Abstract

The invention provides a solar flat-plate heat collector. The solar flat-plate heat collector comprises a soft film, a backboard and a flow guide pipe; the soft film is arranged on the outer side face of the backboard and used for absorbing solar energy, the edge of the soft film is connected with the edge of the backboard in a sealed manner, and a gap is formed between the soft film and the outer side face of the backboard; the top of the soft film or the backboard is provided with a liquid inlet, and the bottom of the soft film or the backboard is provided with a liquid outlet; the flow guide pipe is transversely arranged on the upper portion of the gap and communicates with the liquid inlet, and the side wall of the flow guide pipe is provided with an overflowing hole; and the liquid inlet, the flow guide pipe, the overflowing hole, the gap and the liquid outlet form a channel allowing a heat transfer working medium to circulate, and the heat transfer working medium forms a water film in the gap and performs heat transfer with the soft film. The uniformly-thin water film is formed in the gap between the soft film and the backboard through the heat transfer working medium, the heat collection area is increased, the surface heat loss is lowered, and heat collection efficiency is improved; and meanwhile, a circulating pipe does not need to be arranged, the heat transfer working medium is circulated in the gap, and the situation that when the heat collector is started, air resistance is formed due to discordance between water and gas, and circulation of the heat transfer working medium is blocked is avoided.

Description

technical field [0001] The invention relates to the technical field of solar heat exchange equipment, in particular to a solar flat panel heat collector. Background technique [0002] Energy is the driving force of social and economic development. The relative shortage of energy, the low efficiency in the process of energy development and utilization, and the resulting environmental pollution are becoming important constraints to the sustainable development of my country's economy and society. It is imminent to develop clean and sustainable energy. As one of the new energy sources, solar energy has two advantages: one is abundant, inexhaustible, and inexhaustible; the other is safe and clean, and will not threaten human beings or damage the environment. [0003] The solar collector is a key device for utilizing solar radiant energy, which realizes the conversion of solar radiant energy into thermal energy and transfers it to the thermal working medium. Common solar collecto...
