The fuel cell cooling unit 110 is used to exchange heat with the fuel cell; the first thermostat 210 has an input port and first and second output ports, the input port of the first thermostat 210 being connected to the output port of the fuel cell cooling unit 110; the heat exchanger 220 is provided with a first input port, a second input port, a first output port and a second output port, the first input port of the heat exchanger 220 is connected with the first output port of the first thermostat 210, the second input port of the heat exchanger 220 is used for inputting high-temperature gas generated by the air conditioner 600, the first output port of the heat exchanger 220 is used for outputting high-temperature gas generated by the air conditioner 600, and the second output port of the heat exchanger 220 is connected with the second output port of the first thermostat 210; the input port of the water pump 120 is connected to the second output port of the first thermostat 210, and the output port thereof is connected to the input port of the fuel cell cooling unit 110; the temperature sensor group 310 is at least used for detecting the temperature of the cooling liquid flowing through the first thermostat 210; the control unit 400 is electrically connected to the first thermostat 210, the water pump 120, and the temperature sensor group 310, respectively.
Referring to fig. 1 to 4, a fuel cell cooling unit 110 is disposed at a rear portion of a cabin of a fuel cell vehicle, and a water pump 120 is disposed at one side of the fuel cell cooling unit 110 and connected to the fuel cell cooling unit 110. The top of the fuel automobile is provided with an air conditioner 600, the heat exchanger 220 is connected with an air conditioner compressor 610 of the air conditioner 600 and is connected with the fuel cell cooling unit 110 through a pipeline, the heat exchanger 220 can be a plate heat exchanger, and the first thermostat 210 is connected in the pipeline. The first temperature sensor 311 of the temperature sensor group 310 may be disposed on a pipeline where the first thermostat 210 is located, and is used to collect temperature information of the cooling liquid in the first thermostat 210. The control unit 400 is used to receive feedback from the sensors and perform various control functions, for example, the control unit 400 may control the water pump 120, the first thermostat 210, the air conditioner compressor 610, and other components to be turned on and off.
In a low temperature environment, the hot air conditioner in the fuel vehicle is turned on, and at this time, the control unit 400 sends a signal to turn on the air conditioner compressor 610, so that the air conditioner compressor 610 generates high temperature gas. The water pump 120 pressurizes the coolant in the fuel cell cooling unit 110 to enable the coolant to circulate through the thermal management system. When the coolant flows to the first thermostat 210, the temperature sensor group 310 detects the temperature of the coolant and converts the temperature information into an electrical signal to be transmitted to the control unit 400. When the detected temperature of the cooling liquid does not reach the target temperature, the control unit 400 sends a driving signal to the first thermostat 210, so that the first thermostat 210 opens a first output port of the first thermostat, a part of the cooling liquid in the pipeline and high-temperature gas generated by the air conditioner compressor 610 flow into the heat exchanger 220 to exchange heat, and the temperature of the cooling liquid is rapidly increased. The warmed coolant flows out of the heat exchanger 220 and then meets the unheated coolant in the main pipeline, the temperature sensor group 310 detects the temperature of the coolant after meeting, and when the detected temperature of the coolant reaches a target temperature, the coolant flows back to the fuel cell cooling system, so that the temperature of the fuel cell stack can be rapidly raised, the electrochemical reaction in the fuel cell is accelerated, and the cold start of the engine is realized. Compared with the cold start only by the PTC heater of the fuel cell system, the heat management system of the embodiment of the utility model can greatly shorten the start time of the fuel cell automobile.
It should be noted that, for the optimum temperature for cold start of the fuel cell vehicle, the coolant temperature is generally between 60 and 70 degrees celsius, so the target temperature may be set to the minimum value of 60 degrees celsius or to the median value of 65 degrees celsius in this interval. When the temperature of the coolant is lower than 60 degrees celsius or higher than 70 degrees celsius, the flow rate of the part of the coolant flowing into the heat exchanger 220 can be increased or decreased by adjusting the opening of the first thermostat 210, so that the temperature of the coolant after intersection can be stabilized in the range of 60 to 70 degrees celsius all the time, thereby ensuring that the engine can be started by a cold engine.
