The birth of the drones "dronies" is a best example of people constantly breaking through and seeking new development. Innovative people use various technologies to develop new features of drones through high technology.
"To tell the truth, it has been impossible for any previous new unmanned aerial film to make any new progress," said Alexandra Dao, manager of the video site and Vimeo community. But the reality is moving in a dramatic direction. About two months ago, he saw a video of a high-tech entrepreneur Amit Gupta published on a video site. “I noticed that using drones has greatly improved photography and movie production. The new function of drones can bring many more professional shots to movies during filming.†When drones rise in the film, we can see many ancient towering trees more clearly. This can not only bring more and better visual enjoyment to the audience, but also can be a driving force for innovation enthusiasts, allowing science and technology to further bring benefits to us.
The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.
