Abstract
The utility model discloses a square-pipe-type solar heat collector. The square-pipe-type solar heat collector is characterized in that a heat-absorbing coating is directly plated on the surface of a heat-absorbing pipe, so that the heat absorption of water flow is faster and the heat loss is lower. A heat-absorbing part of the heat collector consists of a plurality of heat-absorbing pipes; the section of each heat-absorbing pipe is rectangular; and one sunward side of each pipe is plated with each heat-absorbing coating. When the square-pipe-type solar heat collector works, cold water enters the heat collector from a water inlet pipe, and flows into all the heat-absorbing pipes in a flow-distributing manner. The heat-absorbing coatings on the surfaces of the heat-absorbing pipes absorb the sunlight to increase the temperature and heat the water in the pipes, and hot water converges into a water outlet pipe, and is conveyed into a water storage tank finally.
Description
One, technical field
The utility model relates to solar energy heat utilization field, refers in particular to a kind of square tube type solar thermal collector.
Two, background technology
Solar water heater is a kind of helioplant that utilizes solar energy to add hot water or heat transfer medium as the energy.The most representative in the prior solar water heater product with vacuum tube type solar energy water heater and plate solar water heater.The vacuum tube collector heat sink is a vacuum tube, and heat loss is little.Compare advantage such as that the plate type solar water heater has is simple in structure, the sunlight footprint is big, seal request is low, it is antifreeze not need, working medium is cheap, response is fast with the vacuum tube type solar energy water heater.But also there are shortcomings such as heat loss is big, collecting efficiency is low.How further to improve the collecting efficiency of solar water heater, be the target that the scientific research personnel pursues always.
The plate type solar water heater mainly is made up of transparent cover plate, absorber plate, water pipe, insulation shell four parts.During work, the absorber plate that scribbles coating for selective absorption is converted into heat energy with solar radiation, and heat is passed to the water that flows in the water pipe through heat conduction.Mostly the compound mode of leaking water between pipe and the absorber plate is welding, and thermal resistance between the two and overall geometry have very big influence to collector efficiency.
The problems referred to above to the plate type solar water heater; Existing some kinds of corrective measures: patent " vacuum flat-plate solar water heater " (number of patent application 200620023546.X) for example; It is characterized in that water storage tank is directly as heat-exchanging water tank; The water storage tank loam cake through the plate glass vacuum heat-collecting, reduces heat loss through reducing pipeline and vacuum heat-insulation as heat exchanger plates.And for example patent " a kind of flat plate solar water heater " (number of patent application 00263980.7) is designed to the cover plate that double glazing presss from both sides vacuum layer with transparent cover plate, reduces heat loss.
Above-mentioned patent working all has certain effect to the thermal efficiency that improves solar thermal collector, but owing to need to use double-layer cover plate, the transmittance that has reduced daylight has increased heat collector weight, is unfavorable for combining with building.
Three, summary of the invention
The purpose that the utility model proposes is to improve the deficiency of prior art, provides a kind of pipe of leaking water to harden with thermal-arrest and closes fully heat transfer efficiency height, solar water heater easy for installation.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Square tube type solar thermal collector is made up of water inlet pipe, endothermic tube, insulation shell, outlet pipe, transparent cover plate, heat absorbing coating etc., it is characterized in that: cold water divides the inflow endothermic tube by water inlet pipe; Some endothermic tubes cross section of heat collector is a rectangle, and one side is coated with heat absorbing coating on the sunny side, and heat absorbing coating absorbs the daylight intensification during work, the water in the heating endothermic tube.Hot water confluxes into outlet pipe.
The utility model makes traditional solar water heater obtain two improvement: the one, and the absorber plate and the pipe of leaking water are combined as a whole, heat transfer efficiency is improved; The 2nd, eliminated because the water pipe that the welding position temperature distortion causes snaps problem.
Four, description of drawings
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the structural representation of this heat collector.
Fig. 2 is the A-A face cutaway view of this heat collector.
Fig. 3 is the B-B face cutaway view of this heat collector.
The position of marking is respectively among the figure: 1, water inlet pipe; 2, endothermic tube; 3, insulation shell; 4, outlet pipe; 5, transparent cover plate; 6, heat absorbing coating.
Five, the specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is explained.
The heat absorbing part of heat collector is made up of some endothermic tubes 2.Endothermic tube 2 cross sections are rectangular, and the side that pipe faces south is coated with heat absorbing coating 6.During work, cold water gets into heat collector from water inlet pipe 1, divides to flow into each endothermic tube 2.The heat absorbing coating 6 on endothermic tube 2 surfaces absorbs daylight and heats up the water in the heating tube.Hot water confluxes and gets into outlet pipe 4, sends into water tank at last.
