The secondary heat exchanger has the advantages of being capable of using the temperature of exhaust gas to heat the water in the main heat exchanger in the fuel gas heating water heater, improving the water yield of hot water, and further improving the heat efficiency of the gas heating water heater, and being compact in structure.
Description
Technical field
The utility model relates to a kind of secondary heat exchanger of gas-heating water heater.
Background technology
Existing gas-heating water heater comprises housing, be located at burner in lower housing portion, be located at the heat exchanger in housing middle part and be located at the exhaust blower in housing top.When work, the heating of burner heat exchanger, exhaust blower is discharged waste gas; The temperature of the waste gas that exhaust blower is discharged is higher, and when air draft, the temperature of waste gas has been wasted, and also affects indoor temperature.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and a kind of temperature that can utilize waste gas is provided, and further improves the secondary heat exchanger of the gas-heating water heater of the thermal efficiency of gas-heating water heater.
In order to achieve the above object, the utility model is achieved in that it is a kind of secondary heat exchanger of gas-heating water heater, is characterized in that comprising:
Shell body is provided with air inlet on described shell body, and described air inlet is communicated with the air outlet of the exhaust blower of gas-heating water heater, is provided with gas outlet at the top of shell body, and described gas outlet is communicated with the exhaust outlet of gas-heating water heater;
Secondary water tank, described secondary water tank is located in shell body, and the outer wall of secondary water tank and the inwall of shell body are gapped; Top at secondary water tank is provided with delivery port, and described delivery port is communicated with the water inlet of the main heat exchanger of gas-heating water heater by tube connector, is provided with water inlet in the bottom of secondary water tank, and described water inlet is communicated with heating water return by pipeline; And
Heat-exchange device, described heat-exchange device is located in secondary water tank, and the air intake of heat-exchange device is communicated with gap, and the gas outlet of heat-exchange device is communicated with the exhaust outlet of gas-heating water heater.
Further be improved to, also comprise two above ventilation shafts, described ventilation shaft is also fixing through the inner chamber of secondary water tank, and the air intake of ventilation shaft is communicated with gap, and the gas outlet of ventilation shaft is communicated with the gas outlet of shell body.
The utility model advantage is compared with prior art: can utilize the temperature of waste gas to heat the water of the main heat exchanger that enters gas-heating water heater, improve hot water effluent's amount, further improve the thermal efficiency of gas-heating water heater, compact conformation.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.It should be noted that at this, be used for helping to understand the utility model for the explanation of these embodiments, but do not form restriction of the present utility model.In addition,, in each embodiment of described the utility model, involved technical characterictic just can interosculate as long as do not form each other conflict.
In the utility model is described, orientation or the position relationship of the instruction such as term " top " and " bottom " are based on orientation shown in the drawings or position relationship, it is only the utility model instead of require the utility model with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model for convenience of description.
As shown in Fig. 1 to 5, it is a kind of secondary heat exchanger of gas-heating water heater, comprising:
Heat-exchange device, described heat-exchange device is located in secondary water tank 4, and the air intake of heat-exchange device is communicated with gap 24, and the gas outlet of heat-exchange device is communicated with the exhaust outlet of gas-heating water heater 1, forms like this smoke discharging passage.
When work, the waste gas that exhaust blower 9 is sent enters into gap 24 by the air inlet 3 of shell body 2, this waste gas is discharged from gas outlet by heat-exchange device again, now the waste gas in gap 24 and the waste gas in heat-exchange device enter preheating to the water in secondary water tank 4, water after preheating enters into again the main heat exchanger 8 of gas-heating water heater, thereby improve hot water effluent's amount, so also just improved efficiency of combustion.
Further improvement of this embodiment is, described heat-exchange device comprises ten ventilation shafts 5, described ventilation shaft 5 is also fixing through the inner chamber of secondary water tank 4, and the air intake vent of ventilation shaft 5 is communicated with gap 24, and the air outlet of ventilation shaft 5 is communicated with the gas outlet 21 of shell body 2.Also can select according to actual conditions the quantity of ventilation shaft, but need be more than two.
When work, when waste gas passes through every ventilation shaft 5, can carry out homogeneous heating to the water in secondary water tank 4.
Below by reference to the accompanying drawings embodiment of the present utility model is made to detailed description, but the utility model is not limited to described embodiment.For the ordinary skill in the art, in the situation that not departing from principle of the present utility model and aim, these embodiments being carried out to multiple variation, amendment, replacement and distortion still falls within protection domain of the present utility model.
