Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-9 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

Referring to fig. 1, an embodiment of the present invention provides a cooling control method for a fuel cell, and a main flow of the cooling control method for the fuel cell is described as follows:

step 100: and acquiring current battery number information corresponding to a cooling branch pipe entering the fuel cell stack from the cooling main pipe and adjacent battery number information adjacent and behind the current battery number information.

The current battery number information is the number information of an arbitrarily selected battery, and the selection is to determine the state of the corresponding battery so as to distinguish each battery. The adjacent battery number information is the number of the battery which is behind the current battery number information in the water supply direction of the cooling main pipe, and the cooling water firstly enters the battery corresponding to the current battery number information and then enters the battery with the adjacent battery number information.

Step 101: and performing matching analysis according to the water outlet pipeline number information and the current battery number information stored in the preset pipeline database to determine the water outlet pipeline number corresponding to the current battery number information, defining the water outlet pipeline number information as the current water outlet pipeline number information, wherein two water outlets corresponding to the current water outlet pipeline number information are provided, one of the two water outlets is defined as straight water outlet number information, and the water outlet flowing into the adjacent battery number information is defined as the adjacent connecting port number information.

The current water outlet pipeline number information is the number information of the cooled water outflow pipeline of the cooling branch pipe on the battery corresponding to the current battery number information, mapping relations of all pipelines including the water outlet pipeline number information and the current battery number information are stored in the database, and corresponding relations are edited and stored in the database after being numbered by workers in the field according to actual conditions. As shown in FIG. 2, the water outlet of the water outlet pipeline has two water outlets, one is led to a lower recovery main pipe for recovering cooling water, and the other is led to the battery with the number information of the adjacent battery. When the system receives the current battery number information, all corresponding pipelines are automatically searched from the database, and then the water outlet pipeline number information is selected from the corresponding pipelines for output.

Step 102: and performing matching analysis according to the water inlet pipeline number information and the adjacent battery number information stored in the pipeline database to determine the water inlet pipeline number corresponding to the adjacent battery number information, and defining the water inlet pipeline number as the adjacent water inlet pipeline number information.

The adjacent water inlet pipeline number information is information of the number of the water inlet pipeline on the cooling branch pipe corresponding to the battery directly entering the adjacent battery number information from the cooling main pipe. When the system receives the serial number information of the adjacent batteries, the serial numbers of the adjacent batteries are automatically analyzed, all corresponding pipelines are searched from the database, and then the corresponding water inlet pipelines are selected from the serial number information of the adjacent water inlet pipelines to be output.

Step 103: and acquiring current outlet water temperature information in the current outlet water pipeline number information.

And the current outlet water temperature information is the temperature of the cooling water flowing out from the outlet pipeline number information. The temperature is obtained by a temperature detection device arranged on the water outlet pipeline, such as a temperature sensor.

Step 104: and judging whether the current outlet water temperature information is larger than the preset temperature threshold value information.

The temperature threshold information is a critical value of the temperature, that is, the cooling effect of the corresponding cooling water on the next battery is not good when the temperature threshold information exceeds the critical value. The value set by the staff in the field according to the actual situation can also be a variable value, that is, in the case of different environments and battery models, the staff sets according to the past working conditions, and then the system changes in real time according to the setting habit. The purpose of the judgment is to determine whether the water flowing out of the current water outlet pipeline information has a cooling effect.

Step 1041: if the number of the adjacent connecting ports is larger than the number of the adjacent connecting ports, the number information of the straight water outlets is opened, so that cooling water flows out of the recovery main pipe, and the number information of the adjacent water inlet pipelines is opened.

If the number of the connecting ports is larger than the number of the straight water outlets, the cooling effect of the cooling water at the moment is poor, and the cooling effect on the next battery cannot meet the requirements of temperature reduction and even constant temperature, so that the corresponding cooling water needs to be discharged, and therefore, as shown in fig. 2, the number information of the adjacent connecting ports is closed, and the number information of the straight water outlets is opened, so that the cooling water flows out of the recovery main pipe. And the adjacent batteries need to directly flow into the cooling main pipe for cooling, so that the serial number information of the adjacent water inlet pipelines is opened. The way of opening and the tube wall can here be controlled by a solenoid valve.

