According to the embodiment of the heat exchange assembly provided by the invention, the heat exchange assembly comprises a smoke outlet assembly and a combustor. The burner is operable to increase the temperature of the fluid in the water line of the smoke outlet assembly.
Furthermore, the water pipeline can be wound on the smoke outlet pipe, then the fluid in the water pipeline is heated by the burner, and finally the fluid flows out from the discharge end of the water pipeline for users to use. The temperature of the flue gas discharged from the flue gas outlet pipe is high because a part of heat is taken away by the flue gas discharged from the burner when the burner burns the fuel gas, generally speaking, the fluid coiled in the water pipeline outside the flue gas outlet pipe is tap water flowing in directly through the water inlet pipe, and the temperature of the fluid is normal temperature, so that the temperature of the fluid is lower relative to the temperature of the flue gas, and through heat transfer, the temperature of the fluid is increased, and the temperature of the flue gas in the flue gas outlet pipe is correspondingly reduced. That is to say, the mode of water-gas heat exchange is adopted, the water pipeline is not in direct contact with the flue gas, the flue gas in the smoke outlet pipe is used for preheating the fluid in the water pipeline, and the fluid in the water pipeline coiled outside the smoke outlet pipe can also cool the flue gas with higher temperature. The number of turns of coiling of the water pipeline outside the smoke outlet pipe is increased, the temperature of the smoke discharged from the smoke outlet pipe can be effectively reduced, and the temperature of the smoke outlet pipe can be controlled within a safe range, so that the possibility that objects around the smoke outlet pipe are deformed by high temperature due to overhigh temperature of the smoke outlet pipe, even fire disasters are caused can be reduced, and the safety of the installation environment is improved.
Furthermore, as the fluid in the water pipeline is preheated by the smoke of the smoke outlet pipe, the fluid is heated by the burner after the temperature is increased to a certain degree, and the waste heat of the smoke is fully utilized, the heat exchange efficiency of the whole machine is improved.
Further, the fluid first flows through a partial water passage wound around the outside of the smoke outlet pipe and then is discharged through a partial water passage passing through the heat exchanger. Namely, the fluid is preheated by the smoke of the smoke outlet pipe, then is heated by the burner and finally is discharged for users to use. The preheated fluid has an increased temperature compared to the previous fluid, and can reach the temperature preset by the user more quickly through the burner. Therefore, in the whole process, the heating efficiency of the fluid is improved, the temperature of smoke in the smoke outlet pipe is reduced, and the safety of the installation environment is improved.
In the above technical scheme, the fan of the smoke outlet assembly is arranged at one end of the burner, which is far away from the smoke outlet pipe.
In this technical scheme, the fan setting is kept away from the one end of going out the tobacco pipe at the combustor to gas and air can carry out abundant mixture before the burning. Because the fan and the smoke outlet pipe are arranged on two sides of the combustor, the air outlet of the fan can blow most of smoke in the shell to be discharged from the smoke outlet pipe quickly and timely, and the shell is effectively cooled.
In addition, the embodiment of the heat exchange assembly provided by the invention has all the beneficial effects of the embodiment of the first aspect because the smoke outlet assembly in any one of the embodiments is arranged, and the details are not repeated herein.
Embodiments of a third aspect of the invention provide a hot water appliance comprising a housing; the heat exchange assembly in any embodiment is arranged in the shell, and the smoke outlet pipe of the heat exchange assembly is communicated with the inside of the shell and the outside of the shell.
According to an embodiment of the water heating device provided by the invention, the water heating device comprises a shell and a heat exchange assembly. The heat exchange assembly is arranged in the shell, and the smoke outlet pipe is communicated with the inside and the outside of the shell.
Furthermore, because some water pipelines can be coiled outside the smoke outlet pipe, most of heat in the smoke outlet pipe can be taken away by fluid coiled in the water pipelines of the smoke outlet pipe, and a small part of heat can be brought into the shell through gas entering through a gap between the outer pipe and the inner pipe, but the temperature in the shell is not very high.
Can be equipped with the fan in the casing, the fan when the operation, not only can drive the continuous casing that flows in of air and gas, promotes the burning, and the flue gas that the burning produced can in time be discharged by a tobacco pipe moreover, can take away most heats in the casing, reduces the internal bulk temperature of casing, reduces the air temperature in the casing and too high influences the life of electrical part.
