The following examples are provided only for illustrating the present invention and are not intended to limit the scope of the present invention.
Unless otherwise specified, the technical means used in the examples of the present invention are conventional means well known to those skilled in the art.
The first embodiment is as follows:
referring to fig. 1 and 2, a fuel cell watering lorry power system heat radiation structure, including automobile body 19, automobile body 19's right side upper end is provided with water pitcher 1, there is water pump 2 water pitcher 1's left end one side through water piping connection, water pump 2's one end is connected with heat exchanger structure 3 through the connecting pipe, heat exchanger structure 3's left end is connected with fuel cell system 20, fuel cell system is connected 20's upper end one side and is connected with on-vehicle hydrogen storage system 21, fuel cell system 20 includes radiator 4, water tank 5, water pump two 7, thermostat 8, valve one 9 and fuel cell pile 6, water pitcher 1, water pump 2, heat exchanger structure 3 constitute a cooling main loop jointly, radiator 4, water tank 5, water pump two 7, thermostat 8, valve one 9 constitutes a cooling loop of fuel cell pile 6.
In this embodiment, the radiator 4 is provided with a radiator fan, a flow channel on one side of the heat exchanger structure 3 is connected in series with the cooling water circulation of the fuel cell system 20, and a flow channel on the other side of the heat exchanger structure 3 is connected to a water pump.
In this embodiment, the internal cooling water of the fuel cell system 20 is separated from the water in the water tank 1 by the heat exchanger structure 3, and the fuel cell system 20 further includes a second radiator 10, a second water tank 11, a third water pump 15, a second thermostat 16, and a second valve 17.
In this embodiment, the auxiliary components in the fuel cell system 20 mainly include a DC/DC converter 12, an air compressor 13, and a motor 14, and a cooling loop of the auxiliary components of the fuel cell system is composed of a second radiator 10, a second water tank 11, a third water pump 15, a second thermostat 16, and a second valve 17.
When the fuel cell sprinkler is started, the temperature of the power system is low, the main valve of the thermostat is closed, the cooling liquid directly returns to the water tank after passing through the water pump, the cooling liquid does not pass through the cooling circuit at the moment, the heat dissipation capacity of the power system is small, the temperature rise is fast, the cooling liquid flowing out of the water pump II 7 returns to the water tank 5 from the cooling circuit 1.1 after passing through the thermostat 8, and the cooling liquid flowing out of the water pump III 15 returns to the water tank II 11 from the cooling circuit 2.1 after passing through the thermostat II 16.
With the continuous operation of the fuel cell sprinkler power system, the system temperature continuously rises, when the temperature of the cooling liquid flowing out of the water pump II 7 reaches above a threshold value (80 ℃), a main valve of the thermostat 8 is started, the cooling loop 1.1 is closed, the cooling liquid enters the cooling loop 1.3 after passing through the thermostat 8, and heat is exchanged with water in the cooling main loop in the heat exchanger structure 3. At the same time, the water pump 2 is started, drawing water stored in the water tank 1, and injecting it into the heat exchanger structure 3, exchanging heat with the cooling liquid in the cooling circuit 1.3. At this time, the sufficient water amount in the water tank 1 can produce good heat dissipation effect, the radiator 4 is not needed, and the first valve 9 is in a closed state.
When the fuel cell sprinkler works, water in the water tank 1 is continuously sprayed outwards, and the heat dissipation effect of the cooling main loop is gradually weakened. When the temperature of the coolant flowing from the second water pump 7 rises further to above 85 ℃, the valve 9 is actuated, and part of the coolant flows through the cooling circuit 1.2, dissipating heat into the air in the radiator 4. Meanwhile, the fan of the radiator 4 is started, the heat dissipation capacity of the radiator 4 is increased, and the temperature stability of the fuel cell stack is kept.

When the temperature of the cooling liquid further rises to above 85 ℃, the fan of the second radiator 10 is started, the heat dissipation capacity of the second radiator 10 is increased, and the temperature of the auxiliary components of the fuel cell system is kept stable.
When the fuel cell watering cart runs at idle speed or low speed, the heating value of the power system is small, and the temperature of the system is gradually reduced. When the temperature of the coolant flowing from the second water pump 7 is lower than the threshold value (80 ℃), the first valve 9 is closed, and the coolant passes through the cooling circuit 1.3 only, exchanging heat with the water in the main cooling circuit in the heat exchanger structure 3. When the coolant temperature further drops below 70 ℃, the main valve of the thermostat 8 is closed and the coolant returns to the water tank 5 after passing through the cooling circuit 1.1. At the same time, the water pump 2 is turned off and the main cooling circuit is turned off.
When the temperature of the coolant flowing out of the third water pump 15 is lower than the threshold value (80 ℃), the fan of the second radiator 10 is turned off, and the heat radiation amount is reduced. When the temperature of the coolant further drops below 70 ℃, the main valve of the second thermostat 16 is closed, and the coolant returns to the second water tank 11 after passing through the cooling circuit 2.1.

