A portable cooling system for use in conjunction with child carriages incorporating a reservoir of ice and a water pump that directs chilled water through a dehumidifying radiator located in an air handler assembly is herein disclosed. The water continues to circulate through two (2) cooling radiators and returns to the ice and water reservoir by gravity. An electric fan blows air through the radiators where it is dehumidified by the first radiator and cooled by the next two (2) radiators. The air then continues through the air handler wherefrom it is directed toward the child through a flexible duct. A rechargeable battery system is used to power the operation of both the pump and the fan through separate switches. Such an arrangement allows the user to run just the fan for ventilation if cooling is not needed. The cooling system is carried upon the rear of a baby carriage in a stable manner.
