Detailed description of the invention
Below in conjunction with Fig. 1, the invention will be further described.
Embodiment: a kind of gas industry boiler condensation formula heat exchanger, this heat exchanger is mainly handed over by upper strata heat
Change pipe 1 and lower floor's heat-exchange tube 2 form, described upper strata heat-exchange tube 1 and lower floor's heat-exchange tube 2 be all by
Many heat-exchange tube compositions arranged side by side, one end of described heat exchanger is provided with collecting box 10, and described upper strata heat is handed over
Change the water outlet end of pipe 1 to be connected by the water inlet end of collecting box 10 with lower floor heat-exchange tube 2.Described upper strata
It has been welded with fixing interconnection function between water outlet end and the mouth of a river end of lower floor's heat-exchange tube 2 of heat-exchange tube 1
Connection end plate, the end face of described collecting box 10 be connected end plate entirety expanded joint.Described upper strata heat-exchange tube 1
It is equipped with swollen 6 away from one end of collecting box 10 with lower floor heat-exchange tube 2.Described upper strata heat-exchange tube 1 He
Lower floor's heat-exchange tube 2 is additionally provided with catch 7, and described catch 7 is positioned at heat exchanger one end away from collecting box 10,
Catch 7 plays spacing and makes to connect between upper strata heat-exchange tube 1 and lower floor's heat-exchange tube 2 more firm effect.
Described upper strata heat-exchange tube 1 and lower floor's heat-exchange tube 2 by being all made up of several heat-exchange tubes arranged side by side,
Being extended monomer area, facilitate superposition to use, the heat-exchange tube of the present embodiment upper strata heat-exchange tube 1 is
The six roots of sensation, the heat-exchange tube of lower floor's heat-exchange tube 2 is seven, muzzle velocity water-flowing amount when increasing second, reduces U
The water resistance of type design, described heat-exchange tube is Nitinol pipe, and Nitinol pipe heat-conductive characteristic is excellent, and gram
Take the problem that disposable overall welding procedure is relatively difficult to achieve；Angle in described collecting box 10 is 15 degree
Cambered surface, collecting box 10 substitutes conventional u-shaped pipe connected mode, reduces water resistance, and described collecting box 10 includes
