Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel inverter maintenance, and more specifically, to a photovoltaic panel inverter heat dissipation duct detection device. Background Art

[0002] A photovoltaic inverter, also known as a power conditioner, converts the variable DC voltage generated by photovoltaic solar panels into AC power at mains frequency. It is a key component in the balance of a photovoltaic array system. Composed of a boost circuit and an inverter bridge circuit, a photovoltaic inverter can be used in commercial power transmission systems and off-grid power grids. Primarily composed of switching elements such as transistors, they convert DC input into AC output through repeated on-off switching. PV inverters offer features such as automatic start and stop, tracking control, and protection against independent operation.

[0003] During the operation of a photovoltaic inverter, its internal components generate a certain amount of heat. When this heat accumulates to a certain level, it will reduce the performance of the entire photovoltaic inverter and easily cause damage to the components. Therefore, a heat dissipation structure is an essential structure in photovoltaic inverters. The heat dissipation structure usually includes various heat dissipation windows, and the heat dissipation windows may also be equipped with active air flow fans. Through air flow, the air inside and outside the photovoltaic inverter housing is exchanged, thereby dissipating internal heat.

[0004] However, during the actual operation of photovoltaic inverters, abnormal heat dissipation often occurs, usually due to blockage of the cooling duct or failure of the cooling fan. If not discovered in time, the photovoltaic inverter will be allowed to operate for a long time without smooth heat dissipation, which will likely cause damage to the entire device and be detrimental to actual electric field operation. Therefore, it is necessary to design a heat dissipation duct detection device to detect the heat dissipation structure of photovoltaic inverters. Utility Model Content
