Embodiment Construction

[0045] As previously described in DE198 26 881A1, the flat tube evaporator 1 (only a part in the figure) of the automobile air-conditioning equipment includes two collecting tanks 2, a flat tube (not shown) between the two collecting tanks 2 and Corrugated fins 3 arranged between flat tubes. According to this embodiment, each collecting tank 2 is formed by a slab stamped from sheet material, and the slab forms a flat collecting tank part 4 and two tunnel-shaped Collecting box part 5 (see Figure 4 and 6). Its longitudinal edge is provided with a plurality of tabs distributed over its length, which are inserted into openings in the flat collecting tank part 4 and caulked on the outside facing the flat tube. The ends are closed by caps 6 which will be described in detail later.

[0046] Formed in the flat collecting tank part 4 are a plurality of flanged holes 7 into which the flat tubes are inserted, wherein the shape of the openings of the flanged holes 7 substantially corr...

Abstract

A collecting tank (2) divides lengthwise into two chambers. Ends of pipes, e.g. flat pipes, are inserted into the base of the collecting tank, which has a tunnel-shaped collecting tank part, i.e. a level collecting tank part to form the base, and covers at each front side. - An INDEPENDENT CLAIM is also included for a motor vehicle's air-conditioning facility with a vaporizer.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a flat tube evaporator used in an automobile air conditioner. Background technique [0002] DE 198 26 881 A1 discloses a heat exchanger, in particular an evaporator, in which a collecting tank made of sheet metal is provided, which is formed from a prefabricated blank. [0003] The plate blank consists of an aluminum alloy which also forms the flat tubes, corrugated fins and side parts and other elements of the heat exchanger. The slab is first stamped from a single plate and then shaped to form a flat base (essentially flat header tank part) and a curved part (tunnel-shaped header tank part) parallel to its longitudinal sides catch. The curved member is curved according to a radius into a cylindrical surface, and the longitudinal edges of the cylindrical surface are bent so that the edges are parallel to each other and close together, and substantially perpendicular to the base. The longit...
