[0041] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0042] See also Figure 1 and Figure 2 The energy storage cabinet cooling system 100 includes a cooling device 10 and an electrical device 20. The electrical device 20 may include any device that generates heat during operation and needs to be cooled. The cooling device 10 is connected to the electrical device 20 to cool the electrical device 20. The cooling device 10 cools the electrical device 20 to ensure the working performance of the electrical device 20, improve the operating stability of the electrical device 20, and extend the service life of the electrical device 20. The electrical device 20 includes an energy storage cabinet or a battery cabinet.

[0043] For the above-mentioned cooling device 10, the cooling device 10 may include any device that can generate cooling fluid when working. The cooling fluid may be water, or a coolant, or a cooling gas, etc. The cooling device 10 is provided with a cooling port 11 and a reflux port 12. The cooling port 11 is used for the cooling fluid to flow out of the cooling device 10, and the reflux port 12 is used for the cooling fluid after the heat dissipation of the electrical device 20 to flow back into the cooling device 10 for cyclic reciprocating use.

[0044] The cooling device 10 may be a liquid cooler, a water cooler, etc. Preferably, the cooling device 10 includes a liquid cooler.

[0045] Among them, liquid cooler is a highly efficient heat dissipation technology that uses liquid (usually water or specially designed coolant) as a heat transfer medium to remove the heat generated by the heat source. Liquid coolers are widely used in occasions that require a lot of heat dissipation, such as high-performance computers, data centers, industrial equipment, medical equipment, power electronics, energy storage, automobiles and aviation fields.

[0046] One implementation of a liquid cooler is that the liquid cooler includes: a heat exchanger (not shown) for transferring the heat carried by the liquid to the air or another cooling medium; a pump (not shown) for circulating the coolant to ensure its flow throughout the system; a liquid storage tank (not shown) for storing the coolant and used as an expansion tank to accommodate the volume change of the coolant due to temperature changes. The working principle of the liquid cooler is: the coolant is pumped out of the liquid storage tank by a pump; the coolant flows through the equipment that needs to dissipate heat and absorbs heat; the coolant after absorbing the heat flows back to the heat exchanger; in the heat exchanger, the heat is transferred to the air or another cooling medium, and the coolant is therefore cooled; the cooled coolant is pumped back to the equipment that needs to dissipate heat again, and the cycle repeats.

[0047] For the above-mentioned electrical equipment 20, the electrical equipment 20 is a device that needs heat dissipation. The electrical equipment 20 includes a heat generating part 21, a first primary pipeline 22a, a second primary pipeline 22b, a secondary pipeline 23, a first two-way cut-off plug 24a and a second two-way cut-off plug 24b. One end of the first primary pipeline 22a is connected to the cooling port 11 of the cooling device 10, and the other end of the first primary pipeline 22a is connected to one end of the first two-way cut-off plug 24a; one end of the second primary pipeline 22b is connected to the return port 12 of the cooling device 10, and the other end of the second primary pipeline 22b is connected to one end of the second two-way cut-off plug 24b; one end of the secondary pipeline 23 is connected to the first primary pipeline 22a, and the other end of the secondary pipeline 23 is connected to the second primary pipeline 22b; the secondary pipeline 23 is connected to the heat generating part 21. The other end of the first two-way cut-off quick plug 24 a is used to connect to another electrical device 20 , and the other end of the second two-way cut-off quick plug 24 b is used to connect to another electrical device 20 .

[0048] It is worth noting that the electrical equipment 20 can be an energy storage cabinet or a battery cabinet. When the electrical equipment 20 is an energy storage cabinet or a battery cabinet, the heat generating component 21 includes a plurality of stacked battery packs 211, and the cooling device 10 is used to absorb the heat generated by the battery pack 211, thereby achieving cooling and heat dissipation of the battery pack 211.

