Battery pack temperature control and heat dissipation circulating pipeline

Abstract

This utility model relates to a battery pack temperature control and heat dissipation circulation pipeline, comprising: a side frame, a cover plate mounted on the side frame, a base plate mounted below the side frame, and a partition plate installed inside the side frame to divide the side frame into an installation area and a heat dissipation area. An installation plate is mounted in the installation area, and a battery module is mounted on the installation plate. A circulation component, a heat conduction component, and a heat dissipation component are provided inside the installation area and the heat dissipation area. By setting the partition plate, the complete space formed by the side frame, cover plate, and base plate is divided into two parts: one part for installing the battery module and the other part for installing the heat dissipation component. The circulation component circulates and pushes the heat exchange medium to achieve heat dissipation for the battery module. Simultaneously, the heat absorbed by the heat exchange medium is transferred to the heat dissipation area, where a cooling fan cools the heat exchange medium, thereby cooling the pipeline. This prevents the heat generated by the battery module from damaging the pipeline.

Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, specifically relating to a battery pack temperature control and heat dissipation circulation pipeline. Background Technology

[0002] In the temperature management system of the battery pack, the temperature control and heat dissipation circulation pipeline is the core fluid transport carrier for achieving precise control of battery temperature. It connects to the heat exchange area inside the battery pack at one end and to the external heat exchange module at the other end through the internal circulating "heat exchange medium" (such as coolant, refrigerant, etc.), forming a closed heat exchange loop. Ultimately, it achieves precise control of battery temperature through active heat exchange.

[0003] However, the circulation pipeline and the battery modules inside the battery pack share the same enclosed space. During the rapid charging process of the battery modules, they release a large amount of heat due to intense electrochemical reactions. If this heat accumulates over a long period of time, it will not only cause local overheating, but also have a continuous impact on the adjacent circulation pipeline—for example, accelerating the aging of pipeline materials, increasing the risk of pipeline interface sealing failure, and even causing a decrease in the stability of the pipeline structure due to temperature fluctuations, thereby affecting the reliability of the entire temperature control system. To address these issues, we propose a battery pack temperature control and heat dissipation circulation pipeline. Utility Model Content

[0004] The purpose of this invention is to provide a battery pack temperature control and heat dissipation circulation pipeline to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A battery pack temperature control and heat dissipation circulation pipeline includes: Side frame; A cover plate, the cover plate being installed on the upper side of the side frame; A base plate, which is installed on the underside of the side frame; A partition, which is installed inside the side frame, is used to divide the side frame into an installation area and a heat dissipation area; Mounting plate, the mounting plate is mounted on the lower side of the mounting area; Several battery modules, each of which is mounted on the mounting plate; Both the installation area and the heat dissipation area are equipped with a circulating heat dissipation component. The circulating heat dissipation component includes: Circulation components are used to circulate and transport the heat exchange medium. Thermal conductive components are used to absorb and conduct heat generated by each of the battery modules; Heat dissipation components are used to cool the heat exchange medium.

[0006] Further specifying, the loop component includes: A coolant pump, wherein the coolant pump is installed on the lower side of the inner wall of the heat dissipation area; An output pipe, one end of which is connected to the output port of the coolant pump; An upper heat-conducting plate is installed on the upper side of the installation area. The upper heat-conducting plate has a first cavity inside and is connected to the other end of the output pipe. A connecting pipe is provided between the mounting plates, which have a second cavity inside. The connecting pipe is used to connect the first cavity and the second cavity. The input pipe has several support rods fixed on the lower side of the inner wall of the heat dissipation area. The input pipe is placed on the upper side of each of the support rods. One end of the input pipe is connected to the second cavity, and the other end is connected to the input port of the coolant pump.

