Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
The present invention have devised a kind of novel heat exchanging fin, and this heat exchanging fin can adopt non-ferrous metal extruded, and this heat exchanging fin provides water pipe and air flue, novel structure.
Heat exchanging fin sets up fin, can heat exchange area be improved, improve heat exchanger effectiveness.
The present invention devises a kind of novel heat exchanger, i.e. multitube matrix form heat exchanger, utilizes multitube distributing to be heated principle, realizes Fast Heating, stable heating.Compared with entering singly to go out heat exchange form with traditional Large Diameter Pipeline list, heat exchanger of the present invention has the advantages such as heating surface area is large, firing rate fast, stable in outlet water temperature.The present invention adopts the heat exchanging fin of the stacked setting of multi-disc, is arranged in series by heat-exchange tube, extends the path of hot gas in heat exchanger, namely extend heat exchanger time, meanwhile, water at least needs through every one deck heat exchanging fin once, by Repeat-heating, firing rate is faster.
The invention provides a kind of basal profile of being connected by heat exchanging fin specifically, namely connect levels heat-exchange tube by connection water channel, the connection water channel of heat exchanger both sides is arranged alternately, and makes water in heat exchanger, have to pass through every one deck heat-exchange tube.Certainly, can also improve this, such as, each root heat-exchange tube be connected, makes water in heat exchanger, have to pass through each root heat-exchange tube.By that analogy.The advantage that heat exchanging fin is connected be, water carried out mixing with this after entering every one deck heat exchanging fin, flowed into lower one deck heat exchanging fin after mixing again.Lower one deck mentioned here is said according to water (flow) direction, is not the position relation of heat exchanging fin.Inner end cap fits tightly on the notch of outer end cap, is that connection water channel forms a closely knit water channel, and after connection water channel is inserted through heat-exchange tube installing hole in the termination of heat-exchange tube, water can only flow into from heat-exchange tube or flow out.
Heat-exchange tube installing hole is longitudinally crisscross arranged, the through hole on heat exchanging fin can be made to interlock, namely flue is extended, reduce the through-rate of hot gas simultaneously, totally add heat exchanger time.
A kind of gas heater provided by the invention, heat exchanger is arranged in condenser jacket, and heat exchanging fin is in the space of a four sides sealing, and hot gas only can, from below to rising, prevent it from spreading to surrounding, improves the utilization rate of hot gas.Hot gas is in the process risen, and continuous and heat exchanging fin carries out heat exchange.
Condenser jacket hollow is arranged, is set to water leg by condenser jacket, allow condenser jacket absorb the heat of both sides before and after heat exchanger.First water enter condenser, and enter heat exchanger again after tentatively being heated, heat is fully utilized, and reduces heat loss.
Adopt independently combustion chamber, be conducive to ensureing combustion gas normal combustion, and limit heat and spread to surrounding.Also provide condition for controlling fuel gas buring simultaneously.
Gas mixing valve installed by air inlet sleeve pipe, combustion gas can be made to mix by preset ratio with oxygen, be conducive to the combustion rate improving combustion gas.
Install blower fan at the air inlet of combustion chamber lower cover lower cover, air is entered combustion chamber by air inlet by blower fan, for combustion chamber provides sufficient oxygen, makes fuel gas buring abundant.Meanwhile, under the effect of blower fan, form air-flow from bottom to top in water heater, under the effect of air-flow, the hot gas that fuel gas buring produces rises gradually, ensures that hot gas is smoothly through over-heat-exchanger, improves heat exchange area, thus ensures heat exchange effect.
Below fire dish, elevating mechanism is installed, this elevating mechanism is for controlling the position of fire dish in the vertical direction, more particularly control the distance between fire dish and heat exchanger, more direct object is the distance between adjustment flame and heat exchanger, to make Btu utilization more abundant, combustion gas can also be saved simultaneously.
Utilize the generating power by water current in water heater, each power-consuming component that can be in water heater provides electric energy.Such as, 12V, 2A differential pressure power generation machine is installed, can user demand be met.Battery can also be used for subsequent use for the power storage of affluence simultaneously.For improving efficiency of energy utilization, semiconductor temperature differential generating sheet can also be utilized to generate electricity, and such as, one side semiconductor temperature difference being sent out spot film is sticked at combustion chamber lower cover sidewall, utilizes the temperature difference of combustion chamber lower cover and outside air to generate electricity.Differential pressure power generation machine and semiconductor temperature differential generating sheet all belong to ripe technology, and the present invention is applied in water heater it to realize the object of self power generation.
Water is heated in water heater, flows out from hot-water line.Usually, after last use water heater, the water in hot-water line is still present in this water pipe, probably lowers the temperature to using during water heater next time.Emptier installed by hot-water line, air can be utilized to be discharged by the water in hot-water line, when using water heater next time, can plug and play, decrease the waste of water resource.
The design of fire dish and mixed gas head, can ensure combustion gas Thorough combustion, and burning is more stable.Meanwhile, catalyst layer can also be coated with in a fit of anger mixed, improve fuel gas buring efficiency.
Traditional burner combustion temperature is about 1050 °, and burner combustion temperature can be brought up to about 1430 ° by the present invention, and result of use is obviously.
