Description

Technical Field

[0001] This utility model relates to the field of energy storage battery management technology, specifically to a temperature control device for energy storage battery management. Background Technology

[0002] Energy storage battery systems typically consist of multiple battery modules connected in series, with each battery module consisting of one or more individual battery cells connected in parallel. The operating state of energy storage batteries is greatly affected by temperature, therefore, temperature control management is required.

[0003] CN221994564U discloses a temperature control device for energy storage battery management, comprising: a cabinet body, inside which a unit battery module body is disposed; two venting components, each disposed on one side of the inner wall of the cabinet body, each venting component including multiple mounting pipes, the surfaces of the mounting pipes having multiple vent holes sequentially formed from top to bottom, and the mounting pipes being connected by a connecting pipe; and a driving device disposed on the back of the cabinet body. This utility model provides a temperature control device for energy storage battery management. By using venting components on the left and right sides of the inner wall of the cabinet body in conjunction with the driving device, it can deliver external gas to the space between the unit battery modules after prolonged operation and the generation of heat, thereby removing heat between the unit battery modules.

[0004] The aforementioned patent addresses the shortcomings of existing technologies where fans, when blowing air over a large area of ​​the battery module, only contact the surface of the battery module and cannot quickly remove heat between adjacent battery modules. However, the technical solution in this patent only dissipates heat from the battery module through air cooling, relying mainly on airflow to remove heat, which has relatively low heat dissipation efficiency. When the surface temperature of the battery module is too high, it is easy to cause poor heat dissipation due to untimely heat dissipation. Therefore, a temperature control device for energy storage battery management is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a temperature control device for energy storage battery management, which has the advantage of good heat dissipation. It solves the problem that existing temperature control devices use air cooling to dissipate heat from the unit battery module, which mainly relies on airflow to remove heat. Its heat dissipation efficiency is relatively low, and when the surface temperature of the unit battery module is too high, it is easy to cause poor heat dissipation due to untimely heat dissipation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temperature control device for energy storage battery management, comprising an energy storage battery housing, wherein a heat conduction and heat dissipation mechanism is provided on the energy storage battery housing;

[0007] The heat conduction and heat dissipation mechanism includes a cooling fan fixedly installed on one side of the energy storage battery housing and connected to the inside of the energy storage battery housing. A hollow heat conduction partition is fixedly installed inside the energy storage battery housing. A heat conduction plate is fixedly installed inside the hollow heat conduction partition. Heat dissipation fins are fixedly installed on the surface of the heat conduction plate. A first groove is formed on the opposite side surface of the hollow heat conduction partition.

[0008] Furthermore, a protective mesh cover is fixedly installed on the surface of the cooling fan, and an air filter pad is fixedly installed inside the protective mesh cover. The protective mesh cover and the air filter pad are located on the air intake side of the cooling fan.

[0009] Furthermore, an air outlet mesh plate is fixedly installed on the surface of the energy storage battery casing away from the cooling fan, and a protective mesh plate is fixedly installed on the inner side of the air outlet mesh plate.

[0010] Furthermore, there are multiple hollow thermally conductive partitions, and the spacing and height between two adjacent hollow thermally conductive partitions are adapted to the height and thickness of the unit energy storage battery.

[0011] Furthermore, there are multiple heat-conducting plates, which are evenly distributed inside the hollow heat-conducting partition. There are also multiple heat-dissipating fins, which are evenly distributed on the upper and lower surfaces of the heat-conducting plates.

[0012] Furthermore, there are multiple first grooves, which are evenly distributed on the opposite side surface of the hollow heat-conducting partition.

[0013] Furthermore, spacers are fixedly installed on both the left and right surfaces inside the energy storage battery casing, and a second groove is formed on the surface of the spacers.

