Profile for a header of a cooler, a header having such a profile and a cooler having a header

A header of a cooler which also comprises a plurality of parallel tubes, the header including a base having a plurality of slots formed therethrough with each of the slots receiving a corresponding one of the tubes therein, the slots spaced apart from each other along the base with respect to a longitudinal direction of the header and the tubes extending through the slots with respect to a height direction of the header arranged perpendicular to the longitudinal direction thereof, the base having a cross-sectional shape between adjacent ones of the slots which comprises at least two wave troughs and at least three wave crests with the wave crests and the troughs alternatingly formed in the base with respect to a width direction of the header arranged perpendicular to the longitudinal direction and the height direction thereof, wherein from outside to inside an outer radius (R1) of a first one of the wave crests, an inner radius (R2) of the first one of the wave crests, an outer radius (R3) of a first one of the wave troughs, an inner radius (R4) of the first one of the wave troughs and a radius (R5) of a second one of the wave crests measure as follows:

• R1=1.5-3.5 mm,
• R2=2-4 mm,
• R3=1.9-5 mm,
• R4=1.9-40 mm,
• R5=3-50 mm, and wherein each of the slots extends in the width direction of the header from a first end disposed at a highest point of the first one of the wave crests with respect to the height direction of the header to a second end disposed at a highest point of a third one of the wave crests with respect to the height direction of the header with the first one of the wave crests and the third one of the wave crests forming outermost ones of the at least three wave crests with respect to the width direction of the header, and wherein the wave crests and the wave troughs are formed along an entirety of the base of the header with respect to the width direction of the header.