[0007] Further specifying, the thermally conductive component includes: The lower heat-conducting plate is disposed inside the second cavity and is in close contact with the upper wall of the second cavity; A plurality of heat-absorbing plates are provided, each heat-absorbing plate being disposed between adjacent battery modules, and one end of each heat-absorbing plate passing through the mounting plate being fixedly connected to the lower heat-conducting plate; A plurality of heat sinks are provided, each of which is fixedly connected to the lower side of the lower heat-conducting plate and abuts tightly against the lower wall of the second cavity.

[0008] Further specifying, the heat dissipation component includes: A cooling fan is installed on the inner wall of the heat dissipation area, and the air outlet of the cooling fan faces the input pipe. A heat-conducting ring is provided, wherein the input pipe is arranged in a serpentine shape, and the heat-conducting ring wraps around and fits the outside of the input pipe; Heat dissipation fins are fixed to the end of the heat-conducting ring facing the cooling fan.

[0009] Further, both the cover plate and the bottom plate are provided with through slots, which correspond to the heat dissipation area. The upper through slot is provided with a grid strip, and the lower through slot is provided with several guide vanes at an incline.

[0010] The beneficial effects of this utility model are: 1. By setting a partition inside the side frame, the space is divided into an independent installation area and a heat dissipation area, which realizes the physical isolation between the battery module (heat generating component) and the pipeline and heat dissipation component (components susceptible to high temperature). Compared with the existing structure where "heat generating and heat dissipation components are in the same space", it can reduce the direct radiation / conduction of battery heat to the pipeline from the source and reduce the impact on pipeline materials.

[0011] 2. By configuring a multi-dimensional heat-conducting component in the installation area, consisting of an upper heat-conducting plate, a heat-absorbing plate, a lower heat-conducting plate, and a heat sink, the heat-absorbing plate directly adheres to the battery module to absorb contact heat, the upper heat-conducting plate absorbs radiant heat from the upper part of the battery, and the lower heat-conducting plate and heat sink assist in heat conduction. Compared with the existing single heat-conducting structure, this can more comprehensively capture heat from all directions of the battery module, avoid local heat accumulation, and at the same time increase the heat exchange area through the heat sink to improve the efficiency of heat transfer to the medium.

[0012] 3. By designing a closed-loop assembly consisting of a coolant pump, output pipe, upper heat conduction plate, connecting pipe, mounting plate, and input pipe, the heat exchange medium circulates along a fixed path. Compared with existing non-closed or fragmented circulation structures, this ensures that the medium continuously absorbs heat in the installation area and cools down in the heat dissipation area, achieving directional heat transfer and preventing high-temperature medium from lingering in the installation area and affecting the battery and pipelines.

[0013] 4. By setting the input pipe to a serpentine shape and matching it with a heat-conducting ring and heat dissipation fins, the serpentine structure extends the residence time of the medium in the heat dissipation zone, the heat-conducting ring quickly dissipates the heat of the medium inside the pipe, and the heat dissipation fins increase the heat dissipation area. Compared with the existing straight pipe structure without auxiliary heat dissipation, the medium cooling efficiency is greatly improved, ensuring that the medium flowing back to the installation area is always at a low temperature and improving temperature control stability.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1-6 As shown, a battery pack temperature control and heat dissipation circulation pipeline includes: Side frame 100; Cover plate 101 is installed on the upper side of side frame 100; Base plate 102 is installed on the underside of side frame 100; Partition 103 is installed inside the side frame 100 to divide the side frame 100 into an installation area 104 and a heat dissipation area 105. Mounting plate 106 is installed on the lower side of mounting area 104; Several battery modules 107 are mounted on a mounting plate 106. The installation area 104 and the heat dissipation area 105 are both equipped with a circulating heat dissipation component; The circulating heat dissipation component includes: Circulation components are used to circulate and transport the heat exchange medium. Thermal conductive components are used to absorb and conduct heat generated by each battery module 107; Heat dissipation components are used to cool the heat exchange medium.

