Abstract
A method for cooling IR emitters in a heating device for warming preforms before processing them in a stretch blow or blow molding device. IR emitters are arranged on at least one sidewall of the heating device parallel to the transport direction of the preforms, with at least one back reflector arranged on the side of the IR emitters facing away from the performs. The preforms to be warmed include a mouth region and a longitudinal axis and the mouth region is cooled with a first coolant flow. An almost vertical second coolant flow passes between the IR emitters and the at least one back reflector, this second coolant flow being at least partially fed by the almost horizontal first coolant flow and/or is united with the almost horizontal first coolant flow. A heating device and cooling device are also provided.
