Description

Technical Field

[0001] This utility model relates to the field of energy storage system technology, and in particular to a PCS power battery device. Background Technology

[0002] Energy storage converters (PCS) generate a significant amount of heat during operation. Excellent heat dissipation performance is crucial for ensuring reliable operation. As a vital component of new energy storage systems, the PCS connects the energy storage medium to the power grid for energy exchange and also connects the energy storage medium to the load for independent power supply. Power modules, the core component of the PCS, are responsible for power conversion and control. They also generate substantial heat during operation. The main power devices in the power modules are IGBTs, which experience temperature increases during operation and require heat sinks for cooling to ensure safe and normal operation. Current air-cooling methods rely on direct fan blowing, which cannot ensure consistent airflow across all power modules, resulting in uneven heat dissipation and impacting performance.

[0025] like Figures 1-5 As shown, this utility model provides a PCS power battery device, which includes a housing 1, a front panel 2, a rear panel 3, a power supply board 7, and a fan mounting bracket 4. The housing 1 has a "П" structure, including a mounting base plate and side plates correspondingly arranged on both sides of the mounting base plate. The mounting base plate and the two side plates form a "П" structure, with open ends at both the front and rear ends. The front panel 2 is connected to the open end of the front side of the housing 1, and the rear panel 3 is connected to the open end of the rear side of the housing 1. Both the front panel 2 and the rear panel 3 are perforated mesh plates. The height of the front panel 2 is less than the height of the rear panel 3. The height of the front panel 2 is the same as the height of the cooling fan 5. A wiring panel 13 is correspondingly arranged at the top front. The front panel 2 serves as an air inlet, and the rear panel 3 serves as an air outlet. Cooling air enters from the front panel 2 and exits through the housing 1 and the rear panel 3.

[0026] like Figures 1-3 As shown, multiple heat sinks 9 are arranged side-by-side along the width of the power supply board 7. Each heat sink 9 is connected to a power device 10, and the front and rear ends of the heat sink 9 are respectively positioned to correspond to the front panel 2 and the rear panel 3. A PC air duct plate 6 is fastened to each heat sink 9, and a heat dissipation air duct 11 is formed around the heat sink 9 on the inner side of the PC air duct plate 6. A fan mounting bracket 4 is positioned between the heat sink 9 and the front panel 2, and a cooling fan 5 is mounted on the fan mounting bracket 4 corresponding to each heat sink 9. The air outlet of the cooling fan 5 is aligned with the inlet of the corresponding heat dissipation air duct 11. This utility model provides a novel heat dissipation air duct 11 structure for the power supply board 7. Through the cooperation of the PC air duct plate 6 and the independent fan, it ensures that the airflow speed is not lost when the cold air passes through each power device 10 of the power supply board 7, ensuring that the heat exchange airflow of each device is consistent, achieving uniform heat dissipation of the heat sink 9, and ensuring the safe and efficient operation of the power device 10.

[0027] In one specific embodiment, such as Figures 4-5 As shown, the heat sink 9 includes four heat sinks 9 arranged side by side along the width direction of the power supply board 7. Each pair of heat sinks 9 forms a group, and there are two groups in total. They are distributed at both ends of the power supply board 7. Multiple resistor components 8 are arranged between the two groups of heat sinks 9 on the power supply board 7. A cooling fan 5 is arranged on the fan mounting bracket 4 corresponding to the resistor components 8. The cooling fan 5 directly blows heat to the resistor components 8.

[0028] In one specific embodiment, such as Figure 4 As shown, the inner side of the fan mounting bracket 4 is equipped with air duct plate limiting brackets 12 corresponding to the heat sinks 9 one-to-one. The PC air duct plate 6 has an L-shaped structure and multiple mounting holes 61 are provided on it. It can be fixedly connected to the air duct plate limiting brackets 12 through the mounting holes 61. Two PC air duct plates 6 are spliced ​​together on a set of heat sinks 9 to form a heat dissipation air duct 11. It should be noted that the specific shape of the PC air duct plate 6 is not limited to the above structure. It can also adopt a "Π" shaped structure, sheet material, etc., and form the heat dissipation air duct 11 by snap-fit ​​or splicing.

[0029] The installation sequence of the various components of this utility model is as follows:

[0030] Place housing 1 on the platform. Install front panel 2 and rear panel 3 sequentially on the front and rear sides of housing 1. Then, install five cooling fans 5 on fan mounting brackets 4. Install air duct plate limiting bracket 12 on fan mounting brackets 4 as well. Place fan mounting brackets 4 on the mounting base of housing 1. Install power devices 10 on heat sinks 9. Install heat sinks 9 on power power supply boards 7. Install power circuit boards on the mounting base of housing 1. Finally, install PC air duct plates 6 on heat sinks 9 through mounting holes to complete the PCS power supply device installation. Each of the four cooling fans 5 has an independent air duct to ensure effective heat dissipation for the power devices 10 on each heat sink 9. The cooling fan 5 in the middle directly blows heat to the resistor components, ensuring that each device on the power board has a reasonable airflow. This prevents airflow loss when the cool air enters through the air inlet and passes through the heat-generating devices, ensuring effective and sufficient heat dissipation, stable component module performance, and thus protecting the energy storage converter for efficient and reasonable operation.

[0031] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
