Definitions
- the present invention relates to a heat exchanger for implementing the cooling of a liquid by an evaporation and adsorption method.
- the principle of such a cooling method consists in evaporating a liquid under the effect of a vacuum maintained by pumping the vapors of said liquid.
- the heat exchanger according to the invention is intended to be used in a container in the form of a refrigerating plunger or incorporated in a self-cooling beverage packaging.
- the object of the present invention is thus to allow the consumption of a drink at an ideal temperature at any place and at any time.
- US Pat. No. 4,928,495 an illustration of which is given in FIG. 1, describes a self-cooling packaging configuration 10 (presented as a can) comprising a heat exchanger 16 of flattened rectangular shape immersed in a beverage to be cooled and connected to an adso ⁇ tion device 22.
- This patent describes a schematic diagram without specifying the means of producing such a device taking into account the economic constraints linked to an application to disposable packaging.
- the exchanger 30 as described has several drawbacks. Indeed, the efficiency of the heat exchange between the evaporator and the beverage to be cooled, which conditions the rate of cooling of the beverage, depends mainly on the geometry of the exchanger. However, to obtain a satisfactory cooling efficiency, these patent applications propose to increase the size of the exchanger 30 to the maximum of what it is possible to insert into the can, namely a diameter of 50 mm for a height 100mm. The volume of the resulting exchanger is 80 ml for a volume of consumable drink of 300 ml, which represents more than 25%.
- Another drawback of the device described in the above-mentioned international applications concerns the quantity of metal necessary to produce this exchanger 30, therefore its cost price.
- the water to be evaporated contained in the exchanger for the implementation of the method of refrigeration by evaporation adso ⁇ tion must be kept under vacuum in the exchanger, and the pressure difference between the inside and the outside of the exchanger 30 imposes a significant thickness of metal constituting the walls of the exchanger.
- another drawback, linked to the particular geometry of the exchanger 30 described in these international applications consists in the obligation to use a gel to fix the coolant in the exchanger in order to avoid entrainment of the liquid by its own vapors during operation of the device.
- the objective of the present invention is to solve the drawbacks of the prior art.
- the present invention provides a heat exchanger whose geometry and arrangement makes it possible to promote the cooling rate of a drink on the principle of the evaporation of a coolant at reduced pressure.
- the geometry of the exchanger favors the establishment of large convection currents in the drink in order to ensure rapid cooling.
- This geometry also makes it possible to ensure a maximum heat exchange surface with the drink for a minimum size of the exchanger.
- Another objective of the invention is to generalize the principle of evaporative refrigeration under the effect of a vacuum to any device for refrigerating a liquid by the use of a heat exchanger according to the invention, for example used as a plunger in a container containing the drink to be cooled.

- the first wall of the cavity has a ribbed structure.
- At least part of the ribs of the first wall have a zero width inside the cavity.
- the first wall of the cavity has a section whose cross-sectional area is constant or the cross-sectional area of the first wall gradually decreases from the base to the top.
- the conical cavity has a rounded or flattened top.
- the volume of the cavity is less than 2/3 of the volume delimited by the surface of revolution enveloping said cavity.
- the cavity contains the coolant and the vapors of said liquid at a pressure below atmospheric pressure.
- the internal walls of the cavity are at least partially covered with a hydrophilic porous material.
- the coolant is water and / or water containing an additive having a saturated vapor pressure higher than that of water.
- the cavity contains a device for separating the liquid-gas state.
- at least the first wall of the cavity is composed of a thermally conductive material.
- the associated pumping means are chosen from the means consisting of an adsorbent material conditioned under vacuum, a mechanical vacuum pump, a cryogenic vacuum pump.
- the invention also relates to a self-cooling drink packaging comprising a first cavity containing a consumer drink, a second cavity contiguous to the first and forming a heat exchanger containing a coolant and its vapor, a third cavity containing pumping means. by adsorption of said vapor and means of placing said second and third cavities in communication, characterized in that the second cavity is constituted by a heat exchanger according to the invention.
- the top of the conical shape of the second cavity is oriented downward so as to create at least one convection current in the axis of the cone in the first cavity during the addition of the coolant vapor. .
- the second cavity has a volume-to-surface ratio at least two times lower than the volume-to-surface ratio of the first cavity.
