Description

technical field [0001] The invention relates to a solar heat pipe heat collection and heat storage floor radiation heating system, which belongs to the solar energy utilization technology. Background technique [0002] Gravity heat pipe, referred to as "two-phase closed thermosiphon", is an efficient heat transfer element. When the heat pipe is working, the evaporating section absorbs heat, and the working fluid absorbs the heat from the tube wall to increase the temperature; when the temperature is higher than the saturated liquid temperature, it is vaporized, and the pressure also increases; the vapor generated by gasification flows to the condensate with lower pressure. In the condensation section, cooled by the medium outside the tube, it condenses into a liquid and releases latent heat; the condensed liquid returns to the evaporation section under the action of gravity, so that the cycle goes back and forth to realize the transfer and transfer of energy. Heat pipes use...

Problems solved by technology

[0005] In view of the cold indoors in the Yangtze River Delta region in winter, there is no central heating, and most buildings use distributed energy-consuming equipment such as electric heating. However, this traditional heating method has problems such as discomfort, unhygienic, and high cost. The purpose of this invention is to propose a A solar heat pipe heat collection and heat storage floor radiant heating system, using solar energy, combined with the technical means of heat pipe efficient heat conduction, heat collection and heat storage, to achieve zero-energy heating for buildings, so as to achieve energy saving, environmental protection, and energy consumption reduction effects