In this embodiment, the radiator 4 is provided with a radiator fan, a flow channel on one side of the heat exchanger structure 3 is connected in series with the cooling water circulation of the fuel cell system 20, and a flow channel on the other side of the heat exchanger structure 3 is connected to a water pump.
In this embodiment, the internal cooling water of the fuel cell system 20 is separated from the water in the water tank 1 by the heat exchanger structure 3, and the fuel cell system 20 further includes a second radiator 10, a second water tank 11, a third water pump 15, a second thermostat 16, and a second valve 17.
In this embodiment, the auxiliary components in the fuel cell system 20 mainly include a DC/DC converter 12, an air compressor 13, and a motor 14, and a cooling loop of the auxiliary components of the fuel cell system is composed of a second radiator 10, a second water tank 11, a third water pump 15, a second thermostat 16, and a second valve 17.

In this embodiment, the second heat exchanger structure 18 and the heat exchanger structure 3 may provide a cold source for the auxiliary components of the fuel cell system and the fuel cell stack 6.
When the fuel cell sprinkler is started: the temperature of the power system is low, the main valve of the thermostat is closed, and the cooling liquid directly returns to the water tank after passing through the water pump. At the moment, the cooling liquid does not pass through the cooling loop, so that the heat dissipation capacity of the power system is small, and the temperature rise is fast. The coolant flowing out of the second water pump 7 passes through the thermostat 8 and then returns to the water tank 5 from the cooling circuit 1.1. The coolant flowing out of the third water pump 15 passes through the second thermostat 16 and then returns to the second water tank 11 from the second cooling circuit 2.1.
As the fuel cell sprinkler power system continues to operate, the system temperature continues to rise. When the main valve of any thermostat in the system is started, the water pump 2 needs to be started at the same time to supply water stored in the water tank 1 for the heat exchanger.
When the temperature of the coolant flowing out of the second water pump 7 reaches a threshold value (80 ℃) or higher, the main valve of the thermostat 8 is started, and the cooling circuit 1.1 is closed. The cooling liquid enters the cooling circuit 1.3 after passing through the thermostat 8, exchanging heat with the water in the cooling main circuit in the heat exchanger structure 3. At this time, the radiator 4 is not used, and the first valve 9 is in a closed state.
When the temperature of the coolant flowing out of the third water pump 15 reaches a threshold value (80 ℃) or higher, the main valve of the second thermostat 16 is opened, and the cooling circuit 2.1 is closed. The coolant passes through the second thermostat 16 and enters the cooling circuit 2.3 where it exchanges heat with the water in the main cooling circuit in the second heat exchanger 18. At this time, the second radiator 10 is not used, and the second valve 17 is in a closed state.
When the fuel cell sprinkler works, water in the water tank 1 is continuously sprayed outwards, and the heat dissipation effect of the cooling main loop is gradually weakened. When the temperature of the coolant flowing from the second water pump 7 rises further to above 85 ℃, the valve 9 is actuated, and part of the coolant flows through the cooling circuit 1.2, dissipating heat into the air in the radiator 4. Meanwhile, the fan of the radiator 4 is started, the heat dissipation capacity of the radiator 4 is increased, and the temperature stability of the fuel cell stack is kept.
When the temperature of the coolant flowing from the third pump 16 has increased to above 85 c, the valve 17 is actuated and part of the coolant flows through the cooling circuit 2.2, dissipating heat into the air in the second radiator 10. Meanwhile, the fan of the second radiator 10 is started, the heat dissipation capacity of the second radiator 10 is increased, and the temperature stability of the auxiliary components of the fuel cell system is kept.
When the fuel cell watering cart runs at idle speed or low speed, the heating value of the power system is small, and the temperature of the system is gradually reduced. When the temperature of the coolant flowing from the second water pump 7 is lower than the threshold value (80 ℃), the first valve 9 is closed, and the coolant passes through the cooling circuit 1.3 only, exchanging heat with the water in the main cooling circuit in the heat exchanger structure 3. When the coolant temperature further drops below 70 ℃, the main valve of the thermostat 8 is closed and the coolant returns to the water tank 5 after passing through the cooling circuit 1.1.
When the temperature of the coolant flowing from the third pump 15 is below a threshold value (80 c), the second valve 17 is closed and the coolant passes only through the second cooling circuit 2.3, exchanging heat with the water in the main cooling circuit in the second heat exchanger 18. When the temperature of the coolant further drops below 70 ℃, the main valve of the second thermostat 16 is closed, and the coolant returns to the second water tank 11 after passing through the cooling circuit 2.1.
When the main valves of the thermostat 8 and the second thermostat 16 are both closed, the water pump 2 is turned off and the main cooling circuit is closed.