- the first wall of the cavity of the heat exchanger is in contact with the drink contained in the first cavity. According to another embodiment, the first wall of the cavity of the heat exchanger is adjacent to a wall of the first cavity
- the second wall of the exchanger cavity constitutes a wall of the third cavity and integrates the means of placing said second and third cavities in communication.
- the invention also relates to a device for cooling a drink contained in a container comprising a plunger immersed in said drink to be cooled, characterized in that the plunger is constituted by a heat exchanger according to the invention.
- the exchanger is connected to the pumping means by a tube or the exchanger is integral with the pumping means, the second wall of the cavity of the exchanger being integrated into said pumping means.
- Figure 1 already described, is a diagram of a self-cooling beverage can according to a variant of the prior art
- - Figure 2 already described is a diagram of a self-cooling beverage can according to another variant of the prior art
- Figures 3a to 3c are schematic cross-sectional views of a heat exchanger according to several alternative embodiments of the invention.
- Figures 4a to 4c are schematic top views in section according to several alternative embodiments of the exchangers according to the invention;
- Figure 5 is a schematic sectional view of a particular embodiment of the heat exchanger according to the invention
- Figure 6 is a schematic sectional view of a beverage package comprising a heat exchanger according to the invention
- Figure 7 is a schematic sectional view of a refrigerant plunger comprising a heat exchanger according to the invention.
- the heat exchanger according to the invention comprises a cavity 2 containing a coolant capable of evaporating under the effect of a vacuum maintained by pumping means.
- the heat exchanger is intended to be immersed in a drink to be cooled.
- the heat exchanger according to the invention has at least a first wall 21 in contact with the beverage to be cooled and at least a second wall 22 which integrates means of communication 30 with pumping means 31 .
- the wall 21 of the cavity 2 in contact with the liquid to be cooled is of substantially conical shape such that its cross-sectional area decreases from the base to the top.
- This particular geometry of the cavity 2 of the exchanger indeed favors the establishment of large convection currents in the drink in order to ensure rapid cooling. It is important that the overall shape of the cavity is conical, in particular that its cross-sectional area gradually decreases from the base to the top. However, a straight section, which does not modify the cross-sectional area of the exchanger, can possibly be made over part of the height of the exchanger without affecting its proper functioning.
- the conical shapes covered by this definition can take several possible configurations. and concern both a pointed cone (3b) and a domed cylinder (3d).
- Figures 4a to 4d are sectional views from above of the cavity 2 of the exchanger according to the invention and the embodiments illustrated in these figures can be indifferently combined with the embodiments illustrated in Figures 3a to 3d.
- the wall 21 of the cavity 2 of the heat exchanger in contact with the beverage to be cooled may have a ribbed structure in order to increase the surface area of heat exchange between the exchanger and the drink.
- FIG. 4c illustrates an embodiment in which the first wall 21 has no ribs.
- the first wall 21 of the exchanger can be defined as being included between two surfaces of internal and external revolution (referenced i and e in FIGS. 3a to 3d) combined at the base of the cone, that is to say at the junction line with the second wall 22 of the exchanger integrating communication means 30 with pumping means.
- These surfaces i and e can advantageously consist of an assembly of cones, cylinders, toroids, spheres or any other more complex surface, produced by stamping for example.
- the apex 24 of the cone is also defined as being the point of the wall 21 furthest from the base 22 lying substantially on the axis of revolutions of the surfaces previously described.
- the top 24 of the cone 21 of the exchanger according to the invention may have a rounded shape without affecting the efficiency of the heat exchange. This rounding is motivated by a concern to avoid any incident when the empty packaging containing this exchanger is crushed.
- the exchanger according to the invention is oriented with the top of the cone down.
- the smaller heat exchange surface than the known exchangers is largely compensated by an acceleration of the convection currents produced in the axis of revolution of the cone according to a so-called "inverted chimney” effect by which all the water streams cooled at contact of the exchanger wall flow towards the axis of the cone.
- This column of cold liquid produced reinforces the pressure gradient and creates cold convection currents rising by an "inverted chimney” effect without being braked by the surface of the exchanger.
