Description

Technical Field

[0001] The invention relates to the technical field of battery packs, and in particular to a photovoltaic energy storage battery pack that is easy to dissipate heat. Background Art

[0002] Photovoltaic energy storage battery is a kind of energy storage technology, which mainly includes the structure of photovoltaic panels and energy storage batteries. It uses solar photovoltaic panels to convert sunlight into electrical energy, and then stores the electrical energy in energy storage batteries. Energy storage batteries mostly use lead-acid batteries or lithium batteries. All energy storage batteries have resistance inside, which will generate heat when performing energy storage work, and the heat will continue to rise. Excessive temperature will affect the energy storage efficiency and service life of the battery, and photovoltaic panels also need to dissipate heat in time, because photovoltaic panels convert solar energy into electrical energy, and the heat in solar energy will continue to be added to the photovoltaic panels. The higher the temperature on the photovoltaic panels, the more it will affect its conversion efficiency, and it will also cause accelerated loss of internal components. Therefore, it is necessary to dissipate heat for both photovoltaic panels and energy storage batteries at the same time to ensure efficient storage of electricity and the overall service life of photovoltaic energy storage batteries.

[0003] The existing heat dissipation of photovoltaic energy storage battery groups is mostly cooled by natural wind, and there are also air cooling equipment for heat dissipation, which needs to consider the outside temperature.

The problem solved by the present invention is to use natural wind for cooling or heat dissipation of air-cooled equipment, and the outside temperature is too high. It does not achieve a good heat dissipation effect, has low heat dissipation efficiency and high maintenance cost. The present invention forms a stable support structure through the combination of the above components, enhances the stability of the equipment frame, and facilitates the installation and disassembly of the overall structure. The cover plate 11 installed on the upper end of the equipment frame 1 realizes a detachable design, which is convenient for maintenance and replacement of the battery pack 13. The battery pack 13 distributed in an array is electrically connected, which improves the overall performance of the battery pack 13.

The cooling efficiency is improved, and the heat dissipation cost is reduced. The circulation of the coolant is achieved through the liquid cooling structure 31, and the heat generated by the battery pack 13 is effectively absorbed. The air cooling structure 32 with a double structure enables the rotation of the fan to generate airflow, thereby increasing the heat dissipation area and accelerating the heat dissipation.
