Abstract

The cylinder (2), containing e.g. CO2, is coaxially located within the can (9), inside a heat exchanger (4) of very thin metal sheet, repeatedly folded, concertina-style, forming a hollow sealed cylinder, star-like in cross-section, then ends being closed by circular cappings (8). Though occupying relatively little of the can volume, the exchanger offers a very extensive contact area with the drink. A spacer (7) allows it to be fitted in differently dimensioned cans. To cool the drink, the user presses on the capsule end through the cap top (4). A pin (5) in the base breaks the capsule end seal and the gas rapidly expands into the heat exchanger at e.g. about 10 degrees Celsius, venting (6) to atmosphere without contacting the drink.

Description

La présente invention concerne un dispositif autonome de refroidissement de liquide constituant un plongeur frigorigène . Le refroidissement est obtenu par la détente d'un gaz comprimé dans une capsule (2) à travers un radiateur étoilé étanche et fermé aux deux extrémités par les coupelles (8). The present invention relates to an autonomous liquid cooling device constituting a refrigerant plunger. Cooling is obtained by the expansion of a compressed gas in a capsule (2) through a sealed star radiator and closed at both ends by the cups (8).

La détente est obtenu par pression sur le bombé supérieur (4) qui entraîne la perforation de l'orifice de la capsule sur le poinçon (5) et libère le gaz qui circule dans le radiateur étoilé réalisé en tôle métallique de très faible épaisseur et qui présente une très grande surface d'échange. The expansion is obtained by pressing on the upper crown (4) which causes the perforation of the orifice of the capsule on the punch (5) and releases the gas which circulates in the star radiator made of sheet metal of very small thickness and which has a very large exchange surface.

A titre d'exemple, un radiateur tel que représenté à l'échelle 1 occupe un volume de 15 centilitres pour une surface d'échange thermique de 15 dm2
Le gaz libéré par une détente rapide sort de la capsule à une température négative (-10"C pour le CO2 par exemple) et refroidit donc le radiateur de manière quasi instantanée. II s'échappe ensuite vers l'extérieur en remontant autour de la capsule pour aboutir à l'orifice d'évacuation (6).For example, a radiator as shown in scale 1 occupies a volume of 15 centilitres for a heat exchange surface of 15 dm2
The gas released by a rapid expansion leaves the capsule at a negative temperature (-10 "C for CO2 for example) and therefore cools the radiator almost instantaneously. It then escapes towards the outside by going up around the capsule to lead to the discharge orifice (6).

Ce plongeur frigorigène, peut être serti dans une canette (9) comme représenté par les figures 2 et 3. Il comportera à sa partie inférieure, une cale
(7) pour l'ajuster parfaitement à la hauteur de la canette. Cette cale est réglable selon la capacité de liquide consommable envisagée. This refrigerant plunger can be crimped into a can (9) as shown in Figures 2 and 3. It will have a shim at its bottom
(7) to adjust it perfectly to the height of the bobbin. This wedge is adjustable according to the capacity of consumable liquid envisaged.

Claims (2)
