Abstract: A condensate separator for separating condensate from a gas stream, the condensate separator may include a housing having a condensate drain at a bottom end, a swirl generator provided at an inlet end of the housing, the swirl generator placing the gas stream in a rotational movement, and an impact element situated downstream from the swirl generator.

Abstract: A heat exchanger may include a plurality of tubes each having longitudinal ends and held at the longitudinal ends in a collector. The collector may include a first element and a second element. The first element may include a plurality of passage openings for receiving the plurality of tubes. The second element may include at least one slot extending in a longitudinal direction of the second element. The heat exchanger may also include at least one attachment flange including two inner lips facing toward the at least one slot, a first duct section communicating with the at least one slot, and a second duct section angled relative to the first duct section by an angle ?. The two inner lips may bear on and be calked against an edge of the at least one slot.
