Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a cooling device for a new energy ship power system. Background Technology

[0002] With the global shipping industry's low-carbon transformation, new energy ships (such as pure electric, hydrogen fuel cell, and hybrid ships) have become the mainstream of development due to their zero / low emission characteristics. Their power systems (motors, battery packs, fuel cell stacks, etc.) generate a lot of heat during operation. If heat dissipation is not timely, it will lead to component performance degradation, shortened lifespan, and even safety hazards. Therefore, efficient cooling devices are the core components of the power systems of new energy ships.

[0003] However, existing cooling devices for new energy ship power systems are not convenient for cooling and recycling fresh water when using fresh water for cooling, and it is not convenient to protect the fresh water circulation, which is not conducive to the stable operation of the cooling device. Utility Model Content

[0005] To achieve the above objectives, one embodiment of this utility model provides a cooling device for a new energy ship power system, including a cooling circulating freshwater pipeline connected to the new energy ship power system. The cooling circulating freshwater pipeline is designed according to the actual structure of the new energy ship power system, so that it is laid close to the internal structural surface of the new energy ship power system that needs cooling, or laid on the surface of the new energy ship power system for heat transfer cooling. This ensures that the cooling freshwater pipeline and the internal components of the new energy ship power system do not interfere with each other, guaranteeing that both can operate normally. One end of the cooling circulating freshwater pipeline is fixedly installed with a freshwater... A circulating cooling water pump is fixedly installed on one side of the new energy vessel's power system and securely mounted to the vessel, ensuring that the pump does not interfere with the power system. A circulating water pipe is fixedly installed at one end of the pump at the bottom of the vessel. This pipe is designed and manufactured according to the vessel's structural design to ensure maximum coverage area that matches the vessel's dimensions. This provides sufficient circulation area to cool the water inside the pipe. The pipe is installed at the bottom of the vessel, ensuring it is underwater after launch. Heat exchange occurs between the water inside the vessel and the circulating water pipe, thus achieving the cooling of the circulating water. The circulating water pipe is used for cooling. The surface of the circulating water pipe is equipped with a mounting base to fix its position. One end of the mounting base is bolted to a high-strength disassembly and assembly frame that provides protection and support for the circulating water pipe. The structure of the high-strength disassembly and assembly frame is designed according to the structure of the new energy vessel, ensuring that it conforms to the overall structural design of the new energy vessel. This ensures that the use of the high-strength disassembly and assembly frame does not affect the overall performance of the new energy vessel and can protect the circulating water pipe underwater, guaranteeing the safety of the new energy vessel. A booster pump to enhance the flow of fresh water is fixedly installed at one end of the circulating water pipe. A cooling water tank for storing fresh water is fixedly installed at the other end of the booster pump. The booster pump and... The cooling water tanks are all fixed inside the new energy vessel's propulsion system and do not interfere with each other. The cooling water tanks and cooling circulating fresh water pipelines are fixedly installed. The cooling water tanks are equipped with level gauges to detect the water level inside. The level gauges are connected to a cooling control unit for signal processing and automated control. The cooling control unit is connected to an alarm for early warning. The cooling control unit can be connected to the new energy vessel's control system. The new energy vessel's propulsion system and control system perform functional and comprehensive control of the cooling control unit. All control structures and methods are conventional control structures and methods for new energy vessels.

[0006] Preferably, in any of the above schemes, the cooling circulating freshwater pipeline runs through and is in close contact with the new energy ship power system, the cooling water pump is located on one side of the new energy ship power system, and the cooling water pump and the cooling control unit are connected by a signal.

[0007] The above technical solution is adopted: the cooling circulating fresh water pipeline is made of copper, runs through the new energy ship power system (such as motor and battery pack) and is attached to the surface of the heat-generating components. It absorbs heat through forced convection. The cooling water pump is driven by the cooling control unit to deliver the heat-absorbing fresh water to the circulating water pipeline at a certain flow rate to achieve cooling of the power system.

[0008] Preferably, in any of the above schemes, both the cooling circulating freshwater pipe and the circulating water pipe are made of thermally conductive materials, and the circulating water pipe is located on one side of the new energy ship power system.

