And existing photothermal conversion device is complicated, manufacturing cost is high.
Utility model content
In order to solve the problems, such as that photothermal conversion device transfer efficiency is low in the prior art, complicated and manufacturing cost is high,
The utility model provides incorporated light thermoconverter.
Incorporated light thermoconverter provided by the utility model, including outer hemisphere shell and interior hemispherical Shell, the outer hemisphere shell
With interior hemispherical Shell towards it is identical and be tightly connected out section be in crescent shape photothermal conversion chamber.The middle part of the outer hemisphere shell is arranged
There is light inlet, glass is installed at light inlet.The inner wall of the outer hemisphere shell is coated with reflective layer, the outer wall of the interior hemispherical Shell
Coated with light-absorption layer, the inner wall of interior hemispherical Shell is fitted on heat exchanging chamber.
Preferably, the light-absorption layer is nickel black layer.The nickel black layer can effectively absorb energy in sunlight, and luminous energy is turned
It is changed to thermal energy.
Further preferably, the reflective layer is silver coating.The silver coating can reflect light back into light-absorption layer.
Preferably, liquid metal is filled in the heat exchanging chamber, heat pipe stretches into heat exchanging chamber.Liquid is filled in heat exchanging chamber
Metal can quickly and effectively conduct heat.
Preferably, the photothermal conversion intracavitary is filled with transparent liquid heat transferring medium.The transparent liquid heat exchange is situated between
Matter can be water or other liquids, and liquid heat transferring medium can ensure that photothermal conversion chamber is heated evenly everywhere, is prevented as possible
The excessive thermal stress deformation of interior hemispherical Shell.
The utility model compared with prior art, has the advantages that：
Above-mentioned incorporated light thermoconverter, the sunlight after lens are concentrated enter photothermal conversion chamber from light inlet, and sunlight shines
It penetrates on the light-absorption layer of interior hemispherical Shell, part sunlight is thermal energy by sorption enhanced, and other sunlight are reflected onto the anti-of outer hemisphere shell
Photosphere is irradiated to light-absorption layer and carries out photothermal conversion again after reflection；Interior hemispherical Shell is fitted on heat exchanging chamber, can be directly by thermal energy
It conducts to heat exchanging chamber.Photo-thermal is converted by above-mentioned incorporated light thermoconverter, sunlight can constantly be converted in photothermal conversion intracavitary, be changed
The thermal efficiency is high.In the original incident of sunlight, sunlight energy density is high, and photothermal conversion intracavitary initial reflection space is big, reflection time
Number is relatively fewer；After multiple reflections to light-absorption layer periphery, energy is absorbed by light-absorption layer, and the light ray energy after reflection is successively decreased, but
Since light order of reflection increases, it is possible to ensure that light-absorption layer center and periphery are heated evenly as possible, to prevent excessive heat
Stress deformation.Interior hemispherical Shell is fitted on heat exchanging chamber, reduces the number of heat exchange, to reduce heat transfer process heat loss, is carried
High heat transfer efficiency；On the other hand the problem that split type assembling precision prescribed is high, and prestressing force is difficult to control is avoided.
Description of the drawings
Fig. 1 is the sectional view of incorporated light thermoconverter.
1 liquid metal chamber；2 photothermal conversion chambers；21 outer hemisphere shells；211 light inlets；Hemispherical Shell in 22；3 valves；4 steam go out