[0019] The side frame 100 serves as the basic support structure for the entire battery pack's temperature control and heat dissipation circulation pipeline, providing an installation carrier for components such as the cover plate 101, bottom plate 102, and separator 103, ensuring the stability and integrity of the overall structure.

[0020] The cover plate 101 is installed on the upper side of the side frame 100 to protect the interior of the side frame 100 and prevent the internal components from being damaged by external impact.

[0021] The base plate 102 is installed on the underside of the side frame 100, and together with the cover plate 101, it forms a complete protective space to ensure the stability of the overall structure.

[0022] The side frame 100, cover plate 101, and bottom plate 102 together form a complete external structure of the battery pack.

[0023] The partition 103 is installed inside the side frame 100, dividing the internal space of the side frame 100 into an independent installation area 104 and a heat dissipation area 105, thereby achieving physical isolation between the battery module 107 and heat dissipation-related components.

[0024] Mounting plate 106 is installed inside the lower side of mounting area 104 to provide a mounting platform for several battery modules 107, ensuring the accuracy and stability of the mounting position of battery modules 107, and also conducting heat generated by battery modules to a certain extent. The mounting plate 106 has a discharge port on its lower side, which can discharge heat exchange medium that has been used for a long time, so as to replace the heat exchange medium.

[0025] Battery module 107, as the core energy storage and output component of the battery pack, provides power to external devices.

[0026] The circulation component provides power and channels for the flow of heat exchange medium inside the side frame 100, realizing the circulation and transportation of heat exchange medium. This allows the heat exchange medium to absorb heat inside the installation area 104 and then be transported to the heat dissipation area 105 for cooling, before returning to the installation area 104 for reuse.

[0027] The heat-conducting component absorbs the heat generated by the battery module 107 and conducts the heat to the circulating heat exchange medium, realizing the transfer of heat from the battery module 107 to the heat exchange medium, laying the foundation for the subsequent removal of heat by the heat exchange medium.

[0028] The heat dissipation component cools the heat exchange medium that flows through the heat dissipation zone 105 after absorbing heat in the installation zone 104, thereby reducing the temperature of the heat exchange medium so that it can be returned to the installation zone 104 to absorb heat, thus realizing the recycling of the heat exchange medium and continuous heat dissipation.

[0029] The loop component includes: Coolant pump 200 is installed on the lower side of the inner wall of heat dissipation area 105; Output pipe 201, one end of which is connected to the output port of coolant pump 200; The upper heat-conducting plate 202 is installed on the upper side of the installation area 104. The upper heat-conducting plate 202 has a first cavity 203 inside and is connected to the other end of the output pipe 201. The connecting pipe 204 has a second cavity 205 inside the mounting plate 106. The connecting pipe 204 is located between the mounting plate 106 and the mounting plate 106 and is used to connect the first cavity 203 and the second cavity 205. The input pipe 206 has several support rods 207 fixed on the lower side of the inner wall of the heat dissipation area 105. The input pipe 206 is placed on the upper side of each support rod 207. One end of the input pipe 206 is connected to the second cavity 205, and the other end is connected to the input port of the coolant pump 200.

[0030] The coolant pump 200 provides the power source for the circulation of the heat exchange medium, driving the heat exchange medium to flow continuously in the circulation channel.

[0031] The output pipe 201 connects the output port of the coolant pump 200 and the upper heat-conducting plate 202, and delivers the heat exchange medium output by the coolant pump 200 to the upper heat-conducting plate 202, providing a flow channel for the heat exchange medium from the coolant pump 200 to the upper heat-conducting plate 202.

[0032] The upper heat-conducting plate 202 has a first cavity 203 inside, which is used to store and transport the heat exchange medium. At the same time, it can absorb the heat in the upper part of the installation area 104 and transfer it to the heat exchange medium inside, thereby cooling the upper part of the installation area 104. The upper heat-conducting plate 202 is provided with a feed port, which can inject the heat exchange medium into the first cavity 203 to achieve medium filling.

