Abstract
The utility model discloses an improved structure of a water tank of a gas water heater. According to the improved structure of the water tank of the gas water heater, heat exchange pipes forming a snake-type bending shape and a plurality of mutually parallel heat transfer sheets are arranged in the water tank, the heat transfer sheets are vertically arranged on the upper part in the water tank, and the heat exchange pipes are transversely arranged and bent outside the water tank; the heat exchange pipes are divided into a pre-heating pipe and a heat transfer pipe, and the heat transfer pipe passes through in the heat transfer sheets; the starting end of the pre-heating pipe is connected with a tap water pipeline outside the water tank, and the tail end of the pre-heating pipe is connected with the heat transfer pipe; the tail end of the heat transfer pipe is a hot water outlet of the water tank; and the cross section of the heat transfer pipe is an ellipse. Because the cross section of the heat transfer pipe of the utility model is the ellipse, under the condition of the same cross section area, the perimeter of the ellipse is longer than the perimeter of a circle in the prior art, so that the heat exchange area is improved, that is to say, under the conditions of the same flow rate and the same outlet water temperature, heat exchange efficiency of the water tank of the utility model is higher than that of the prior art, and gas and energy can be saved more.
Description
Technical field
The utility model relates to a kind of water tank of gas heater, the gas heater cisten mechanism of a kind of improvement specifically.
Background technology
Water tank is the parts of the thermal energy transfer in the gas heater, therefore also is called as heat exchanger, and its planform is related to the efficient that heat is transmitted, and is related to energy-conservation.The cisten mechanism of existing one type of gas heater is following: as depicted in figs. 1 and 2; Be provided with the heat-exchange tube and the some heat transfer sheet A3 that is arranged in parallel that are the serpentine bend shape in the water tank A1, heat transfer sheet vertically is arranged at the water tank internal upper part, and heat-exchange tube is horizontally set and bends in the water tank outside; Heat-exchange tube is divided into economizer bank A21 and heat-transfer pipe A22; Heat-transfer pipe is through in some heat transfer sheets, and the initiating terminal of economizer bank is connected with the outside water supply pipe of water tank, and cold water gets into from the initiating terminal of economizer bank; The end of economizer bank is connected with heat-transfer pipe, and the end of heat-transfer pipe is the hot water outlet of water tank.There is disadvantage in the cisten mechanism of the gas heater of above-mentioned prior art: as shown in Figure 2; The cross section of heat-exchange tube (heat-transfer pipe A22 and economizer bank A21) is circular; And can know that by how much general knowledge under the identical situation of sectional area, circular girth is minimum in the geometry; Therefore the heat exchange area of the heat-exchange tube of above-mentioned prior art (girth and length are long-pending) is less, causes heat exchange efficiency not high.
The utility model content
In order to overcome above-mentioned defective; The utility model provides a kind of gas heater water tank to improve structure, and this gas heater water tank improves structure the shape of heat-exchange tube is improved, and can improve the heat exchange efficiency of water tank; Play energy-conserving action, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of gas heater water tank improves structure, is provided with the heat-exchange tube and the some heat transfer sheets that is arranged in parallel that are the serpentine bend shape in the water tank, and heat transfer sheet vertically is arranged at the water tank internal upper part; Heat-exchange tube is horizontally set and bends in the water tank outside; Heat-exchange tube is divided into economizer bank and heat-transfer pipe, and heat-transfer pipe is through in the heat transfer sheet, and the initiating terminal of economizer bank is connected with the outside water supply pipe of water tank; Cold water gets into from the initiating terminal of economizer bank; The end of economizer bank is connected with heat-transfer pipe, and the end of heat-transfer pipe is the hot water outlet of water tank, and the cross section of said heat-transfer pipe is oval.Because the cross section of the utility model heat-transfer pipe is oval, under the long-pending situation of same cross-sectional, oval-shaped girth is greater than the circular girth of prior art; Therefore improved heat exchange area; Promptly under the identical situation identical with leaving water temperature of flow, time and area that the oval-shaped heat-transfer pipe of the utility model contacts with hot gas all are greater than the prior art round tube, so the water tank of the utility model is higher than the water tank heat exchanger effectiveness of prior art; Can practice thrift combustion gas, promptly more energy-conservation.
Preferably, the cross section of said economizer bank is an oval shape.The economizer bank of the oval shape economizer bank circular with respect to prior art improved heat exchange efficiency, in like manner improves the principle of heat exchange efficiency in above-mentioned oval-shaped heat-transfer pipe.
The beneficial effect of the utility model is: the gas heater water tank of the utility model improves structure, and the cross section of its heat-transfer pipe is oval, can be known by how much general knowledge; Under the long-pending situation of same cross-sectional, therefore oval-shaped girth has improved heat exchange area greater than the circular girth of prior art; Promptly under the identical situation identical of flow with leaving water temperature; The water tank of the utility model is higher than the water tank heat exchanger effectiveness of prior art, can practice thrift combustion gas, and is promptly more energy-conservation.
