Description

Wärmeaustauscher heat exchangers
Die Erfindung betrifft einen Wärmeaustauscher für Fluide, insbesondere Hydrauliköl, mit einem Gehäuse, in dem Fluidka- näle und Kühlmittelkanäle einander abwechseln, wobei das Ge¬ häuse einen Einlaß für heißes Fluid, einen Auslaß für gekühl¬ tes Fluid sowie einen Einlaß und einen Auslaß für das Kühlmit- tel aufweist.The invention relates to a heat exchanger for fluids, in particular hydraulic oil, with a housing in which fluid channels and coolant channels alternate with each other, the housing having an inlet for hot fluid, an outlet for cooled fluid and an inlet and an outlet for having the coolant.
Derartige Wärmeaustauscher sind vielfach in Verwendung. Der Nachteil der bekannten Wärmeaustauscher besteht darin, daß das heiße Fluid, z.B. Hydrauliköl, vor dem Eintritt in den oder nach dem Austritt aus dem Wärmeaustauscher durch eine ge- sonderte Filtereinrichtung geführt werden muß, um Fremdkörper aus dem Fluid zu entfernen.Such heat exchangers are often in use. The disadvantage of the known heat exchangers is that the hot fluid, e.g. Hydraulic oil must be passed through a separate filter device before entering or exiting the heat exchanger to remove foreign matter from the fluid.
Die Erfindung zielt darauf ab, diesen Nachteil zu vermei¬ den und auf konstruktiv einfache Weise sauberes gekühltes Flu¬ id zu erzielen. Ein gemäß der Erfindung ausgebildeter Wärme- austauscher der einleitend angegebenen Art zeichnet sich da¬ durch aus, daß im Gehäuse ein zentraler Zylinderraum vorgese¬ hen ist, der an seinem Umfang durch einen Filter ausgekleidet ist, über welchen das einströmende heiße oder das ausströmende gekühlte Fluid in die Fluidkanäle eintritt bzw. aus den Fluid- kanälen austritt.The invention aims to avoid this disadvantage and to achieve clean, cooled fluid in a structurally simple manner. A heat exchanger of the type described in the introduction is characterized in that a central cylinder space is provided in the housing, which is lined at its circumference by a filter, via which the hot or the outflowing cooled fluid flows enters the fluid channels or emerges from the fluid channels.
Auf diese Weise wird erreicht, daß das heiße Fluid unmit¬ telbar vor oder nach seiner Kühlung gefiltert wird, wodurch sich eine dem Wärmeaustauscher vor- oder nachgeschaltete ge¬ sonderte Filtereinrichtung erübrigt . Bei einer bevorzugten Ausführungsform der Erfindung ist das Gehäuse durch ein im wesentlichen parallelepipedisches Pa¬ ket aus horizontale Fluidkanäle und Kühlmittelkanäle begren¬ zenden Platten gebildet ist, die von dem Zylinderraum und von einem Kühlmittelkanal sowie einem Fluidaustrittskanal durch- setzt sind. Alternativ ist das Gehäuse durch einen zylindri¬ schen Körper gebildet, in welchem die Fluidkanäle und die Kühlmittelkanäle in Form von Kränzen axial verlaufender Kanäle ausgebildet sind, wobei ein oder mehrere äußere Kränze von Fluidkanälen an der fluideintrittseitigen Gehäusestirnseite ausmündet und an der Oberseite des Zylinderraumes eine Umlen¬ kung von dem inneren Fluidkanalkranz zu dem äußeren Fluidka- nalkranz bzw. den äußeren Fluidkanalkränzen vorgesehen ist.In this way, it is achieved that the hot fluid is filtered immediately before or after its cooling, whereby a heat exchanger upstream or downstream ge special filter device is unnecessary. In a preferred embodiment of the invention, the housing is formed by a substantially parallelepipedic packet of horizontal fluid channels and coolant channels. The plates are defined by the cylinder space and by a coolant channel and a fluid outlet channel. are set. Alternatively, the housing is formed by a cylindri¬'s body in which the fluid channels and the coolant channels are formed in the form of rings of axially extending channels, wherein one or more outer rings of fluid channels at the fluid inlet side housing end side opens and at the top of the cylinder chamber a Umlen ¬ kung of the inner fluid channel ring to the outer Fluidka- nalkranz or the outer fluid channel wreaths is provided.

Der zentrale Zylinderraum 7' ist an seiner Innenseite mit einem Filterkörper 13' ausgekleidet, durch welchen das un- ter Druck einströmende heiße Fluid radial in die außerhalb des6, fluid ducts 4 ', 4 "and coolant ducts 5' arranged in a radial direction alternate with one another, the central cylinder chamber 7 'being lined on its inner side with a filter body 13', through which the lower Pressure inflowing hot fluid radially into the outside of the
Filterkörpers 13' axial verlaufenden Fluidkanäle 4' strömt, welche an der Gehäuseoberseite in die radial auswärts liegen¬ den Fluidkanäle 4" übergehen, die über die untere Gehäuse¬ stirnseite ausmünden. Auch bei der Ausführungsform nach den Fig. 5 und 6 kann die Strömungsrichtung des zu kühlenden Fluid und des Kühlmittels umgekehrt werden.Filter body 13 'axially extending fluid channels 4' flows, which on the upper side of the housing in the radially outwardly lie¬ the fluid passages 4 "merge, which open out via the lower Gehäus¬ front side also in the embodiment of FIGS. 5 and 6, the flow direction of be reversed to be cooled fluid and the coolant.
