Description

Technical Field

[0001] This utility model belongs to the field of electric energy storage technology, specifically a partitioned immersion energy storage chamber. Background Technology

[0002] Currently, with the continuous improvement of my country's energy consumption structure, the energy storage battery industry is experiencing explosive growth, and the safety and stability of energy storage systems are attracting increasing attention. During charging and discharging, energy storage batteries generate a large amount of heat due to ohmic heat and polarization heat. If this heat cannot dissipate in time, its accumulation inside the battery can increase the rate of side reactions at the battery interface, and excessive heat accumulation may lead to thermal runaway. Therefore, efficient heat dissipation measures are a crucial consideration in energy storage battery design.

[0003] Currently, energy storage systems primarily employ two cooling methods: air cooling and liquid cooling. Air cooling mainly uses air conditioning, with air as the cooling medium. This method has low energy efficiency, a large equipment footprint, and poor temperature uniformity in the energy storage batteries. Liquid cooling uses water as the cooling medium through cooling plates. Heat exchange occurs between the cooling medium flowing within the cooling plates and the energy storage batteries. Heat must pass through the battery casing and cooling plates before finally being transferred to the cooling medium, which then dissipates the heat through a radiator. This process involves multiple heat transfer stages, high thermal resistance, and low heat exchange efficiency, resulting in high requirements for radiator performance.

[0004] To improve the heat dissipation performance of energy storage systems, submerged energy storage systems, which immerse energy storage batteries in a liquid medium, have seen rapid development. Submerged energy storage systems utilize heat exchange between the liquid medium and the battery to dissipate heat. However, most existing submerged energy storage systems employ static immersion, and after prolonged operation, the temperature gradually rises due to the accumulation of heat within the liquid medium. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a partitioned immersion energy storage chamber, which can improve the flow uniformity of the temperature control medium and improve the temperature control uniformity by adopting immersion, overflow and forced flow methods.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0040] like Figure 3-8 As shown, this embodiment of a fully submerged energy storage tank based on partitioned overflow includes a tank body 100, with an opening and closing door 103 on the front side of the tank body 100. The tank body 100 of this embodiment has a central energy storage area in its middle section, within which a mounting frame 200 is provided. That is, the tank body 100 of this embodiment has a mounting frame 200, and the mounting frame 200 has at least one layer of sealing mounting assembly, within which an energy storage pack 10 is installed. The sealing mounting assembly of this embodiment includes a lower sealing mounting frame 210 for sealingly engaging with the bottom of the energy storage pack 10 and an upper sealing mounting frame 230 for sealingly engaging with the top of the energy storage pack 10.

[0041] In this embodiment, the lower sealing mounting bracket 210 is provided with a lower support surface 211 for supporting the energy storage pack 10. A lower sealing gasket 13 is provided between the bottom surface of the energy storage pack 10 and the lower support surface 211, and a sealing fit is achieved by the gravity of the energy storage pack 10. In this embodiment, the lower sealing gasket 13 is installed on the bottom surface of the energy storage pack 10, such as... Figure 2 As shown.

[0042] In this embodiment, the upper sealing mounting bracket 230 includes a rear flow channel baffle 231, a left flow channel baffle 232, and a right flow channel baffle 233 located on the rear, left, and right sides of the energy storage pack 10, respectively. The rear flow channel baffle 231, left flow channel baffle 232, and right flow channel baffle 233 are each provided with an upper support surface 234 in the horizontal direction. An upper sealing gasket 14 is provided between the top plate 11 of the energy storage pack 10 and the upper support surface 234 located below it, and a sealing fit is achieved by the gravity of the energy storage pack 10. In this embodiment, the upper sealing gasket 14 is installed on the lower surface of the top plate 11, such as... Figure 1 As shown.

[0043] like Figure 9 As shown, in this embodiment, a front sealing surface 201 is provided between the upper sealing mounting bracket 230 and the lower sealing mounting bracket 210, located on the left and right sides of the front side of the energy storage pack 10. A front sealing gasket 202 is provided between the panel 16 of the energy storage pack 10 and the front sealing surface 201 located behind it to achieve a sealing fit. In this embodiment, the front sealing gasket 202 is installed on the front sealing surface 201. Specifically, in this embodiment, a front sealing plate 203 is provided between the upper sealing mounting bracket 210 and the lower sealing mounting bracket 230, located on the left and right sides of the front side of the energy storage pack 10. The front side of the front sealing plate 203 is designated as the front sealing surface 201, and the front sealing gasket 202 is installed on the front side of the front sealing plate 203.

