Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a heat dissipation component for an energy storage battery switch. Background Art

[0002] The concept of energy storage battery switchgear is to centrally store electrical energy so that it can be used for power supply during peak power demand periods or in emergency situations. It is mainly composed of batteries, inverters and control systems. The battery is the core component of the energy storage cabinet, which can convert electrical energy into chemical energy and store it. The function of the inverter is to convert the stored DC power into AC power for use by various electrical equipment. The control system plays a role in management, optimization of energy utilization and protection of battery life.

[0003] When the energy storage battery switch cabinet is in operation, the temperature of its internal components will rise. If the temperature rise is too high, it will accelerate the aging of the components, causing the product insulation performance and reliability to decrease. Therefore, existing energy storage switch cabinets will be equipped with cooling fans to assist in the heat dissipation of its internal components.

[0004] The existing internal space planning of the energy storage battery switch cabinet will install some components in close contact with the side wall of the switch cabinet. When the cooling fan runs to accelerate the gas flow rate inside the switch cabinet and assist the internal components of the switch cabinet to dissipate heat, the gas flow rate on the side where some components are in contact with the side wall of the switch cabinet is slower, and the heat dissipation effect is poor, which will cause the local temperature of the components in contact with the side wall of the switch cabinet to be higher, thereby causing the components installed close to the side wall of the switch cabinet to have poor heat dissipation effect and faster aging.

A plurality of cabinet panels 1 are assembled to form a cabinet body. A heat dissipation fan 2 is installed at the upper end of the cabinet body. The cabinet body also includes a guide structure 3 for accelerating the gas flow rate outside the cabinet panel 1. The guide structure 3 is installed at the upper end of the cabinet body. The guide structure 3 includes a semi-enclosed pipe 301 fixedly embedded in the top of the cabinet body, and the heat dissipation fan 2 is fixedly installed inside the semi-enclosed pipe 301; a protective top cover 4 is used to protect the guide structure 3. The protective top cover 4 is fixedly installed at the upper end of the cabinet body.

[0025] Working principle for improving the heat dissipation effect of the switch cabinet: During the operation of the energy storage battery switch cabinet, the heat dissipation fan 2 runs to extract the gas inside the cabinet, which accelerates the gas flow rate inside the cabinet. The components attached to the side walls of the cabinet transfer the heat to the metal substrate 101 of the cabinet. The heat dissipation coating 103 on the outside of the metal substrate 101 then radiates the heat of the metal substrate 101 to the surrounding environment with lower temperature, so as to achieve the purpose of assisting the heat dissipation of the metal components close to the side walls of the cabinet, thereby improving the overall heat dissipation effect of the energy storage power switch cabinet.

[0026] Embodiment 2

The conduits 302 are fixedly installed on the upper end of the cabinet, and the conduits 302 are located on the upper side of the heat dissipation fan 2. The operation of the heat dissipation fan 2 can accelerate the gas flow rate inside the cabinet, and the conduits 302 and the semi-enclosed tube 301 are connected to each other.

[0028] See also Figure 2 The end of the conduit 1 302 away from the semi-enclosed tube 301 is fixedly connected to the conduit 2 303. The conduit 2 303 is fixedly installed on the outside of the cabinet and close to the upper end of the cabinet. The connection between the two conduits 2 303 is movable abutment. Both the conduit 1 302 and the conduit 2 303 are plastic tubes. The cost of the conduit 1 302 and the conduit 2 303 made of plastic is lower than that of metal tubes.

[0029] See also Figure 4 The lower end of the second conduit 303 is located outside the cabinet and is fixedly mounted with a plurality of conical air nozzles 304 that are equidistantly distributed.
