Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled energy storage cabinet technology, and in particular to a liquid-cooled energy storage cabinet with uniform flow rate. Background Technology

[0002] Liquid-cooled energy storage cabinets are energy storage devices that use liquid cooling technology. They are mainly used in energy storage projects with high energy density and high charge and discharge speed. Liquid cooling technology reduces the internal temperature of the equipment through liquid circulation. Compared with traditional air cooling technology, liquid cooling has higher heat dissipation efficiency and better temperature control. Liquid-cooled energy storage cabinets are generally suitable for large-scale energy storage projects and can maintain stable operation and extend service life of the equipment under conditions of large changes in ambient temperature.

[0003] Existing liquid-cooled energy storage cabinets suffer from inconsistent coolant flow rates to individual battery modules due to varying pipe lengths, leading to temperature differences between batteries and accelerating battery performance degradation. Therefore, we propose a liquid-cooled energy storage cabinet with uniform flow rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. In existing liquid-cooled energy storage cabinets, when dissipating heat from the internal battery modules, the varying lengths of the pipes cause deviations in the flow rate of coolant to each battery module, resulting in temperature differences between the batteries and accelerating the degradation of battery performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid-cooled energy storage cabinet with uniform flow rate includes a cabinet body. A storage tank is installed at the top of the cabinet body. Several water pumps are symmetrically installed at equal intervals on the bottom surface of the storage tank. The output end of the water pump extends to the inner side of the cabinet body and is equipped with a main distribution pipe. Several flow channels are equidistantly formed at one end of the main distribution pipe away from the output end of the water pump. A branch pipe is fixed around the periphery of the flow channels. A flow equalizer is fitted on the outer wall of the branch pipe. A cooling plate is fixed at one end of the branch pipe away from the main distribution pipe. An S-shaped cooling groove is formed inside the cooling plate.

[0007] As a preferred embodiment of this utility model, a number of temperature sensors are fixed at equal intervals on the inner top surface of the cabinet.

[0008] The technical advantage of adopting the above-mentioned further solution is that the temperature inside the cabinet can be monitored in real time more conveniently through the design of the temperature sensor.

[0009] As a preferred embodiment of this utility model, the output end of the water pump is connected to the main diversion pipe, and the main diversion pipe and the branch diversion pipe are connected through a flow channel.

[0010] The technical effect of adopting the above-mentioned further solution is that by connecting the output end of the water pump to the main distribution pipe and connecting the main distribution pipe to the branch pipe through the flow channel, the water pump can draw the coolant inside the storage tank and send it into the branch pipe through the main distribution pipe and the flow channel.

[0011] As a preferred embodiment of this utility model, the flow equalizer is adapted to the branch pipe.

[0012] The technical effect of adopting the above-mentioned further solution is that by matching the flow equalizer with the branch pipe, the flow equalizer can control the flow rate of the coolant passing through the branch pipe, thereby enabling the coolant to be delivered evenly.

[0013] As a preferred embodiment of this utility model, the branch pipe is connected to the S-shaped cooling tank, and the cooling plate is made of aluminum alloy.

[0014] The technical effect of adopting the above-mentioned further solution is that by connecting the branch pipe to the S-shaped cooling tank, the coolant can enter the interior of the S-shaped cooling tank through the branch pipe to assist the cooling plate in dissipating heat and cooling the battery pack. The cooling plate made of aluminum alloy has good thermal conductivity, high strength, is easy to process and form, and has good corrosion resistance and weldability.

[0015] As a preferred embodiment of this utility model, the storage box contains coolant, and an injection groove is provided at the top of the storage box, which is connected to the interior of the storage box.

[0016] The technical advantage of adopting the above-mentioned further solution is that by connecting the injection tank to the inside of the storage box, it is easier for staff to add coolant to the inside of the storage box through the injection tank.

[0017] As a preferred embodiment of this utility model, a battery pack is installed between the cooling plates, and the cooling plates are adapted to the battery pack.

[0018] The technical effect of adopting the above-mentioned further solution is that by adapting the cooling plate to the battery pack, the cooling plate can better dissipate heat and cool the battery pack.

[0019] As a preferred embodiment of this utility model, the S-shaped cooling tank extends from the side away from the branch pipe into the interior of the storage tank and is connected to a return pipe.

[0020] The technical advantage of adopting the above-mentioned further solution is that, through the design of the return pipe, the coolant that has undergone heat exchange can flow back into the storage tank for reuse, thus saving resources.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] In this invention, through the design of a water pump, a main distribution pipe, a flow channel, branch distribution pipes, and a flow equalizer, when a liquid-cooled energy storage cabinet with uniform flow is used to dissipate heat from the battery, the flow rate of the coolant is the same when cooling each battery module, thus avoiding temperature differences between batteries and effectively preventing the degradation of battery performance.

