Ventilation cavity heat dissipation system of roof photovoltaic panel
The invention discloses a ventilation cavity heat dissipation system of a roof photovoltaic panel. The system comprises a base plate, a bearing plate, a connecting plate, a photovoltaic module, a ventilation cavity composed of the above structures and the like; the photovoltaic module is fixed to the bearing plate through a pressing block, a locking mechanism or a connecting bolt; the connecting plate is connected with the bearing plate and the base plate; the connecting plate inclines towards the outer side or is perpendicular to the base plate; and the base plate is provided with a spherical bulge structure. According to the ventilation cavity heat dissipation system of the roof photovoltaic panel, the turbulence degree of air flowing in the roof photovoltaic ventilation cavity is enhanced through a heat exchange enhancing structure, air convective heat transfer in the ventilation cavity is enhanced, and then the working temperature of an assembly is reduced, so that the power generation efficiency of a roof photovoltaic system is improved, the structural size of the ventilation cavity can be further reduced on the premise of ensuring heat dissipation of the ventilation cavity, and therefore, the construction cost of a roof photovoltaic project is reduced.
本发明的一种屋顶光伏板的通风腔散热系统，包括基板、承载板、连接板、光伏组件，以及由上述结构组成的通风腔等，所述光伏组件通过压块、锁扣机构或连接螺栓固定于承载板上；所述连接板连接承载板与基板，连接板向外侧倾斜或垂直于基板；所述基板具有球形凸起结构；该系统通过加强换热的结构增强屋顶光伏通风腔内空气流动的湍动度，强化通风腔内空气对流传热，进而降低组件工作温度，从而提升屋顶光伏系统的发电效率，在保证通风腔散热的前提下，可以进一步减小通风腔的结构尺寸，从而降低屋顶光伏项目的工程造价。
