Description

Technical Field

[0001] The utility model relates to the field of inverter equipment, in particular to a heat dissipation structure of a PCS energy storage inverter. Background Art

[0002] An inverter is a power conversion device that can convert direct current into alternating current. It consists of an inverter bridge, control logic, and filter circuits. It can convert 12V or 24V direct current into 230V, 50Hz alternating current or other types of alternating current. Inverters are widely used in various fields, such as air conditioning, fans, and lighting. Some inverters use PCS energy storage technology. This inverter can control the charging and discharging process of the battery and perform AC / DC conversion. In the absence of a power grid, PCS can directly supply power to the AC load. The PCS controller receives background control instructions through communication, and controls the inverter to charge or discharge the battery according to the sign and size of the power instruction, so as to adjust the active power and reactive power of the power grid. When the inverter is running, the internal semiconductor devices will emit heat. If the heat cannot be dissipated in time, the temperature of the inverter will rise, resulting in a decrease in its performance, a shortened life, and even possible failure. Therefore, a heat dissipation mechanism is set inside the inverter housing of the inverter to discharge the heat inside the radiator and ensure the normal operation of the inverter.

[0003] The heat dissipation mechanism of the inverter is basically composed of a heat sink and fixing bolts. The heat sink is set inside the inverter housing of the inverter, the bottom of the heat sink extends out of the inverter housing, and the heat sink is fixed by the fixing bolts. Through this design, the heat inside the inverter is exported out of the inverter to ensure the normal operation of the inverter. However, when the heat sink is damaged or deformed, the staff needs to disassemble it for maintenance, because there are many electronic components inside, and the gap between the top of the heat sink and the inverter housing is small, the staff has little manual movement space inside it, and it is inconvenient to disassemble, which reduces the maintenance efficiency of the staff to a certain extent.