In the above technical solution, the method includes: the heat exchanger is arranged in the shell corresponding to the burner, part of the water pipeline penetrates through the heat exchanger, fluid flows through part of the water pipeline of the smoke outlet pipe and then flows out through part of the water pipeline of the heat exchanger, and the burner can heat the heat exchanger by burning gas.
In the technical scheme, the heat exchanger is arranged in the shell and corresponds to the combustor. Part of the water passage passes through the heat exchanger, and the burner heats the heat exchanger by burning gas, so that the heat exchanger can transfer heat to the fluid in the water passage, that is, the burner heats the fluid in the water passage passing through the heat exchanger during operation.
Further, the fluid first flows through a partial water passage wound around the outside of the smoke outlet pipe and then is discharged through a partial water passage passing through the heat exchanger. Namely, the fluid is preheated by the smoke of the smoke outlet pipe, then is heated by the burner and finally is discharged for users to use. The preheated fluid has an increased temperature compared to the previous fluid, and can reach the temperature preset by the user more quickly through the burner. Therefore, in the whole process, the heating efficiency of the fluid is improved, the temperature of smoke in the smoke outlet pipe is reduced, and the safety of the installation environment is improved.
Further, because the fluid is preheated by the flue gas passing through the smoke outlet pipe before entering the heat exchanger, the temperature of the fluid entering the heat exchanger is increased compared with the prior temperature, and the temperature of the heat exchanger is correspondingly increased through heat transfer, so that the temperature difference between the wall surface of the heat exchanger and the flue gas with higher temperature is reduced. The flue gas generated by combustion contains partial water vapor, particles and other substances, so that the temperature difference between the wall surface of the heat exchanger and the flue gas is reduced, and the flue gas generated by combustion can be kept at a temperature higher than the dew point temperature when contacting the wall surface of the heat exchanger. The dew point temperature is the temperature at which the water vapor and the water reach an equilibrium state, and when the actual temperature is higher than the dew point temperature, the air is not saturated, so that the generation of condensed water is limited. That is, if the flue gas generated by combustion is kept at a temperature higher than the dew point temperature even after contacting the wall surface of the heat exchanger having a relatively low temperature, the water vapor in the flue gas is not condensed and harmful particles are not retained in the casing by the condensed water. Thus, it is possible to ensure a reduction in the generation of condensed water and to improve the degree of cleanliness in the machine.
In the above technical solution, the method includes: the gas inlet is arranged on the shell, and gas flowing into the shell through the gas inlet flows to the combustor; and the air inlets are arranged on the shell.
In this technical scheme, the gas air inlet sets up on the casing, and inside the gas can enter into the casing by the gas air inlet, then flow to the combustor, and the gas is burnt in combustor department to can promote the temperature of the fluid in the water service pipeline through the combustor.
Further, the gas inlet can be provided with a plurality of gas inlets, so that more gas can enter the shell at the same time. Of course, the burner may be provided with a plurality of inlet lines, each inlet line communicating with a corresponding gas inlet, so that more gas may flow towards the burner at the same time.
Through seting up air inlet on the casing to make the air can enter into the casing through air inlet, through the drive of fan, the air can constantly flow to the combustor as combustion-supporting gas.
Further, the air inlets are provided with a plurality of air inlets, so that more air can enter the shell simultaneously, and more combustion-supporting gas flows to the burner simultaneously.
Further, the fan is arranged at one end, far away from the smoke outlet pipe, of the combustor, so that fuel gas and air can be fully mixed before combustion. Because the fan and the smoke outlet pipe are arranged on two sides of the combustor, the air outlet of the fan can blow most of smoke in the shell to be discharged from the smoke outlet pipe quickly and timely, and the shell is effectively cooled.
In the above technical solution, the method includes: the water inlet and the water outlet are arranged on the shell, one end of the water pipeline is connected with the water inlet, and the other end of the water pipeline is connected with the water outlet.
In the technical scheme, the water inlet and the water outlet are both arranged on the shell, and two ends of the water pipeline are respectively connected with the water inlet and the water outlet. After entering the water pipeline from the water inlet, the fluid firstly flows through a part of the water pipeline coiled on the outer side of the smoke outlet pipe, is preheated by the smoke outlet pipe, then flows to a part of the water pipeline passing through the heat exchanger, is heated by the burner and finally is discharged from the water outlet for users to use.
In addition, the embodiment of the water heating apparatus provided by the invention has all the beneficial effects of the embodiments of the first aspect and the second aspect because the heat exchange assembly in any one of the embodiments is provided, and details are not repeated herein.

