The working principle of the energy storage cabinet is that in a power system, the energy storage cabinet can release stored energy when needed so as to balance the voltage and frequency of a power grid. The energy storage cabinet is generally composed of an energy storage device, a converter and a control system, and has the capability of absorbing and releasing energy. The energy storage cabinet mainly converts electric energy into energy of another form through the energy storage device and stores the energy, then converts the energy into electric energy through the converter when needed, and transmits the electric energy to needed electric equipment through a power grid.
For lithium ion batteries as a medium for storing energy of a power grid, generally, battery monomers are required to be assembled into a battery module, then the battery module is fixed on a certain bracket or in a cabinet through regular arrangement, and a plurality of brackets or cabinets are arranged in a modularized space of a fixed box body, so that the problem that the cooling effect is poor easily occurs when the battery module is cooled in the limited space.
In addition, in order to avoid the reduction of the performance and efficiency of the energy storage cabinet or the shortening of the service life of the battery, the temperature in the energy storage cabinet needs to be controlled so as to improve the service performance of the energy storage cabinet and prolong the service life of the energy storage cabinet. However, in the prior art, the temperature control structure of the energy storage cabinet is generally provided with only one air cooling machine for cooling, or provided with the ventilation holes and the electric fan, so that the problems of uneven temperature distribution, inaccurate temperature control, low heat exchange efficiency and the like exist, and if the temperature control of the batteries in the energy storage cabinet is uneven, the performance among the batteries in the energy storage cabinet can be different for a long time.
For example, patent, "a modular lithium ion battery energy storage cabinet" (publication number: CN 218731490U) describes: the cabinet body includes epitheca, well shell and inferior valve, and epitheca and inferior valve can dismantle respectively and peg graft in the upper and lower both ends of well shell, and the both sides of epitheca all are provided with radiator unit, one side of the cabinet body is provided with the cabinet door, the mounting panel is all installed through the bolt to the inner wall both sides of the cabinet body, two sets of a plurality of groups standing grooves have all been seted up to the opposite one side of mounting panel, two sets of peg graft through the standing groove between the mounting panel has two sets of boards of placing. The heat dissipation assembly comprises a box body, wherein the box body is fixedly embedded on one side wall of the upper shell, and two groups of heat dissipation fans are symmetrically arranged in the box body. In the patent, two groups of fans are arranged for cooling, and if the battery temperature is high or the outdoor temperature is high, the heat dissipation effect is poor.
For example, patent "a lithium ion battery energy storage cabinet convenient and quick to overhaul" (publication number: CN 219610598U) describes: the bottom of the cabinet body is provided with a channel steel base, and the top of the cabinet body 1 is provided with a fan radiating device. The patent only adopts a fan to dissipate heat, and the heat dissipation temperature is not uniform.
For example, patent "an energy storage cabinet capable of independent heat dissipation" (publication number: CN 217823091U) describes: the cabinet body one side is provided with the box, and the box inside is provided with the air-cooler, and the box surface is provided with the air vent, when the air-cooler starts, ventilates through the air vent.
