Flat-plate micro heat pipe array type solar air heat collection and storage integrated device

Abstract

The invention discloses a flat-plate micro heat pipe array type solar air heat collection and storage integrated device and relates to the technical field of heat exchange technologies and solar heating. A flat-plate micro heat pipe array assembly adopts a flat-plate type structure formed by multiple sealed micro heat pipes, and the micro heat pipes are filled with heat exchange media; the outside part of the flat-plate micro heat pipe array assembly is divided into a heat collection section, a heat storage section and a heat taking section respectively; the heat taking section is inserted into a heat taking air channel; the heat storage section of the flat-plate micro heat pipe array assembly is located in a heat accumulator box; a phase-change heat storage material is further sealed in the heat accumulator box; a black heat absorbing film is attached to the upper surface of the heat collection section and covered with a glass cover plate, a heat insulation material is attached to the lower surface of the heat collection section, a heat collector back plate is arranged below the heat insulation material, and a heat collector border frame frames side edges to prevent the side edges from being scattered. By means of the device, space can be saved, the system is simplified, the use time is prolonged, heat efficiency is improved, and heat loss is reduced.

Description

technical field [0001] The invention relates to the fields of heat exchange technology and solar energy heating technology, in particular to a set of novel solar air heat collection and heat storage integrated devices using air as the heat exchange medium. Background technique [0002] The shortage of energy, its low efficiency in the process of development and utilization, and the environmental pollution caused seriously restrict the sustainable development of my country's economy and society. However, in winter, the current heating and heating facilities in rural areas of our country are not yet complete, and the temperature difference between day and night is large. The heating method mostly uses biomass energy such as direct combustion of firewood and straw, or cheap but serious environmental pollution fossils such as honeycomb coal. Furnace heating is the main source of energy. Although this method has solved the heating problem in this area to a certain extent, the eff...

Problems solved by technology

[0004] In the solar system, the solar collector and the energy storage device need to be arranged separately, but it occupies a large space, the system is complex, and there is secondary heat exchange, and the overall thermal efficiency of the system is low. If the heat exchange loss can be reduced and the thermal efficiency can be improved, the solar system will be greatly improved
