Description

Technical Field

[0001] This invention relates to the field of energy storage power technology, specifically to an energy storage power heat dissipation device with waterproof and dustproof functions. Background Technology

[0002] As a power storage device, energy storage power supplies experience internal temperature increases during operation due to heat generated by the battery pack assembly and inverter. This can affect the normal operation of the power supply, thus requiring additional cooling structures. Currently, energy storage power supplies are not dustproof or waterproof. Accumulated dust inside the power supply will impair heat dissipation, while water ingress will disrupt its operation and ultimately reduce its lifespan. Summary of the Invention

[0003] The present invention aims to provide a heat dissipation device for energy storage power supply with waterproof and dustproof functions, so as to solve the problem of poor heat dissipation and waterproof performance of existing energy storage power supplies.

[0004] The basic solution provided by this invention is: a heat dissipation device for energy storage power supply with waterproof and dustproof functions, including a housing and a battery pack assembly disposed inside the housing, the housing being provided with an air inlet and an air outlet; wherein: a cooling fan is also provided inside the housing, the air inlet is provided with multiple air inlet baffles that are initially closed but open when dissipating heat inside the housing, and the air outlet is provided with multiple air outlet baffles that are initially closed but open when dissipating heat.

[0005] The beneficial effect of the basic solution is that existing heat dissipation windows have fixed air inlets and outlets, allowing external dust or splashes of water to enter the energy storage power source even when ventilation is not needed, thus affecting its normal operation. Therefore, compared to existing heat dissipation structures, this solution incorporates an inlet baffle at the air inlet and an outlet baffle at the air outlet. In the initial state, when the battery pack assembly is not supplying power, both the inlet and outlet baffles are closed, effectively sealing the casing. When the energy storage power source needs cooling, the cooling fan activates, causing the outlet baffle to open outwards. Once open, internal air is expelled by the cooling fan, creating a negative pressure environment inside the casing. When the pressure is high, the air inlet baffle opens, allowing outside air to enter the housing. This creates airflow inside the housing, carrying away heat. When heat dissipation is not required, i.e., in the initial state where the energy storage power supply does not need cooling, the air inlet and outlet baffles return to their initial state, closing the air inlet and outlet respectively. The housing is sealed, preventing external dust or splashes of water from entering, thus achieving waterproof and dustproof functionality.

[0006] Furthermore, the air inlet baffle and air outlet baffle are hinged to the inner wall of the housing. Beneficial effect: In this design, hinged connection of the air inlet baffle and air outlet baffle to the housing facilitates their swinging motion, thereby opening the air inlet and air outlet, resulting in a simple structure.

[0007] Furthermore, multiple air inlet baffles and multiple air outlet baffles are opened or closed simultaneously. Beneficial effect: In this solution, the simultaneous opening or closing of multiple air inlet and outlet baffles reduces whistling noise caused by opening or closing at different times, thereby improving the user experience.

[0008] Furthermore, a drive mechanism is also provided inside the housing. One end of the drive mechanism is connected to the air inlet baffle, and the other end is connected to the air outlet baffle. The drive mechanism drives the air inlet and air outlet baffles to open or close. Beneficial effect: In this solution, the air inlet and air outlet baffles are driven using a drive mechanism, resulting in a simple structure.

[0009] Furthermore, a limiting component is provided on the inner wall of the housing to restrict the opening angle of the air inlet and outlet baffles. Beneficial effect: Considering that when the opening angle of the air inlet and outlet baffles is too large, external dust or splashing water can enter the housing from the air inlet and outlet, the limiting component in this solution can limit the opening angle of the air inlet and outlet baffles, thereby reducing the probability of external dust or splashing water entering the housing and further ensuring the normal operation of the energy storage power supply.

[0010] Furthermore, both the air inlet and outlet are equipped with limiting components, which include a mounting groove and a mounting plate. The mounting plate is located within the mounting groove and can move within it. Multiple connecting rods are mounted on the mounting plate, and these connecting rods are hinged to the air outlet baffle and the air inlet baffle. Beneficial effects: In this solution, taking the air inlet baffle as an example, when the air inlet baffle swings, the connecting rods hinged to it move, causing the mounting plate to move. During the movement of the mounting plate, when it abuts against the edge of the mounting groove, the mounting plate, restricted by the groove, can no longer move, thus preventing the air inlet baffle from swinging further. This achieves the purpose of limiting the opening angle of the air inlet baffle. Moreover, during the movement of the mounting plate, all the connecting rods on the mounting plate will cause all the air inlet baffles to swing together at the same angle, which also avoids the whistling sound caused by multiple air inlet baffles having different opening angles during air intake. The structure is simple.

[0011] Furthermore, the drive structure includes a drive rod and two sets of connecting assemblies located at both ends of the drive rod, moving simultaneously towards or away from each other. One end of each connecting assembly is connected to the drive rod, the other end of one set of connecting assemblies is connected to an air inlet baffle, and the other end of the other set of connecting assemblies is connected to an air outlet baffle. Beneficial effects: In this solution, the drive rod and the connecting assemblies at both ends form a lever structure. Therefore, after the drive rod rotates, it can drive the air inlet and air outlet baffles at both ends of the drive rod to move towards or away from each other. The structure is simple and can reduce the production cost of the product.

