Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage cabinets, and specifically relates to a cabinet structure that takes into account both ventilation and heat dissipation of the energy storage cabinet and a high protection level. Background Art

[0002] The output characteristics of new energy are random and volatile due to the influence of the natural environment, making it difficult to provide regulation capabilities for the system. The power grid needs to adjust the grid according to the output power of the generator sets and the electricity demand to maintain stable operation at a frequency of 50Hz. The connection of a high proportion of renewable energy to the grid will further test the regulation capabilities of the power system.

[0003] In the traditional mode, power regulation usually relies on AGC frequency regulation units or peak regulation units, while the application of energy storage can liberate traditional units, allowing them to maintain their rated working conditions more often, thereby reducing losses, reducing carbon emissions, and improving the utilization efficiency of traditional units. At the same time, it can smooth out the contradiction between power supply and demand, and absorb wind and solar power abandonment. Energy storage technology will play a more important role in the future energy production end.

[0004] However, because the existing liquid-cooled industrial and commercial energy storage cabinets are installed outdoors, the energy storage cabinet is required to have a rain and dustproof level of IP55. At the same time, the liquid cooling unit and PCS inside the energy storage cabinet have barrier-free ventilation and heat dissipation requirements. Utility Model Content

[0005] In order to solve the above problems, this paper proposes a cabinet structure that takes into account both ventilation and heat dissipation of the energy storage cabinet and a high protection level. A front door panel is provided on the outside of the front side of the main box of the energy storage cabinet, and an air inlet channel is provided between the front side of the main box and the front door panel. Sealing strips are provided on the surfaces of both ends of the air inlet channel, and a drain pipe is provided on the bottom surface of the air inlet channel. An air inlet is provided at a surface connected to the main box on one side of the air inlet channel, and a door panel grid is provided at a surface connected to the front door panel on the other side of the air inlet channel. An air outlet is provided on the other side of the main box opposite to the air inlet, and a number of exhaust fans are provided on the inner side of the air outlet. The air inlet channel can meet the barrier-free ventilation requirements of the liquid cooling unit and the IP55 protection level of the entire cabinet, and the air suction form can better prevent foreign matter, dust and liquid from entering the interior of the box, and the drain pipe provided at the bottom of the air inlet channel can also prevent the liquid entering from the door panel mesh of the front door panel from being quickly discharged.

[0006] The main box body is in the shape of a vertical rectangular box body. The air inlet and the air outlet on the front and rear sides of the main box body are provided with panel openings. Both sides of the panel openings are provided with a plurality of hook holes. The outer sides of the panel openings are provided with grid plates. Both sides of the grid plates are provided with a plurality of hooks. The grid plates are connected to the main box body through the hooks and the hook holes. The interior of the existing energy storage cabinet is modified through the hooks, which is convenient for quick disassembly and installation and reduces the production cost of the box body.

[0007] A number of fan mounting brackets are provided on the inner surface of the grid plate outside the air outlet, and the fan mounting bracket is arranged on the inner side of the main box body. An exhaust fan is embedded on the inner side of the fan mounting bracket. One side of the exhaust fan is for suction, and the other side of the exhaust fan is for outlet. The suction side of the exhaust fan faces the inner side of the main box body, and the outlet side of the exhaust fan faces the outer side of the box body. By arranging an exhaust fan for suction at the air outlet, a negative pressure suction state is achieved inside the box body. This form can minimize the entry of dust and liquid and improve the airtightness of the box body.

[0008] The door panel grid and the air inlet are of the same size and are both located on the inner contour side of the air inlet channel. The air inlet channel is in the shape of a rectangular double-pass pipe and is made of a thermal conductive material. The temperature of the energy storage cabinet is conducted to the surface of the air inlet channel through the thermal conductive air inlet channel, thereby condensing moisture in the inhaled air onto the inner surface of the air inlet channel through the air inlet channel having a certain temperature, thereby improving the moisture-proof performance of the interior of the cabinet.

[0009] The drain pipe is made of a rubber hose, and is connected to the inner side of the air inlet channel through the bottom surface of the air inlet channel, so that the liquid inside the air inlet duct can be quickly discharged through the drain pipe.

[0010] Beneficial effects:

[0011] The air inlet channel can not only meet the barrier-free ventilation requirements of the liquid cooling unit, but also meet the IP55 protection level requirement of the entire cabinet. The air suction form can better prevent foreign matter, dust and liquid from entering the box body, and the drain pipe at the bottom of the air inlet channel can also prevent the liquid entering from the door panel mesh of the front door panel from being quickly discharged.

[0012] The interior of the existing energy storage cabinet is modified by hooking, which facilitates quick disassembly and installation and reduces the production cost of the cabinet.

[0013] By setting an exhaust fan for suction at the air outlet, a negative pressure suction state can be achieved inside the box. This form can minimize the entry of dust and liquid and improve the airtightness of the box.

[0014] The temperature of the energy storage cabinet is conducted to the surface of the air inlet channel through the temperature-conducting air inlet channel, so that the moisture in the inhaled air is condensed onto the inner surface of the air inlet channel through the air inlet channel with a certain temperature, thereby improving the moisture-proof performance of the interior of the cabinet.
