Abstract
The utility model relates to a concentrating type plate solar collector comprising a casing, which is a heat insulation case, and a glass cover plate arranged on the casing. A compound parabolic concentrator, above which a plurality of branch pipes are arranged, is arranged inside the casing. Plated with a selective absorbing coating outsides, the branch pipes are connected with the collector, one end of each branch pipe is a medium inlet while the other end is a medium outlet. When the sunshine irradiates the parabolic concentrator and the branch pipes through the cover plate, the concentrator then reflects the sunshine to the branch pipes to heat the heat-conducting medium inside the pipes, and a plurality of heat collecting pipes are connected with a water tank, thus the water temperature rises due to repeat recycle. The utility model has the advantages of applicable to bad water quality areas, hard to scale in winter, and widely using.
Description
Technical field
The utility model relates to a kind of focus type plate-type solar thermal collector, belongs to the technical field of solar water heater.
Background technology
Existing flat type solar heat collector is the composite construction of fin and copper pipe combination, scribbles selective coating at fin surface.The collector area of this structure is big, but thermal-radiating area is also big, has therefore improved the performance of heat collector.
Summary of the invention
The purpose of this utility model is that a kind of focus type plate-type solar thermal collector will be provided, and it adopts compound parabolic concentrator (CPC), sunlight is gathered in long-pending the going up of less hot side reduce heat waste.
The structure of focus type plate-type solar thermal collector is that shell 5 is insulation casings, and compound parabolic concentrator 2 is housed in the shell 5, and its top is an arm 3, and arm 3 surfaces are coated with coating for selective absorption; Heat collector 4 is connected with arm 3, and the one end is working medium import 6, and the other end is a sender property outlet 7, and glass cover-plate 1 is housed above the shell 5.The plated film on arm 3 surfaces is magnetron sputtering inteferometer coatings.
The advantage of focus type plate-type solar thermal collector is to adopt parabolic condenser to make sunlight be similar to parallel radiation and improved the optically focused characteristic, tube-surface scribbles the magnetron sputtering inteferometer coating and can improve absorptivity, pipeline adopts parallel structure, in the pipeline each section water resistance is all identical, thereby has solved the phenomenon of mixed water.The heat-conducting medium (high drain body) that adopts non-water in the arm is less scaling and be applicable to the area that water quality is relatively poor, has enlarged its scope of application.Shell is that the insulation casing is difficult for heat radiation.
Description of drawings
Fig. 1. focus type plate-type solar thermal collector schematic diagram
Fig. 2. and poly-pipeline schematic diagram
By Fig. 1,2, shell (5) is an insulation casing, and compound parabolic concentrator (2) is housed in the shell (5), and its top is arm (3), and arm (3) surface is coated with coating for selective absorption; Heat collector (4) is connected with arm (3), and the one end is working medium import (6), and the other end is sender property outlet (7), and glass cover-plate (1) is housed above the shell (5).
Circulation line has adopted parallel-connection structure as can be known from Fig. 2, and its advantage is that pipeline inside water resistance everywhere is all identical, has so promptly solved the problem of mixed water.
The specific embodiment
The irradiation of sunlight sees through glass cover-plate (1) and arrives parabolic condenser (2) and arm (3), and the sunlight that is radiated at concentrator (2) almost all reflexes to and adds the interior heat-conducting medium of hot leg pipe (3) on the arm (3); Heat-conducting medium circulation in the arm (3) flows in the heat collector (4); This heat collector (4) is connected with outer tank, through circulating repeatedly the water in the water tank is heated.Because shell (5) is the insulation casing, so heat scatters and disappears less.Heat-conducting medium in the arm (3) is the organic substance of non-water, thereby it is less scaling, is particularly useful for the relatively poor area of water quality.Owing to freeze and to move, adopt heat-conducting medium just not have this shortcoming, and the scope of application is increased greatly in the winter time.
Adopt parabolic condenser can make full use of solar energy, at this moment sunlight is similar to parallel rays, usually the subtended angle of the sun has only 0.0093 radian, the plated film that props up tube-surface has improved absorptivity, and emissivity is lower, this film is the magnetron sputtering inteferometer coating, its visible region internal absorption factor 〉=93%, and infrared emittance≤7%.
Claims (2)
1. a focus type plate-type solar thermal collector is characterized in that shell (5) is an insulation casing, and compound parabolic concentrator (2) is housed in the shell (5), and its top is arm (3), and arm (3) surface is coated with coating for selective absorption; Heat collector (4) is connected with arm (3), and the one end is working medium import (6), and the other end is sender property outlet (7), and glass cover-plate (1) is housed above the shell (5).
2. solar thermal collector according to claim 1 is characterized in that the plated film on arm (3) surface is the magnetron sputtering inteferometer coating.