[0033] The connecting pipe 204 is disposed between the mounting plate 106 and the upper heat-conducting plate 202, and is used to connect the first cavity 203 of the upper heat-conducting plate 202 and the second cavity 205 of the mounting plate 106, providing a channel for the heat exchange medium to flow from the first cavity 203 to the second cavity 205.

[0034] The inlet pipe 206 is connected at one end to the second cavity 205 of the mounting plate 106 and at the other end to the inlet of the coolant pump 200. It transports the heat exchange medium that has absorbed heat in the second cavity 205 back to the coolant pump 200, and at the same time receives cooling treatment from the heat dissipation components in the heat dissipation area.

[0035] The support rod 207 is fixed to the lower side of the inner wall of the heat dissipation zone 105 to support the input pipe 206, ensuring that the installation position of the input pipe 206 inside the heat dissipation zone 105 is stable, and preventing the input pipe 206 from shifting or being damaged due to its own weight or the flow of the heat exchange medium.

[0036] Thermal conductive components include: The lower heat-conducting plate 300 is disposed inside the second cavity 205 and is in close contact with the upper wall of the second cavity 205. Several heat-absorbing plates 301 are provided, each heat-absorbing plate 301 is disposed between adjacent battery modules 107, and each heat-absorbing plate 301 is fixedly connected to the lower heat-conducting plate 300 through one end of the mounting plate 106. Several heat sinks 302 are fixedly connected to the lower side of the lower heat conduction plate 300 and tightly abut against the lower wall of the second cavity 205.

[0037] The lower heat-conducting plate 300 is disposed inside the second cavity 205 and closely abuts against the upper wall of the second cavity 205. It receives the heat transferred by the heat-absorbing plate 301 and transfers the heat to the heat exchange medium in the second cavity 205. At the same time, it can also assist in the uniform distribution of heat through its own thermal conductivity.

[0038] The heat absorption plate 301 is disposed between adjacent battery modules 107. One end passes through the mounting plate 106 and is fixedly connected to the lower heat conduction plate 300, directly contacting the battery module 107 to absorb the heat generated by the battery module 107 during operation. For example, the installed battery modules 107 are divided into two rows and several columns. In this way, one heat absorption plate 301 is located between the two rows, separating the battery modules 107 in the two rows. The other heat absorption plates 301 are located between each column. This allows each battery module 107 to be in a relatively independent space, thereby preventing heat accumulation in each battery module 107 and thus affecting the normal charging of the battery module 107.

[0039] The heat sink 302 is fixedly connected to the lower side of the lower heat conduction plate 300, increasing the heat dissipation area of ​​the lower heat conduction plate 300. When the heat exchange medium flows through the interior of the second cavity 205, it can accelerate the heat dissipation speed of the lower heat conduction plate 300, help reduce the temperature of the lower heat conduction plate 300, and thus improve the efficiency of the heat absorption plate 301 in absorbing the heat of the battery module 107. The heat sink 302 is in close contact with the lower wall of the second cavity 205, which can make the lower heat conduction plate 300 in close contact with the inner wall of the second cavity 205, thereby preventing the heat exchange medium from flowing out from the gap between the heat absorption plate 301 and the mounting plate 106.

[0040] The heat dissipation components include: Cooling fan 400 is installed on the inner wall of the heat dissipation area 105, and the air outlet of cooling fan 400 faces the input pipe 206. The heat-conducting ring 401 and the input pipe 206 are arranged in a serpentine shape, with the heat-conducting ring 401 wrapped around and attached to the outside of the input pipe 206. Heat dissipation fins 402 are fixed to the end of the heat conduction ring 401 facing the cooling fan 400.

[0041] The cooling fan 400 is installed on the inner wall of the heat dissipation area 105, with its air outlet facing the input pipe 206. After starting, it generates airflow that blows towards the input pipe 206, accelerating the flow of air around the input pipe 206 and carrying away the heat on the outside of the input pipe 206, thereby cooling the heat exchange medium inside the input pipe 206.

