Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic energy storage cabinets, and in particular to a solar photovoltaic energy storage cabinet. Background Art

[0002] The integrated photovoltaic, storage and charging system consists of distributed photovoltaics, power loads, distribution facilities, monitoring and protection devices. It is a small self-powered system that generates electricity through photovoltaic power generation. The excess electricity is stored in energy storage equipment and used for power supply or charging when needed. Among them, photovoltaic energy storage cabinets play a vital role in the integration of photovoltaic, storage and charging.

[0003] Photovoltaic energy storage cabinets can store excess electricity generated by photovoltaic power generation systems. When there is sufficient sunlight, photovoltaic panels convert solar energy into electricity. In addition to meeting immediate electricity needs, the excess electricity will be stored in the energy storage cabinet. In this way, during periods of insufficient sunlight or peak electricity consumption, the energy storage cabinet can release the stored electricity to meet electricity demand. At the same time, the photovoltaic energy storage cabinet can flexibly adjust energy output according to electricity demand and grid conditions through an intelligent control system. When the grid load is low, the energy storage cabinet can store more electricity; when the grid load is high or there is a sudden power outage, the energy storage cabinet can quickly release electricity to ensure the stability and reliability of the power supply.

[0004] Existing solar photovoltaic energy storage cabinets usually have poor heat dissipation performance. Long-term use will cause the battery to heat up severely, which can easily lead to fire and shorten the service life of the solar photovoltaic energy storage cabinet.

[0032] As described in the background art, existing solar photovoltaic energy storage cabinets generally have poor heat dissipation performance. Long-term use can cause severe heating of the battery, which can easily lead to fires and shorten the service life of the solar photovoltaic energy storage cabinet.

[0033] In order to solve this technical problem, the utility model provides a solar photovoltaic energy storage cabinet.

[0034] Specifically, please refer to Figure 1-4 A solar photovoltaic energy storage cabinet specifically includes: an energy storage cabinet body 1 and a battery module 11. The front side of the energy storage cabinet body 1 is fixedly connected to a rotating shaft 12, and the outer surface of the rotating shaft 12 is rotatably connected to a switch door 13.

The outer surface of the energy storage cabinet body 1 is installed with a second heat sink.

[0035] Through the operation of the water pump 23 in the first heat sink, the cooling water inside the water tank 21 flows into the inside of the guide groove 25 through the water inlet pipe 1 22 and the water inlet pipe 2 24, thereby absorbing and driving the heat generated by the battery pack module 11.

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. Example

[0039] Please refer to Figure 1-4 A solar photovoltaic energy storage cabinet includes an energy storage cabinet body 1 and a battery module 11. A rotating shaft 12 is fixedly connected to the front side of the energy storage cabinet body 1, and a switch door 13 is rotatably connected to the outer surface of the rotating shaft 12. A water tank 21 is fixedly connected to the lower surface of the energy storage cabinet body 1, and a first heat sink is fixedly connected to the outer surface of the water tank 21. A second heat sink is mounted on the outer surface of the energy storage cabinet body 1. The first heat sink includes a water inlet pipe 1 22, the lower end of which is fixedly connected to the water tank 21. Eight water inlet pipes 2 are fixedly connected to the outer surface of the water inlet pipe 1 22. Eight heat sinks 2 are fixedly connected to the inner surface of the energy storage cabinet body 1. The eight water inlet pipes 24 pass through the energy storage cabinet body 1 and are fixedly connected to the eight heat sinks 2. A water outlet pipe 2 is fixedly connected to the left side of the outer surface of the water tank 21. The outer surface of the water outlet pipe 2 is fixedly connected to eight water outlet pipes 26. The eight water outlet pipes 26 pass through the energy storage cabinet body 1 and are fixedly connected to the eight heat sinks 2. A guide groove 25 is provided within the heat sink 2, connecting the water tank 21, water inlet pipe 1 22, water inlet pipe 24, the guide groove 25, water outlet pipe 1 26, and water outlet pipe 2 27. A water pump 23 is mounted on the underside of the outer surface of water inlet pipe 1 22, while a radiator 28 is mounted on the underside of the outer surface of water outlet pipe 27. The water pump 23 and radiator 28 are fixedly mounted on either side of the water tank 21. Seven fixing blocks 29 are fixedly attached to both sides of the outer surface of the energy storage cabinet body 1.

[0040] Implementation process: The water pump 23 works to flow the cooling water inside the water tank 21 into the inside of the guide groove 25 through the water inlet pipe 1 22 and the water inlet pipe 2 24. Because the heat sink 2 is arranged on the upper and lower sides of the battery pack module 11, the cooling water absorbs the heat generated by the battery pack module 11 during the flow from the inside of the guide groove 25, and then passes through the water outlet pipe 1 26, the water outlet pipe 2 27 and the radiator 28, and releases the heat under the action of the radiator 28, so that it turns into cooling water again and flows into the inside of the water tank 21 to complete a cycle.

[0041] Implementation benefits: The heat generated by the battery module 11 is absorbed and taken away by the flow of cooling water inside the water tank 21 . Example

[0042] The second heat sink includes seven fans 31 located on the right side of the energy storage cabinet body 1. Seven heat dissipation holes 32 are defined on the left side of the energy storage cabinet body 1. The top surfaces of the seven heat sinks 2 are fixedly connected to a limit plate 3, and the battery module 11 slides on the inner surface of the limit plate 3. The fans 31 and heat dissipation holes 32 are located on either side of the battery module 11. A temperature detector 4 is mounted on the left side of the inner surface of the energy storage cabinet body 1.

[0043] Implementation process: The fan 31 starts working to draw external air into the energy storage cabinet body 1 to the right side of the battery module 11. The air then flows through the front and rear sides of the battery module 11 to the left side of the battery module 11 and flows through the heat dissipation holes 32, thereby driving the heat generated by the battery module 11. At the same time, the temperature inside the energy storage cabinet body 1 can be observed in real time through the setting of the temperature detector 4.

[0044] Implementation benefit: The heat generated by the battery module 11 is taken away by air flow.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