[0014] Furthermore, air guide grooves are provided on both the upper and lower surfaces inside the energy storage battery casing, and the number of air guide grooves is multiple and evenly distributed on the upper and lower surfaces inside the energy storage battery casing.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This temperature control device for energy storage battery management improves airflow within the battery casing through a cooling fan, a first groove, a second groove, and an air guide duct, thereby removing some heat. The combination of a hollow thermally conductive partition, a thermally conductive plate, and heat dissipation fins enhances heat conduction and dissipation. The thermally conductive plate can quickly conduct the heat generated by the unit battery module to the heat dissipation fins, while the heat dissipation fins further improve heat dissipation efficiency by increasing the heat dissipation area. This not only accelerates the heat transfer speed but also makes the heat dissipation more uniform, avoiding localized overheating. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5A temperature control device for energy storage battery management in this embodiment includes an energy storage battery housing 1. The energy storage battery housing 1 is provided with a heat conduction and heat dissipation mechanism. The heat conduction and heat dissipation mechanism includes a cooling fan 2 fixedly installed on one side of the energy storage battery housing 1 and connected to the inside of the energy storage battery housing 1. A hollow heat conduction partition 3 is fixedly installed inside the energy storage battery housing 1. A heat conduction plate 4 is fixedly installed inside the hollow heat conduction partition 3. Heat dissipation fins 5 are fixedly installed on the surface of the heat conduction plate 4. A first groove 6 is opened on the opposite side surface of the hollow heat conduction partition 3.

[0025] It should be noted that a protective mesh cover 7 is fixedly installed on the surface of the cooling fan 2, and an air filter pad 8 is fixedly installed inside the protective mesh cover 7. The protective mesh cover 7 and the air filter pad 8 are located on the air intake side of the cooling fan 2. By setting the protective mesh cover 7 and the air filter pad 8, it is convenient to filter the air entering the energy storage battery housing 1, which can prevent the cooling fan 2 from bringing dust into the energy storage battery housing 1 and affecting the heat dissipation of the energy storage battery. An exhaust mesh plate 9 is fixedly installed on the side of the energy storage battery housing 1 away from the cooling fan 2, and a protective mesh plate 10 is fixedly installed on the inner side of the exhaust mesh plate 9. By setting the exhaust mesh plate 9, it is convenient for the cooling fan 2 to send the heat inside the energy storage battery housing 1 out of the energy storage battery housing 1. At the same time, the protective mesh plate 10 can prevent debris from entering the energy storage battery housing 1 through the exhaust mesh plate 9.

[0026] The device includes multiple heat-conducting plates 4, which are evenly distributed inside the hollow heat-conducting partition 3. It also includes multiple heat dissipation fins 5, which are evenly distributed on the upper and lower surfaces of the heat-conducting plates 4. Furthermore, it includes multiple first grooves 6, which are evenly distributed on the opposite side surface of the hollow heat-conducting partition 3. By setting the first grooves 6, a heat dissipation channel can be formed between the unit energy storage battery and the hollow heat-conducting partition 3, which is beneficial to improving the air circulation on the surface of the unit energy storage battery.

[0027] It should be noted that there are multiple hollow thermally conductive partitions 3. The spacing and height between two adjacent hollow thermally conductive partitions 3 are adapted to the height and thickness of the unit energy storage battery, which facilitates the installation of the unit energy storage battery between two adjacent hollow thermally conductive partitions 3.

[0028] It should be noted that spacers 11 are fixedly installed on the left and right surfaces inside the energy storage battery housing 1. The surface of the spacers 11 has a second groove 12. By setting the spacers 11, the unit energy storage battery can be prevented from directly contacting the inner surface of the energy storage battery housing 1. At the same time, the spacers 11 and the second groove 12 can form multiple heat dissipation channels between the unit energy storage battery and the left and right surfaces inside the energy storage battery housing 1. Air guide slots 13 are provided on the upper and lower surfaces inside the energy storage battery housing 1. There are multiple air guide slots 13, which are evenly distributed on the upper and lower surfaces inside the energy storage battery housing 1. By setting the air guide slots 13, the air flow inside the energy storage battery housing 1 can be improved, thereby improving the heat dissipation efficiency inside the energy storage battery housing 1.

[0029] The working principle of the above embodiments is as follows:

[0030] When the energy storage battery generates heat during operation, this heat is conducted to the hollow heat-conducting separator 3 and the heat-conducting plate 4. The heat dissipation area can be increased by the heat dissipation fins 5. The cooling fan 2 draws external cold air into the energy storage battery housing 1. When the cold air flows through the heat dissipation fins 5, it will carry away the heat on the heat dissipation fins 5. The first groove 6, the spacer 11, the second groove 12 on the surface of the spacer 11, and the air guide 13 inside the energy storage battery housing 1 provide additional channels for air flow, making the hot air more smoothly discharged from the energy storage battery housing 1, thereby improving the heat dissipation efficiency.