[0042] The heat-conducting ring 401 wraps around and fits the outside of the input pipe 206, quickly transferring the heat of the heat exchange medium inside the input pipe 206 to its own surface, providing conditions for the heat dissipation of the subsequent heat dissipation fins 402 and cooling fan 400. The input pipe 206 is located inside the heat dissipation zone 105 and is arranged in a serpentine bend. This allows the heat exchange medium to stay inside the heat dissipation zone 105 for a longer period of time, thus providing more time to cool down the input pipe 206. After cooling down, the heat exchange medium can more efficiently remove the heat generated by the battery module 107.

[0043] The heat dissipation fins 402 are fixed to the end of the heat conduction ring 401 facing the cooling fan 400, increasing the heat dissipation area of ​​the heat conduction ring 401, improving the heat dissipation efficiency, and working with the airflow of the cooling fan 400 to accelerate the heat dissipation speed on the heat conduction ring 401.

[0044] Both the cover plate 101 and the bottom plate 102 have through slots, which correspond to the heat dissipation area 105. The upper through slot has a grid strip inside, and the lower through slot has several guide vanes 403 arranged at an angle.

[0045] The grille bars allow the cooling fan 400 to draw air in through the gaps between the grille bars and discharge it to the inlet pipe 206. This ensures that the air blown by the cooling fan 400 flows smoothly and prevents heat from accumulating.

[0046] The air guide vane 403 is inclined and guides the air entering the heat dissipation area 105 from the lower through slot, so that the air can be blown into the heat guide ring and improve the heat dissipation effect on the heat exchange medium. One part of the air guide vanes 403 are set to tilt forward and downward, and the other part is set to tilt backward and downward. The bottom plate 102 is provided with a groove on the side of the air guide vanes 403 that are tilted forward and downward, so that the air guide vanes 403 can protrude. The outside air can be guided into the heat dissipation area 105 through the air guide vanes 403. The air blown out by the cooling fan 400 will be discharged from the air guide vanes 403 on the other side. This can further improve the cooling treatment of the outside of the input pipe 206.

[0047] Initially: The first cavity 203 and the second cavity 205 are filled with heat exchange medium; When the battery module is charged rapidly, the electrochemical reaction intensifies, releasing a large amount of heat. The temperature in the installation area continues to rise, and the heat diffuses towards the piping side: S1. Physical isolation, blocking direct heat dissipation: The partition 103 separates the installation area 104 and the heat dissipation area 105 into independent spaces. The installation area 104 is used to install components that generate heat, such as the battery module 107, while the heat dissipation area 105 is used to install pipes, heat dissipation components, etc., thereby preventing the heat released by the battery module 107 from being directly radiated or conducted to the pipes, initially reducing the heat baking of the pipe materials and slowing down the aging rate of the pipes. The side frame 100, cover plate 101 and bottom plate 102 work together to form a closed structure to avoid interference from the external environment.

[0048] S2. Absorbs heat, reducing heat buildup: After the battery module 107 generates heat, the heat absorption plate 301 between adjacent modules directly contacts the surface of the battery module 107 and quickly absorbs heat. The heat absorbed by the heat absorption plate 301 will be conducted to the lower heat conduction plate 300. Combined with the upper heat conduction plate 202 absorbing the radiant heat on the upper side of each battery module 107, the heat in all directions of the battery module 107 can be absorbed. When the heat exchange medium flows through the first cavity 203 and the second cavity 205, it can carry away the heat on the upper heat conduction plate 202 and the lower heat conduction plate 300. The heat absorption plate 301 separates each battery module 107 into an independent section, which can prevent heat from accumulating. Among them, the heat sink 302 increases the heat dissipation area, and when the heat exchange medium flows through each heat sink 302, it can help reduce the temperature of the lower heat conduction plate 300. The entire heat absorption assembly can fully control the temperature of the installation area 104 and reduce the diffusion of heat to the internal piping side of the heat dissipation area 105.

