Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery technology, specifically relating to a cylindrical battery clamp that prevents overflow. Background Technology
[0002] A cylindrical battery is a type of battery with a cylindrical shape, and its classification is mainly based on the battery's material system and casing type. According to the material system, cylindrical batteries can be divided into different systems such as lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt-manganese hybrid, and ternary materials. According to the casing type, cylindrical batteries can be divided into steel-cased and polymer-cased batteries. Currently, steel-cased cylindrical lithium iron phosphate batteries are the most prevalent in the market.
[0003] Existing cylindrical battery clamps have design flaws that make it difficult to ensure stability during encapsulation. Specifically, the clamp structure may not be able to fully adapt to the shape and size of the battery, making it easy for dead zones to appear during encapsulation. These dead zones not only affect the uniform distribution of the encapsulation but may also lead to poor encapsulation results, thus affecting the overall performance and safety of the battery. Due to problems such as dead zones and uneven encapsulation, the battery may experience heat accumulation after encapsulation. Heat accumulation will cause the internal temperature of the battery to rise, thereby affecting the battery's efficiency and lifespan, especially under high-power discharge or long-term use, where the heat accumulation problem may be more serious. In addition, heat accumulation may also trigger thermal runaway reactions inside the battery, leading to serious consequences such as battery damage or even explosion. The heat dissipation performance of the encapsulation is one of the key factors affecting the battery's heat dissipation effect. However, existing encapsulation methods and clamp designs may not be able to dissipate heat quickly. On the one hand, dead zones and uneven encapsulation may lead to uneven thickness and distribution of the encapsulation, thus affecting the heat dissipation effect. On the other hand, the clamp itself may lack effective heat dissipation channels or structures, making it difficult for the battery to dissipate heat effectively after encapsulation.

[0023] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:
[0024] A spill-proof cylindrical battery clamp, comprising,
[0025] Constraint box 1;

The fixture heat dissipation assembly includes a side plate 2, a circulation pipe 3, a clamping plate 4, a constraint hole 5, a heat dissipation groove 201, a positioning post 202, a receiving groove 203, and a heat-conducting block 204. The positioning post 202 is fixedly installed on the outer wall of the side plate 2. The receiving groove 203 is opened on one side of the outer wall of the side plate 2. The heat-conducting block 204 is fixedly installed on the inner wall of the receiving groove 203. The heat dissipation groove 201 is opened on one side of the outer wall of the side plate 2. The clamping plate 4 is slidably embedded on both sides of the inner wall of the constraint frame 1. The constraint hole 5 is opened on the outer wall of the clamping plate 4. The circulation pipe 3 is embedded in the inner wall of the constraint frame 1.
[0027] In a specific embodiment of this utility model, the clamp heat dissipation component can achieve stable constraint and positioning of the battery body 6. After subsequent injection of thermal grease, it can ensure that the grease stably fills the gaps, avoiding the reduction of its thermal conductivity due to gaps, which would eventually lead to heat accumulation. Furthermore, the introduction of grease can avoid the use of high-viscosity potting compound, greatly reducing potting time and improving production efficiency. First, clean both ends of the outer wall of the battery body 6. Then, place the battery body 6 on the inner wall of the constraint hole 5 of the clamp 4. Next, embed the clamp 4 into the inner wall of the constraint frame 1 to complete the series and parallel connection of the battery body 6. Insulate the wire part. Then, connect the side plate 2 to both sides of the outer wall of the constraint frame 1 through the positioning post 202. Insert the pipe of the silicone grease supply device into the inner wall of the injection hole 101. The silicone grease enters the sealed space formed by the clamp 4 and the constraint frame 1 through the injection groove 401. Excess silicone grease enters the receiving groove 203 to avoid excessive silicone grease injection, which would cause the clamp 4 and the constraint frame 1 to expand. Continuous cooling is achieved by the circulation pipe 3.
[0028] Specifically, the inner wall of the constraint hole 5 is embedded with the battery body 6.
[0029] In a specific embodiment of this utility model, the constraint hole 5 can ensure stable storage and constraint of the battery body 6.
[0030] Specifically, the two ends of the battery body 6 are matched with the heat-conducting block 204.
[0031] In a specific embodiment of this utility model, the two ends of the battery body 6 are matched with the heat-conducting block 204 to ensure heat conduction efficiency.
[0032] Specifically, the outer wall of the clamping plate 4 is provided with an injection groove 401.
[0033] In a specific embodiment of this utility model, the injection groove 401 can achieve stable silicone grease flow.
[0034] Specifically, the outer wall of the constraint frame 1 is provided with an injection hole 101 and a delivery hole 102.
[0035] In a specific embodiment of this utility model, the outer wall of the constraint frame 1 is provided with an injection hole 101 and a delivery hole 102, which can ensure the convenience of installation.
[0036] Specifically, the injection hole 101 is matched with the injection tank 401, the delivery hole 102 is matched with the circulation pipe 3, and the circulation pipe 3 is connected to the external cooling water supply device through a hose.
[0037] In a specific embodiment of this utility model, the circulation pipe 3 is connected to an external cooling water supply device via a flexible hose, which can ensure a stable supply of cooling water.
[0038] Working principle:
[0039] The clamping heat dissipation assembly enables stable constraint and positioning of the battery body 6. After subsequent injection of thermal grease, it ensures that the grease stably fills the gaps, preventing reduced thermal conductivity and heat accumulation due to voids. Furthermore, the introduction of grease avoids the use of high-viscosity potting compound, significantly reducing potting time and improving production efficiency. First, the outer ends of the battery body 6 are cleaned. Then, the battery body 6 is placed on the inner wall of the constraint hole 5 of the clamping plate 4. The clamping plate 4 is then embedded into the inner wall of the constraint frame 1 to complete the series-parallel connection of the battery body 6. The wires are insulated. Next, the side plate 2 is connected to both sides of the outer wall of the constraint frame 1 via positioning posts 202. The grease supply device pipe is inserted into the inner wall of the injection hole 101. The grease enters the sealed space formed by the clamping plate 4 and the constraint frame 1 through the injection groove 401. Excess grease enters the receiving groove 203 to prevent over-injection, which could cause the clamping plate 4 and constraint frame 1 to expand. Continuous cooling is achieved using the circulation pipe 3.
