Description

technical field [0001] The invention relates to a production equipment for solar heat collecting tubes, in particular to a special equipment for filling superconducting heat transfer medium into the heat collecting tubes. Background technique [0002] The traditional in-line all-glass vacuum heat collecting tube water heater includes a vacuum heat collecting tube and an insulated water tank. The vacuum heat collecting tube is inserted into the insulated water tank, and the absorbed solar radiation is converted into heat energy by utilizing the high absorption rate and low emissivity of the vacuum heat collecting tube. , using the characteristics of large proportion of cold water and small proportion of hot water, a natural circulation of cold water from top to bottom and hot water from bottom to top is formed in the vacuum tube, so that the temperature of the whole water gradually rises to a certain temperature. However, this method of utilizing water to circulate in the vac...

However, this method of using water to circulate in the vacuum heat collecting tube to increase the temperature of the water has the problems of easy generation of scale and slow temperature rise.

[0003] In order to solve this problem, our company has introduced a new type of vacuum heat collecting tube. This new type of heat collecting tube includes a heat absorbing part and a heat exchanging part. The heat absorbing part includes an inner glass tube and an outer glass tube. The gap between the inner and outer glass tubes is The heat absorbing part is a single-layer glass tube. The heat absorbing part and the heat exchanging part are respectively provided with a blind end and an open end. The blind end is provided with an exhaust pipe for vacuuming. The heat absorbing part and the heat exchanging part The opening ends of the vacuum tubes are fused and sealed together, and the airtight space formed is evacuated and filled with an appropriate amount of superconducting heat transfer medium. At present, filling machines are generally used to fill superconducting heat transfer media into vacuum tubes. This method requires equipment investment. Large, operationally complex problems
