Description

Technical Field

[0001] The present invention relates to the technical field of energy storage converters, and in particular to an energy storage converter with high-efficiency heat dissipation. Background Art

[0002] The energy storage inverter can control the charging and discharging process of the battery and perform AC / DC conversion. It can directly supply power to the AC load in the absence of a power grid. The energy storage inverter is composed of a bidirectional inverter, a control unit, etc. The energy storage inverter 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, thereby realizing the regulation of the active power and reactive power of the power grid.

[0003] There are a large number of heat-generating devices in the energy storage converter. Overheating inside the energy storage converter will affect the stability of the entire device operation. Therefore, it is necessary to cool the energy storage converter while it is working.

[0004] The prior art patent document with publication number CN218300712U provides an energy storage converter with high efficiency in heat dissipation. The energy storage converter is provided with a cabinet on a base, a cabinet door is provided on one side of the cabinet, a control panel is provided on the cabinet door, a partition with a support plate is provided inside the cabinet, a heat dissipation gap is provided on the partition, a temperature sensor is installed on the inner wall of the cabinet, a heat dissipation mechanism including a cold air fan is provided on both sides of the cabinet, an air outlet duct at an air outlet end of the cold air fan is connected to the bottom of the inner cavity of the cabinet, a temperature sensor signal is connected to the control panel, and the cold air fan is electrically connected to the control panel. When in use, the start temperature and the stop temperature are set through the control panel. When the temperature inside the cabinet is higher than the set start temperature, the temperature sensor transmits a signal to the control panel, and the control panel controls the cold air fan to start and dissipate heat and cool down the inside of the cabinet. When the temperature inside the cabinet is lower than the stop temperature, the cold air fan is stopped. Through the cooperation of the control panel, the temperature sensor and the cold air fan, the heat dissipation mechanism can be flexibly started and stopped according to the temperature inside the cabinet, thereby avoiding the problem of energy waste caused by the continuous operation of the cold air fan, and having high practical value.

[0005] In the above-mentioned prior art, although the energy storage inverter can flexibly start and stop the heat dissipation mechanism according to the temperature inside the cabinet through the cooperation of the control panel, the temperature sensor and the air cooler, thereby avoiding the problem of energy waste caused by the continuous operation of the air cooler, the heat dissipation mechanism in the patented technology cools the internal equipment by inputting cold air at the bottom of the equipment, and can only cool one point of the equipment. The heat dissipation efficiency is insufficient, and the energy storage inverter cannot be cooled in all directions, which reduces the heat dissipation effect. Therefore, we need an energy storage inverter with efficient heat dissipation. Summary of the invention
