Air and water integrated solar collector based on miniature heat pipe technique

Abstract

The invention provides an air and water integrated solar collector based on a miniature heat pipe technique. The air and water integrated solar collector comprises a flat plate collector, a heat exchanger and a miniature heat pipe array, wherein the upper end of the flat plate collector is connected with the lower end of the heat exchanger, and the miniature heat pipe array penetrates through theflat plate collector and the heat exchanger; the flat plate collector comprises a glass cover and an insulation board, the glass cover is arranged on the upper part of the insulation board and forms asealing interlayer together with the insulation board, and the evaporation section of the miniature heat pipe array is located in the sealing interlayer; and the heat exchanger comprises a heat exchange air channel and a heat exchange water pipe, the condensation section of the miniature heat pipe array is located in the heat exchange air channel, and the heat exchange water pipe is attached to the surface of the condensation section of the miniature heat pipe array. According to the air and water integrated solar collector, solar energy is fully used for heating air and water at the same time, so that the integration of air and water heating is realized, the energy waste is reduced, and the energy utilization rate is high.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to an air-water integrated solar heat collector based on micro heat pipe technology. Background technique [0002] In today's world, conventional energy is increasingly scarce, and solar energy, as a renewable and non-polluting new energy, is gradually being valued. Solar collectors are the most mature and widely used solar energy utilization. At present, solar collectors for heating are mainly divided into two forms: vacuum tube solar collectors and flat-plate solar collectors. Although the vacuum tube solar collector has the advantages of good antifreeze and frost resistance and small heat loss coefficient, and the flat plate solar collector has the advantages of high thermal efficiency, there are many problems in the existing solar collectors, such as, The vacuum tube of the evacuated tube solar collector has problems such as water leakage, damage, and repair, and the flat plate solar ...

AI Technical Summary

Problems solved by technology

Although the vacuum tube solar collector has the advantages of good antifreeze and frost resistance and small heat loss coefficient, and the flat plate solar collector has the advantages of high thermal efficiency, there are many problems in the existing solar collectors, such as, The vacuum tubes of vacuum tube solar collectors have problems such as water leakage, damage, and difficulty in repairing, while flat-plate solar collectors have problems such as low heat collection efficiency, easy fouling of water pipes, and difficult cleaning.

Moreover, existing solar collectors can only be used to heat water alone for domestic use or to heat air alone for indoor heating

In order to provide domestic hot water while heating the room, it usually requires the use of other auxiliary equipment, which consumes a lot of power, and after the existing solar collectors heat the water, some heat will still not be fully utilized, resulting in energy loss
