Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new energy battery technology, and more specifically, it relates to a heat dissipation mechanism for thermal management of new energy batteries. Background Technology
[0002] With increasing environmental awareness, new energy vehicles have seen a continuous increase in market share due to their environmentally friendly and energy-saving characteristics. As a core component of new energy vehicles, the performance and lifespan of batteries are highly susceptible to temperature fluctuations. During charging and discharging, batteries generate a significant amount of heat, thus requiring a thermal management and heat dissipation mechanism for new energy batteries. Currently, thermal management and heat dissipation mechanisms for new energy batteries mainly employ technologies such as air cooling, liquid cooling, and direct cooling. Among these, air cooling is widely used due to its ease of maintenance and low cost. This system primarily consists of a fan, air ducts, and heat sinks. The fan generates forced airflow, accelerating air movement to remove heat; the air ducts guide airflow towards the battery pack, ensuring uniform heat dissipation; and heat sinks are installed on or around the battery surface to increase the heat dissipation area and improve heat dissipation efficiency.
[0003] Existing application number
[0004] Based on the above, existing thermal management systems for new energy batteries, when using air cooling, primarily rely on fans to draw in external air, allowing it to flow into the battery structure for heat dissipation, and then expelling the hot air. To prevent excessive impurities from entering the battery system and affecting its normal operation, air filters are typically installed at the air inlet to filter the drawn-in air. However, in areas with high winds and sandstorms, the lifespan of these air filters is significantly shortened. Dust and sand easily clog the filters, causing a decrease in their filtration performance. Furthermore, when the battery is in a state where heat dissipation is not required, the air outlet of the air cooling system can cause dust and impurities to flow back into the battery structure due to factors such as internal and external pressure differences, posing a potential risk to the stable operation of the battery. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a thermal management and heat dissipation mechanism for new energy batteries. This addresses the shortcomings of existing thermal management and heat dissipation mechanisms for new energy batteries, which primarily rely on fans to draw in external air during air-cooling, allowing the air to flow into the battery structure for heat dissipation before expelling the hot air. To prevent excessive impurities from entering the battery system and affecting its normal operation, air filters are typically installed at the air inlet to filter the drawn air. However, in areas with high winds and sandstorms, the lifespan of these air filters is significantly shortened. Dust and sand easily clog the filters, reducing their filtration performance. Furthermore, when the battery is in a state where heat dissipation is not required, the air outlet of the air-cooling mechanism can cause dust and impurities to flow back into the battery structure due to internal and external pressure differences, potentially posing a wind problem to the stable operation of the battery.
[0006] The purpose and effect of this utility model's new energy battery thermal management and heat dissipation mechanism are achieved by the following specific technical means:
[0007] A thermal management and heat dissipation mechanism for a new energy battery includes a battery mounting compartment, an air inlet, an exhaust outlet, an air filter, a dust collection chamber, a fan, an air intake assembly, and an exhaust assembly. The air inlet is located on the right side of the battery mounting compartment; the exhaust outlet is located on the left side of the battery mounting compartment; the air filter is snapped into the air inlet; the dust collection chamber is snapped into the bottom of the air inlet; the fan is bolted into the air inlet; the air intake assembly is located inside the air inlet; and the exhaust assembly is located inside the exhaust outlet.
[0008] Furthermore, the air intake assembly includes an output shaft, a drive shaft, and a timing belt mechanism. The output shaft is coaxially mounted inside the air-cooled fan. The drive shaft is rotatably connected to one side of the air intake. The timing belt mechanism is located at one end of the output shaft and at one end of the drive shaft.
[0009] Furthermore, the air intake assembly also includes: a first electric push rod and a snap-fit plug, wherein the first electric push rod is fixedly installed inside the drive shaft; the snap-fit plug is slidably connected to one end of the drive shaft, and the bottom end of the snap-fit plug is fixedly installed on the top of the first electric push rod.
[0010] Furthermore, the intake assembly also includes: a driven shaft, a snap-fit groove, and a first bevel gear. The driven shaft is rotatably connected to one side of the intake port; the snap-fit groove is formed at one end of the driven shaft; and the first bevel gear is fixedly installed at one end of the driven shaft.
