Description

Technical Field

[0001] This utility model relates to the field of air-cooling technology, specifically to an energy storage air-cooling module. Background Technology

[0002] The energy storage industry is developing rapidly, and energy storage boxes come in two forms: air-cooled and liquid-cooled. Although the application of liquid-cooled energy storage boxes is gradually increasing, air-cooled modules remain the mainstream in some markets due to their ease of installation and maintenance. Existing air-cooled modules add a fan to the front panel of the box, and air inlets are opened on the rear panel and both side panels. Driven by the fan, cool air from the outside enters the box through the rear and side inlets and is then blown out by the front fan. As the cool air passes through the box, it carries away the heat generated by the battery modules, but the uniformity of cooling needs improvement. Utility Model Content

As the cool air passes through the ventilation slots on the upper surface of the support base, it carries away the heat generated by the battery module located above it. The cool air fully contacts the battery module, improving the uniformity of cooling of the air-cooled module. Furthermore, without the obstruction of a casing, the status of the cells in each battery module is easily observed, allowing for precise location of problematic cells and early prevention of safety and fire hazards. Moreover, eliminating the need for a casing reduces material usage, saving costs, and simplifies installation, reducing labor time. Attached Figure Description

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] Example, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As an embodiment of this utility model, an energy storage air-cooled module is proposed for cooling a battery module 19. It includes a support base 1, a positioning plate 2, and a fan 3. The support base 1 supports the battery module 19, and its upper surface has a ventilation groove 4. The battery module 19 is located above the ventilation groove 4. The air inlet end of the support base 1 has an air inlet 5, and the air outlet end of the support base 1 has an air outlet 6. Both the air inlet 5 and the air outlet 6 are connected to the ventilation groove 4. The positioning plate 2 is disposed on the support base 1 and located at the air outlet end of the support base 1. The positioning plate 2 has an air duct 7, and the air outlet 6 is connected to the air duct 7. The fan 3 is disposed on the positioning plate 2, with its inlet end connected to the air duct 7 and its outlet end facing outwards from the positioning plate 2.

[0048] This invention eliminates the need for a casing. The battery module 19 is placed directly on the support base 1, above the ventilation slot 4. Under the action of a fan, cool air from the outside enters the ventilation slot 4 through the air inlet 5 at one end of the support base 1, then through the air outlet 6 at the other end of the support base 1 into the air duct 7 of the positioning plate 2, and finally exits from the outlet of the fan 3. As the cool air passes through the ventilation slot 4 on the upper surface of the support base 1, it carries away the heat generated by the battery module 19 located above it. The cool air's full contact with the battery module 19 improves the uniformity of cooling. Furthermore, without the obstruction of a casing, the status of the cells in each battery module 19 is easily observed, allowing for precise location of problematic cells and early prevention of safety and fire hazards. Moreover, eliminating the need for a casing reduces material usage, saves costs, and facilitates installation, reducing labor time.

[0049] Furthermore, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the support base 1 includes a support beam 1-1, a base plate 1-2, and a support longitudinal beam 1-3. There are at least two support beams 1-1, all arranged along the length of the positioning plate 2. The battery module 19 is placed above the support beams 1-1. The base plate 1-2 is positioned between two adjacent support beams 1-1, with its upper surface below the upper surface of the support beam 1-1. The upper surface of the base plate 1-2 is flush with the upper surface of the two adjacent support beams 1-1. The cavity between the upper surfaces of 1 is the ventilation slot 4; the supporting longitudinal beam 1-3 is located at the end of the supporting transverse beam 1-1, and the same end of all supporting transverse beams 1-1 is set on the same supporting longitudinal beam 1-3. The positioning plate 2 is set on the supporting longitudinal beam 1-3, and the air inlet 5 and air outlet 6 are both located on the supporting longitudinal beam 1-3. The supporting longitudinal beam 1-3 has a central hole structure, and the two ends of the supporting longitudinal beam 1-3 near the positioning plate 2 are closed structures, while at least one end of the other supporting longitudinal beam 1-3 is an open structure. The supporting transverse beam 1-1, the base plate 1-2, and the supporting longitudinal beam 1-3 are spliced ​​together, and the lower surfaces of the three are flush. The thickness of the base plate 1-2 is less than the thickness of the supporting transverse beam 1-1 and the supporting longitudinal beam 1-3, thus forming the ventilation slot 4 above the base plate 1-2, which eliminates the need for grooving.

[0050] Furthermore, such as Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, both ends of the base plate 1-2 have reinforcing parts 1-4, which are located above the base plate 1-2 and inside the supporting longitudinal beam 1-3. The reinforcing parts 1-4 have through holes 1-5 communicating with the interior of the supporting longitudinal beam 1-3. The reinforcing parts 1-4 increase the connection area between the base plate 1-2 and the supporting longitudinal beam 1-3, and between the base plate 1-2 and the supporting crossbeam 1-1, making the connections between the base plate 1-2 and the supporting longitudinal beam 1-3, and between the base plate 1-2 and the supporting crossbeam 1-1, more robust and reliable without affecting heat dissipation.

[0051] Furthermore, such as Figure 7 As shown, a mounting port 8 is provided on the positioning plate 2, and the fan 3 is installed at the mounting port 8. The inlet end of the fan 3 is connected to the air duct 7 through the mounting port 8. The mounting port 8 is provided on the positioning plate 2 to facilitate the installation and removal of the fan 3. The fan 3 is locked to the positioning plate 2 with locking bolts for easy disassembly and maintenance.

