Abstract
The utility model discloses a solar water heater heat collecting tube with reinforcing ribs. The solar water heater heat collecting tube structurally comprises an inner tube and an outer tube which are sleeved together. The inner tube and the outer tube are glass tubes and coaxial. The diameter of the outer tube is bigger than that of the inner tube. A vacuum layer is formed between the inner tube and the outer tube. The inner wall of the inner tube is plated with a selective absorption coating. The reinforcing ribs are disposed on the inner wall of the outer tube. The reinforcing ribs are a plurality of protrusions penetrating through the outer tube. The reinforcing ribs and the outer wall of the inner tube are integrally formed. The reinforcing ribs are evenly arranged along the inner wall of the outer tube. Further, the number of the reinforcing ribs can be determined according to the diameter of the outer tube and is generally within 7-22. The solar water heater heat collecting tube has the advantages that the protrusion structure on the outer tube can increase light concentrating effect and enhance heat collection effect of the inner tube in poor light. The protrusion structure of the outer tube plays a role of the reinforcing ribs, increases strength of the outer tube and enables the heat collecting tube to not be easy to damage.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, and particularly a kind of outer tube wall is provided with the protruding thermal-collecting tube of solar water heater that has reinforcement.
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 stable, once mounting is used for many years, and high-efficiency cleaning is pollution-free and become 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, and under the situation of morning and evening sunlight deficiency, is difficult to effectively solar energy absorbed, intensity is also not enough high in addition, damages easily.
The utility model content
It is good that the utility model technical problem to be solved provides a kind of Heat-collecting effect, can effectively absorb the high non-damageable thermal-collecting tube of solar water heater that has reinforcement of solar energy and intensity.
For solving the problems of the technologies described above, the utility model is realized by following technical approach: the described thermal-collecting tube of solar water heater that has reinforcement of the utility model is formed by interior pipe and outer tube fit; Interior pipe is a glass tube with outer tube, and interior pipe and outer coaxial tube, outer tube diameter form vacuum layer greater than interior pipe between interior pipe and the outer tube; Inner tube wall is coated with coating for selective absorption; Outer tube wall is provided with reinforcement, and reinforcement is the convexity of some perforation outer tubes, and reinforcement and outer tube wall are integrally formed, and reinforcement evenly distributes along outer tube wall.
Further, the number of reinforcement can be according to the outer tube diameter setting, and number can be between 7-22 usually.
The good effect of the utility model is: the bulge-structure on the outer tube can increase the optically focused effect, the Heat-collecting effect of pipe in insufficient light, can strengthening; The effect of its reinforcement of bulge-structure of outer tube has increased the intensity of outer tube, makes thermal-collecting tube not fragile.
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 3 reinforcements in 1 outer tube 2
4 vacuum layer
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 said thermal-collecting tube of solar water heater that has reinforcement of the utility model is formed with outer tube 1 fit by interior pipe 2; Interior pipe 2 is a glass tube with outer tube 1, and interior pipe 2 is coaxial with outer tube 1, and outer tube 1 diameter forms vacuum layer 4 greater than interior pipe 2 between interior pipe 2 and the outer tube 1; Interior pipe 2 inwalls are coated with coating for selective absorption; Outer tube 1 inwall is provided with reinforcement 3, and reinforcement 3 is the convexity of some perforation outer tube 1 inwalls, and reinforcement 3 is integrally formed with outer tube 1 inwall, and reinforcement 3 evenly distributes along outer tube 1 inwall.
Further, the number of reinforcement 3 can be according to outer tube 1 diameter setting, and number can be between 7-22 usually.
The good effect of the utility model is: the bulge-structure on the outer tube can increase the optically focused effect, the Heat-collecting effect of pipe in insufficient light, can strengthening; The effect of its reinforcement of bulge-structure of outer tube has increased the intensity of outer tube, makes thermal-collecting tube not fragile.