Generally speaking, the fluid in the water pipeline 3 coiled outside the smoke outlet pipe 21 is tap water directly flowing in through the water inlet pipe, and the temperature of the tap water is normal temperature, so the temperature of the fluid is lower than the temperature of the smoke, and through heat transfer, the temperature of the fluid is increased, and the temperature of the smoke in the smoke outlet pipe 21 is also correspondingly reduced. That is, the water pipe 3 is not in direct contact with the flue gas by means of water-gas heat exchange, the flue gas in the smoke outlet pipe 21 is used to preheat the fluid in the water pipe 3, and the fluid in the water pipe 3 coiled outside the smoke outlet pipe 21 also cools the flue gas with higher temperature.

Further, a gap is formed between the inner wall of the outer tube 82 and the outer wall of the inner tube 81, and the inner tube 81 is communicated with the smoke outlet tube 21. Therefore, the smoke can enter the inner pipe 81 from the smoke outlet pipe 21 and then be discharged from the inner pipe 81.
In addition, the gap between the outer tube 82 and the inner tube 81 allows gas, i.e., air, to enter the inside of the housing 1 through the gap between the outer tube 82 and the inner tube 81. Through setting up thimble assembly 8, the exhaust end sets up with one side with the inlet end, is applicable to the less condition of whole volume, reasonable utilization the space.
Furthermore, since the inner tube 81 is communicated with the smoke outlet tube 21, the outer tube 82 is sleeved outside the inner tube 81, and the outer tube 82 exposed outside the field of view does not directly contact with the smoke outlet tube 21, the temperature of the outer tube 82 is lower than the temperature of the inner tube 81 and the smoke outlet tube 21. And because air can continuously enter the inside of the housing 1 through the gap, the gas can also take away a part of heat of the smoke in the smoke outlet pipe 21 to a certain extent, that is, the temperature of the smoke in the smoke outlet pipe 21 is reduced.
Furthermore, because a part of the water pipeline 3 is coiled outside the smoke outlet pipe 21, most of the heat in the smoke outlet pipe is taken away by the fluid coiled in the water pipeline 3 of the smoke outlet pipe 21, and a small part of the heat is taken into the housing 1 through the gas entering through the gap between the outer pipe 82 and the inner pipe 81, but the temperature in the housing 1 is not very high, compared with the mode that only the sleeve pipe assembly 8 is arranged and the water pipeline 3 is not coiled at the smoke outlet pipe 21, the temperature of the air in the housing 1 can be effectively reduced, and the service life of electric devices in the housing 1 can be prolonged.

Furthermore, the water pipe 3 can be wound on the smoke outlet pipe 21, then the burner 4 heats the fluid in the water pipe 3, and finally the fluid flows out from the discharge end of the water pipe 3 for the user to use. Since the flue gas released by the combustion of the burner 4 will take away a part of the heat, the temperature of the flue gas discharged from the smoke outlet pipe 21 will be high, generally speaking, the fluid in the water pipeline 3 coiled outside the smoke outlet pipe 21 is tap water directly flowing in through the water inlet pipe, and the temperature of the fluid should be normal temperature, so the temperature of the fluid is lower than the temperature of the flue gas, and through heat transfer, the temperature of the fluid will be increased, and the temperature of the flue gas in the smoke outlet pipe 21 will be correspondingly decreased. That is, the water pipe 3 is not in direct contact with the flue gas by means of water-gas heat exchange, the flue gas in the smoke outlet pipe 21 is used to preheat the fluid in the water pipe 3, and the fluid in the water pipe 3 coiled outside the smoke outlet pipe 21 also cools the flue gas with higher temperature. The number of winding turns of the water pipeline 3 outside the smoke outlet pipe 21 is increased, the temperature of smoke exhausted from the smoke outlet pipe 21 can be effectively reduced, and the temperature of the smoke outlet pipe 21 can be controlled within a safe range, so that the possibility that objects around the smoke outlet pipe 21 are deformed by high temperature due to overhigh temperature of the smoke outlet pipe 21, even fire disasters are caused can be reduced, and the safety of the installation environment is improved.
Furthermore, as the fluid in the water pipeline 3 is preheated by the flue gas of the smoke outlet pipe 21, the fluid is heated by the burner 4 after the temperature is increased to a certain degree, and the waste heat of the flue gas is fully utilized, the heat exchange efficiency of the whole machine is improved.