[0052] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, an air intake vent 9 is provided at the bottom of the support base 1 at the end away from the positioning plate 2, and the air intake vent 9 is connected to the ventilation slot 4. When the support base 1 is raised, under the action of the fan 3, external cold air can also enter the ventilation slot 4 through the air intake vent 9, which can increase the air intake area.

[0053] Furthermore, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the system also includes an end baffle 10 and side baffles 11. The end baffle 10 is mounted on the support base 1 and located at the end of the support base 1 away from the positioning plate 2. Side baffles 11 are provided at both ends of the end baffle 10, and the side baffles 11 are located on the side of the end baffle 10 facing the positioning plate 2. The end baffle 10 and the two side baffles 11 can all limit the battery module 19, preventing the battery module 19 from slipping off the support base 1, thus improving safety.

[0054] Furthermore, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes handles 12. Handles 12 are provided at both ends of the end baffle 10, and the handles 12 are located on the side of the end baffle 10 away from the positioning plate 2. Two handles 12 are provided on the outer side of the end baffle 10, front and rear, so that it is convenient to push and pull the support base 1 by holding the handles 12.

[0055] Furthermore, such as Figure 11 and Figure 12 As shown, the battery module 19 has a first pull ring 20 at one end near the end baffle 10, and also includes a first positioning crossbar 13 and a first limiting nut 14. The first positioning crossbar 13 is detachably disposed between the two side baffles 11. The first pull ring 20 is used to be fitted onto the first positioning crossbar 13. The first limiting nut 14 is threadedly connected to the first positioning crossbar 13. There are at least two first limiting nuts 14. The first pull ring 20 is clamped between two adjacent first limiting nuts 14. During installation, first pass the first positioning crossbar 13 through the first pull ring 20 on the battery module 19 and clamp the first pull ring 20 between the front and rear first limiting nuts 14. Then, lock the first positioning crossbar 13 between the two side baffles 11. During disassembly, first remove the locking structure between the first positioning crossbar 13 and the two side baffles 11. Then, rotate the first limiting nut 14 or the first positioning crossbar 13 to separate the first limiting nut 14 from the first positioning crossbar 13, and then separate the first positioning crossbar 13 from the first pull ring 20. The structure is simple, the connection is firm and reliable, it can effectively position the battery module 19, and it is convenient and quick to install and disassemble, saving time and effort. Figure 12 As shown, for easier disassembly and assembly, the first positioning crossbar 13 is mostly smooth, with external threads only provided at the part where the first limiting nut 14 needs to be installed. The first limiting nut 14 can slide along the smooth part of the first positioning crossbar 13.

[0056] Furthermore, such as Figure 11 and Figure 12 As shown, it also includes a support plate 15 and fastening nuts 16. The support plate 15 is set on the side baffle 11, and the first positioning crossbar 13 is inserted into the support plate 15. Fastening nuts 16 are threaded to both ends of the first positioning crossbar 13, and the inner end face of the fastening nuts 16 contacts the outer wall of the support plate 15. Support plates 15 are set on both the front and rear side baffles 11, and the front and rear fastening nuts 16 are located on the outside of the support plates 15. By threading the fastening nuts 16 to the first positioning crossbar 13 and making the inner end face of the front and rear fastening nuts 16 contact the outer wall of the corresponding end support plate 15, the first positioning crossbar 13 can be locked between the front and rear support plates 15, thereby locking the first positioning crossbar 13 between the front and rear side baffles 11. The connection is firm and reliable, and the disassembly and assembly are convenient and quick, saving time and effort.

[0057] Furthermore, such as Figure 11 and Figure 12As shown, the battery module 19 has a second pull ring 21 at one end near the positioning plate 2, and also includes a second positioning crossbar 17 and a second limiting nut 18. The second positioning crossbar 17 is detachably mounted on the positioning plate 2, and the second pull ring 21 is used to fit onto the second positioning crossbar 17. The second limiting nut 18 is threadedly connected to the second positioning crossbar 17, and there are at least two second limiting nuts 18. The second pull ring 21 is clamped between two adjacent second limiting nuts 18. During installation, first pass the second positioning crossbar 17 through the second pull ring 21 on the battery module 19 and clamp the second pull ring 21 between the front and rear second limiting nuts 18, and then lock the second positioning crossbar 17 onto the positioning plate 2. During disassembly, first remove the locking structure between the second positioning crossbar 17 and the positioning plate 2, and then rotate the second limiting nut 18 or the second positioning crossbar 17 to separate the second limiting nut 18 from the second positioning crossbar 17, and then separate the second positioning crossbar 17 from the second pull ring 21. With a simple structure and a firm, reliable connection, it effectively positions the battery module 19 and is easy and quick to assemble and disassemble, saving time and effort. Figure 12 As shown, for easier assembly and disassembly, the second positioning crossbar 17 is mostly smooth, with external threads only at the locations where the second limiting nut 18 needs to be installed. The second limiting nut 18 can slide along the smooth portion of the second positioning crossbar 17. To facilitate the assembly and disassembly of the second positioning crossbar 17, two support plates 15 are also provided on the positioning plate 2. Two fastening nuts 16 are threaded onto the second positioning crossbar 17, and the inner end faces of the two fastening nuts 16 contact the outer walls of the corresponding support plates 15, thereby locking the second positioning crossbar 17 between the two support plates 15.
