Abstract
The utility model discloses a high transmission solar water heater heat-collecting tube, wherein an outer pipe of the high transmission solar water heater heat-collecting tube is coated with a high transmission film, and the high transmission solar water heater heat-collecting tube is excellent in heat-collecting effect. The high transmission solar water heater heat-collecting tube is formed by sleeving an inner pipe and an outer pipe, wherein the inner pipe and the outer pipe are arranged coaxially, the diameter of the outer pipe is bigger than the inner pipe, and a vacuum layer is formed between the inner pipe and the outer pipe. The outer pipe is low emissivity (low-e) coated glass, is high in transmittance rate and has heat preservation effect. The high transmission solar water heater heat-collecting tube has the positive effects that the outer pipe is low-e glass, is high in transmittance rate and low in reflectivity, improves solar absorption rate, and is excellent in heat preservation effect.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, the high transmission thermal-collecting tube of solar water heater that particularly a kind of transmissivity is high.
Background technology
Solar energy is more and more favored at the energy as the energy of a kind of green, cleaning today in short supply day by day, and solar water heater is also because it is easy to use, and is stable, efficiently becomes huge numbers of families' selection.The main heat absorbing element of solar water heater is a thermal-collecting tube; What thermal-collecting tube was common at present is all glass vacuum heat collection tube of solar energy; This thermal-collecting tube is made up of inside and outside two concentric circles glass tubes, is pumped into high vacuum between the inner and outer pipes interlayer, and its shape is as an elongated inner flask; Inner bag with outside in the vacuum layer of courage the inner bag surface plated one deck black or blue-black metal heat-conducting rete, be used for absorbing the radiation in the sunlight.Its operation principle is that solar energy sees through outer glass and shines on the inner tube outer surface absorber and convert heat energy into; Heat the heat-transfer fluid in the inner glass tube then; Owing to vacuumized between the interlayer, effectively reduce the heat loss that ambient is scattered and disappeared, collecting efficiency is improved.Though this structure absorbs solar heat to a certain extent and prevents that heat scatters and disappears, the perspective rate of sunlight is lower, and solar energy can't be fully utilized.
The utility model content
The utility model technical problem to be solved provides a kind of outer tube and is coated with high transmittance film, the high transmission thermal-collecting tube of solar water heater that Heat-collecting effect is good.
For solving the problems of the technologies described above, the utility model is realized by following technical approach: the described high transmission thermal-collecting tube of solar water heater of the utility model is formed by interior pipe and outer tube fit.Interior pipe and outer coaxial tube, outer tube diameter forms vacuum layer greater than interior pipe between interior pipe and the outer tube.Outer tube is the low-e coated glass, and transmissivity is high and have a heat insulation effect.
The good effect of the utility model is: outer tube is a low-e glass, and perspective rate high reflectance is low, has improved solar absorptance and high insulating effect.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural principle sketch map of the utility model.
Among the figure, pipe in 1 outer tube, 2 vacuum layer 3
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is explained further details below in conjunction with the specific embodiment and accompanying drawing.At this, exemplary embodiment of the utility model and explanation thereof are used to explain the utility model, but not as the qualification to the utility model.
As shown in Figure 1, the described high transmission thermal-collecting tube of solar water heater of the utility model is formed with outer tube 1 fit by interior pipe 3.Interior pipe 3 is coaxial with outer tube 1, and outer tube 3 diameters form vacuum layer 2 greater than interior pipe 1 between interior pipe 3 and the outer tube 1.Outer tube 1 is the low-e coated glass, and transmissivity is high and have a heat insulation effect.
The good effect of the utility model is: outer tube is a low-e glass, and perspective rate high reflectance is low, has improved solar absorptance and high insulating effect.
Claims (2)
