Technical Field
[0001] This utility model relates to the field of energy storage equipment technology, and more specifically, to a containerized energy storage cabinet liquid cooling heat dissipation device. Background Technology
[0002] Containerized energy storage cabinets are energy storage devices that use containers as carriers to load auxiliary modules such as battery modules, energy storage converter modules, and battery management system modules. Batteries generate heat during operation, so the container needs to be cooled.
[0003] Liquid cooling systems face a severe condensation problem during actual operation, especially in high-temperature and high-humidity regions or seasons. Specifically, during operation, the cooling medium circulates within the metal pipes, causing a significant drop in the surface temperature of the pipes. When the temperature difference between the inside and outside of the storage compartment exceeds 10°C and the ambient air humidity is high, the air temperature rapidly drops below the dew point upon contact with the low-temperature metal pipe surface. Water vapor condenses on the metal pipe surface, forming condensation. This condensation cannot be discharged in time and accumulates inside the energy storage cabinet, gradually forming water. This water can easily seep into the battery compartment through gaps in pipe connections and equipment installation gaps, directly contacting critical components such as battery cells and electrical connectors. This not only degrades the insulation performance of electrical components, causing insulation failures, but in severe cases, it can also lead to short circuits in the battery cells, potentially inducing thermal runaway and other major safety accidents, seriously threatening the operational safety and stability of the energy storage cabinet. Based on these issues, we propose a containerized liquid cooling system for energy storage cabinets. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a containerized energy storage cabinet liquid cooling heat dissipation device to solve the problem that when the existing device is used in high temperature and high humidity areas, the surface of the liquid cooling pipeline is prone to condensation and water accumulation, which threatens the safety of the energy storage cabinet.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a containerized energy storage cabinet liquid cooling heat dissipation device, including an energy storage component, a circulating cooling component, and a condensation component; the energy storage component includes an energy storage container, a door is provided on one side of the energy storage container, and a condensate storage tank is provided at the bottom of the energy storage container; the circulating cooling component includes a coolant storage tank provided inside one side of the energy storage container, a circulating pump is provided at the bottom of the coolant storage tank, and the input end of the circulating pump is connected to the coolant storage tank, the output end of the circulating pump is provided with a circulating liquid pipe, and the end of the circulating liquid pipe is connected to the coolant storage tank, and the surface of the coolant storage tank is provided with cooling fins; the condensation component includes a condensation plate provided on the inner side wall of the energy storage container, and the circulating liquid pipe passes through the condensation plate, the part of the condensation plate inside the energy storage container is a condensation section, and the bottom of the condensation section extends into the condensate storage tank, both sides of the condensation section are provided with guide grooves, and the part of the condensation plate extending to the outside of the energy storage container is a heat dissipation section, and the surface of the heat dissipation section is provided with heat dissipation holes; When the temperature difference between the inside and outside of the energy storage container exceeds 10°C and the ambient air is humid, the water droplets condensed on the surface of the circulating liquid pipe and the condenser plate are collected in the guide groove on the surface of the condensation section and finally introduced into the condensate storage tank.
[0006] Preferably, the condenser plate has a multi-layered plate structure with continuous serpentine folding, and is formed by repeated bending along its extension direction to create continuous peaks and troughs.
[0007] Preferably, the circulating fluid pipe has a multi-layered meandering structure, consisting of multiple horizontal and vertical pipes connected sequentially by arc-shaped bends, forming a layered and reciprocating arrangement, with the horizontal pipes being higher on both sides and lower in the middle.
[0008] Preferably, the surface of the circulating fluid pipe is uniformly distributed with corrugated grooves, which form flow guiding channels on the surface of the circulating fluid pipe.
[0009] Preferably, the top of the energy storage container is provided with a heat dissipation window, and the inside of the heat dissipation window is provided with a dustproof net, and the condensate storage tank is provided with a drain valve on the side near the door.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs an energy storage component, a circulating cooling component, and a condensation component. A condensate collection tank is installed at the bottom of the energy storage container. Through the structural cooperation of the circulating liquid pipe and the condensation plate, a closed loop for condensation prevention and control is formed. The circulating liquid pipe is designed with high sides and low middle, which can guide the condensate on the pipe surface to concentrate in the middle with the help of gravity, preventing it from randomly dripping onto sensitive components such as battery cells and electrical connectors. The corrugated grooves on the pipe surface can form a directional flow channel to accelerate the collection of condensate, while also increasing the heat dissipation area to assist in cooling. The flow guide groove of the condensation section of the condensation plate can not only efficiently receive the condensate dripping from the circulating liquid pipe, but also collect the condensate on its own surface. The anti-overflow design can prevent the condensate from overflowing from the tank during the flow. Then, with the help of gravity, the condensate is accurately guided into the condensate storage tank, which greatly reduces the risk of thermal runaway and significantly improves the operational safety and stability of the energy storage cabinet.
