[0001] This utility model relates to the field of energy storage technology, and in particular to a portable energy storage power supply structure with high-efficiency heat dissipation. Background Technology

[0002] With the development of energy storage technology, portable energy storage power supplies have been widely used. In existing technologies, most portable energy storage devices adopt a sealed plastic shell structure design. Portable energy storage devices carry a large number of energy storage components, and during long-term operation, the temperature of power-generating components such as inverters in portable energy storage power supplies will rise.

[0003] In order to prevent dust and water damage, existing portable energy storage power supplies use a fully enclosed casing, which restricts air circulation and prevents internal heat from being dissipated in time, affecting the stable operation of the portable energy storage power supply and its service life. Summary of the Invention

[0004] The main objective of this invention is to propose a portable energy storage power supply structure with high heat dissipation efficiency, aiming to solve the technical problem of heat dissipation performance of portable energy storage power supplies in the prior art.

[0005] To achieve the above objectives, this utility model proposes a portable energy storage power supply structure with high-efficiency heat dissipation, comprising:

[0006] The mounting housing includes a top cover, a bottom plate, and side plates. The top cover, the bottom plate, and the side plates form a cavity for mounting energy storage components. The side plates include two opposing first side plates and two opposing second side plates. At least two cooling fans are provided in the cavity, and the at least two cooling fans are opposingly arranged on the two second side plates.

[0007] Each of the second side panels has at least one vent that communicates with the receiving cavity, which is located opposite the cooling fan. The vent allows the cooling fan to introduce external cold air into the receiving cavity. A heat dissipation structure is also provided below one of the vents.

[0008] In some embodiments, the heat dissipation structure includes a plurality of heat dissipation holes arranged in an array, the heat dissipation holes being connected to the receiving cavity.

[0009] In some embodiments, each of the ventilation openings is provided with four connecting posts around its perimeter, one end of each connecting post is connected to the second side plate, and the cooling fan is detachably connected to the other end of the connecting post.

[0010] In some embodiments, any of the second side panels is provided with two ventilation openings, which are arranged side by side.

[0011] In some embodiments, four cooling fans are provided, and each of the four cooling fans is connected to one of the ventilation openings.

[0012] In some embodiments, a dust filter is connected to the end of the vent facing away from the receiving cavity.

[0013] In some embodiments, the portable energy storage power supply further includes an inverter assembly connected to the inner wall of the upper cover.

[0014] In some embodiments, the mounting housing is also provided with a handle.

[0015] In some embodiments, one of the first side panels is provided with a plurality of charging ports.

[0016] In some embodiments, the heat dissipation holes are in the shape of regular polygons.

[0017] The mounting housing of this utility model's high-efficiency heat dissipation portable energy storage power supply structure consists of a top cover, side plates, and a bottom plate, forming a receiving cavity.

[0028] Please refer to Figures 1 to 4. This utility model provides a portable energy storage power supply structure with high-efficiency heat dissipation, including a mounting housing 1. The mounting housing 1 includes a top cover 11, a bottom plate 12, and side plates 13. The top cover 11, bottom plate 12, and side plates 13 form a cavity 10 for mounting energy storage components. The side plates 13 include two opposing first side plates 131 and two opposing second side plates 132. At least two cooling fans 2 are provided in the cavity 10, and the at least two cooling fans 2 are oppositely arranged on the two second side plates 132. Each second side plate 132 has at least one ventilation port 1321 that communicates with the cavity 10, which allows the cooling fans 2 to introduce external cold air into the cavity 10. A heat dissipation structure 133 is also provided below one of the ventilation ports 1321.

[0029] The mounting housing 1 is an important part of protecting the internal components of the portable energy storage power supply 100. Its material can be engineering plastic, which has advantages such as high strength and low creep, and can effectively protect the internal energy storage components. Of course, the above is just an example, and the specific choice can be determined according to actual needs. This utility model does not limit it.

