Abstract
The invention relates to a novel flat-plate solar collector, which comprises a water inlet, a water outlet and a heat-collecting plate bundle, wherein the heat-collecting plate bundle is formed by overlaying two identical flat plates, and is welded by laser permeation; a circulating channel of which the section is oval or oblate is formed by charging; a circulating channel in the plate bundle is taken as a water channel; a sheet bar on one side facing sunlight is plated with a black chromium coating or other coatings, so that the heat storage capacity and solar radiation absorptivity of the sheet bar are increased. The novel flat-plate solar collector has the advantages of compact structure, easiness in machining, low cost, easiness in assembling and regulating, large water flow, small flowing resistance and high heat-collecting efficiency.
Description
Technical field
The present invention relates to a kind of novel flat-plate solar thermal collector, specifically a kind of heat collectors for solar water heater.
Background technology
Along with modern industry and social development, human society strengthens day by day to the dependence of resource and the energy, and as everyone knows, tellurian resource and the energy are limited, therefore develop new forms of energy, regenerative resource is necessary.Solar energy is utilizable the abundantest as the mankind, is also cheap, the most clean energy, tool development prospect.In the exploitation of solar energy, solar water heater technology be the most ripe, practical application at most and economically can with a kind of renewable energy technologies of conventional energy resource competition.
The core component of solar water heater is exactly solar thermal collector.A lot of researchers have carried out improving design to solar thermal collector.The patent No. is the scheme that 200810123162.9 Chinese patent " permutation and combination of U-shaped pipe and stack design in solar water heater heat collection gate " discloses a kind of permutation and combination about U-shaped pipe in solar water heater heat collection gate and stack design, U-shaped pipe in vacuum tube is first connected and is connected in parallel on two exchanging tubes again, U-shaped pipe forms thermal-collecting tube group by the mode of series connection, extended the time that water is detained in U-shaped pipe, improved the heating rate that obtains of water, water inlet pipe and outlet pipe by several thermal-collecting tube groups is connected in parallel on respectively on cold exchanging tube and heat-exchange tube again, and the sectional area sum of water pipe is arranged to be in close proximity to the sectional area of heat-exchange tube, although improved cold, the convection velocity of hot water, but water flow resistance is large, the problem that the water yield is little is not still resolved.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, a kind of novel flat-plate solar thermal collector is provided, this solar thermal collector has compact conformation, and flow resistance is little, and discharge is large, collecting efficiency is high, the advantages such as bearing capacity is strong, is easy to processing, with low cost, the shortcomings such as solar thermal collector flow resistance was large in the past, and outlet water temperature is little have been overcome.
The technical solution adopted in the present invention is:
A kind of novel flat-plate solar thermal collector, comprise water inlet 1, delivery port 2 and collecting plate bundle 3, collecting plate bundle 3 is to be superimposed by two identical plates, utilizing laser penetration welding, is oval or oblate circulation canal 4 by pressurising Formation cross-section, and collecting plate bundle inner cycle channel 4 is as water circulation channel, electroplating black chromium coating or other coating on the plate towards sunshine one side, increase heat storage capacity and the absorptivity to solar radiation of flat plate; Collecting plate bundle 3 both sides arrange respectively water inlet 1 and delivery port 2.
In the present invention, collecting plate bundle 3 is welded and fixed by sealing wire 5 and plate surrounding sealing wire 6 in the middle part of some corresponding plates by two relative plates, and wherein the sealing wire 5 at plate middle part is parallel with the right and left of plate, and its length is less than the plate left and right length of side.
In the present invention, described water circulation channel is through-type or S type.
In the present invention, the plate of the metal materials such as collecting plate Shu Caiyong stainless steel, copper, aluminium.
In the present invention, at least one water inlet 1 is set on collecting plate bundle 3, at least one delivery port 2.
Advantage of the present invention is:
Flat-plate solar collector reasonable in design of the present invention, this collector structure is compact, flow resistance is little, discharge is large, bearing capacity is strong, collecting efficiency is high, with low cost, is easy to processing.