Step 1042: if the current outlet water temperature information is less than the temperature threshold value, the serial number information of the straight water outlet and the serial number information of the adjacent water inlet pipeline are closed, the serial number information of the adjacent connecting port is opened, and the serial number information of the adjacent battery is updated to be the serial number information of the current battery, and then whether the current outlet water temperature information is greater than the temperature threshold value or not is continuously judged.

If the number of the straight water outlet is less than the number of the adjacent water inlet pipeline, the cooling water can further cool the subsequent battery, so that the number information of the straight water outlet and the number information of the adjacent water inlet pipeline are closed, and the number information of the adjacent connecting port is opened, so that the cooling water flows into the cooling branch pipe in the adjacent battery, as shown in fig. 2.

Referring to fig. 3, the method for closing the number information of the current straight water outlet and the number information of the adjacent water inlet pipeline and opening the number information of the current adjacent connecting port comprises the following steps:

step 200: the number of the battery which is fed with water through the number information of the adjacent water inlet pipe is defined as the initial battery number information, the number of the battery which is fed with water through the number information of the adjacent connector is defined as the middle battery number information, and the number information of the adjacent middle battery which is positioned before the next initial battery number information is defined as the terminal battery number information.

The initial battery number information is the battery number of the water inlet through the adjacent water inlet pipeline number information, namely the number of the battery which directly flows water from the cooling main pipe to the cooling branch pipe of the battery. The middle battery number information is the battery number of the inlet water through the adjacent connector number information, namely the cooling water on the middle battery number information flows out from the cooling branch pipe on the previous battery number information. The end battery number information is intermediate battery number information that is closest to and located one before the start battery number information in the flow direction of the cooling main pipe.

Step 201: and acquiring initial inlet water temperature information and initial outlet water temperature information corresponding to the initial battery number information.

The initial inlet water temperature information is information of the water temperature before entering the cooling branch pipe on the initial battery number information, and is substantially the water temperature of the cooling main pipe. The initial outlet water temperature information is the information of the temperature of the water flowing out of the cooling branch pipe on the initial battery number information. The acquisition mode is a temperature sensor.

Step 202: and judging whether the initial outlet water temperature information is changed.

The purpose of the judgment is to determine whether or not a state of equilibrium has been reached with the heat dissipation of the initial battery number information. The amount of heat exchanged between the cooling water and the battery at this time via the initial battery number information is just in equilibrium with the amount of heat generated by the battery due to combustion. The flow rate of the cooling water set here was obtained through experiments, i.e., the flow rate measured when the battery was maintained at the optimum operating temperature, the cooling water flowed in from one end to the other, and the battery was maintained at the normal operating temperature.

Step 2021: if so, continuing to acquire.

If the temperature changes, the balance is not achieved at the moment, and the initial effluent temperature information needs to be obtained continuously.

Step 2022: if not, performing matching analysis according to the heat exchange efficiency information, the initial inlet water temperature information and the initial outlet water temperature information stored in the preset heat exchange database to determine the heat exchange efficiency corresponding to the initial inlet water temperature information and the initial outlet water temperature information, and defining the heat exchange efficiency as the heat generation efficiency information of the battery.

The battery heat generation efficiency information is information on the rate of heat generated by the battery through combustion, and when equilibrium is reached, is information on the rate of heat exchanged with the cooling water. The mapping relation of the heat generation efficiency information of the battery, the initial inlet water temperature information and the initial outlet water temperature information is stored in the database and is obtained by workers in the field through test results and actual conditions, namely after the heat generation efficiency of the battery is obtained through calculation by a user, the corresponding battery passes through different initial inlet water temperature information, and after the outlet water temperature is stable, the corresponding initial outlet water temperature information is obtained, and then the relation of the three is input and stored. And when the system receives the initial inlet water temperature information and the initial outlet water temperature information, automatically searching the corresponding battery heat production efficiency information from the database and outputting the corresponding battery heat production efficiency information. The purpose of this acquisition is to determine the heat generation efficiency of the battery itself.

Step 203: and acquiring terminal inlet water temperature information corresponding to the terminal battery number information.

The terminal inlet water temperature information is information of the temperature of water on the battery from which the terminal battery number information is entered from the intermediate battery number information. The acquisition mode is temperature sensor acquisition.

Step 204: and performing matching analysis according to the inlet water temperature information, the battery heat generation efficiency information and the temperature threshold information stored in the heat exchange database to determine the inlet water temperature corresponding to the battery heat generation efficiency information and the temperature threshold information, and defining the inlet water temperature as theoretical inlet water temperature information.

