Description

Technical Field

[0001] This utility model relates to the field of heat conduction device technology, specifically a rapid heat conduction connection device for lithium battery terminals in low-temperature environments. Background Technology

[0002] Lithium-ion battery terminal heat dissipation effectively reduces the temperature gradient along the diameter of cylindrical lithium-ion batteries, thereby reducing internal temperature unevenness and current distribution, and slowing down battery degradation. Through terminal heat dissipation, the cycle life of lithium-ion batteries can be improved, capacity decay caused by temperature unevenness can be reduced, and overall battery performance and lifespan can be enhanced. A well-designed heat dissipation system can also reduce the risks associated with high temperatures, minimizing performance degradation and safety hazards, and improving the safety of lithium-ion battery use. However, traditional lithium battery terminal heat dissipation devices have the following drawbacks: Traditional lithium battery terminal heat conduction devices have an unreliable connection with the lithium battery terminals. The gaps between them affect the cooling and heat conduction efficiency of the lithium battery terminals themselves, thus impacting the subsequent use of the lithium battery. Utility Model Content

[0003] The purpose of this invention is to provide a rapid thermal conductivity connection device for lithium battery terminals in low-temperature environments, in order to solve the problem mentioned in the background art that the connection between the traditional lithium battery terminal thermal conductivity device and the lithium battery terminal is not reliable, and the gap between the two will affect the cooling and thermal conductivity efficiency of the lithium battery terminal itself, thus affecting the subsequent use of the lithium battery.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid thermal conductive connection device for lithium battery terminals in a low-temperature environment, comprising a fixed base, a displacement stage at the top of the fixed base, a thermal conductive housing fixedly mounted on one side of the top of the displacement stage, a cooling component fixedly mounted on the top of one side of the thermal conductive housing, an mounting plate fixedly mounted on one side of the bottom of the inner wall of the thermal conductive housing, a first cooling clamping plate fixedly mounted on one side of the mounting plate, and a connecting component mounted on the other side of the bottom of the inner wall of the thermal conductive housing. The connecting component includes a screw and a push plate, a fixed frame slidably connected to the middle of the screw and the thermal conductive housing, one side of the fixed frame being fixedly connected to one side of the push plate, and a second cooling clamping plate fixedly mounted on the other side of the push plate.

[0005] Preferably, a motor frame is fixedly installed on the side of the displacement stage away from the heat-conducting housing, and a servo motor is fixedly installed on the top of the motor frame. The output end of the servo motor is fixedly connected to the end of the screw directly opposite it. When the servo motor is powered on, it starts and drives the screw to rotate. The thread on the surface of the screw matches the thread on the inner wall of the fixed frame. The fixed frame is limited by the heat-conducting housing, which matches its shape and size. Therefore, the fixed frame slides along the screw to adjust the position of the push plate, so that the first cooling clamp and the second cooling clamp are clamped and connected from both sides of the lithium battery electrode post.

[0006] Preferably, the top ends of the first cooling plate and the second cooling plate are both fixedly connected to a connecting joint. When the first cooling plate and the second cooling plate are energized, when the current passes through the interface of the two different materials, the charge carrier will release heat when moving from the high energy level to the low energy level, and vice versa. The cooling plate conducts heat transfer and cooling from both sides of the lithium battery terminal.

[0007] Preferably, the cooling component includes a cooling rack and a fan. The top of the cooling rack is fixedly connected to the bottom of the fan. The air inlet of the fan is fixedly connected to an air inlet pipe with a filter screen. The air outlet of the fan is fixedly connected to a conveying pipe extending into the interior of the heat-conducting housing. Several cooling plates are fixedly installed on the surface of the conveying pipe. One end of the cooling rack is fixedly connected to the heat-conducting housing. When the fan is powered on, it starts and draws in ambient gas through the air inlet pipe with a filter screen. The drawn gas is cooled by the cooling plates and then conveyed to the interior of the heat-conducting housing through the conveying pipe. When the cooling plates are powered on, when the current passes through the interface between two different materials, the charge carrier releases heat when moving from a high energy level to a low energy level, and absorbs heat when moving from a low energy level to a high energy level.

[0008] Preferably, one side of the heat-conducting housing is fixedly connected to an exhaust pipe located below the cooling component, and a sealing door is hinged to the front of the heat-conducting housing, through which the low-temperature gas inside the heat-conducting housing is discharged to the outside.

[0009] Preferably, limit plates are fixedly installed on both sides of the top of the fixed base, and a lead screw is rotatably connected between the two limit plates. The middle part of the lead screw is threadedly connected to a movable block that is slidably connected to the fixed base. The top of the movable block is fixedly connected to the middle of the bottom of the displacement table. An external motor drives the lead screw to rotate. The thread on the surface of the lead screw matches the thread on the inner wall of the movable block. The movable block is limited by the fixed base, which matches its shape and size. Therefore, the movable block drives the displacement table to move synchronously and adjusts the relative position of the displacement table and the fixed base.

[0010] Preferably, each of the four corners of the bottom of the displacement stage is fixedly equipped with a sliding rod that is slidably connected to the fixed base. The displacement stage slides relative to the fixed base through the sliding rods, thereby improving the stability of the displacement stage during sliding.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the connecting component and the first cooling clamp, the fixing frame slides relative to the screw, and the fixing frame pushes the push plate, so that the first cooling clamp and the second cooling clamp clamp are clamped and fixed from both sides of the battery terminal, the lithium battery terminal directly contacts the cooling, the heat transfer speed is fast, and the service life of the lithium battery terminal is extended.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1-4 This utility model provides a rapid heat conduction connection device for lithium battery terminals in low-temperature environments, including a fixed base 1, a displacement stage 3 at the top of the fixed base 1, a heat conduction housing 5 fixedly installed on one side of the top of the displacement stage 3, a cooling component 7 fixedly installed on the top of one side of the heat conduction housing 5, an installation plate 12 fixedly installed on one side of the bottom of the inner wall of the heat conduction housing 5, a first cooling clamping plate 13 fixedly installed on one side of the installation plate 12, and a connecting component 4 installed on the other side of the bottom of the inner wall of the heat conduction housing 5. The connecting component 4 includes a screw 43 and a push plate 45. A fixing frame 44 that is slidably connected to the middle of the screw 43 is threadedly connected to the heat conduction housing 5. One side of the fixing frame 44 is fixedly connected to one side of the push plate 45, and a second cooling clamping plate 46 is fixedly installed on the other side of the push plate 45.

