Description

Technical Field

[0001] The utility model relates to the technical field of energy storage cabinets, in particular to an energy storage liquid cooling unit. Background Art

[0002] Energy storage cabinets are devices used to store electrical energy and are commonly used in homes, commercial buildings, industrial facilities, large power systems and other application scenarios.

[0003] The energy storage cabinet includes components such as battery packs, inverters, and energy management systems, which have the function of flexibly storing and using electrical energy. These components will generate a lot of heat during operation. If the heat accumulates in the energy storage cabinet, it may cause the performance of the components to decline or even be damaged. There may also be safety hazards. Therefore, a cooling device is required to cool the components that need to be cooled, so that the heat can be discharged to the outside in time to avoid heat accumulation in the energy storage cabinet.

[0004] The existing cooling device is usually a water-cooled unit. The liquid cooling device includes a water pump, which is connected to a liquid inlet pipe and a liquid outlet pipe. The coolant enters the energy storage cabinet through the liquid inlet pipe and cools the components to be cooled. The coolant carrying heat enters the liquid outlet pipe under the action of the water pump and is discharged to the outside to achieve cooling inside the energy storage cabinet. During the operation of the water-cooled unit, the water pump, as a vulnerable component, often needs maintenance and replacement. Every time the water pump is replaced, the coolant of the entire system needs to be drained, and the water needs to be refilled after the water pump is replaced. There are problems such as waste of coolant, cumbersome procedures, and low maintenance efficiency. When the water pump is replaced, the coolant may leak into the cabinet. Utility Model Content

[0028] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] See also Figure 1-Figure 3 The utility model provides an energy storage liquid cooling unit, including a cabinet 1, a water pump 2 and a conveying component 3. The cabinet 1 is used to place the component to be cooled. The water pump 2 is arranged inside the cabinet 1, and the water pump 2 is connected to a liquid inlet pipe 21 and a liquid outlet pipe 22. At least part of the liquid inlet pipe 21 is arranged inside the cabinet 1, and is used to cool the component to be cooled. The liquid inlet pipe 21 is provided with a liquid inlet valve 211. The output end of the liquid inlet valve 211 to the output end of the liquid inlet pipe 21 forms a first liquid inlet section 212 of the liquid inlet pipe 21, and the input end of the liquid inlet pipe 21 to the input end of the liquid inlet valve 211 forms a second liquid inlet section 213 of the liquid inlet pipe 21. The liquid outlet pipe 22 is provided with a liquid outlet valve 221. The input end of the liquid outlet pipe 22 to the input end of the liquid outlet valve 221 forms a first liquid outlet section 222 of the liquid outlet pipe 22, and the output end of the liquid outlet valve 221 to the output end of the liquid outlet pipe 22 forms a second liquid outlet section 223 of the liquid outlet pipe 22.

[0030] Among them, the water pump 2 is detachably arranged on the bottom surface of the cabinet 1 through an installation base (not shown in the figure), the input end of the liquid inlet pipe 21 is connected to the side wall of the cabinet 1, the output end of the liquid inlet pipe 21 is connected to the input end of the water pump 2, the input end of the liquid outlet pipe 22 is connected to the output end of the water pump 2, the output end of the liquid outlet pipe 22 is connected to the side wall of the cabinet 1, the liquid inlet valve 211 is arranged at the end of the liquid inlet pipe 21 connected to the water pump 2, and the liquid outlet valve 221 is arranged at the end of the liquid outlet pipe 22 connected to the water pump 2.

[0031] It should be noted that the coolant with a lower temperature is transported to the input end of the liquid inlet pipe 21, so that the heat generated by the component to be cooled arranged near the liquid inlet pipe 21 is transferred to the coolant. The coolant carrying the heat enters the liquid outlet pipe 22 through the input end of the liquid outlet pipe 22 under the drive of the water pump 2, and is discharged to the outside through the output end of the liquid outlet pipe 22, thereby cooling the component to be cooled and avoiding excessive heat accumulation inside the cabinet 1.

[0032] It is understandable that the distance between the inlet valve 211 and the end of the inlet pipe 21 facing the water pump 2, and the distance between the outlet valve 221 and the end of the outlet pipe 22 facing the water pump 2 can be flexibly adjusted according to actual needs, and no excessive restrictions are made here.

