Definitions
- the invention relates to an evaporator with a refrigerant channel arrangement and Intake pipe connection point, into which an intake pipe opens and fixed there liquid-tight is.
- Document DD 255 199 discloses such a device.
- the suction pipe is at the suction pipe connection point liquid-tightly connected to the evaporator by means of a welded connection.
- the so-called tungsten inert gas welding is used as the welding process applied, the welding process due to the two to be welded Components, in particular by the on the evaporator board as a result of the manufacture of Intake manifold connection by means of flared tolerance and material thickness fluctuations is not controllable as an automatic process.
- the invention has for its object in an evaporator according to the preamble of claim 1 with simple constructive measures the disadvantages of the state technology avoidable, automatable connection between the intake manifold and to provide the intake manifold connection point.
- This object is achieved according to the invention in that the intake manifold in the intake manifold connection point is introduced and this is largely due to non-cutting shape is adapted to the contour of the suction pipe, which by soldering with the Intake pipe connection point is connected liquid-tight.
- the solution according to the invention is used to connect the intake manifold connection point with the intake manifold is an automated manufacturing process that is unaffected by a worker possible because by adapting the intake manifold to the contour of the Suction tube a defined and uniform soldering gap is generated between the two, which by capillary action the necessary for connecting the two connecting elements Solder automatically pulls to the connection point.
- This ensures that the intake manifold connection point is connected to the intake manifold free of voids and liquid-tight is, so that the connection between these two components with high process reliability is afflicted.
- the solution according to the invention is extreme Inexpensive, but with a very high probability tight connection provided between the suction pipe and the suction pipe connection point.
- two plastic material deformations by the non-cutting shaping are generated, which are at least approximately opposite each other at the intake manifold connection point.
- plastic material deformations in an evaporator with one between two connected circuit board extending refrigerant channel arrangement are opposite.
- a board-like evaporator is particularly expedient if, after a last preferred embodiment of the subject of the invention is provided, that the board-like evaporator is produced by the roll bond or the Z bond process is.
- a section of an evaporator board 10 is shown, which by Welding is formed by two sheet aluminum plates 11 and 12 of equal area, in which, in the present case, one produced by the so-called roll bond process Refrigerant channel arrangement 13 is introduced.
- This has an intake manifold connection point 14, which can be expanded by e.g. by a so-called section by section Thorning of the refrigerant channel 13 produced in the roll bond process in the edge region of the evaporator board 10 is generated, the generated intake manifold connection point 14 has a lens-like cross section.
- the intake manifold connection point 14 is set back from the free edge of the evaporator board 10 with a depth stop 15 equipped, which expanded by the length I of the intake manifold 14 Refrigerant channel 13 is formed and which for introducing a section shown, made of aluminum suction tube 16 is used.
- the suction pipe 16, its insertion depth into the intake manifold connection point 14 through the depth stop 15 is limited, is fixed to the evaporator board 10 by soldering, whereby before the soldering process that was originally carried out after the expansion process with an oval Cross section equipped intake manifold connection point 14 by an embossing process the outer contour of the suction pipe 16 is adapted.
- the aluminum boards 11 and 12 plastically deformed by the non-cutting shaping by means of embossing, whereby the plastic material deformation lies in the plane of the evaporator board 10.
