Abstract
The utility model discloses a high efficiency heat-collecting vacuum tube, including an inner glass tube and an outer glass tube; and a vacuum layer is disposed between the inner glass tube and the outer glass tube. The utility model is characterized in that an outer wall of the inner glass tube is tightly bonded with a middle portion of a heat absorption metal sheet through a heat conduction glue layer; and two side portions of the heat absorption metal sheet are turned out to form heat absorption fins. The utility model has high heating speed, good heat insulation effect, simple manufacturing process and low investment cost.
Description
Technical field
The utility model relates to technical field of solar water heaters, specifically is a kind of efficient heat-collecting vacuum tube.
Background technology
A kind of important form is a solar thermal utilization in the solar energy utilization now, the traditional vacuum thermal-collecting tube mainly be on inner layer glass tube, aluminize, metal such as copper is as absorbed layer, absorbs solar heat.
The main flow vacuum heat collection pipe mainly is the plated film heat absorption on inner pipe top layer at present.Its shortcoming mainly is: 1, the coat of metal on the inner pipe of vacuum tube top layer its absorption area that absorbs heat is subjected to the restriction of inner tube diameter.2,,, the restriction of its circle coating process is difficult to have again breakthrough because making its absorbent properties reach bottleneck because absorbed layer is a plated metal.And the present invention has well solved above problem.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of efficient heat-collecting vacuum tube, and its heats up fast, high insulating effect and manufacture craft is simple, input cost is low.
For addressing the above problem, the utility model is by the following technical solutions: this efficient heat-collecting vacuum tube, comprise inner glass tube, outer glass pipe, be provided with vacuum layer between described inner glass tube, the outer glass pipe, mid portion by a heat-conducting layer and a heat absorption sheet metal on the outer wall of described inner glass tube closely is pasted together, and the two side portions of described heat absorption sheet metal is routed up and formed the heat absorption fin.
As further technical scheme of the present utility model:
In this efficient heat-collecting vacuum tube, described heat absorption fin is for being bent downwardly and becoming 30 ° of angles with horizontal plane.
In this efficient heat-collecting vacuum tube, the upper surface of described heat absorption sheet metal is provided with the solar selectively absorbed layer.
In this efficient heat-collecting vacuum tube, the outer surface of described inner glass tube is coated with metallic reflector.
The beneficial effects of the utility model are:
1, the metallic character of heat absorption sheet metal has guaranteed efficient transfer of heat.
2, the heat absorption fin adopts sheet metal to make, and the solar selectively absorbed layer of heat absorption fin surface has guaranteed its high-absorbable energy.
3, the heat absorption fin has increased endotherm area greatly, and its effective endotherm area has increased more than 10%.The angle of bend setting of heat absorption fin has guaranteed that the incidence angle of sunray guarantees effectively to have reduced the generation of total reflection in suitable scope, has further promoted the efficient utilization rate of sunlight, has improved the intensification effect greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cross section structure for amplifying schematic diagram of the utility model embodiment;
Among the figure: 1 inner glass tube, 2 outer glass pipes, 3 heat absorption sheet metals, 31 heat absorption fins, 4 heat-conducting layers, 5 solar selectively absorbed layers, 6 metallic reflectors.
The specific embodiment
As shown in Figure 1 and Figure 2, this efficient heat-collecting vacuum tube comprises inner glass tube 1, outer glass pipe 2, and two-layer glass tube with vacuum all adopts high-transmission rate glass to make.Be provided with vacuum layer between described inner glass tube 1, the outer glass pipe 2.Vacuum layer plays heat insulation effect, reduces scattering and disappearing of heat.
The outer surface of described inner glass tube 2 is coated with metallic reflector 6.Mid portion by a heat-conducting layer 4 and a heat absorption sheet metal 3 on the outer wall of inner glass tube 1 closely is pasted together, and heat-conducting layer 4 guarantees the high-efficiency heat conduction effect.The two side portions of described heat absorption sheet metal is routed up and is formed heat absorption fin 31.Because the heat absorption sheet metal is arranged between the inside and outside glass tube, the caliber of outer glass pipe has determined the area of heat absorption sheet metal, i.e. endotherm area is so broken away from the constraint of inner glass tube.Described heat absorption fin 31 is for being bent downwardly and becoming 30 ° of angles with horizontal plane, as shown in Figure 2, the angle of bend setting of its heat absorption fin has guaranteed that the incidence angle of sunray guarantees effectively to have reduced the generation of total reflection in suitable scope, further promote the efficient utilization rate of sunlight, improved the intensification effect greatly.
The upper surface of described heat absorption sheet metal 3 is provided with solar selectively absorbed layer 5.This solar selectively absorbed layer 5 can also can prepare by applying by dull and stereotyped coating technique preparation.This solar selectively absorbed layer has guaranteed its high-absorbable energy.
