Description

Technical Field

[0001] The invention belongs to the technical field of energy storage cabinets, and in particular relates to a vertical energy storage cabinet. Background Art

[0002] With the rapid development of the energy storage industry, the market has higher and higher requirements for energy storage systems. At present, energy storage systems generally have problems such as large battery capacity and power, internal battery heat generation and uneven temperature distribution. Therefore, higher requirements are placed on the heat dissipation of energy storage systems.

[0003] For example, CN112968239A discloses an energy storage battery cabinet, which includes a cabinet body and a battery room and an electrical room located inside the cabinet body, wherein a temperature control device is provided in the electrical room and a pipe system is provided in the battery room; the temperature control device has a circulating fluid inside, and the circulating fluid can be used to control the temperature of the batteries in the battery cabinet. The pipe system includes a water inlet pipe and a water outlet pipe, wherein one end of the water inlet pipe is connected to the water outlet of the temperature control device, and the other end of the water inlet pipe is used to connect to the water inlet of the battery pack in the battery room, and one end of the water outlet pipe is connected to the water inlet of the temperature control device, and the other end of the water outlet pipe is used to connect to the water outlet of the battery pack. For another example, CN217881651 U discloses an energy storage cabinet, including a battery compartment for arranging a battery cluster, and the energy storage cabinet also includes: a temperature regulation system, the temperature regulation system is used to regulate the heat dissipation of all battery clusters in the battery compartment; wherein the temperature regulation system includes: a first box body, used to store coolant; a liquid supply pipeline, arranged between the battery cluster and the first box body, the liquid supply pipeline is provided with a plurality of heat dissipation parts, each heat dissipation part is respectively close to any battery cluster, and the coolant exchanges heat with the battery cluster when flowing through the heat dissipation part; a liquid return pipeline, one end of which is connected to the end of the liquid supply pipeline, and the other end is connected to the first box body, and the coolant circulates through the liquid supply pipeline and the liquid return pipeline. When the energy storage battery cabinet disclosed above is in use, the coolant is circulated sequentially along the cooling pipeline. This method causes the temperature of the coolant to continue to rise as the coolant circulates in the cooling pipeline. This method results in a good cooling effect on the battery pack modules located at the water inlet section of the cooling pipeline, and a poor cooling effect on the battery pack modules located at the water outlet section of the cooling pipeline. Overall, the cooling effect of the battery pack modules is different depending on the flow direction of the coolant in the cooling pipeline, which can easily cause different degrees of life decay of multiple battery pack modules in the energy storage cabinet over time. Summary of the invention

[0004] The object of the present invention is to provide a vertical energy storage cabinet, which solves the problem of different cooling effects of multiple battery pack modules proposed in the prior art by controlling the forward and reverse flow of coolant along a cooling system composed of multiple cooling mechanisms.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 As shown, the present invention is a vertical energy storage cabinet, which includes a cabinet body 8, in which five battery pack modules 80 are arranged in sequence from top to bottom; and cooling mechanism 1 1, cooling mechanism 2 2, cooling mechanism 3 3, cooling mechanism 4 4 and cooling mechanism 5 5 are respectively arranged on the five battery pack modules 80 arranged from top to bottom; and a liquid storage tank 6 and a liquid return tank 7 are respectively arranged on the top and bottom of the cabinet body 8, and a transfer mechanism for sending the coolant in the liquid return tank 7 into the liquid storage tank 6 is provided, and the transfer mechanism includes a cooling tank 70 arranged on the top of the cabinet body 8; and the cooling mechanism 1 1, cooling mechanism 2 2, cooling mechanism 3 3, cooling mechanism 4 4 and cooling mechanism 5 5 are connected in series in sequence to form a cooling system.

[0035] Furthermore, when in use, the coolant in the liquid storage tank 6 is controlled to enter the cooling mechanism 1, and then flows through the cooling mechanism 2 2, the cooling mechanism 3 3, the cooling mechanism 4 4 and the cooling mechanism 5 5 in sequence before entering the liquid return tank 7; after a period of time, the coolant in the liquid storage tank 6 is controlled to enter the cooling mechanism 5 5, and then flows through the cooling mechanism 4 4, the cooling mechanism 3 3, the cooling mechanism 2 2 and the cooling mechanism 1 1 in sequence before entering the liquid return tank 7. By switching between the forward and reverse flows, it is convenient to maintain the five battery pack modules 80 to obtain substantially the same cooling effect when in use.

