Abstract
The utility model relates to a sensible heat exchanger of a fuel gas water heater, comprising a shell, a water pipe, an elbow joint, fins and a straight pipe. The shell is provided with a main plane and a transition cambered surface; the fins are fixed on the straight pipe which is communicated with the water pipe through the elbow joint; and the water pipe consists of a straight-line segment pipeand a transition segment pipe and is entwined on the outer wall of the shell. The sensible heat exchanger is mainly technically characterized in that the straight-line segment pipe is a D-shaped pipe, and a plane in the straight-line segment pipe is welded with the main plane of the outer wall in the shell. The utility model has the characteristics of effectively increasing the contact area of the water pipe and the shell, further improving the heat exchanging efficiency, being reliably fixed, and the like.
Description
Technical field:
The utility model relates to a kind of sensible heat exchanger of gas heater.
Background technology:
In the prior art, it is circular pipe that water pipe on the gas heater sensible heat exchanger adopts the cross section mostly, the surface of shell of sensible heat exchanger contacts with water pipe and is the line contact, its contact area is little, cause the heat exchange performance of water pipe and housing to be restricted, and then exist heat exchange efficiency low, and reliability of fixation is subjected to certain defectives such as restriction.For overcoming these defectives, the sensible heat exchanger of gas heater is improved.
Summary of the invention:
Technical problem to be solved in the utility model is the sensible heat exchanger that a kind of gas heater will be provided, and it can increase the contact area of water pipe and housing effectively, and then improves heat exchange efficiency, and fixing reliable.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises housing, water pipe, union elbow, fin, straight tube, housing is provided with main body plane and transition cambered surface, fin is fixed on the straight tube, straight tube is by union elbow and cross current, water pipe is made of straightway pipe and changeover portion pipe, and be coiled on the outer wall of housing, described straightway pipe is " D " type pipe, the main body plane of outer wall welding in plane in the straightway pipe and the housing.
Described changeover portion pipe is " D " type pipe, changeover portion pipe and the welding of transition cambered surface outer wall.
Described changeover portion pipe is a pipe, changeover portion pipe and the welding of transition cambered surface outer wall.
Described " D " type pipe is that the cross section is by one section straight line and one section pipe that camber line connects and composes.
Described " D " type pipe is that the cross section is by two sections straight lines and two sections pipes that camber line connects and composes at interval.
Described straight tube passes fin fin is fixed on the straight tube.
Describedly be welded as soldering.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model employing straightway pipe is " D " type pipe, the main body plane welded structure of outer wall in plane in the straightway pipe and the housing so it can increase the contact area of water pipe and housing effectively, and then improves heat exchange efficiency, and fixing reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
" D " the type pipe that Fig. 2 is connected and composed by one section straight line and one section camber line for the cross section for Fig. 1 cathetus section pipe 4 and the annexation schematic diagram of housing 1.
" D " the type pipe that Fig. 3 is connected and composed by two sections straight lines and two sections camber lines for the cross section at interval for Fig. 1 cathetus section pipe 4 and the annexation schematic diagram of housing 1.
The specific embodiment:
Referring to accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, present embodiment comprises housing 1, water pipe 2, union elbow 3, fin 6, straight tube 7, " D " type pipe that water pipe 2 is made for metal material, straight tube 7 passes fin 6 fin 6 is fixed on the straight tube 7, straight tube 7 is communicated with water pipe 2 by union elbow 3, water pipe 2 is made of straightway pipe 4 and changeover portion pipe 5, and be coiled on the outer wall of housing 1, straightway pipe 4 is " D " type pipe, " D " type tube section can be one section straight line and one section camber line connects to form (as shown in Figure 2), also can be two sections straight lines and two sections camber lines are cross-linked composition (as shown in Figure 3).Plane 10 in the straightway pipe 4 is connected with main body plane 8 solderings of outer wall in the housing 1, changeover portion pipe 5 can be " D " type pipe, also can be pipe, it in the present embodiment " D " type pipe, and changeover portion pipe 5 is connected with the 9 outer wall solderings of transition cambered surface, in the practical operation,, can not weld with transition cambered surface 9 outer walls because changeover portion pipe 5 is shorter yet.
When combustion gas in the gas heater during in the sensible heat exchanger internal combustion, the part heat of burning passes to the water in fin 6, straight tube 7, the straight tube 7 successively, thereby gives the heating of the water in the straight tube 7.Other a part of heat of burning is delivered on the housing 1 of sensible heat exchanger, and the heat in the housing 1 conducts to the water pipe 2 that is in contact with it again, and the heat that water pipe 2 is obtained conducts the water in the feed pipe 2 again, thus the heating of the water in the feed pipe 2.
Because the outer wall plane contact of water pipe 2 cathetus section pipes 4 and housing 1, changeover portion pipe 5 contacts with housing 1 outside wall surface, and the conduction surface of heat transmission increases greatly between housing 1 and the water pipe 2, so can improve heat exchange efficiency effectively.Contact-making surface is a plane, more convenient operation when welding, and weld more firmly.