[0049] The cooling fluid generated by the cooling device 10 flows into the secondary pipeline 23 through the first primary pipeline 22a, and the heat generated by the heat generating component 21 connected to the secondary pipeline 23 is dissipated to the cooling fluid in the secondary pipeline 23, and the cooling fluid absorbs the heat generated by the heat generating component 21, thereby achieving heat dissipation and cooling of the heat generating component 21.

[0050] In some embodiments, the number of the electrical equipment 20 is multiple, and the multiple electrical equipment 20 are connected in series; one end of the first primary pipeline 22a of the next electrical equipment 20 is connected to the other end of the first two-way cut-off plug 24a of the previous electrical equipment 20; one end of the second primary pipeline 22b of the next electrical equipment 20 is connected to the other end of the second two-way cut-off plug 24b of the previous electrical equipment 20. Through this configuration, the cooling fluid flowing through the previous electrical equipment 20 absorbs and takes out the heat of the heat generating part 21 of the previous electrical equipment 20, enters the secondary pipeline 23 of the next electrical equipment 20, thereby absorbing and taking out the heat of the heat generating part 21 of the next electrical equipment 20, and the cooling fluid flowing through the last electrical equipment 20 flows back into the cooling device 10 through the second primary pipeline 22b and the return port 12 of the cooling device 10, so as to realize the reciprocating circulation of the cooling fluid, and realize the reciprocating heat dissipation and cooling of the multiple electrical equipment 20. Through this configuration, one cooling device 10 can dissipate heat and cool down a plurality of electrical devices 20, thus saving costs.

[0051] It is worth noting that, in some embodiments, the other end of the first primary pipeline 22a of the last electrical device 20 may not be connected to the first two-way cut-off plug 24a, but may be connected to a stop plug 29, thereby saving costs. The other end of the second primary pipeline 22b of the last electrical device 20 may not be connected to the second two-way cut-off plug 24b, but may be connected to a stop plug 29, thereby further saving costs.

[0052] Among them, the first electrical device 20 is the electrical device 20 close to the cooling device 10, the second electrical device 20 is the electrical device 20 far away from the cooling device 10, and the last electrical device 20 is the electrical device 20 farthest from the cooling device 10. After flowing through the last electrical device 20, the cooling fluid will flow back to the cooling device 10 for reciprocating circulation.

[0053] Regarding the heat generating component 21 , the heat generating component 21 is a heat source in the electrical device 20 that specifically needs to dissipate heat.

[0054] As for the first primary pipeline 22 a mentioned above, the first primary pipeline 22 a is used for the cooling fluid generated by the operation of the cooling device 10 to flow into the secondary pipeline 23 , thereby dissipating heat and cooling the heat generating component 21 .

[0055] For the above-mentioned second primary pipeline 22b, the second primary pipeline 22b is used for the cooling fluid flowing through the secondary pipeline 23 to return from the second primary pipeline 22b to the cooling device 10 after absorbing the heat of the heat generating component 21, so as to realize the circulation of the cooling fluid, thereby achieving continuous cooling of the heat generating component 21.

[0056] As for the secondary pipeline 23 , the secondary pipeline 23 is connected to the heat generating component 21 , and the cooling fluid in the cooling device 10 flows through the secondary pipeline 23 , thereby absorbing the heat generated by the heat generating component 21 when it is working.

[0057] It is worth noting that the secondary pipeline 23 and the heat generating element 21 can be connected in various ways.

[0058] In some embodiments, one implementation method of connecting the secondary pipeline 23 to the heat generating component 21 is that one end of the secondary pipeline 23 is connected to the first primary pipeline 22a, and a tertiary pipeline 25 is arranged between one end of the secondary pipeline 23 and the other end of the secondary pipeline 23, one end of the tertiary pipeline 25 is connected to the secondary pipeline 23, and the other end of the tertiary pipeline 25 is arranged inside the heat generating component 21.

[0059] In some embodiments, the heat generating part 21 includes a plurality of stacked battery packs 211, the secondary pipelines 23 are distributed on both sides of the plurality of stacked battery packs 211, the number of the tertiary pipelines 25 is multiple, the number of the tertiary pipelines 25 is twice the number of the battery packs 211, and the plurality of tertiary pipelines 25 are distributed on both sides of the plurality of stacked battery packs 211, and one battery pack 211 corresponds to two tertiary pipelines 25. Through the above arrangement, efficient heat dissipation of the heat generating part 21 can be achieved.

