Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery heat dissipation, in particular to a uniform cooling structure of an air-cooled module. BACKGROUND

[0002] During the charging and discharging process of a battery, heat is generated, and the higher the energy density of the battery, the greater the heat generated. With the popularization of new energy, people have higher and higher requirements for fast charging. When the battery is subjected to large-rate charging and discharging, the temperature rise will rapidly increase. Therefore, a cooling structure is usually arranged in the battery box to discharge the heat generated by the battery out of the box. At present, common cooling methods include fan cooling and liquid cooling. The fan cooling is achieved by installing an exhaust fan in the box body to accelerate the heat exchange of the battery box. However, such a cooling method has a large temperature difference in the temperature reduction of the battery cells arranged in the box body, leading to the problems of reduced battery rate performance and cycle life. The liquid cooling is usually achieved by arranging liquid pipes around the battery and then injecting condensed liquid into the liquid pipes to cool the battery. However, such a cooling method has the problems of occupying the space of the battery module, increasing the weight of the module and reducing the energy density of the module. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above technical problems, the application provides a uniform cooling structure of an air-cooled module, which comprises a box body, a plurality of battery groups arranged in the box body, a gas guide pipe arranged between adjacent two battery groups in the box body and used for releasing cold air, a refrigeration assembly connected to one end of the gas guide pipe, and a plurality of cold air outlets formed in the length direction of the outer wall of the gas guide pipe and corresponding to each battery in the battery group. The application realizes the simplification of the cooling module, the increase of the energy density of the battery module and the avoidance of a large temperature difference in the temperature reduction of the battery module.

[0004] Preferably, a through hole is further formed in one side of the box body, one end of the gas guide pipe is connected to the through hole, and the gas guide pipe is connected to the refrigeration assembly through the through hole, so that the gas guide pipe is connected to the refrigeration assembly in cooperation to cool the battery group.

[0005] Preferably, a gas guide funnel is arranged at one end of the gas guide pipe close to the through hole, and the gas guide pipe is connected to the refrigeration assembly through the gas guide funnel, so that the air intake of the gas guide pipe is increased and the heat dissipation effect of the gas guide pipe is improved.

[0006] Preferably, a gas guide block is detachably embedded at the through hole, and the gas guide block is connected to the gas guide funnel, so that the gas guide pipe is detachably connected to the box body in cooperation, thereby facilitating the long-term use and maintenance of the equipment.

[0007] Preferably, a plurality of fixing columns are arranged in the box along the length direction of the air duct, and the air duct is fixed in the box by the fixing columns to limit and fix the air duct.

[0008] As can be seen from the above, the application has the following beneficial effects: the application sets a plurality of battery groups in the box, sets an air duct for releasing cold air between two adjacent battery groups in the box, connects a refrigeration assembly to one end of the air duct, sets a plurality of cold air outlets on the air duct along the length direction of the air duct and towards the outer wall of the battery group, and the positions of the cold air outlets correspond to the batteries in the battery group. By setting the air duct between two adjacent battery groups in the box and connecting the refrigeration assembly to one end of the air duct, the battery group can be cooled by the simplified air duct cooling module, the space occupied by the battery module is increased, the cold air in the air duct can uniformly cool the battery group by setting the cold air outlets on the air duct and corresponding to the batteries in the battery group, thereby avoiding large temperature difference of the battery group during cooling, simplifying the cooling module, increasing the energy density of the battery module, and avoiding large temperature difference of the battery module during cooling.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0015] Example

[0016] To address the aforementioned technical problems, this embodiment provides a uniform cooling structure for an air-cooled module, such as... Figure 1 As shown, the device includes a housing 10, within which several battery packs 20 are arranged. A vent pipe 12 for releasing cold air is positioned between adjacent battery packs 20 within the housing 10. One end of the vent pipe 12 is connected to a cooling component. Several cold air vents 122 are formed along the length of the vent pipe 12 facing the outer wall of the battery packs 20. The positions of the cold air vents 122 correspond to the individual batteries within the battery packs 20. By using the vent pipe 12 positioned between adjacent battery packs 20 within the housing 10, and with one end connected to the cooling component, the device effectively releases cold air. The air duct 12 occupies little space, which allows for simplified cooling of the battery pack 20 inside the housing 10 by simplifying the air duct 12. This indirectly increases the space available for the battery module. Furthermore, by providing cold air inlets 122 in the air duct 12, with the positions of the cold air inlets 122 corresponding to the individual batteries in the battery pack 20, the cold air in the air duct 12 can dissipate heat evenly to the battery pack 20. This avoids excessive temperature differences between different parts of the battery pack 20 during the cooling process, thus simplifying the cooling module setup, increasing the energy density of the battery module, and preventing large temperature differences during battery module cooling.

