A cooling ring for a film blowing line, with a ring chamber, which at a peripheral edge forms an outlet gap for the delivery of a cooling medium onto the film bubble (14) and is divided by radial cross members (24) into several segments (34), and with fittings (30, 32) for homogenizing the flow of the cooling medium in the individual segments (34), wherein the fittings have deflector plates (30), which are disposed obliquely to the radial direction and deflect a portion of the cooling medium from the central regions of the segments (34) to the cross members (24).
