A photovoltaic power generation system sensor protection structure

Abstract

This utility model belongs to the field of photovoltaic power generation system technology, and discloses a sensor protection structure for a photovoltaic power generation system. It includes a housing, a buffer base, and a humidity sensor. The synergistic effect of the thermally conductive silicone pad, honeycomb heat dissipation holes, and waterproof and breathable membrane ensures a directional heat conduction path for the entire protection mechanism: sensor heat → thermally conductive silicone pad → housing shell → external air convection + accelerated heat dissipation through honeycomb holes. This mechanism solves the problem of incompatibility between protection and heat dissipation, preventing sensor drift due to high temperatures. The humidity sensor detects the humidity inside the device. When the humidity exceeds a certain threshold, the heating element is activated, causing the temperature of the buffer base to rise and forcibly evaporate water vapor, which then flows out through the honeycomb heat dissipation holes. Furthermore, the humidity sensor and heating element are directly powered by the photovoltaic system, consuming energy only during triggering and having no additional power consumption during normal operation, thus improving sensor durability.
