Constructed inside an insulated 10-quart cooler, the system features a removable 6-can carrier secured with Velcro straps, an acrylic flow baffle, and two 12V submersible pumps delivering a combined nominal flow of 480 L\/hr powered by a rechargeable lithium-ion battery pack. To remove 222.6 kJ of heat at an average rate of 742 W, the pumps circulate a salted ice-water bath around the cans at a local fluid velocity of 0.30 m\/s. While preliminary modeling predicted a 4.43-minute cooling time under a constant 18\u00b0F (-7.78\u00b0C) bath assumption, the final analysis incorporates a water-to-ice convection check and a 2.13\u00b0C coolant temperature rise. Accounting for finite heat transfer between the returning coolant and the 1.34 kg ice bed yields an average effective bath temperature of -6.20\u00b0C (-7.27\u00b0C supply, -5.14\u00b0C return), resulting in a revised, realistic cooling time of 4.81 minutes that satisfies the five-minute performance requirement. <\/span><\/p>\n<p>Project Link: https:\/\/drive.google.com\/drive\/folders\/1K26ZO8YseiAfUnmdqRIsGqXqOvhLj0U6?usp=drive_link<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This project evaluates the design and thermal calculations for a portable beverage cooling device engineered to chill six 12-oz cans from 85\u00b0F (29.44\u00b0C) to 40\u00b0F (4.44\u00b0C) in under five minutes.