[0032] Example 1:

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a liquid-cooled energy storage cabinet with uniform flow rate, including a cabinet body 1. A storage tank 2 is installed at the top of the cabinet body 1. Several water pumps 201 are symmetrically installed at equal intervals on the inner bottom surface of the storage tank 2. The output end of the water pump 201 extends to the inner side of the cabinet body 1 and is equipped with a main diversion pipe 202. Several flow channels 203 are equidistantly opened at one end of the main diversion pipe 202 away from the output end of the water pump 201. Diversion branch pipes 204 are fixed around the flow channels 203. The water pump 201 will draw water... The coolant inside the storage tank 2 is fed into the branch pipe 204 through the main branch pipe 202 and the flow channel 203. A flow equalizer 205 is fitted on the outer wall of the branch pipe 204. The flow equalizer 205 can control the flow rate of the coolant entering the branch pipe 204. A cooling plate 3 is fixed at the end of the branch pipe 204 away from the main branch pipe 202. An S-shaped cooling groove 301 is opened inside the cooling plate 3. The coolant can enter the S-shaped cooling groove 301 to assist the cooling plate 3 in dissipating heat and cooling the battery pack 302.

[0034] Example 2:

[0035] like Figures 1-4 As shown, several temperature sensors 101 are fixed at equal intervals on the inner top surface of the cabinet 1. The design of the temperature sensors 101 makes it relatively convenient to monitor the temperature inside the cabinet 1 in real time.

[0036] The output end of the water pump 201 is connected to the main branch pipe 202, and the main branch pipe 202 is connected to the branch pipe 204 through the flow channel 203. Through the connection between the output end of the water pump 201 and the main branch pipe 202, and the connection between the main branch pipe 202 and the branch pipe 204 through the flow channel 203, the water pump 201 can draw coolant from the storage tank 2 and send it into the branch pipe 204 through the main branch pipe 202 and the flow channel 203.

[0037] The flow equalizer 205 is adapted to the branch pipe 204. Through the adaptation of the flow equalizer 205 to the branch pipe 204, the flow equalizer 205 can control the flow rate of the coolant passing through the branch pipe 204, thereby delivering the coolant evenly.

[0038] The branch pipe 204 is connected to the S-shaped cooling tank 301. The cooling plate 3 is made of aluminum alloy. The branch pipe 204 is connected to the S-shaped cooling tank 301, so that the coolant can enter the interior of the S-shaped cooling tank 301 through the branch pipe 204 to assist the cooling plate 3 in dissipating heat and cooling the battery pack 302. The cooling plate 3 made of aluminum alloy has good thermal conductivity, high strength, is easy to process and form, and has good corrosion resistance and weldability.

[0039] The storage tank 2 stores coolant inside. An injection groove 206 is provided at the top of the storage tank 2. The injection groove 206 is connected to the inside of the storage tank 2. The connection between the injection groove 206 and the inside of the storage tank 2 makes it convenient for staff to add coolant to the inside of the storage tank 2 through the injection groove 206.

[0040] A battery pack 302 is installed between the cooling plates 3. The cooling plates 3 and the battery pack 302 are adapted to each other. Through the adaptation of the cooling plates 3 and the battery pack 302, the cooling plates 3 can better dissipate heat and cool down the battery pack 302.

[0041] The S-shaped cooling tank 301 extends from the side away from the branch pipe 204 into the interior of the storage tank 2 and is connected to the return pipe 303. The design of the return pipe 303 allows the coolant that has undergone heat exchange to flow back into the interior of the storage tank 2 for reuse, thus saving resources.

[0042] The working process of this utility model is as follows: When using a liquid-cooled energy storage cabinet with uniform flow to dissipate heat from the battery, the water pump 201 is first turned on to draw coolant from the storage tank 2 and send it into the main distribution pipe 202. After entering the main distribution pipe 202, the coolant quickly passes through the flow channel 203 to reach the branch pipe 204. At this time, the flow equalizer 205 can accurately control the flow rate of the coolant, so that the flow rate of coolant entering the branch pipe 204 is the same. Subsequently, the coolant enters the S-shaped cooling tank 301 to assist the cooling plate 3 in dissipating heat and cooling the battery pack 302. Compared with existing liquid-cooled energy storage cabinets, the coolant flow rate is the same when dissipating heat and cooling each battery module, avoiding temperature differences between batteries and effectively preventing battery performance degradation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
