Summary of the invention: technical problem to be solved in the utility model be to provide a kind of in big flow gas heater the heat exchanger of enhanced heat exchange, it can satisfy on the basis of performance requirement, improve heat exchange property effectively, make gas heater under identical rated heat input, rated heat load, reduce the usage quantity of fin, shortening heat interchanger length, thereby the use of minimizing copper, the cost of reduction gas heater.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high temperature section heat exchanger, it comprises main heat exchanger, tank shell, main heat exchanger contains tube bank and fin, and be fixed on the burner top, it is characterized in that it also comprises supplementary heat exchanger, flue gas spoiler, described supplementary heat exchanger contains tube bank and fin, the tube bank of main heat exchanger and supplementary heat exchanger is one deck tube bank, the flue gas spoiler is fixed on the tank shell inwall and is positioned at the top of main heat exchanger, and supplementary heat exchanger is fixed on flue gas spoiler top.
The length of the fin gas approach end of described supplementary heat exchanger is than the long 0.5-10mm of length of the fin gas approach end of main heat exchanger.
The length of the fin gas approach end of described supplementary heat exchanger is than the long 2-5mm of length of the fin gas approach end of main heat exchanger.
The fin transversion malposition of the fin of described main heat exchanger and supplementary heat exchanger is arranged.
Described main heat exchanger, supplementary heat exchanger are welded by copper or aluminium alloy or stainless steel material.
Described main heat exchanger be installed in burner directly over, the flue gas spoiler be installed in main heat exchanger directly over, supplementary heat exchanger be installed in the flue gas spoiler directly over.
The plates that described flue gas spoiler is made by stainless steel material are welded, and are fixed on the tank shell inwall by welding or riveted joint or screw.
The utility model is compared the beneficial effect that is produced with background technology:
Because adopting, the utility model is divided into two independently heat exchangers by original two-layer tube bank at the high temperature section heat exchanger, put into the flue gas spoiler in the centre, change the angle that the velocity of flue gas field enters supplementary heat exchanger, make velocity field vertical with thermoisopleth, improve flue gas heat exchange in the velocity field of supplementary heat exchanger and the overall coordination degree in temperature field, thereby heat convection is strengthened, improve heat exchange property, make gas heater under identical rated heat input, rated heat load, reduce the quantity of fin, shortening heat interchanger length reduces the use of copper, reduces the cost of gas heater.

The specific embodiment:
Shown in accompanying drawing 1, accompanying drawing 2, present embodiment comprises shell 1, first magnetic valve 2, second magnetic valve 3, burner assembly 4, main heat exchanger 5, flue gas spoiler 6, supplementary heat exchanger 7, exhaust fume collecting hood assembly 8, pulse igniter 9, blast switch 10, Switching Power Supply 11, blower fan assembly 12, controller 13, tank shell 14.Main heat exchanger 5 adopts one deck tube bank, be installed in directly over the burner 4, flue gas spoiler 6 is made by exotic material, as stainless steel material, is installed in directly over the main heat exchanger 5, flue gas spoiler 6 is fixed in the tank shell 14, supplementary heat exchanger 7 adopts one deck tube bank, is installed in directly over the flue gas spoiler 6, and high-temperature flue gas enters supplementary heat exchanger 7 through main heat exchanger 5 and flue gas spoiler 6, exhaust fume collecting hood assembly 8 is installed in supplementary heat exchanger 7 tops, and flue gas is outside exhaust fume collecting hood assembly 8 discharge machines.
The principle of described high temperature section heat exchanger: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, water heater normally starts, 12 work of blower fan assembly, controller 13 control impuls igniters 9 discharge ignitings, magnetic valve 2, magnetic valve 3 are opened simultaneously, and combustion gas enters the fire row burning of burner assembly 4 through each nozzle.High-temperature flue gas through flue gas spoiler 6, makes velocity field vertical with thermoisopleth after flowing out through main heat exchanger 5 heat exchange, improves flue gas heat exchange in the velocity field of supplementary heat exchanger 7 and the overall coordination degree in temperature field, thereby heat convection is strengthened.By prolonging the fin 71 gas approach end length (being D1) of supplementary heat exchanger 7, the length (being D1) of fin 71 gas approach ends that makes supplementary heat exchanger 7 is than the long 0.5-10mm of length (being D2) of the fin 51 gas approach ends of main heat exchanger 5, as 2mm, 5mm, 8mm, the area that makes the flue gas front wash away heat exchanger increases, hot-fluid is higher, thereby heat convection is strengthened.By the fin 51 of main heat exchanger 5 is arranged with fin 71 transversion malpositions of supplementary heat exchanger 7, the flue gas that flows out main heat exchanger 5 is divided right and left laterally to stream, thereby heat convection is strengthened, improve heat exchange property, make gas heater under identical rated heat input, rated heat load, reduce the usage quantity of fin, shortening heat interchanger length, reduce the use of copper, reduce the cost of gas heater.
