Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, specifically to a heat dissipation structure for a mobile emergency power supply battery pack. Background Technology

[0002] With the widespread use of large-capacity battery packs in mobile emergency power cabinets, their increased weight places higher demands on the strength of the cabinet's support structure and its heat dissipation performance. In existing technologies, to cope with the weight load of the battery packs, the support columns often use thickened metal materials or dense frame designs. While this ensures mechanical strength, it also reduces internal space, hinders the layout of heat dissipation airflow channels, and exacerbates heat accumulation during battery pack operation. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a battery pack heat dissipation structure for a mobile emergency power supply that ensures heat dissipation while guaranteeing the strength of the cabinet.

[0004] Therefore, this utility model provides a battery pack heat dissipation structure for a mobile emergency power supply, including a cabinet and a heat dissipation plate. The cabinet includes at least one rectangular frame, and the rectangular frame includes pillars distributed at its four corners. Multiple support plates for placing the battery pack are installed on the inner wall of the pillars. The multiple support plates are spaced apart along the height direction of the cabinet. Multiple circular holes are opened on the pillars and spaced apart along their height direction. Circular iron pipes are welded and fixed at the circular holes. The direction of the iron pipes is parallel to the length direction of the battery pack. The heat dissipation plate is installed on the front and rear sides of the cabinet, and the heat dissipation plate is located between two of the pillars.

[0005] The heat sink has a mesh pattern.

[0006] A flow guiding structure is installed between the heat sink and the battery pack.

[0007] The flow guiding structure includes a flow guiding frame, which is correspondingly arranged with the heat sink; and a plurality of flow guiding plates, which are spaced apart along the height direction of the flow guiding frame, and the flow guiding plates have a flow guiding surface that is inclined upward from the side adjacent to the heat sink towards the inside.

[0008] A fan is installed on the front side of the battery pack near the cabinet.

[0009] The technical solution of this utility model has the following advantages:

[0010] 1. The battery pack heat dissipation structure provided by this utility model has multiple circular holes spaced apart along its height on the support column. Circular iron pipes are welded and fixed at the circular holes. The direction of the iron pipes is parallel to the length direction of the battery pack. The iron pipes ensure both the strength of the support column and the ventilation volume. After passing through the heat dissipation plate, the external air flows through the circular iron pipes on both sides of the battery pack, thereby dissipating heat from the battery pack. This results in good heat dissipation effect.

[0011] 2. The battery pack heat dissipation structure provided by this utility model includes a flow guiding frame and multiple flow guiding plates. The multiple flow guiding plates are distributed at intervals along the height direction of the flow guiding frame. The flow guiding plates have a flow guiding surface that is inclined upward from the side adjacent to the heat dissipation plate towards the inside. In this way, water from the outside will flow down along the flow guiding surface instead of directly entering the cabinet. This ensures ventilation while also ensuring a certain degree of waterproof performance. Attached Figure Description

[0024] Example

[0025] This embodiment provides a battery pack heat dissipation structure for a mobile emergency power supply, such as... Figure 1 As shown, it includes cabinet 1, heat dissipation plate 7, and airflow guiding structure.

[0026] Cabinet 1, such as Figure 2 As shown, the cabinet 1 includes multiple rectangular frames, each frame comprising pillars 2 at its four corners. Multiple support plates 4 for placing battery packs 3 are mounted on the inner walls of the pillars 2. These support plates 4 are spaced apart along the height of the cabinet 1. Figure 3 and Figure 4 As shown, the support column 2 has multiple circular holes 5 spaced apart along its height direction. A circular iron pipe 6 is welded and fixed at each of the circular holes 5. The direction of the iron pipe 6 is parallel to the length direction of the battery pack 3. In this embodiment, the support column 2 is a steel beam, and a fan is installed on the front side of the battery pack 3 near the cabinet 1.

[0027] Heat dissipation plate 7 is installed on the front and rear sides of the cabinet 1, and the heat dissipation plate 7 is located between the two support columns 2. The heat dissipation plate 7 has mesh holes 8 formed on it.

[0028] A flow guiding structure is disposed between the heat sink 7 and the battery pack 3, such as... Figure 5 and Figure 6 As shown, the flow guiding structure includes: a flow guiding frame 9, which is correspondingly arranged with the heat sink 7; and a plurality of flow guiding plates 10, which are spaced apart along the height direction of the flow guiding frame 9. Each flow guiding plate 10 has a flow guiding surface 11 that is inclined upward from the side adjacent to the heat sink 7 toward the inward side.

[0029] The battery pack heat dissipation structure provided by this utility model has multiple circular holes 5 spaced apart along the height direction on the support column 2. Circular iron pipes 6 are welded and fixed at the circular holes 5. The direction of the iron pipes 6 is parallel to the length direction of the battery pack 3. The iron pipes 6 ensure the strength of the support column 2 while ensuring the ventilation volume. After passing through the heat dissipation plate 7, the external air flows through the circular iron pipes on both sides of the battery pack 3, thereby dissipating heat from the battery pack 3. This results in good heat dissipation effect.
