Description

Technical Field

[0001] This utility model relates to the technical field of cooling pipeline systems, and in particular to an energy storage cooling pipeline system. Background Technology

[0002] Energy storage units generate a lot of heat during operation, requiring constant cooling to prevent damage.

[0003] The existing cooling method involves a pipeline system in which coolant flows through several energy storage units to cool them.

[0004] Several energy storage units are placed in the existing space. The temperature of each energy storage unit is greatly affected by the space and location. Some energy storage units have very high temperatures. The cooling effect of the coolant flowing once in the pipeline system is not obvious for the overheated energy storage units, resulting in a small temperature drop per unit time and failing to achieve a rapid cooling effect. In addition, the inability to cool down quickly can easily lead to a reduction in the lifespan of this energy storage unit. Utility Model Content

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] Reference Figure 1 The present invention discloses an energy storage cooling pipeline system, comprising a pipeline system body 1 and several energy storage units 2. In this embodiment, the number of energy storage units 2 is four.

[0036] The main body of the piping system 1 includes a liquid cooling unit 11, a first cooling pipe circuit 3, a second cooling pipe circuit 4, a third cooling pipe circuit 5, and a PLC controller 6.

[0037] Each of the energy storage units 2 is equipped with a first temperature sensor 21 and a second temperature sensor 22. The PLC controller 6 is electrically connected to the four first temperature sensors 21 and the four second temperature sensors 22.

[0038] Based on the temperature of the corresponding energy storage unit 2 sensed by the first temperature sensor 21 and the second temperature sensor 22, the first cooling pipe circuit 3 is opened, or the first cooling pipe circuit 3 and the second cooling pipe circuit 4 are opened simultaneously, or the first cooling pipe circuit 3, the second cooling pipe circuit 4 and the third cooling pipe circuit 5 are opened simultaneously.

[0039] Reference Figure 2 The first cooling pipe circuit 3 includes a first pipe 31. The first pipe 31 is arranged around the four energy storage units 2. The first and last ends of the first pipe 31 are connected to the output port and input port of the liquid cooling unit 11, respectively. The flow direction of the coolant in the first pipe 31 is as follows: Figure 2 As shown.

[0040] Figure 2 The first pipeline 31 is relatively close to the energy storage unit 2; it is shown in the diagram to clearly illustrate its location. The first pipeline 31 forms a spiral upward structure around several energy storage units 2, and its placement route creates a placement space 32. All energy storage units 2 are located within the placement space 32.

[0041] After the coolant is cooled by the liquid cooling unit 11, it flows along the first pipeline 31, absorbing the temperature of the four energy storage units 2, thereby reducing the temperature of the energy storage units 2 themselves.

[0042] Reference Figure 3 The second cooling pipe circuit 4 includes several second pipes 41. In this embodiment, there are four second pipes 41. The number of second pipes 41 is equal to the number of energy storage units 2. One end of each second pipe 41 is connected to a first pipe 31. The inlet end of the second pipe 41 is close to the inlet end of the first pipe 31.

[0043] Each second pipe 41 has a spiral-shaped upward structure surrounding its corresponding energy storage unit 2. The other end of each second pipe 41 is connected to a connecting pipe 42, one end of which is connected to the first pipe 31. A first solenoid valve 43 is installed on each second pipe 41 near its connection to the first pipe 31. The first solenoid valve 43 is electrically connected to a corresponding first temperature sensor 21. The PLC controller 6 is electrically connected to several of the first solenoid valves 43.

[0044] When the cooling operation begins, the first temperature sensor 21 detects that the temperature exceeds the preset value and sends an electrical signal to the PLC controller 6. The PLC controller 6 then opens several first solenoid valves 43. The coolant in the first pipe 31 is divided, with some still flowing through the first pipe 31 and the other four parts flowing through their respective second pipes 41, increasing the surface area through which the coolant flows and improving the cooling capacity.

[0045] The coolant flowing through the four second pipes 41 all flows to the connecting pipe 42, and finally flows to the first pipe 31 through the connecting pipe 42.

[0046] A first check valve 44 is installed near the connection point between the connecting pipe 42 and the first pipe 31. Finally, the liquid in the four second pipes 41 merges with the coolant in the first pipe 31 and re-enters the liquid cooling unit 11.

[0047] Reference Figure 4 The third cooling pipe circuit 5 includes several third pipes 51, the number of which is equal to the number of energy storage units 2.

[0048] One end of each of the third pipes 51 is connected to the connecting pipe 42. The interior of each third pipe 51 is connected to the interior of the connecting pipe 42. The third pipes 51 rise in a spiral structure around the corresponding energy storage unit 2, and the third pipes 51 and the corresponding second pipes 41 rise in an intersecting spiral. The other end of each third pipe 51 is connected to the connecting pipe 42. A second solenoid valve 52 is provided at the inlet end of the third pipe 51, and a second check valve 53 is provided at the outlet end of the third pipe 51.

[0049] The second solenoid valve 52 is electrically connected to the corresponding second temperature sensor 22. The PLC controller 6 is electrically connected to the four second solenoid valves 52.

[0050] The second temperature sensor 22 detects the temperature of the corresponding energy storage unit 2. When the temperature exceeds the preset value of the second temperature sensor 22. It should be noted that the preset value of the first temperature sensor 21 is much smaller than the preset value of the second temperature sensor 22.

[0051] The second temperature sensor 22 sends an electrical signal to the PLC controller 6, and the PLC controller 6 opens the corresponding second solenoid valve 52.

[0052] Here's a general explanation: when a first temperature sensor 21 or a second temperature sensor detects that the temperature exceeds a preset value, the PLC controller 6 opens the corresponding first solenoid valve 43 or second solenoid valve 52.

[0053] Some of the coolant enters the corresponding third pipe 51 from the connecting pipe 42 and moves along the third pipe 51 to further cool the corresponding energy storage unit 2.

[0054] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
