Description

Technical Field

[0001] The present application relates to power generation and energy storage technology, and in particular to an integrated photovoltaic energy storage machine. Background Art

[0002] The photovoltaic energy storage integrated machine generally includes an inverter and an energy storage battery pack. The inverter is used to convert the direct current transmitted by the solar photovoltaic panel or the energy storage battery pack into alternating current output, and the energy storage battery pack is used to store the direct current output by the solar photovoltaic panel and output the direct current to the inverter.

[0003] When the inverter and the energy storage battery pack are working, a large amount of heat will be generated. However, in the related technology, only air cooling is usually used for heat dissipation, and the cooling effect is poor, which needs to be improved. Summary of the invention

[0004] In order to improve the heat dissipation effect, the present application proposes a photovoltaic energy storage integrated machine.

[0005] A photovoltaic energy storage integrated machine, comprising a housing and a circuit board, wherein a photovoltaic controller is arranged on the housing, and electrical components are arranged on the circuit board, and further comprising

[0006] The heat dissipation mechanism includes a bidirectional heat dissipation plate and a unidirectional heat dissipation plate. The bidirectional heat dissipation plate is arranged on the circuit board on the same side as the electrical component, and the unidirectional heat dissipation plate is arranged on the circuit board on the side away from the bidirectional heat dissipation plate. The unidirectional heat dissipation plate penetrates the housing and is exposed to the outside.

[0007] The water cooling mechanism comprises a water storage tank arranged on the housing, the water storage tank is connected to a nozzle through a pipeline, and the nozzle is arranged above the exposed part of the heat dissipation structure of the electric board;

[0008] The fire prevention mechanism comprises a gas storage tank and a generating box. The generating box is arranged on the lower end surface of the shell, the generating box is connected to the water storage tank through a pipeline, solid sodium bicarbonate is arranged in the generating box, the gas storage tank is arranged on the upper end surface of the shell, the gas storage tank is connected to the generating box through a pipeline, an air outlet pipe is arranged on the gas storage tank, and the air outlet pipe is inserted into the shell.

[0009] By adopting the above technical solution, the bidirectional heat sink is used to dissipate heat from the electrical components of the photovoltaic energy storage machine, reducing the temperature generated by the inverter and the energy storage battery pack. The unidirectional heat sink transfers the heat generated on the electrical plate to the outside world and reduces the heat generated by the photovoltaic energy storage machine during operation. The heat dissipation mechanism can directly dissipate heat from the photovoltaic energy storage machine's heating mechanism, making the photovoltaic energy storage machine's heat dissipation effect obvious, and minimizing the risk of combustion and explosion due to excessive temperature in the photovoltaic energy storage machine.

When the optical storage machine accidentally burns, the existing technology generally adopts the method of spraying flame retardant powder to protect the optical storage machine. Although it can effectively protect the optical storage machine from combustion and explosion, it will also cause a certain probability of scrapping the optical storage machine. The present application protects the optical storage machine by spraying the gas in the gas tank inside the optical storage machine, which can avoid the explosion of the optical storage machine as much as possible and avoid the scrapping of the optical storage machine as much as possible.
