The main vacuum tube products currently produced are: 47 and 58mm diameter
The length of 47 diameter tube is 1.2 meters/1.5 meters/1.6 meters /1.7 meters/1.8 meters
The length of pipe diameter 58 is 1.5m/1.6m/1.8m/2.0m/2.1m /2.2m
How thick and long is the Huangming Solar 18tt18 pipe
Current market The longest vacuum tube of mature solar water heaters is 2 .1 meters long.
The long vacuum tube water heater has good heat collection effect, rapid temperature rise, good heat preservation effect, and can reach higher temperatures with the same light. However, due to the complexity of the technology, production difficulties and high cost, most manufacturers have failed to develop it. Only one manufacturer has achieved mass production.
Size of 18 tube solar water heater bracket
TheHuangming Solar 18tt18 tube length is 1.8 meters, the outer diameter is 5.8 cm, and the inner diameter is 3.7 cm. According to the petition, relevant information shows: The Huangming Solar 18tt18 tube is a thermal superconductor and is the most efficient heat transfer element currently available to man. The starting temperature of the heat pipe is low and the heat exchange speed is fast in winter. Therefore, the length of the Huangming Solar 18tt18 tube is 1.8 meters, with an outer diameter of 5.8cm and an inner diameter of 3.7cm.
The most common specifications of this type of bracket type solar power are: the diameter of the vacuum tube is 58mm and the length is 1.6 meters, 1.8 meters and 1 .92 meters. see vacuum tubes with a length greater than 2 meters. The diameter of the vacuum tube is 47mm. This is a product manufactured at least three years ago. Don't buy it, otherwise there will be no replacementacement of the same diameter. the tube breaks.