- an exchange surface of the order of 100 cm makes it possible to achieve performances equivalent to known exchangers having an exchange surface of more than 300 cm 2 with a plane geometry. Due to its geometry, the exchanger according to the invention allows the establishment of a strong axial convection current rather than the formation of cells of non-axial secondary convection currents.
- the rib cone structure makes it possible in particular to obtain a significant heat exchange surface in a limited space, specifically a limited height, which allows an advantageous application to closed beverage packages.
- the height of the ribbed cone exchanger can be limited to less than half the height of the packaging containing the drink to be cooled.
- Typical values of the geometry of an exchanger according to the invention may be the following, given without limitation but only by way of example of embodiment:
- the exchanger cavity is made of a thermally conductive material, such as steel or aluminum for example.
- the surface area of the exchanger according to the invention being reduced, the quantity of metal necessary for its manufacture is reduced, which also reduces its cost price.
- this structure allows good resistance to the external pressure exerted on the exchanger cavity by the beverage to be cooled.
- the thickness of metal constituting the cavity can therefore be reduced. In particular, a thickness of the order of 0.2 to 0.4 mm may be sufficient.
- the coolant contained in the exchanger cavity can be water, or preferably water containing an additive, for example methanol, having a high saturation vapor pressure making it possible to trigger
- the liquid only partially fills the cavity, for example half.
- the exchanger cavity contains only the coolant as well as the vapors of said liquid, that is to say that the liquid has been degassed before being introduced into the cavity.
- This degassing can be ensured, in particular, by boiling at atmospheric pressure followed by boiling by reducing pressure to a few millibars.
- the coolant is then placed in the cavity of the heat exchanger under vacuum.
- the partial pressure, in the exchanger, of gases other than the vapor of the coolant, before it is placed in communication with the pumping means is less than or equal to lmb.
- the internal walls of the cavity 2 of the exchanger are covered, at least partially, with a hydrophilic porous material, such as cellulose, a fabric or a polymer for example.
- a hydrophilic porous material such as cellulose, a fabric or a polymer for example.
- This porous layer can be bonded, for example.
- the heat exchange wall 21 is thus wetted on its internal surface, which promotes better evaporation and therefore better cooling on the exchange surface.
- a spaced-mesh fabric is used in order to promote the evaporation of the coolant in contact with the metal of the exchanger while letting the vapor of said liquid escape through the porous layer. This removes the thermal resistance of the porous layer.
- the cavity 2 of the exchanger can contain a liquid-gas separation device 50.
- This embodiment is possible due to the particular geometry of the cavity 2 constituting the exchanger according to the invention. Indeed, a large volume is available at the base of the cone, precisely near the second wall 22 integrating the connection means 30 to the pumping means 31. It is thus possible to have, inside the exchanger itself a liquid-gas separation device 50 near the opening of said connection means 30. Such a device is described below and could not be easily implemented in an exchanger of geometry known from the prior art.
- the state separation device 50 disposed in the exchanger according to the invention occupies a volume of less than 20 cm 3 .
- Such a liquid-gas state separator 50 makes it possible to separate the vapor molecules from the pumped coolant from the drops of said liquid entrained by the vapor of said liquid.
- the coolant evaporates under the effect of a vacuum initiated by a rupture of the vacuum and maintained by pumping the vapors of said liquid.
- the pumping force can be such that drops of liquid can be entrained towards the pump 31 and thus adversely affect its proper functioning. It is therefore necessary to provide a liquid-gas state separator 50 which allows the vapors of the coolant to be pumped to pass and which returns the drops of liquid to the cavity 2 of the heat exchanger.
- Such a state separator comprises a vapor deflector which consists of at least one wall forming a baffle 51 imposing one or more sudden changes of direction on the vapor flow.
- the vapor molecules have a very low mean free path, of the order of a micrometer, which means that they can change direction very quickly.
- the drops of liquid have a mass such that they are entrained by their inertia and thus separated from the gas flow. This mechanism advantageously allows a liquid-gas separation without significant slowing down of the vapor flow and therefore does not require the occupation of a large volume.
- the state separator device also comprises, in addition, a drop collector 60 making it possible to conduct the drops of liquid separated from the gaseous flow of vapor down the cavity of the evaporator 2.
- the collector 60 comprises a funnel and at the minus a drop flow tube. The funnel can advantageously contribute to forming the baffle 51 of the vapor deflector.