Further, the fluid first flows through the partial water passage 3 wound around the outside of the smoke outlet pipe 21, and then is discharged through the partial water passage 3 passing through the heat exchanger 5.

As shown in fig. 3, an embodiment of the present invention provides a water heating apparatus including a housing 1, a heat exchanger 5, and a heat exchange assembly. The heat exchange assembly is arranged in the shell 1, and the smoke outlet pipe 21 is communicated with the inside and the outside of the shell 1. The heat exchanger 5 is disposed in the casing 1, and is disposed in correspondence with the burner 4. Part of the water passage 3 passes through the heat exchanger 5, and the burner 4 heats the heat exchanger 5 by burning gas, so that the heat exchanger 5 can transfer heat to the fluid in the water passage 3, that is, the burner 4 heats the fluid in the water passage 3 passing through the heat exchanger 5 during operation.
Further, the fluid first flows through the partial water passage 3 wound around the outside of the smoke outlet pipe 21, and then is discharged through the partial water passage 3 passing through the heat exchanger 5. Namely, the fluid is preheated by the smoke of the smoke outlet pipe 21, then is heated by the burner 4, and finally is discharged for the user. The preheated fluid has an increased temperature compared to the previous one, and can reach the temperature preset by the user more quickly by means of the burner 4. Therefore, in the whole process, the heating efficiency of the fluid is improved, the temperature of the smoke in the smoke outlet pipe 21 is reduced, and the safety of the installation environment is improved.
Furthermore, because a part of the water pipeline 3 is coiled outside the smoke outlet pipe 21, most of the heat in the smoke outlet pipe is taken away by the fluid coiled in the water pipeline 3 of the smoke outlet pipe 21, and a small part of the heat is taken into the housing 1 through the gas entering through the gap between the outer pipe 82 and the inner pipe 81, but the temperature in the housing 1 is not very high, compared with the mode that only the sleeve pipe assembly 8 is arranged and the water pipeline 3 is not coiled at the smoke outlet pipe 21, the temperature of the air in the housing 1 can be effectively reduced, and the service life of electric devices in the housing 1 can be prolonged.
Further, since the fluid is preheated by the flue gas passing through the flue gas outlet pipe 21 before entering the heat exchanger 5, the temperature of the fluid entering the heat exchanger 5 is increased compared to the previous temperature, and the temperature of the heat exchanger 5 is also increased by heat transfer, so that the temperature difference between the wall surface of the heat exchanger 5 and the flue gas with higher temperature is reduced. The flue gas generated by combustion contains partial water vapor, particles and other substances, so that the temperature difference between the wall surface of the heat exchanger 5 and the flue gas is reduced, and the flue gas generated by combustion is favorably kept at a temperature higher than the dew point temperature when contacting the wall surface of the heat exchanger 5. The dew point temperature is the temperature at which the water vapor and the water reach an equilibrium state, and when the actual temperature is higher than the dew point temperature, the air is not saturated, so that the generation of condensed water is limited. That is, if the flue gas generated by combustion is kept at a temperature higher than the dew point temperature even after contacting the wall surface of the heat exchanger 5 having a relatively low temperature, the water vapor in the flue gas does not become condensed water, and harmful particles are not retained in the casing 1 by the condensed water.

That is, the water pipe does not directly contact with the flue gas by means of water-gas heat exchange, the flue gas in the smoke outlet pipe 21 is used to preheat the fluid in the water pipe 3, and the fluid in the water pipe 3 coiled outside the smoke outlet pipe 21 also cools the flue gas with higher temperature. The number of winding turns of the water pipeline 3 outside the smoke outlet pipe 21 is increased, the temperature of smoke exhausted from the smoke outlet pipe 21 can be effectively reduced, and the temperature of the smoke outlet pipe 21 can be controlled within a safe range, so that the possibility that objects around the smoke outlet pipe 21 are deformed by high temperature due to overhigh temperature of the smoke outlet pipe 21, even fire disasters are caused can be reduced, and the safety of the installation environment is improved.
Further, because the fluid in the water pipeline 3 is preheated by the flue gas of the smoke outlet pipe 21, after a certain temperature is increased, the temperature is increased by the burner 4, and the waste heat of the flue gas is fully utilized, the heating efficiency of the fluid is improved in the whole process, and the heat exchange efficiency of the whole water heating device is improved.