[0036] Of course, we know that Figure 2 In order to facilitate the switching of the coolant's inward and reverse flows in the cooling system, in the present invention, the end of the cooling mechanism 1 away from the cooling mechanism 2 2 is connected to the water inlet pipe A61 and the water return pipe A12 respectively; the end of the cooling mechanism 5 away from the cooling mechanism 4 4 is connected to the water inlet pipe B63 and the water return pipe B52 respectively; the water inlet pipe B63 and the water inlet pipe A61 are both connected to the bottom side of the liquid storage tank 6; the water return pipe A12 and the water return pipe B52 are both connected to the top of the liquid return tank 7; the water inlet pipe A61 and the water inlet pipe B63 are respectively provided with an electric flow valve A62 and an electric flow valve B64; the water return pipe A12 and the water return pipe B52 are respectively provided with an electromagnetic valve A13 and an electromagnetic valve B53, and the electric flow valve A62, the electric flow valve B64, the electromagnetic valve A13 and the electromagnetic valve B53 are all connected to a controller.

[0037] Furthermore, based on the above, when in use, the present invention controls the switches of the electric flow valve A62, the electric flow valve B64, the solenoid valve A13, and the solenoid valve B53 to switch the coolant flow in the cooling system accordingly.

[0038] That is, the cooling control system composed of the controller, the electric flow valve A62, the electric flow valve B64, the solenoid valve A13 and the solenoid valve B53 includes a first operating state and a second operating state of alternating operation during operation.

[0039] Specifically, in the first operating state, the electric flow valve A62 and the solenoid valve B53 are opened, and the electric flow valve B64 and the solenoid valve A13 are closed, and the coolant in the liquid storage tank 6 is controlled to flow through the cooling mechanism 1 1, the cooling mechanism 2 2, the cooling mechanism 3 3, the cooling mechanism 4 4 and the cooling mechanism 5 5 in sequence at a flow rate of the set value V1;

[0040] In the second operating state, the electric flow valve B64 and the solenoid valve A13 are opened, and the electric flow valve A62 and the solenoid valve B53 are closed, and the coolant in the liquid storage tank 6 is controlled to flow through the cooling mechanism five 5, the cooling mechanism four 4, the cooling mechanism three 3, the cooling mechanism two 2 and the cooling mechanism one 1 in sequence at a flow rate of the set value V1.

[0041] Likewise, it is understandable that Figure 2 In the actual operation process, it is necessary to detect whether the five battery pack modules 80 in the cabinet 8 are operating abnormally. Based on this, temperature sensor 1 11, temperature sensor 2 2, temperature sensor 3 3, temperature sensor 4 4 and temperature sensor 5 5 are respectively arranged at the middle position of cooling mechanism 1 1, cooling mechanism 2 2, cooling mechanism 3 3, cooling mechanism 4 4 and cooling mechanism 5 5; and temperature sensor 1 11, temperature sensor 2 21, temperature sensor 3 31, temperature sensor 4 41 and temperature sensor 5 51 are all connected to the controller.

[0042] Furthermore, based on the combination of the temperature sensor, the provided cooling control system includes a battery pack module 80 operating status detection mode and a battery pack module 80 cooling operating mode; and the battery pack module 80 operating status detection mode and the battery pack module 80 cooling operating mode operate alternately.

[0043] Specifically, the cooling operation mode of the battery pack module 80 mentioned includes a first operation state and a second operation state that operate alternately.

[0044] Specifically, the battery pack module 80 operating status detection modes mentioned include:

[0045] Step 1, open the electric flow valve A62, control the coolant in the liquid storage tank 6 to flow through the cooling mechanism 1 1, the cooling mechanism 2 2, the cooling mechanism 3 3, the cooling mechanism 4 4 and the cooling mechanism 5 5 in sequence at a flow rate of the set value V1;

[0046] Step 2, the temperature T1 in the cooling mechanism 1 is detected by the temperature sensor 11. When T1 is higher than the set value T10, it indicates that the top battery pack module 80 is overheated. On the contrary, when T1 is lower than the set value T10, it indicates that the top battery pack module 80 is operating normally.

[0047] Step 3, adjust the opening of the electric flow valve A62 until the temperature sensor 11 detects that the temperature T1 in the cooling mechanism 1 meets the set value T10, and after S time, the temperature sensor 21 detects the temperature T2 in the cooling mechanism 2; when T2 is higher than the set value T20, it indicates that the sub-top battery pack module 80 is overheated at this time, otherwise T2 is lower than the set value T20, indicating that the sub-top battery pack module 80 is operating normally at this time;

[0048] Step 4: Repeat step 3 to check whether the remaining three battery pack modules 80 are operating normally.

[0049] In a possible implementation, when the temperature sensor 1 11 is running in the first operating state, the temperature detected by the temperature sensor 1 is 28°C; when the temperature sensor 5 51 is running in the second operating state, the temperature detected by the temperature sensor 5 is 30°C; at this time, it is preliminarily determined that there is overheating at a battery pack module 80. When the temperature detected by the temperature sensor 1 11 is 29.7°C; when the temperature detected by the temperature sensor 5 51 is 28.2°C in the second operating state, it is preliminarily determined that there is overheating at a battery pack module 80.

[0050] At the same time, when it is determined that a battery pack module 80 is overheated in the first operating state or the second operating state, the control system switches from the battery pack module 80 cooling operating mode to the battery pack module 80 operating state detection mode.

