This is a portable cooling system designed to attach to a child's carriage. It uses a reservoir of ice water, a pump, and a fan to circulate chilled water through radiators and blow air over them. The air is first dehumidified and then cooled before being directed towards the child through a flexible duct. The system, powered by a rechargeable battery, allows the user to run just the fan or both the fan and cooling.
Why it matters: Since 2009, portable battery technology has advanced significantly, offering lighter, longer-lasting power. Miniaturized, more efficient pumps and fans are also available, improving feasibility for portable cooling.