- the vapor deflector 51 is advantageously arranged around the communication means 30 with the pumping means 31 and the funnel of the drop collector 60 defines a solid angle which includes said communication means 30 and the vapor deflector 51.
- the drop flow tube of the collector 60 has a length greater than or equal to the pressure drop of the vapor in the baffle 51 in order to avoid the projection of drops through said flow tube.
- This pressure drop is advantageously measured in height of the volume of water. If we consider, for example, a pressure drop of the vapor V of lmb (corresponding to 1cm of water column height) the tube will be at least 1cm long.
- the state separator device further comprises a protection 55 of direct projections of drops which completes the vapor deflector 51.
- This protection 55 is arranged opposite the communication means 30 in order to avoid pollution direct pumping means 31 in particular during the initiation of the adsorption reaction.
- the pumping means 31 associated with the heat exchanger 2 according to the invention may consist of a mechanical vacuum pump, or cryogenic pumping means such as cold traps which condense the water vapors, or an air-vacuum cartridge containing reagents (desiccants) capable of triggering and maintaining the addition of the liquid.
- the implementation of cooling is therefore initiated by an implementation communication 30 of the heat exchanger 2 according to the invention with pumping means 31.
- it is the wall of the cavity forming the base 22 of the cone which comprises the means of communication 30 integrated into said wall 22.
- the invention also relates to a beverage package 10 containing a heat exchanger according to the invention as previously described.
- Such a self-cooling drink package 10 includes a first cavity 1 containing a consumer drink.
- This first cavity 1 can have the shapes and dimensions of a standardized can.
- the first conical wall 21 of the second cavity 2 is in contact with the drink contained in the first cavity 1.
- the first conical wall 21 of the second cavity 2 is adjacent to a wall of the first cavity 1.
- These walls are thus in intimate contact in order to ensure good heat transfer. They may nevertheless be made of different materials, for example the wall 21 of the cavity of the heat exchanger 2 is made of metal while the wall of the cavity 1 containing the drink is made of PET plastic (Poly Ethylene Terephthalate).
- PET plastic Poly Ethylene Terephthalate
- the second cavity 2 forming the heat exchanger has a volume-to-surface ratio at least two times lower than the volume-to-surface ratio of the first cavity 1 containing the beverage to be cooled.
- the cooling of the drink contained in the first cavity 1 is obtained by the evaporation of the coolant contained in the second cavity 2 (the heat exchanger).
- This evaporation is initiated by a depression caused in the cavity 2 of the exchanger by actuation of means for placing in communication 30 of the cavity forming the heat exchanger with pumping means 31, then this depression is maintained by pumping the vapors of said liquid.
- the self-cooling drink packaging according to the invention comprises a third cavity 3 containing pumping means 31, in this case a reservoir of desiccants capable of adsorbing the vapors of the cooling liquid according to a known physical principle mentioned previously.
- the conical wall 21 of the second cavity 2 forming the exchanger also constitutes a wall of the first cavity 1 containing the liquid to be cooled.
- the wall forming the base 22 of the cone of the second cavity 2 forming the heat exchanger also constitutes a wall of the third cavity 3 containing the desiccants, this common wall 22 integrating the means of communication 30 of said second and third cavities.
- the third cavity 3 may include actuation means 32 of the communication means 30 such as a rod triggering the opening of said communication means 30.
- the heat exchanger according to the invention can be used in a device for cooling a drink contained in an open container as a cooling plunger.
- the cooling plunger comprises a heat exchanger according to the invention with a substantially conical cavity 2 connected to pumping means 31 by means of communication connection 30 integrated into the wall 22 forming the base of the cavity 2.
- the heat exchanger is then supplied alone with its integrated communication means 30 and must be connected to suitable pumping means 31, such as a mechanical or cryogenic vacuum pump or an air vacuum cartridge containing desiccants, by a tube which can be flexible or rigid, fixed or removable.
- the cooling plunger comprises a heat exchanger according to the invention with a substantially conical cavity 2 secured to pumping means by the wall 22 forming the base of the cavity 2.
- the exchanger thermal is then provided with integrated communication means 30 and suitable pumping means 31, such as an air vacuum cartridge containing desiccants.
- the plunger thus constitutes a disposable or possibly reusable autonomous cooling device after regeneration.