[0016] A motor frame 41 is fixedly installed on the side of the displacement stage 3 away from the heat-conducting housing 5. A servo motor 42 is fixedly installed on the top of the motor frame 41. The output end of the servo motor 42 is fixedly connected to the end of the screw 43 facing each other. When the servo motor 42 is powered on, it starts and drives the screw 43 to rotate. The thread on the surface of the screw 43 matches the thread on the inner wall of the fixing frame 44. The fixing frame 44 is limited by the heat-conducting housing 5, which matches its shape and size. Therefore, the fixing frame 44 slides along the screw 43 and adjusts the position of the push plate 45 so that the first cooling clamp 13 and the second cooling clamp 46 are clamped and connected from both sides of the lithium battery electrode post.

[0017] The top of the first cooling plate 13 and the top of the second cooling plate 46 are both fixedly connected to a connecting joint 14. When the first cooling plate 13 and the second cooling plate 46 are energized, when the current passes through the interface of the two different materials, the charge carrier will release heat when moving from the high energy level to the low energy level, and vice versa. The cooling plates conduct heat transfer and cooling from both sides of the lithium battery terminal.

[0018] The cooling component 7 includes a cooling rack 71 and a fan 72. The top of the cooling rack 71 is fixedly connected to the bottom of the fan 72. The air inlet of the fan 72 is fixedly connected to an air inlet pipe 73 with a filter screen. The air outlet of the fan 72 is fixedly connected to a conveying pipe 74 extending into the interior of the heat-conducting housing 5. Several cooling chips 75 are fixedly installed on the surface of the conveying pipe 74. One end of the cooling rack 71 is fixedly connected to the heat-conducting housing 5. When the fan 72 is powered on, it starts and draws in ambient gas through the air inlet pipe 73 with a filter screen. The drawn gas is cooled by the cooling chips 75 and then conveyed into the heat-conducting housing 5 through the conveying pipe 74. When the cooling chips 75 are powered on, when the current passes through the interface between two different materials, the charge carrier releases heat when moving from a high energy level to a low energy level, and vice versa.

[0019] The heat transfer housing 5 is fixedly connected to an exhaust pipe 8 located below the cooling component 7 on one side. The front of the heat transfer housing 5 is hinged with a sealing door 6. The low-temperature gas inside the heat transfer housing 5 is discharged to the outside through the exhaust pipe 8.

[0020] Limiting plates 9 are fixedly installed on both sides of the top of the fixed base 1. A lead screw 10 is rotatably connected between the two limiting plates 9. A movable block 11 that is slidably connected to the fixed base 1 is threadedly connected to the middle of the lead screw 10. The top of the movable block 11 is fixedly connected to the middle of the bottom of the displacement table 3. An external motor drives the lead screw 10 to rotate. The thread on the surface of the lead screw 10 matches the thread on the inner wall of the movable block 11. The movable block 11 is limited by the fixed base 1, which matches its shape and size. Therefore, the movable block 11 drives the displacement table 3 to move synchronously and adjust the relative position of the displacement table 3 and the fixed base 1.

[0021] The four corners at the bottom of the displacement stage 3 are all fixedly installed with sliding rods 2 that are slidably connected to the fixed base 1. The displacement stage 3 slides relative to the fixed base 1 through the sliding rods 2, thereby improving the stability of the displacement stage 3 during sliding.

[0022] In this embodiment, during use: an external motor drives the lead screw 10 to rotate, the thread on the surface of the lead screw 10 matches the thread on the inner wall of the movable block 11, and the movable block 11 is limited by the fixed base 1, which matches its shape and size. Therefore, the movable block 11 drives the displacement stage 3 to move synchronously, adjusting the relative position of the displacement stage 3 and the fixed base 1. After the servo motor 42 is powered on, it starts and drives the screw 43 to rotate. The thread on the surface of the screw 43 matches the thread on the inner wall of the fixed frame 44, and the fixed frame 44 is limited by the heat-conducting housing 5, which matches its shape and size. Therefore, the fixed frame 44 slides along the screw 43, adjusting the position of the push plate 45, so that the first cooling plate 13 and the second cooling plate 46 move from both sides of the lithium battery electrode post. The clamping connection is established, and the first cooling clamp 13 and the second cooling clamp 46 are energized. When the current passes through the interface between the two different materials, the charge carriers release heat when moving from a high energy level to a low energy level, and vice versa. The cooling clamps conduct heat transfer and cooling from both sides of the lithium battery terminal. After the fan 72 is energized, it starts and draws in ambient gas through the air intake pipe 73 with a filter. The drawn gas is cooled by the cooling plate 75 and then transported to the heat-conducting housing 5 through the delivery pipe 74. When the cooling plate 75 is energized, the current passes through the interface between the two different materials, and the charge carriers release heat when moving from a high energy level to a low energy level, and vice versa. This conducts heat transfer and cooling on the lithium battery terminal. The low-temperature gas in the heat-conducting housing 5 is discharged to the outside through the exhaust pipe 8.