[0033] The conveying assembly 3 is connected to the first liquid inlet section 212 and / or the first liquid outlet section 222, and is used to connect the first liquid inlet section 212 and / or the first liquid outlet section 222 to the outside. In this embodiment, two groups of conveying assemblies 3 are provided, and the two groups of conveying assemblies 3 are connected to the first liquid inlet section 212 and the first liquid outlet section 222 respectively.

[0034] In this way, when the water pump 2 needs to be replaced and maintained, the liquid inlet valve 211 and the liquid outlet valve 221 are closed to stop the flow of the coolant in the second liquid inlet section 213 and the second liquid outlet section 223. The coolant in the first liquid inlet section 212 and the second liquid inlet section 213 can be transported to the outside under the action of the conveying component 3, thereby avoiding the discharge of all the coolant in the liquid inlet pipe 21 and the liquid outlet pipe 22 in order to replace the maintenance water pump 2, and avoiding the leakage of the coolant in the liquid inlet pipe 21 and the liquid outlet pipe 22 when the water pump 2 is disassembled, thereby reducing the waste of coolant, simplifying the drainage steps, and improving maintenance efficiency.

[0035] See also Figure 1 In some embodiments, the cabinet 1 is detachably connected with an air inlet net 11, and the water pump 2 is arranged on a side of the cabinet 1 facing the air inlet net 11. The liquid outlet pipe 22 is arranged on a side of the cabinet 1 close to the air inlet net 11, and the air inlet net 11 is provided with a plurality of filter holes (not shown in the figure) for filtering dust from the outside. A mounting frame 14 with a top surface opening is arranged on a side of the cabinet 1 facing the air inlet net 11 corresponding to the air inlet net 11, and the air inlet net 11 is slidably connected to the mounting frame 14.

[0036] In this way, the air inlet net 11 can connect the interior of the cabinet 1 with the outside world, ensure good ventilation inside the cabinet 1, avoid the accumulation of heat-carrying air inside the cabinet 1, and prevent external dust and other debris from entering the interior of the cabinet 1; the water pump 2 is arranged at a position close to the air inlet net 11, which can facilitate the staff to remove the air inlet net 11 and then take out the water pump 2 through the position where the air inlet net 11 is installed in the cabinet 1, and the liquid outlet pipe 22 with a higher temperature is arranged close to the air inlet net 11 to improve the heat dissipation efficiency.

[0037] It is understandable that the air inlet mesh 11 can also be detachably connected to the side wall of the cabinet 1 by bolts, and the connection method between the air inlet mesh 11 and the cabinet 1 can be flexibly adjusted according to actual needs, as long as it can be detachably connected to the cabinet 1, and no further examples are given here.

[0038] See also Figure 1 In some embodiments, a water inlet 12 and a water outlet 13 are provided on the cabinet 1, and the water inlet 12 and the water outlet 13 are arranged on the same side of the air inlet network 11, the input end of the liquid inlet pipe 21 passes through the water inlet 12 to be connected to the cabinet 1, and the output end of the liquid outlet pipe 22 passes through the water outlet 13 to be connected to the cabinet 1.

[0039] In this embodiment, the water inlet 12 and the water outlet 13 are both arranged on one side of the length direction of the air inlet network 11 , and the input end of the liquid inlet pipe 21 and the output end of the liquid outlet pipe 22 are both plugged into the cabinet 1 .

[0040] In this way, the input end of the liquid inlet pipe 21 and the output end of the liquid outlet pipe 22 are both arranged on the side wall of the cabinet 1 where the air inlet net 11 is installed, which can facilitate the staff to remove the air inlet net 11 and maintain the liquid inlet pipe 21 and the liquid outlet pipe 22, thereby improving the maintenance efficiency; and facilitate the coolant in the first liquid inlet section 212 and the first liquid outlet section 222 to be transported to the outside by the conveying component 3, thereby avoiding the coolant leakage and remaining inside the cabinet 1 when replacing and maintaining the water pump 2.

[0041] It is understandable that the positions of the air inlet and the air outlet can be flexibly adjusted and are not limited to one side in the length direction of the air inlet net 11, but can also be respectively set on both sides of the air inlet net 11, which will not be elaborated here.

[0042] See also Figure 2 In some embodiments, the conveying component 3 includes a first connecting pipe 31 and a second connecting pipe 32, both of which are located inside the cabinet 1, the first connecting pipe 31 is arranged at the first liquid inlet section 212 and is connected to the first liquid inlet section 212, and the second connecting pipe 32 is arranged at the first liquid outlet section 222 and is connected to the first liquid outlet section 222.

