- This flow can with a suitable geometric arrangement of the conveyor unit a b
- this ty ⁇ pically has a pump to generate the fluid flow.
- the energetic supply of a plurality of modules only requires a central one
- ⁇ module and system is particularly preferably designed for a Be ⁇ operating temperature range between 200 ° C and 400 ° C. Such temperature ranges are preferred especially for Hochtem ⁇ peraturbatteriemodule who work as based on the technology of NaS- or NaNiCl 2 cells. Since such cells sometimes have high heat exchange rates during operation between cells and thermal fluid, the present invention is particularly suitable for such cells or temperature ranges.
- the thermal fluid Wenig ⁇ least partially surrounding the fluid energy machine and with this change in thermal ⁇ effective.
- the fluid energy machine can also be completely embedded in the thermal fluid, so that no further structural measures for a fluidic coupling of the two more must be taken. Due to the thermal integration of the fluid energy machine, this can also be provided for thermal interaction with the thermal fluid, so that about when supplying the fluid energy machine with thermally conditioned fluid in the fluid line and indirectly via the fluid energy machine thermal Kondi ⁇ tioning of the thermal fluid can be done in the module ,

- For fluid sealing of the module housing can be fluid-tightly connected as a part of the housing of the fluid machine ⁇ energy with the module housing, preferably welded.
- a Kupp ⁇ development component may be coupled fluid-tight to the module housing only, so that both sides of the on ⁇ drive unit and the conveying unit can be attached to the coupling component, in particular plugged and secured mechanically Kgs ⁇ NEN.
- Such a coupling component may be formed as a magnetic coupling.
- the fluid energy machine is modular ⁇ built, with individual machine modules can be connected to each other by means of secure connectors. Such machine modules may be about the conveyor unit and the on ⁇ drive unit.
- the module is designed as a memory module having a number of Hochtem ⁇ peraturbatteriezellen (z. B. NaS- or NaNiCl 2 cells). The number here can be "one" or even a number greater than "one".
- the present invention can also be used outside electrochemical applications, namely whenever a module is to be tempered by a thermofluid impinged by a flow. In this respect, it is hereby expressly pointed out that the invention in its most general form does not have to relate to a memory module with a number of high-temperature battery cells.
- the fluid energy machine is to have no further connections for the Ver ⁇ supply to an external power source.

So it is for example conceivable that the Fluidan ⁇ circuit which is arranged in or on the module Fluidenergyma ⁇ machine connects via an opening in the housing module with the same.
- the supply of this fluid connection with fluid can be effected, for example, from a volume in which no directed fluid flow is yet formed, so that the fluid conduit is first formed with a directed fluid flow through the fluid connection.

- a disadvantage of such embodiments is that the individual modules can be acted upon with different pressures and thus, in the case of a parallel connection of the modules, different flows which are practically handled only with considerable additional effort.
- such technical solutions would require a very complex ventilation of the individual modules, about to avoid air bubbles that might otherwise have a negative effect on the Le ⁇ service life of the thermal fluid.
- further measures would have to be taken in order to be able to easily exchange the individual modules from the overall system without jeopardizing the operation of the remaining modules.
- the thermal bridge which is problematic between conveying unit and drive unit, which is problematic according to the prior art, can now be spatially displaced, for example, to a flow generator (pump) centrally connected to the fluid circuit, if, for example, additional insulation is provided around the modules and the fluid energy machines becomes.

On- The reason for such damping is particularly in the
- the fluid in the fluid line does not coincide with the thermal fluid in the module.
- the fluid in the fluid line may have a lower quality valent thermofluid or even a thermally non ⁇ insulating thermofluid be.
- the fluid circuit can be thermally connected to a heating device, in particular outside the module, by means of which the fluid in the fluid line can be thermally conditioned. Consequently, the module can be made not only mechanical energy for driving the drive unit to supply ⁇ addition, but also thermal energy is used to condition the thermal fluid in the thermal module suitable. As already stated above, such a module can be supplied via a fluid circuit simultaneously with mechanical, as well as thermal energy.

- Module housing 2 can be formed.
- suitable discharge from the delivery unit can be caused by the output thermal fluid 3 in the interior of the module 1 as a circle ⁇ flow.
- This serves in particular for improved heat transfer between the high-temperature battery cells 50 and the thermal fluid 3.
- the drive unit 11 of the fluid energy machine 10 is finally supplied from ⁇ by the fluid flow 16 in the fluid line 14 with a driving torque.
- This is provided indirectly via the pump 35, which is connected to the fluid circuit 15 outside the module 1.
- the fluid circuit 15 for additional Be ⁇ woman on top of thermal energy by means of the fluid stream 16, it can also still be supplied with thermal energy via a heating device 13 which is also connected in the fluid circuit 15.
