Definitions
- Function module for a coolant circuit of a fuel cell system and method for manufacturing a functional module and container for a coolant circuit of a
- the invention relates to a functional module for a coolant circuit of a fuel cell system provided in particular for a vehicle.
- the functional module comprises a container which has an ion exchanger material, and a pump device for the coolant.
- a coolant inlet and a coolant outlet of the pumping device are fluidically coupled to a coolant outlet and a coolant inlet of the container.
- the invention relates to a method for manufacturing such a functional module for a coolant circuit of a fuel cell system and a container for a coolant circuit.
- the coolant of a fuel cell system should be as pure as possible, in particular with regard to the conductivity, ie with regard to ions dissolved in the coolant. This is v. A. necessary because a fuel cell system for mobile applications, such as for a vehicle, is designed to generate a high voltage, so that a low conductivity of the coolant of a coolant circuit of the fuel cell system must be ensured with respect to the insulation resistance of the coolant relative to the vehicle body.
- Fuel cell system integrated a container with an ion exchange material. Furthermore, in the cooling circuit, a filter material may be integrated, which traps particles, so dirt, detachments and residues and thus in particular keeps away from the narrow coolant channels, which dissipate the heat from the fuel cell stack to prevent their clogging.
- DE 10 2009 023 863 A1 describes an integrated coolant pump module in which a pump housing is formed integrally with a housing of a deionization filter. A coolant inlet of the filter receives coolant from the high pressure side of the pump during operation of the coolant pump. The coolant then flows through a filter element, and a coolant outlet of the deionization filter is fluidically coupled to a low pressure side of the coolant pump.
- Object of the present invention is to provide a functional module of the type mentioned above and a method for manufacturing such a functional module, which has an extended functionality.
- the container which has the ion exchanger material surrounds at least one delivery unit of the
- Pumping device having region of the pumping device at least partially outer peripheral side. This is based on the finding that the delivery unit of the pumping device releases heat in pumping operation. Now, if the container with the ion exchanger material surrounds the delivery unit on the outer peripheral side, a cooling of the pumping device can be ensured particularly well by dissipating heat via the coolant which flows through the ion exchanger material. Likewise, in cold weather, the delivery unit of the pumping device can contribute to the transfer of heat to the coolant for heating purposes.
- the function module thus has an extended functionality.
- the shape of the container which is matched to the shape of at least the delivery unit of the pumping device, that only designed for the coolant circuit and matched to this container with the

- Coolant inlet and coolant outlet of the pumping device and the container to each other thus ensures that a lot of pressure for flowing through the ion exchanger material is available.
- the container may be provided in particular a positive and / or non-positive connection of the container with the pumping device. Then the container is particularly easy to install quickly and without further brackets and even when driving typical vibration (shaking), the container is securely held on the pumping device.
- a spring, a thread, a lever, a clamp or the like can be used, and the container can be guided in grooves, rails or the like guided on the pumping device.
- the container can be guided, plugged and / or screwed and / or latched to the pumping device. Achieving a desired
- Installation position here can be noticeable, audible and / or communicable via an end stop of the operator for an operator. It can also be a defined revolution of the container about a quarter or a half full
- the container and at least the conveying unit of the pumping device are arranged axially parallel, wherein the conveying unit is arranged at least over a part of its longitudinal extension direction in a receiving space formed by the container.
- the container comprises a coil having the ion exchanger material, which at least around the conveyor unit of the
- Pumping device is formed on the outer peripheral side circumferentially. This allows a particularly long distance of the coolant flow to the conveyor unit of
- Heat transfer from the conveyor unit is beneficial to the coolant.
- the container is at least partially with at least one of the pumping means different and heat-releasing in operation component of the fuel cell system in Appendix. Then, not only by the pumping device, but also by this further component, heat can be dissipated well via the container through which the coolant flows.
- the component may be, for example, a compressor, a turbocharger, an anode module, a cathode module and / or power electronics of the fuel cell system.
