Description
Panneau de refroidissement pour réfrigérateur ou congélateurCooling panel for refrigerator or freezer
Domaine de l'invention L'invention concerne un panneau de refroidissement de type roll-bond pour réfrigérateur ou congélateur permettant une amélioration de l'efficacité thermique du I o circuit frigorifique et une réduction du niveau de bruit en cours de fonctionnement.. FIELD OF THE INVENTION The invention relates to a cooling-roll type cooling panel for a refrigerator or freezer allowing an improvement in the thermal efficiency of the refrigerating circuit and a reduction of the noise level during operation.
Etat de la technique Le circuit frigorifique d'un réfrigérateur ou d'un congélateur comporte un compresseur destiné à propulser le liquide frigorigène, par exemple un hydrocarbure fluoré ou chlorofluoré, ou un alcane, et un évaporateur, généralement sous forme d'un panneau vertical, complété, dans le cas des réfrigérateurs à compartiment congélateur, d'un panneau ayant des plans horizontaux, par exemple dans le plan séparant les deux compartiments. STATE OF THE ART The refrigerating circuit of a refrigerator or freezer comprises a compressor intended to propel the refrigerant, for example a fluorinated or chlorofluorinated hydrocarbon, or an alkane, and an evaporator, generally in the form of a vertical panel. , completed, in the case of freezer refrigerators, a panel having horizontal planes, for example in the plane separating the two compartments.
L'un des modes de fabrication du panneau évaporateur consiste à réaliser le circuit du réfrigérant par la technique dite roll bond , c'est-àdire à partir de deux tôles en aluminium ou alliage d'aluminium, dont l'une est enduite, sur les zones destinées à devenir le circuit, d'une encre destinée à empêcher la soudure entre les deux tôles. Les deux tôles sont ensuite soudées par colaminage. Les zones non soudées sont alors gonflées par voie hydraulique ou pneumatique pour former le circuit, qui peut être de type biface à deux faces déformées ou de type monoface ou OSF (one side flat) à une face plane et une face déformée. One of the methods of manufacturing the evaporator panel is to perform the refrigerant circuit by the so-called roll bond technique, that is to say from two sheets of aluminum or aluminum alloy, one of which is coated, on areas intended to become the circuit, an ink intended to prevent welding between the two sheets. The two sheets are then welded by bonding. The non-welded areas are then inflated hydraulically or pneumatically to form the circuit, which can be biface type two-sided deformed or single-sided type or OSF (one side flat) to a flat face and a deformed face.
Le circuit comporte généralement une succession de canaux avec une partie descendante vers le bas du panneau et une partie remontante vers le haut du panneau, avec éventuellement en fin de circuit une zone élargie servant de bouilleur, où l'évaporation finit de s'effectuer quelles que soient les conditions extérieures. Lorsque le compresseur s'arrête, le fluide frigorigène migre du condenseur vers l'évaporateur car la haute pression dans le condenseur le pousse vers la zone de basse pression que constitue l'évaporateur, l'absence d'électrovanne ne permettant pas d'isoler la zone de haute pression de la zone de basse pression. La migration du fluide frigorigène se fait sous forme diphasique liquide/gaz et par gravité la partie liquide descend jusqu'au point le plus bas du circuit et s'y accumule. The circuit generally comprises a succession of channels with a downward portion of the panel and a upward portion of the panel, possibly with an end of the circuit an enlarged area serving as a boiler, where the evaporation ends up what whatever the external conditions. When the compressor stops, the refrigerant migrates from the condenser to the evaporator because the high pressure in the condenser pushes it towards the zone of low pressure constituted by the evaporator, the absence of solenoid valve not allowing to isolate the high pressure zone of the low pressure zone. The migration of the refrigerant is in two-phase liquid / gas and by gravity the liquid goes down to the lowest point of the circuit and accumulates there.
Le redémarrage du compresseur, notamment en l'absence d'électrovanne entre le compresseur et l'évaporateur, pousse le gaz dans une masse de liquide importante, provoquant ainsi un gargouillis audible. The restart of the compressor, especially in the absence of a solenoid valve between the compressor and the evaporator, pushes the gas into a large mass of liquid, thus causing audible gurgling.
Par ailleurs, les fabricants d'appareils électroménagers cherchent en permanence à en réduire la consommation électrique pour valoriser cet avantage auprès des 1 o consommateurs ou se conformer au cadre réglementaire. In addition, the appliance manufacturers are constantly seeking to reduce their electricity consumption in order to promote this advantage to the consumers or to comply with the regulatory framework.
La présente invention a pour but de fournir un panneau évaporateur vertical de type roll-bond pour réfrigérateur ou congélateur permettant de diminuer la consommation énergétique et de réduire le niveau sonore de l'évaporateur. The present invention aims to provide a vertical evaporator panel type roll-bond for refrigerator or freezer to reduce energy consumption and reduce the sound level of the evaporator.
Objet de l'invention L'invention a pour objet un panneau évaporateur vertical pour le refroidissement d'un réfrigérateur ou d'un congélateur, comportant un circuit de type roll bond constitué de canaux pour la circulation du fluide frigorigène avec une partie descendante et une partie remontante, dans lequel une partie au moins des canaux de la partie descendante comporte une zone d'accumulation à l'état liquide du fluide frigorigène de hauteur maximale h;, l'ensemble des hauteurs h; étant ajusté de sorte que le volume total des zones d'accumulation soit supérieur ou égal à la moitié du volume total de liquide frigorigène, et que chacune des hauteurs hi soit inférieure à 70% de la hauteur totale du canal H. OBJECT OF THE INVENTION The subject of the invention is a vertical evaporator panel for cooling a refrigerator or a freezer, comprising a roll-bond type circuit consisting of channels for the circulation of the refrigerant with a descending part and a ascending portion, wherein at least a portion of the channels of the descending portion comprises a liquid state accumulation zone of the refrigerant of maximum height h ;, all the heights h; being adjusted so that the total volume of accumulation zones is greater than or equal to half the total volume of refrigerant, and each of the heights hi is less than 70% of the total height of the H-channel.

