Solar medium temperature heat collector, and preparing method and using method thereof

Abstract

The invention discloses a solar medium temperature heat collector, and further discloses a method for preparing the solar medium temperature heat collector, and a using method of the solar medium temperature heat collector. The solar medium temperature heat collector comprises a heat collector body; the heat collector body comprises a steam generating unit and an eccentric vacuum tube; a row of circular hole structures is formed in a steam main tube, the circular hole structures are composed of circular holes and flanging structures, the flanging structures are downwards bent by the steam maintube located at the circular holes, and the circular hole structures are each in a cylindrical shape; one end of a steam branch tube is welded to the flanging structures of the steam main tube, and the steam branch tube is a thin-walled metal tube; one end of the steam branch tube communicates with the steal main tube, two rows of circular hole structures are arranged at the upper end and the lower end of a water main tube, and the circular hole structures located on the water main tube correspond to the circular hole structures located on the steam main tube; and the water main tube is a thin-walled metal tube. The solar medium temperature heat collector has the advantages of stable and reasonable structure, low energy consumption and high heat collecting efficiency.

[0003] In response to the challenges of global climate change, resource and energy shortages, and the deterioration of the ecological environment, human beings are following the model of low-carbon recycling, with low-carbon orientation, developing circular economy, building low-carbon ecological cities, and popularizing low-carbon green buildings. Green building refers to a building that is harmless to the environment, can make full use of the environment and natural resources, and is built without destroying the basic ecological balance of the environment. It can also be called a sustainable development building, an ecological building, and a return to nature. Buildings, energy-saving and environmentally friendly buildings, etc. However, in order to meet the living needs of constant temperature, constant humidity, and constant oxygen, the existing green buildings mostly use coal-fired heating, which wastes a lot of conventional energy and is not environmentally friendly.

[0004] Existing solar collectors cannot bear high pressure, and the gas main pipe and water main pipe are prone to stress deformation to distortion or cracks when welding and connecting the gas branch pipes and water branch pipes. The processing yield is low, the scrap rate is high, and the cost is high. less efficient heat output
