Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage devices, and particularly relates to a communication base station energy storage device based on a boost battery. BACKGROUND

[0002] Traditional temperature control generally includes air cooling or liquid cooling. The air cooling utilizes thermal convection of thermodynamics, and temperature diffusion is accelerated by convection of different temperature differences and mechanical air supply to achieve cooling. The cooling has the disadvantage of slow temperature control, and especially for the fast temperature rise of the energy storage battery, the air cooling effect cannot meet the demand of fast temperature control, and the battery often operates at a higher temperature than the appropriate temperature, and the air cooling system is always in a high load operation state.

[0003] Another liquid cooling through refrigerant is to directly wrap the heat generating components through metal pipes to quickly absorb heat through heat transfer in thermodynamics. Compared with air cooling, the cooling effect and temperature control speed of liquid cooling are much better, but for lithium batteries, too low temperature will affect the charging efficiency, and liquid cooling needs to wrap the liquid cooling pipe around the battery to achieve uniform and rapid cooling effect, but this needs to manufacture very tight and complex liquid cooling pipes, and needs to be matched with a series of supporting processes such as mold opening, which will cause the cost to be very high, and if the order quantity of the energy storage device is not large, it may lead to loss, but if the liquid cooling pipe is only attached to one side of the battery, it is easy to cause a large temperature difference between the two ends of the battery, which affects the battery life and safety.

[0004] Therefore, based on the comprehensive influence of cost, heat conduction efficiency, safety of the battery and energy storage efficiency, the present application is proposed. SUMMARY

[0008] In an embodiment, the inner side wall of the energy storage cabinet is fixed with heat insulation sponge block, for reducing the influence of external temperature on the energy storage cabinet, improving the stability and accuracy of temperature control, compared with some open design, the closed design can make the battery better in a relatively constant temperature state, and the working load of the liquid cooling temperature control unit and the circulating turbine fan is also more stable, which is beneficial to improve the service life of the equipment.

[0009] In an embodiment, the aperture of the air suction port located on the left and right sides of the air suction disc is larger than the aperture of the air suction port located in the middle of the air suction disc, so that the air flow of the air suction port at each position close to and away from the circulating turbine fan is more balanced and uniform through the principle of air pressure, thereby improving the uniformity of overall temperature control in the energy storage cabinet.

[0010] In an embodiment, the air supply port provided on the air distribution disc is matched, and the aperture of the air supply port located on the two sides is larger than the aperture of the air supply port located in the middle.

[0011] In an embodiment, the cast hollow cooling plate is spaced apart and provided with several penetrating air passing ports, so that air can quickly pass through and form more contact area, which can improve the heat transfer efficiency of heat convection.

[0012] In an embodiment, a sealed independent second independent unit cavity is arranged below the first independent unit cavity in the energy storage cabinet, and a replaceable humidity control box is arranged in the second independent unit cavity, wherein the upper circulation pipe and the lower circulation pipe are communicated with the humidity control box and form a one-way air passage, and the humidity control box is filled with moisture absorbing particles for controlling the humidity of air in the energy storage cabinet.

[0013] In an embodiment, the air pressure regulator comprises two symmetrical gap control plates and a plurality of U-shaped thermal deformation bodies embedded in the middle of the gap control plates, the four edges of the gap between the gap control plates are sealed by elastic rubber sheets adhered to the side edges of the gap control plates, and the two ends of the U-shaped thermal deformation bodies are fixed to the inner side walls of the gap control plates. After the U-shaped thermal deformation bodies are heated and expanded, the gap between the gap control plates is expanded, thereby reducing the ventilation gap in the middle of the energy storage battery pack and increasing the air pressure and air speed at this position to improve the air heat convection cooling effect.

[0014] In an embodiment, the U-shaped thermal deformation body is made of silver-cadmium alloy.

[0015] The advantages and positive effects of the present application are:

[0016] The present application realizes the following advantages and positive effects by adopting the commonly used cast hollow cooling plate in the shape of a plate and the matching liquid cooling temperature control unit to introduce low-temperature refrigerant to the lower part of the energy storage battery pack, and then forming a heat convection cycle through the circulation turbine fan and the upper and lower circulation pipes, so that air is quickly cooled by passing through the cast hollow cooling plate and then forms a convection around the energy storage battery pack. Compared with traditional air cooling, the device can provide greater temperature difference heat convection, thereby transferring heat to the liquid cooling temperature control unit through the refrigerant and dissipating heat to the external air through the liquid cooling temperature control unit. The air in the energy storage cabinet is in internal circulation, which can improve the heat exchange efficiency and reduce the influence of external temperature on the energy storage battery pack, so that the temperature control components are more accurate.

[0017] And the humidity control box arranged in the internal circulation air passage dries the air to reduce the humidity and avoid its influence on the battery.

[0018] In addition, the air inlet disc and the air distribution disc are arranged with gradually changing hole diameters, so that the air flow rate at each position in the energy storage cabinet is uniform, and the structure is simple and reasonable.

[0019] In addition, the gap on the side of the energy storage battery pack is adjusted by the air pressure regulator arranged on the side of the integrated partition, and the principle is that when the temperature of a certain energy storage battery unit is high, the heat makes the U-shaped thermal deformation body expand, and the transverse thickness of the air pressure regulator is expanded, so that the gap on the left and right sides of the energy storage battery pack is reduced, the air pressure is increased, the flow rate is increased, and the cooling speed is improved;

[0020] The circulating air and the distributed modular cast hollow cooling plate in the application improve the cooling effect more uniformly, eliminate the disadvantage that the original air cooling device cools quickly near the air outlet and slowly far from the air outlet, and are more in line with the core demand of battery temperature control, that is, uniform temperature control.
