Specific embodiment
With reference to the accompanying drawing, the present invention is further illustrated by way of embodiment, but is not therefore limited the invention to
Among following scope of embodiments.
As shown in Figure 1, condensing heat exchanger 10 includes: copper pipe 11, aluminum pipe 12, fin component 13.
Copper pipe 11 is inserted in aluminum pipe 12, and aluminum pipe 12 is inserted in fin component 13；Copper pipe 11 passes through high pressure gas tube expansion
Processing is fitted closely with aluminum pipe 12.
The condensing heat exchanger 10 reduces condensed water to copper pipe 11 in the form of internal copper pipe 11 and external aluminum pipe 12
To corrode and copper pipe 11, aluminum pipe 12 and fin component 13 are processed expanded joint by high pressure gas tube expansion and be integrated, technique is relatively simple,
And one-pass molding avoids that technique caused by three components are separately connected is cumbersome, and reliability is higher.
Heat-conducting medium layer is equipped between copper pipe 11 and aluminum pipe 12.
Heat-conducting medium layer is preferably thermal grease layer.Thermal grease layer with a thickness of micron order.
The thermal resistance of heat-conducting silicone grease is small, thermally conductive to be changed to by force, and main function is so that aluminum pipe 12 and copper pipe 11 are bonded more
Closely, the presence in gap is prevented.
Fin component 13 includes multiple fins, and multiple fins are parallel to each other and fit together, and the centre of multiple fins is set
There is through-hole, through-hole allows aluminum pipe 12 to be inserted into.Fin is for increasing heat dissipation area.
Fin component 13 is made of aluminum.
The corrosion resistance of aluminum member is higher, is not easy to be corroded, therefore can preferably resist corrosion of the condensed water to it,
And according to the pepe standard of household water, aluminum member cannot directly and potable water contact, therefore, internal 11 outside aluminum pipe of copper pipe
12 setting had not only met pepe standard but also can prevent from corroding.
As shown in Fig. 2, gas heater 20 includes condensing heat exchanger 10 as above.
Gas heater 20 further include: high-temperature heat-exchanging 21 and burner 22.
Burner 22 generates flue gas, and flue gas is introduced into high-temperature heat-exchanging 21 and is changed with the heat exchanger tube in high-temperature heat-exchanging 21
Heat enters back into condensing heat exchanger 10 and exchanges heat with the heat exchanger tube in condensing heat exchanger 10.And flue gas enters condensing heat exchanger 10
When, vapor therein can condense into condensed water in condensing heat exchanger 10 fin component 13 and aluminum pipe 12 contact.But it flows
The copper pipe 11 of the heat exchanger tube innermost layer of water flowing is corroded because not being contacted without with condensed water.
As shown in figure 3, the manufacturing method of condensing heat exchanger 10 includes the following steps:
S1: a copper pipe 11 is provided；
S2: providing an aluminum pipe 12, and copper pipe 11 is inserted into aluminum pipe 12；

S4: by being passed through high pressure gas into copper pipe 11, aluminum pipe 12, copper pipe 11 and 13 expanded joint of fin component are integrated.
In step s 2, it is inserted between aluminum pipe 12 by copper pipe 11, sprays one layer of heat-conducting medium in the outer surface of copper pipe 11.
The heat-conducting medium of spraying with a thickness of micron order.Heat-conducting medium is preferably heat-conducting silicone grease.
The thermal resistance of heat-conducting silicone grease is small, thermally conductive to be changed to by force, and main function is so that aluminum pipe 12 and copper pipe 11 are bonded more
Closely, the presence in gap is prevented.
Fin component 13 is made of aluminum.
The corrosion resistance of aluminum member is higher, is not easy to be corroded, therefore can preferably resist corrosion of the condensed water to it,
And according to the pepe standard of household water, aluminum member cannot directly and potable water contact, therefore, internal 11 outside aluminum pipe of copper pipe
12 setting had not only met pepe standard but also can prevent from corroding.
The condensing heat exchanger 10 reduces condensed water to copper pipe 11 in the form of internal copper pipe 11 and external aluminum pipe 12
To corrode and copper pipe 11, aluminum pipe 12 and fin component 13 are processed expanded joint by high pressure gas tube expansion and be integrated, technique is relatively simple,
And one-pass molding avoids that technique caused by three components are separately connected is cumbersome, and reliability is higher.
