Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a container liquid cooling heat dissipation device. Background Technology

[0002] In the context of the current energy transition and renewable energy utilization, energy storage technology has received widespread attention. Especially in battery energy storage systems, effectively managing battery temperature to improve performance and lifespan has become a crucial issue. Liquid cooling technology, due to its excellent thermal conductivity and cooling efficiency, is gradually becoming the preferred solution for battery thermal management in energy storage cabinets. Containers, as the external structure of energy storage systems, can provide an excellent installation platform for liquid cooling devices. By integrating a highly efficient liquid cooling system inside the container, precise temperature control of the battery modules can be achieved, thereby optimizing the battery's operating state. Therefore, a containerized liquid cooling device is needed.

[0003] Traditional container liquid cooling systems typically use circulating coolant to directly remove heat generated by the battery, keeping it within its optimal operating temperature range. Over time, the coolant in the system gradually heats up as it absorbs heat from the battery. Once the coolant temperature exceeds a certain threshold, its heat transfer efficiency decreases significantly, resulting in poor heat dissipation. This temperature rise may lead to uncontrolled battery temperature, increasing the risk of overheating and affecting the system's safety and reliability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a container liquid cooling heat dissipation device.

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

[0006] A container liquid cooling heat dissipation device includes an outer casing, an inner casing inside the outer casing, and a cavity structure between the inner and outer casings. A door is installed at one end of the outer side wall of the outer casing, and a water tank is installed at the other end of the outer side wall. A cooling mechanism for cooling water is installed inside the water tank. A water supply mechanism for supplying water to the cavity is installed at the top of the outer casing. Return pipes are symmetrically installed through both outer side walls of the water tank, and one end of each return pipe communicates with the cavity. A one-way valve is installed on the outer side wall of each return pipe. A U-shaped tube is installed at the top of the inner casing, and multiple circular holes are evenly spaced at the bottom of the U-shaped tube. A serpentine tube is installed inside the water tank, and one end of the serpentine tube... The device runs through the interior of the outer casing, with one end of the serpentine tube connected to the loop tube. An air inlet pipe is fixed to the other end of the serpentine tube. A connecting box is fixed to one side of the top of the outer casing, with one end of the air inlet pipe passing through the connecting box. The connecting box contains an air filter, and the top of the outer casing has a blower mechanism for blowing air into the connecting box. During use, the cooling mechanism rapidly reduces the coolant temperature. Combined with a water supply mechanism, the coolant is pumped into the cavity between the outer and inner casings for circulation, ensuring the coolant remains at a low temperature. This effectively reduces the temperature of the inner casing, providing a better working environment for batteries and other equipment, and improving cooling efficiency.

[0007] Preferably, the water delivery mechanism includes a water pump, which is fixed to one end of the top of the outer casing. An outlet pipe is fixed to the inlet end of the water pump, and one end of the outlet pipe passes through the inner wall of the water tank. An inlet pipe is fixed to the outlet end of the water pump, and one end of the inlet pipe communicates with the cavity. The cooling mechanism includes a thermoelectric cooler. A mounting hole is provided on the outer wall of the water tank. The thermoelectric cooler is fixed to the side wall of the mounting hole. Multiple second fins are linearly fixed at equal intervals on the cold end of the thermoelectric cooler, and the hot end of the thermoelectric cooler is fixed at equal intervals. There are multiple first fins. When the semiconductor cooling chip is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple second fins to drop rapidly, thus cooling the coolant. At the same time, the water pump, in conjunction with the outlet and inlet pipes, draws the coolant into the cavity between the outer and inner tanks. When the cavity is full of coolant, the excess coolant flows back into the water tank through two return pipes and two one-way valves for recooling, ensuring that the used coolant is always kept at a low temperature. This maintains a low-temperature environment inside the inner tank and improves heat dissipation.

