Abstract: An assembly for cooling a liquid inside a portable container. According to some implementations the portable container has a heat exchanger assembly disposed therein with the heat exchanger assembly including a coolant pre-cooling assembly. According to the same or other implementations a tortuous coolant fluid passage that runs through at least a portion of the heat exchanger assembly includes one or more constrictions for controlling the evaporation temperature of the coolant along the length of the passage.

Abstract: A liquid container designed to include an autonomous selective cooling device and cooling device applicable to the liquid container. The cooling device includes a heat exchanger comprising a first body with a cavity, a second body inside the cavity, a fluid passage formed between an outer surface of the second body and the surface of the cavity, and some means for causing a cooling fluid to flow while expanding along fluid passage up to an exhaust duct of the second body. A container comprises a cavity for a liquid, a first filling opening provided with a first closing element and a second opening with a first coupling element where a second coupling element is coupled to the second coupling element being formed at an extension of a second closure cap and connected to the heat exchanger, in such a way that the closure cap closes the second opening of the container and the heat exchanger is housed in the cavity of the container and in contact with the liquid contained in it.

Abstract: An assembly for cooling a liquid inside a portable container. According to some implementations the portable container has a heat exchanger disposed therein with a cooling medium cartridge at least partially surround by the heat exchanger. According to other implementations a rechargeable cooling medium cartridge may be attached to an end of the portable container with an exhaust port of the rechargeable cartridge being in fluid communication with an inlet to a heat exchanger disposed inside the portable container.
