Abstract
The utility model relates to a solar-energy absorption apparatus and in particular relates to a solar-energy heat absorption plate and concretely relates to a heat absorption plate core for an all-aluminium micro-channel solar heat collector. The plate core comprises two liquid collecting pipes, wherein the two liquid collecting pipes are vertically arranged in parallel and communicated with each other through a plurality of calandrias and are aluminium circular pipes. The calandrias are formed by that a plurality of aluminium flat pipes are mounted with each other and welded together. A coating absorbing solar energy covers on an external surface of the aluminium flat pipes. A heat conduction liquid is in the aluminium flat pipe and is used for heat transfer, thereby saving two times of heat transmission, reducing more than 20% heat loss and raising heat transfer efficiency. The heat absorption plate core has the advantages that processing cost is low, heat absorption area is large, the plate core can fully absorb solar energy heat and has a relatively high economic value.
Description
Technical field
The utility model relates to solar energy absorption plant, especially a kind of solar heat baffle, specifically a kind of full aluminium microchannel solar thermal collector heat-absorbing plate core.
Background technology
What the panel solar heat-absorbing plate core generally used at present is that the copper coin pipe is as comb and collector tube pipe, about the every general 100mm of comb spacing.The inner filling has conductive fluid.Laser weld absorption film on the copper coin pipe of lattice-shaped also has part to use ultrasonic welding process.The absorption film matrix is generally the thick aluminium sheet of 0.4mm.The technology of existing product has following deficiency:
1. copper material exists cost high as precious metal with respect to aluminium, the problem of shortage of resources.Along with the development of present science and technology and process technology, a lot of industries all occur with the situation of aluminium for copper.
2. heat transfer aspect, process heat passes to the copper pipe at 100mm place by the 0.4mm absorption film at present, by the medium of interrupted pad with heat transferred copper pipe inside, conducts heat by the medium circulation of copper pipe inside again.
3. the laser welding process of the absorption film of commonly using at present is the not high problem of average life also, and copper aluminium material matter itself just exists the thermal coefficient of expansion difference during day and night temperature Datong District.The corrosion that adds the heavy butt welding point of absorber plate inner moisture is also large.The adhesion at solder joint place descends after general 5 years, and heat-transfer capability also can reduce greatly.
The ultrasonic welding process processing difficulties has damage to the absorption film surface simultaneously, can reduce whole endotherm area.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of full aluminium microchannel solar thermal collector heat-absorbing plate core is provided, and uses aluminium to replace copper material, reduces cost, weight reduction, and reduce the heat transfer link, improved heat transfer efficiency.
The technical solution of the utility model is: a kind of full aluminium microchannel solar thermal collector heat-absorbing plate core, the plate core comprises two up and down collector tubes of parallel placement, be communicated with by some combs between the collector tube, described collector tube is the aluminum pipe, and comb is that some aluminium flat conduits are mutually arranged and welded together; Described aluminium flat conduit outer surface is covered with the coating that one deck absorbs solar energy.
For guaranteeing its weld strength and welding quality, Welding is adopted in described aluminium flat conduit and aluminum pipe junction.
In order directly to absorb solar heat, described coating is for electroplating the absorption film on aluminium flat conduit.
The beneficial effects of the utility model are by as can be known above-mentioned, because adopting described collector tube is the aluminum pipe, comb is that some aluminium flat conduits are mutually arranged and welded together, the copper coin pipe that uses the aluminium flat conduit parallel array to arrange and replaced present compartment, welding between the aluminum pipe is more firm, long service life.And directly directly plate absorption film on the aluminium flat conduit surface, aluminium flat conduit inside is directly walked conductive fluid and is conducted heat, and saves heat transfer twice, can reduce heat waste more than 20%, has improved heat transfer efficiency.Processing cost of the present utility model is low, and endotherm area is large, can fully absorb the heat of solar energy, makes it have higher economic worth, meets the requirement of advocating energy-conserving and environment-protective.Can draw thus, the utlity model has certain progressive and practicality, very large popularizing value is arranged.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is the cross section structure schematic diagram of aluminium flat conduit.
Wherein, 1. collector tube, 2. pad, 3. aluminium flat conduit, 4. absorption film.
The specific embodiment:
In order to understand better the utility model, explain in detail embodiment of the present utility model below in conjunction with accompanying drawing.
The specific embodiment: as shown in Figure 1, 2, a kind of full aluminium microchannel solar thermal collector heat-absorbing plate core, the plate core comprises two up and down collector tubes 1 of parallel placement, be communicated with by some combs between the collector tube 1, described collector tube 1 is the aluminum pipe, comb is that some aluminium flat conduits 3 are arranged Welding together mutually, has so just formed the passage of a circulation.The more smooth outer surface of described aluminium flat conduit 3 one sides is covered with absorption film 4 coatings that one deck absorbs solar energy, as shown in Figure 3.A kind of heat transfer medium of inner can after installing.Absorption film 4 has absorbed heat and has been directly passed to circulatory mediator, and circulatory mediator is brought heat into water that water tank passes to again needs heating, has reduced the loss that heat is transmitted in different medium.
