Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage equipment technology, specifically to an immersion liquid-cooled energy storage device. Background Technology
[0002] With the widespread application of new energy sources, energy storage devices have become key equipment for power storage and distribution. Currently, traditional energy storage devices mostly employ air cooling or pipe-type liquid cooling methods. Air-cooled energy storage devices rely on air convection for heat dissipation, resulting in low heat dissipation efficiency. During prolonged high-load operation, the heat cannot be dissipated in time, leading to excessively high internal temperatures and severely impacting the performance and lifespan of the energy storage components. While pipe-type liquid-cooled energy storage devices offer improved heat dissipation compared to air cooling, the coolant only indirectly contacts the energy storage components through pipes, limiting the heat exchange area and resulting in still unsatisfactory heat dissipation. Moreover, the pipe structure is complex, and the pipes are prone to blockages and leaks, making repairs difficult and costly. Therefore, there is an urgent need for a novel, highly efficient, and easy-to-maintain immersion liquid-cooled energy storage device to address the problems of existing technologies. Utility Model Content
[0003] The purpose of this utility model is to provide an immersion liquid-cooled energy storage device to solve the problem mentioned in the background art that most traditional energy storage devices currently use air cooling or pipeline liquid cooling heat dissipation methods. Air-cooled energy storage devices rely on air convection for heat dissipation, which has low heat dissipation efficiency. Although pipeline liquid-cooled energy storage devices have a better heat dissipation effect than air cooling, the coolant only indirectly contacts the energy storage element through the pipeline, resulting in a limited heat exchange area and still unsatisfactory heat dissipation effect.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an immersion liquid-cooled energy storage device, comprising an energy storage device housing, the energy storage device housing being filled with coolant, a fixed frame arranged in a matrix inside the energy storage device housing, the fixed frame having multiple mounting holes, a coolant circulation inlet at the bottom of the energy storage device housing, a coolant circulation outlet on the side near the top, a baffle fixedly installed below the energy storage device housing, a baffle propeller rotatably installed at the bottom of the energy storage device housing, a driver for driving the baffle propeller to rotate inside the baffle, a cover at the top of the energy storage device housing, and an observation window on the inner side of the cover.
[0005] By using the above technical solution, the energy storage element is completely immersed in the coolant. Combined with the baffle to control the rotation of the baffle, the contact area and heat exchange efficiency between the coolant and the energy storage element are greatly increased. Compared with traditional energy storage devices, the heat dissipation effect is significantly improved, which can effectively reduce the internal temperature of the energy storage device, ensure the stable operation of the energy storage element, and extend the service life of the energy storage device.

[0007] Through the above technical solution, the insulating and thermally conductive material not only ensures the insulation between energy storage components, but also assists in heat conduction, while the elastic insulating gasket further stabilizes the energy storage components.
[0008] In a preferred embodiment, the present invention can be further configured such that the driver includes a motor, a reducer, and a PLC controller.

[0010] Through the above technical solutions, the filter screen can effectively prevent impurities from damaging the energy storage components and internal structure.
[0011] In a preferred embodiment, the present invention can be further configured such that: a support foot is provided at the bottom of the energy storage housing, and an anti-slip rubber pad is provided at the bottom of the support foot.
[0012] Through the above technical solutions, the anti-slip rubber pads make the energy storage device more stable during placement and use.
