Description
Technical field
Field of water heaters is the utility model is related to, more particularly, to the combustion gas heat that a kind of thermal efficiency is high, combustion gas utilization rate is high
Hydrophone.
Background technology
In the prior art, gas heater uses gas heating, the high-temperature gas after heating in heating process
Into the pipeline being coiled on the outside of water tank, using the mode of heat transfer to the cool water heating inside water tank, but such heat transfer
Inefficient, the utilization rate of pipeline heat transfer surface area is low, has slatterned calorific value, while gas heater is all to use common stove
Mouth jet combustion, common converter nose jet velocity is slow, and extraneous air is not sufficiently mixed with combustion gas, and incomplete combustion can lose
Fall some heats, also result in and produce more pernicious gases.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of heat transference efficiency height, combustion gas utilization rate
High gas heater.
The technical solution adopted in the utility model is：A kind of high gas heater of thermal efficiency, including：
Housing, water inlet, delivery port, exhaust opening and gas port are provided with the housing, and be all arranged on enclosure interior
's
Water tank, water tank one end connection water inlet, other end connection delivery port；
Burner, the burner are connected with gas port for providing heat to water tank；And
Calorific value transmission pipe, the calorific value transmit pipe and are arranged on inside water tank, and the calorific value transmits pipe one end connection burner, another
One end connects exhaust opening.
Calorific value transmits pipe and is arranged to helical coiled tube.
Burner includes：
Combustion chamber, the combustion chamber are arranged on enclosure interior, and combustion chamber is shaped to up-narrow and down-wide cavity volume, the burning
Ceiling portion offers a through hole being connected with calorific value transmission pipe；And
Burner；The burner is arranged on combustion chamber and is connected with gas port, be provided with the burner for
The high pressure nozzle of outer jet high speed fuel gas.
High speed nozzle lateral wall is provided with what is mixed for making extraneous air into high speed nozzle inside and with fuel gas
Air admission hole.
The beneficial effects of the utility model：The design provides a kind of thermal efficiency high gas heater, by the way that calorific value is passed
Pass pipe to be arranged on inside water tank, improve the utilization rate that calorific value transmits pipe heat transfer surface area, take full advantage of heat, make hot water
It is easily boiled.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation of the high gas heater of thermal efficiency of the utility model.
Embodiment
As shown in figure 1, the gas heater that a kind of thermal efficiency is high, including housing 1, be provided with the housing 1 water inlet 2,
Delivery port 3, exhaust opening 4 and gas port 5, and the water tank 6, burner 7 and the calorific value that are all arranged on inside housing 1 transmit pipe 8,
The one end of water tank 6 connection water inlet 2, other end connection delivery port 3, burner 7 are connected with gas port 5 for being carried to water tank 6
Heating load, calorific value transmit pipe 8 and are arranged on inside water tank 6, and the calorific value transmits the one end of pipe 8 connection burner 7, other end connection row
Mouth 4, burner 7 burn caused high-temperature flue gas into calorific value transmission pipe 8, and high-temperature flue gas is the water heating in water tank 6, hot
Value can be fully only absorbed by the water.Until calorific value transmits the flue-gas temperature of discharge in pipe 8 close to water temperature, so degrade again in smoke exhaust pipe
Carbon monoxide content, and all calorific values when taking full advantage of fuel gas buring, the existing tankless water heater efficiency of Energy Efficiency Ratio
Improve 30%.
Preferably, calorific value transmits pipe 8 and is arranged to helical coiled tube, can effectively increase heat transfer surface area, all
Calorific value utilize to maximum, the design can reduce the volume of water tank 6, and can accomplish very thin, and the thickness of water tank 6 may be configured as 45-
50mm。
Further, burner 7 includes combustion chamber 71 and burner 72, and combustion chamber 71 is arranged on inside housing 1, burning
Room 71 is shaped to up-narrow and down-wide cavity volume, and the top of combustion chamber 71 offers a through hole being connected with calorific value transmission pipe 8
711, burner 72 is arranged on the inside of combustion chamber 71 and is connected with gas port 5, is provided with the burner 72 for being sprayed to outside
Penetrate the high pressure nozzle 73 of high speed fuel gas, combustion chamber 71 can effectively pilot burner 72 burn caused by high-temperature flue gas along
The inwall of combustion chamber 71, which is concentrated, enters through hole 711, reduces high-temperature flue gas in the residence time of combustion chamber 71 so as to reduce calorific value
Loss.High pressure nozzle 73 can be in the suitable portion on the gas channel of high pressure nozzle 73 using higher fuel gas spouting velocity
Position forms lower pressure to be gone more air inspirations and be sufficiently mixed generation vigorous reaction with fuel gas, makes burning more
Add fully, temperature is higher.
Preferably, the lateral wall of high speed nozzle 73 be provided with for make extraneous air enter the inside of high speed nozzle 73 and with it is flammable
The air admission hole of gas mixing.
Preferred embodiments of the present utility model are the foregoing is only, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the technical scheme of the utility model purpose belong to the scope of protection of the utility model it
It is interior.
