The invention adopts the following technical scheme:
big many curved surfaces of acceptance angle multithread way slot type solar energy air heat collector, its characterized in that: the solar heat collector comprises a multi-curved-surface reflecting groove body, three air heat collecting glass tubes, six spoke type stainless steel heat absorbing fins, a glass cover plate, a steel plate sealing plate, a glass sealing plate, a rectifying box and an intermediate connector;
the method is characterized in that: the air heat collection glass tube is made of a glass tube with the tube diameter of 110-125 mm, and six spoke type stainless steel heat absorption fins are arranged inside the air heat collection glass tube; the outer surfaces of the six-spoke type stainless steel heat absorption fins are plated with black chromium, the included angle of each fin is 60 degrees, the total number of the fins is 6, after the direct or reflected focused solar rays penetrate through the air heat collection glass tube, one part of the direct or reflected focused solar rays are directly absorbed by the six-spoke type stainless steel heat absorption fins, and the rest of the solar rays are absorbed by the adjacent fins after being reflected for the first time;
the design concept of three air heat collection glass tubes is adopted in the multi-curved surface reflection tank body, and the relative positions of the three air heat collection glass tubes in the multi-curved surface reflection tank body are as follows: the three tubes are not contacted with each other, and the mutual position relations are that the heights from the glass cover plate are respectively 215mm, 108.4mm and 198.4 mm; the distance from the center line to the center point of the uppermost air heat collecting glass tube is 60mm, the center point of the lowermost air heat collecting glass tube is located on the center line, and the distance from the center point of the middle air heat collecting glass tube to the center line is 140 mm.
The multi-curved-surface reflection tank body is formed by glass fiber reinforced plastic in a die-casting mode, the thickness of the multi-curved-surface reflection tank body is 3.5mm, the heat conductivity coefficient of the multi-curved-surface reflection tank body is 0.4W/(m DEG C), and a layer of specular reflection aluminum with the thickness of 0.6mm is pasted on the inner surface of the multi-curved-surface reflection tank body. The reflecting tank body is lighter in weight and better in heat preservation performance.
The opening of the multi-curved-surface reflection tank body is sealed by a glass cover plate with the thickness of 5 mm. The width of the opening of the multi-curved-surface reflection groove body is 0.66m, and the width of the glass cover plate is 0.7 m.
The air heat collection glass tube is supported and fixed by an end steel plate sealing plate at the port of the multi-curved-surface trough type heat collector, the upper part of the end steel plate sealing plate is connected with the end glass sealing plate, and two end plates are connected and sealed with the port of the multi-curved-surface trough type heat collector.
The air heat collection glass tube is made of a glass tube with the tube diameter of 110-115 mm, and six spoke type stainless steel heat absorption fins are arranged inside the air heat collection glass tube. The outer surface of the six-spoke type stainless steel heat absorption fin is electroplated with black chromium, the included angle of each fin is 60 degrees, the total number of the fins is 6, and the structural schematic diagram is shown in figure 1 a. The six-spoke type stainless steel heat absorption fin structure has the advantages that after the direct-irradiating or reflection-focusing solar rays penetrate through the air heat collection glass tube, one part of the direct-irradiating or reflection-focusing solar rays are directly absorbed by the six-spoke type stainless steel heat absorption fins, and the rest of the solar rays are absorbed by the adjacent fins after being reflected for the first time. Compared with the metal pore plate rolling plate in the document 1 (non-tracking double-heat-collecting tube multi-curved-surface groove type solar air collector, ZL201510085148.4), the heat collection efficiency of the six-spoke type stainless steel heat absorption fin can be improved by nearly 10%, and the six-spoke type stainless steel heat absorption fin is more corrosion-resistant and is not easy to age. Fig. 1 is a comparison of the present invention and the heat absorbing structure in the air heat collecting glass tube in document 1.
