Problems solved by technology

[0002] Traditional gas-fired wall-hung boilers are usually equipped with corresponding devices such as combustion chambers and heat exchangers. Because the flue gas takes away a considerable part of the energy, the thermal efficiency is limited and the heat utilization rate is difficult to improve. A set of flue gas secondary condensation system is added on the top. The combustion chamber heats the main heat exchanger by burning gas to genera...

Example Embodiment

[0012] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application The features in the embodiments and the embodiments can be combined with each other.
[0013] Such as figure 1 , 2 As shown, the water container cover type water heater includes a heat exchange tube assembly, a flue gas flow guide plate, a smoke partition plate and a water container. The water container is also provided with a cover 3, which is made of USU304 stainless steel The water inlet 11 and the water outlet 12 on the water container 5 are respectively provided with threaded joints 4, and the cover 3 is provided with through holes 13 corresponding to the water inlet 11 and the water outlet 12, and the cover The upper part of the water container is fixedly connected with the screw 1, the threaded joint passes upward through the through hole on the corresponding cover and the hexagon nut 2 is fixed.
[0014] The surface of the heat exchange tube assembly is plated with a corrosion-resistant coating film. The heat exchange tube assembly is composed of a plurality of U-shaped long copper tubes 6 and a plurality of U-shaped short copper tubes 14, and the U-shaped long copper tubes 6 and the U-shaped short copper tubes 14 are staggered. The two ends of each heat exchange U-shaped copper tube in the heat exchange tube assembly communicate with the water container 5, and the water inlet 11 on the water container 5 communicates with one end of all the heat exchange U-shaped copper tubes, and the water outlet 12 is connected to the other end of all heat exchange U-shaped copper tubes, the flue gas flow guide plate 7 is placed on both sides of the heat exchange tube assembly, and the smoke partition plate 9 is placed in the middle of the heat exchange tube assembly. Using copper-nickel alloy or red copper as the base material, the surface is coated with a layer of good properties, dense, uniform and smooth, especially for the corrosion resistance of the flue gas condensate, which not only effectively improves the corrosion resistance of the heat exchanger, but also enhances the heat exchanger The heat transfer performance.
[0015] A water heater further includes a fixing seat 8 on which clamping grooves 10 are distributed, and the heat exchange U-shaped copper tube of the heat exchange tube assembly is clamped in the clamping groove 10. The pipe clamp for stabilizing the copper pipe effectively fixes the copper pipe, so that the distance between the heat exchange copper pipes is uniform, and the heat exchange with the high-temperature flue gas is stable and consistent. The use of multi-tube heat exchange effectively reduces the water resistance and increases the flow of water; the staggered arrangement of the heat exchange tubes effectively causes the flue gas to turbulent flow and improves the heat exchange efficiency; the flue gas flow guide plate and the separator are mutually The effect is to make the high-temperature flue gas flow in an orderly manner according to the arrangement direction of the heat exchange copper pipes, and improve the heat exchange efficiency.
[0016] In short, although the present invention lists the above preferred embodiments, it should be noted that although those skilled in the art can make various changes and modifications, unless such changes and modifications deviate from the scope of the present invention, they should be included in Within the protection scope of the present invention.
