Abstract

The invention provides a direct wallboard radiation heating system employing buried gravity heat pipes. The heating system comprises multiple groups of buried gravity heat pipe radiating units, wherein each radiating unit comprises condensation segments, a heat transport segment, an evaporation segment, a liquid injection opening and a phase change liquid; each radiating unit is provided with two or three condensation segments and is welded to a horizontal mother pipe; the horizontal mother pipe is connected with the heat transport segment through a tee joint; and the liquid injection opening is welded to one end of the horizontal mother pipe. The direct wallboard radiation heating system has the effects that conventional energy consumption can be partially or completely replaced in heating energy consumption of buildings, and 20-40% of energy conservation can be achieved through partial placement. By using automatic one-way heat transfer characteristics of the gravity heat pipes, a moving component is avoided and manual operation is not needed during operation, so that the system almost has no operation cost. The system provided by the invention is suitable for a standby heating system of an industrial building, and has the advantages of being energy-saving, and free of operation cost.

Description

technical field [0001] The invention relates to the field of geothermal heating, in particular to an underground gravity heat pipe direct wall panel radiation heating system. Background technique [0002] At present, the existing heating technology still mainly relies on conventional energy, but the consumption of conventional energy has aggravated environmental pollution and caused many problems. Therefore, rational use of new energy such as geothermal energy is an inevitable choice. [0003] The heating system at the present stage is to meet the requirements of human comfort, without considering the suitable low temperature heating situation. Directly using the existing heating system for low-temperature heating will increase the hydraulic imbalance of the heating system, increase the difficulty of adjusting the entire heating system, increase the energy consumption of operation, and violate the goal of saving energy and reducing consumption of the whole society. [0004...
