Detailed Description
In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the present application.
Fig. 1 shows in a schematic diagram one example of a water collection and utilization system for a fuel cell vehicle of the present application. The fuel cell vehicle may be a hydrogen fuel cell vehicle or a methanol fuel cell vehicle. The fuel cell 1 of such a fuel cell vehicle generates water when operated. If the produced water is discharged directly to the outside environment, it may be wasteful of water on the one hand and may cause road icing on the other hand. For this purpose, a water collection and utilization system is proposed for collecting and utilizing water generated by the fuel cell 1.
As shown in fig. 1, the water collection and utilization system includes:
a collector 2 for collecting water generated by a fuel cell 1 of the fuel cell vehicle;
a cooling device 4, the cooling device 4 being used for performing a cooling action on a member to be cooled of the fuel cell vehicle by means of the collected water;
a controller 8, said controller 8 being adapted to control the cooling behaviour of said cooling means 4 based at least on the water level in said collector 2 and the temperature of said member to be cooled.
The collector 2 prevents water generated by the fuel cell 1 from being directly discharged, thereby avoiding waste of water. By means of the controller 8, an efficient use of the collected water is enabled. The collector 2 is in particular a water tank. "controlling the cooling behavior of the cooling device 4" is understood to include, in particular, both controlling whether a cooling behavior is to be carried out and controlling the magnitude of the cooling power of the carried out cooling behavior.
The component to be cooled is, for example, the fuel cell 1 (see fig. 1), but may be another component.
In order to obtain the water level in the collector 2, the collector 2 comprises, for example, a water level detection means. As for the temperature of the member to be cooled, if the member to be cooled, for example, the fuel cell 1 itself is provided with a temperature sensor, the controller 8 may know the temperature of the member to be cooled directly from the temperature sensor. If the component to be cooled does not have a temperature sensor, it is conceivable, for example, to additionally provide the component to be cooled with a temperature sensor.
According to an exemplary embodiment of the present application, the water collection and utilization system includes the fuel cell 1.
According to an exemplary embodiment of the present application, as shown in fig. 1, the cooling device 4 comprises a cooling line 41, which cooling line 41 passes through the component to be cooled for performing a cooling action. Cooling is achieved in particular in the following manner: the wall of the cooling line 41 is attached to the component to be cooled to remove heat from the component to be cooled. The cooling line 41 is in particular a copper tube. The cooling line 41 forms in particular a cooling circuit.
Alternatively or in addition to the cooling line 41, it is conceivable to: the cooling device 4 comprises a nozzle for spraying water to the component to be cooled to perform the cooling action. Some corrosion resistant components in fuel cell vehicles may be cooled in this way, for example.
According to an exemplary embodiment of the present application, controlling the cooling behavior of the cooling device 4 comprises controlling the water flow of the cooling line 41 and/or controlling the amount of water sprayed by the nozzle. Controlling the water flow of the cooling line 41 includes, in particular, controlling both whether water is fed into the cooling line 41 and the amount of water fed into the cooling line 41. Controlling the amount of water sprayed by the nozzle is similarly understood.
For said control, the cooling device 4 comprises, for example, a cooling pump 94 and/or a valve which can be controlled by the controller 8.
According to an exemplary embodiment of the present application, the water collection and utilization system comprises a cooling activation switch for activating a cooling function, which, if activated by the cooling activation switch, is allowed to perform a cooling action by means of the cooling device 4. Thereby enabling human intervention in the cooling function. If the cooling function is not activated by the cooling activation switch, the cooling action by means of the cooling device 4 is not allowed to take place. At this time, the controller 8 does not process the water level information and the temperature information and does not activate the cooling device 4, for example. The cooling activation switch comprises, for example, a button operable by the driver, physical or on a touch screen.
According to an exemplary embodiment of the present application, the cooling device 4 is shut down in case the water level in the collector 2 is below a water level threshold and/or the temperature of the component to be cooled is below a temperature threshold. The water level threshold is in particular a threshold for discriminating whether the water quantity in the collector 2 is insufficient, which indicates that the water quantity in the collector 2 is sufficient if the measured water level is above the water level threshold, and that the water quantity in the collector 2 is insufficient if the measured water level is below the water level threshold, at which point the cooling pump 94 for the cooling device 4 is likely to idle if the cooling action is continued. The temperature threshold is especially a threshold for discriminating whether the member to be cooled is overheated or not, if the measured temperature is lower than the temperature threshold, the temperature of the member to be cooled is normal without cooling, and if the measured temperature is higher than the temperature threshold, the temperature of the member to be cooled is too high to be cooled.
According to an exemplary embodiment of the present application, the cooling device 4 is only allowed to perform a cooling action in case the water level in the collector 2 is above a water level threshold and the temperature of the component to be cooled is above a temperature threshold. It is conceivable that: in case the cooling function is activated by a cooling activation switch, the water level in the collector 2 is above a water level threshold and the temperature of the component to be cooled is above a temperature threshold, the controller 8 causes the cooling device 4 to perform a cooling action. But it is also conceivable to: there is no cooling activation switch, but the controller 8 automatically causes the cooling device 4 to perform a cooling action as soon as the water level in the collector 2 is above a water level threshold and the temperature of the component to be cooled is above a temperature threshold.
