Description

Technical Field

[0001] The utility model relates to the field of a photovoltaic power supply system, in particular to a cooling module of the photovoltaic power supply system. Background Art

[0002] At present, electric vehicles are very popular in China, so that battery manufacturers are stepping up the production of various types of batteries to meet the market demand. It can be seen that various types of batteries in China have already flooded every corner of society. However, for this reason, the whole society is also flooded with various types of batteries that have been replaced. It may not be correct to say that they are replaced, because many batteries are most likely removed from scrapped electric vehicles, but their functions are still normal, but their originally set power has been reduced due to various factors. For these batteries, or battery packs, some industry players have thought of combining them with photovoltaic projects to serve as energy storage batteries after photovoltaic batteries generate electricity; once this idea was proposed, it immediately received great support from the industry players.

[0003] At present, the energy storage batteries used for photovoltaics basically use the same battery packs as new energy vehicles to store energy, and these batteries all use brand new battery packs for safety reasons. Although there is no problem with using brand new battery packs as photovoltaic energy storage batteries, if you think about the problem more deeply, you will find that among the various new and old batteries currently on the market, those old batteries, although they have been used for a period of time, the energy storage capacity has also decreased due to various factors, but, overall, this type of battery still has complete functions, but it may not be comparable to brand new batteries in terms of efficiency, but, when it comes to energy storage, this type of battery can indeed still achieve the assigned task.

[0004] Since this type of battery or battery pack can still achieve the assigned task, why are there not many companies in the market that use this method to introduce this technology? This involves the problem of safety hazards; as mentioned above, this type of battery or battery pack is not as effective as a new battery in terms of working efficiency, so when using it, if these batteries are charged / discharged in the same way as other new batteries, it is very likely that the chemical reactions inside the so-called [second-hand] batteries during regular charging / discharging will definitely be different from those of new batteries. For example: when a new battery is charged / discharged internally, the overall temperature may change due to chemical reactions; similarly, these second-hand batteries will also have variations in overall temperature during charging / discharging. It is conceivable that the temperature changes of these [second-hand] batteries are absolutely different from those of new batteries. Therefore, if regular charging / discharging is performed again, and batteries of different ages are treated equally, during the entire charging / discharging process, those [second-hand] batteries will definitely cause safety problems due to rapid temperature rise. In order to solve the problem that batteries of different ages generate different temperatures when charging / discharging, some industry insiders have proposed a method for intelligent management of battery systems. This method is to first determine the [performance] of the battery based on the various parameters of the battery, and then judge the working capacity of the battery based on the performance after this determination, and charge / discharge the battery based on the final working capacity. This method completely determines the working capacity of the battery based on the various parameters of the battery, and then charges / discharges it. In this case, the working environment of the battery is absolutely below its ability to withstand, so the probability of danger is greatly reduced. However, since this method has no direct relationship with the content of this application, its detailed content will not be described in detail. Utility Model Content

[0005] The main problem solved by the utility model is the safety concern caused by the heating of the battery. When the battery forms a battery cluster (multiple batteries are stacked vertically and connected together, or connected horizontally in parallel) for storing energy, it contains batteries of various ages, so that the temperature of each individual battery will be different, which will cause hidden dangers in energy management.

[0025] See also Figure 1 and Figure 2 As shown, the utility model proposes a cooling module of a photovoltaic power supply system to solve the above problems. The cooling module selectively includes a housing 11, and the housing 11 has a plurality of compartments 12 each of which can accommodate a battery cluster.

[0026] A battery cluster 10 is composed of a plurality of batteries 100 stacked vertically or connected in parallel. In this embodiment, a battery cluster 10 is formed by stacking a plurality of batteries 100 vertically. After the battery cluster 10 is stacked, it is placed in a compartment 12 in the housing 11. As can be seen from the figure, there are eight compartments 12 in the housing 11, four on the left and four on the right, and the compartments are separated by partitions (shown but not marked) in the middle; however, the number of compartments 12 can be appropriately adjusted according to the size of the battery cluster 10, or can be separated into different configurations according to needs.

[0027] Figure 3It is shown that the cooling module provided by the present invention is also provided with a plurality of cooling tubes 20 in the housing 11. The cooling tubes 20 are divided into an input main tube 21 and an output main tube 22; the input main tube 21 is further divided into a plurality of input cooling tubes 211, and the output main tube 22 is further divided into a plurality of output cooling tubes 221. Each input cooling tube 211 corresponds to a separate section 12; at the same time, each output cooling tube 221 also corresponds to a separate section 12, and corresponds to and is connected with the individual input cooling tube 211 corresponding to the individual section 12. Furthermore, as mentioned above, each of the output cooling pipes 221 corresponds to another of the sections 12, however, each of the output cooling pipes 221 is connected to other output cooling pipes 221 at one end thereof, and is connected to the output main pipe 22; it is particularly important to note that each of the input cooling pipes 211 is arranged to be wrapped around the outside of the corresponding section 12, and at the same time, the casing 11 may be removed under certain specific conditions, leaving only the internal section 12 and the input main pipe 21, the output main pipe 22, and the plurality of sets of input / output cooling pipes 211, 221.

[0028] Cooperate with Figure 1 , Figure 2 As shown, according to this arrangement, it can be seen that when each of the input cooling pipes 211 is wrapped around the outside of the corresponding interval 12, and the battery cluster 10 is arranged in the interval 12, the temperature rise generated by each of the battery clusters during operation can be effectively cooled down by the cooling water or cooling gas contained in the input cooling pipe 211 surrounding the outside of the interval 12; after the cooling water or cooling gas cools down the battery cluster 10 with the temperature rise, the excess heat will be continuously transferred to the output cooling pipe 221 by the cooling water or cooling gas, and finally transferred to the outside of the module by the output main pipe 22. Since the excess heat is continuously exchanged by the cooling water or cooling gas, the operating temperature of each of the battery clusters 10 can be maintained within a stable range, and thus it can be ensured that each of the battery clusters 10 can work normally and continuously.

[0029] Furthermore, if Figure 2 As shown, the cooling module provided by the present invention may also include a current collector 30 for collecting the currents of each battery cluster 10, a fire extinguishing cabinet 40 and a fire detector 50; the current collector 30, the fire extinguishing cabinet 40 and the fire detector 50 may be directly arranged inside the housing 11 or directly arranged outside the housing 11.

[0030] See also Figure 4As shown, it can be seen that the utility model also includes a fire main engine 60, which is directly connected to the fire extinguishing cabinet 40 and the fire detector 50, so that the fire extinguishing can be immediately started when a danger is found. In addition, a master pump 70 is connected to the input main pipe 21 and the output main pipe 22 respectively, so as to control the delivery of the cooling liquid or cooling gas of the input main pipe 21 and the output main pipe 22 respectively. Furthermore, each of the input cooling pipes 211 and each of the output cooling pipes 221 has a sub-pump 71, 72 to control the input and output of each of the input cooling pipes 211 and each of the output cooling pipes 221 respectively.

[0031] Although the specific implementations of the utility model are described above, those skilled in the art should understand that the protection scope of the utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