- the container is in
- the functional module can comprise a cover element, by means of which the container can be shielded towards an environment, wherein between the cover element and the container, a spring element is arranged, by means of which the coolant inlet and / or the coolant outlet of the container with the coolant inlet and / or
- Coolant outlet of the pumping device can be brought into contact.
- the container ensures a tight-fitting fluidic coupling of the container with the pumping means, and on the other hand, the container is particularly well protected from environmental influences.
- the coolant inlet and / or the coolant outlet of the container has a separating layer, which by means of a fluid coupling with the coolant outlet and / or the coolant inlet of the pumping device by means of a Actuator is destructible. So before the coupling of the container with the pumping device through the separating layer contamination of the
- the avoidance of an ingress of atmospheric moisture to the ion exchanger material prevents its aging and thus allows a particularly long storage period before the use of the container in the coolant circuit. The same applies to a discharge of moisture from the
- the separating layer or membrane can also enclose the complete container in the manner of a protective cover and thus shield the ion exchanger material, in particular an ion exchange resin, against external influences such as moisture and contamination. However, it may also be provided to prevent unwanted aging of the ion exchange material, a vacuum in the container. Instead of the separating layer, it is also possible to provide plugs and / or removable or tearable films or the like. Alternatively, the destruction of the release layer may alternatively be done by an operator, such as peeling or tearing, if none
- Actuating element is provided, which ensures the installation of the container in the functional module for destroying the separation layer.
- the separating layer releases in a particularly simple and targeted manner at least one passage for coolant, in particular a perforation and / or a weakening of the separating layer can be provided.
- a perforation can for example be formed star-shaped, or it can be swung open a portion of the release layer in the manner of a flap when marginal boundaries of the flap are designed as weakenings of the release layer.
- the approximately designed as a cone or mandrel or the like actuating element, in particular on the side of the pumping device may be arranged so that when fluidically coupling the container with the
- a pressurizing element is preferably provided, which exerts a pressure on the ion exchanger material located in the receptacle.
- the pressurizing element may be designed in the manner of a spring, which prevents a void volume from forming in the volume occupied by the ion exchanger material. As a result, a homogeneous flow through the ion exchanger material can be achieved and the formation of preferred
- Flow channels are prevented by the ion exchange material. This improves the effect of the ion exchange material in the coolant circuit.
- the spring may press on a movable piston disposed within the container.
- a movable piston disposed within the container.
- it may also be a filter material, such as glass fiber fleece, membrane, plastic fabric, metal mesh or frit, e.g. out
- Borosilicate glass may be formed for the compression of the
- ion exchange material such as by the filter material swells. Through the filter material, the ion exchange material is retained under pressure in the container. Contamination of components of the coolant circuit is also prevented by the filter material.
- the container has at least one actuating element by means of which a closing element designed to close the coolant inlet and / or the coolant outlet of the pumping device can be actuated. Namely, if the coolant inlet and / or the coolant outlet has the closing element, the coolant inlet and / or the coolant outlet are closed, as long as the container is not connected to the pumping device.
- the closing element closes the associated inlet or outlet. Then no impurities can enter the coolant.
- the closure is effected simply by dismantling the container, and when coupling the container to the pumping means, the actuator ensures that the closure member is moved to an open position.
- the closing element also ensures that no loose ion exchange material can be introduced into the coolant circuit as bulk material or ion exchange material packed in bags or the like. Only the installation of the container causes namely the opening of the closing element by the
- Actuator moves the closing element.
- a closing element a bolt or a slider, a check valve, a movable flap, a turntable or the like can be used.
- a mandrel or pin, a cone, for moving the closure element, an eccentric, a wedge, a ball or hemisphere or a cam may be provided as an actuating element.
- a switch can be actuated during the assembly of the container, the actuation of the switch then providing the closure by means of an actuator for closing.
- an electromechanical switch such as a micro contact switch or magnetic switch can open or close an electrical contact. The opening or closing of the contact can in this case bring about the release or blocking of the coolant inlet and / or the coolant outlet.
- Such an electrical contact may be formed, for example, as a finger contact.
