Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
The present invention has designed a kind of novel heat exchanging fin, and this heat exchanging fin can adopt non-ferrous metal extrusion modling, and this heat exchanging fin provides water pipe and air flue, novel structure.
On heat exchanging fin, set up fin, can improve heat exchange area, improve heat exchanger effectiveness.
The present invention has designed a kind of novel heat exchanger, i.e. multitube matrix form heat exchanger utilizes the multitube distributing principle of being heated, and realizes Fast Heating, stable heating.Enter singly to go out heat exchange form with traditional Large Diameter Pipeline list and compare, heat exchanger of the present invention has the advantages such as heating surface area is large, firing rate is fast, leaving water temperature is stable.The present invention adopts the heat exchanging fin of the stacked setting of multi-disc, and heat-exchange tube series connection is arranged, and has extended the path of hot gas in heat exchanger, extended heat exchanger time, meanwhile, water at least needs through every one deck heat exchanging fin once, be repeated heating, firing rate is faster.
The invention provides a kind of concrete basic mode that heat exchanging fin is connected, by connection water channel, connect levels heat-exchange tube, the connection water channel of heat exchanger both sides is arranged alternately, and makes water necessary through every one deck heat-exchange tube in heat exchanger.Certainly, can also improve this, for example, by each root heat-exchange tube series connection, make water necessary through each root heat-exchange tube in heat exchanger.By that analogy.The advantage of heat exchanging fin series connection is, 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.Here said lower one deck is said according to water (flow) direction, is not the position relation of heat exchanging fin.Internal end cover fits tightly on the notch of outer end cap, is that connection water channel forms a closely knit water channel, and insert after connection water channel through heat-exchange tube installing hole the termination of heat-exchange tube, and water can only flow into or flow out from heat-exchange tube.
Heat-exchange tube installing hole is longitudinally crisscross arranged, can makes the through hole on heat exchanging fin staggered, namely flue is extended, reduce the through-rate of hot gas simultaneously, totally increased heat exchanger time.
A kind of gas heater provided by the invention, heat exchanger is arranged in condenser jacket, makes in the space of heat exchanging fin in a four sides sealing, and hot gas only can prevent that it from spreading to surrounding from below to rising, has improved the utilization rate of hot gas.Hot gas is in the process rising, and continuous and heat exchanging fin carries out heat exchange.
Condenser jacket hollow is arranged, be about to condenser jacket and be set to water leg, allow condenser jacket absorb the heat of both sides, heat exchanger front and back.First water enter condenser, after tentatively being heated, enters heat exchanger again, and heat is fully utilized, and has reduced heat loss.
Adopt independently combustion chamber, be conducive to guarantee combustion gas normal combustion, and limited heat and spread to surrounding.Also for controlling fuel gas buring, provide condition simultaneously.
On air inlet sleeve pipe, gas mixing valve is installed, can be made combustion gas mix by preset ratio with oxygen, be conducive to improve the combustion rate of combustion gas.
Air inlet at combustion chamber lower cover lower cover is installed blower fan, and blower fan enters ，Wei combustion chamber, combustion chamber by air by air inlet sufficient oxygen is provided, and 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, guarantees that hot gas, smoothly through over-heat-exchanger, improves heat exchange area, thereby guarantees 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 of adjusting between flame and heat exchanger, so that Btu utilization is more abundant, can also save combustion gas simultaneously.
Utilize the generating power by water current in water heater, each power consumption parts that can be in water heater provide electric energy.For example, a 12V, 2A differential pressure power generation machine are installed, can be met user demand.Can also use battery that rich power storage is standby simultaneously.For improving efficiency of energy utilization, can also utilize the generating of semiconductor temperature differential generating sheet, for example, the one side of semiconductor temperature difference being sent out to spot film is sticked at combustion chamber lower cover sidewall, utilizes the temperature difference generating of combustion chamber lower cover and outside air.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 to realize the object of self power generation it.
Water is heated in water heater, from hot-water line, flows out.Conventionally, last use after water heater, the water in hot-water line is still present in this water pipe, probably lowers the temperature when using water heater next time.Emptier is installed on hot-water line, can utilizes air that water in hot-water line is discharged, while using water heater next time, can plug and play, reduced the waste of water resource.
The design of fire dish and mixed gas head, can guarantee that combustion gas fully burns, and burning is more stable.Meanwhile, can also, at the mixed catalyst layer that is coated with in a fit of anger, improve fuel gas buring efficiency.
Traditional burner combustion temperature is 1050 ° of left and right, and the present invention can bring up to burner combustion temperature 1430 ° of left and right, and result of use is very obvious.
