• 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.
• appropriate Kuhlaggregate be arranged, however, increase the space for the Flusstechnikspumpe disadvantageously.
• the invention is therefore based on the object to provide a method for removing heat from components of a Flusstechnikspumpe, for the implementation of which only a relatively small additional space is required.
• the invention is further based on the object to provide a device for carrying out the method and a corresponding use of the device.
• the object underlying the invention is achieved by a method for removing heat from components of a Flusstechnikspumpe in a housing a suction side S with a supply Z for the medium to be flowed and a pressure side D, which leads to the removal of the medium to be flowed , wherein the suction side S and the pressure side D Stromungstechnisch are separated by a drivable impeller, in which in the range of
• Components is thermally connected and in which the medium to be streamed in the region of the components is at least partially evaporated and the removal of heat from the components is thus realized by evaporative cooling.
• the current media used are liquids or mixtures of liquids.
• 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.
• the flow in the channel is maintained by the partially vaporized flow medium.
• the heat accumulated in the components can be dissipated in a relatively simple manner by evaporative cooling, which can be almost completely dispensed with the creation of additional space, as provided only a small additional space for the at least one channel must become.
• the required additional space is thus almost meaningless in relation to the total space requirement of the liquid pump.
• the at least one channel can be realized constructively in different ways. It can be arranged, for example, as an annular space around the electric motor, which drives the liquid pump in its interior.
• Components are arranged, which are arranged as electronic components for operating the Flusstechnikspumpe.
• 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 method allows a continuous heat removal from the electronic components directly into the part of the medium to be flowed, which flows continuously in the liquid channel and partially evaporated by the heat.
• the evaporative cooling realized in the process is extremely effective, which benefits the protection of the electronic components.
• the supply and the discharge of the part of the medium to be streamed takes place at least partially in opposite directions in the at least one channel.
• “contrary” is meant “counteracted”.
• Within the at least one channel there are thus two oppositely directed directions of flow. In one flow direction, part of the medium to be flowed is transported to the components to be cooled. In the opposite direction of the second flow, the part of the medium to be streamed is transported away and then returns to the pressure side D of the liquid pump.
• the method can be carried out with a channel designed as a channel strand, thereby minimizing the required additional installation space.
• a further preferred embodiment of the invention provides that the removal of heat from components of a centrifugal pump arranged as a liquid pump Evaporative cooling takes place, wherein in the region of the flow cross-section II of the pressure side D, a part of the medium to be flowed is diverted from the spiral housing arranged as a housing.
• centrifugal pumps have been preserved as fluid pumps. Since the flow cross-section in the spiral housing, starting from the impeller to discharge for the medium to be flowed continuously increases, prevail in the spiral housing continuous pressure differences between different flow cross sections. This fact simplifies the arrangement of the at least one channel and thus the implementation of the method.
• a device for carrying out the method which consists of a housing of a Flusstechnikspumpe having a suction side S with a supply Z for the medium to be flowed and a pressure side D, which is to discharge for the current Medium carries, has, wherein the suction side S and the pressure side D stromungsstechnisch are separated by an impeller of the fluid pump, wherein the housing in the region of a flow cross-section II at least one outlet and optionally at least one inlet for a part of the medium to be flowed, in which the at least one outlet and optionally the at least one inlet are connected to at least one connected channel which is at least partially thermally connected to the components.
• the pressure side D which is separated from the suction side S by a drivable impeller, downstream of this impeller is downstream.
• the direct connection of the channel to the housing has the consequence that only a very small additional space must be provided for the implementation of evaporative cooling.
• the housing in the region of the flow cross-section II only has an outlet which serves both as an outlet and as an inlet for the medium to be flowed. It is advantageous that the channel in the form of a single channel string can be designed constructively, so that let the additional space required to minimize.
• a spiral housing of a centrifugal pump is arranged as a housing.
• Centrifugal pumps are due to their compact design for many applications as liquid pumps.
• the arrangement of the housing as Spiralgehause a centrifugal pump is thus particularly advantageous for many applications.
• the at least one channel is arranged on or in the housing part, which surrounds the electric motor for driving the centrifugal pump. It is advantageous that outside the centrifugal pump no additional space is required to remove the accumulated heat from the components by evaporative cooling.

• Fig. 2 shows the Flusstechnikspumpe in longitudinal section with an outlet.
• a centrifugal pump used as Flusstechnikspumpe is shown in longitudinal section.
• the liquid pump is provided with components 3, which are heated during operation and whose heat must be continuously dissipated during operation.
• the liquid pump 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 (not shown) for the medium to be flowed on, wherein the suction side S and the pressure side D stromungsstechnisch by a drivable impeller 4 are separated from each other.
• a portion of the medium to be flowed is branched off in the region of the flow cross-section II of the pressure side D and passed through at least one channel 2 to the components 3.
• the at least one channel 2 is thermally in communication with these components 3.
• the flow cross-section II is greater than the flow cross-section I formed.
• the pressure to be set in the pressure side D is greater for larger flow cross sections than for smaller flow cross sections.