[0044] like Figure 10As shown, in this embodiment, a rear sealing surface 204 is provided between the upper sealing mounting bracket 230 and the lower sealing mounting bracket 210, located on the left and right sides of the rear side of the energy storage pack 10, respectively. A rear sealing gasket 205 is provided between the back of the energy storage pack 10 and the rear sealing surface 204 located behind it to achieve a sealing fit. In this embodiment, the rear sealing gasket 205 is installed on the rear sealing surface 204. In this embodiment, a rear sealing plate 206 is provided between the rear flow channel baffle 231 and the left flow channel baffle 232, and between the rear flow channel baffle 231 and the right flow channel baffle 233, respectively. The front side of the rear sealing plate 206 is set as the rear sealing surface 204, that is, the rear sealing surface 204 is set on the rear sealing plate 206, and the rear sealing gasket 205 is installed on the front side of the rear sealing plate 206. The two rear sealing plates 204 respectively seal with the left and right sides of the rear side of the energy storage pack 10.

[0045] Specifically, in this embodiment, the energy storage pack 10 is equipped with a roller 12 that exposes its bottom surface, and the lower support surface 211 is provided with an inclined surface 212 that cooperates with the roller 12. During the installation of the energy storage pack 10, the roller 12 is located on the lower support surface 211, and there are gaps between the bottom surface and the top plate 11 of the energy storage pack 10 and the lower support surface 211 and the upper support surface 234, respectively. When the roller 12 enters the inclined plane 212, the inclined plane 212 guides the movement direction of the energy storage pack 10, causing the front sealing gasket 202 and the rear sealing gasket 205 of the energy storage pack 10 to be compressed respectively. At the same time, the energy storage pack 10 has a downward velocity component, causing the bottom surface and top plate of the energy storage pack 10 to be compressed respectively. In this way, the technical objectives of sealing the bottom surface of the energy storage pack 10 with the lower support surface 211 through the lower sealing gasket 13, sealing the top plate 11 of the energy storage pack 10 with the upper support surface 234 through the upper sealing gasket 14, sealing the front sealing surface 201 with the front sealing gasket 202, and sealing the back surface of the energy storage pack 10 with the rear sealing surface 204 through the rear sealing gasket 205 can be achieved. Once the energy storage pack 10 is installed, its weight is primarily borne by the upper support surface 234 and the lower support surface 211, providing sealing pressure between the energy storage pack 10 and these surfaces. Simultaneously, the sealing pressure between the energy storage pack 10 and the front sealing surface 201 and the rear sealing surface 204 is mainly provided by the static friction between the energy storage pack 10 and the upper support surface 234 and the lower support surface 211. Specifically, in this embodiment, the roller 12 is located behind the rear side of the energy storage pack 10, and the inclined surface 212 is positioned behind the rear sealing surface 203 to prevent the inclined surface 212 from affecting the seal between the bottom surface of the energy storage pack 10 and the lower support surface 211.

[0046] In a preferred embodiment of this example, the upper sealing mounting bracket 230 includes a first upper sealing mounting bracket located at the top, and the remaining upper sealing mounting brackets are second upper sealing mounting brackets; the second upper sealing mounting brackets are disposed on the lower sealing mounting bracket 210 located above them, which simplifies the structure and saves space inside the compartment 100.

[0047] In a preferred embodiment of this example, the compartment 100 is provided with sealing plates surrounding the mounting frame, that is, sealing plates are installed around the mounting frame 200. The sealing plates and the front, rear, left, and right sides of the energy storage pack 10 respectively form a front immersion area 110, a rear overflow area 120, a left immersion area 130, and a right immersion area 140. Specifically, the compartment 100 in this embodiment has a central energy storage area in the middle, and the mounting frame 200 is provided in the central energy storage area. The mounting frame 200 is surrounded by sealing plates, and at least one layer of energy storage pack 10 is installed in the mounting frame 200 in the central energy storage area. The mounting frame 200 and the energy storage pack 10 are sealed together. The central energy storage area is provided with a front immersion area 110 and a rear overflow area 120 on the front and rear sides respectively. The central energy storage area is provided with a left immersion area 130 and a right immersion area 140 on the left and right sides respectively. The front immersion area 110 is located between the front side of the energy storage pack 10 and the sealing plate. The rear overflow area 120 is located between the rear side of the energy storage pack 10 and the sealing plate. The left immersion area 130 is located between the left side of the energy storage pack 10 and the sealing plate. The right immersion area 140 is located between the right side of the energy storage pack 10 and the sealing plate.