[0011] 2. This utility model further designs the condenser assembly. The serpentine structure of the condenser plate, with its continuous peaks and troughs, provides multi-point support for the circulating liquid pipe, making the pipeline more stable and preventing displacement due to slight vibrations during operation. Simultaneously, it buffers the impact of bumps during container transport, reducing stress and wear at the circulating liquid pipe interfaces, effectively preventing loosening of the interfaces, and structurally reducing the probability of leakage, ensuring system sealing safety. Furthermore, the heat dissipation holes in the heat dissipation section significantly increase the contact area with outside air, accelerating airflow and heat exchange, quickly removing the condenser plate's own heat, and helping to lower its temperature. This allows the condenser plate to cool the circulating liquid pipe more efficiently, indirectly improving the heat dissipation efficiency of the entire liquid cooling system, achieving dual optimization of structural stability and heat dissipation performance, further ensuring the reliability of the energy storage cabinet.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: This utility model relates to a containerized energy storage cabinet liquid cooling heat dissipation device, including an energy storage component 1, a circulating cooling component 2, and a condensation component 3. The energy storage component 1 includes an energy storage container 101, with a door 102 rotatably connected to one side of the energy storage container 101. A condensate storage tank 103 is fixedly connected to the bottom of the energy storage container 101. The energy storage container 101 serves as a carrier, providing installation space for battery modules, energy storage converter modules, etc., forming a closed operating environment. It is the basic load-bearing structure of the entire heat dissipation device. The door 102 facilitates the opening for inspection, maintenance, or replacement of internal equipment. The condensate storage tank 103 is used to collect condensate water, preventing water from spreading randomly inside the compartment and blocking the contact path between water and the battery cells from the source. The circulating cooling component 2 includes a coolant storage tank 201 fixedly connected to one side of the energy storage container 101. A circulating pump 202 is fixedly connected to the bottom of the coolant storage tank 201, and the circulating pump 202 circulates the coolant. The input end of the circulating pump 202 is connected to the coolant storage tank 201. The output end of the circulating pump 202 is connected to the circulating liquid pipe 203, and the end of the circulating liquid pipe 203 is connected to the coolant storage tank 201. A cooling plate 204 is fixedly connected to the surface of the coolant storage tank 201. The coolant storage tank 201 is used to store the cooling medium, such as ethylene glycol solution, to provide a continuous source of coolant for the circulating cooling assembly 2, ensuring the supply of medium for heat dissipation circulation. The circulating pump 202 connects the coolant storage tank 201 and the circulating liquid pipe 203, and drives the coolant to flow in the circulating liquid pipe 203 through power to realize the circulation and heat exchange of the coolant, which is the power source for heat dissipation circulation. The circulating liquid pipe 203 is used to transport the coolant, and absorbs the heat generated by the battery operation when it flows through the inside of the energy storage cabinet. The cooling plate 204 is installed on the surface of the coolant storage tank 201, and reduces the temperature of the coolant in the tank through the cooling effect, ensuring that the coolant has sufficient heat absorption capacity and maintaining heat dissipation efficiency.The condensation assembly 3 includes a condensation plate 301 fixedly connected to the inner wall of the energy storage container 101, with a circulating liquid pipe 203 passing through the condensation plate 301. The portion of the condensation plate 301 inside the energy storage container 101 is a condensation section 302, with the bottom of the condensation section 302 extending into the condensate storage tank 103. Both sides of the condensation section 302 are provided with guide grooves 3021. The portion of the condensation plate 301 extending outside the energy storage container 101 is a heat dissipation section 303, with heat dissipation holes 3031 on its surface. The condensation plate 301 penetrates both inside and outside the energy storage container 101, supporting the circulating liquid pipe 203 on its inner side and guiding condensation, while assisting in heat dissipation on its outer side. The condensation section 302 directly contacts the interior of the container. High-temperature and high-humidity air condenses on its surface, and the resulting condensation is guided into the storage tank via the guide channel 3021. This is the core area for condensation collection. The guide channel 3021 forms directional channels on both sides of the condensation section 302, guiding the condensation to flow along the tank body and preventing it from dripping or flowing randomly. This ensures that the condensation flows accurately into the condensate storage tank 103. The heat dissipation section 303 is exposed to the external environment and lowers its own temperature through heat exchange with the air, indirectly enhancing the condensation collection capacity of the condensation section 302. At the same time, it assists the cooling circulation pipe 203. The heat dissipation holes 3031 increase the contact area between the heat dissipation section 303 and the outside air, accelerating air circulation and heat exchange, improving the heat dissipation efficiency of the heat dissipation section 303, and ensuring the overall performance of the condensation plate 301. Temperature stability; This utility model, through the design of energy storage component 1, circulating cooling component 2, and condensation component 3, has a condensate collection tank at the bottom of the energy storage container 101. Through the structural