In addition, in some embodiments, the thermal management system of the fuel cell vehicle further includes a filter 160, an intercooler 170, a deionizer 180, and an expansion tank 190. Referring to fig. 2 and 3, a filter 160 is connected to the main line for filtering impurities in the coolant. An intercooler 170 is connected between the input and output of the fuel cell cooling unit 110 for reducing the temperature of the pressurized air to a reasonable range of the temperature of the air entering the fuel cell stack. The deionizer 180 is connected between the outlet of the fuel cell cooling unit 110 and the expansion tank 190, and is used for removing conductive ions in the cooling liquid, so that the thermal management system has better insulation.

In some embodiments of the present invention, the control unit 400 may be a single chip, ARM, DSP or PLC, and may specifically be a STM32 series processor.
In some embodiments of the present invention, as shown in fig. 3 and 4, the thermal management system of the fuel cell vehicle further includes a second thermostat 510 and a first heat dissipation unit 520 electrically connected to the control unit 400. The second thermostat 510 has an input port and a first output port, a second output port, the input port of the second thermostat 510 is connected with the second output port of the first thermostat 210, the second output port of the second thermostat 510 is connected with the input port of the water pump 120; the input port of the first heat dissipation unit 520 is connected to the first output port of the second thermostat 510, and the output port of the first heat dissipation unit 520 is connected to the second output port of the second thermostat 510.
Specifically, a room temperature detection unit is arranged in a carriage of the fuel cell automobile and used for measuring the room temperature of the carriage, and the room temperature detection unit can adopt an infrared temperature sensor, a thermistor and the like. When the room temperature is low, the room temperature detecting unit converts the temperature information into an electrical signal and sends the electrical signal to the control unit 400, the control unit 400 thereby sends a heating demand signal to the second thermostat 510, and the second thermostat 510 thereby opens the first outlet thereof, so that the coolant heated by using the heat exchanger 220 flows into the first heat radiating unit 520. The first heat dissipation unit 520 exchanges heat between the cooling liquid and the indoor air to raise the room temperature to a comfortable temperature. Compared with the traditional automobile which is additionally provided with a PTC electric heater, a fuel oil heater, an air-conditioning heat pump or an air-conditioning PTC to supply warm air, the thermal management system of the fuel cell automobile provided by the embodiment of the utility model recycles the redundant heat generated by the fuel cell to supply heat, so that on one hand, the fuel cell automobile is not required to be additionally provided with a redundant heating device, the cost of the whole automobile is reduced, and the economical efficiency is improved; on the other hand, the problem of energy waste of the current fuel cell automobile is also solved, and the energy conservation, emission reduction, low carbon and environmental protection are facilitated.
In some embodiments of the present invention, as shown in fig. 3 and 4, the fuel cell vehicle thermal management system further includes a coolant flow meter 320 electrically connected to the control unit 400, wherein the coolant flow meter 320 is configured to detect a flow rate of the coolant flowing through the first heat dissipation unit 520. The coolant flow meter 320 may be connected in the pipe in which the first heat radiating unit 520 is located.
In some embodiments of the present invention, as shown in fig. 3, the temperature sensor group 310 includes a first temperature sensor 311, a second temperature sensor 312, and a third temperature sensor 313, all of which are electrically connected to the control unit 400.

The flow rate and temperature of the coolant flowing through the first heat dissipating unit 520 are detected by the coolant flow meter 320 and the temperature sensor group 310, so that the opening degree of the second thermostat 510 can be adjusted according to the flow rate and temperature information. The opening degree of the second thermostat 510 is adjusted so that the amount of heat radiated by the first heat radiation unit 520 is within an appropriate range. For example, when the room temperature of the vehicle cabin is lower than 5 degrees celsius, the opening degree of the second thermostat 510 may be adjusted to be larger, so that the first heat dissipation unit 520 dissipates more heat from the coolant to perform heating; when the room temperature of the vehicle cabin is higher than 18 ℃, the opening degree of the second thermostat 510 can be reduced or even closed, so that the heat emitted by the first heat dissipation unit 520 is reduced or even does not generate heat. Therefore, the opening degree of the second thermostat 510 is adjusted by monitoring the temperature and the flow rate in real time, so that the heating temperature is in a balanced and stable state.
