Abstract

The invention relates to a box-type solar device with a Fresnel lens. The box-type solar device is characterized in that the large-size tabulate Fresnel lens is adopted to replace two large-size glass plates of the normal box-type solar device. The box-type solar device with the Fresnel lens is simple in structure and high in thermal efficiency and can be made into a box-type solar water heater or a box-type solar cooker and the like.

Description

Box-type solar device with Fresnel Lenses
Technical scheme
The present invention is a kind of box-type solar device, refers in particular to a kind of box-type solar device with Fresnel Lenses.
Background technology
Chinese patent 91203175 line focus black box formula solar heat exchangers make the sunlight focusing of wire enter the black box from slit, but slit causes solar heat to overflow and lower efficiency, and the parabolic lens cost of its automatic tracks sunlight is high.
Summary of the invention
The present invention is a kind of box-type solar device with Fresnel Lenses.
Its technical scheme is: Fresnel Lenses is fixed on hermetic incubator top, the point-like sunlight that Fresnel Lenses focuses on enters in the incubator from rectangle heat resistant glass window, because rectangle heat resistant glass window size is than large several times of the sunlight focusing of point-like, therefore can be from the servo control mechanism of the motion tracking sun, its advantage be simple in structure, cost is lower, purposes is many.
The specific embodiment
When the present invention makes the box-type solar water heater, make the dewar formula vacuum incubator with mirror face stainless steel, its inner bag scribbles light-Re conversion black chrome coating, under hermetic vacuum incubator, water inlet pipe is housed, depotition cock is equipped with on top, and at the rectangle heat resistant glass window that vacuum incubator top cementation 1-2 pieces of quartz glass, transparent glass-ceramics etc. are done, it is of a size of 100 * 300mm, at a distance of the 200mm eminence, cementation has a slice area 1m on the vacuum incubator top 2About short focal length Fresnel Lenses.
When the present invention makes box-type solar collector, the incubator that hard bubbles with the perfusion polyurethane, its inner bag is coated with the light that useful epoxy resin and carbon black or CNT form-Re conversion coating, in the openable insulation case lid also cementation the heat resistant glass window is arranged, there is the short focal length Fresnel Lenses of a slice the incubator side of covering also cementation.
Certainly, above-mentioned two kinds of box-type solar devices with Fresnel Lenses all are equipped with safety air vavle, also can install the removable plane mirror of 1-2 sheet additional to increase lighting quantity, are installed to receive long the sunlight time towards south.

Claims (2)

1. the box-type solar device with Fresnel Lenses is comprised of Fresnel Lenses and incubator, it is characterized in that: Fresnel Lenses is fixed on hermetic incubator top.
2. use as claimed in claim 1 the box-type solar device of Fresnel Lenses, it is characterized in that: there is rectangle heat resistant glass window on the incubator top.
