Description
Technical field
The utility model relates to technical field of solar utilization technique, is specifically related to a kind of heat collector.
Background technology
Along with spreading gradually of global energy crisis, utilize solar energy as the energy constantly development in exploratory development, because solar energy is inexhaustible, nexhaustible, and solar energy is pollution-free, is perfect energy sources.The solar water heater of popularizing very much in life that utilizes solar energy is that solar energy is converted into heat energy, and water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.Usually solar water heater is made up of heat collector, storage tank, support and related accessories, solar energy is converted to heat energy mainly rely on heat collector.The domestic solar water heater's who generally uses principle is as follows on the market: heat collector is subjected to solar radiation surface temperature height, heat collector opaco temperature is low, water just produces temperature difference reaction in the pipe, and the principle of utilizing hot water come-up cold water to sink makes the water generates microcirculation and reaches required hot water.
What the heat collector that uses in the solar water heater generally used is all-glass vacuum thermal-collecting tube.Adopt the all-glass vacuum thermal-collecting tube cost low, but also have following shortcoming: water on must low temperature when adopting on the solar water heater of all-glass vacuum thermal-collecting tube water, can booster during water on the high temperature, be afraid of hail, thermal starting is slow, the maintenance cost height.The solar water heater that uses flat plate collector is also arranged, but the pipeline that the interior pipe of this class flat plate collector adopts metal tube to be welded into usually, reason causes pad the slit to occur owing to expanding with heat and contract with cold etc., the easy seepage of medium in the pipeline, search the breakthrough trouble, for maintenance brings difficulty, influence the service life of heat collector.
The utility model content
The purpose of this utility model is, a kind of flat-plate solar collector is provided, and solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
Flat-plate solar collector, comprise a heat-collecting plate core, it is characterized in that, described heat-collecting plate core comprises that by two aluminium sheet pressings be the heat-collecting plate core matrix that one constitutes, described heat-collecting plate core matrix is provided with an inlet and a liquid outlet, be provided with the thermal-arrest pipeline that is formed by heat-collecting plate core matrix inner hump between described inlet and the described liquid outlet, described inlet and described liquid outlet are by described thermal-arrest pipeline UNICOM.
Adopt two thermal-arrest pipelines that the aluminium sheet pressing is formed as one, problems such as traditional glass heat-collecting vacuum tube booster, maintenance cost height have been avoided, because of it is a disposal molding, good integrity, have that no pad, corrosion resistance are good, structure is relatively thinner, advantages such as usage space is little, heat transfer rate piece, maintenance is few between the operating period.Be provided with inlet liquid is delivered to the thermal-arrest pipeline of heat-collecting plate core from external equipment, liquid outlet will carry the liquid of heat and deliver to external equipment from the thermal-arrest pipeline, form a closed circuit.Above-mentioned design can make the utility model and external equipment partial installation.
Described flat-plate solar collector comprises that also a glass cover-plate, that is arranged on described heat-collecting plate core top is arranged on the backboard of described heat-collecting plate core below, and described glass cover-plate, heat-collecting plate core, backboard are fixed into one by a frame.
Described heat-collecting plate core matrix surface is coated with heat-sink shell, and described heat-sink shell is the black nickel coating that is coated with black nickel.Black nickel coating is black, and solar energy is had higher absorptivity, is coated with black nickel coating at the heat-collecting plate core matrix surface, makes heat-collecting plate core heat absorption efficiency height.
Described glass cover-plate can adopt safety glass, and safety glass is when guaranteeing transmittancy, and the intensity of the safety glass of condition of equivalent thickness is 3～5 times of simple glass, also has good heat endurance, can bear 200 ℃ of difference variation.The utility model is arranged on when outdoor, uses the heat-collecting plate core of safety glass cover plate protection below to avoid boisterous influences such as hail, sleet.
Described heat-collecting plate core below and heat-insulation layer can be set on every side, described heat-insulation layer can be the heat-insulation layer that phenolic aldehyde foam thermal insulation material is made.Phenolic foam material has remarkable advantages such as outstanding thermal and insulating performance, higher operating temperature, outstanding weatherability, environmental protection, thereby effectively avoids heat to run off by backboard from the heat-collecting plate core below.
Beneficial effect: owing to adopt technique scheme, the utlity model has that heat transfer rate is fast, maintenance rate is few, not booster, can bear advantages such as bad weather, high insulating effect.
Description of drawings
Fig. 1 is the structural representation of the utility model heat-collecting plate core.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, flat-plate solar collector comprises a heat-collecting plate core, and it is that one constitutes heat-collecting plate core matrix 1 that heat-collecting plate core comprises by two aluminium sheet pressings, and preferred 0.6mm is thick for the thickness of aluminium sheet.Heat-collecting plate core matrix 1 is provided with an inlet 31 and a liquid outlet 32, is provided with the thermal-arrest pipeline 2 that is formed by heat-collecting plate core matrix 1 inner hump between inlet 31 and the liquid outlet 32, and inlet 31 and liquid outlet 32 are by thermal-arrest pipeline 2 UNICOMs.Heat-collecting plate core matrix 1 surface-coated has heat-sink shell, and heat-sink shell is the black nickel coating that is coated with black nickel.Two blocks of aluminium sheets can adopt disposable extruding inflation technology to form thermal-arrest pipeline 2, when making heat-collecting plate core matrix 1, at first two blocks of aluminium sheets are pushed with air compressor machine, heat-collecting plate core 1 blowpipe after using the blowing pipe to extruding then, blow out thermal-arrest pipeline 2, on the heat-collecting plate core matrix 1 of that face of glass cover-plate, applying black nickel coating at last.Adopt the heat-collecting plate core of said method moulding can avoid problems such as traditional glass heat-collecting vacuum tube booster, maintenance cost height, because of it is a disposal molding, good integrity has advantages such as no pad, corrosion resistance are good, structure is relatively thinner, heat transfer rate piece, and maintenance is few between the operating period.
