Abstract

The utility model relates to a novel energy-saving water tank for gas water heaters, which is put forward by aiming at that the prior water tanks used in the gas water heaters cannot utilize the high-temperature heat value of gas to the utmost extent and cause energy loss. On the basis of connecting the upper end of an existing bucket with a heat exchanger, the water tank has a water inlet pipe arranged on the inner wall of the bucket, so as to ensure that the outer half circle of the water inlet pipe is connected with a semicircular groove around the inner wall of the bucket; the semicircle of a fin is vertically connected with the inner half circle of the water inlet pipe, so as to form a four-surface heat exchange system; when gas is burnt, the water flowing through four surfaces can be heated first, and then the heat exchanger at the upper end of the bucket reheats the water. Therefore, high-temperature heat value can be fully and reasonably utilized, so as to achieve the aims of saving energy and increasing heat.

Description

Gas fired water heater energy-saving booster water tank

Technical field

The utility model relates to a kind of gas fired water heater energy-saving booster water tank.

Background technology

Water tank in the various gas heaters of family's use now, its case bucket all is that one deck book copper coin is made, around the case bucket outside by water inlet pipe around up connecting the upper end heat exchanger, behind fuel gas buring, be heated around the bucket wall and produce very high temperature, the heat exchange of failing effectively to carry out of this moment bucket wall and peripheral water inlet pipe is run away most of high temperature in vain, causes heat-energy losses.Although and the high temperature of up flowing through has been carried out heat exchange by interchanger to water in managing, but some high temperature do not make full use of and just runs off in vain with flue, caused the loss of heat energy yet.

Summary of the invention

The purpose of this utility model provides a kind of novel gas boiler, and it can not only save the energy, and can increase the thermal efficiency.

The purpose of this utility model realizes like this: at first make rectangular rectangle case barrel, the bucket inwall has a recessed from inside to outside semi-circular groove, this groove lies around a few from lower wall, then water inlet pipe is installed in the water tank bucket in these grooves, the outer half of circle of water inlet pipe is connected with the groove semicircle, form the wall tube heat exchange structure of four faces, inner half of circle of water inlet pipe and installation fin, make that a plurality of semicircles of half of circle and several fins are vertical in the many water inlet pipes that are arranged in parallel is connected and tiltedly is connected, the finned tube heat exchange structure of forming four faces, install in case bucket upper end a main heat exchanger structure is set, couple together with water inlet pipe on the dish.Setting by three heat exchange structures, formed a novel multiple heat exchange systems, behind fuel gas buring, at first interior four the face fins on every side of water tank bucket are heated generation high temperature, exchange in the water inlet pipe water of flowing through is heated, also produce high temperature around the bucket wall simultaneously, exchange to water inlet pipe, the also water heating to flowing through is through so circulation heating, water to the upper end higher temperature has been arranged, enter main heat exchanger then and heat at last.Heat exchange by three kinds of structure circulations has prolonged the time to the water heating, has increased the area to the water heating, has fully rationally utilized the high temperature calorific value of fuel gas buring, thereby has improved the thermal efficiency effectively, reaches the purpose of energy-saving booster.

The utility model just is installed into water pipe all around in the water tank bucket, utilize water inlet pipe and a bucket wall, fin to form heat exchanger, and the starting point is to improve, and manufacturing technology is not had specific (special) requirements, so the manufacturing of water tank is simple, and easy operation.

The specific embodiment

From Fig. 1, Fig. 2 as can be seen, inwall half slot (8) in the water tank bucket (1) is on bottom plate, lie around a few, wherein form trapezoidal being arranged in parallel at front, back, left surface, form tiltedly at right flank and to be arranged in parallel, a groove becomes horizontal bottom, and water inlet pipe (2) just is installed in these half slots, the outer half of pipe of water inlet pipe (2) is connected with half slot (8), forms wall tube heat exchange structure.Water inlet pipe (2) behind the connection half slot forms trapezoidal being arranged in parallel at front, back, left surface, and right flank forms tiltedly and is arranged in parallel.One becomes the straight horizontal horn shape bottom, the a plurality of semicircle orifices of positive semicircle fin (3) side among Fig. 1, Fig. 2, front, back, the left surface of its hole in the case bucket justified vertical the connection with inner one side of something of many water inlet pipes that the formation trapezoidal shape is arranged in parallel, vertically be arranged in parallel between the positive semicircle fin, form the finned tube heat exchange structure.Half of round-formed oblique connection the in a plurality of ellipse semicircle of ellipse positive semicircle fin (6) and the many water inlet pipes in Fig. 2, but half of circle is vertical the connection in last positive semicircle orifice of lower end and water inlet pipe, ellipse semicircle fin (7) tiltedly connects with the interior semicircle of many oblique parallel water inlet pipes, vertically be arranged in parallel between ellipse positive semicircle fin (6), the ellipse semicircle fin (7), form right flank finned tube heat exchange structure.

From the front view of the ellipse positive semicircle fin of right flank shown in Figure 3 (6) as can be seen, semicircle orifice bottom is positive semicircle, other all is ellipse semicircle, this be because right flank bottom water inlet pipe be the straight horizontal horn shape, other all is oblique parallel shape, horizontal vertical cross-section is just round, skewed vertical cross-section is oval, therefore, first semicircle orifice of fin (6) lower end is positive semicircle, other is ellipse semicircle, and the semicircle of fin (7) all is ellipse semicircle, and such two kinds of fins could tiltedly be connected with vertical with half of circle in the water inlet pipe (2) and be connected.All rolling at the semicircle of four whole fins of face has square semicircle limit, is used for vertically connecting half of circle in the water inlet pipe, can increase contact-making surface.Main heat exchange (4) is installed in case bucket top in Fig. 1, and around the connecting box bucket upper end, the water inlet pipe (2) on there is water inlet on its right and coils docks, and outlet pipe (5) is positioned at left surface.

Above-described water tank is a concrete structure, its operation principle is: after the fuel gas buring while, cold water flowed into water inlet pipe (2), the semicircle finned tube heat exchange structure of four faces begins to be heated in the case bucket, then the water of heat exchange in the water inlet pipe, simultaneously the wall tube heat exchange structure of four faces is also the water of the heat exchange that is subjected in the water inlet pipe, four water in the face of the water inlet pipe of flowing through by two structures circulate after the heating from top to bottom, water to the upper end had a higher temperature, enter main heat exchanger (4) then and heat at last, the temperature of water is improved the back rapidly once more and is flowed out from outlet pipe (5).