[0008] Preferably, the blower mechanism includes a fan fixed to the top of the outer casing, and the air outlet of the fan is connected to the connecting box. The filter mechanism includes multiple filter layers, all of which are fixed to the inner side wall of the connecting box and located between the fan and the air inlet pipe. The fan draws outside air into the connecting box, filters out dust and other impurities from the air through the multiple filter layers, and then enters the serpentine tube through the air inlet pipe. Since the serpentine tube is in coolant, its surface temperature is low. When air passes through the inside of the serpentine tube, its temperature is cooled. The cooled air eventually enters the U-shaped tube and is blown into the inner casing through multiple round holes. This achieves the effect of reducing battery temperature, slowing down battery aging, and extending battery life.

[0009] Preferably, the inner box has two symmetrical inner side walls with U-shaped plates installed, and one end of each U-shaped plate extends through the outer side wall of the outer box. Dustproof nets are fixed to the inner side walls of the two U-shaped plates. The heat generated by the battery during operation can be discharged to the outside of the outer box through the two U-shaped plates, while the two dustproof nets can prevent external dust from entering the inner box.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, this device can quickly reduce the temperature of the coolant through the cooling mechanism. In conjunction with the water supply mechanism, the coolant is pumped into the cavity between the outer and inner tanks for circulation, so that the coolant is always kept at a low temperature, thereby effectively reducing the temperature of the inner tank, providing a good working environment for batteries and other equipment, and improving cooling efficiency.

[0012] 2. The design of the filtration mechanism can effectively remove dust and other impurities from the air, ensuring the air quality entering the outer casing. At the same time, the contact between the serpentine tube and the coolant keeps the surface temperature of the serpentine tube low. When the filtered air passes through the serpentine tube, the air temperature decreases, and the cold air enters the serpentine tube and is blown into the inner casing through multiple round holes, further improving the heat dissipation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 - Figure 5 A container liquid cooling heat dissipation device includes an outer box 1, an inner box 20 inside the outer box 1, and a cavity structure between the inner box 20 and the outer box 1. A door 12 is installed at one end of the outer wall of the outer box 1, and a water tank 2 is installed at the other end of the outer wall of the outer box 1. A cooling mechanism for cooling water is installed inside the water tank 2. A water supply mechanism for supplying water into the cavity is installed at the top of the outer box 1. Return pipes 10 are symmetrically installed through the two outer walls of the water tank 2, and one end of each return pipe 10 is connected to the cavity. A one-way valve 11 is installed on the outer wall of each of the two return pipes 10. A U-shaped pipe 18 is installed at the top of the inner box 20, and multiple round holes 19 are equally spaced at the bottom of the U-shaped pipe 18. A serpentine pipe 17 is installed inside the water tank 2. The serpentine tube 17 extends through the inner casing 20, and one end of the serpentine tube 17 is connected to the loop tube 18. The other end of the serpentine tube 17 is fixed with an air inlet pipe 16. A connecting box 5 is fixed on one side of the top of the outer casing 1. One end of the air inlet pipe 16 extends through the interior of the connecting box 5. The connecting box 5 is equipped with a filter mechanism for filtering air. The top of the outer casing 1 is equipped with a blower mechanism for blowing air into the interior of the connecting box 5. During use, the device can quickly reduce the temperature of the coolant through the cooling mechanism. In conjunction with the water supply mechanism, the coolant is drawn into the cavity between the outer casing 1 and the inner casing 20 for circulation, so that the coolant is always kept at a low temperature, thereby effectively reducing the temperature of the inner casing 20, providing a good working environment for batteries and other equipment, and improving cooling efficiency.

