The power supply of the fan is a solar photovoltaic power generating board at inner side at front of the panel. The panel is a flat glass. Between the panel and the back board, the rim is connected. On the rim, some concave ports for connecting are provided. In the inner cavity enclosed by the panel, back board and the rim, a corrugated heat-absorbing board is fixedly connected on the inner bottom side of the shallow box-like heat-preservation sandwich board. The outer surface of the corrugated heat-absorbing board is provided with a heat-absorbing coating. The inner wall of the corrugated heat-absorbing board is connected with heat-exchanging fins. The inside of the corrugated heat-absorbing board forms a heat-exchanging cavity, which is communicated with the air inlet and the air outlet. The invention greatly reduces the cost of the wall board integrating solar with a building, is easy to maintain, improves the service life and is easy to spread and apply in large area.

The invention relates to a heat exchanger structure, comprising a heat exchanger casing and a combustion chamber, wherein the peripheral face of the combustion chamber is provided with a plurality of positioning bosses which are fixed with an inner wall of the heat exchanger casing; and heat transfer medium passages are formed between adjacent positioning bosses and are spirally shaped along the axis of the combustion chamber. In the heat exchanger structure, the heat transfer medium passages are formed between adjacent positioning bosses and are spirally shaped along the axis of the combustion chamber; the positioning bosses are fixed in a sealing manner with the inner wall of the heat exchanger casing; heat energy inside a cavity of the combustion chamber can achieve direct heat exchange with heat transfer media, thus the efficiency of heat exchange is enhanced; the heat absorption area of the media is enlarged, the heat conversion efficiency is enhanced, the number of laminar flow layer decreases, the number of turbulent flow layer increases and the heat conversion coefficient is raised; and simultaneously, the particles inside the heat transfer medium passages are hardly deposited and scale-formed, the maintenance times is reduced, the service life is prolonged and the using cost is lowered.
