Problems solved by technology

Generally, there are two kinds of exhaust tailpipes, one is glass tailpipe, which is pre-sealed on the glass tube. The copper pipe is welded on the top cover for exhaust, and there is also a vacuum leak due to poor welding quality
At the same time, the existence of the tail pipe will also affect the appearance of the product
How to make a heat pipe vacuum heat collector without a tailpipe has not been broken through

Embodiment 1

[0037] see Figure 1a , Figure 1b , figure 2 , Figure 5 and Figure 6 Shown, its common point is all to be provided with metal sheet 3, difference is that the glass tube structure in each figure is different, a kind of manufacturing method of the heat pipe type vacuum heat collecting tube that does not have exhaust tailpipe, comprises the following steps, (a) Weld metal ring 1 on one end of glass tube 4 or glass tube 9; (b) Weld metal tube 2 on metal ring 1; (c) Place metal sheet 3 near the condensation section of heat pipe 5, metal sheet Solder is placed on the inner and outer rings of 3, respectively, and the evaporation section of heat pipe 5 is welded with selective absorption fins 6 in advance; (d) Insert heat pipe 5 into glass tube 4 or glass tube 9; (e) Glass tube 4 or glass tube 9 The other end of the tube 9 has a round bottom; (f) the metal tube 2 and the metal sheet 3 on the heat pipe 5 do not contact and maintain a gap, as an exhaust channel, insert them as a ...

Embodiment 2

[0041] The difference from Embodiment 1 is that no additional metal sheet 3 is required.

[0042] see image 3 , Figure 4 , Figure 7 and Figure 8 As shown, the difference is that the structure of the glass tube in each figure is different, a method of manufacturing a heat pipe vacuum heat collecting tube without an exhaust tail pipe, (a) welding metal on one end of the glass tube 4 or glass tube 9 Ring 1; (b) weld metal tube 2 on metal ring 1; (c) place solder directly on the condensation section of heat pipe 5, and weld selective absorption fins 6 in the evaporation section of heat pipe 5 in advance; (d) put heat pipe 5 Insert the glass tube 4 or glass tube 9; (e) the other end of the glass tube 4 or glass tube 9 has a round bottom; (f) the condensation section of the metal tube 2 and the heat pipe 5 does not contact and maintains a gap, which is used as an exhaust channel. They are inserted into the exhaust groove 8 as a whole for vacuum exhaust; (g) after the vacuum ...

Abstract

A method for manufacturing a heat pipe type vacuum heat collecting pipe without a tail pipe, and the vacuum heat collecting pipe manufactured by using the method. The manufacturing method comprises: (a) welding a metal ring (1) at one end of a glass pipe (4, 9); (b) welding a metal pipe (2) on the metal ring (1); (c) placing a metal sheet (3) at a part close to a heat pipe (5) condensation section, separately placing a solder at an inner ring and an outer ring of the metal sheet (3), or not placing the metal sheet (3) but directly placing the solder at the heat pipe (5) condensation section; (d) inserting a heat pipe (5) into the glass pipe (4, 9); (e) performing bottom rounding on the other end of the glass pipe (4, 9); (f) using the metal pipe (2) and the heat pipe (5) which do not contact with each other as an exhausting pipe, and integrally inserting the metal pipe (2) and the heat pipe (5) into an exhausting groove (8) for vacuumizing exhaust; (g) after the vacuumizing exhaust is ended, a mechanical apparatus (7) in the exhausting groove (8) pushing the heat pipe (5), so as to allow the metal pipe (2) to contact the metal sheet (3) or allow the heat pipe (5) condensation section where the solder is placed to contact the metal pipe (2); and (h) melting the solder outside the exhaust groove (8) in high-frequency heating mode, and sealing the heat pipe type vacuum heat collecting pipe. In the method, a tail pipe is not required to be welded in advance, and therefore, the production efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a manufacturing method of a heat pipe type vacuum heat collecting tube without an exhaust tail pipe and the vacuum heat collecting tube. technical background [0002] Among the many utilization methods of solar energy, photothermal utilization is to directly convert solar energy into thermal energy, which has high conversion efficiency and has been widely promoted and applied. At present, common photothermal utilization technologies include all-glass vacuum tube technology, flat plate collector technology, and heat pipe vacuum heat collector technology. Among them, the heat pipe type vacuum heat collector is obtained by sealing the heat pipe welded with selective absorption fins in the vacuum glass tube by metal sealing technology, and its light-to-heat conversion efficiency is the highest among the above three utilization forms. The current heat pipe ...
