Abstract
The invention relates to a flat-panel solar collector comprising a water inlet, a water outlet and a collector plate bundle. The collector plate bundle is formed by stacking two same flat plates and laser penetration welding; an elliptic or oblong section circulation passage is made by pressurizing the collector plate bundle; the circulation passage in the collector plate bundle serves as a water passage. The water passage is in a novel structure, so that flowing distance of water in the plate bundle is prolonged and water can be subjected to full heat exchanging in the plate bundle; meanwhile, turbidity of the water in water passage is improved, and heat exchange is enhanced. A plate on one side facing to sunlight is provided with a plated black chromium coating or other coatings, so that heat storage capacity of the plate is improved and absorption rate of solar radiation is increased. The flat-panel solar collector is compact in structure, simple to manufacture, low in cost, easy to assemble and adjust, high in water flow, low in flowing resistance and high in heat exchanging efficiency; the water can flow in the water passage for a longer period of time.
Description
Technical field
The present invention relates to a kind of flat-plate solar collector, for field of renewable energy resource utilization.
Background technology
Tellurian resource and the energy are limited, and along with highlighting of energy shortage problem, exploitation new forms of energy, regenerative resource are 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 is a kind of renewable energy technologies the most ripe, that practical application can be competed with conventional energy resource at most and economically.
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.But water flows in passage, distance is short, can not fully absorb heat, and in-channel water turbulivity is low simultaneously, and discharge is little, and the problem that flow resistance is large is not resolved all the time.
Summary of the invention
The present invention is that this solar thermal collector has compact conformation in order to improve the existing weak point of above-mentioned prior art, a kind of flat-plate solar collector is provided, flow resistance is little, discharge is large, and heat exchange efficiency is high, and bearing capacity is strong, water is mobile distance in pipe, be easy to processing, the advantage such as with low cost, the holdup time that has overcome solar thermal collector water is in the past short, a little less than bearing capacity, the shortcoming such as heat transfer effect is poor.
The technical solution adopted in the present invention is: a kind of flat-plate solar collector, comprise water inlet 1, delivery port 2 and heat exchanger plates bundle 3, described heat exchanger plates bundle 3 is to be added together by two identical plate stacks, utilize laser penetration welding, two dull and stereotyped surroundings are welded and fixed, two dull and stereotyped inside are fixed by some inner bonding wires simultaneously, by pressurising between the inside bonding wire to adjacent, Formation cross-section is oval or oblate circulation canal 4, described circulation canal 4 is as aquaporin, described aquaporin and dull and stereotyped both sides are angled, be and be in tilted layout, extended the mobile distance of water in plate bundle, make water can be in plate bundle fully heat exchange, increase the turbulivity of in-channel water simultaneously, heat exchange strengthens, electroplating black chromium coating or other coating on the planar surface towards sunshine one side, increase dull and stereotyped heat storage capacity and the absorptivity to solar radiation, described heat exchanger plates bundle 3 one sides are provided with water inlet 1 and delivery port 2.
In the present invention, described flat board is to be made by higher metal materials of thermal conductivity factor such as stainless steel, copper or aluminium.
In the present invention, a water inlet 1, a delivery port 2 are at least set on described heat exchanger plates bundle 3.
The invention has the beneficial effects as follows:
Flat-plate solar collector compact conformation of the present invention, flow resistance is little, and discharge is large, and bearing capacity is strong, with low cost, is easy to processing, and water turbulivity in passage is high, and mobile distance and the flowing time of water in passage is long, and heat transfer effect strengthens, and heat exchange efficiency is high.

The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described in detail.
Embodiment 1: with reference to Fig. 1-2, heat exchanger plates bundle 3 is welded and fixed by some dull and stereotyped inside bonding wires 5 and dull and stereotyped surrounding bonding wire 6 by two relative flat boards, its middle plateform internal welding line 5 is angled with dull and stereotyped both sides.By pressurising, form circulation ellipse, oblate passage, as water circulation channel 4.On the flat board towards the sun one side, electroplate the coating of one deck black chrome coating or other increase plate absorptivities and heat storage capacity, can be used as the heat collector of solar water heater; Described heat exchanger plates bundle 3 one sides are provided with water inlet 1 and delivery port 2.
