Definitions

  • the invention relates to a Flusstechnikspumpe and to a use of Flusstechnikspumpe.
  • Fluid pumps are known.
  • DE 103 47 302 Al a two-part spiral housing for a centrifugal pump is described, which is designed optimized streaming technology.
  • Such centrifugal pumps are usually driven by an electric motor, wherein the stator of the electric motor are arranged in a drying room and the rotor in a wet room. The rotor thus rotates in the wet space, which is rewound from the demanding medium to be challenged.
  • it is generally necessary to remove heat from components that heat up during operation.
  • the invention is therefore based on the object to provide a Flusstechnikspumpe that allows a corresponding heat dissipation of components in an advantageous manner, with the required additional space can be kept as low as possible.
  • the invention is further based on the object to provide a corresponding use of the Flusstechnikspumpe.
  • a Flusstechnikspumpe having in a housing a suction side S with a feed Z for the inflowing medium and a pressure side D, which leads to the discharge of the medium to be flowed, wherein the suction side S and the pressure side D Stromungstechnisch are separated by a drivable impeller, wherein in the pressure side D of the housing at least one outlet and in the supply Z at least one inlet via at least one
  • Flusstechnikskanal are interconnected, which is at least partially thermally in communication with components whose Warmth is dissipate.
  • streaming media liquids or liquid mixtures can generally be used.
  • Flusstechnikspumpe example an axial pump can be used.
  • the pressure side D which is separated from the suction side S by a drivable impeller, downstream of this impeller is downstream.
  • a partial flow of the medium to be flowed is derived and used for heat dissipation of the components, wherein the at least one outlet or the at least one entry can optionally be optimally optimized stromungstechnisch depending on the application.
  • inserts such as baffles or deflecting elements can be used.
  • the Flusstechnikskanal can be structurally versatile. It may, for example, be annular in cross-section and surrounds, for example, the electric motor which is provided to drive the liquid pump. The flow in the fluid channel is maintained by the pressure difference between the at least one outlet and the at least one inlet.
  • Evaporative cooling is realized, for example, directly within the Flusstechnikspumpe.
  • General is further advantageous that can be completely dispensed with additional Kuhlstoff.
  • Flusstechnikspumpe are arranged.
  • the Flusstechnikspumpe is usually driven by an electric motor, the electronic components that are required for operation and control of the electric motor, are heated during operation.
  • the liquid pump allows continuous heat removal from the electronic components directly into the part of the medium to be flowed, which continuously flows in the liquid channel.
  • the Flusstechnikspumpe is designed as a centrifugal pump, and a spiral housing is arranged as a housing.
  • centrifugal pumps have been preserved as fluid pumps.
  • the arrangement of the at least one outlet and the arrangement of the at least one inlet for a part of the medium to be flowed is thereby facilitated in an advantageous manner.
  • a further embodiment of the invention provides that the impeller is connected to a arranged in the wet space N rotor, which is in communication with a stator arranged in the drying chamber T, and the at least one
  • Flusstechnikskanal between the drying space T and the surrounding housing part or directly in this surrounding housing part is arranged and the components are arranged on the impeller facing away from the front side of the centrifugal pump and there are thermally in communication with the at least one Flusstechnikskanal. It is advantageous that the Flusstechnikskanal can be arranged directly in the Flusstechnikspumpe, resulting in an additional saving of space.
  • the arrangement of the components on the side facing away from the impeller of the Centrifugal pump and the local contacting with the at least one Flusstechnikskanal facilitates the heat dissipation and possibly makes it possible in a relatively simple manner the setting of evaporative cooling at this end face of the centrifugal pump by a corresponding engineering dimensioned design of the Flusstechnikskanals.
  • the subject matter of the invention is the use of the liquid pump as a coolant pump in a motor vehicle. Coolant pumps in motor vehicles must function properly over a long period of time, whereby damage to electronic components must be prevented by appropriate heat dissipation.
  • the use of the liquid pump as Kuhlwasserpumpe in a motor vehicle is thus particularly advantageous.
  • Fig. Shows the Flusstechnikspumpe in longitudinal section.
  • the liquid pump is shown in longitudinal section. It has in a housing 1 a suction side S with a supply Z for the medium to be flowed and a pressure side D, which leads to the discharge of the medium to be flowed on.
  • the suction side S and the pressure side D are stromungstechnisch separated by a drivable impeller 4 from each other.
  • an outlet Ia and in the region of the inlet Z an inlet Ib via a Flusstechnikskanal 2 are interconnected.
  • Flusstechnikskanal 2 is partially thermally in connection with components 3 whose heat is dissipate.
  • the components 3 are electronic components for operation of the liquid pump.
  • the liquid pump is designed as a centrifugal pump, wherein a spiral housing is arranged as the housing 1.
  • the impeller 4 is arranged with a rotor 5 arranged in the wet space N, which has a stator 6 arranged in the drying space T. connected.
  • the Flusstechnikskanal 2 is disposed between the drying space T and the surrounding housing part 7. It would also be possible in an advantageous manner, to arrange the Flusstechnikskanal 2 directly in this surrounding housing part 7 (not shown).
  • the components 3 are arranged on the end face of the centrifugal pump facing away from the impeller 4 and are thermally connected there to the liquid channel 2. This facilitates, for example, the formation of evaporative cooling at this end face of the centrifugal pump.
  • the entire medium to be demanded passes via the supply Z in the direction of arrow into the suction side S of the liquid pump. Due to the pressure difference between the suction side S and the pressure side D flows through a portion of the medium to be flowed through the outlet Ia the Flusstechnikskanal 2 to the entrance Ib in the supply Z, which is illustrated by the dashed arrows.
  • a kind Kuhlnikonne is advantageously generated within the Flusstechnikspumpe, with which the accumulated in the components 3 heat can be continuously removed, with the creation of additional space can be almost completely eliminated.

Abstract

La pompe à liquide présente dans un boîtier (1) un côté aspiration S avec une alimentation Z pour le fluide circulant et un côté de poussée D, qui conduit à l'évacuation pour le fluide circulant. Le côté aspiration S et le côté de poussée D sont séparés l'un de l'autre par technique d'écoulement au moyen d'un rotor (4) pouvant être entraîné. Le côté de poussée D du boîtier (1) dispose d'au moins une sortie (1a) et d'au moins une entrée (1b) au niveau de l'alimentation Z qui sont reliées l'une à l'autre par au moins un canal à liquide (2). Le canal à liquide (2) est lié thermiquement, au moins partiellement, avec des composants (3), dont la chaleur doit être évacuée. L'invention concerne également l'utilisation de la pompe à liquide en tant que pompe à eau de refroidissement dans un véhicule automobile.