[0021] Furthermore, the water delivery mechanism includes a water pump 7, which is fixed to one end of the top of the outer casing 1. An outlet pipe 8 is fixed to the inlet end of the water pump 7, and one end of the outlet pipe 8 penetrates the inner wall of the water tank 2. An inlet pipe 9 is fixed to the outlet end of the water pump 7, and one end of the inlet pipe 9 communicates with the cavity. The cooling mechanism includes a semiconductor cooling chip 13. An installation hole is provided on the outer wall of the water tank 2. The semiconductor cooling chip 13 is fixed to the side wall of the installation hole. Multiple second fins 15 are fixed linearly at equal intervals on the cold end of the semiconductor cooling chip 13, and multiple first fins are fixed at equal intervals on the hot end of the semiconductor cooling chip 13. 14. When the semiconductor cooling chip 13 is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple second fins 15 to drop rapidly, thus cooling the coolant. At the same time, the water pump 7, in conjunction with the outlet pipe 8 and the inlet pipe 9, pumps the coolant into the cavity between the outer casing 1 and the inner casing 20. When the cavity is full of coolant, the excess coolant flows back to the water tank 2 through the two return pipes 10 and the two one-way valves 11 for recooling, so that the used coolant is always kept at a low temperature. This can always maintain a low temperature environment inside the inner casing 20 and improve the heat dissipation effect.

[0022] Furthermore, the blower mechanism includes a blower 6, which is fixed to the top of the outer casing 1, and the air outlet of the blower 6 is connected to the connecting box 5. The filter mechanism includes multiple filter layers 21, which are all fixed on the inner side wall of the connecting box 5 and are located between the blower 6 and the air inlet pipe 16. The blower 6 drives the outside air into the connecting box 5, filters out dust and other impurities in the air through the multiple filter layers 21, and then enters the serpentine tube 17 through the air inlet pipe 16. Since the serpentine tube 17 is in the coolant, the surface temperature of the serpentine tube 17 is low. When the air passes through the inside of the serpentine tube 17, the air temperature is cooled down. The cooled air eventually enters the U-shaped tube 18 and is blown into the inner casing 20 through multiple round holes 19. This can achieve the effect of reducing the battery temperature, slowing down the battery aging rate, and extending the battery life.

[0023] Furthermore, the inner box 20 is equipped with two symmetrical inner side walls with U-shaped plates 3, and one end of each U-shaped plate 3 extends through the outer side wall of the outer box 1. Dustproof nets 4 are fixed to the inner side walls of the two U-shaped plates 3. The heat generated by the battery during operation can be discharged to the outside of the outer box 1 through the two U-shaped plates 3, while the two dustproof nets 4 can prevent external dust from entering the interior of the inner box 20.

[0024] Working Principle: During use, the water tank 2 is pre-filled with coolant. When cooling, the power switch of the semiconductor cooling chip 13 is first turned on. When the semiconductor cooling chip 13 is energized, its cold end temperature drops rapidly, causing the surface temperature of the multiple second fins 15 to drop rapidly, thus cooling the coolant. Simultaneously, the power switch of the water pump 7 is turned on, driving the pump to pump coolant into the cavity between the outer tank 1 and the inner tank 20, in conjunction with the outlet pipe 8 and the inlet pipe 9. When the cavity is full of coolant, excess coolant flows back into the water tank 2 through two return pipes 10 and two one-way valves 11 for re-cooling, ensuring the coolant remains at a low temperature after use. This maintains a consistently low-temperature environment inside the inner tank 20, improving heat dissipation. While the battery is heating up, the power switch of the ventilator 6 is turned on, driving the fan 6 to draw outside air into the connecting box 5. After passing through multiple filter layers 21 to filter out dust and other impurities in the air, the air enters the serpentine tube 17 through the air inlet pipe 16. Since the serpentine tube 17 is in the coolant, the surface temperature of the serpentine tube 17 is low. When the air passes through the inside of the serpentine tube 17, the air temperature is cooled down. The cooled air eventually enters the loop tube 18 and is blown into the inner box 20 through multiple round holes 19. The cooled air blown into the inner box 20 is finally discharged to the outside of the outer box 1 through two loop plates 3. This can carry away the heat generated by the battery during operation to the outside of the outer box 1, thereby reducing the battery temperature, slowing down the battery aging rate, and extending the battery's lifespan.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