[0030] In this embodiment, the first side plate 131 is a relatively long side plate 13, mainly used to set various connection ports for external devices to connect to the portable energy storage power supply 100. The second side plate 132 is a relatively short side plate 13, and the second side plate 132 is provided with at least one ventilation opening 1321, which can guide external cold air into the housing cavity 10. When the portable energy storage power supply 100 is running for a long time, the cold air can dissipate the heat generated by various components in the housing cavity 10, avoid the components being damaged by excessive temperature in the housing cavity 10, and improve the safety, stability and service life of the portable energy storage power supply 100.

[0031] In this embodiment, there are two sets of second side plates 132. Correspondingly, to further improve the heat dissipation performance of the portable energy storage power supply 100, both sets of second side plates 132 are equipped with vents 1321. The two sets of vents 1321 are arranged opposite each other, enabling them to simultaneously perform heat dissipation functions, guiding more cool air into the housing cavity 10 to remove heat and improving the safety and stability of the portable energy storage power supply 100. Simultaneously, each vent 1321 is directly connected to a cooling fan 2. The cooling fan 2 is the power source for airflow, actively guiding external cool air into the housing cavity 10 to enhance heat dissipation. The two oppositely arranged cooling fans 2 can form an effective air convection channel. Cool air enters the housing cavity 10 from one vent 1321, passes through heat-generating components such as the battery cells, and then the hot air is discharged from the other vent 1321, quickly removing the heat generated during the operation of the portable energy storage power supply 100 and preventing overheating from affecting the battery cell performance and lifespan.

[0032] The two ventilation openings 1321 can have the same shape, both being circular; or one can be circular and the other rectangular. Of course, the above are just examples, and the specific design can be determined according to actual needs. This utility model does not impose any limitations here.

[0033] Please refer to Figure 3. In order to further optimize the heat dissipation performance of this utility model, a heat dissipation structure 133 is provided below the vent 1321 on one of the second side plates 132. It works together with the vent 1321 to further improve the heat dissipation effect of the portable energy storage power supply 100.

[0034] In this embodiment, when the portable energy storage power supply 100 is working, the inverter components 5 and others inside the housing cavity 10 continuously dissipate heat. The vent 1321 and heat dissipation structure 133 are located at different positions on the second side plate 132, forming an effective air convection channel in conjunction with the cooling fan 2. Cool air enters the housing cavity 10 from the heat dissipation structure 133 near the bottom plate 12 and the vent 1321 on the same side. After passing through heat-generating components such as the battery cells, the hot air is exhausted from the vent 1321 at the other end. This quickly removes the heat generated during device operation, preventing overheating from affecting battery cell performance and lifespan, and improving the safety and stability of the portable energy storage power supply 100.

[0035] In this embodiment, the cooling fan 2 is positioned below the circuit board within the housing cavity 10. When the portable power storage device 100 is in operation, the circuit board continuously generates heat. The cooling fan 2 introduces cool air through the vent 1321. This cool air passes over the lower end of the circuit board, contacting it and carrying away the heat, thus cooling the circuit board and preventing damage from high temperatures. This improves the safety, stability, and lifespan of the portable power storage device 100.

[0036] Please refer to Figure 2. In some embodiments, the portable energy storage power supply 100 also includes an inverter assembly 5. The inverter assembly 5 is connected to the inner wall of the upper cover 11, which can free up space in the housing cavity 10, which is beneficial for heat dissipation inside the housing cavity 10 and improves the heat dissipation performance of the portable energy storage power supply.

[0037] In some embodiments, the heat dissipation structure 133 includes a plurality of heat dissipation holes 1331 arranged in an array, and the heat dissipation holes 1331 are connected to the receiving cavity 10.

[0038] The array of heat dissipation holes 1331 allows heat to be dissipated evenly, avoiding the problem of localized overheating. This helps extend the lifespan of the internal components of the portable power storage unit 100, preventing premature aging or damage to some components due to uneven temperature distribution. Furthermore, the arrangement of the heat dissipation holes 1331 guides airflow. When the cooling fan 2 introduces cool external air into the housing cavity 10, the air can convect through the heat dissipation holes 1331, accelerating the expulsion of hot air and further improving heat dissipation efficiency.

