Preferably, in the heat-exchange tube of rectangular array, have at least a heat extraction exchanging tube to connect and compose heat exchanger plate by flue gas guide plate, on this flue gas guide plate, be provided with exhaust gases passes.
Preferably, each heat extraction exchanging tube all connects by flue gas guide plate.
Preferably, described exhaust gases passes is arranged on one end of flue gas guide plate.
Preferably, described exhaust gases passes is crisscross arranged on adjacent two heat exchanging fins.
Preferably, the both sides, front and back of described heat exchanger plate are also provided with side plate, and the adjacent side plates splicing that is positioned at the same side connects.
Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
1, the utility model uses many heat-exchange tubes to replace single heat-transfer pipe of the prior art, once single heat-exchange tube damages, can directly change.
2, in the utility model, heat-exchange tube is become matrix to arrange, utilize switching tank that heat-exchange tube is connected, to extend the length of heat-exchange tube, same row's heat-exchange tube is heated evenly, and feedwater heating more has bar order.
3, every heat extraction exchanging tube connects into heat exchanger plate by flue gas guide plate, on flue gas guide plate, exhaust gases passes is set, and flue gas guide plate has the effect that hinders flue gas circulation, makes the time of staying of flue gas in heat exchanger longer, and rate of heat exchange is higher.
4, exhaust gases passes is crisscross arranged, and has extended the passage of flue gas at heat-exchange tube, makes the time of staying of flue gas in heat exchanger longer, and rate of heat exchange is higher.
5, the both sides, front and back of heat exchanger plate arrange side plate, and the adjacent side plates splicing that is positioned at the same side connects, and forms the front and rear wall of heat exchanger, and exhaust gases passes is sealed more, and meanwhile, this sidewall can also reduce flue gas heat and scatter and disappear, and improves heat utilization ratio.

detailed description of the invention
Describe below in conjunction with accompanying drawing and a specific embodiment.
Referring to Fig. 1 to Fig. 8, in accompanying drawing, each mark title is as follows respectively: 10 switching water tanks, 11 installing holes, 12 switching tanks, 13 turnover tanks, 14 water receiving pipes, 20 heat-exchange tubes, 21 flue gas guide plates, 22 exhaust gases passes, 23 side plates.
The described high-effect heat exchanger of the present embodiment, two heat-exchange tubes 20 that the switching water tank 10 that is parallel to each other is arranged with many rectangular arrays that are connected two switching water tanks about comprising.The structure of two switching water tanks 10 is identical, and one of them switching water tank is positioned at water inlet end, and another switching water tank is positioned at water side.The interior plate of switching water tank 10 is provided with the installing hole 11 for heat-exchange tube is installed, on outer panel, be provided with water receiving pipe 14, in switching water tank, be horizontally disposed with multiple switching tanks 12 and a turnover tank 13, the present embodiment provides the situation of four switching tanks 12.Water receiving pipe 14 is communicated with turnover tank 13.Switching tank 12 is for being connected in series heat-exchange tube, and adjacent two heat extraction exchanging tubes are together in series.Installing hole 11 is for heat-exchange tube 20 is installed, and this installing hole 11 is communicated with switching tank 12 or turnover tank 13, and after heat-exchange tube 20 is installed, heat-exchange tube 20 is communicated with switching tank 12 or turnover tank 13.Turnover tank 13 connects a heat extraction exchanging tube, and switching tank 12 connects two heat extraction exchanging tubes.Water receiving pipe 14 is communicated with turnover tank 13.Be arranged on the switching water tank 10 of water inlet end, its turnover tank 13 is positioned at switching water tank 10 bottoms, and the effect that now passes in and out tank 13 is intake chamber, and water receiving pipe is water inlet pipe; Be arranged on the switching water tank 10 of water side, its turnover tank 13 is positioned at the top of switching water tank 10, and the effect that now passes in and out tank 13 is effluent trough, and water receiving pipe is outlet pipe.Cold water enters intake chamber from water inlet pipe, then enters a switching tank of water side by end heat extraction exchanging tube, and water enters a upper heat extraction exchanging tube by serial connection tank, by that analogy, finally enters effluent trough, and flows out from outlet pipe.Water is all heated when through every one deck heat-exchange tube.Water is heated in each heat extraction exchanging tube, and enters a heat extraction exchanging tube after mixing in switching tank again.Here a said upper heat extraction exchanging tube positions from upper and lower orientation.