[0049] S3. Medium circulation transfers heat to the heat dissipation area: Start the coolant pump 200, and its output port delivers the low-temperature heat exchange medium to the first cavity 203 of the upper heat conduction plate 202 through the output pipe 201. After the medium absorbs the heat conducted by the upper heat conduction plate 202 in the first cavity 203, it flows into the second cavity 205 of the mounting plate 106 through the connecting pipe 204. The medium comes into contact with the lower heat-conducting plate 300 and the heat sink 302 in the second cavity 205, further absorbing the heat transferred by the battery module 107, and the temperature rises. Subsequently, the high-temperature medium flows to the heat dissipation area 105 through the input pipe 206, realizing the "transfer of heat from the installation area 104 to the heat dissipation area 105", thus preventing the installation area 104 from being in a high-temperature environment for a long time and affecting the normal use of the battery module 107. The upper heat-conducting plate 202 absorbs the radiant heat emitted by the battery module 107, while the lower heat-conducting plate 300 absorbs the contact heat. In this way, when the heat exchange medium absorbs the heat on the upper heat-conducting plate 202, it will not affect the heat of the lower heat-conducting plate 300.

[0050] S4. Cool down to ensure media recycling: The input tube 206 is arranged in a serpentine shape in the heat dissipation area 105 to extend the residence time of the medium in the heat dissipation area 105 and provide sufficient time for cooling. Meanwhile, a heat-conducting ring 401 is wrapped around the outside of the inlet pipe 206. The heat-conducting ring 401 quickly conducts the heat of the medium inside the pipe to the heat dissipation fins 402. The heat dissipation fins 402 increase the heat dissipation area and improve the heat release efficiency.

[0051] When the cooling fan 400 is turned on, its exhaust port faces the input pipe 206, generating a directional airflow that blows towards the heat dissipation fins 402 and the input pipe 206, accelerating heat dissipation. At this time, the cooling fan 400 guides external cold air into the heat dissipation area 105 through the gap between the grille bars, and the inclined air guide vanes 403 in the through slot of the base plate 102 direct the airflow to the outside, thereby forming an airflow circulation of "upward air intake and downward air exhaust", which quickly removes heat and reduces the medium temperature to the preset range. Some of the air guide vanes 403 are set with different tilt directions, and the two different tilt directions form an "eight" shape. This allows some air to enter the heat dissipation area 105 and be discharged from the other air guide vanes 403.

[0052] The cooled medium flows back to the inlet of the coolant pump 200 through the inlet pipe 206 and re-enters the circulation, preventing the high-temperature medium from absorbing heat again after flowing back to the installation area 104, which would cause the pipeline to be immersed in the high-temperature medium for a long time, thus ensuring the stability of the pipeline structure.

[0053] S5. Continuous circulation to maintain stable temperature control system: As the battery module 107 continues to charge, the above-mentioned "heat absorption-circulation-cooling" steps continue, and the temperature of the installation area 104 is always controlled within a safe range to avoid thermal runaway of the battery module 107 due to local high temperature. At the same time, the pipeline is always in the relatively low temperature heat dissipation area 105 environment and is in contact with the cooled medium, which greatly reduces the impact on the pipeline and ensures the continuous and reliable operation of the temperature control system.

[0054] In this embodiment, by setting a partition, the complete space composed of the side frame, cover plate and bottom plate is divided into two parts. One part is used to install the battery module and the other part is used to install the heat dissipation component. Then, the heat exchange medium is circulated and pushed by the circulation component, thereby realizing the heat conduction and heat dissipation of the battery module. At the same time, the heat absorbed by the heat exchange medium is transported to the heat dissipation area. The cooling fan drives the air flow to cool the heat exchange medium, thereby cooling the pipeline. This can prevent the heat generated by the battery module from damaging the pipeline.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