[0043] Among them, the first connecting pipe 31 and the second connecting pipe 32 are both hard pipes. The first connecting pipe 31 is fixedly connected to the first liquid inlet section 212, and the second connecting pipe 32 is fixedly connected to the first liquid outlet section 222, and is used to discharge the cooling liquid in the first liquid inlet section 212 and the first liquid outlet section 222.

[0044] In this way, when replacing the water pump 2, the liquid inlet valve 211 and the liquid outlet valve 221 are closed, so that the coolant in the second liquid inlet section 213 will not flow into the first liquid inlet section 212, and the coolant in the second liquid outlet section 223 will not flow into the first liquid outlet section 222, ensuring that most of the coolant in the liquid inlet pipe 21 and the liquid outlet pipe 22 remain inside, and the less coolant in the first liquid inlet section 212 is discharged to the outside through the first connecting pipe 31, and the less coolant in the first liquid outlet section 222 is discharged to the outside through the second connecting pipe 32, thereby emptying the first liquid inlet section 212 and the second liquid outlet section 223, avoiding the coolant from leaking into the cabinet 1 after removing the water pump 2, reducing the waste of coolant, saving subsequent cleaning steps, and improving maintenance efficiency.

[0045] See also Figure 2 In some embodiments, the energy storage liquid cooling unit further includes two stoppers 4, which are respectively connected to the first connecting pipe 31 and the second connecting pipe 32, and are used to block the first connecting pipe 31 and the second connecting pipe 32. In this embodiment, the stopper 4 is a pipe plug.

[0046] It should be noted that when the energy storage liquid cooling unit is working normally, the pipe plug is inserted into the first connecting pipe 31 and the second connecting pipe 32 to isolate the first liquid inlet section 212 and the first liquid outlet section 222 from the outside world to prevent leakage of the coolant during the circulation process; when replacing the water pump 2, after the first liquid inlet section 212 and the first liquid outlet section 222 are emptied, the pipe plug can also be promptly sealed on the first connecting pipe 31 and the second connecting pipe 32 to prevent dust from entering the first liquid inlet section 212 and the first liquid outlet section 222, so that the staff can flexibly adjust the connectivity between the first liquid inlet section 212 and the first liquid outlet section 222 and the outside world, thereby improving maintenance efficiency.

[0047] It is understandable that the shut-off member 4 can also be two valves correspondingly arranged on the first connecting pipe 31 and the second connecting pipe 32. The specific structure of the shut-off member 4 can be flexibly adjusted to enable the first connecting pipe 31 to be connected to the outside world and the second connecting pipe 32 to be connected to the outside world selectively.

[0048] See also Figure 1 and Figure 2 In some embodiments, the cross-sectional area of ​​the first connecting pipe 31 is smaller than the cross-sectional area of ​​the first liquid inlet section 212, and the cross-sectional area of ​​the second connecting pipe 32 is smaller than the cross-sectional area of ​​the first liquid outlet section 222. The cross-sectional area of ​​the first connecting pipe 31 is the same as the cross-sectional area of ​​the second connecting pipe 32.

[0049] In this way, the first connecting pipe 31 and the second connecting pipe 32 have a smaller cross-sectional area, which can save the space they occupy inside the cabinet 1 and avoid affecting the normal installation of other components inside the cabinet 1. Since there is less coolant in the first liquid inlet section 212 and the first liquid outlet section 222, the first connecting pipe 31 and the second connecting pipe 32 with a smaller cross-sectional area can also achieve the effect of quickly discharging the coolant.

[0050] See also Figure 1 and Figure 2 In some embodiments, the distance between one end of the first connecting pipe 31 away from the first liquid inlet section 212 and the bottom surface of the cabinet 1 is not greater than the distance between the liquid inlet valve 211 and the bottom surface of the cabinet 1, and the distance between one end of the second connecting pipe 32 away from the first liquid outlet section 222 and the bottom surface of the cabinet 1 is not greater than the distance between the liquid outlet valve 221 and the bottom surface of the cabinet 1.

[0051] In this embodiment, the first connecting pipe 31 and the second connecting pipe 32 are both flush with the bottom surface of the cabinet 1. The distance between the first connecting pipe 31 and the bottom surface of the cabinet 1 is equal to the distance between the liquid inlet valve 211 and the bottom surface of the cabinet 1. The distance between the second connecting pipe 32 and the bottom surface of the cabinet 1 is equal to the distance between the liquid outlet valve 221 and the bottom surface of the cabinet 1.

