  • Heat exchanger
    Patent number: 7240507
    Abstract: A heat exchanger for cooling a liquid comprising a cavity (2) containing a refrigerating liquid capable of evaporation under the effect of a depression maintained by a pump. The cavity includes at least a first wall (21) in contact with the liquid to be cooled, the first wall (21) being substantially conical such that its cross-sectional surface tapers from the base towards the top, and at least a second wall (22) forming the base of the conical shape and incorporating communication (30) between the cavity (2) of the exchanger and the pump.

  • Self-refrigerating packaging and associated actuation device
    Patent number: 7213401
    Abstract: The invention relates to self-refrigerating beverage packaging comprising: a first cavity (10) which contains a beverage; a second cavity (20) which forms a heat exchanger and which contains a refrigerating liquid and the vapour thereof; a third cavity (30) which contains means for the adsorption pumping of said vapour and means of connecting (40) the second cavity with the third cavity. The inventive packaging is characterised in that the second and third cavities are provided with a common wall (25) comprising the built-in connection means, and in that said connection means (40) comprise a check valve (42) which can withstand pressure exerted on the side of the second cavity and which opens under the effect of a force exerted on the side of the third cavity.

  • Adsorption refrigerating device
    Patent number: 6895779
    Abstract: An adsorption refrigeration device having an evaporator containing a refrigerant liquid that evaporates under the effect of a depression and an adsorbent capable of fixing the vapors (V) of the refrigerant liquid. The adsorbent is in contact with a heat exchanger containing a cooling liquid that evaporates when the adsorbent (205) is heated, and the heat exchanger includes at least one aperture to the outside atmosphere constituted by at least one hole that limits the flow rate of the vapor of the cooling liquid.