[0012] Furthermore, the connecting assembly includes a connecting plate and a connecting rod. One end of the connecting rod is connected to one end of the drive rod, and the other end is connected to the air inlet baffle or air outlet baffle. Beneficial effect: In this solution, the connecting assembly, composed of a connecting plate and a connecting rod, has a simple structure.

[0013] Furthermore, the drive rod is connected to the inner wall of the upper surface of the housing via a connecting post, with the drive rod sleeved at the bottom of the connecting post. Beneficial effect: In this design, the drive rod is positioned at the upper end of the housing using a connecting post, thereby avoiding interference between the drive structure and other components within the housing.

[0014] Furthermore, the middle part of the drive rod is connected to the connecting column. Beneficial effect: In this solution, after the middle part of the drive rod is connected to the connecting column, it ensures that the drive rod drives the air inlet and outlet plates to move the same distance, thus ensuring that the opening areas of the air inlet and outlet are the same, avoiding whistling noise and improving the user experience.

[0015] Furthermore, the air inlet and outlet are located on opposite sides of the casing. Beneficial effect: In this design, placing the air inlet and outlet on opposite sides of the casing ensures a larger area for both, allowing more air to enter the casing and effectively dissipate heat, thus improving heat dissipation.

[0016] Furthermore, dust filters are installed inside the casing near the air inlet and outlet. Beneficial effect: In this design, the dust filters prevent rainwater and dust from entering the casing, further achieving the purpose of dust and water protection.

[0017] Furthermore, a partition and an inverter are installed inside the housing. The two ends of the partition are connected to the inner wall of the housing, and the battery pack assembly and the inverter are located on different sides of the partition. Beneficial effect: In this design, the partition divides the interior of the housing into two layers, and the battery pack assembly and the inverter are respectively located in different layers of the housing, thereby preventing heat transfer between the upper and lower layers.

[0018] Furthermore, the upper ends of the air inlet baffle and the air outlet baffle are hinged to the housing. Beneficial effect: In this design, after the upper ends of the air inlet baffle and the air outlet baffle are hinged to the housing, when the air inlet baffle and the air outlet baffle are not subjected to air thrust, they will swing back to their initial positions under their own gravity, thereby sealing the housing and achieving dustproof and waterproof effects. No additional recovery structure is required, saving production costs.

[0019] Furthermore, both the air inlet and outlet baffles open outwards. Beneficial effect: In this design, the outward-opening air inlet and outlet baffles can block some external dust or splashes of water, thereby enhancing the product's dustproof and waterproof performance.

[0020] Furthermore, in the plurality of air inlet baffles and / or air outlet baffles, the upper air inlet baffle and / or air outlet baffle overlaps with the lower air inlet baffle and / or air outlet baffle, and the overlapping portion is provided with a fitting structure. Beneficial effect: In this solution, the fitting structure on the overlapping portion increases the sealing performance of the air inlet baffle and / or air outlet baffle when closed, thereby improving the waterproof and dustproof effect of the product.

[0021] Furthermore, the matching structure includes a first matching part disposed at the upper end of the air inlet baffle and / or air outlet baffle, and a second matching part disposed at the lower end of the air inlet baffle and / or air outlet baffle and matching the first matching part. Beneficial effect: In this solution, the matching structure is composed of the first matching part and the second matching part, resulting in a simple structure. Attached Figure Description

[0026] The following detailed description illustrates the specific implementation method:

[0027] The reference numerals in the accompanying drawings include: housing 1, air outlet 2, air outlet baffle 21, limiting component 22, air inlet 3, air inlet baffle 31, dustproof net 4, cooling fan 5, partition 51, battery pack assembly 6, inverter 61, connecting rod 71, connecting column 72, and drive rod 73.

[0028] The basic implementation examples are as follows: Figures 1-4 As shown: A heat dissipation device for energy storage power supply with waterproof and dustproof functions includes a housing 1 and a battery pack assembly 6 and an inverter 61 disposed inside the housing 1. A partition 51 is arranged horizontally inside the housing 1. The partition 51 is located in the middle of the housing 1. The two ends of the partition 51 are connected to the inner wall of the housing 1, so that the partition 51 can divide the interior of the housing 1 into upper and lower layers. The battery pack assembly 6 is located in the lower layer of the housing 1, and the inverter 61 is located in the upper layer.

