[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Figure 1 This is a schematic diagram of the heat dissipation system of the energy storage device according to an embodiment of the present invention.

[0025] Energy storage devices may include energy storage converters.

[0026] like Figure 1 As shown, the energy storage device includes an internal cavity, which includes a first cavity and a second cavity. The heat dissipation system includes a first air-cooling module 100 and a heat dissipation vent 200. The first cavity is equipped with high-power devices and corresponding first air-cooling module 100 and heat dissipation vent 200. The second cavity is divided into a mixed air intake zone, a heat conduction zone and a mixed air outlet zone according to an H-shaped layout.

[0027] The heat dissipation vent 200 may include an air inlet a and an air outlet b. The first cavity is connected to the second cavity through the air inlet a and the air outlet b. Part of the air in the first cavity is connected to the second cavity through the heat dissipation vent 200 under the action of the first air-cooling module. The first air-cooling module 100 may include a fan, and the arrow in the figure indicates the airflow direction. The high-power device may be an IGBT (Insulated Gate Bipolar Transistor).

[0028] Among them, such as Figure 2a and 2b As shown, the heat conduction zone is functionally divided into an air contact conduction zone, a shell contact conduction zone, and a surface contact conduction zone, which are distributed in series or series-parallel configurations. Specifically, the second cavity is divided into a mixed air intake zone, a heat conduction zone, and a mixed air outlet zone according to an H-shaped layout. The left and right sides of the H-shape are the mixed air intake zone and the mixed air outlet zone, respectively, with the heat conduction zone in the middle. The heat conduction zone is functionally divided into an air contact conduction zone, a shell contact conduction zone, and a surface contact conduction zone. Furthermore, it should be noted that, as... Figure 2a and 2b As shown, the heat conduction zone can be divided into two areas by a partition.

[0029] Specifically, in one embodiment of this utility model, such as Figure 2aAs shown, the air contact conduction zone and the surface contact conduction zone are connected in series, and the air contact conduction zone and the surface contact conduction zone are connected in parallel with the shell contact conduction zone. In this distribution, a portion of the intake air in the mixed air intake zone can pass through the air contact conduction zone to the surface contact conduction zone, while the other portion can be directly transported to the shell contact conduction zone through an independent isolation duct. It should be noted that this distribution is more suitable for cases where the chassis size is larger in the lateral direction and smaller in the longitudinal direction. In another embodiment of this utility model, as... Figure 2b As shown, the air contact conduction zone, surface contact conduction zone, and shell contact conduction zone are connected in series. In this distribution, the three zones are located within the same air duct, resulting in continuous and concentrated airflow. It should be noted that this distribution is more suitable for chassis with a larger longitudinal dimension and a smaller lateral dimension. Therefore, it can be flexibly applied to design scenarios with different chassis sizes. Furthermore, the arrangement of the zones can be tailored to the heat distribution in different areas under actual cooling conditions, ensuring full utilization of the incoming airflow.

[0030] Among them, such as Figure 3a and 3b As shown, the heat dissipation system may further include a second air-cooling module 300, a heat exchanger 400, a heat dissipation module 500, and a potted inductor 600. The second air-cooling module 300 is located in the mixed air intake area, the heat exchanger 400 is located in the air contact conduction area, the second cavity is connected to the heat dissipation vent 200 through the heat exchanger 400, the heat dissipation module 500 is located in the surface contact conduction area, and the heat dissipation module 500 makes surface contact with the high-power device. The potted inductor 600 is located in the shell contact conduction area. It should be noted that a slot can be provided on the cavity wall of the first cavity, and the heat dissipation module 500 is located in the second cavity, which can achieve surface contact with the high-power device in the first cavity through the slot.

[0031] Specifically, the first cavity dissipates heat through air contact with the second cavity via heat exchanger 400, while the second cavity serves as the main air-cooled heat dissipation cavity and is connected to the outside.

[0032] In one embodiment of this utility model, the second air-cooling module 400 is embedded in the mixed air intake area. This embedded structure allows the second air-cooling module 400 to be individually removed during daily use, facilitating maintenance and providing a certain degree of dust and water resistance. The second air-cooling module 400 may include N fans ( Figure 3a and Figure 3b (Only 4 fans are shown in the image), where N is a positive integer; for example, N can be 4 or 5.

