Abstract
The utility model belongs to the technology of saucer-type Stirling engine solar power generation, and relates to the improvement to an end opening of a heater collector of a saucer-type Stirling engine. The end opening structure comprises an annular flange (1a) arranged at the position of the end opening of the heat collector (1), and is characterized in that a circular glass heat protection cover (2) is arranged outside the end opening of the heat collector (1). According to the end opening structure, a novel structure of the end opening of the heat collector of the saucer-type Stirling engine is provided, heat losses of the end opening of the heat collector of the saucer-type Stirling engine are reduced, and the heat efficiency of the saucer-type Stirling engine is improved.
Description
Technical field
The utility model belongs to dish formula Stirling solar generation technology, relates to the improvement to dish formula Stirling engine heat collector port.
Background technology
Dish formula Stirling engine is a kind of piston-mode motor that utilizes solar energy to be generated electricity, heat collector cavity be in this engine for absorbing the assembly of solar energy, this assembly has determined the generated output of engine to the number of solar absorption.Heat collector cavity equals the poor of the next solar energy of reflection and this place's leaking heat to the uptake of solar energy.How much the solar energy that reflection comes determined jointly by light intensity at that time and the size of speculum area, and the leakage heat of heat collector cavity is relevant with many factors.The structure that the port organization of current a kind of dish formula Stirling engine heat collector is gone out after glass heat protective cover, ceramic chamber lining and bolt assembly referring to Fig. 1, its heat collector cavity is open type.Its shortcoming is: because the port of open type has caused the loss of heat, reduced the thermal efficiency of dish formula Stirling engine.
Summary of the invention
The purpose of this utility model is: propose a kind of new construction of dish formula Stirling engine heat collector port, to reduce thermal loss, to improve the thermal efficiency of dish formula Stirling engine.
The technical solution of the utility model is: dish formula Stirling engine heat collector port organization, the annular flange 1a that comprises heat collector 1 port, it is characterized in that: a hot protective cover 2 of circular glass is arranged, the diameter of hot protective cover 2 is greater than the internal diameter of heat collector 1 port and is less than the external diameter of annular flange 1a, near the circumference place, 3～6 the hot protective cover bolts hole that are uniformly distributed along the circumference are arranged at hot protective cover 2, the annular flange bolt hole that quantity is identical and position is corresponding that quantity and hot protective cover bolt hole are arranged on annular flange 1a, at each annular flange bolt hole place, a ceramic chamber lining 3 is arranged between annular flange 1a and hot protective cover 2, by bolt assembly 4, hot protective cover 2 and ceramic chamber lining 3 are fixed on annular flange 1a.
The utility model has the advantages that: proposed a kind of new construction of dish formula Stirling engine heat collector port, reduced the thermal loss of engine heat collector port, improved the thermal efficiency of dish formula Stirling engine.Evidence, after adopting structure of the present utility model, the thermal efficiency of dish formula Stirling engine is more than 20%.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, dish formula Stirling engine heat collector port organization, the annular flange 1a that comprises heat collector 1 port, it is characterized in that: a hot protective cover 2 of circular glass is arranged, the diameter of hot protective cover 2 is greater than the internal diameter of heat collector 1 port and is less than the external diameter of annular flange 1a, near the circumference place, 3～6 the hot protective cover bolts hole that are uniformly distributed along the circumference are arranged at hot protective cover 2, the annular flange bolt hole that quantity is identical and position is corresponding that quantity and hot protective cover bolt hole are arranged on annular flange 1a, at each annular flange bolt hole place, a ceramic chamber lining 3 is arranged between annular flange 1a and hot protective cover 2, by bolt assembly 4, hot protective cover 2 and ceramic chamber lining 3 are fixed on annular flange 1a.
Said hot protective cover 2 is used high-boron-silicon glass 3.3 to manufacture, and the thickness of hot protective cover 2 is 3mm～5mm.
Operation principle of the present utility model is: the wavelength of solar radiation heat energy mainly concentrates between 0.3 μ m～3 mum wavelengths, and the main energy of industrial familiar object radiation is greater than the scope of 3 μ m at wavelength, and actual object is selective to the penetration ratio of various radiation, so select, a kind of can be less than the penetration ratio of ripple of 3 μ m to wavelength very large and heat collector cavity self is sent to the very little material of radiant energy penetration ratio that wavelength is greater than 3 μ m---glass is as the hot protective cover of heat collector cavity, both can allow sunshine effectively see through, can also reduce the radiation in the external section of thermal-arrest cavity space, increased a face for heat collector cavity simultaneously, can effectively to entering heat collector cavity, unabsorbed solar energy be reflected, the double absorption of promotion to solar energy, and this hot protective cover has also suppressed the free convection of air in heat collector cavity greatly, further reduced again heat loss.
An embodiment of the present utility model, the internal diameter of heat collector 1 port is 1200mm, and hot protective cover 2 is used high-boron-silicon glass 3.3 to manufacture, and the thickness of hot protective cover 2 is 4mm, and the diameter of hot protective cover 2 is 1500mm.
Claims (2)