[0051] It can be understood that the cooling tank 70 provided by the present invention is provided with a temperature sensor A71, a refrigeration module 73, and a liquid level sensor 72 connected to the controller; and the cooling tank 70 is higher than the top of the liquid storage tank 6, and the bottom of the cooling tank 70 is connected to the liquid storage tank 6, and the return liquid tank 7 is provided with a pressure pump 74 for delivering the coolant in the return liquid tank 7 into the cooling tank 70. By utilizing the settings of the temperature sensor A71, the refrigeration module 73, and the liquid level sensor 72, the pressure pump 74 is first used to deliver the coolant in the return liquid tank 7 into the cooling tank 70 until the liquid level sensor 72 detects that the liquid level meets the set value. At this time, the refrigeration module 73 is started to cool the coolant in the cooling tank 70, and it is discharged into the liquid storage tank 6 after cooling to the set temperature.

[0052] It can be known that the cooling mechanism 1, cooling mechanism 2, cooling mechanism 3, cooling mechanism 4, and cooling mechanism 5 provided by the present invention have the same structure; they all include a first cooling module arranged on the top of the battery pack module 80, and a second cooling module arranged at the bottom; when in use, the first cooling module and the second cooling module can be arranged in series or in parallel according to installation requirements; at the same time, the first cooling module and the second cooling module have the same structure.

[0053] Specifically, the first cooling module and the second cooling module mentioned in the present invention both include a plurality of cooling tubes 10; when the plurality of cooling tubes 10 are connected in series, it is easy to cause different cooling effects on various parts of the battery pack module 80, and when the cooling tubes 10 are connected in parallel, the same cooling effect is achieved on any part of the battery pack module 80; similarly, when the first cooling module and the second cooling module are connected in series, different cooling effects are achieved on the upper and lower sides of the battery pack module 80, and when the first cooling module and the second cooling module are connected in parallel, the same cooling effect is achieved on the upper and lower sides of the battery pack module 80.

[0054] More specifically, Figure 4The cooling tube 10 mentioned above includes a first contact surface 101, a second contact surface 102, a third contact surface 103 and a fourth contact surface 104 that are in contact with the battery pack module 80; the widths of the first contact surface 101, the second contact surface 102, the third contact surface 103 and the fourth contact surface 104 decrease successively; and the first contact surface 101 and the third contact surface 103 are parallel, and the second contact surface 102 and the fourth contact surface 104 are parallel. By utilizing the different widths of the four contact surfaces, the contact area between the cooling tube 10 and the battery pack module 80 can be adjusted according to needs during installation, thereby controlling the cooling effect of the cooling tube 10 on the battery pack module 80 to adjust.

[0055] In view of the setting of the flow direction of the coolant in the present invention, when the cooling mechanism 3 3 in the middle position cools the corresponding battery pack module 80, the temperature of the coolant flowing through the battery pack module 80 is high, and at this time, it is necessary to increase the contact area between the cooling mechanism 3 3 and the battery pack module 80. That is, in practice, the cooling tube 10 in the cooling mechanism 1 1, the cooling mechanism 2 2, the cooling mechanism 3 3, the cooling mechanism 4 4 and the cooling mechanism 5 5 respectively controls its first contact surface 101, the second contact surface 102, the third contact surface 103, the second contact surface 102 and the first contact surface 101 to contact the battery pack module 80; or controls the first contact surface 101, the second contact surface 102, the fourth contact surface 104, the second contact surface 102 and the first contact surface 101 of the cooling tube 10 to contact the battery pack module 80.

[0056] Of course, in order to facilitate the fixing and adjustment of the cooling pipe 10 in practice, the present invention provides a fixing structure 9 for fixing the cooling pipe 10 at the top and bottom of the battery pack module 80, so as to adjust any contact surface of the cooling pipe 10 to contact the battery pack module 80 as required during use; Figure 3 The fixing structure 9 includes a first fixing module 90 and a second fixing module 91 which are arranged in cooperation; and a third fixing module 92 for fixing the first fixing module 90 and the second fixing module 91 is arranged on the battery pack module 80; the third fixing module 92 includes an L-shaped block 921, and a locking bolt A921 is arranged on the L-shaped block 921; the second fixing module 91 includes a vertical rod B911, and a locking bolt A921 is arranged at the bottom end of the vertical rod B911 to be inserted between the L-shaped block and the battery pack module 80. Pin B912, the top of the vertical rod B911 is provided with a socket 913 for inserting the plug rod 903, the socket 913 is provided with a locking bolt B914 whose end rests on the plug rod 903, and a locking bolt C915 whose end rests on the battery pack module 80; the first fixing module 90 includes a vertical rod A901, the bottom end of the vertical rod A901 is provided with a pin A902 inserted between the L-shaped block and the battery pack module 80, and the top of the vertical rod A901 is provided with the plug rod 903.
