Abstract
The invention discloses a circular pipe type heat collector for a solar water heater. The circular pipe type heat collector is characterized in that a selective absorption coating is directly plated on the outer surface of each heat-absorbing pipe. In the heat collector, the heat-absorbing pipes with the circular sections are closely arranged side by side, and the selective absorbing coatings are plated on the outer surfaces of the heat-absorbing pipes and used as heat-absorbing bodies, thereby simplifying the process of transferring heat to water and avoiding contact thermal resistance. Simultaneously, helical ribbons are built in the heat-absorbing pipes, thereby having the effect of enhancing heat transfer.
Description
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to and a kind of coating for selective absorption is plated in solar water heater heat absorption heat pipe surface, replace the heat absorption hot plate part of classic flat-plate type water heater, and the circular pipe type heat collectors for solar water heater that forms.
Two, background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and dull and stereotyped water heater has appearred comprising in solar water heater, and the plate type solar water heater is opened up markets rapidly with its longer service life and easy installation method.But, still can not adapt to the northern cold cold weather because bigger, hot water programming rate of heat loss and amplitude are poorer slightly than vacuum tube water heater.
At present existing a plurality of patents about the plate type solar water heater, but the patent that coating for selective absorption directly is plated on the circular thermal-collecting tube is not found as yet.Below list several existing relevant patents:
(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates constitute to patent " efficient freeze proof plate type solar water heater ", is full of water in the gap between two metallic plates, and the absorber upper surface is coated with coating for selective absorption.Because the water yield in the absorber gap is fewer, when water freezing expanded, Volume Changes was within the regime of elastic deformation of metallic plate, and can guarantee can be not freezing.
Patent " the built-in many piecemeals assembled flat of circulation pipe type solar water heater " (application number: 200920253847.5) propose a kind of modular plate type solar water heater, this device is designed to the unit that module is with the heat collection body of water heater, is convenient to install and transportation.
Patent " a kind of wall hanging whole pressure-bearing flat plate solar water heater " (application number: 201020192486.0) propose a kind of solar water heater that thermal-arrest layer and storage tank are integrated, the loss of minimizing heat transmission course.
Three, summary of the invention
The present invention proposes a kind of circular pipe type heat collectors for solar water heater that coating for selective absorption directly is plated in the thermal-collecting tube surface.The circular pipe type heat collectors for solar water heater is made of inlet channel, outlet conduit, endothermic tube, lagging casing and transparent insulation cover plate.Inlet channel, outlet conduit and endothermic tube weld together, and the endothermic tube cross section is circular, must closely not interspace side by side, and the endothermic tube outer surface is coated with coating for selective absorption, and helical ribbon is equipped with to strengthen heat exchange in inside.Water directly absorbs heat on tube wall after entering endothermic tube by inlet channel, has simplified endothermic process, has improved the heat transmission speed.
Four, description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the overall schematic of this device.
Fig. 2 is the absorber schematic diagram figure of this device.
Fig. 3 is this device absorber side view figure.
Fig. 4 is this device endothermic tube cutaway view.
The position of marking is respectively among the figure: 1, insulation shell; 2, transparent insulation cover plate; 3, inlet channel; 4, endothermic tube; 5, outlet conduit; 6, helical ribbon.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The external attemperater of the inlet channel of circular pipe type heat collectors for solar water heater and outlet conduit, water in water tank enters in the endothermic tube of heat collector by inlet channel.The endothermic tube outer surface is coated with coating for selective absorption, and solar energy is converted to heat energy endothermic tube is heated up, and the water of water back inside.Ducted water is through circulating, and is stored in the attemperater after being heated to uniform temperature.
