The second external circulating water pipe is connected to the other end of the external circulating water heat exchange pipe in the heat exchanger.

[0008] A heat exchange medium is arranged in the heat exchanger shell of the heat exchanger, and the inner circulating water heat exchange pipeline and the outer circulating water heat exchange pipeline are both located in the heat exchanger shell.

[0009] An electric heater is arranged on the heat exchanger shell, the electric heater extends into the heat exchange medium, and the electric heater is connected to the control component.

[0016] The technical solution of the utility model is adopted, and the working principle and beneficial effects are as follows:

[0017] The battery compartment structure of a pure electric powered ship described in the utility model, when the structure is set, the battery pack is set on the ship. The battery compartment includes a cooling chamber and an internal cavity, the internal cavity is used to arrange the battery, the cooling chamber is connected to one end of the internal circulation water heat exchange pipe in the heat exchanger through the first internal circulation water pipeline, and the cooling chamber is connected to the other end of the internal circulation water heat exchange pipe in the heat exchanger through the second internal circulation water pipeline, so that an internal circulation system is formed between the cooling chamber of the battery compartment and the internal circulation water heat exchange pipe. The first external circulation water pipeline is connected to one end of the external circulation water heat exchange pipe in the heat exchanger, and the second external circulation water pipeline is connected to the other end of the external circulation water heat exchange pipe in the heat exchanger, so that an external circulation system is formed between the external circulation water heat exchange pipe and the external circulation water tank connected to the first external circulation water pipeline and the second external circulation water pipeline.

At this time, no temperature interference and adjustment are required. When the temperature sensor monitors that the actual water temperature in the second pipeline of the internal circulation water is lower than the set water temperature range, the control component controls the electric heater to start and the internal circulation water pump to start. At this time, the electric heater heats the heat exchange medium in the heat exchanger, and the heat exchange medium with increased temperature exchanges heat with the circulating water in the heat exchange pipeline of the internal circulation water. The heated water in the internal circulation system enters the cooling chamber, thereby heating the battery compartment, so that the actual water temperature in the second pipeline of the internal circulation water monitored by the temperature sensor is within the set water temperature range, and then the control component controls the electric heater to stop and the internal circulation water pump to stop. When the temperature sensor monitors that the actual water temperature in the second inner circulating water pipeline is higher than the set water temperature range, the control component controls the inner circulating water pump to start, controls the outer circulating water pump to start, the outer circulating water first valve to open, and the outer circulating water second valve to open. At this time, the cold water in the outer circulating water tank is sent to the outer circulating water heat exchange pipeline, and the outer circulating water heat exchange pipeline exchanges heat with the heat exchange medium in the heat exchanger, and the heat exchange medium temperature is reduced. The heat exchange medium with reduced temperature exchanges heat with the circulating water in the inner circulating water heat exchange pipeline. The water in the cooled inner circulating system enters the cooling chamber, thereby cooling the battery compartment, so that the actual water temperature in the second inner circulating water pipeline monitored by the temperature sensor is within the set water temperature range, and then the control component controls the inner circulating water pump to stop, controls the outer circulating water pump to stop, closes the outer circulating water first valve, and closes the outer circulating water second valve. In this way, the temperature of the battery compartment is effectively kept within the set temperature range, and condensation is prevented, which naturally avoids the adverse effects of condensation on the battery.

The cooling chamber 2 is connected to the other end of the internal circulation water heat exchange pipe 7 in the heat exchanger 6 through the second internal circulation water pipe 8. In this way, an internal circulation system is formed between the cooling chamber of the battery compartment and the internal circulation water heat exchange pipe 7. The first external circulation water pipe 9 is connected to one end of the external circulation water heat exchange pipe 10 in the heat exchanger 6, and the second external circulation water pipe 11 is connected to the other end of the external circulation water heat exchange pipe 10 in the heat exchanger 6. In this way, an external circulation system is formed between the external circulation water heat exchange pipe 10 and the external circulation water tank connected to the first external circulation water pipe 9 and the second external circulation water pipe 11. The control component 14 is the control unit of the entire structure. When the temperature sensor 15 monitors that the actual water temperature in the second inner circulating water pipeline 8 is within the set water temperature range, the control component 14 controls the inner circulating water pump 16, the electric heater 13 and the outer circulating water pump 18 to be in the off state. At this time, no temperature interference and adjustment are required. When the temperature sensor 15 monitors that the actual water temperature in the second inner circulating water pipeline 8 is lower than the set water temperature range, the control component 14 controls the electric heater 13 to start and the inner circulating water pump 16 to start.

In the above structure, the first external circulating water valve 19 and the second external circulating water valve 20 are opened and closed and the opening degree is adjusted under the control of the control component, so as to effectively supply a specific amount of cold water to reliably realize the cooling of the battery compartment.

[0027] When the temperature sensor 15 monitors the actual water temperature in the second inner circulating water pipe 8 within the set water temperature range, the control component 14 is configured to control the inner circulating water pump 16, the electric heater 13 and the outer circulating water pump 18 to be in a closed state. With the above structure, when the temperature of the battery compartment is normal, no temperature adjustment is required, and intervention is required when the temperature is too low or too high.

[0028] When the temperature sensor 15 monitors that the actual water temperature in the second internal circulating water pipeline 8 is lower than the set water temperature range, the control component 14 is configured to control the start of the electric heater 13 and the start of the internal circulating water pump 16. The above structure can conveniently and quickly heat the water in the internal circulation system according to the real-time temperature monitoring situation, thereby increasing the temperature of the battery compartment 1.

[0029] When the temperature sensor 15 monitors that the actual water temperature in the second inner circulating water pipeline 8 is higher than the set water temperature range, the control component 14 is configured to control the inner circulating water pump 16 to start, the outer circulating water pump 18 to start, the outer circulating water first valve 19 to open, and the outer circulating water second valve 20 to open.