[0011] Furthermore, the air intake assembly also includes: a reciprocating screw, a second bevel gear, a dust removal brush, and an inclined guide plate. The reciprocating screw is rotatably connected inside the air intake. The second bevel gear is coaxially fixedly installed at one end of the reciprocating screw, and the second bevel gear and the first bevel gear mesh with each other. The dust removal brush is horizontally slidably connected inside the air intake and is located in front of the air filter. At least two sets of inclined guide plates are provided, and multiple sets of inclined guide plates are staggered and inclinedly installed inside the dust collection chamber.
[0012] Furthermore, the exhaust assembly includes a guide groove and a protective baffle, wherein the guide groove is fixedly connected to the back of the exhaust port; and the protective baffle is slidably connected inside the guide groove.
[0013] Furthermore, the exhaust assembly also includes a second electric push rod, which is fixedly installed inside the exhaust port, and the top end of the second electric push rod is fixedly installed on one side of the protective baffle.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] Firstly, this utility model has an air intake component. The operation of the air-cooled fan drives a series of components to work together. When the air intake volume decreases, the dust removal brush is automatically driven to clean the air filter. Impurities fall into the dust collection chamber through the inclined guide plate, which effectively solves the problem of easy clogging of the filter and extends its service life.
[0016] Secondly, this invention features an exhaust assembly. When the battery does not require heat dissipation, the second electric push rod drives the protective baffle to slide within the guide groove, sealing the exhaust port and preventing dust and impurities from flowing back due to internal and external pressure differences. When the battery needs heat dissipation, the second electric push rod reverses its operation, causing the protective baffle to move away from the exhaust port, ensuring that hot air is smoothly discharged. This design effectively prevents impurities from entering the battery structure when not dissipating heat, reducing potential risks to battery operation.
[0017] This utility model has the advantages of reducing clogging, convenient maintenance, and coordinated operation. It effectively solves the problem of easy clogging of air filters in windy and sandy areas, ensures the stable operation of the heat dissipation mechanism in harsh environments, and avoids secondary pollution of the battery system by impurities through exhaust protection design, thereby improving the safety and service life of the battery and reducing maintenance costs.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0028] Example 1:
[0029] As attached Figure 1 To be continued Figure 7 As shown:
[0030] This utility model provides a heat dissipation mechanism for thermal management of a new energy battery, including a battery mounting compartment 1, an air inlet 2, an exhaust outlet 3, an air filter 4, a dust collection chamber 5, a fan 6, and an air intake assembly. The air inlet 2 is located on the right side of the battery mounting compartment 1; the exhaust outlet 3 is located on the left side of the battery mounting compartment 1; the air filter 4 is snapped into the air inlet 2; the dust collection chamber 5 is snapped into the bottom of the air inlet 2; the fan 6 is bolted into the air inlet 2; and the air intake assembly is located inside the air inlet 2.
[0031] The intake assembly includes an output shaft 601, a drive shaft 201, and a timing belt mechanism 7. The output shaft 601 is coaxially mounted inside the air-cooled fan 6. The drive shaft 201 is rotatably connected to one side of the air intake port 2. The timing belt mechanism 7 is located at one end of the output shaft 601 and at one end of the drive shaft 201.
[0032] The air intake assembly also includes: a first electric push rod 2011 and a snap-fit plug 2012. The first electric push rod 2011 is fixedly installed inside the drive shaft 201; the snap-fit plug 2012 is slidably connected to one end of the drive shaft 201, and the bottom end of the snap-fit plug 2012 is fixedly installed on the top of the first electric push rod 2011.
[0033] The intake assembly also includes a driven shaft 202, a snap-fit groove 2021, and a first bevel gear 2022. The driven shaft 202 is rotatably connected to one side of the intake port 2. The snap-fit groove 2021 is opened at one end of the driven shaft 202. The first bevel gear 2022 is fixedly installed at one end of the driven shaft 202.
[0034] The air intake assembly also includes: a reciprocating screw 203, a second bevel gear 2031, a dust removal brush 204, and an inclined guide plate 501. The reciprocating screw 203 is rotatably connected inside the air intake 2. The second bevel gear 2031 is coaxially fixedly installed at one end of the reciprocating screw 203, and the second bevel gear 2031 and the first bevel gear 2022 mesh with each other. The dust removal brush 204 is horizontally slidably connected inside the air intake 2 and is located in front of the air filter 4. At least two sets of inclined guide plates 501 are provided, and multiple sets of inclined guide plates 501 are staggered and inclinedly installed inside the dust collection chamber 5.