In addition to the above-described control mode of the controller 8, it is also conceivable to: the controller 8 increases the water flow in the cooling line 41 and/or the amount of water sprayed by the nozzles when the water level in the collector 2 is high and/or the temperature of the component to be cooled is high, whereas the controller 8 decreases the water flow in the cooling line 41 and/or the amount of water sprayed by the nozzles when the water level in the collector 2 is low and/or the temperature of the component to be cooled is only slightly above the temperature threshold, or the like. The final objective is to achieve efficient operation of the water collection and utilization system and maximum cooling efficiency.
According to an exemplary embodiment of the present application, the controller 8 is adapted to indicate an insufficient amount of water in case the cooling function is activated by a cooling activation switch and the water level in the collector 2 is below a water level threshold. The prompt is in particular displayed on a dashboard or central control screen and/or given by means of a voice broadcast. It is also conceivable that the collector 2 has a water replenishment mechanism for replenishing the collector 2 with water. The water replenishing means is used, for example, for artificially adding water into the collector 2 or for replenishing water into the collector 2 by collected rainwater.
According to an exemplary embodiment of the present application, as shown in fig. 1, the water collection and utilization system includes a purified water supply device 6, the purified water supply device 6 being configured to purify water obtained from the collector 2 and output the purified water. For purifying the water, the clean water supply device 6 is provided in particular with a filter element 3. The water output is especially potable, whereby the occupants do not have to carry drinking water on board. As shown in fig. 1, the water purification apparatus 6 may include a drinking water outlet 61 and a drinking water recovery port 62 provided below the drinking water outlet 61. The potable water recovery port 62 is used to direct the multiply discharged water to the collector 2. The clean water supply device 6 may in particular also have a heating unit for heating the water. The heating unit heats water using, for example, waste heat generated from the vehicle.
According to an exemplary embodiment of the present application, the water collection and utilization system includes a water outlet switch for activating a water purification providing function. When the water outlet switch is operated, drinking water can flow out from the drinking water outlet 61.
According to an exemplary embodiment of the present application, the controller 8 is adapted to control the clean water providing device 6 based at least on the water level in the collector 2. The clean water supply device 6 is shut down, for example in case the water level in the collector 2 is below a water level threshold; the clean water supply device 6 can be operated by operating the water outlet switch only in case the water level in the collector 2 is higher than the water level threshold. Thereby preventing the pump 96 for the purified water supply device 6 from idling.
According to an exemplary embodiment of the present application, the controller 8 is adapted to indicate an insufficient amount of water in case the clean water providing function is activated and the water level in the collector 2 is below a water level threshold. The presentation means can be referred to herein as the presentation means in the cooling function, for example.
According to an exemplary embodiment of the present application, the water collection and utilization system comprises a humidifying device 5, the humidifying device 5 being adapted to atomize water obtained from the collector 2 and to output the atomized water. As shown in fig. 1, the humidifying device 5 includes, for example, an atomizer 51. The water atomized by the atomizer 51 is discharged, for example, through an air conditioner outlet 52 to wet the environment inside the vehicle. As shown in fig. 1, the humidifying device 5 shares a single filter element 3 with the purified water supply device 6, for example.
According to an exemplary embodiment of the present application, the water collection utilization system includes a humidification switch for activating a humidification function. When the humidifying switch is operated, the humidifying function can be started.
According to an exemplary embodiment of the present application, the controller 8 is adapted to control the humidifying device 5 based at least on the water level in the collector 2. The humidifying device 5 is shut down, for example, in case the water level in the collector 2 is below a water level threshold; the humidifying device 5 can be operated by operating a humidifying switch only in case the water level in the collector 2 is higher than a water level threshold. Thereby preventing the pump 95 for the humidifying device 5 from idling.
According to an exemplary embodiment of the present application, the controller 8 is configured to receive in-vehicle humidity information and control the humidifying device 5 according to the in-vehicle humidity information. It is conceivable that the controller 8 operates the humidifying device 5 only when it is detected that the humidity in the vehicle is low and the water level in the collector 2 is above the water level threshold value, in the case that the humidifying function is activated. If the humidity in the vehicle is normal, the humidifying device 5 does not operate even if the humidifying function is activated by the humidifying switch.
According to an exemplary embodiment of the present application, the controller 8 is adapted to indicate an insufficient amount of water in case the humidifying function is activated and the water level in the collector 2 is below a water level threshold. The presentation in this case can also be referred to as the presentation in the cooling function.
According to an exemplary embodiment of the present application, the water collection and utilization system comprises a drain 11, the drain 11 being adapted to ensure that the water level in the collector 2 is below an upper water level limit by draining. Thereby preventing water from overflowing. In a simple case, the drainage means 11 comprise, for example, a drain pipe connected to the collector 2. The drain pipe is connected to a drain port in the upper portion of the collector 2 so that water is drained from the drain pipe when the water level in the collector 2 exceeds the height of the drain port. Alternatively or additionally, the drain device 11 comprises a drain pump. The drain pump is controlled, for example, by a controller 8. When the water level detection means detects that the water level in the collector 2 is higher than the upper water level limit, the controller 8 controls the drain pump to be turned on.
The water collection and utilization system further comprises a plurality of check valves 7, for example, depending on the requirements. A check valve 7 is here exemplarily marked.
