Abstract

The utility model relates to a flat plate type solar collector, and belongs to the field of solar application. For a known flat plate type solar collector, a slab core is manufactured by precious metals copper and aluminum, thus the cost is too high; only one layer of glass is arranged on the slab core, thus the heat insulation is low; pipe orifices extend from two sides, and the mounting distance on the wall surface is great, thus the appearance is bad. According to the technology, a glass plate with a plurality of through holes (5) is taken as the slab core (1), the slab core is arranged in the middle of a flat box (2), two ends of the flat box are sealed with the surface of the slab core, the sealing space is vacuumized so that the upper, lower, left and right surfaces of the slab core are vacuum heat insulation and preservation layers, and a mouthpiece (4) of a common flow pipe (3) is inserted in through holes at two ends of the slab core (1), so that a flat plate type solar all-glass vacuum collector is formed; the components are all formed through moulds after glass material is heated and melted, thus the cost is extremely low; the vacuum heat insulation heat efficiency is high; the orifices (6) extend out from the back, and are arranged on the wall surface without intervals; a glass curtain wall can be replaced, thus the integration of solar energy and buildings is realized.

Description

A kind of flat type solar heat collector

Technical field

The utility model is a kind of flat type solar heat collector, belongs to the Application of Solar Energy field.

Background technology

Known flat type solar heat collector, adopt copper aluminium sheet core, and cost is too high, flows altogether the mouth of pipe of pipe and draws from both sides, on metope, installs, and the distance between sheet and sheet is large, installs inconvenient, also not attractive in appearance.

Summary of the invention

The purpose of this utility model, be to provide a kind of low cost, a kind of flat type solar heat collector easy for installation on metope.

Its solution is, flat type solar heat collector, to make the plate core with the glass plate with some through holes, the upper surface of plate core has the domestic animal of selection absorber coatings, the plate core is placed in the middle of the flat box of glass, the two ends of flat box and the sealing of plate wicking surface, seal cavity vacuumizes, the sealing aspirating hole, make the plate core up and down four faces be the vacuum heat-insulating layer; Flow altogether pipe and have and the corresponding some ozzles of plate core through hole, insert the ozzle that flows altogether pipe in the through hole at plate core two ends; The mouth of pipe that flows altogether pipe is arranged on the middle part of common stream pipe, stretches out from behind.The parts of heat collector are made of glass entirely.

Heat collector, without copper aluminium, is made low price entirely of glass; The vacuum heat-preserving thermal efficiency is high.

The accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model

The specific embodiment

Below in conjunction with Fig. 1, the specific embodiment of the present utility model is described, Fig. 1 is schematic diagram, is the rearview of seeing from behind.

The parts of flat type solar heat collector are made of glass entirely, by after glass or frit heating and melting, make plate core (1) with mould molding for the glass plate with some through holes (5), and make and select the domestic animal absorber coatings at the upper surface of plate core (1), again plate core (1) is placed in to the centre of the flat box of glass (2), between plate core (1) and the flat box of glass (2), the supporter that bears atmospheric pressure is arranged, supporter is spot-like projections, it is integrated that supporter can be produced on the outer surface homogeneity of plate core (1), the inner surface homogeneity that also can be produced on flat box (2) is integrated, plate core (1) is stuck in the middle of supporter, face seal by the two ends of flat box (2) and plate core (1), sealing can be used the glass powder with low melting point welded seal, seal cavity vacuumizes and seals aspirating hole, make four faces up and down of plate core (1) be the vacuum heat-insulating layer, stream pipe (3) has and plate core (1) the corresponding some ozzles of through hole (4) altogether, inserts the ozzle (4) of stream pipe (3) altogether in the through hole at plate core (1) two ends, and seals the gap of its insert division, the mouth of pipe (6) of stream pipe (3) is arranged on the middle part of common stream pipe (3) altogether.Such heat collector, just become a kind of all-glass vacuum flat plate collector.

This heat collector is made of glass material entirely, without precious metals such as copper aluminium, so, cost is very low, and low price is again vacuum heat-preserving, the light book of figure, the thermal efficiency is high, is convenient to popularization and application, the mouth of pipe (6) of stream pipe (3) is arranged on common stream pipe middle part altogether, from the heat collector back, stretches out, and just sees a just sheet glass from front, this installs on metope, there is no spacing, can embody the effect of glass curtain wall, combine together with building, accomplish building integration.

The improvement of present technique, be to apply reflective space adiabatic heat-insulation coating on the surface of common stream pipe (3), reduces the heat radiation of flowing altogether pipe.

The further improvement of present technique, be the reflective space adiabatic heat-insulation of the backside coating coating at plate core (1), with the infra-red radiation of suppressing plate core, further strengthens heat insulation effect.
