Description

A kind of condensing heat exchanger

Technical field

The utility model belongs to gas instantaneous water heater technical field, and in particular to a kind of condensing heat exchanger.

Background technology

For existing condensing heat exchanger mostly using spiral circle coil arrangement, coil pipe form degree of freedom is big, should not shape, can not be effective The reasonable spacing between heat exchanger tube is kept, heat exchange pipe surface is insufficient with smoke contacts, influences heat transfer effect, increases heat exchange pipe range Degree；

Existing similar heat exchangers cavity is square structure, and coil pipe is cylinder, and flue gas flow rate variation in heat exchanger is caused to add Greatly, cavity quadrangle flue gas flow rate is high, and flue gas flow rate bottom, influences heat transfer effect among heat exchanger tube.

Existing condensing heat exchanger coil pipe is mostly free state after machining, and can not ensure the spacing between coil pipe, is used The variation of hydraulic pressure in the process is easily interfered with each other between coil pipe, is generated noise, is influenced product performance；

Utility model content

In view of this, the main purpose of the utility model is that providing a kind of condensing heat exchanger.

In order to achieve the above objectives, the technical solution of the utility model is realized in：

The utility model embodiment provides a kind of condensing heat exchanger, including smoke exhaust barrel, housing, matrix heat exchange coil, into Chimney, water inlet tap, water draining beak, condensate water discharging mouth, the matrix heat exchange coil be located at enclosure interior and lower end respectively with into Water nozzle, water draining beak connection, the arbitrary side in left and right of the housing and upside set smoke-input tube, smoke exhaust barrel, the condensed water respectively Water draining beak is located at housing bottom.

In said program, the matrix heat exchange coil is made of, and both ends are vertical a bellows with rectangular path coiling It is down-set；Water inlet tap, water draining beak are set respectively on the both ends of the matrix heat exchange coil.

In said program, be provided with spacing between the often circle coil pipe of the matrix heat exchange coil, and often circle coil pipe with Angle is provided between horizontal plane；The often circle coil pipe of the matrix heat exchange coil is fixed for ensureing that spacing is consolidated by restraining item It is fixed.

In said program, water inlet tap, the water draining beak of the matrix heat exchange coil are respectively positioned on same level.

In said program, the housing includes condensation housing, upper end cover, bottom end cover, and the upper end cover, bottom end cover are set respectively It puts in the top and bottom of condensation housing.

In said program, stent is additionally provided with for being fixed on inside equipment on the condensation housing.

Compared with prior art, it after the utility model high temperature flue gas is entered by the smoke-input tube in housing, then passes through It is discharged after crossing the cooling of matrix heat exchange coil by smoke exhaust barrel, meanwhile, the matrix heat exchange coil is realized by water inlet tap, water draining beak The alternating of coolant, in this way, under with equal volume, the heat exchanger area bigger of the utility model, exchange capability of heat is stronger；Instead It, under heat unanimous circumstances, the volume smaller of the utility model can bring cost to be carried with the apparent of complete machine craftsmanship It rises.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

The utility model embodiment provides a kind of condensing heat exchanger, as shown in figs. 1-7, including smoke exhaust barrel 1, housing 2, square Battle array heat exchange coil 3, smoke-input tube 4, water inlet tap 5, water draining beak 6, condensate water discharging mouth 7, the matrix heat exchange coil 3 are located at housing 2 Internal and lower end is connect respectively with water inlet tap 5, water draining beak 6, the arbitrary side in left and right of the housing 2 and upside set respectively into Chimney 4, smoke exhaust barrel 1, the condensate water discharging mouth 7 are located at 2 bottom of housing for discharging the condensation formed during high-temperature flue gas cooling Water；After high-temperature flue gas is entered by the smoke-input tube 4 in housing 2, pass through smoke exhaust barrel after cooling down using matrix heat exchange coil 3 1 discharge, meanwhile, the matrix heat exchange coil 3 realizes the alternating of coolant by water inlet tap 5, water draining beak 6.

As illustrated in figs. 5-7, the matrix heat exchange coil 3 is made of, and both ends are hung down a bellows with rectangular path coiling It is straight down-set；Water inlet tap 5, water draining beak 6 are set respectively on the both ends of the matrix heat exchange coil 3.

Further, it when being used cooperatively using matrix heat exchange coil 3 and rectangular housing 2, can effectively improve in heat exchange Flue gas flow rate uniformity improves heat transfer effect.

Spacing is provided between the often circle coil pipe of the matrix heat exchange coil 3, and often encloses coil pipe between horizontal plane It is provided with angle；The often circle coil pipe of the matrix heat exchange coil 3 is fixed for ensureing that spacing is fixed by restraining item 31, ensures square The spacing of battle array heat exchange coil 3 ensures that matrix heat exchange coil 3 can come into full contact with flue gas, improves heat exchange efficiency；The spacing energy It is interfered with each other when enough reducing heat exchanger by water impact, reduces the generation of heat exchanger flow noise.