[0035] The specific usage and function of this embodiment are as follows:
[0036] When the battery pack in battery mounting compartment 1 is in operation and the temperature continuously rises and reaches the preset heat dissipation threshold, the system immediately starts the air cooling process. The air cooling fan 6 starts running, and with its strong suction, it draws outside air into battery mounting compartment 1 from air inlet 2, while the air filter 4 filters and intercepts impurities from the air passing through air inlet 2.
[0037] At the same time, the rotation of the air-cooled fan 6 drives the output shaft 601 to rotate synchronously at high speed. The output shaft 601 is closely connected to the drive shaft 201 through the synchronous belt mechanism 7. With the transmission characteristics of the synchronous belt mechanism 7, the torque is accurately transmitted, driving the drive shaft 201 to rotate smoothly.
[0038] An air flow meter installed at air inlet 2 monitors the airflow in real time. If the airflow drops to a preset threshold, it indicates that the air filter 4 may be clogged due to impurities. At this point, the first electric actuator 2011 responds quickly and immediately begins operation. The first electric actuator 2011 pushes the snap-fit plug 2012, causing it to move precisely along a preset track and smoothly insert into the snap-fit groove 2021 at the end of the driven shaft 202. Thus, the drive shaft 201 and the driven shaft 202 successfully and reliably engage, allowing the rotation of the drive shaft 201 to synchronously drive the driven shaft 202.
[0039] The rotation of the driven shaft 202 causes the first bevel gear 2022 fixed on it to start rotating. The first bevel gear 2022 meshes with the second bevel gear 2031, and through the meshing transmission between the gears, it drives the second bevel gear 2031 to rotate synchronously. The second bevel gear 2031 is coaxially connected to the reciprocating screw 203, and its rotation directly drives the reciprocating screw 203 to rotate.
[0040] As the reciprocating screw 203 continues to rotate, utilizing the transmission principle of the screw thread, the dust removal brush 204 mounted on the screw begins to slide back and forth in front of the air filter 4. The dust removal brush 204 sweeps away the impurities adsorbed on the surface of the air filter 4 one by one, allowing them to fall smoothly into the dust collection chamber 5. The dust collection chamber 5 is equipped with inclined guide plates 501. These guide plates are inclined and arranged alternately, which not only effectively guide the falling impurities but also minimize the risk of the airflow stirring up the impurities already collected in the dust collection chamber 5, achieving stable collection and centralized storage of impurities.
[0041] Example 2:
[0042] Based on Example 1, such as Figures 1 to 7 As shown, it also includes: an exhaust assembly, which is disposed inside the exhaust port 3.
[0043] The exhaust assembly includes a guide groove 301 and a protective baffle 302. The guide groove 301 is fixedly connected to the back of the exhaust port 3, and the protective baffle 302 is slidably connected inside the guide groove 301.
[0044] The exhaust assembly also includes a second electric push rod 303, which is fixedly installed inside the exhaust port 3, and the top of the second electric push rod 303 is fixedly installed on one side of the protective baffle 302.
[0045] The specific usage and function of this embodiment are as follows:
[0046] The second electric push rod 303 drives the protective baffle 302 to slide inside the guide groove 301. The guide groove 301 plays a guiding role when the protective baffle 302 moves. When the battery installation compartment 1 does not need heat dissipation, the protective baffle 302 blocks the heat dissipation holes opened inside the exhaust port 3 to reduce dust, sand and other impurities from entering the battery installation compartment 1 through the exhaust port 3.
[0047] When the new energy battery inside the battery installation compartment 1 is working and reaches the heat dissipation threshold, requiring heat dissipation, the second electric push rod 303 is energized and works. The second electric push rod 303 drives the protective baffle 302 to slide inside the guide groove 301. The protective baffle 302 moves away from the heat dissipation hole inside the exhaust port 3, facilitating the discharge of hot air from inside the battery installation compartment 1.