cooperation of the circulating liquid pipe 203 and the condensation plate 301, a closed loop for condensation prevention and control is formed. The circulating liquid pipe 203 is designed with higher sides and a lower middle section, which can guide condensation on the pipe surface to concentrate in the center by gravity, preventing it from randomly dripping onto sensitive components such as battery cells and electrical connectors. The corrugated grooves 2031 on the pipe surface can form a directional flow channel to accelerate condensation collection and also increase the heat dissipation area to assist in cooling. The guide grooves 3021 of the condensation section 302 of the condensation plate 301 can efficiently collect condensation dripping from the circulating liquid pipe 203, and also... It can collect condensation on its own surface, and the anti-overflow design prevents condensation from overflowing from the tank during flow. Then, gravity accurately guides the condensation into the condensate storage tank 103, which greatly reduces the risk of thermal runaway and significantly improves the safety and stability of the energy storage cabinet. This utility model also further designs the condensation component 3. The serpentine structure of the condensation plate 301, with its continuous peaks and troughs, can provide multi-point support for the circulating liquid pipe 203, making the pipeline more stable and preventing displacement due to slight vibration during operation. At the same time, it can buffer the impact of bumps during container transportation, reduce the stress and wear at the interface of the circulating liquid pipe 203, effectively prevent the interface from loosening, reduce the probability of leakage from the structural level, and ensure the sealing safety of the system.Furthermore, the heat dissipation holes 3031 of the heat dissipation section 303 significantly increase the contact area with the outside air, accelerating air circulation and heat exchange, quickly removing the heat from the condenser plate 301 itself, and helping to lower its temperature. This allows the condenser plate 301 to cool the circulating liquid pipe 203 more efficiently, indirectly improving the heat dissipation efficiency of the entire liquid cooling system. This achieves dual optimization of structural stability and heat dissipation performance, further ensuring the operational reliability of the energy storage cabinet.
[0015] Specifically, the condenser plate 301 has a multi-layered plate structure with continuous serpentine folding. It forms continuous peaks and troughs by repeatedly bending along its extension direction. The continuous peaks and troughs form multi-point support to firmly fix the circulating liquid pipe 203. At the same time, the structural elasticity is used to buffer the bumps during transportation, reduce the stress on the interface of the circulating liquid pipe 203, and prevent the interface from loosening.
[0016] More specifically, the circulating fluid pipe 203 has a multi-layered meandering structure, consisting of multiple horizontal and vertical pipes connected sequentially by arc-shaped bends, forming a layered and reciprocating arrangement. The horizontal pipes are set with higher sides and lower middle, increasing the flow path of the coolant in the chamber and improving the heat exchange area with the battery. The "higher sides and lower middle" design of the horizontal pipes uses gravity to guide the condensation on the pipe surface to collect in the middle, making it easier to drip onto the condenser plate 301.
[0017] It is worth mentioning that the surface of the circulating liquid pipe 203 is uniformly distributed with corrugated grooves 2031. The corrugated grooves 2031 form a flow guiding channel on the surface of the circulating liquid pipe 203, forming a continuous flow guiding channel on the pipe surface, which quickly receives and guides the flow of condensation, avoids condensation from stagnating on the pipe surface, and accelerates the condensation to gather in the middle of the pipe.
[0018] It is worth noting that the top of the energy storage container 101 is equipped with a heat dissipation window, and the inside of the heat dissipation window is equipped with a dustproof net. The heat dissipation window promotes air circulation between the inside and outside of the compartment, helps to dissipate heat from the compartment, and enhances the overall heat dissipation effect. The dustproof net prevents external dust from entering the energy storage cabinet, avoiding dust from adhering to the equipment surface and affecting heat dissipation or causing malfunctions. The condensate storage tank 103 is equipped with a drain valve 104 on the side near the door 102. The drain valve 104 can be opened periodically to drain the water collected in the storage tank, preventing water from overflowing and simplifying maintenance operations.
[0019] Working principle: This embodiment provides a containerized energy storage cabinet liquid cooling heat dissipation device. In use, the circulation pump 202 is started, and the coolant circulates in a closed loop in the circulation pipe 203. The cooling chip 204 is activated to cool the coolant in the coolant storage tank 201. When the coolant flows through the circulation pipe 203, it absorbs the heat generated by the battery in the energy storage cabinet. When the temperature difference between the inside and outside of the energy storage container 101 is large and the air is humid, water vapor in the air condenses on the surface of the circulation pipe 203 and the condenser plate 301 to form condensation. The condensation on the surface of the circulation pipe flows along the corrugated groove 2031 to the middle of the horizontal pipe and then drips onto the condensation section 302 of the condenser plate 301. The condensation on the surface of the condenser plate 301 flows downward along the guide groove 3021 and finally flows into the condensate storage tank 103. The heat dissipation section 303 of the condenser plate 301 exchanges heat with the outside air through the heat dissipation holes 3031, which helps to reduce the temperature of the condenser plate 301.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