[0033] In addition, the mixed air outlet zone is located at the very end of the air duct. The air passes through the mixed air inlet zone, the heat conduction zone, and the mixed air outlet zone before being discharged from the mixed air outlet zone.

[0034] In one embodiment of this utility model, such as Figure 3a and 3b As shown, the heat exchanger 400 includes a heat exchange duct 410 and heat exchange outlet c and heat exchange inlet d disposed at both ends of the heat exchange duct 410. The heat exchange inlet d is connected to the inlet channel a, and the heat exchange outlet c is connected to the outlet channel b. It should be noted that the inlet channel is the channel for air entering the heat exchange duct 410, and the outlet channel is the channel for air exiting the heat exchange duct 410. Therefore, it can be understood that... Figure 3a and 3b As shown, when the airflow direction of the fan adjacent to the air outlet b changes, the positions of the air inlet and outlet will also change accordingly. Figure 3a and 3b When the airflow direction of the fan adjacent to the air outlet b changes, the air inlet a becomes the air outlet, and the air outlet b becomes the air inlet.

[0035] In one embodiment of this utility model, the heat exchanger 400 may further include heat exchange fins (not specifically shown in the figure). The heat exchange fins are disposed in the heat exchange air duct. The heat exchange fins increase the air contact area and can effectively cool the hot air in the first cavity, thereby achieving the purpose of efficient heat dissipation.

[0036] In one embodiment of this utility model, the potted inductor 600 may include a potted inductor shell. Within the shell contact conduction area, the heat-generating end is encapsulated in the potted inductor shell through a high thermal conductivity potting compound. The potted inductor shell has a serrated structure, which can effectively improve the heat dissipation effect.

[0037] In one embodiment of this invention, within the surface contact conduction area, the heat dissipation module 500 includes a heat sink, which makes surface contact with the high-power device. Thus, heat can be directly conducted to the lower surface of the heat sink through the surface contact, and then further dissipated via the heat sink fins to enhance the heat dissipation effect.

[0038] Therefore, in this embodiment of the invention, the second cavity adopts an H-shaped layout, which can divide the second cavity into different functional areas, namely, a mixed air intake area and a mixed air exhaust area on both sides, with the heat conduction area where the heat distribution is most concentrated contained between the two, so that the air intake in the second cavity can be fully utilized; the three different heat dissipation areas in the heat conduction area are arranged in series-parallel or series connection, which can be flexibly applied to different chassis size design scenarios. At the same time, the arrangement of the areas can be adjusted according to the heat situation of different areas under actual heat dissipation conditions, so that the air intake can be fully utilized; in addition, the heat exchanger is located in the air contact area, and its air inlet and outlet channels can connect the first cavity and the second cavity. In the first cavity, the fan direction at the channel opening can be adjusted as needed, and the operation is flexible; furthermore, the second air-cooling module in the mixed air intake area is embedded, and the number of fans can be changed according to the heat dissipation requirements. It can be individually extracted during daily use, which is convenient for maintenance and has a certain degree of dust and water resistance.

[0039] In summary, according to the heat dissipation system of the energy storage device according to the embodiment of this utility model, the energy storage device includes an internal cavity, which includes a first cavity and a second cavity. The first cavity is equipped with high-power devices and correspondingly arranged first air-cooling modules and heat dissipation vents. The first cavity is connected to the second cavity through the heat dissipation vents. The second cavity is divided into a mixed air intake zone, a heat conduction zone, and a mixed air outlet zone according to an H-shaped layout. The heat conduction zone is further divided into an air contact conduction zone, a shell contact conduction zone, and a surface contact conduction zone according to function. The air contact conduction zone, shell contact conduction zone, and surface contact conduction zone are distributed in series or in series-parallel configuration. Thus, the internal cavity of the energy storage device is isolated into two cavities, and independent heat dissipation channels are provided, improving heat dissipation efficiency. Furthermore, the H-shaped layout of the second cavity into different functional areas ensures that the air intake within the second cavity is fully utilized, thereby further improving heat dissipation efficiency.
