Improved structure to enhance ventilation and heat dissipation of the enclosure

Abstract

This invention relates to an improved structure for enhancing ventilation and heat dissipation in enclosures, addressing the issue of accumulated heat from enclosed environments, direct sunlight, or power conversion equipment. The core mechanism involves a temperature sensor detecting the temperature of the enclosure. When the temperature exceeds 50 degrees Celsius, the controller simultaneously activates the top ventilation fan to expel hot air and drives the bottom adjustable louvers to introduce cool external air, achieving efficient heat dissipation through active airflow regulation. Furthermore, the structure incorporates a permanent ventilation fan, permanently open louvers, and a protective cover, which not only maintains basic ventilation at low temperatures but also effectively prevents rainwater and dust intrusion, ensuring stable operation of the power conversion equipment in a safe and well-ventilated environment.