The theoretical inlet water temperature information is the theoretical inlet water temperature information when the heat of the battery heat generation efficiency information is exchanged with the battery and the outlet water temperature is the temperature threshold information. The database stores the mapping relationship of the three, and when two of the three are known, the third information can be obtained. And when the system receives the heat generation efficiency information and the temperature threshold information of the battery, automatically searching the corresponding theoretical inlet water temperature information from the database.

Step 205: and calculating according to the theoretical water inlet temperature information, the terminal water inlet temperature information and the preset water flow speed information to obtain the main pipe water inlet speed information.

The main pipe water inlet speed information is the information of the water inlet speed at the position of the water inlet pipeline number information corresponding to the terminal battery number information. The water flow velocity information is information of the flow velocity flowing from the intermediate battery number information preceding the end battery number information to the cooling branch pipe of the battery of the end battery information through the adjacent connector number information. The calculation mode is that the product of the tail end inflow water temperature information and the water flow speed information and the product of the main pipe inflow water speed information and the initial inflow water temperature information are equal to the product of the theoretical inflow water temperature information and the sum of the water flow speed information and the main pipe inflow water speed information, and then the solution of the equation is solved, wherein the solution is the main pipe inflow water speed information.

Step 206: and (4) feeding water into the water inlet pipeline corresponding to the terminal battery number information according to the main water inlet speed information.

When the water inlet speed information of the main pipe is known, the water flowing into the cooling main pipe is carried out according to the water inlet speed, so that the water temperature of the cooling branch pipe entering the terminal battery number information reaches the theoretical water inlet temperature information, and then the water temperature flowing out is kept close to the temperature threshold value as far as possible, so that the situation that the effect is poor due to the fact that the temperature of the last part in the flowing process is higher than the temperature threshold value is guaranteed not to be higher than the temperature threshold value.

Referring to fig. 4, the method for feeding water into the water inlet pipeline according to the water inlet speed information of the main pipe and corresponding to the terminal battery number information includes:

step 300: and performing matching analysis according to the corresponding water storage cavity number information and the tail end battery number information in the preset water storage database to determine the water storage cavity number corresponding to the tail end battery number information, and defining the water storage cavity number as the water storage cavity number information.

The water storage chamber number information is a chamber capable of storing water and arranged for controlling the flow rate of water entering the cooling branch pipe corresponding to the terminal battery number information, and as shown in fig. 2, the water military on the water inlet pipeline number information and the adjacent connector number information is output through the water storage chamber number information. All the battery number information including mapping relations between the terminal battery number information and the water storage cavity number information is stored in the database, and the mapping relations are obtained by numbering according to actual conditions and inputting the corresponding mapping relations by workers in the field. And when the system receives the corresponding terminal battery serial number information, the corresponding water storage cavity serial number information is automatically searched from the database and is output. The reason why the water storage chamber is provided here is that a state of equilibrium cannot be achieved because the water inlet rate and the water outlet rate are different.

Step 301: and acquiring water level height information corresponding to the water storage cavity number information.

The water level height information is information of the height of the water level in the water storage chamber and is obtained by the water level detector.

Step 302: and judging whether the water level height information is less than the preset full cavity height information.

The full cavity height information is information of the height of the water storage cavity filled with water. The purpose of the judgment is to determine whether the chamber will be full and water cannot enter.

Step 3021: and if the number information is equal to the full cavity height information, closing the water inlet pipeline number information corresponding to the terminal battery number information and the adjacent connector number information of the previous middle battery number information.

If the water level is equal to the preset water level, the water level is over high and water cannot enter, the water inlet pipeline number information corresponding to the terminal battery number information and the adjacent connector number information of the previous middle battery number information are closed, so that only water can be discharged but not enter the water storage cavity, and the water can flow out quickly.

Step 3022: and if the water level height information is less than the full cavity height information, judging whether the water level height information is equal to the waterless height information or not.

The water-free height information is height information of a water level when there is no water in the water storage chamber, and is defaulted to 0 here. The purpose of the judgment is to determine the water inlet state so as to trigger the water inlet condition. The purpose of setting the trigger state is to prevent the situation that once the full-cavity state is achieved, the full-cavity state is achieved instantly once the full-cavity state is separated from the full-cavity state and the electromagnetic valve corresponding to the adjacent connector number information of the previous middle battery number information and the water inlet pipeline number information corresponding to the tail end battery number information is opened and closed frequently.

