Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric energy storage, and particularly relates to a full-immersion energy storage compartment based on partition overflow. BACKGROUND

[0002] At present, with the continuous improvement of energy consumption structure in China, the energy storage battery industry presents explosive development, and the safety and stability of the energy storage system are paid more and more attention. In the process of charging and discharging application of the energy storage battery, due to the existence of ohmic heat and polarization heat, a large amount of heat will be generated. If the heat cannot be diffused in time, it will be accumulated in the battery, which will increase the speed of the interface side reaction of the energy storage battery on the one hand, and the excessive accumulation of heat may cause the battery thermal runaway on the other hand. Therefore, efficient heat dissipation measures are a problem that must be considered in the design of the energy storage battery.

[0003] At present, the heat dissipation modes of the energy storage system mainly include air cooling and liquid cooling. Among them, the air cooling type mainly cools through air conditioning, the cooling medium is air, the energy efficiency ratio is low, the equipment occupies a large area, and the temperature consistency of the energy storage battery is poor. The liquid cooling adopts a cooling plate with water as the cooling medium, exchanges heat between the cooling medium flowing in the cooling plate and the energy storage battery, and the heat needs to be finally transmitted to the cooling medium through the battery shell and the cooling plate, and then the cooling medium dissipates the heat through the radiator. The heat transfer links are many, the thermal resistance is large, the heat exchange efficiency is low, and the performance requirement of the radiator is high.

[0004] In order to improve the heat dissipation performance of the energy storage system, the immersion type energy storage system with liquid medium immersed in the energy storage battery has been rapidly developed. The immersion type energy storage system immerses the energy storage battery in the liquid medium, and realizes heat dissipation by heat exchange between the liquid medium and the energy storage battery. However, the existing immersion type energy storage system mostly adopts the static immersion mode. After a long time of operation, the temperature of the liquid medium will gradually rise due to the gradual accumulation of heat in the liquid medium. SUMMARY

In the embodiment, the rear sealing gasket 205 is mounted on the rear sealing surface 204.

The front and rear sides of the middle energy storage area are respectively provided with a front immersion area 110 and a rear overflow area 120, and the left and right sides of the middle energy storage area are respectively provided with a left immersion area 130 and a right immersion area 140. 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, and the right immersion area 140 is located between the right side of the energy storage pack 10 and the sealing plate.

[0056] In the present embodiment, the sealing plate is sealingly connected with the lower sealing mounting rack 210 and the upper sealing mounting rack 230, so that the front immersion area 110, the rear overflow area 120, the left immersion area 130 and the right immersion area 140 can be limited around the mounting rack 200. By injecting the 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, the temperature of the energy storage pack 10 can be controlled, and the space occupation of 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 some embodiments, the overflow hole 213 is arranged on the rear flow channel baffle 231; in other embodiments, the overflow hole 213 is arranged on the lower sealing mounting frame 210. Specifically, the overflow hole 213 of this embodiment is arranged on the lower sealing mounting frame 210, and the overflow hole 213 is located on the lower support surface 211 between the rear flow channel baffle 231 and the rear side of the energy storage bag 10. By arranging the overflow hole 213, the temperature control medium in the energy storage bag 10 can enter the rear overflow area 120, thereby realizing the flow of the temperature control medium in the energy storage bag 10. In addition, in some embodiments, the overflow hole 21 can also be arranged on the energy storage bag 10, which will not be described again.