[0052] In this way, when the first connecting pipe 31 and the second connecting pipe 32 are connected to the outside, the coolant in the first liquid inlet section 212 and the first liquid outlet section 222 can automatically flow into the first connecting pipe 31 and the second connecting pipe 32 under the action of its own gravity, thereby improving the emptying efficiency of the first liquid inlet section 212 and the second liquid inlet section 213, thereby improving the maintenance efficiency and facilitating the rapid replacement of the water pump 2.

[0053] It is understandable that the first connecting pipe 31 and the second connecting pipe 32 can also be tilted downward to further increase the speed of cooling liquid discharge, and the distance between the first connecting pipe 31 and the second connecting pipe 32 and the bottom surface of the cabinet 1 can be flexibly adjusted, which will not be listed in detail here.

[0054] See also Figure 2 In some embodiments, the diameter of the first connecting tube 31 is 0.8 cm-1 cm, and the diameter of the second connecting tube 32 is 0.8 cm-1 cm. For example, the diameter of the first connecting tube 31 can be 0.8 cm, 0.9 cm, 1 cm, and the diameter of the second connecting tube 32 can also be 0.8 cm, 0.9 cm, 1 cm. The diameters of the first connecting tube 31 and the second connecting tube 32 can be flexibly adjusted.

[0055] See also Figure 1 and Figure 2 In some embodiments, the energy storage liquid cooling unit further includes a first delivery pipe (not shown in the figure) and a second delivery pipe (not shown in the figure), at least a portion of the first delivery pipe and at least a portion of the second delivery pipe are located inside the cabinet 1, one end of the first delivery pipe is connected to an end of the first connecting pipe 31 away from the first liquid inlet section 212, and one end of the second delivery pipe is connected to an end of the second connecting pipe 32 away from the first liquid outlet section 222.

[0056] The first delivery pipe and the second delivery pipe are both hoses. The first delivery pipe is detachably connected to the first connecting pipe 31 , and the second delivery pipe is detachably connected to the second connecting pipe 32 .

[0057] In this way, the end of the first delivery pipe away from the first connecting pipe 31 and the end of the second delivery pipe away from the second connecting pipe 32 are led out of the cabinet 1, so that the coolant in the first liquid inlet section 212 and the first liquid outlet section 222 can be directly discharged to the outside, avoiding the coolant remaining inside the cabinet 1 when the water pump 2 is replaced.

[0058] It can be understood that the materials of the first connecting tube 31, the second connecting tube 32, the first delivery tube, and the second delivery tube can be flexibly adjusted. In this embodiment, the first connecting tube 31 and the second connecting tube 32 are hard tubes to facilitate the corresponding installation of the first delivery tube and the second delivery tube. The first delivery tube and the second delivery tube are soft tubes to facilitate the discharge of the coolant to the outside.

[0059] See also Figure 2In some embodiments, the delivery assembly 3 further includes a liquid delivery member (not shown in the figure), which is disposed at one end of the first delivery pipe away from the first connecting pipe 31, and at one end of the second delivery pipe away from the second connecting pipe 32. The liquid delivery member is a bidirectional water pump.

[0060] In this way, when the water pump 2 is replaced, the liquid conveying component can drain the liquid in the first liquid inlet section 212 and the second liquid inlet section 213 to avoid leakage of coolant after the water pump 2 is removed; after the maintenance is completed, the first liquid inlet section 212 and the second liquid inlet section 213 can also be replenished before connecting the water pump 2 to the liquid inlet pipe 21 and the liquid outlet pipe 22 to avoid a large amount of air remaining in the liquid inlet pipe 21 and the liquid outlet pipe 22 after the water pump 2 is removed, affecting the normal circulation of the coolant in the liquid inlet pipe 21 and the liquid outlet pipe 22.

[0061] Furthermore, the first delivery pipe and the second delivery pipe can be connected in parallel to a main pipe (not shown in the figure), and the liquid delivery component is arranged on the main pipe to save the number of liquid delivery components.

[0062] It is understandable that the liquid conveying member may also be a structure for conveying fluid in one direction or two directions, such as an air pressure pump, as long as it can realize directional conveying of the cooling liquid, and no further examples are given here.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
