Get up, it is ensured that the sealing of flue, while absorbing the relative displacement between tube bank and flue, this features simple structure is feasible, can push away
Extensively use.Prior art passes through the sealing device of flue not used for this kind of heat pipe bundle.
The content of the invention：
It is an object of the invention to provide the heat pipe seal and encapsulating method of a kind of flue.
Above-mentioned purpose is realized by following technical scheme：
A kind of heat pipe seal for flue, its composition includes：Expansion joint, described expansion joint is two ends with straight
The structure of bulging in the middle of section, described expansion joint one end straight section is welded on the walling of flue that heat pipe bundle is passed, described expansion joint
Sealing welding is carried out between other end straight section and heat pipe bundle with combed plate, one group of reinforcement is welded with described expansion joint straight section
Plate, one group of described reinforcement gusset is located between two pipes.
The described heat pipe seal for flue, described combed plate is placed on the topmost and foot of heat pipe bundle
Or be placed between heat pipe bundle, described topmost and foot combed plate one end are welded with the straight section of expansion joint, described comb
The perforate of template one end or both ends open and heat pipe bundle sealing welding.
The method sealed using the heat pipe seal of described flue, expansion joint is two ends with swollen in the middle of straight section
The structure for going out, expansion joint one end straight section is welded on the walling of flue that heat pipe bundle is passed, expansion joint other end straight section and heat pipe bundle it
Between sealing welding is carried out with combed plate, be welded with one group of reinforcement gusset at expansion joint straight section, strengthen gusset be located at two pipes it
Between in stove depth direction, be the straight section welded with flue at expansion joint straight section, at interval of two pipes because expansion joint size is big
Spacing, weld one section reinforcement gusset, gusset is strengthened herein, be evenly arranged along flue width, be divided into along short transverse
Three sections, it is arranged on inside the upper outside of expansion joint opening size, lower outside, expansion joint, for supporting expansion joint, it is ensured that swollen
Swollen section does not deform.
Beneficial effects of the present invention：
1. the present invention solves the relative displacement between flue and heat pipe bundle very well, and has taken into full account the strong of sealing device
Degree is required, there is provided strengthen gusset to be used to support expansion joint, it is ensured that expansion joint does not deform.Simple structure is effectively solved
Heat pipe bundle wears sealing and the expansion issues of flue.
