Abstract

The invention discloses an improved structure for a water tank of a gas water heater. An S-shaped heat exchange pipe and a plurality of parallelly-arranged heat transmission sheets are arranged in the water tank, the heat transmission sheets are vertically arranged on the upper portion in the water tank, and the heat exchange pipe are arranged transversely and bent on the outer side of the water tank. The heat exchange pipe is divided into a preheating pipe and a heat transmission pipe, the heat transmission pipe penetrates through the heat transmission sheets, the starting end of the preheating pipe is connected with a tap water pipeline on the outer side of the water tank, the tail end of the preheating pipe is connected with the heat transmission pipe, the tail end of the heat transmission pipe serves as a hot water outlet of the water tank, and the cross section of the heat transmission pipe is in a shape of oval. Due to the fact that the cross section of the heat transmission pipe is in a shape of an oval, under the condition of the same cross section, the perimeter of the oval is larger than that of a circle in the prior art, therefore heat exchange area is increased. Namely under the condition of the same flow and water outlet temperature, compared with the prior art, the water tank is high in heat exchange efficiency, and can save gas, namely is energy-saving.

Description

The gas heater water tank improves structure
Technical field
The present invention 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.
Summary of the invention
In order to overcome above-mentioned defective; The invention provides a kind of gas heater water tank and improve structure, 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 present invention 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 heat-transfer pipe of the present invention 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 present invention contacts with hot gas all are greater than the prior art round tube, and therefore water tank of the present invention 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 invention has the beneficial effects as follows: gas heater water tank of the present invention 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; Water tank of the present invention is higher than the water tank heat exchanger effectiveness of prior art, can practice thrift combustion gas, and is promptly more energy-conservation.

The specific embodiment
Embodiment: a kind of gas heater water tank improves structure; Be provided with the heat-exchange tube and the some heat transfer sheets that is arranged in parallel 3 that are the serpentine bend shape in the water tank 1, heat transfer sheet 3 vertically is arranged at water tank 1 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 21 and heat-transfer pipe 22; Heat-transfer pipe 22 is through in the heat transfer sheet 3, and the initiating terminal of economizer bank 21 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 21 is connected with heat-transfer pipe 22; The end of heat-transfer pipe is the hot water outlet of water tank, and the cross section of said heat-transfer pipe 22 is oval, and the cross section of said economizer bank 21 is an oval shape.