[0029] An air inlet 3 is provided on one side of the housing 1, and an air outlet 2 is provided on the other side. The air inlet 3 is equipped with multiple air inlet baffles 31 that are initially closed but open outwards during heat dissipation. The air outlet 2 is equipped with multiple air outlet baffles 21 that are initially closed but open outwards during heat dissipation. The multiple air inlet baffles 31 and multiple air outlet baffles 21 can be opened or closed simultaneously. Specifically, in this embodiment, the upper ends of both the air inlet baffles 31 and the air outlet baffles 21 are hinged to the interior of the housing 1. A limiting component 22 is also provided on the inner wall of the housing 1 to restrict the opening angle of the air inlet baffles 31 and the air outlet baffles 21. In this embodiment, both the air inlet 3 and the air outlet 2 are equipped with the limiting component 22. Figure 3 As shown, the limiting component 22 includes a mounting groove and a mounting plate. The mounting plate is located in the mounting groove and can move within the mounting groove. The mounting plate is provided with multiple connecting rods, which are hinged to the air outlet baffle 21 and the air inlet baffle 31.

[0030] Among the multiple air inlet baffles 31 and / or air outlet baffles 21, the upper air inlet baffle 31 and / or air outlet baffle 21 and the lower air inlet baffle 31 and / or air outlet baffle 21 have an overlapping portion, and the overlapping portion is provided with a fitting structure, specifically, as shown in Figure 3 As shown, the matching structure includes a first matching part disposed at the upper end of the air inlet baffle 31 and / or the air outlet baffle 21, and a second matching part disposed at the lower end of the air inlet baffle 31 and / or the air outlet baffle 21 and matching with the first matching part. In this embodiment, both the air inlet baffle 31 and the air outlet baffle 21 are provided with matching structures.

[0031] A cooling fan 5 is installed inside the housing 1. In this embodiment, the cooling fan 5 is powered by the battery pack assembly 6, and the cooling fan 5 is triggered to start simultaneously when the battery pack assembly 6 is working. A dust filter 4 is also installed inside the housing 1 near the air inlet 3 and the air outlet 2. Preferably, in this embodiment, cooling fans 5 are installed on both the upper and lower layers inside the housing 1, and the cooling fans 5 on the upper and lower layers use fans of different power according to the heat dissipation requirements of the inverter 61 and the battery pack assembly 6.

[0032] A drive mechanism is also provided inside the housing 1. One end of the drive mechanism is connected to the air inlet baffle 31, and the other end is connected to the air outlet baffle 21. The drive mechanism drives the air inlet baffle 31 and the air outlet baffle 21 to open or close. Figure 4As shown, in this embodiment, the driving structure includes a driving rod 73 and two sets of connecting components located at both ends of the driving rod 73 that move simultaneously toward or away from each other. One end of each set of connecting components is connected to the driving rod 73. The other end of one set of connecting components is connected to an air inlet baffle 31, and the other end of the other set of connecting components is connected to an air outlet baffle 21. The connecting components include a connecting plate and a connecting rod 71. One end of the connecting rod 71 is connected to one end of the driving rod 73, and the other end is connected to the air inlet baffle 31 or the air outlet baffle 21. The middle part of the driving rod 73 is sleeved on the bottom of the connecting post 72, so that the driving rod 73 can be connected to the inner wall of the upper surface of the housing 1 through the connecting post 72.

[0033] The specific implementation process is as follows: In this embodiment, when the energy storage power supply does not require heat dissipation, it is in the initial state by default. In the initial state, the air inlet baffle 31 and the air outlet baffle 21 will automatically move downward and remain vertical under their own gravity, thereby blocking the air inlet 3 and the air outlet 2. External splashes of water or dust and other debris cannot enter the interior of the housing 1, thus achieving the effect of dustproof and waterproof.

[0034] When the energy storage power supply needs to dissipate heat, the cooling fan 5 starts, blowing the air outlet baffle 21 open, the air inside the housing 1 is blown out, and a negative pressure state appears inside the housing 1. Then the movable plate 23 opens inward, and the outside air enters the housing 1 through the opened movable plate 23, and the air inside the housing 1 flows normally.

[0035] When the air outlet baffle 21 opens, it pulls the connecting rod 71 connected to the air outlet baffle 21 to move outward, which in turn pulls the drive rod 73 to rotate counterclockwise. The counterclockwise rotation of the drive rod 73 pushes the connecting rod 71 connected to the air inlet baffle 31 to move outward. Thus, the air inlet baffle 31 opens outward under the push of the connecting rod 71. At this time, the air inlets 3 and air outlets 2 on both sides of the housing 1 open. Air enters the housing 1 from the air inlets 3 and flows out of the housing 1 from the air outlets 2, thereby carrying away the heat inside the housing 1 and achieving heat dissipation. Moreover, during the opening process, when the air inlet baffle 31 and the air outlet baffle 21 abut against the limiting component 22 set diagonally above, the air inlet baffle 31 and the air outlet baffle 21 will no longer swing and will maintain their current angle. During this process, the dustproof net 4 can block larger impurities such as dust in the air, thereby preventing impurities from entering the housing 1 during the use of the energy storage power supply.

[0036] When the energy storage power supply does not require heat dissipation, the cooling fan 5 stops working. As a result, the air inlet baffle 31 and the air outlet baffle 21 will swing back to their initial positions under their own gravity, resealing the housing 1. At the same time, the matching structure formed by the first matching part and the second matching part further enhances the sealing effect.