Step 3031: and if the number information is equal to the waterless height information, opening the number information of the adjacent connector of the number information of the previous middle battery and enabling the number information of the water inlet pipeline corresponding to the number information of the tail end battery to feed water according to the water inlet speed information of the main pipe.

If the number of the adjacent connectors is equal to the number of the adjacent connectors, the number information of the adjacent connectors is triggered to be opened, and the number information of the water inlet pipeline corresponding to the number information of the terminal battery enters water according to the water inlet speed information of the main pipe, so that water begins to enter.

Step 3032: and if the current state is larger than the waterless height information, maintaining the current state.

If the current state is larger than the full cavity height state, maintaining the current state, wherein when the current state falls from the full cavity height state, the state of closing the water inlet pipeline number information corresponding to the terminal battery number information and the adjacent connector number information of the previous middle battery number information is maintained; and when the height of the water tank rises from the waterless height state, the serial number information of the adjacent connector of the serial number information of the previous middle battery is opened, and the serial number information of the water inlet pipeline corresponding to the serial number information of the tail end battery is used for feeding water according to the main water inlet speed information.

Referring to fig. 5, the method for discharging water according to the water flow rate information from the adjacent connection port number information of the previous intermediate battery number information includes:

step 400: and acquiring current outlet water temperature information corresponding to the intermediate battery number information, and defining the current outlet water temperature information as intermediate outlet water temperature information.

The intermediate outlet water temperature information is the outlet water temperature information of the intermediate battery number information. The acquisition mode is temperature sensor acquisition.

Step 401: acquiring the surface temperature information of the fuel cell.

The fuel cell surface temperature information is information on the temperature of the operating surface of the corresponding fuel cell. The acquisition mode is temperature sensor acquisition. Here, the fuel cell housing surface temperature information and the intermediate cell number information correspond one-to-one.

Step 402: and performing matching analysis according to the flow speed information and the intermediate effluent temperature information, the fuel cell shell surface temperature information and the cell heat generation efficiency information stored in the preset flow database to determine the flow speed corresponding to the intermediate effluent temperature information, the fuel cell shell surface temperature information and the cell heat generation efficiency information, defining the flow speed as intermediate flow speed information, defining the intermediate flow speed information corresponding to the previous intermediate cell number information as first intermediate flow speed information, and defining the intermediate flow speed information corresponding to the next intermediate cell number information as second intermediate flow speed information.

The intermediate flow rate information is the temperature of the cooling water in the intermediate outlet water temperature information, the fuel cell performs heat exchange under the condition of the temperature of the surface temperature information of the fuel cell, and the exchanged heat is the flow rate information required when the cell generates heat efficiency information. The first intermediate flow rate information is information of the flow rate in the cooling branch pipe in the previous intermediate battery number information. The second intermediate flow rate information is information of the flow rate in the cooling branch pipe in the next intermediate battery number information. The purpose of distinguishing the first and second is here to determine the order of the front and rear.

The database stores the mapping relation of flow velocity information, intermediate outlet water temperature information, surface temperature information of the fuel cell and heat generation efficiency information of the cell. All parameters are set by workers in the field, then tests are carried out according to different flow rates, and finally the flow rates when the intermediate effluent temperature information and the surface temperature information of the fuel cell shell do not change are recorded.

Step 403: and judging whether the water level height information corresponding to the second intermediate flow velocity information is smaller than the full cavity height information.

Because velocity of flow information is inequality in the middle of first intermediate flow information and the second, and because the great heat conduction of temperature difference is very fast, so the time that the great exchange heat of temperature difference needs is short, so velocity of flow information is greater than velocity of flow information in the middle of the second in the middle of the first, so if the solenoid valve of the adjacent connector number information of the previous in the water storage cavity of the battery number information that velocity of flow information corresponds in the second opens with the solenoid valve that flows into the cooling branch pipe of battery number information all opens, the water level in the water storage cavity is the process that rises, so reach full chamber height information easily. The purpose of judgment is to prevent the situation that the full cavity can not be filled with water due to the fact that the water level is too high.

Step 4031: and if the flow rate is equal to the full cavity height information, closing the adjacent connection port number information corresponding to the middle battery number information corresponding to the first middle flow rate information.

