Technology Highlights

• The invention offers a light, portable, and practical device for cooling beverages directly or indirectly in outdoor settings.
• The invention provides a self-cooling device in the form of a mug or jug, designed to contain a beverage poured from a separate container.
• The invention takes the form of a cylindrical sleeve with a base and houses a miniaturized scroll compressor, which is controlled by a manually operated on/off switch.
• The invention includes a flexible, adjustable sleeve that accommodates containers of various volumes and sizes.
• The invention provides a rechargeable battery as a power source, which can be recharged when the energy level is low.
• The invention protects an internal network of capillaries while allowing efficient heat exchange from the beverage container to the refrigerant, via an expansion valve feeding into the capillary network.
• The invention absorbs heat energy indirectly from the beverage through the capillary network embedded in the inner cylindrical wall of the container.
• The invention regulates the heat exchange process through multiple temperature-gauging devices placed inside the container walls and offers a large surface area to maximize heat absorption from the beverage.
• The invention improves refrigerant efficiency by cooling it before it undergoes another heat exchange cycle through the capillary network.
• The invention monitors the temperature of the beverage using internal sensors and sends real-time readings to a microprocessor, which controls the motor accordingly.
• The invention detects the boundary between the cooled beverage and ambient air, and uses a control sensor to continuously record the ambient air temperature.
• The invention determines energy expenditure based on input from multiple vertical sensors that correspond with the control sensor to optimize performance.