[0060] In some embodiments, one way to connect the secondary pipeline 23 to the heat generating element 21 is that one end of the secondary pipeline 23 is connected to the first primary pipeline 22a, and the other end of the secondary pipeline 23 is spirally arranged around the heat generating element 21 and then connected to the second primary pipeline 22b.

[0061] It is worth noting that, in some embodiments, one end of the secondary pipeline 23 is arranged close to the cooling device 10, and the other end of the secondary pipeline 23 is arranged away from the cooling device 10. Through this arrangement, the distance between the cooling device 10 and one end of the secondary pipeline 23 is shortened, so that the cooling fluid generated by the cooling device 10 can enter the secondary pipeline 23, thereby dissipating the heat of the heat generating part 21, thereby improving the heat dissipation efficiency of the cooling fluid generated by the cooling device 10 on the heat generating part 21.

[0062] It is worth noting that in some embodiments, please continue to refer to Figure 1 and Figure 2, one end of the secondary pipeline 23 is also connected to the first primary pipeline 22a through the first two-way stop valve 26a, and the other end of the secondary pipeline 23 is connected to the second primary pipeline 22b through the second two-way stop valve 26b. Specifically, the first two-way stop valve 26a is arranged on the first primary pipeline 22a, and one end of the secondary pipeline 23 is connected to the first two-way stop valve 26a, so that one end of the secondary pipeline 23 is connected to the first primary pipeline 22a; the second two-way stop valve 26b is arranged on the second primary pipeline 22b, and the other end of the secondary pipeline 23 is connected to the second two-way stop valve 26b, so that the other end of the secondary pipeline 23 is connected to the second primary pipeline 22b. Through this arrangement, even when there is cooling fluid in the first primary pipeline 22a and the second primary pipeline 22b, the connection between the secondary pipeline 23 and the first primary pipeline 22a and the second primary pipeline 22b is released. Due to the shut-off effect of the first two-way stop valve 26a and the second two-way stop valve 26b, there is no need to drain the cooling fluid in the first primary pipeline 22a and the second primary pipeline 22b. Therefore, when a plurality of the electrical devices 20 are quickly connected through the first two-way shut-off quick plug 24a and the second two-way shut-off quick plug 24b, the secondary pipeline 23 and the heat generating component 21 can be removed, thereby facilitating the connection of a plurality of the electrical devices 20.

[0063] The first two-way stop valve 26a and the second two-way stop valve 26b are both two-way stop valves, and the first two-way stop valve 26a and the second two-way stop valve 26b may have the same structure.

[0064] A two-way stop valve is a valve that can control the flow of fluid in both directions. It has the ability to cut off or regulate the flow of fluid in either direction, which makes the two-way stop valve very useful when the flow direction needs to be switched frequently or in a two-way flow system.

[0065] It is worth noting that in some embodiments, the first two-way stop valve 26a and the second two-way stop valve 26b mentioned above may not be used, and the function of dissipating heat for the electrical equipment 20 in the embodiment of the present application can also be realized, the function of dissipating heat for multiple electrical equipment 20 by one cooling device 10 can be realized, and the function of quickly disassembling and assembling multiple electrical equipment 20 can be realized.

[0066] It is worth noting that, in some embodiments, two ball valves may be used to replace the first two-way stop valve 26a and the second two-way stop valve 26b. A ball valve is a widely used type of valve, and its main features are simple structure, small size, light weight, and easy operation and maintenance. A ball valve controls the flow of a fluid through a sphere and channel holes thereon. When the sphere rotates, these channel holes are aligned or staggered with the inlet and outlet of the valve, thereby realizing opening or closing the flow of the fluid.

