Abstract

The invention relates to a pantile solar concentration heat collector which belongs to the field of solar energy application. The pantile solar concentration heat collector comprises a glass pantile line focusing light concentrator, a heat collector and an outer frame; the glass light concentrator adopts the focusing method of a linear Fresnel lens to adjust the matching of the width of a focusing light band and that of the heat absorption part of the heat collector, so that the incident sunlight is focused on the fixed solar heat collector, the solar radiation energy density of the heat collector in unit area is improved, the temperature of a heat absorbing medium of the heat collector is improved, and the wide application of the high-temperature heat collector in the field of solar energy.

Description

Technical field

[0001] The invention relates to the field of solar photothermal, in particular to a corrugated tile solar collector. Background technique

[0002] At present, most of the solar water heaters are vacuum tube type or flat plate type. There are two heat collection methods: water circulation and medium heat exchange. Higher and easier to combine with buildings, it is widely used abroad, but it is difficult to obtain medium and high temperature applications. At present, solar thermal applications are becoming more and more widely used, such as solar air conditioners, solar dryers, solar Stirling thermal power generation, solar steam ovens, etc. The development trend towards medium and high temperature is obvious, which requires solar concentrated heat collection suitable for medium and high temperature applications It just so happens that we have solved the problem of mass production of glass linear Fresnel condenser lenses, and realized the use of ultra-clear gl...

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the corrugated tile solar concentrator includes 1 glass corrugated tile line focusing concentrator, 2 heat collectors, and 3 outer frames.

[0020] In the present invention, the concentrator adopts a line-focusing Fresnel lens produced by ultra-clear glass, and the lens focusing type is linear, which can obtain several times the required multiples of the focused light band, and the focal band width is as high as 2-2 The width of the heat-absorbing metal plate is corresponding, and the metal plate is welded with 2-3 high-efficiency heat-conducting, heat-absorbing and pressure-bearing metal tubes. The inlet end of the metal tube is 2-33 medium into the metal tube, and the middle return coil is 2-31 evaporator. The outlet end of the evaporator is a 2-35 steam outlet metal pipe, and the end of the steam outlet pipe enters the 2-...
