Definitions

  • the present invention relates to a housing of a dryer for a cooling medium in a cooling medium circuit, in particular an air conditioning system of a vehicle, and to a dryer for a cooling medium in a cooling medium circuit, also in particular an air conditioning system of a vehicle.
  • Dryer housing of the type in question are well known in the art and find application in dryers, which serve to filter out impurities and moisture from a cooling medium and absorb. Frequently, such dryers are used for cleaning the cooling medium in air conditioning systems of a vehicle to absorb the moisture in the system by means of a desiccant.
  • the DE 10 2005 023 103 A1 shows a dryer of an air conditioner of a vehicle, in which a housing is filled with a desiccant.
  • the housing is formed from a first housing part and a second housing part, which are fluid-tightly connected to one another via a welding method.
  • the first housing part has two openings, to which connecting elements for connection to media lines are attached or welded.
  • a problem with such dryer housings is that leaks can occur, in particular at the welds or solder joints, and thus the functionality of the dryer can not be guaranteed.
  • the housing in the region of the joints (welds and solder joints) disadvantageous material properties in terms of toughness and ductility so that also a failure of the dryer due to cracking in the housing is possible.
  • a housing of a dryer for a cooling medium in a cooling medium circuit in particular an air conditioning system of a vehicle, with the features of claim 1 and by a dryer for a cooling medium in a cooling medium circuit, in particular an air conditioning system of a vehicle, having the features of claim 12 solved.
  • a housing of a dryer for a cooling medium in a cooling medium circuit in particular a climalange of a vehicle provided, comprising a first and a second housing portion, which are each formed in a hollow cylinder, and a connection area which is arranged between the first and the second housing portion and hollow cylindrical is formed, wherein the connecting portion has at least one radial opening, and wherein the housing is formed as a one-piece flow press.
  • the housing is expediently used as a dryer housing for a cooling medium in a cooling medium circuit, which may be the cooling medium circuit of a climate-controlled vehicle or motor vehicle.
  • the housing has a first and second housing portion, which are each formed in a hollow cylinder.
  • connection area is likewise hollow-cylindrical.
  • first and the second housing portion and the terminal portion may be arranged concentrically with each other, so that they are arranged parallel to a longitudinal axis of the housing.
  • the cross-sectional configurations of the first and second housing regions and of the connection region can be configured as desired, for example, round or angular or polygonal.
  • the second housing portion may be closed at its end opposite the first housing portion. This can be done indirectly via additional closure elements or directly by forming the second housing region as a closed-end tubular body (ie with a closed bottom). The same can apply to the first housing area.
  • the connection region arranged between advantageously has at least one radial opening.
  • the opening can thus be formed radially or laterally or on the circumference of the connection region or transversely, preferably perpendicularly, to the longitudinal axis of the housing.
  • the housing is designed as a one-piece extruded part.
  • the housing is integrally or integrally formed of a preferably homogeneous material.
  • the housing according to the invention has no joining areas of different elements, as is known in the case of the prior art.
  • a tubular or rod-shaped housing is provided, which is formed as a one-piece body joining edge or area-free.
  • connection region has a connection section projecting radially outwards, in which the at least one opening is provided.
  • the connection section can thus be expediently designed as a projection which protrudes radially or laterally beyond the outer circumference of the first or second housing region or connection region and which surrounds the at least one opening.
  • the opening can thus be provided in the outwardly projecting connection section.
  • connection region has two radial openings.
  • the two openings may be formed as an inlet and outlet opening.
  • the two openings are formed in the same connection section.
  • two outwardly projecting terminal portions may be provided, each housing an opening.
  • the Cross-sectional shape of the openings can be designed arbitrarily, for example, rectangular or polygonal. Preferably, however, this is round, in particular circular.
  • connection section has a connection surface for arrangement on a capacitor, which is preferably concave.
  • the connection surface advantageously has a round, preferably circular, surface configuration with a cross-sectional shape that is preferably constant along the longitudinal axis of the housing.
  • the wall thickness of the first housing portion is greater than the wall thickness of the second housing portion. This makes it possible that the first housing portion can be at least partially subjected to an exciting forming, for example, to provide a thread for a closure element.
  • the first and second housing regions preferably have a round, preferably circular, cross-sectional configuration.
  • the first and second housing region can thus expediently have a substantially rotationally symmetrical cross-sectional shape.
  • the connection area can also have a round or circular interior configuration. However, on the outside or surface of the radially outwardly projecting connection portion is advantageously provided.
  • the first and second housing portion on the same outer diameter.
  • the first and second housing regions constitute a substantially tubular or rod-shaped body.
  • the inner diameter of the first and second housing region does not have to be identical, since the first housing region expediently has a greater wall thickness and thus has a smaller inner diameter than the second housing region.
  • the first housing portion has an engagement portion, with which a closure element can be brought into engagement.
  • the engagement section is preferably provided on the inside or surface of the first housing region, preferably on its end region facing away from the second housing region.

  • the sealing section is expediently provided on the inside or surface of the first housing region on the side or end facing the second housing region. This may have any cross-sectional configuration, but is advantageously rotationally symmetrical about the longitudinal axis of the housing.
  • the sealing portion may have an (inner) radius which is smaller than the (inner) radius of the engagement portion, so that the first housing portion, starting from its end facing away from the second housing portion, tapers in the direction of the second housing portion.
  • connection region has an inwardly projecting abutment section, on which a closing element can be brought into abutment in abutment.
  • the contact portion may advantageously be circumferentially formed on the inner circumference of the end element and thus rotationally symmetrical as an annular projection.

  • the dryer further comprises a closure element comprising a filter to filter the cooling medium supplied to the dryer.
  • the closing element can in particular close an open end of the first housing area.
  • connection region has two lateral openings which are separated from one another by the built-in terminating element, which has a structure correspondingly separated by the filter.
  • an inlet opening arranged adjacent to the first housing area can supply the cooling medium to the filter of the closing element, after which it flows into the second housing area or one of the second housing area adjacent region of the connection region, at which the outlet opening is provided.
  • a production method for a housing of a dryer for a cooling medium in a cooling medium circuit comprising the steps of providing a workpiece blank, and pressure forming by extrusion of the workpiece blank such that the workpiece blank is a one-piece unit of a first and a second housing portion and an intermediate terminal portion is formed with at least one radially outwardly projecting terminal portion.
