[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] At present, some marine power battery compartments use air conditioning or fans for cooling, but these two consume too much energy, and excessive power consumption affects the ship's endurance.

[0027] Based on this, the embodiments of the present invention provide a marine power battery compartment cooling system and method, which can reduce equipment energy consumption and improve the cooling effect.

[0028] To facilitate understanding of this embodiment, a marine power battery compartment cooling system disclosed in an embodiment of the present invention is first introduced in detail. Figure 1 The schematic structural diagram of a marine power battery cabin cooling system shown in the figure illustrates that the system mainly includes the following parts: a battery cabin wall 1, a sloping cabin roof 2, a top water tank 3, a booster pump 4 and a water pipe 5; wherein, the top water tank 3 is arranged on the top of the sloping cabin roof 2, and small holes are arranged around and on the bottom of the top water tank 3; the booster pump 4 supplies water to the top water tank 3 through the water pipe 5, and the water flow of the top water tank 3 is injected into the sloping cabin roof 2 through the small holes, and flows into the water through the battery cabin wall 1.

[0029] Furthermore, the above system also includes: a water guide groove 6, which is arranged on the deck of the ship; after the water in the top water tank 3 flows into the water guide groove 6 through the battery compartment wall 1, the water is discharged into the water through the water guide groove 6.

[0030] In one embodiment, the top water tank 3 is supplied with water by a small booster pump 4 through a water pipe 5. When the water tank needs a larger water flow to supply to the inclined cabin top 2, the booster pump 4 can provide a certain pressure to the top water tank 3 to ensure that the water flow meets the demand; see Figure 2 As shown, the top water tank 3 has one or two layers of small holes at the bottom of the four sides. The water in the top water tank 3 is injected into the inclined cabin top 2 through the small holes. There are fine water grooves on the inclined cabin top 2, which can increase the contact area between the water flow and the inclined cabin top 2, so as to take away more heat from the marine power battery cabin; the water flows through the inclined cabin top 2 to all directions, and then flows into the water guide groove 6 on the deck through the battery cabin wall 1, and then discharged into the water.

[0031] In the above-mentioned marine power battery compartment cooling system provided by an embodiment of the present invention, the booster pump supplies water to the top water tank through a water pipe, and the water flow in the top water tank is injected into the inclined cabin top through a small hole, and flows into the water through the battery cabin wall. The water flow can take away the heat of the marine power battery compartment when passing through the inclined cabin top and the battery cabin wall, thereby reducing the temperature of the marine power battery compartment. The above-mentioned cooling system can reduce the energy consumption of the equipment and improve the cooling effect at the same time.

[0032] In one embodiment, the above-mentioned marine power battery compartment cooling system also includes: a temperature sensor and a controller, wherein the temperature sensor is arranged inside the marine power battery compartment to collect the current temperature of the marine power battery compartment; the controller is used to obtain the current temperature of the marine power battery compartment collected by the temperature sensor, and send a first control signal to the boost pump according to the current temperature of the marine power battery compartment to control the speed of the boost pump.

[0033] In one embodiment, the controller is specifically used to: calculate the temperature difference between the current temperature and the target temperature of the marine power battery compartment; send a first control signal to the boosting pump according to the temperature difference to control the speed of the boosting pump. In specific implementation, if the temperature difference is greater than the first temperature threshold, a speed increase control signal is sent to the boosting pump to control the speed of the boosting pump to increase; if the temperature difference is greater than or equal to the second temperature threshold and less than or equal to the first temperature threshold, a speed constant control signal is sent to the boosting pump to control the speed of the boosting pump to remain unchanged; wherein, the first temperature threshold is greater than the second temperature threshold; if the temperature difference is less than the second temperature threshold, a speed reduction control signal is sent to the boosting pump to control the speed of the boosting pump to decrease.

[0034] In a possible implementation, the above-mentioned marine power battery compartment cooling system can control the cooling effect by adjusting the water pump flow rate and the top box pressure. Specifically, a high-precision temperature sensor is installed in the marine power battery compartment, and the temperature sensor can measure the current temperature in the marine power battery compartment in real time and send the data to a controller, such as a central processing unit or a microcontroller; the temperature data can be transmitted to the controller through a communication protocol (such as CAN bus, RS485, Wi-Fi, etc.).

[0035] Assuming that the current temperature in the marine power battery compartment is Tc, it is necessary to keep it within the target temperature To range. After the system is started, the initial speed of the boost pump can be set first, and then the data of the temperature sensor is read once every period of time (such as every second), and the temperature difference ΔT=Tc-To between the current temperature and the target temperature is calculated. If the temperature difference ΔT is greater than the first temperature threshold, it is considered that the current temperature of the marine power battery compartment is too high, and the cooling rate needs to be accelerated. A speed increase control signal is sent to the boost pump to control the speed of the boost pump to increase, thereby increasing the speed of adding water to the top water tank, thereby increasing the pressure of the top water tank, and accelerating the top water tank. The speed at which the internal water flow is injected into the top of the inclined tank; if the temperature difference ΔT is greater than or equal to the second temperature threshold and less than or equal to the first temperature threshold, it is considered that the current temperature of the marine power battery compartment is within the target temperature range and the status quo can be maintained, that is, a speed-constant control signal is sent to the boost pump to control the speed of the boost pump to remain unchanged; if the temperature difference is less than the second temperature threshold, it is considered that the current temperature of the marine power battery compartment is too low and the cooling intensity needs to be reduced, and a speed-reducing control signal is sent to the boost pump to control the speed of the boost pump to decrease, thereby slowing down the speed of adding water to the top water tank, thereby reducing the pressure in the top water tank, and slowing down the speed at which the water flow in the lower water tank is injected into the top of the inclined tank.

[0036] The above-mentioned marine power battery cabin cooling system provided by the embodiment of the present invention is provided by a booster pump supplying water to the top water tank through a water pipe, and the water flow in the top water tank is injected into the inclined cabin top through a small hole, and flows into the water through the battery cabin wall. The water flow can take away the heat of the marine power battery cabin when passing through the inclined cabin top and the battery cabin wall. The booster pump in the above-mentioned system has low power, low energy consumption, low noise, no harmful emissions, energy saving and environmental protection, reducing equipment energy consumption while improving the cooling effect.