In some embodiments of the present invention, as shown in fig. 3, the temperature sensor set 310 further includes a fourth temperature sensor 314 and a fifth temperature sensor 315, both of which are electrically connected to the control unit 400. The fourth temperature sensor 314 is used to detect the temperature of the input port of the fuel cell cooling unit 110; the fifth temperature sensor 315 is used to detect the temperature of the second output port of the first thermostat 210. The fourth temperature sensor 314 and the fifth temperature sensor 315 can be disposed on the pipelines at the input port and the output port of the fuel cell cooling unit 110, which is beneficial to monitoring the temperature of the fuel cell stack in real time and ensuring proper temperature of the fuel cell stack.
In some embodiments of the present invention, as shown in fig. 2, the first heat dissipation unit 520 has a plurality, and the plurality of first heat dissipation units 520 are disposed in the fuel cell vehicle body. The first heat radiating unit 520 may employ a heating radiator, and a plurality of heating radiators may be disposed at both sides of the vehicle compartment. Specifically, as shown in fig. 2, two heating radiators are respectively disposed on both sides of the vehicle compartment, and four heating radiators are located to form four corners of a rectangle. By adjusting the switches of the plurality of first heat dissipation units 520, it is beneficial to adjust the heat required by the compartment according to the heating requirement. As shown in fig. 2, the four heating radiators are uniformly distributed to uniformly radiate heat in the cabin space, so that passengers do not feel too cold or too hot while riding in a car.
In some embodiments of the present invention, as shown in fig. 3 and 4, the thermal management system of the fuel cell vehicle further includes a third thermostat 130, a second heat dissipation unit 140, and a heater 150, all of which are electrically connected to the control unit 400. The third thermostat 130 has an input port, a first output port and a second output port, the input port of the third thermostat 130 is connected with the second output port of the first thermostat 210, and the second output port of the third thermostat 130 is connected with the input port of the water pump 120; an input port of the second heat dissipation unit 140 is connected with a first output port of the third thermostat 130, and an output port of the second heat dissipation unit 140 is connected with an input port of the water pump 120; the heater 150 is used for heating the cooling liquid flowing out of the second output port of the third thermostat 130.
As shown in fig. 3, the third thermostat 130, the second heat dissipation unit 140, and the heater 150 constitute a size cycle in the thermal management system. For example, when the cooling fluid flows through the heat exchanger 220, if the heat exchanger 220 or the air conditioner compressor 610 fails, the cooling fluid may obtain insufficient heat; or when the cooling fluid flows through the first heat dissipation unit 520, the heat is dissipated excessively. In both cases, the thermal management system will start a small cycle, and the control unit 400 sends a signal to turn on the heater 150 and connect the third thermostat 130 to the heater 150, and the cold fluid flowing back to the main circuit will flow into the heater 150 to heat it, so the small cycle will act to compensate the temperature of the coolant. When the temperature of the coolant for the small circulation is too high, the thermal management system starts the large circulation, and the control unit 400 sends a signal to enable the third thermostat 130 to communicate with the second heat dissipation unit 140 and start the second heat dissipation unit 140, so as to discharge the excessive heat in the coolant for the main pipeline, and therefore, the large circulation further ensures that the thermal management system works in a proper temperature range.
In some embodiments of the present invention, as shown in fig. 2, the second heat dissipating unit 140 has a plurality of first heat dissipating units 520 disposed in the fuel cell vehicle body. The second heat dissipation unit 140 may be an air-cooled radiator, and is disposed at both sides of the fuel cell cooling unit 110 in the vehicle compartment. The wind speed of the rotary machine is controlled to dynamically adjust the heat discharged by the second heat dissipation unit 140, so that the temperature of the cooling liquid can be adjusted. And a plurality of cooling radiators are adopted, so that the temperature of the cooling liquid can be accurately adjusted.