[0067] Regarding the first two-way quick cutoff plug 24a and the second two-way quick cutoff plug 24b, the first two-way quick cutoff plug 24a and the second two-way quick cutoff plug 24b are both two-way quick cutoff plugs, and the first two-way quick cutoff plug 24a and the second two-way quick cutoff plug 24b may have the same structure.

[0068] Among them, the two-way cut-off quick plug is a valve assembly that can be quickly connected and disconnected, which can prevent the flow of fluid (such as cooling fluid) in both directions. This design is used in applications that require frequent connection and disconnection, such as in laboratories, medical equipment, water treatment systems, pneumatic control systems, and other industrial fields that require quick replacement or movement of fluid connections. The working principle of the two-way cut-off quick plug usually involves a plug with a built-in valve. When the plug is inserted into the socket, the valve opens to allow fluid flow; when the plug is pulled out, the valve closes to prevent fluid flow. This mechanism ensures the controllability and safety of fluid transmission.

[0069] In the embodiment of the present application, the first two-way cut-off quick plug 24a and the second two-way cut-off quick plug 24b are both the above-mentioned two-way cut-off quick plugs, and the first two-way cut-off quick plug 24a and the second two-way cut-off quick plug 24b are both used to prevent the flow of cooling fluid. When the number of the electrical equipment 20 is multiple, when the valve of the first two-way cut-off quick plug 24a and the valve of the second two-way cut-off quick plug 24b are both opened, the cooling fluid can flow from the previous electrical equipment 20 to the next electrical equipment 20. When the valve of the first two-way cut-off quick plug 24a and the valve of the second two-way cut-off quick plug 24b are both closed, the cooling fluid is prevented from flowing, and any two adjacent electrical equipment 20 are separated, so that the electrical equipment 20 can be carried separately, saving labor and trouble. In addition, when multiple electrical devices 20 need to be separated, the fluid is blocked by the first two-way shut-off quick plug 24a and the second two-way shut-off quick plug 24b, and the cooling fluid in the first primary pipeline 22a, the second primary pipeline 22b, and the secondary pipeline 23 can be transported together without the need to configure or find a plug for shutting off the cooling fluid, or to drain the cooling fluid in the first primary pipeline 22a, the second primary pipeline 22b, and the secondary pipeline 23, which saves time and effort and provides a good user experience.

[0070] It is worth noting that, in some embodiments, see Figure 3 and Figure 4 The electrical device 20 further includes a first connecting tube 27a and a second connecting tube 27b. One end of the first connecting tube 27a is connected to the other end of the first two-way stop plug 24a; one end of the second connecting tube 27b is connected to the other end of the second two-way stop plug 24b. The other end of the first connecting tube 27a is used to connect to another electrical device 20, and the other end of the second connecting tube 27b is used to connect to another electrical device 20. In some embodiments, the first connecting tube 27a and the second connecting tube 27b are both hoses. By setting the first connecting tube 27a and the second connecting tube 27b, when assembling the two electrical devices 20, the tolerance of the two electrical devices 20 can be adjusted by the length of the first connecting tube 27a and the second connecting tube 27b, thereby facilitating the assembly of the two electrical devices 20.

[0071] It is worth noting that, in some embodiments, see Figure 5 and Figure 6 In addition to the first connecting tube 27a and the second connecting tube 27b, the electrical equipment 20 also includes a third two-way quick-cut plug 24c and a fourth two-way quick-cut plug 24d. One end of the first connecting tube 27a is connected to the other end of the first two-way quick-cut plug 24a, and the other end of the first connecting tube 27a is connected to one end of the third two-way quick-cut plug 24c; one end of the second connecting tube 27b is connected to the other end of the second two-way quick-cut plug 24b, and the other end of the second connecting tube 27b is connected to one end of the fourth two-way quick-cut plug 24d. The other end of the third two-way quick-cut plug 24c is used to connect to another electrical equipment 20, and the other end of the fourth two-way quick-cut plug 24d is used to connect to another electrical equipment 20.