And if the flow rate is equal to the full cavity, indicating that water can not be continuously fed, closing the adjacent connection port number information corresponding to the middle battery number information corresponding to the first middle flow rate information.

Step 4032: and if the water level height information is less than the full cavity height information, judging whether the water level height information corresponding to the second intermediate flow velocity information is equal to the anhydrous height information.

If the water content is less than the predetermined value, it is determined whether water is absent, and the determination is performed in step 3022, which is not described herein again.

Step 4041: and if the flow rate is equal to the waterless height information, opening the adjacent connection port number information corresponding to the middle battery number information corresponding to the first middle flow rate information and the second middle flow rate information according to the flow rates corresponding to the first middle flow rate information and the second middle flow rate information respectively.

If equal, indicating a condition to trigger opening at that time, water intake may begin.

Step 4042: if the current state is larger than the waterless height information, the current state is maintained.

If the flow rate is larger than the first intermediate flow rate, maintaining the current state, wherein when the flow rate falls from the full cavity height state, maintaining the state of closing the adjacent connection port number information corresponding to the intermediate battery number information corresponding to the first intermediate flow rate information; and when the water level rises from the waterless height state, opening the adjacent connection port number information corresponding to the intermediate battery number information corresponding to the first intermediate flow rate information and the second intermediate flow rate information according to the flow rates corresponding to the first intermediate flow rate information and the second intermediate flow rate information, respectively.

Referring to fig. 6, the method of opening adjacent connection port number information corresponding to intermediate battery number information corresponding to first intermediate flow rate information and second intermediate flow rate information at flow rates corresponding to the first intermediate flow rate information and the second intermediate flow rate information, respectively, includes:

step 500: and acquiring water level state information corresponding to the second intermediate flow velocity information, wherein the information from the full cavity height to the waterless height is defined as descending state information, and the information from the waterless height to the full cavity height is defined as ascending state information.

The water level state information is information of dynamic change of the water level. The lowering state information is information of a state of lowering from the full cavity height information to the water-free height information. The rise state information is information of a state from the water-free height information to the full chamber height information.

Step 501: and if the flow rate is in the reduced state information, opening the reflux number information corresponding to the intermediate battery number information corresponding to the first intermediate flow rate information.

The backflow number information is information of a pipe number which can cool the battery corresponding to the next battery number information, and the corresponding water still returns to the corresponding water storage chamber. The correspondence is manually set in advance. If the flow rate information is in the reduced state information, it indicates that the electromagnetic valve of the adjacent connection port number information, which leads the intermediate battery number information corresponding to the first intermediate flow rate information to the intermediate battery number information corresponding to the second intermediate flow rate information, has been closed, and at this time, in order to still cool the battery corresponding to the intermediate battery number information corresponding to the second intermediate flow rate information, it is necessary to flow the corresponding water into the pipeline corresponding to the return flow number information.

Step 502: and calculating main pipe water inlet speed information of the water inlet pipeline number information corresponding to the first intermediate flow speed information according to the second intermediate flow speed information, the intermediate outlet water temperature information corresponding to the intermediate battery number information corresponding to the second intermediate flow speed information and the second intermediate flow speed information, and defining the main pipe water inlet speed information as main pipe recovery speed information.

The main pipe return speed information is the temperature of the water that is cooled and neutralized from the inside of the main pipe, which is required to return the temperature from the return number information to the temperature before entering the water storage chamber. The calculation mode is that the sum of the product of the main pipe water inlet speed information and the initial water inlet temperature information and the product of the middle flow speed information and the middle water outlet temperature information of the previous battery number information is equal to the product of the first middle water outlet temperature information and the sum of the main pipe water inlet speed information and the first middle flow speed information, and then the solution obtained by the equation is the corresponding main pipe recovery speed information.

Step 503: and feeding water according to the main pipe recovery speed information by using the water inlet pipeline number information corresponding to the first intermediate flow speed information.

And the water inlet pipeline number information corresponding to the first intermediate flow rate information is fed according to the main pipe recovery speed information, so that the temperature of the water raised from the return pipeline corresponding to the return pipeline number information is reduced, and the water storage cavity corresponding to the first intermediate flow rate information still has the water inlet temperature corresponding to the first intermediate flow rate information.

Step 504: and if the current flow rate information is in the rising state information, opening the adjacent water inlet pipeline number information corresponding to the middle battery number information corresponding to the first middle flow rate information.

