Definitions
- the invention relates to a manifold unit for one Heat exchanger with a tube block made up of several heat exchanger tubes, the manifold unit being a manifold has, in the tube wall a common longitudinal slot introduced for ends of the heat exchanger tubes to be inserted therein is.
- Such a manifold unit is known from EP 0 845 647 A1 known.
- In the collecting pipe there is an axially on both sides limited longitudinal slot introduced into the twisted by 90 ° Ends of straight flat tubes of a tube / fin block are inserted successively in a fluid-tight manner. Owing to Manufacturing tolerances especially with regard to the width of the Flat tubes and thus those parallel to the longitudinal slot of the header tube Expansion of the twisted pipe ends to be inserted there can cause problems when inserting the pipe ends into the Longitudinal slot result.
- the flat tube width for most flat tubes of the tube / fin block on the upper one Tolerance limit is or even exceeds it the longitudinal expansion of the longitudinal slot is scarce for this, so that the pipe ends in their entirety are difficult the slot can be inserted.
- the Longitudinal slot tend to be too long if the flat tube width is at or below the lower tolerance limit, which increases the risk of leaks in the longitudinal slot after sealing the inserted pipe ends.
- the invention is a technical problem of providing a collecting tube unit of the type mentioned at the beginning, in which the ends of the heat exchanger tubes one Pipe blocks reliable regardless of manufacturing tolerances fluid-tight in a common longitudinal slot of the header can be inserted.
