[0001] This utility model relates to the field of electrochemical energy storage technology, specifically to a split-type top-mounted air outlet heat dissipation energy storage system. Background Technology

[0002] In recent years, energy storage technology has developed rapidly in various industries, with increasing single-unit power density and faster charge and discharge rates. At a charge and discharge rate of 1C, the system has a capacity of 2.5MWh. Currently, the mainstream single container in the industry uses a single 60KW centralized liquid cooling unit for heat dissipation. However, due to limitations in size and cooling capacity, it cannot fully meet the needs of domestic and export markets.

[0003] Existing energy storage systems suffer from uneven and large temperature differences at the cluster level, and maintenance is inconvenient. When a single lithium iron phosphate pack or unit fails, the entire system coolant must be drained before maintenance can be performed. Utility Model Content

[0004] Therefore, this utility model provides a split-type top-mounted air outlet heat dissipation and energy storage system to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A split-type top-mounted air outlet heat dissipation and energy storage system includes:

[0007] The housing is internally divided into upper and lower compartments. The upper compartment is the top cooling system compartment, and the lower compartment is the electrical compartment. The electrical compartment is internally divided into left and right compartments. The left compartment is the battery compartment, and the right compartment is the electrical control compartment.

[0008] A battery assembly, wherein multiple sets of the battery assembly are arranged sequentially in a horizontal direction within the battery;

[0009] A liquid cooler is provided in the top cooling system compartment, and the liquid cooler includes multiple liquid cooling units, which are arranged in sequence in the horizontal direction in the top cooling system compartment. Each liquid cooling unit corresponds to and is connected to a battery module. An air outlet is provided at the top of the top cooling system compartment, and the air outlet is connected to the exhaust port of the liquid cooling unit.

[0010] A control component is located within the electrical control compartment and is electrically connected to the battery assembly.

[0011] Optionally, the battery assembly includes a high-voltage box and a lithium iron phosphate battery pack. The battery compartment is equipped with liquid cooling pipes, and there are multiple liquid cooling pipes, each corresponding to a lithium iron phosphate battery pack. The liquid cooling pipes are connected to the liquid cooling unit through stainless steel pipes in the box.

[0012] Optionally, the control system includes an AC power distribution cabinet, a DC combiner cabinet, and a fire-fighting gas spraying system.

[0013] Optionally, the front side of the enclosure is provided with a door, and there are multiple doors. Each door corresponds to a battery assembly. One door is equipped with a dehumidifying air conditioner, and another door is equipped with a fire-fighting ventilation system.

[0014] Optionally, each of the liquid cooling units is equipped with an exhaust duct assembly on top, and the exhaust port of the liquid cooling unit is connected to the air outlet of the top cooling system compartment through the exhaust duct assembly.

[0015] This utility model has at least the following beneficial effects:

[0016] This invention uses liquid coolers to divide the system into multiple small liquid cooler units with different power ratings. With proper and reasonable arrangement, each liquid cooler unit corresponds to a battery module. For energy storage systems with different power ranges, a single container can be compatible with various design schemes with different charge and discharge rates and can be combined with each other. Therefore, if a single liquid cooler unit fails and goes out of service, it will not affect the operation of other energy storage clusters. Attached Figure Description

[0029] like Figures 1-5 As shown, this utility model discloses a split-type top-mounted air outlet heat dissipation and energy storage system, comprising:

[0030] The housing 1 is internally divided into two accommodating chambers, the upper accommodating chamber being the top cooling system compartment 2, and the lower accommodating chamber being the electrical compartment. The electrical compartment is internally divided into two accommodating chambers, the left accommodating chamber being the battery compartment 3, and the right accommodating chamber being the electrical control compartment 4.

[0031] A battery assembly, wherein multiple sets of the battery assembly are arranged sequentially in a horizontal direction within the battery;

[0032] A liquid cooler is provided in the top cooling system compartment 2, and the liquid cooler includes multiple liquid cooling units 7, which are arranged in sequence in the horizontal direction in the top cooling system compartment 2. Each liquid cooling unit 7 corresponds to and is connected to a battery assembly. The top of the top cooling system compartment 2 is provided with an air outlet, which is connected to the exhaust port of the liquid cooling unit 7.

[0033] A control component is located inside the electrical control compartment 4 and is electrically connected to the battery assembly.

