Abstract
The invention provides a high-reflection solar cooker, which mainly comprises a cooker body, a support and a tracking system; a refection enhancing film is coated on the reflecting surface of the cooker body; the refection enhancing film has a multilayer structure and can reflect sunlight in a wideband range; and most of sunlight reflected by the surface of the cooker body is reflected to the focus position of the cooker body by positioning of the tracking system. The refection enhancing film is combined with the solar cooker, so that most of the incident light of the sun can be reflected to the focus position, light loss is reduced, the area of the cooker body is reduced, the utilization rate of the light is improved, and the solar cooker is convenient and practical.
Description
Technical field
The present invention relates to a kind of reflective kitchen range, especially a kind of high reflected solar energy kitchen range.
Background technology
Solar energy stove is that larger area sunlight is focused on the bottom of a pan, makes temperature be raised to higher degree, to satisfy the cooking requirement.The critical component of this solar cooker is a condenser, and the selection of specular material is not only arranged, and also has the design of geometry.Prevailing reflective mirror is silver-plated or the aluminum plating glass mirror, and aluminium polishing minute surface and the mylar material etc. of aluminizing is also arranged.The minute surface of solar energy stove designs, and mostly adopts the optically focused principle of the paraboloid of revolution.On mathematics if parabola around one week of main axis rotation, the face of gained promptly is called " paraboloid of revolution ".If a branch of directional light is arranged along this parabola of main shaft directive, run into paraboloidal reflectively, then light all can be concentrated the position that reflexes to fixed point, then form optically focused, or make " focusing " to act on.Use as solar cooker, require to form a focal plane, just can reach the purpose of heating in the bottom of a pan.In other words, it is not strictly with on solar ray collecting to one point, but requires certain focal plane.Confirmed after the focal plane that we just are not difficult to study the optically focused ratio of concentrator, it is the power of decision light concentration type solar cooker and the key factor of efficient.Optically focused can be tried to achieve with formula than K: K=daylighting area/focal plane area.Daylighting area is meant solar cooker effective projected area of mirror surface sunlight in use.According to the experience of China's popularization solar cooker, the light concentration type solar cooker of 700～1200 watts of power of design, daylighting area is about 1.5～2.0 square metres usually.Indivedual large-scale steam solar cookers also are light concentration type solar cookers, but its daylighting area is bigger, and what have will be more than 5 square metres.
At present, the reflecting surface of solar energy stove generally adopts the plating face, and its reflectivity is mainly by its metallic reflector decision; But under such situation; The reflection of light loss also is bigger, usually need increase reflective surface area and solve this problem, has reduced light utilization efficiency.
Summary of the invention
To the problems referred to above, the present invention provides a kind of high reflected solar energy kitchen range.
A kind of high reflected solar energy kitchen range; Mainly form by stove, support and tracking system; It is characterized in that scribbling at the stove reflecting surface and increase anti-film, increasing anti-film is sandwich construction, can in wider frequency range, reflect sunshine; Through the location of tracking system, make the focal position that reflexes to stove through the sunshine overwhelming majority of stove surface reflection.
Remarkable result of the present invention is with increasing combining with solar energy stove of anti-film, make the sun incident light overwhelming majority to reflex to the focal position, reduce light loss, so both can reduce the area of stove, having improved light utilization efficiency again, and is convenient and practical.
Description of drawings

Wherein: 1, increase anti-film; 2, stove; 3, tracking system.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified: scribble at stove 2 reflectings surface and increase anti-film 1; Increasing anti-film is sandwich construction; Be the stack of the laminated coating that increases anti-film 1 in a plurality of spectral regions, and spectral region all interconnects, can in wider frequency range, reflect sunshine; Through the location of tracking system 3, make the focal position that reflexes to stove through the sunshine overwhelming majority of stove surface reflection.
Apply the present invention in solar energy stove and other derived products, make the sun incident light overwhelming majority to reflex to the focal position, reduce light loss; So both can reduce the area of stove; Improved light utilization efficiency again, convenient and practical, can light reflectivity be increased to more than 95%.
Claims (3)
1. one kind high reflected solar energy kitchen range; Mainly form by stove, support and tracking system; It is characterized in that scribbling at the stove reflecting surface and increase anti-film, increasing anti-film is sandwich construction, can in wider frequency range, reflect sunshine; Through the location of tracking system, make the focal position that reflexes to stove through the sunshine overwhelming majority of stove surface reflection.
2. high reflected solar energy kitchen range as claimed in claim 1 is characterized in that scribbling at the stove reflecting surface and increases anti-film.
3. high reflected solar energy kitchen range as claimed in claim 1, it is characterized in that increasing anti-film is sandwich construction, can in wider frequency range, reflect sunshine.
