GB is to freezing machine efficiency requirements, and bellows is more long.If patent name is that a kind of high-efficiency condensation heat exchanger, application publication number are
CN104296383A, Shen Qing Publication day are 015.01.21, the Application No. 2014105325777, applying date：It is 2014.10.10
A kind of high-efficiency condensation heat exchanger of disclosure of the invention, including housing, the blast pipe that is arranged on housing and be arranged in housing
Set of heat exchange tubes, the set of heat exchange tubes includes at least one heat exchanger tube, and the heat exchanger tube is a bellows, the heat exchanger tube folding
The reciprocal shape structure being made up of multiple straight tubes and multiple bend pipes is curved, straight tube and the flue gas flow direction in housing of the heat exchanger tube hang down
Directly, and described multiple straight tubes axis not in the same plane.The patent equally exists described problem.
The content of the invention
The purpose of the present invention proposes that a kind of elimination vibrates hidden danger aiming at the deficiencies in the prior art.Reducing material should
With the gas heater condensation heat exchange of heat pipe of the parallel-connection structure of reduces cost.
In order to reach object above, patent of the present invention is adopted the following technical scheme that：A kind of parallel gas heater condensation
Heat exchanger, including cavity and several bellowss being arranged in parallel for being arranged in cavity, the two ends of bellows are provided with bellows
Fixed disk, the end cap setting up and down of cavity, end cap forms two cells for being used for charge for remittance and point water, cavity with bellows fixed disk
There is flue gas to import/derive to import and export, condensed water collecting device, flue gas flow deflector are additionally provided with the cavity.
Used as the further improvement of such scheme, the small interior is provided with water guiding device.
Further, the condensed water collecting device is arranged on cavity wall, and lower end is connected with condensed water exit.
Further, the cavity is cylinder mode, and water inlet is arranged on the center of bottom end cover, small through bottom end cover
Each bellows is branched to after the charge for remittance of room, is flowed out from the delivery port of cavity sidepiece in the small indoor charge for remittance of upper end cover.
Further, the flue gas introducing port is arranged on the sidepiece of cavity, and flue gas export mouth is arranged on the top of cavity.
Compared with prior art, a kind of condensing heat exchanger that patent of the present invention is provided has the advantages that：
The present invention as a result of the structure of upper lower fixed disk, so that bellows will not vibrate fixation, shake by elimination
Dynamic hidden danger；Materials application is reduced simultaneously, can effective reduces cost.
By the way of tube bank is arranged side by side, resistance is smaller, and water-carrying capacity scope is wider for the present invention；Flue gas cross-flow tube bank, efficiency is more
Height, present invention employs the design of charge for remittance/Fen Shui cells cavity, can effectively solve the mixing efficiency of water temperature.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to patent of the present invention.
As Figure 1-3, the gas heater condensation heat exchange of heat pipe of parallel-connection structure of the invention includes cavity 6 and is arranged on
Several bellowss 10 being arranged in parallel in cavity 6, the two ends of bellows 10 are provided with bellows fixed disk 12, cavity 6 it is upper
Lower setting end cap, end cap forms two cells 5,7 for being used for charge for remittance and point water with bellows fixed disk, is set in the cell 7 of lower end
Water guiding device 11 is equipped with, condensed water collecting device is arranged on the wall of cavity 6, and lower end is connected with condensed water exit, and exit has
Condensation water swivel 1；Cavity 6 has flue gas to import/derivation import and export, and condensed water collecting device, flue gas are additionally provided with the cavity
Flow deflector 3, several bellowss 10 are welded on bellows fixed disk 12, then respectively with charge for remittance/Fen Shui cells 5,7 cavity weldings.
Heat exchange main body after welding is welded with cavity 6, outlet flue 4, smoke inlet 2, turnover water swivel, condensation water swivel 1.The cavity is
Cylinder mode, water inlet is arranged on the center of bottom end cover, and each bellows 10 is branched to after the charge for remittance of bottom end cover cell 7,
Charge for remittance flows out from the delivery port of cavity sidepiece in upper end cover cell 5.
The flue gas introducing port is arranged on the sidepiece of cavity, and flue gas export mouth is arranged on the top of cavity.
After flue gas enters from smoke inlet, the horizontal bellows group for skimming over cross arrangement under the obstruct of flue gas flow deflector, with ripple
Water in line pipe is discharged upwards after carrying out heat exchange from right side；
Current are entered by water inlet, and each bellows is branched in small interior, are flowed out again in other end charge for remittance；
