Abstract
The invention relates to a novel flat-plate solar heat collector comprising a water inlet, a water outlet and heat collection plate bundles. Corrugated plates are formed by punching of a hydraulic press and a die. Every two corrugated plates are superposed to form one plate bundle. A flow guide plates are arranged on the inlet and the outlet to the benefit to diffusion and outflow of water. Supporting bumps with certain heights are arranged in the pipe bundles and are in the shape of balls, plate intervals are formed by the heights of the bumps, and accordingly a corrugated water passage is formed. The water passage is in a novel structural form, so that flow distance of the water in the plate bundles is lengthened, the water can exchange heat in the plate bundles sufficiently, turbulivity of the water in the passage is improved, heat exchange is enhanced, and rigid strength and compressive strength of the heat collection plate bundles are enhanced by the aid of the bumps. A black chromium coating or other coating is electroplated on each plate sheet on one side facing the sunlight so as to increase heat storage capacity of the plate sheets and absorptivity of solar radiation. The novel flat-plate solar collector is compact in structure, simple to process, low in cost, easy to assemble and adjust, large in water flow, small in flow resistance and high in compressive strength and heat collection efficiency.
Description
Technical field
The present invention relates to a kind of novel flat-plate solar thermal collector, specifically a kind of design improvement of heat collectors for solar water heater.
Background technology
Along with modern industry and social development, the current limited resource step of development that is difficult to keep pace with the times, therefore develops new forms of energy, regenerative resource seems more very urgent.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 problems such as distance is short but water flows in passage, can not fully absorb heat, and in-channel water turbulivity is low simultaneously, and discharge is little, and flow resistance is large, and collecting plate bundle voltage endurance capability is poor are not resolved all the time.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and a kind of novel flat-plate solar thermal collector is provided, and this solar thermal collector has compact conformation, flow resistance is little, and discharge is large, and water is at channel flow distance, corrugated aquaporin strengthens turbulivity, and collecting efficiency is high, and bearing capacity is strong, be easy to processing, the advantage such as with low cost, has overcome in the past solar thermal collector water holdup time in passage short, and turbulivity is low, 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 novel flat-plate solar thermal collector, comprise water inlet 1, delivery port 2 and collecting plate bundle 3, described collecting plate bundle 3 is superimposed and is formed by two identical corrugated plating positioned opposite, described corrugated plating is evenly distributed with the support salient point of certain altitude, described support salient point becomes class spherical shape, adjacent support bump height forms distance between plates, thereby forms corrugated aquaporin-4; Collecting plate bundle 3 tops arrange water inlet 1, and bottom sets out the mouth of a river 2.Aquaporin adopts new version, 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, and the existence of supporting salient point has also increased rigid body intensity and the compressive resistance of collecting plate bundle.
In the present invention, described support bump height is 1 ~ 10mm.
In the present invention, described collecting plate bundle be in stainless steel, copper coin sheet or aluminum plate any.
In the present invention, a water inlet, a delivery port are at least set on collecting plate bundle.
In the present invention, towards electroplating black chromium coating or other coating on the corrugated cardboard sheet of sunshine one side, increase heat storage capacity and the absorptivity to solar radiation of plate.
Flat-plate solar collector reasonable in design of the present invention, this collector structure is compact, flow resistance is little, discharge is large, water is long in the passage holdup time, turbulivity is large, bearing capacity is strong, collecting efficiency is high, with low cost, is easy to processing.
Accompanying drawing explanation
Fig. 1 is collector structure figure of the present invention;
Fig. 2 is that Figure 1A-A is to cutaway view;
Fig. 3 is that heat collector of the present invention is overlooked partial sectional view;
Number in the figure: 1. water inlet, 2. delivery port, 3. corrugated aquaporin, 4. collecting plate bundle, 5. middle part sealing wire, 6. surrounding sealing wire.7. deflector.
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.
With reference to Fig. 1-2, collecting plate bundle supports salient point by two identical corrugated platings by several, the sealing wire 5 at some middle parts and the sealing wire 6 of plate Shu Sizhou are welded and fixed, and wherein the sealing wire 5 at middle part is parallel with the right and left of plate bundle, and its length is less than the corrugated plating left and right length of side.Place, heat collector gateway is all provided with the deflector 7 of some angles, is conducive to diffusion and the outflow of water.The support salient point that has certain altitude in plate bundle, salient point becomes class spherical shape, and bump height forms distance between plates, thereby forms corrugated aquaporin-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, as the heat collector of solar water heater.
The above is a kind of novel flat-plate solar thermal collector of the present invention, all within the spirit and principle of patent of the present invention, any modification of making, is equal to and replaces and improvement etc., within all should being included in the protection domain of patent of the present invention.