The design concept of three air heat-collecting glass tubes is adopted in the multi-curved-surface reflection tank body, and the relative positions (shown in figure 2) of the three air heat-collecting glass tubes in the multi-curved-surface reflection tank body are optimized and analyzed by adopting LightTools optical software based on a Monte Carlo ray tracing method, so that the light acceptance rate of the heat collector under different light receiving angles is optimal. The light receiving angle of the heat collector is within +/-40 degrees, and the optical convergence rate can reach more than 80 percent. FIG. 3 shows the law of the light acceptance rate of the collector as a function of the acceptance angle. Compared with the document 1, the invention can increase the air flow rate of the treatment by 50 percent, improve the receiving angle to more than 25 degrees, and simultaneously achieve the purpose of reducing the heat loss of the system to the outside because the air outlet temperature of the heat collector is more reasonable.
The connection mode of the large-receiving-angle multi-curved-surface multi-runner groove type solar air heat collector and an external air pipe is realized by connecting end steel plate seal plates at two sides with a rectifier box. The rectification box is a cavity designed according to the aerodynamic principle, and is used for combing turbulent flow caused by confluence or diversion of air by the three heat collecting pipes so as to reduce air flow resistance.
And the connection mode of two sets of the tracking-free multi-curved surface multi-runner trough type solar air heat collectors connected in series is the same as the phase ratio file 1.
The working process of the invention is as follows:
after sunlight is projected and penetrates through the glass cover plate and the end glass sealing plate of the large-receiving-angle multi-curved-surface multi-runner groove type solar air heat collector, one part of sunlight is directly projected onto the three air heat collecting glass tubes, and the other part of sunlight is reflected by the inner surface of the multi-curved-surface reflection groove body and focused onto the three air heat collecting glass tubes. After the direct or reflected focused solar rays penetrate through the air heat collecting glass tube, one part of the solar rays is directly absorbed by the six-spoke type stainless steel heat absorbing fins, and the rest of the solar rays are absorbed by the adjacent fins after being reflected for the first time. And the heated six-spoke type stainless steel heat absorption fins heat the air flowing through the air heat collection glass tube in a convection mode.
For low-temperature air needing to be heated, the low-temperature air firstly enters the tracking-free multi-curved-surface multi-runner groove type solar air heat collector through the rectifying box, and the heated hot air is connected with an external air pipe through the rectifying box. In addition, the multi-curved-surface solar air heat collector can be used as a unit assembly, or all the units are connected in series through an intermediate connector, or two ends of the unit assembly are connected with the rectifying box and then connected in parallel.
The invention has the beneficial effects that:
as shown in FIG. 4, the installation angle theta of the large-receiving-angle multi-curved-surface multi-runner trough type solar air heat collector is the solar altitude h at 12 pm in spring minutes1The altitude h of the sun at 9 am of the winter solstice2The included angle between the included angle bisector and the horizontal plane. When the heat collector is installed in Beijing, the solar altitude h of the heat collector at 12 o' clock at noon of spring-divided days in Beijing area1Is 40.1 degrees and the solar altitude h of 9 am in the winter solstice2At 8.2 °, the installation angle θ is 24 °, so that the amount of solar radiation received by the installation angle is hardly affected by the change of the solar altitude throughout the winter.
The light-gathering ratio of the heat collector is 3-5, and the optical efficiency is 0.8. When the length of the heat collector is 2m and the processing air flow is 0.03-0.06 kg/s, the instantaneous efficiency can reach 67-74%. Compared with the common single heat collecting pipe trough type air heat collector, the air flow heated by the air heat collector is improved by 1.5 times, the heat collecting efficiency can be improved by 9 percent, the structure is simple, the maintenance is convenient, and the market cost is reduced by 1/3. Fig. 5 and 6 are the results of the performance test of the heat collector of the present invention and the comparison document 1, respectively, in which the former improves the heat collection efficiency by 11.9% and the processing air flow rate by 50% compared with the latter.