[0072] Among them, the third two-way cut-off quick plug 24c and the fourth two-way cut-off quick plug 24d are both two-way cut-off quick plugs. The third two-way cut-off quick plug 24c and the fourth two-way cut-off quick plug 24d can have the same structure, and can adopt the two-way cut-off quick plug applied to the first two-way cut-off quick plug 24a and the second two-way cut-off quick plug 24b introduced above.

[0073] Through the above arrangement, the first primary pipelines 22a of any two adjacent electrical devices 20 are connected to the first connecting pipe 27a through two two-way cut-off plugs (the first two-way cut-off plug 24a and the third two-way cut-off plug 24c), and the second primary pipelines 22b of any two adjacent electrical devices 20 are connected to the second connecting pipe 27b through two two-way cut-off plugs (the second two-way cut-off plug 24b and the fourth two-way cut-off plug 24d). When the two adjacent electrical devices 20 are separated, the first connecting pipe 27a and the second connecting pipe 27b are not connected to any electrical device 20, so that the number of components connected to any electrical device 20 is small, and the electrical device 20 is easy to carry and install.

[0074] More importantly, in some embodiments, the first connecting tube 27a and the second connecting tube 27b are both hoses. Through the arrangement of the first connecting tube 27a and the second connecting tube 27b, when assembling two electrical devices 20, the tolerance matching of the two electrical devices 20 can be adjusted by the length of the first connecting tube 27a and the second connecting tube 27b, thereby facilitating the assembly of the two electrical devices 20.

[0075] It is worth noting that, in some embodiments, in order to achieve waterproofing when assembling two electrical devices 20, please refer to Figure 7 and Figure 8 , two wall-penetrating members 28 are provided on the electrical equipment 20. One end of the first connecting pipe 27a is connected to the other end of the first two-way cut-off quick plug 24a, and the other end of the first connecting pipe 27a passes through one of the wall-penetrating members 28 and is connected to one end of the third two-way cut-off quick plug 24c; one end of the second connecting pipe 27b is connected to the other end of the second two-way cut-off quick plug 24b, and the other end of the second connecting pipe 27b passes through another of the wall-penetrating members 28 and is connected to one end of the fourth two-way cut-off quick plug 24d. The other end of the third two-way cut-off quick plug 24c is used to connect to another electrical equipment 20, and the other end of the fourth two-way cut-off quick plug 24d is used to connect to another electrical equipment 20.

[0076] In some embodiments, see Fig. 9The wall penetration member 28 includes a shaft portion 281, a first abutting member 282, a first sealing member 283, a second sealing member 284, and a second abutting member 285. The shaft portion 281 is provided with a through hole 2811, and the through hole 2811 is used for the first connecting tube 27a or the second connecting tube 27b to pass through; the first abutting member 282, the first sealing member 283, the second sealing member 284, and the second abutting member 285 are sequentially arranged around the shaft portion 281, and the first sealing member 283 and the second sealing member 284 are arranged at intervals; the first abutting member 282 is screwed to the shaft portion 281, and the second abutting member 285 is screwed to the shaft portion 281. When two electrical devices 20 are connected, the shaft 281 passes through the two heat generating parts 21, and the first sealing part 283, the outer shell of the heat generating part 21 of one of the electrical devices 20, the outer shell of the heat generating part 21 of the other electrical device 20 and the second sealing part 284 are clamped by the first abutting part 282 and the second abutting part 285. The first sealing part 283 abuts against the inner wall of the heat generating part 21 of one of the electrical devices 20, and the second sealing part 284 abuts against the inner wall of the heat generating part 21 of the other electrical device 20, so that the first sealing part 283 can seal and waterproof one of the heat generating parts 21, and the second sealing part 284 can seal and waterproof the other heat generating part 21, so as to protect the internal equipment of the two heat generating parts 21 and extend the service life of the heat generating parts 21.

[0077] It is worth noting that, in some embodiments, the first abutment member 282 is disposed at one end of the shaft portion 281 , and the first abutment member 282 and the shaft portion 281 are integrally formed.