[0017] Specifically, such as Figure 2 As shown, a through hole 11 is also provided on one side of the housing 10. One end of the air duct 12 is connected to the through hole 11. The air duct 12 is connected to the cooling component through the through hole 11. By providing a through hole 11 on one side of the housing 10, the air duct 12 is connected to the cooling component through the through hole 11. The air duct 12 can collect cold air through the external cooling component to cool the battery pack 20. The air duct 12 is connected to the cooling component, and the air duct 12 blows cold air out of the cold air port 122 to cool the battery, so as to achieve uniform cooling of the battery pack 20.

[0018] In the above scheme, a gas funnel 121 is provided at one end of the gas duct 12 near the through hole 11. The gas duct 12 is connected to the refrigeration component through the gas funnel 121. By providing the gas funnel 121 at the end of the gas duct 12 near the through hole 11, the refrigeration component can inject cold air into the gas duct 12 through the gas funnel 121, thereby increasing the air intake of the gas duct 12 and improving the heat dissipation effect of the gas duct 12.

[0019] Further, the air guide block 123 is detachably embedded at the through hole 11, and the air guide block 123 is connected with the air guide funnel 121. By detachably arranging the air guide block 123 at the through hole 11, the air guide block 123 is connected with the air guide funnel 121 arranged at one end of the air guide pipe 12, so that the air guide pipe 12 can be detachably arranged in the cabinet 10 through the air guide block 123, and the air guide pipe 12 is detachably connected with the cabinet 10, which is convenient for long-term use and maintenance of the equipment.

[0020] In order to limit and fix the installation position of the air guide pipe 12, as a preferred embodiment, a plurality of fixing columns 13 are arranged in the cabinet 10 along the length direction of the air guide pipe 12. The air guide pipe 12 is fixedly arranged in the cabinet 10 through the fixing columns 13. By arranging the fixing columns 13 in the cabinet 10 along the length direction of the air guide pipe 12, the air guide pipe 12 can be limited and fixed between two adjacent battery packs through the fixing columns 13, and then the positions of the cold air outlets 122 on the outer wall of the air guide pipe 12 can correspond to the positions of the batteries in the battery pack 20, so as to limit and fix the air guide pipe 12.

[0021] In summary, in one or more embodiments of the present application, a plurality of battery packs are arranged in the cabinet, an air guide pipe for releasing cold air is arranged between two adjacent battery packs in the cabinet, a refrigeration assembly is connected with one end of the air guide pipe, a plurality of cold air outlets are arranged on the outer wall of the air guide pipe along the length direction of the air guide pipe, and the positions of the cold air outlets correspond to the positions of the batteries in the battery pack. By arranging the air guide pipe between two adjacent battery packs in the cabinet, and connecting the refrigeration assembly with one end of the air guide pipe, the battery pack can be cooled and heat-dissipated by simplifying the arrangement of the air guide pipe cooling module, so as to indirectly increase the space that can be occupied by the battery module. By arranging the cold air outlets on the air guide pipe, and making the positions of the cold air outlets correspond to the positions of the batteries in the battery pack, the cold air in the air guide pipe can uniformly cool and heat-dissipate the battery pack, so as to avoid that the temperature difference of each part of the battery pack is too large during the cooling process, to simplify the arrangement of the cooling module, to increase the energy density of the battery module, and to avoid that the temperature difference of the battery module is too large during the cooling process.

[0022] The above-described embodiments do not constitute a limitation on the protection scope of the technical solutions. Any modification, equivalent replacement and improvement made within the spirit and principles of the above-described embodiments shall be included in the protection scope of the technical solutions.