- the opening and closing of the electrical contact may additionally or alternatively ensure that the electrical energy flow is influenced or interrupted to a functional unit of the coolant circuit. This can be done directly or via a control unit.
- a functional unit of the coolant circuit which is activated in this case, can influence the coolant flow, such as an electric pump or an electrical control valve. This can ensure that no further promotion of coolant takes place as soon as the container is disconnected from the pumping device.
- a non-contact controllable switch may be provided, such as a magnetically passive switch, and / or the non-contact switch may comprise a chip, as in a radio frequency identification (RFID) system.
- RFID radio frequency identification
- Radio frequency identification is used.
- Such non-contact switches or RFID chips can ensure that the coolant inlet and / or the
- Coolant outlet is released or closed, depending on whether the container is coupled to the pumping device or removed.
- Instrument cluster of the vehicle activates a warning message and / or prevents starting of the fuel cell system, if a manipulation or installation of a not identifiable container is detected in the functional module.
- the signal may also generate error codes for diagnostic purposes, such as troubleshooting or short tests.
- the time of the coupling of the container with the pumping device and / or the operating time of the container can also be determined via the signal that can be generated by a mechanical switch or a touchless switch and a corresponding data value can be stored in a control unit.
- the state of the ion exchange material in particular its effectiveness,
- the proper installation of the container in the functional module can be determined by the presence of coolant in the container. For as long as the container is not in contact with the coolant and thus dry, the ion exchange material and optionally a filter material are unused.
- Ion exchange material and optionally the filter material so if they come into contact with the coolant, there is a change in the state of these materials.
- the presence of coolant in the container can in this case be determined by means of a measuring device, for example by an inductive measuring process, in which a coil arranged on or in the region of the pump device is a different one in each case
- Another way of assessing the state of the ion exchange material and thus the duration of use of the same is to perform a wall of the container partially or completely transparent, so that the coolant and the ion exchange material are visible from the outside. Thus, a functional check and diagnosis can be made optically.
- the ion exchange material may fill the container completely or partially. It may be attached to the inside of a wall of the container, such as in pockets, or it may be inextricably, for example, chemically bonded, in the wall material of the
- the ion exchange material may be embedded. Furthermore, it may e.g. be glued to the wall of the container. If the ion exchange material is not firmly connected to the container, a simple replacement of the ion exchange material is made possible.
- this can for example be housed in a separate container, such as a cartridge or cartridge.
- This container can in turn be accommodated in the container provided for the ion exchanger material and optionally a filter material. Then it is possible the container, which is both the
- ion exchange material as well as optionally containing the filter material, expand and in a clean workplace, especially under clean room conditions, the separate cartridge or cartridge or the like with the used, saturated ion exchange material to renew. But also possible is the direct replacement of the separate cartridge or cartridge with still built into the functional module container.
- self-sealing interfaces for example in the form of diaphragms and / or check valves, are provided on the container and / or on the pump device, in order to prevent a coolant outlet during installation or removal of the container.
- a simple, quick and clean installation of the new container can be ensured, as is for service work, such as in the context of maintenance and / or repair advantage. This is beneficial if the container is packed dirt-free, transported and delivered, and if the coolant circuit is only briefly opened to install the container.
- the length of connecting tubes can be reduced. This has a positive effect on the packaging and component weight. Such a reduced weight and compact packaging is particularly favorable if the coolant circuit is to be used in a fuel cell system for a vehicle.
- the container In the installation position, the container may be aligned perpendicular or inclined with respect to the horizontal, or it may be provided to the horizontal substantially parallel orientation of the container. Also favorable is a flow of the ion exchange material with the coolant from bottom to top, ie against gravity. So a particularly homogeneous flow can be guaranteed.
- plastics, rubber, stainless steel, fiber-reinforced materials can be used for the components of the functional module that are in contact with the coolant
- Plastics in particular glass fiber reinforced plastics or the like are used, which are compatible with the usually deionized coolant. This also applies to closing elements and actuators for moving
