Description

Technical Field

[0001] This utility model relates to the field of energy storage control cabinet technology, specifically to a heat dissipation fan module for an energy storage control cabinet. Background Technology

[0002] The energy storage control cabinet monitors the battery status information through the BMS and shares it with the EMS and PCS. The EMS sends the control information to the PCS and BMS based on optimization and scheduling decisions to realize the charging and discharging control of individual batteries or battery packs. The PCS is responsible for converting DC power into AC power to meet the needs of external systems.

[0003] When the energy storage control cabinet is in normal operation, it needs to dissipate heat through the heat dissipation module. Most of the current heat dissipation modules simply open heat dissipation slots on the surface of the cabinet for natural heat exchange, or set two fans in opposite directions to exchange heat with the outside. The former has low heat dissipation efficiency, and the latter is prone to bringing heat back into the cabinet when transferring heat to the outside, affecting the normal use of other modules inside the cabinet. Utility Model Content

[0004] The purpose of this invention is to provide a cooling fan module for an energy storage control cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention features a first fan on one side of the control box that guides heat to the surface of the heat sink fins and a second fan that blows away the heat from the surface of the heat sink fins. This allows the heat inside the control box to be quickly dissipated through the heat sink fins, while the heat on the surface of the heat sink fins can be quickly dissipated through the second fan. This keeps the heat absorption efficiency of the heat sink fins at its highest, thereby accelerating the heat dissipation efficiency of the heat dissipation module.

[0015] 2. This utility model incorporates a connection structure between the heat dissipation fins and the partition, enabling a detachable connection between the heat dissipation fins and the partition.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a cooling fan module for an energy storage control cabinet, including a control box 1. A first housing 2 is fixedly mounted on the surface of the control box 1 with screws. The surface of the first housing 2 is embedded inside the control box 1. A second housing 3 is fixedly mounted on the surface of the first housing 2 with screws. A partition 4 is fixedly mounted between the first housing 2 and the second housing 3 with screws. A through groove 24 is provided on the surface of the partition 4. Multiple heat dissipation fins 5 are installed at equal intervals inside the through groove 24. A notch 6 is provided on the surface of the first housing 2. One side of the multiple heat dissipation fins 5 abuts against the surface of the notch 6 and is connected to the outside. The other side of the multiple heat dissipation fins 5 abuts against the surface of the first housing 2. A first fan 7 is fixedly mounted on the surface of the first housing 2. A second fan 8 is mounted on the surface of the second housing 3. The first fan 7 delivers gas from the control box 1 to the outside, and the second fan 8 blows away the heat from the surface of the heat dissipation fins 5.

[0026] Please see Figure 1 , 2In the process of the first fan 7 delivering gas to the outside, the gas first passes through the heat sink 5 to heat it. Since the heat sink 5 has a large overall surface area, it can absorb most of the heat. The second fan 8 can blow away the heat on the surface of the heat sink 5 to achieve the heat dissipation effect.

[0027] A connection structure is provided between the heat dissipation fins 5 and the through groove 24. The connection structure includes a locking block 9, a connecting seat 10, a cavity 11, a locking groove 12, a recess 13, and a locking plate 14. The cavity 11 is located inside the connecting seat 10, and the locking groove 12 is located on the side of the connecting seat 10. The cavity 11 communicates with the inside of the locking groove 12. The locking block 9 is fixedly installed on the surface of the heat dissipation fins 5. The recess 13 is located on the surface of the locking block 9. The locking plate 14 is slidably installed in the cavity 11, and one end of the locking plate 14 is engaged in the locking groove 12. The surface of the partition plate 4 is provided with a sliding groove 15. A drive seat 16 is slidably installed inside the sliding groove 15. A connecting plate 17 is fixedly installed on the surface of the drive seat 16, and one end of the connecting plate 17 is fixedly connected to the surface of the locking plate 14.

[0028] Please see Figure 5 and 6 After the partition 4 is separated, the drive seat 16 can be moved inside the slide groove 15 by pulling the surface of the partition 4. At this time, the distance between the drive seat 16 and the edge of the partition 4 is reduced. The drive seat 16 can pull the locking plate 14 to move inside the cavity 11 through the connecting plate 17. When the locking plate 14 moves, one end of it can be disengaged from the inside of the groove 13, so that the heat dissipation fins 5 can be removed from the partition 4.

[0029] It should be noted that a single heat sink fin 5 is installed between two connecting seats 10. The two connecting seats 10, together with the through slot 24, can limit its position on the X and Z axes. Finally, with the setting of the groove 13 and the locking plate 14, the heat sink fin 5 can be limited on the Y axis, thereby realizing the connection between the heat sink fin 5 and the partition plate 4.

[0030] The connection structure also includes a receiving groove 23, which is located on the inner wall of the through groove 24. The locking block 9 on the heat dissipation fin 5 closest to the side wall of the through groove 24 is engaged inside the receiving groove 23.

[0031] Please see Figure 5 The structure of the receiving groove 23 is the same as that of the limiting groove 22, and it can accommodate the locking block 9 on the heat dissipation fin 5 closest to the side wall of the through groove 24, which allows multiple heat dissipation fins 5 to be exchanged arbitrarily.

[0032] The two opposite end faces of the locking block 9 are both set as inclined planes 18, and the projection of the locking block 9 on the horizontal plane is an isosceles trapezoid.

[0033] Please see Figure 6 Since the installation of the heat dissipation fins 5 requires them to be moved laterally into the through slot 24, the slope 18 facilitates the heat dissipation fins 5 to enter the gap between the two connecting seats 10, so as to prevent the side of the locking block 9 from colliding with the connecting seat 10 during the lateral movement, which would cause the heat dissipation fins 5 to get stuck when moving.

[0034] An elastic structure is provided between the locking plate 14 and the cavity 11. The elastic structure includes a spring 19 and a slide rod 20. The slide rod 20 is fixedly installed inside the cavity 11. The locking plate 14 is slidably connected to the surface of the slide rod 20. The spring 19 is fixedly installed between the cavity 11 and the locking plate 14 and is sleeved on the surface of the slide rod 20.

[0035] Please see Figure 7 When the drive seat 16 is pulled on the surface of the partition plate 4, the drive seat 16 can drive the locking plate 14 to move inside the cavity 11 through the connecting plate 17. At this time, the locking plate 14 will move synchronously on the surface of the slide bar 20 and compress the spring 19 to store energy. At this time, the locking plate 14 will disengage from the inside of the groove 13 to facilitate the removal of the heat dissipation fins 5. When the cleaned heat dissipation fins 5 are reinstalled, the heat dissipation fins 5 are moved laterally into the through groove 24 and the drive seat 16 is released. At this time, under the action of the spring force of the spring 19, the locking plate 14 resets and re-enters the groove 13 to limit the heat dissipation fins 5. The locking plate 14 can drive the drive seat 16 to reset synchronously through the connecting plate 17.

[0036] The side of the drive seat 16 is integrally formed with a limiting protrusion 21, and a limiting groove 22 is formed between the drive seat 16 and the two limiting protrusions 21. The limiting groove 22 is slidably connected to the slide groove 15.

[0037] Please see Figure 4 and 5 The limiting protrusion 21 and the limiting groove 22 can limit the drive seat 16 so that it can only move inside the slide groove 15, so that the locking plate 14 can be pulled by the connecting plate 17.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