[0034] The aforementioned housing 1 is internally divided into two accommodating chambers, upper and lower, by a partition. The upper chamber is the top cooling system chamber 2, and the lower chamber is further divided into two accommodating chambers, left and right, with the battery chamber 3 on the left and the electrical control chamber 4 on the right. The specific dimensions of the top cooling system chamber 2, battery chamber 3, and electrical control chamber 4 are set according to the dimensions of the liquid cooling unit 7, battery pack, and control system.

[0035] Multiple sets of battery modules are arranged in the battery compartment 3, spaced apart in a horizontal direction. The spacing between the battery modules facilitates the design of the piping. A liquid cooler is installed in the top cooling system compartment 2. The liquid cooler includes multiple small liquid cooling units 7. The number of liquid cooling units 7 is the same as the number of battery modules. One liquid cooling unit 7 is installed above each battery module. The liquid cooling pipes 8 on the battery modules are connected to the liquid cooling units 7 through stainless steel pipes inside the housing 1.

[0036] The battery assembly includes a high-voltage box 9 and a lithium iron phosphate battery pack 10. A liquid cooling pipe 8 is provided in the battery compartment 3. There are multiple liquid cooling pipes 8, and each liquid cooling pipe 8 corresponds to a lithium iron phosphate battery pack 10. The liquid cooling pipes 8 are connected to the liquid cooling unit 7 through stainless steel pipes in the housing 1.

[0037] The battery compartment 3 houses its liquid cooling pipes 8, high-voltage box 9, and lithium iron phosphate battery pack 10. The liquid cooling pipes 8 are connected to the liquid cooling unit 7 through stainless steel pipes in the enclosure. The high-voltage box 9 is installed at the bottom of the lithium iron phosphate battery pack 10. The battery compartment 3 door panel is equipped with a dehumidifying air conditioner 6 and a fire-fighting air intake and exhaust system 5. The electrical control compartment 4 houses an AC distribution cabinet 12, a DC combiner cabinet 13, and a fire-fighting gas spray system 14. The liquid cooling unit 7 is installed in the top cooling system compartment 2, and each liquid cooling unit 7 has a top exhaust duct assembly 11 installed on its top.

[0038] The control system includes an AC power distribution cabinet 12, a DC combiner cabinet 13, and a fire-fighting gas spraying system 14.

[0039] The front side of the housing 1 is provided with a compartment door, and there are multiple compartment doors. Each compartment door corresponds to a battery component. One compartment door is equipped with a dehumidifying air conditioner 6, and another compartment door is equipped with a fire-fighting air intake and exhaust system 5.

[0040] Each of the liquid cooling units 7 is equipped with an exhaust duct assembly on its top, and the exhaust port of the liquid cooling unit 7 is connected to the air outlet of the top cooling system compartment 2 through the exhaust duct assembly.

[0041] The aforementioned exhaust duct assembly is a sheet metal structure installed around the exhaust port of the liquid chiller 7. The sheet metal structure connects the exhaust port and the outlet of the liquid chiller 7 to prevent cross-flow of air back to the inlet of the liquid chiller.

[0042] In the structural design of this utility model, redundancy can be incorporated while still meeting the system's cooling capacity requirements, allowing for future customer needs to be pre-planned within the container. The single high-power, high-flow liquid-cooled unit 7 is broken down into multiple smaller units of varying power. Through thorough and rational arrangement, a single container can accommodate various design schemes with different charge / discharge rates for energy storage systems of different power ranges. The liquid-cooled unit 7 can be universally configured with a cooling capacity of 4-8kW and can be combined with other units.

[0043] Multiple cooling units of different power are installed on the top of the container for precise control of each cluster. The cooling system controls the temperature of each cluster pack, and adjacent cluster packs do not interfere with each other, with the temperature difference between clusters controlled within 2 degrees.

[0044] If a single liquid-cooled unit 7 fails and is taken out of service, it will not affect the operation of other energy storage clusters.

[0045] Inside the container, the liquid cooling unit 7 operates independently on the top of the container, with the air outlet direction being top-out and front-in, which provides convenient conditions for daily maintenance.

[0046] The liquid cooling unit 7 exists independently from the control and fire protection systems. During normal operation and maintenance, it is relatively independent and will not affect the system.

[0047] The modular design allows the unit to be installed on top, which, while facilitating installation, can significantly improve the space utilization of containers, reduce processing costs, and meet the needs of high-cube shipping.

[0048] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0049] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0050] The present invention has been described in detail above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
