Description
Technical Field
The utility model relates to the technical field of heat dissipation of energy storage converters, in particular to an energy storage converter convenient for heat dissipation.
Background
In the field of energy sources today, an energy storage converter plays a vital role as one of the key devices. With the increasing demand for energy storage and the large-scale access of renewable energy sources to the power grid, the performance and reliability of energy storage converters are becoming more and more of an issue.
In the working process of the energy storage converter, a large amount of heat can be generated due to the fact that the internal electronic elements continuously convert and control electric energy. If not effectively dissipated, the heat can have various adverse effects on the performance of the energy storage converter. First, excessive temperatures may cause performance degradation of electronic components, such as increased resistance, reduced capacitance, etc., thereby affecting the conversion efficiency and stability of the energy storage converter. Secondly, the service life of the electronic element is greatly shortened when the electronic element is in a high-temperature environment for a long time, and the maintenance cost and the replacement frequency of the equipment are increased. In addition, excessive temperatures may also raise safety concerns, such as overheating may cause dangerous conditions of fire, explosion, etc. of the component.
At present, the existing heat dissipation modes of the energy storage converter mainly comprise natural heat dissipation, air cooling heat dissipation and liquid cooling heat dissipation. The natural heat dissipation is realized by means of heat conduction of the equipment and heat exchange with surrounding air, so that the heat dissipation effect is limited, and the heat dissipation requirement of the high-power energy storage converter is difficult to meet. The air-cooled heat dissipation blows external cold air into the equipment through the fan to take away heat, but the mode is easily influenced by environmental factors such as dust, humidity and the like, and meanwhile, the independent fan dissipates heat, so that the heat dissipation effect is poor. Liquid cooling heat dissipation is better, but system structure is complicated, and the cost is higher, and there is the risk that coolant liquid leaks.
In summary, the existing heat dissipation method of the energy storage converter has the problems of poor heat dissipation effect, complex structure, high cost and large influence by environmental factors, so that a novel energy storage converter convenient for heat dissipation is urgently needed to meet the increasing energy storage and conversion demands.
