Description

Technical Field

[0001] This utility model belongs to the field of battery accessories technology, specifically a battery storage and heat dissipation device. Background Technology

[0002] With the development of renewable energy and the popularization of electric vehicles, the application of batteries in various fields is increasing, especially lithium-ion batteries, which have become mainstream due to their high energy density and long service life. However, batteries generate heat during charging and discharging, and if this heat cannot be effectively dissipated, it may lead to safety hazards, performance degradation, and energy loss. Therefore, various battery storage and heat dissipation devices have emerged, including passive heat dissipation systems (such as heat sinks) and active heat dissipation systems (such as fans and liquid cooling), as well as the use of phase change materials (PCMs) to balance temperature fluctuations. Design considerations include ambient temperature, battery type, heat dissipation efficiency, and cost. In the future, with technological advancements, heat dissipation devices will become more intelligent, feature innovative materials, and be environmentally friendly, driving the development of the battery industry. Therefore, developing efficient, safe, and economical heat dissipation solutions will be an important challenge for enterprises and research institutions.

[0003] A search revealed an existing patent (publication number: CN213071244U) that discloses a waterproof heat dissipation structure for a storage battery. The structure includes a waterproof cover with an arc-shaped top and an open bottom, a mounting base supporting the bottom of the battery, and a heat dissipation device for cooling the battery. The battery is placed on an inverted T-shaped mounting base fixed to the front of the mounting base. The waterproof cover protects the battery and is connected to the mounting base. Below the mounting base is an inverted U-shaped water collection basin for water storage and heat dissipation. The water collection basin contains the heat dissipation device for cooling the battery. This waterproof heat dissipation structure, through the cooperation of the waterproof cover and the mounting base, stores the battery internally, preventing water intrusion. The heat dissipation device utilizes a rotating cooling fan and water stored in the water collection basin. The rotation of the cooling fan accelerates airflow, causing the water to evaporate and absorb heat, further enhancing the heat dissipation effect.

[0004] However, in actual use, the above-mentioned solutions lack active heat dissipation. This lack of function may lead to a continuous rise in battery temperature, reducing charging efficiency and discharge capacity, shortening battery life, and even causing safety hazards such as thermal runaway, fire, or explosion. Furthermore, increased internal resistance leads to energy loss, reduces system efficiency, limits battery application in high-temperature environments, and increases maintenance and replacement costs.

[0005] Therefore, this utility model provides a battery storage and heat dissipation device. Utility Model Content

The same sealing components are provided inside the first connecting cylinder and the second connecting cylinder.

[0010] Furthermore, the sealing assembly includes a fixing ring, a fixing ring is fixedly connected to the middle of the inner side of the first connecting cylinder, a uniformly distributed slide rod is slidably connected to the inner side of the fixing ring, a pressing block is fixedly connected to the slide rod away from the fixing ring, a limiting post is fixedly connected to the fixing ring near the pressing block, a spring is provided on the outer side of the limiting post near the fixing ring, the spring is fixedly connected to the pressing block at the end away from the fixing ring, a sealing ring is fixedly connected to the inner side of the outer side of the first connecting cylinder, and the same sealing ring is fixedly connected to the inner side of the outer side of the second connecting cylinder.

[0011] Furthermore, the storage component includes a frame, with uniformly distributed frames slidably connected to the inner side of the storage rack, omnidirectional wheels fixedly connected to the bottom end of the frame, uniformly distributed cooling plates fixedly connected to the inner side of the frame, and a first connecting pipe fixedly connected to the cooling plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The battery storage and heat dissipation device of this utility model provides a method for cooling the battery by having coolant enter the heat dissipation box through an inlet pipe and flow through the heat dissipation cavity to the bottom front of the heat dissipation box. During this process, the coolant passes through both sides of the ventilation holes and transfers heat to the inner wall of the ventilation holes, exchanging heat with the outside air to cool the coolant. At the same time, the exhaust fan discharges the air carrying heat, thus continuously cooling the coolant. A delivery pump draws coolant from the inside of the heat dissipation cavity through a second connecting pipe and delivers it through an outlet pipe into the second connecting cylinder on the left side. The coolant is then transported back to the first connecting pipe through the second connecting cylinder, the first connecting cylinder, and the first connecting pipe, and cools the battery placed inside the vehicle frame through the first connecting pipe. This achieves an active cooling function, effectively controlling the battery temperature, preventing overheating, improving charging efficiency and discharge capacity, extending battery life, and reducing maintenance costs. This system reduces the risk of thermal runaway and improves safety, which is especially important in electric vehicles and energy storage systems.

[0015] 2. The battery storage and heat dissipation device of this utility model adopts a modular design by using a sealing assembly to separate the storage component, heat dissipation box, and surrounding components. This allows the storage rack and heat dissipation box to be separated from the storage component, and the storage component can be moved freely by casters, thereby increasing the usage scenarios of the device and allowing for adjustments and optimizations according to different storage environments and heat dissipation requirements. At the same time, the modular design simplifies the maintenance process, allowing users to inspect and repair individual parts, reducing costs and time. Attached Figure Description

[0033] The storage assembly includes a frame 2. The frame 2 is slidably connected to the inner side of the storage rack 1 and is evenly distributed.

[0035] Working principle: When the battery storage and heat dissipation device is in operation, the battery is first placed between the cooling plates 22. Then, using the handle 64 and the casters 21, the frame 2 and the battery are moved into the storage rack 1. Next, the pin 63 is moved to the left and inserted into the locking bracket 62 to fix the frame 2. Then, the first connecting cylinders 3 on the left and right sides are inserted into the second connecting cylinders 31 on the left and right sides and rotated. The first connecting cylinders 3 and the second connecting cylinders 31 are connected by threads. During the process, the pressing blocks 35 are pressed against each other, causing the pressing blocks 35 to move outwards at the same time and compressing the spring 37. This disconnects the pressing blocks 35 from the sealing ring 32 and connects the first connecting cylinders 3 and the second connecting cylinders 31. Then, the delivery pump 26 uses the second connecting pipe 27 to supply heat to the inside of the heat dissipation cavity 42. Coolant is extracted and transported through outlet pipe 25 into the second connecting cylinder 31 on the left, and then transported through the first connecting cylinder 3 and the first connecting pipe 24 into the first connecting pipe 23.

After that, it is transported back into the heat sink 4 and flows from the top side of the rear end of the heat sink 4 to the bottom side of the front end of the heat sink 4. During this process, the air inside the ventilation hole 41 exchanges heat with the coolant transferred to the inner wall of the ventilation hole 41. Then, the air is discharged to the outside by the exhaust fan 51, so that the air inside the ventilation hole 41 is always at a low temperature.
