Abstract
The utility model relates to a middle-high-temperature solar photo-thermal converter which is characterized in that a cavity body with a closing interlayer is formed by an inner wall and an outer wall. The inner wall is a hemispheric metal shell, a hollow hemispheric cavity body is arranged in the shell, a solar absorbing coating is coated on the surface of the shell, an opening of the hemispheric inner wall is a light incidence opening, the outer wall is a hemispheric or barrel-shaped metal shell, and a liquid inlet and a liquid outlet which are communicated with a closing interlayer space are formed in the outer wall. The middle-high-temperature solar photo-thermal converter is characterized in that a double-layer cavity body structure is adopted, the inner wall of the cavity body is designed into a hemispheric face, and the solar absorbing coating is coated on the inner wall of the cavity body, so that the middle-high-temperature solar photo-thermal converter not only increases a light receiving area, but also increases a contacting area between the converter and liquid in the interlayer, improves solar photothermal conversion efficiency, meets various requirements of working and life, and can be applied to a disc type photo-thermal system of high-power light gathering.
Description
Technical field
The utility model relates to a kind of solar energy optical-thermal conversion equipment, particularly has the middle high temperature solar photothermal converter of high photo-thermal conversion efficiency.
Background technology
At present, the solar energy heat utilization mainly comprises: solar vacuum-tube water heater and tower, slot type, dish formula photo-thermal system.Solar vacuum-tube water heater utilizes vacuum tube to receive solar energy optical-thermal and changes, though be widely used, its photo-thermal conversion efficiency is lower, the heated liquid temperature is lower, can only satisfy general life requirement, the utilization of solar energy is abundant inadequately, and the scope of application has certain limitation.Photo-thermal conversion efficiency higher solar energy such as tower, slot type, dish formula utilize system also to be in the development stage, utilization and extention widely not, and the disc type solar energy system is because its tracking mode flexibly, and the light of high power such as converges at characteristic, receives much concern.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, middle high temperature solar photothermal converter that photo-thermal conversion efficiency is high.
Technical solution of the present utility model is: high temperature solar photothermal converter in a kind of, it is characterized in that constituting the cavity with closed sandwich by inner and outer wall, wherein inwall is the hemispherical metal-back, be the hollow hemispherical cavity in the shell, shell surface-coated solar energy absorbing coating, the opening of hemispherical inwall is the light entrance port, and outer wall is hemispherical or barrel-shaped metal-back, and outer wall is provided with inlet and the liquid outlet that is communicated with enclosed air space.The light entrance port is provided with the clear glass that seals, and which is provided with vacuum pumping opening, is convenient to the hollow hemispherical cavity is vacuumized, and makes to become vacuum state in the hollow hemispherical cavity.
The middle high temperature solar photothermal converter that the utility model provides, adopt double-layer cavity structure, the opening of hemispherical inwall is the light entrance port, the sunray that converges through high power through the light entrance port to cavity inner wall, cavity inner wall is designed to semispherical surface and applies solar energy absorbing coating, both increased light receiving area, also increased with interlayer in the contact area of liquid, light overflows minimizing in the reflection of cavity simultaneously, heat energy can be conducted efficiently to liquid, improve photo-thermal conversion efficiency greatly.More the light entrance port can be sealed with transparency glass plate, and will vacuumize in the cavity, stop hot-air and run off, reduce heat loss.
Characteristics of the present utility model are: adopt double-layer cavity structure, and cavity inner wall is designed to hemisphere face and applies solar energy absorbing coating, both increased light receiving area, also increase the contact area with the interior liquid of interlayer, improved the solar energy thermal conversion efficiency, liquid by circulation transports out the heat energy of the sun rapidly, satisfies various needs in work and the life.This photothermal converter can be applicable in the dish formula photo-thermal system that high power light converges.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of another embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the housing of middle high temperature solar photothermal converter is the hollow hemispherical cavity of the band closed sandwich that is made of hemispherical inwall 2 and hemispherical outer wall 1.The opening of hemispherical inwall is the light entrance port, and the light 7 that converges that the solar energy collecting system provides enters in the chamber through this mouthful.The horizontal epitaxy part of light entrance port preferably is provided with the transparency glass plate 4 that seals for connecting the circular dull and stereotyped 3 of inwall and outer wall on the light entrance port, can be provided with vacuum pumping opening on it.Air in the hollow hemispherical cavity is extracted out, to reduce the heat loss that cross-ventilation brings.Outer wall is provided with inlet 6 and liquid outlet 5, is communicated with the circulatory system.Wrap up adiabator layer on the outer wall.Apply light-absorbing coating on the inner surface of inwall, improve the photo-thermal conversion yield of inwall.
Fig. 2 provides the structural representation of another embodiment, and the outer wall 1 of middle high temperature solar photothermal converter is drum shape, also can be other shapes, and other structures are identical with embodiment 1, repeat no more.
Claims (2)
