Abstract
The utility model relates to a domestic gas heater heat exchanger, its characterized in that: including upper and lower both ends open-ended combustion chamber box (1), be equipped with heat insulating board (2) in combustion chamber box (1) inboard, be equipped with heat transfer fin (3) and straight tube (4) above combustion chamber box (1), straight tube (4) one end is connected with inlet tube (5), the other end is connected with outlet pipe (6), this domestic gas water heater heat exchanger reduces copper product use amount 30%, reduce manufacturing cost by a wide margin, show the increasing the thermal efficiency, reduce greatly and ward off the tin area, greatly reduced the pollution to the environment.
Description
[technical field]
The utility model relates to a kind of heat exchanger, particularly a kind of domestic gas-fired water heater heat exchanger.
[background technology]
The heat exchanger of existing domestic gas-fired water heater generally adopts scale copper to make the combustion chamber, water inlet pipe is arranged at the outside, combustion chamber, water inlet pipe is that a kind of coiling mode designs, there are the following problems for this design: owing to combustion chamber employing copper material making and at its outside coiling copper pipe, the copper material consumption is relatively many, causes manufacturing cost relatively high; Because the combustion chamber is without thermal insulation layer, heat loss is large, causes the thermal efficiency lower; Because common copper material antioxygenic property is poor, heat-exchanger surface need be warded off tin and process, and can cause environmental pollution and ward off process of tin, is unfavorable for environmental protection.
[utility model content]
The utility model provides a kind of domestic gas-fired water heater heat exchanger, reduce copper material use amount 30%, significantly reduce manufacturing cost, significantly improve the thermal efficiency of domestic gas-fired water heater heat exchanger, decrease domestic gas-fired water heater heat exchanger is warded off the tin area, greatly reduces the pollution to environment.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of domestic gas-fired water heater heat exchanger, comprise both ends open up and down the combustion chamber casing, be provided with thermal insulation board at the combustion chamber box inside, above the casing of combustion chamber, be provided with heat exchange fin and straight tube, straight tube one end is connected with water inlet pipe, and the other end is connected with outlet pipe.
The combustion chamber casing adopts cold-reduced sheet to make as mentioned above.
Thermal insulation board adopts ceramic fibre to make as mentioned above.
Heat exchange fin adopts scale copper to make as mentioned above.
Straight tube, water inlet pipe, outlet pipe adopt copper pipe to make as mentioned above.
The beneficial effects of the utility model are:
⑴, the expensive copper material use amount 30% of minimizing significantly reduce domestic gas-fired water heater heat exchanger manufacturing cost;
⑵, significantly improve the thermal efficiency of domestic gas-fired water heater heat exchanger;
⑶, decrease domestic gas-fired water heater heat exchanger are warded off the tin area, greatly reduce the pollution to environment.

Fig. 1 is the utility model front section view;
Fig. 2 is the utility model side sectional view;
[specific embodiment]
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of domestic gas-fired water heater heat exchanger, comprise both ends open up and down combustion chamber casing 1, be provided with thermal insulation board 2 in combustion chamber casing 1 inboard, above combustion chamber casing 1, be provided with heat exchange fin 3 and straight tube 4, straight tube 4 one ends are connected with water inlet pipe 5, and the other end is connected with outlet pipe 6.
In the utility model; described combustion chamber casing 1 adopts cold-reduced sheet to make; make the coil pipe that combustion chamber cancellation conventional heat exchanger generally adopts owing to adopting common cold bundle book steel plate to add the high temperature resistant heat insulation plate; therefore can reduce expensive copper material use amount 30%; significantly reduce manufacturing cost; but the decrease heat exchanger is warded off the tin area in addition, plays the effect that promotes environmental protection.
In the utility model, described thermal insulation board 2 adopts ceramic fibre to make, since the combustion chamber installed inside have good effect of heat insulation and a thermostable heat insulation plate 2, so that the ratio that the heat energy that fuel gas buring produces loses by the combustion chamber obviously reduces, therefore can significantly improve the thermal efficiency of water heater.
In the utility model, described heat exchange fin 3 is made by scale copper, this organizes the heat energy that heat exchange fin 3 absorbs in high-temperature flue gas, and the heat energy that absorbs is conducted the cold water that flows to from water inlet pipe 5 by the straight tube 4 that is placed in one, and cold water flows out from outlet pipe 6 after absorbing this heat energy intensification.
In the utility model, described straight tube 4, water inlet pipe 5, outlet pipe 6 adopt copper pipe to make, and can carry out fast the heat conduction, absorb the heat that comes out in the combustion chamber, heat for the cold water that flows through pipeline.
With heat exchange fin 3, water inlet pipe 5, outlet pipe 6 and the straight tube 4 that plays anastomosis by being press-fitted and soldering processes are made and formed heat exchange section, this sub-assembly is cooperated with combustion chamber casing 1 top square groove and the soldering connection, again at combustion chamber casing 1 inboard ceramic embedded fiberboard.
Claims (5)
