Description
Technical field
The utility model relates to a kind of vacuum flat-plate solar thermal collector.Belong to the solar energy utilization technique field.
Technical background
Solar thermal collector in the market mainly is flat and vacuum tube class heat collector.Flat type solar heat collector is because the cavity poor air-tightness that cover plate and shell form and antivacuum, and elevated temperature heat efficient is low, winter while easy frozen pipe; Vacuum tube class heat collector exist can not pressure-bearing and also actual effectively collector area cause the thermal efficiency to hang down problem for a short time.This two classes solar thermal collector all can not provide high-temperature-hot-water simultaneously, so the high-temperature-hot-water solar thermal utilization is blank substantially.
The utility model content
The purpose of this utility model provides a kind of 1. in conjunction with the advantage of flat type solar heat collector and vacuum tube class heat collector, the collecting efficiency height of getting rid of their shortcoming separately, be not afraid of and freeze, 2. the vacuum flat-plate solar thermal collector of the new high efficiency of high-temperature-hot-water can be provided.
For achieving the above object, the technical solution of the utility model is: a kind of vacuum flat-plate solar thermal collector, this heat collector be by circular arc camber transparent glass cover plate (1), sealing layer (2), and shell (3), thermal-arrest plate (4), vacuum valve (6) constitutes; Thermal-arrest plate (4) is in the cavity that is made of circular arc camber transparent glass cover plate (1) and shell (3), and the heat medium pipe of thermal-arrest plate (4) stretches out in cavity; Vacuum valve (6) is welded on the aperture on the shell (3); Circular arc camber transparent glass cover plate (1) and shell (3) are by sealing layer (2) air-tightness sealing-in; The heat medium pipe of thermal-arrest plate (4) and the combination of shell (3) binding site air-tightness; By circular arc camber transparent glass cover plate (1), sealing layer (2), shell (3), the heat medium pipe (5) and the vacuum valve (6) of thermal-arrest plate (4) just constitute airtight cavity; Inner surface at shell (3) covers the antiradiation coating; Outer surface at shell (3) is laid heat-insulation layer; In order to overcome the strength of glass problem, the unsettled light transmission part of circular arc camber transparent glass cover plate (1) is designed to circular arc cylindrical or gradual change spherical.
After implementing such scheme and since be vacuum be again dull and stereotyped heat collector, so collecting efficiency height in common civilian low temperature range not only is not afraid of and is frozen, collecting efficiency height in high temperature industry and commerce range of application can hold high pressure simultaneously, and high-temperature-hot-water can be provided.

The specific embodiment
The utility model is by circular arc camber transparent glass cover plate (1) shown in Fig. 1,2,3,4, sealing layer (2), and shell (3), thermal-arrest plate (4), vacuum valve (6) constitutes.
Thermal-arrest plate (4) is in the cavity that is made of circular arc camber transparent glass cover plate (1) and shell (3), and the heat medium pipe of thermal-arrest plate (4) stretches out in cavity.Vacuum valve (6) is welded on the aperture on the shell (3); Circular arc camber transparent glass cover plate (1) and shell (3) are by sealing layer (2) air-tightness sealing-in; The heat medium pipe of thermal-arrest plate (4) and the combination of shell (3) binding site air-tightness, circular arc camber transparent glass cover plate (1) like this, sealing layer (2), shell (3), the heat medium pipe (5) and the vacuum valve (6) of thermal-arrest plate (4) just constitute airtight cavity; By vacuum valve (6) cavity is vacuumized.
Inner surface at shell (3) covers the antiradiation coating.Outer surface at shell (3) is laid heat-insulation layer.
Thermal-arrest plate (4) is the high heat carrier of thermal conductivity, the surface coverage coating for selective absorption.
The unsettled light transmission part of circular arc camber transparent glass cover plate is circular arc cylindrical or gradual change spherical.
The circular arc camber transparent glass cover plate of circular arc cylindrical as shown in Figure 3.
Gradual change spherical circular arc camber transparent glass cover plate as shown in Figure 4.The outer surface of gradual change sphere is the arc top with summit O, circular arc summit O remains unchanged, the limit that two end points of circular arc prolong rectangle ACA ' C ' is the orbiting motion of eye A-B-C-D-A ' and A '-B '-C '-D '-A respectively at the same rate, thereby it is constant to form the arc top, gradual change sphere from circular arc AOA '-BOB '-COC '-DOD '-A ' OA, inner surface is the arc top with the some O ' under the O of summit, the limit motion that the two-end-point one same mode of circular arc is prolonged rectangle A " C " A " ' C " ' forms another gradual change sphere. and housing is the part of this circular arc camber transparent glass cover plate on the figure, and the bottom surface is a sealing surface.