[0048] In this embodiment, the sealing plate is sealed in conjunction with the lower sealing mounting bracket 210 and the upper sealing mounting bracket 230. In this way, the front immersion area 110, the rear overflow area 120, the left immersion area 130 and the right immersion area 140 can be respectively confined around the mounting bracket 200. By injecting flowing temperature control medium into the front immersion area 110, the rear overflow area 120, the left immersion area 130 and the right immersion area 140, temperature control of the energy storage pack 10 can be achieved, and the space occupied by the front immersion area 110, the rear overflow area 120, the left immersion area 130 and the right immersion area 140 can be reduced. In this embodiment, the upper sealing mounting bracket 230 is mounted on the lower sealing mounting bracket 210 located above it. Specifically, the rear flow channel baffle 231, the left flow channel baffle 232, and the right flow channel baffle 233 are welded and fixed to the lower sealing mounting bracket 210 located above it. Therefore, it is only necessary to seal the sealing plate with the lower sealing mounting bracket 210. In this embodiment, the rear, left, and right sides of the lower sealing mounting bracket 210 are welded and fixed to the sealing plate.

[0049] In this embodiment, in order to discharge the temperature-controlled medium in the energy storage pack 10 into the rear overflow area 120, the middle energy storage area and each layer of energy storage pack 10 are provided with overflow holes 21, which are connected to the rear overflow area 120. That is, the fully submerged energy storage tank based on partitioned overflow in this embodiment also includes overflow holes 213 for the temperature-controlled medium in the energy storage pack 10 to flow into the rear overflow area 120. In some embodiments, the overflow holes 213 are provided on the rear flow channel baffle 231; in other embodiments, the overflow holes 213 are provided on the lower sealing mounting bracket 210. Specifically, in this embodiment, the overflow holes 213 are provided on the lower sealing mounting bracket 210, and the overflow holes 213 are located on the lower support surface 211 between the rear flow channel baffle 231 and the rear side of the energy storage pack 10. By providing the overflow hole 213, the temperature-controlled medium inside the energy storage pack 10 can enter the rear overflow area 120, thereby realizing the flow of the temperature-controlled medium inside the energy storage pack 10. In addition, in some embodiments, the overflow hole 21 can also be provided on the energy storage pack 10, which will not be described in detail here.

[0050] Since the lower sealing mounting bracket 210 is in a tight fit with the sealing plate, but the rear overflow area 120 needs to be vertically connected, in this embodiment, the area of ​​the lower support surface 211 between the rear flow channel baffle 231 and the sealing plate is provided with a rear perforated hole 214 for vertically connecting the rear overflow area 120. Similarly, in this embodiment, the front immersion area 110 is vertically connected; therefore, in this embodiment, the area of ​​the lower support surface 211 between the front sealing surface 201 and the sealing plate is provided with a front perforated hole 215 for vertically connecting the front immersion area 110.

[0051] In this embodiment, a plurality of side flow channels 131, 141 are provided in the left immersion zone 130 and the right immersion zone 140 along the top-to-bottom direction. The front ends of the side flow channels 131, 141 are connected to the front immersion zone 110, and the rear ends are connected to the rear overflow zone 120. In this embodiment, at least one side flow channel 131, 141 is provided in the left immersion zone 130 and the right immersion zone 140 corresponding to each layer of energy storage pack 10. In this embodiment, one side flow channel 131, 141 is provided in the left immersion zone 130 and the right immersion zone 140 corresponding to each layer of energy storage pack 10. Of course, in some other embodiments, two or more side flow channels 131, 141 may be provided in the left immersion zone 130 and the right immersion zone 140 corresponding to each layer of energy storage pack 10, which will not be described in detail here. In this embodiment, a side flow channel is formed between two adjacent lower sealing mounting brackets 210. Side flow channel 131 is located within the left immersion zone 130, and side flow channel 141 is located within the right immersion zone 140. The rear ends of side flow channels 131 and 141 are provided with liquid outlets communicating with the rear overflow zone 120, and these outlets are located on the rear sealing plate 204. Specifically, the liquid outlets are located in the area between the side of the energy storage pack 10 and the sealing plate. In this embodiment, the temperature control medium is injected into the front immersion zone 110, and the temperature control medium in the front immersion zone 110 is diverted into the side flow channels 131 and 141, and then flows into the rear overflow zone 120 through the liquid outlets. Specifically, during temperature control, in order to maintain the liquid level of the temperature control medium in the front immersion zone 110 within the set range, the flow rate of the temperature control medium injected into the front immersion zone 110 should be consistent with the flow rate of the temperature control medium flowing into the rear overflow zone 120 through each outlet hole. That is, in this embodiment, the flow rate of the temperature control medium injected into the front immersion zone 110 is controlled by the flow rate of the temperature control medium flowing into the rear overflow zone 120 through each outlet hole.