Description de l'inventionDescription of the invention
L'invention consiste essentiellement à prévoir, dans la partie descendante du circuit évaporateur, des canaux comportant des zones d'accumulation pour le fluide frigorigène à l'état liquide de manière à éviter que ce liquide ne vienne remplir totalement les canaux du bas du circuit. Ces zones d'accumulation, présentes sur une partie seulement ou sur la totalité des canaux, permettent une répartition relativement homogène du liquide dans le panneau lors de l'arrêt du compresseur, à condition que le volume total des zones d'accumulation soit supérieur ou égal à la moitié du volume total du liquide, de sorte que le niveau sonore au redémarrage du compresseur est minimisé. The invention essentially consists in providing, in the downstream part of the evaporator circuit, channels with accumulation zones for the refrigerant in the liquid state so as to prevent this liquid from completely filling the bottom channels of the circuit. . These zones of accumulation, present on only part or on all the channels, allow a relatively homogeneous distribution of the liquid in the panel during the stop of the compressor, provided that the total volume of the zones of accumulation is superior or equal to half of the total volume of the liquid, so that the noise level at the restart of the compressor is minimized.
Il faut éviter cependant que l'accumulation de liquide empêche ou ne réduise trop le passage des gaz issus de l'évaporation du liquide, ce qui serait préjudiciable à l'efficacité thermique de l'appareil. Dans ce but, la hauteur h; du liquide dans la zone d'accumulation doit être suffisante, mais ne doit pas dépasser 70% de la hauteur totale H; du canal. However, it must be avoided that the accumulation of liquid prevents or reduces too much the passage of gases from the evaporation of the liquid, which would be detrimental to the thermal efficiency of the device. For this purpose, the height h; liquid in the accumulation zone must be sufficient, but must not exceed 70% of the total height H; of the canal.
Plusieurs modes de réalisation sont possibles pour la zone d'accumulation Celui représenté à la figure la consiste à réaliser un siphon, le canal étant recourbé vers le haut pour emprisonner un certain volume de liquide, mais en laissant un passage suffisant au gaz. Several embodiments are possible for the accumulation zone. The one shown in FIG. 1a consists in producing a siphon, the channel being bent upward to trap a certain volume of liquid, but leaving a sufficient passage to the gas.
Le mode de réalisation représenté à la figure lb consiste à prévoir sur le canal des appendices verticaux dirigés vers le bas pour l'accumulation de liquide, qui ont l'avantage de ne pas réduire la section de passage du gaz dans les canaux. Lorsque le compresseur est en marche, ces appendices permettent l'évaporation du liquide directement dans des zones éloignées des canaux, ce qui contribue à refroidir ces zones, et donc à améliorer l'efficacité thermique du circuit. L'exemple représenté à la figure 1c combine les deux modes de réalisation précédents. The embodiment shown in FIG. 1b consists in providing on the channel vertical downwardly directed appendices for the accumulation of liquid, which have the advantage of not reducing the gas passage section in the channels. When the compressor is running, these appendices allow the evaporation of the liquid directly in remote areas of the channels, which helps to cool these areas, and thus to improve the thermal efficiency of the circuit. The example represented in FIG. 1c combines the two previous embodiments.
L'exemple représenté à la figure ld montre l'utilisation de canaux de type bouilleur, c'est-à-dire des canaux larges avec des parties soudées en forme de pastilles. Le recours à ces pastilles permet d'augmenter la largeur des canaux tout en réduisant leur déformation sous l'action de pressions internes, par exemple la pression du fluide frigorigène dans certaines conditions de fonctionnement ou lors des essais pour détecter d'éventuelles fuites dans les évaporateurs avant montage du réfrigérateur ou du congélateur. Les pastilles ne doivent pas réduire trop la surface de passage du gaz lo qui s'évapore de la zone d'accumulation, ce qui entraînerait, malgré la présence de zones d'accumulation selon l'invention, une augmentation du niveau sonore. Ainsi, la somme des largeurs li des pastilles d'une zone bouilleur ne doit pas dépasser 90% de la longueur totale L de cette zone bouilleur. The example shown in Figure 1d shows the use of boiler type channels, that is to say, large channels with welded portions in the form of pellets. The use of these pellets makes it possible to increase the width of the channels while reducing their deformation under the action of internal pressures, for example the pressure of the refrigerant under certain operating conditions or during tests to detect possible leaks in the tubes. evaporators before mounting the refrigerator or freezer. The pellets must not reduce too much the passage area of the lo gas which evaporates from the accumulation zone, which would result, despite the presence of accumulation zones according to the invention, an increase in sound level. Thus, the sum of the widths li of the pellets of a boiler zone must not exceed 90% of the total length L of this boiler zone.
La figure 2 représente un exemple de panneau complet dans lequel la plupart des 15 extrémités des canaux horizontaux de la partie descendante du circuit présentent une forme en siphon, avec le canal inférieur comportant des appendices. FIG. 2 shows an example of a complete panel in which most of the ends of the horizontal channels of the downstream part of the circuit have a siphon shape, with the lower channel having appendages.
Les panneaux de refroidissement selon l'invention permettent de réduire la consommation électrique et le niveau sonore du réfrigérateur ou du congélateur. The cooling panels according to the invention make it possible to reduce the power consumption and the sound level of the refrigerator or freezer.