[0078] It is worth noting that, in some embodiments, the first sealing member 283 and the second sealing member 284 are both rubber rings.

[0079] In the embodiment of the present application, the cooling device 10 will generate a cooling fluid when working. The cooling fluid flows from the cooling port 11 of the cooling device 10 into the secondary pipeline 23 through the first primary pipeline 22a. The heat generated by the heat generating part 21 connected to the secondary pipeline 23 is dissipated to the cooling fluid in the secondary pipeline 23, thereby achieving heat dissipation for the heat generating part 21.

[0080] In addition, when there are multiple electrical devices 20, the cooling fluid flowing out from the secondary pipeline 23 of the previous electrical device 20 flows into the secondary pipeline 23 of the next electrical device 20, thereby dissipating the heat generating part 21 of the next electrical device 20, thereby achieving heat dissipation of the heat generating parts 21 of multiple electrical devices 20.

[0081] In addition, since the first primary pipeline 22a is connected to the first two-way cut-off plug 24a, and the second primary pipeline 22b is connected to the second two-way cut-off plug 24b, the capacity of the electrical device 20 can be expanded through the two two-way cut-off plugs, and quick connection and disassembly with another electrical device 20 can be achieved, so that one cooling device 10 can cool multiple electrical devices 20, saving costs. In other words, when the electrical device 20 includes an energy storage cabinet or a battery cabinet, the energy storage cabinet cooling system 100 provided by the present application does not need to be equipped with a cooling device 10 for each electrical device 20, and can achieve cooling and cooling of multiple energy storage cabinets or battery cabinets, so that in the scenario where multiple energy storage cabinets or battery cabinets need to be used in combination, the equipment cost and space can be greatly saved.

[0082] In addition, since the first two-way cut-off quick plug 24a and the second two-way cut-off quick plug 24b are provided, when there are multiple electrical devices 20 in the energy storage cabinet cooling system 100, when the energy storage cabinet cooling system 100 is transported, the multiple electrical devices 20 can be separated by the first two-way cut-off quick plug 24a and the second two-way cut-off quick plug 24b, so that the energy storage cabinet cooling system 100 is convenient to transport.

[0083] In addition, when the energy storage cabinet cooling system 100 is transported, due to the shutoff effect of the first two-way shutoff quick plug 24a and the second two-way shutoff quick plug 24b, the cooling fluid in the first primary pipeline 22a, the second primary pipeline 22b, and the secondary pipeline 23 can be transported together without the need for additional plugs to block the cooling fluid, and without the need to drain the cooling fluid in the first primary pipeline 22a, the second primary pipeline 22b, and the secondary pipeline 23, which saves time and trouble and provides a good user experience.

[0084] The embodiment of the present application also provides an embodiment of an energy storage product, and the energy storage product includes the energy storage cabinet cooling system 100. For the specific structure and function of the energy storage cabinet cooling system 100, please refer to the above embodiment, which will not be repeated here. The electrical equipment 20 in the energy storage cabinet cooling system 100 includes an energy storage cabinet or a battery cabinet. When the number of electrical equipment 20 in the energy storage cabinet cooling system 100 is multiple, the multiple electrical equipment 20 may include one energy storage cabinet and multiple battery cabinets, or may include multiple energy storage cabinets, or may include multiple battery cabinets, or may include multiple energy storage cabinets and multiple battery cabinets. The specific implementation form of the energy storage product can be reasonably set according to actual needs.

[0085] It is worth noting that, in some embodiments, see Fig.10The energy storage product includes an energy storage cabinet 300 and multiple battery cabinets 200, and the number of the electrical equipment 20 is multiple. The cooling device 10 and one electrical equipment 20 can be regarded as one energy storage cabinet 300, and the other electrical equipment 20 can be regarded as battery cabinets 200, so as to realize the series connection of one energy storage cabinet 300 and multiple battery cabinets 200, so that while expanding the capacity of the energy storage cabinet 300, multiple battery cabinets 200 can use the cooling equipment of the energy storage cabinet 300 for cooling, saving costs.