[0052] In this embodiment, the front ends of the side flow channels 131 and 141 are connected to the front immersion zone 110. Thus, the temperature-controlled medium in the front immersion zone 110 can enter the rear overflow zone 120 through the side flow channels 131 and 141, ensuring sufficient flow of the temperature-controlled medium in the front immersion zone 110, the left immersion zone 130, and the right immersion zone 140. Preferably, to avoid the formation of dead zones where the temperature-controlled medium does not flow in local areas of the side flow channels 131 and 141, the outlet holes in this embodiment include at least upper outlet holes 132 and 142 located at the upper end of the side flow channels 131 and 141. The lower ends of the side flow channels 131 and 141 in this embodiment are also provided with lower outlet holes 133 and 143. Specifically, in this embodiment, an upper liquid outlet 132 and a lower liquid outlet 133 are respectively provided at the upper and lower ends of the side flow channel 131, and an upper liquid outlet 142 and a lower liquid outlet 143 are respectively provided at the upper and lower ends of the side flow channel 141. Similarly, a liquid inlet (not shown in the figure) communicating with the front immersion area 110 is provided at the front end of the side flow channel 131, and the liquid inlet includes at least one lower liquid inlet located on the lower side of the front end of the side flow channel 131.

[0053] In this embodiment, the sealing plate includes a front sealing plate 151 and a rear sealing plate 152. The front sealing plate 151 is located on the front side of the mounting frame 200. A handle 153 is provided on the front sealing plate 151 corresponding to each lower sealing mounting frame 210. A buckle hole 216 is provided on the lower support surface 211 to mate with the handle 153. In this embodiment, the buckle hole 216 is located in the area between the front side of the energy storage pack 100 and the front sealing plate 151. The mating of the handle 153 and the buckle hole 216 facilitates the installation and fixing of the front sealing plate 152, and allows the application of the force required for sealing the front sealing plate 151 with the lower sealing mounting frame 210. Simultaneously, the front sealing plate 152 is also fixedly connected to the mounting frame 200 via threaded fasteners. The rear sealing plate 152 is located on the rear, left, and right sides of the mounting frame 200. That is, the sealing plates on the rear, left, and right sides of the mounting frame 200 are integrated, which simplifies the structure and ensures the sealing performance at the joints between the sealing plates on the rear, left, and right sides of the mounting frame 200. In this embodiment, the rear sealing plate 152 is welded and fixed to the rear, left, and right sides of the mounting frame 200. In a preferred embodiment, a reinforcing frame 154 is also included to strengthen the structural strength of the sealing plate. Specifically, the side of the sealing plate facing away from the mounting frame 200 is provided with a reinforcing frame 154 to prevent the sealing plate from bulging outward under liquid pressure. Specifically, the reinforcing frame 154 on the front sealing plate 151 is fixedly mounted on the front sealing plate, while the reinforcing frame 154 on the rear sealing plate 152 is fixed to the support frame of the outer shell 101.

A second inlet control valve 108 is provided on the second inlet pipe 107 for injecting temperature-controlled medium into the front immersion zone 110. Since the left immersion zone 130 and the right immersion zone 140 are both connected to the front immersion zone 110, the temperature-controlled medium injected into the front immersion zone 110 will also enter the left immersion zone 130 and the right immersion zone 140, and be discharged through the rear overflow zone 120. In this embodiment, a liquid level sensor is provided in the front immersion zone 110 for detecting the liquid level, so as to realize real-time monitoring and detection of the liquid level of the temperature-controlled medium in the front immersion zone 110, the left immersion zone 130, and the right immersion zone 140.
