Embodiment Construction

[0043] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] figure 1 A solar heat collector system is shown, the system includes a heat collector 1 and a heat utilization device 2 thereof, and the heat collector 1 and the heat utilization device 2 are connected by pipelines.

[0045] The structure of the collector is as figure 2 As shown, it includes a heat collecting tube 12 and a reflector 11, and the heat collecting tube 12 is a flat tube. Such as image 3As shown, the lower flat surface of the flat tube is opposite to the reflective surface of the reflector 11, and the focus of the reflector 11 is located between the upper flat surface and the lower flat surface, preferably on the upper flat surface of the flat tube 12 along the length The axis of the direction and the lower flat surface are along the plane where the axis of the length direction is located.

[0046] Such as Figure 3-7...

Abstract

The invention provides a solar system, a heating and ventilating system and a building roof with the solar system. The solar system comprises a collector. The collector comprises heat collecting pipesand a reflecting mirror. The heat collecting pipes are flat pipes. The lower flat surfaces of the flat pipes are opposite to the reflecting surface of the reflecting mirror. Each flat pipe comprise abottom plate on the lower side and an upper cover on the upper side, wherein the upper cover and the bottom plate are assembled together to form a cavity of the flat pipe, and fluid flows in the cavity. Each bottom plate comprises a plurality of heat exchange area. Each heat exchange area comprises vertical plates and column ribs. The novel solar system is developed, and a flow guide structure isarranged in a cold plate of each heat exchange area, so that a refrigerant flowing dead area is effectively reduced, and the thermal homogeneity of a hot flow surface is further improved; and by means of the column ribs, the disturbance to the flow field is enhanced, the heat exchange area is expanded, and heat exchange can be easily reinforced.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a solar energy system, a heating and ventilation system and a building roof thereof. Background technique [0002] With the continuous development of the economy and the massive consumption of energy, energy conservation has become a topic of global concern. Renewable energy such as solar energy, wind energy, and geothermal energy, and the utilization of industrial waste heat and waste heat have become the focus of research and development in various countries. However, these energy sources have Due to the characteristics of discontinuity and instability, the research on energy storage technology is particularly important. Heat storage technology is one of energy storage technologies, and an important part of heat storage technology is the design of phase change heat storage heat exchanger. The common phase change regenerative heat exchanger consists of two tube...
