The utility model discloses a submarine cable J-shaped pipe ventilation cooling automatic control device comprising a submarine cable J-shaped pipe air section structure, and a J-shaped pipe of the submarine cable J-shaped pipe air section structure is uniformly provided with four groups of ventilation structures with the same structure along the circumferential direction. The four ventilation structures are further connected with a ventilation opening automatic control device arranged in the submarine cable J-shaped pipe air section structure, the ventilation opening automatic control device is further connected with a transmission device installed on an offshore booster station platform, and the transmission device is further connected with a meteorological sensor installed on the offshore booster station platform in a wireless connection mode. According to the utility model, a good ventilation cooling effect of the submarine cable J-shaped pipe air section is realized.

The present application relates to a new ventilation structure for BIPV module, comprising a photovoltaic assembly matched with a building wall, the back of the photovoltaic assembly is installed on the facade of the building wall in parallel through a plurality of steel columns, a ventilation gap is formed between the photovoltaic assembly and the building wall, the bottom of the ventilation gap is transversely inserted with an air inlet channel for constituting a contraction air inlet, and the top is longitudinally inserted with an exhaust chimney as an air outlet. The present application modifies the air duct between the photovoltaic assembly and the building wall in a simple way, so that the natural convection in the ventilation gap can be accelerated to a high wind speed level similar to the forced convection condition, without any mechanical fan device, and the ventilation cooling of the BIPV module can be enhanced without increasing the power consumption. In addition, the improved ventilation structure of the present application can be easily realized without a large amount of installation work, and the related fixed cost is far lower than the modification of a single solar panel.