When the water storage chamber is in the rising state, it indicates that the water in the water storage chamber of the intermediate battery number information corresponding to the second intermediate flow rate information is not full, and the corresponding water can flow into the water storage chamber through the corresponding adjacent water inlet pipeline number information.

Referring to fig. 7, a further method of opening adjacent connection port number information corresponding to intermediate battery number information corresponding to second intermediate flow rate information at a flow rate corresponding to the second intermediate flow rate information includes:

step 600: acquiring intermediate outlet water temperature information corresponding to intermediate battery number information corresponding to the first intermediate flow rate information and the second intermediate flow rate information respectively, defining the intermediate outlet water temperature information corresponding to the first intermediate flow rate information as actual inlet water temperature information, and defining the intermediate outlet water temperature information corresponding to the second intermediate flow rate information as actual outlet water temperature information.

The actual inlet water temperature information is intermediate outlet water temperature information corresponding to the intermediate battery number information corresponding to the first intermediate flow rate information. The actual outlet water temperature information is intermediate outlet water temperature information corresponding to the intermediate battery number information corresponding to the second intermediate flow rate information. The acquisition mode is obtained by directly installing corresponding temperature sensors at corresponding positions.

Step 601: and performing matching analysis according to the intermediate outlet water temperature information, the actual inlet water temperature information, the second intermediate flow rate information, the surface temperature information of the fuel cell and the heat generation efficiency information of the cell stored in the flow database to determine the intermediate outlet water temperature corresponding to the actual inlet water temperature information, the second intermediate flow rate information, the surface temperature information of the fuel cell and the heat generation efficiency information of the cell, and defining the intermediate outlet water temperature as the balance intermediate outlet water temperature information.

The balanced intermediate outlet water temperature information is the outlet water temperature information after cooling, when the inlet water temperature is the actual inlet water temperature information and the surface temperature of the fuel cell shell is the surface temperature information of the fuel cell shell, and the heat generation efficiency information of the fuel cell only exchanges heat of the heat generation efficiency information of the fuel cell. When the system receives the actual inlet water temperature information, the second intermediate flow rate information, the surface temperature information of the fuel cell and the heat production efficiency information of the cell, the intermediate outlet water temperature information is automatically searched from the actual inlet water temperature information, the second intermediate flow rate information, the surface temperature information of the fuel cell and the heat production efficiency information of the cell, so that the output of the intermediate outlet water temperature information is balanced.

Step 602: and performing matching analysis according to the intermediate outlet water temperature information, the actual inlet water temperature information, the second intermediate flow rate information and the surface temperature information of the fuel cell, which are stored in the flow database, so as to determine intermediate outlet water temperatures corresponding to the actual inlet water temperature information, the second intermediate flow rate information and the surface temperature information of the fuel cell, and defining the intermediate outlet water temperature as intermediate outlet water temperature information.

The neutralization intermediate outgoing water temperature information is the temperature of the outgoing water flowing out according to the second intermediate flow rate information when the surface temperature of the fuel cell is the surface temperature information of the fuel cell but the cell heat generation efficiency information is not generated during combustion. The database naturally also includes the temperature information of the outlet water when the battery heat generation efficiency information is 0. And when the system receives the actual water inlet temperature information, the second intermediate flow rate information and the surface temperature information of the fuel cell, automatically searching intermediate water outlet temperature information from the actual water inlet temperature information, and outputting the intermediate water outlet temperature information.

Step 603: and judging whether the actual outlet water temperature information is equal to the balance intermediate outlet water temperature information or the neutralization intermediate outlet water temperature information.

The purpose of the judgment is to determine the operating state of the battery to see whether it is operating to generate heat.

Step 6031: and if the flow rate is equal to the middle outlet water temperature information, updating the second middle flow rate information into preset maximum flow rate information.

The maximum flow velocity information is information of the maximum flow velocity when water flows through the pipe. The speed of movement of the water at this pressure is measured manually on the basis of the actual situation, i.e. by adding the maximum pressure at the very beginning. If the temperature is equal to the middle outlet water temperature information, the battery does not work at the moment, and the maximum flow rate information is needed to move so as to reduce the loss on the corresponding cooling branch pipe.

Step 6032: and if the balance intermediate outlet water temperature information is equal to the balance intermediate outlet water temperature information, opening the adjacent connector number information corresponding to the intermediate battery number information corresponding to the second intermediate flow rate information according to the flow rate corresponding to the second intermediate flow rate information.

If the balance intermediate outlet water temperature information is equal to the balance intermediate outlet water temperature information, the battery is indicated to be in combustion work at the moment, and the adjacent connector number information corresponding to the intermediate battery number information corresponding to the second intermediate flow rate information is opened according to the flow rate corresponding to the second intermediate flow rate information so as to cool the battery corresponding to the second intermediate flow rate information.

In the embodiment of the present application, if the difference is equal to between the two, it indicates that the battery is not sufficiently combusted, and a warning signal may be output to remind the user that the working state of the battery is abnormal.

Referring to fig. 8, the method for opening the serial number information of the adjacent connection port of the serial number information of the previous middle battery and feeding water into the serial number information of the water inlet pipeline corresponding to the serial number information of the end battery according to the main water feeding speed information includes:

step 700: and performing matching analysis according to the flow velocity information and the theoretical inlet water temperature information stored in the flow database, the heat generation efficiency information of the battery and the surface temperature information of the fuel cell to determine the theoretical inlet water temperature information, the heat generation efficiency information of the battery and the flow velocity corresponding to the surface temperature information of the fuel cell, and defining the flow velocity as the tail end flow velocity information.

The terminal flow rate information is information of flow rate required for water outlet according to a temperature threshold when water enters according to theoretical inlet water temperature information and heat exchange is carried out between the terminal flow rate information and a fuel cell of which the shell surface temperature is fuel cell shell surface temperature information and the exchanged heat is battery heat generation efficiency information.

Step 701: and calculating a difference value according to the intermediate flow rate information of the tail end flow rate information and the previous intermediate battery number information, and defining the difference value as flow rate difference value information.

The flow rate difference information is the difference between the terminal flow rate information and the intermediate flow rate information of the previous intermediate battery number information, and the calculation mode is subtraction of the terminal flow rate information and the intermediate flow rate information.

Step 702: and calculating rising speed information according to the main pipe water inlet speed information, the flow speed difference information and the preset water storage chamber section information.

The water storage chamber section information is information of a horizontal section of the water storage chamber. The rising speed information is information on the speed at which the water level in the water storage chamber rises. The calculation mode is that the water inlet speed information of the main pipe on the flow velocity difference information frame is divided by the interface information of the water storage chamber.

Step 703: and calculating the rising time information according to the full cavity height information and the rising speed information.

The rise time information is time information from the no water level information to the full cavity level information. The way of calculation is the full cavity height information divided by the ramp rate information.

Step 704: and when the water level height information is equal to the waterless height information, maintaining the adjacent connector number information of the previous middle battery number information closed, closing the water inlet number information corresponding to the tail end battery number information after the water inlet pipeline number information corresponding to the tail end battery number information rises for the time corresponding to the water inlet state rising time information of the main pipe water inlet speed information.

The water inlet number information is information of the opening end of the cooling branch pipe which enters the corresponding battery from the water storage chamber. When the adjacent connector number information and the water inlet number information are closed and the water inlet pipeline number information is opened, only the water entering the cooling main pipe does not flow out, the water temperature at the moment is the lowest, then as shown in fig. 2, the cooling main pipe is positioned above, and the water is positioned at the lower side of the water storage chamber due to the action of gravity.

Step 705: and opening the water inlet number information corresponding to the terminal battery number information when the water level height information is equal to the full cavity height information after the adjacent connector number information of the previous middle battery number information is opened.

As shown in fig. 2, since the pipe line of the adjacent connection port number information is located at the lower side, when the adjacent connection port number information of the previous intermediate battery number information is opened, the corresponding water flows into the water storage chamber, and since the water in the water storage chamber is the water of the cooling main pipe, the water flowing in from the adjacent connection port number information moves upward because the temperature of the water is higher than that of the water of the cooling main pipe, and the water of both temperatures is mixed uniformly. When the water in the water storage cavity is full, the water storage cavity and the water storage cavity are mixed sufficiently and in proper proportion, the water temperature is equal to the temperature of the theoretical inlet water temperature information, the water inlet number information corresponding to the terminal battery number information is opened, and the outlet water temperature of the terminal battery number information can be equal to the temperature threshold value.

It should be noted that the water inlet of the water inlet pipeline number information of the cooling main pipe is stopped at this time.
