Background technology
In the prior art, the gas heater heat exchanger of red copper material in use, the flow through straight tube of heat exchanger of domestic water is heated the back and uses for the user.Owing to contact with the aqueous solution, can form a kind of micro cell in the water pipe pipe, also claim corrosion cell, cause water pipe couple corrosion from the inside to the outside, the water pipe of the heat exchanger made of aluminium/aluminium alloy particularly, the chemical activity of aluminium/aluminium alloy is stronger than red copper, and its couple corrosion speed is faster, cause making the water pipe perforation that is corroded, reduce the service life of heat exchanger.For overcoming above-mentioned defective, heat exchanger is developed.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of anticorrosion heat exchanger will be provided, and it can effectively improve the antiseptic property of heat exchanger, prolongs the service life of heat exchanger.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of combustion gas tool corrosion-proof heat exchanger, comprise water tank shell, water inlet pipe, outlet pipe, straight tube and heat exchange fin, the water tank shell surrounds exhaust gases passes, straight tube crosses exhaust gases passes and is fixed on the water tank shell, heat exchange fin is located in the exhaust gases passes and stacked being through on the straight tube successively, straight tube is communicated with water inlet pipe and outlet pipe, is set with anticorrosion in the described straight tube.
This combustion gas tool corrosion-proof heat exchanger also comprises the U-shaped pipe that is arranged on the water tank shell outside, and U-shaped pipe is communicated with two adjacent straight tubes, and the straight tube that crosses exhaust gases passes is connected into a unidirectional water route.Unidirectional water route one end is communicated with water inlet pipe, and the other end is communicated with outlet pipe.
Preferably, U-shaped external diameter of pipe is less than the straight tube internal diameter, and U-shaped tube end stretches into straight tube and is sealedly and fixedly connected with straight tube, and anticorrosion end face cramping by U-shaped pipe is fixed in the straight tube, is conducive to anticorrosion fixed installation in straight tube.
Preferably, anticorrosion otch that is provided with the band flange plays the effect of flow-disturbing with the water to the straight tube of flowing through, and makes even water temperature, and reduces the noise of high temperature current.
The shape of described flange can be circular arc, trapezoidal or square.
Preferably, described flange is provided with more than 2, and per two adjacent flange are separately positioned on anticorrosion two different sides, flow-disturbing better effects if like this.
Described anticorrosion is the chemical activity metal material manufacturings stronger than straight tube such as magnesium/magnesium alloy material, effectively make anticorrosion preferentially to be corroded, and the inner tubal wall of straight tube is protected.
Described heat exchanger is by aluminium/aluminum alloy materials manufacturing.
As another kind of scheme of the present utility model, branch water box and collecting box in the water tank shell outside, an end of straight tube is communicated with water inlet pipe by dividing the water box, and the other end of straight tube is communicated with outlet pipe by collecting box.
The utility model is compared the beneficial effect that produces with background technology:
Because the utility model adopts and fixedly install anticorrosion in the straight tube of combustion gas tool corrosion-proof heat exchanger, so can effectively improve the antiseptic property of combustion gas tool heat exchanger, prolong the service life of heat exchanger.

The specific embodiment
For example the utility model is further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, combustion gas tool corrosion-proof heat exchanger shown in Figure 7, mainly comprise water tank shell 1, heat exchange fin 5, straight tube 4, water inlet pipe 2, outlet pipe 3, U-shaped pipe 7, anticorrosion 6.
Water tank shell 1 surrounds exhaust gases passes, straight tube 4 crosses exhaust gases passes and is fixed on the water tank shell 1, heat exchange fin 5 is located in the exhaust gases passes and stacked being through on the straight tube 4 successively, U-shaped pipe 7 is arranged on the outside of water tank shell 1, U-shaped pipe 7 is communicated with two adjacent straight tubes 4, the straight tube 4 that crosses exhaust gases passes is connected into a unidirectional water route, and unidirectional water route one end is communicated with water inlet pipe 2, and the other end is communicated with outlet pipe 3.
Be set with anticorrosion 6 in the straight tube 4.The external diameter of U-shaped pipe 7 is less than the internal diameter of straight tube 4, and straight tube 4 is stretched at the both ends of U-shaped pipe 7 respectively, and is sealedly and fixedly connected with straight tube 4, and the anticorrosion 6 end face cramping by U-shaped pipe 7 is fixed in the straight tube 4, so that anticorrosion 6 fixed installation in straight tube 4.
