it is desired to place the heat exchanger after filling the vat. Connectors 4 provide the hydraulic link of the heat exchanger. The heat exchanger according to the invention is particularly intended for controlling fermentation or heat-treatment temperatures of juices or must of fruit, such as grapes for example.

Description

DESCRIPTION
Echangeur permettant le chauffage ou le refroidissement direct de vin cu de moût contenu dans des cuves.DESCRIPTION
Exchanger allowing the direct heating or cooling of wine or must contained in tanks.

La présente invention concerne un échangeur à haut rendement monotube onduleux destiné à refroidir ou réchauffer les vins ou moûts contenus dans une cuve de vinification. The present invention relates to a high-efficiency wavy single-tube exchanger intended to cool or reheat wines or musts contained in a vinification tank.

Traditionnellement, les échangeurs sont cc stitués de plaques d'acier inoxydable, profilées ou embouties, de diverses formes ; soit des tubes lisses soudés bout à bout puis enroulés ou soudés sur des collecteurs. Ces échangeurs, outre le nombre important de soudures présentant un risque de fuite évident dans la cuve, sont lourds et encombrants, pour un coefficient d'échange relativement faible et un coût élevé. Traditionally, exchangers are made up of stainless steel plates, profiled or stamped, of various shapes; either smooth tubes welded end to end and then wound or welded on manifolds. These exchangers, in addition to the large number of welds presenting an obvious risk of leakage in the tank, are heavy and bulky, for a relatively low exchange coefficient and a high cost.

La conception de l'échangeur suivant l'invention permet de remédier à l'en- semble de ces problèmes tout en apportant un matériel plus performant et moins onéreux. The design of the exchanger according to the invention makes it possible to remedy all of these problems while providing more efficient and less expensive equipment.

L'échangeur selon l'invention est constitué et fabriqué à partir d'un tube (1) rigide onduleux en acier inoxydable formable à la main. The exchanger according to the invention is formed and manufactured from a rigid wavy tube (1) of stainless steel formable by hand.

Le tube (1) sur la figure 1 est d'une seule et unique longueur afin de constituer un échangeur sans soudure ni raccord, évitant ainsi tout risque de fuite de fluide caloporteur dans la cuve en traitement. The tube (1) in Figure 1 is of a single length to form a heat exchanger without welding or fitting, thus avoiding any risk of leakage of heat transfer fluid in the tank under treatment.

La longueur et le diamètre du tube (1) sont calculés de façon à assurer la puissance désirée de l'échangeur ainsi formé : figure 1. The length and diameter of the tube (1) are calculated so as to ensure the desired power of the exchanger thus formed: Figure 1.

La faible épaisseur du métal constituant le tube (1) figure 2 est de l'or- dre de deux dixièmes de millimètre. Cette faible épaisseur accroit dans de fortes proportions le transfert thermique de l'échangeur, et contribue au faible poids du matériel permettant une mise en oeuvre aisée. The small thickness of the metal constituting the tube (1) in FIG. 2 is of the order of two tenths of a millimeter. This small thickness greatly increases the heat transfer of the exchanger, and contributes to the low weight of the material allowing easy implementation.

Sur la figure 2 l'aspect onduleux (2) dont le profil se rapproche d'une sinusoide, améliore les performances par une augmentation importante des turbulences à l'intérieur et à l'extérieur du tube. De ce fait, le coefficient d'échange à débit d'eau égal est supérieur à celui d'un tube lisse de même surface d'échange. L'aspect onduleux permet le cintrage et la mise en forme, sans outillage spécialisé ou coûteux. In Figure 2 the wavy appearance (2) whose profile is close to a sinusoid, improves performance by a significant increase in turbulence inside and outside the tube. As a result, the exchange coefficient at equal water flow rate is greater than that of a smooth tube with the same exchange surface. The wavy appearance allows bending and shaping, without specialized or expensive tools.

La forme de l'échangeur peut être obtenue par un enroulement sur une "forme" circulaire ou elliptique suivant le dessin et les dimensions de l'ouverture de visite de la cuve équipée. The shape of the exchanger can be obtained by winding on a circular or elliptical "shape" according to the drawing and the dimensions of the inspection opening of the equipped tank.

Sur la figure 1 des profilés en acier inoxydable (2) soudés ou assemblés par rivetage, assurent à l'échangeur la rigidité suffisante et nécessaire à l'utilisation prévue. Ces profilés assurent outre la rigidité de l'ensemble, l'écartement constant (e) entre chaque spire. Cet écartement, pour des raisons de convection autour du tube doit être égal à une fois et demie le diamètre nominal (DN) du tube (1). In FIG. 1, stainless steel profiles (2) welded or assembled by riveting, provide the exchanger with sufficient rigidity and necessary for the intended use. These profiles ensure, in addition to the rigidity of the assembly, the constant spacing (e) between each turn. This spacing, for reasons of convection around the tube must be equal to one and a half times the nominal diameter (DN) of the tube (1).

L'extrémité des quatre profils assemblés par rivetage est soudée ou ri vee sur une portion de tube (3) figure 1 permettant la fixation en fond de cuve ou une meilleure pénétration dans la masse du moût si l'on désire placer l'échangeur après le remplissage dans la cuve, dans le cas de vin rouge par exemple. The end of the four profiles assembled by riveting is welded or ri vee on a portion of tube (3) figure 1 allowing the fixing at the bottom of the tank or a better penetration in the mass of the must if one wishes to place the exchanger after filling in the tank, in the case of red wine for example.

Des pièces de raccordement (4) soudées ou assemblées par raccords mécaniques et joints toriques assurent et permettent le raccordement au réseau d'alimentation hydraulique de l'échangeur.  Connection pieces (4) welded or assembled by mechanical connections and O-rings ensure and allow connection to the hydraulic supply network of the exchanger.
