Abstract

The utility model relates to a water heating stove, which is composed of a burner assemblage, a tubular heat exchanger, etc., wherein, the lower part of the tubular heat exchanger is a burning chamber whose wall is a water sleeve interlayer. The lower and the upper parts of the tubular heat exchanger are respectively provided with a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are used for making up a heating system with a radiator, etc. A thin metal tube which is long enough and circle-shaped is arranged in the water chamber of the tubular heat exchanger, and the thin metal tube can be used for transferring water. When water passes through the thin metal tube, not only the water can not be infected with the water in the water chamber of the tubular heat exchanger, but also the water is heated and can be used for hot water shower. Thus two strands of flowing water with different functions are formed in the heat exchanger of the same hot water stove. Thus the use functions of the hot water stove is added.

Description

Two current shell and tube water heaters

The utility model design relates to the technological improvement to a kind of water heater that is combined into by tubular heat exchanger and burner etc., to increase the function of use of water heater.

A kind of water heater system that has emerged is by burner and be positioned at tubular heat exchanger directly over the burner etc. and form.Wherein the bottom of tubular heat exchanger is to be the combustion chamber of wall with the water jacket samdwich, and the bottom of heat exchanger and top are shaped on water inlet pipe and outlet pipe respectively, in order to be connected with radiator, forms the gerotor type winter heating system that is applicable to general family.Its defective is: 1, the hot water of heating system has the rust dirt in the radiator, and is not suitable for Water-heating shower; 2, the hot water in the same normal pressure system should heating shower again, and current should not be controlled.

The purpose of the utility model design is the function of use that will increase this water heater, makes it not only be applicable to heating, while but also be applicable to Water-heating shower.

The improvement measure of the utility model design, be in the water cavity of former tubular heat exchanger, to increase a sufficiently long metal thin tube that can water delivery, when current during through this metal thin tube, both with the heat exchanger water cavity in hot water do not dye mutually mutually, be applicable to shower again by the hot water in heat exchanger water cavity heating; Because the common metal tubule has higher bearing capacity, thereby is convenient to the control of current.

This is suitable for novel specification drawings attached 3 width of cloth, and Fig. 1 is the structural representation (double as specification digest accompanying drawing) of the utility model design embodiment, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the B-B profile of Fig. 1.Represented parts and the position of sequence number is respectively among the figure: 1. burner assembly, 2. the combustion chamber of heat exchanger bottom, 3. the inner layer wall of combustion chamber, 4. the outer wall of combustion chamber, 5. lower perforated plate, 6. upper perforated plate, 7. tube bank, 8. outer cover of heat exchanger, 9. water inlet pipe, 10. outlet pipe, 11. metal thin tube, 12. the stationary pipes of metal thin tube 11, the stationary pipes of 13. metal thin tubes 11, the protective cover that 14. heat exchangers are outer, 15. the enclosure of heat exchanger, 16. the upper cover plate of protective cover 14, the inner rib plate of 17. tube banks 7, the glory hole of 18. combustion chamber water jacket samdwich walls.

As seen from Figure 1, water heater of the present utility model system is by burner assembly 1 be positioned at tubular heat exchanger directly over the burner assembly 1 etc. and form.Wherein the bottom of tubular heat exchanger is to be the combustion chamber 2 of wall with the water jacket samdwich, and combustion chamber 2 is to be made of inner layer wall 3 and outer wall 4; The top of combustion chamber 2 is lower perforated plates 5, by equal number on upper perforated plate 6 and the lower perforated plate 5 and the upper and lower port of all tube banks 7 in the plate face through hole stationary heat exchangers one to one; The lower end of outer cover of heat exchanger 8 is connected with the upper end of outer wall of combustion chamber 4, and the upper port of outer cover of heat exchanger 8 is connected with the outer rim of upper perforated plate 6; Respectively be shaped on water inlet pipe 9 (being convenient to from a left side or the right water inlet) about on the outside wall surface of outer wall of combustion chamber 4, respectively be shaped on outlet pipe 10 (being convenient to from a left side or the right water outlet) about on the outside wall surface of the upper end of outer cover of heat exchanger 8, in order to form the gerotor type heating system with radiator etc.

Be also shown in by Fig. 1, the water cavity of heat exchanger be built-in with a long enough, can water delivery metal thin tube 11; Metal thin tube 11 in the heat exchanger water cavity around tube bank 7 shapes in the shape of a spiral.Upper perforated plate 6 also is shaped on two eyelets and is shaped on two short tubes 12 and 13 on the upper face at this eyelet place, in order to two terminations of fixing metal tubule 11; The advantage of this design is: when all tube bank upper port of 7 are inserted the plate face through hole of upper perforated plate 6, two terminations of metal thin tube 11 directly can be inserted in the endoporus of short tube 12 and short tube 13, be fixed, and simplify manufacturing process.

Fig. 2 is the A-A profile of Fig. 1, and Fig. 2 further specifies the version of metal thin tube 11 in water cavity in conjunction with Fig. 1.Fig. 2 also cuts open and has shown that being shaped on some and tube wall on tube bank 7 internal face is the longitudinal fin 17 of one, in order to the internal face that enlarges tube bank 7 and the effective heat exchange area of hot flame cigarette.

Fig. 3 is the B-B profile of Fig. 1, and further specifying combustion chamber 2 is the spaces that water jacket samdwich surrounded that are made of inner layer wall 3 and outer wall 4; On the water jacket samdwich wall, also be shaped on glory hole 18.

The manufactured materials of the heat exchanger of the utility model water heater as whole employing aluminium alloys, then has the following advantages: can adopt aluminium alloy extruded technology, one-shot forming has the tube bank 7 of inner rib plate, enlarges heat exchange area, and heat exchange property is good; Technology with aluminium sheet stamping combustion chamber ectonexine wall and last lower perforated plate is simple; Aluminium alloy tubule 11 after the annealing is convenient to around moulding; Aluminium alloy has good corrosion resisting property and good welding performance etc.

The operation principle of the utility model water heater is: the flame of being made by burner assembly 1 occurs in 2 spaces, combustion chamber, the hot flame cigarette is along the inwall rising of tube bank 7, the water in the heating heat exchanger water cavity, and burnt exhaust gas overflows, arranges to outdoor via flue from enclosure 15; Meanwhile, the cold backwater of heating system is gone into water cavity from water inlet pipe 9, after being heated, flows out from outlet pipe 10, flows to radiator.In above-mentioned heating hot water periodic duty, another plume water flows into metal thin tubes 11 from fixing short tube 12, through around process of flowing, after the heating of the hot water in the heat exchanger water cavity, from fixedly short tube 13 outflows, flows to shower cabinet.Like this, in the tubular heat exchanger of same water heater, promptly form two plume water that heating and shower are not dyed mutually mutually, thereby increased the function of use of water heater.