[0009] The above technical solution involves using aluminum bronze alloy circulating water pipes located below the waterline at the bottom of the ship, utilizing seawater or river water for heat exchange. Pipe supports (316L stainless steel) are bolted to the hull, providing support for the circulating water pipes, ensuring the stability of the pipeline under water flow impact, and improving heat exchange efficiency.

[0010] Preferably, as described in any of the above embodiments, the high-strength disassembly frame includes a disassembly base for support and fixation and a corrosion-resistant filter screen for water guidance and protection. The disassembly base is fixedly installed inside the new energy vessel by bolts. One end of the disassembly base is fixedly installed with a corrosion-resistant filter screen having several filter holes inside. A waterproof sealing gasket is provided between the disassembly base and the new energy vessel. The mounting tube is fixedly installed inside the disassembly base by bolts.

[0011] The above technical solution is adopted: the high-strength disassembly frame's disassembly base (Q345 steel) is fixed to the hull by a waterproof sealing gasket, and the outer corrosion-resistant filter screen prevents water plants, gravel and other debris from damaging the circulating water pipe. The disassembly base is bolted to the hull, and can be disassembled as a whole during maintenance, which facilitates cleaning and maintenance of the filter screen.

[0012] Preferably, in any of the above schemes, the booster pump and the cooling water tank are fixedly installed inside the new energy vessel, and both the booster pump and the cooling water tank are located on one side of the new energy vessel's power system. The cooling water tank has a water storage chamber for storing fresh water inside, and a sealing plug for sealing the water storage chamber is fixedly installed at one end of the cooling water tank.

[0013] The above technical solution is adopted: the booster pump pressurizes the fresh water cooled by the circulating water pipe and delivers it to the storage chamber of the cooling water tank. The inner wall of the water tank is coated with a heat insulation coating to reduce heat recovery. The booster pump and the cooling water pump are linked and controlled. When the fresh water temperature reaches the preset value, the pump will start automatically to ensure stable fresh water circulation pressure.

[0014] Preferably, in any of the above embodiments, the sealing plug includes a waterproof plug for blocking the water storage cavity and a protective rubber ring for sealing the waterproof plug. The waterproof plug is inserted into the interior of the cooling water tank, and a protective rubber ring is fixedly installed at one end of the waterproof plug. The protective rubber ring is located between the waterproof plug and the cooling water tank.

[0015] The above technical solution is adopted: the waterproof plug (silicone rubber) of the sealing plug is inserted into the water inlet of the cooling water tank, and the protective rubber ring forms a double seal to improve the waterproof level. When filling water, the waterproof plug is rotated to unlock, and reset after filling water, ensuring that the water storage cavity does not leak when the ship is rocking.

[0016] Preferably, in any of the above embodiments, the water level gauge is located inside the water storage chamber, and the alarm is fixedly installed on the top of the cooling water tank.

[0017] The above technical solution is adopted: the water level gauge monitors the water level in the storage chamber in real time. When the water level is lower than the minimum threshold, it sends a signal to the cooling control unit to trigger the alarm. At the same time, the cooling control unit links with the ship's freshwater supply system to automatically replenish water.

[0018] The cooling water pump draws fresh water from the cooling water tank, which absorbs heat from the power system through the cooling circulation fresh water pipeline. The heated fresh water flows into the circulation water pipe and exchanges heat with the external water through the pipeline below the waterline at the bottom of the ship to cool it down. The booster pump pressurizes the cooled fresh water and sends it back to the cooling water tank to complete the circulation. A high-strength disassembly frame supports rapid underwater disassembly, a corrosion-resistant filter screen prevents debris from damaging the circulation water pipe, and the protective rubber ring of the sealing plug ensures the water tank's airtightness. The water level gauge and alarm form a double protection to prevent the power system from overheating due to water shortage.

[0020] 1. A cooling circulating freshwater pipeline is installed to fit the surface of the new energy ship's power system structure to transport freshwater for cooling. The freshwater absorbs the heat generated by the new energy ship's power system through heat conduction. The heat-absorbing freshwater is then introduced into the waters where the ship is sailing through the circulating water pipeline, where heat exchange is used to re-cool the freshwater, facilitating its recycling. At the same time, mounting pipe seats and high-strength disassembly and assembly brackets are installed to protect the circulating water pipeline, preventing debris in the waters from approaching and damaging it. This effectively improves the safety and stability of the cooling device.