[0039] Please refer to Figure 3. Specifically, the shape of the heat dissipation hole 1331 is a regular polygon. For example, the shape of the heat dissipation hole 1331 is a regular hexagon. The regular hexagonal design can increase the area of ​​the heat dissipation hole 1331, make full use of the area of ​​the second side plate 132, construct a larger number of heat dissipation holes 1331, improve airflow, and optimize heat dissipation performance. Of course, the above is only an example, and the specific shape design can be determined according to actual needs. This utility model does not impose any limitations here.

[0040] In some embodiments, each vent 1321 is provided with four connecting posts 3 circumferentially, one end of each connecting post 3 is connected to the second side plate 132, and the cooling fan 2 is detachably connected to the other end of the connecting post 3.

[0041] Please refer to Figure 4. To ensure the cooling fan 2 can be stably installed within the housing cavity 10, four connecting posts 3 are connected to the cooling fan 2 on the second side plate 132. Specifically, the four connecting posts 3 are evenly distributed around the circumference of the ventilation opening 1321. Correspondingly, four positioning holes 21 are constructed at the four corners of the cooling fan 2. During installation, align the connecting posts 3 with the positioning holes 21 one by one and then connect them with bolts.

[0042] In some embodiments, any second side panel 132 is provided with two vents 1321, which are arranged side by side.

[0043] This invention can be understood as having four vents 1321 arranged in pairs facing each other. By setting four vents 1321, the primary airflow of cold air can be increased, guiding more cold air into the receiving cavity 10, quickly removing the heat inside the receiving cavity 10, and lowering the temperature to protect the portable energy storage power supply 100.

[0044] In some embodiments, four cooling fans 2 are provided, and the four cooling fans 2 are respectively connected to a ventilation port 1321.

[0045] On the one hand, the four cooling fans 2 utilize the convection of the ventilation vents 1321 to significantly improve the overall heat dissipation efficiency, which can dissipate the heat generated by the portable power storage 100 more quickly and effectively, maintain the housing 10 at a lower temperature level, ensure the stable operation of the portable power storage 100, and avoid performance degradation, crashes and other problems caused by overheating.

[0046] On the other hand, the arrangement of multiple cooling fans 2 increases the redundancy of the heat dissipation function of the portable energy storage power supply 100. Even if one of the cooling fans 2 fails or its performance degrades, the other cooling fans 2 can still continue to work and maintain a certain heat dissipation capacity, reducing the risk of damage to the portable energy storage power supply 100 due to the failure of one of the cooling fans 2, and improving the reliability and stability of the portable energy storage power supply 100.

[0047] Please refer to Figure 3. In some embodiments, a dust filter 4 is connected to the end of the vent 1321 facing away from the receiving cavity 10.

[0048] When the cooling fan 2 is working, it guides external air to convect with the air inside the housing 10, and foreign objects such as dust mixed in the air will enter the housing 10. To avoid the impact of dust accumulation, dust filters 4 are connected to the ventilation openings 1321 of the two second side panels 132. The dust filters 4 can intercept dust and particulate matter, preventing them from adhering to the electronic components inside the housing 10. Dust accumulation can cause short circuits. The dust filters 4 reduce the risk of failure of the portable power storage power supply 100 due to dust accumulation and extend the overall service life of the portable power storage power supply 100.

[0049] Please refer to Figures 1 and 2. In some embodiments, the mounting housing 1 is also provided with handles 6. Specifically, the top cover 11 is connected to both ends with handles 6, which facilitates the user to carry the portable energy storage power supply 100 and improves portability.

[0050] Referring to Figure 1, in some embodiments, a first side panel 131 is provided with multiple charging ports 7. Specifically, both the first side panel 131 and the second side panel 132 are provided with charging ports 7 for user charging. For example, DC ports, AC ports, etc.

[0051] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
