The present invention relates to a heat exchanger fin material having excellent high-temperature sag resistance, sacrificial anode effect, and thermal conductivity. Conventionally, in general, for example, automobile radiators,
Al alloy heat exchangers are widely used in air conditioning equipment and other equipment. This heat exchanger usually uses a brazing sheet made by cladding an Al-Si alloy brazing material on one or both sides of an Al alloy plate, or a fin material made of an Al alloy plate, and a fin material made of an Al alloy plate. ,
Alternatively, a pipe material formed from a brazing sheet made by cladding an Al-Si alloy brazing filler metal on the surface side of an Al alloy plate material in a vacuum or inert gas.
Or in the atmosphere using flux at 580-620℃
It is manufactured by brazing at a temperature of . Therefore, the heat exchanger fin material must have sufficient high-temperature sag resistance so as not to deform when heated to a temperature higher than the melting temperature of the filler metal during brazing, and a high heat fin material that exhibits good heat exchange performance after brazing. It is required to have good conductivity, as well as a sacrificial anode effect to protect the pipe material from corrosion and prevent pitting corrosion from developing into through holes. Currently, all of the vessel fin materials are inferior in at least one of the following properties: high-temperature sag resistance, thermal conductivity, and sacrificial anode effect. Therefore, from the above-mentioned viewpoints, the present inventors conducted research to develop a heat exchanger fin material that has high-temperature sag resistance, thermal conductivity, and sacrificial anode effect. (hereinafter % indicates weight %), contains Si: 0.1 to 0.8%, Zr: 0.02 to 0.2%,
Furthermore, if necessary, 1 of Cr: 0.05-0.3%, Cu: 0.05-0.7%
Zn: 0.3 to 2% on both sides of an Al alloy core material having a composition of Zn: 0.3 to 2%, and the remainder consisting of Al and unavoidable impurities. It is made by cladding the skin material of Al alloy with
When the heat exchanger fin material is composed of a layered composite board, the resulting heat exchanger fin material has excellent high temperature sag resistance and thermal conductivity due to the core material, while being superior to the core material. Since the electrochemically base material mentioned above ensures an excellent sacrificial anode effect, there is no deformation during brazing.
It was discovered that after brazing, it exhibits excellent thermal conductivity and sacrificial anode effect, making it possible to use the heat exchanger for an extremely long period of time. This invention has been made based on the above knowledge, and the reason why the composition of the core material and skin material constituting the three-layer composite board and the layer thickness of the skin material are limited as described above will be explained below. do. A Core material (a) Si and Zr These components are Al-Zr-Si, which combines with Al and is finely dispersed and precipitated in the substrate.
This Al-Zr-Si compound has the effect of increasing the recrystallization temperature of the core material, so the recrystallized grains become coarser during brazing heating, and these coarse recrystallized grains Excellent high-temperature sag resistance that does not cause deformation during brazing is ensured, and the Al-Zr-Si
The compound has the property of not inhibiting the excellent thermal conductivity of the Al substrate, so it maintains excellent thermal conductivity, but the content is less than 0.1% for Si and 0.02% for Zr, respectively.
%, it is not possible to secure the desired high temperature sag resistance, while Si: 0.8% and Zr: 0.2%
If the Al-
As the amount of Zr-Si compound becomes too large, the thermal conductivity tends to decrease.
The content is Si: 0.1~0.8%, respectively.
Zr: Set at 0.02 to 0.2%. (b) Cr The Cr component is bonded with Al to form an Al-Cr compound, which is dispersed and precipitated finely and uniformly in the substrate.
In particular, in coexistence with the above Al-Zr-Si compound, it has the effect of further promoting the coarsening of recrystallized grains and further improving the high-temperature sag resistance of the core material, so it may be included as necessary. However, if the content is less than 0.05%, the desired effect of improving high temperature sag resistance cannot be obtained, while if the content exceeds 0.3%, the thermal conductivity will decrease. from 0.05
It was set at 0.3%. (c) Cu The Cu component has the effect of improving the strength of the core material by forming a solid solution in the base material, so it is included as necessary when particularly high strength is required. If the content is less than 0.05%, the desired strength improvement effect cannot be obtained;
%, coarsening of recrystallized grains is inhibited and high-temperature sag resistance deteriorates, so the content was set at 0.05 to 0.7%. B Skin material (a) Zn The Zn component is made by electrochemically making the skin material less
However, the sacrificial anode has a sufficient effect and protects the pipe material from corrosion, but its content is
If the content is less than 0.3%, the desired sacrificial anode effect cannot be ensured, while if the content exceeds 2%, the skin material becomes electrochemically too base, promoting the sacrificial anode effect as a fin material. If too much Zn is used, not only will the amount of corrosion of the fin material itself increase, but also the amount of evaporation of Zn will increase, causing furnace contamination, especially during vacuum brazing, so the content should be reduced to 0.3
It was set at ~2%. Next, the heat exchanger fin material of the present invention will be specifically explained using examples. Al alloy 1 for core materials of the present invention having the compositions shown in Table 1 is produced by ordinary melting and casting method.
~13. Conventional Al alloys 1' and 2' for fin materials, Al alloys a to c for skin materials of the present invention, Al alloys for pipe materials, and Al alloys for brazing material for pipe materials are melted and cast to form ingots. did. The various Al alloy ingots obtained as a result were then hot-rolled to form hot-rolled sheets with a thickness of 8 mm, and the Al alloys 1' and 2' for conventional fin materials and Al alloys 1' and 2' for skin materials of the present invention were then hot rolled.
The Al alloys a to c and the Al alloy for the brazing material of the pipe material are cold rolled to form a cold rolled plate with a thickness of 1 mm, and then the Al alloy 1 for the core material of the present invention with a thickness of 8 mm is applied.
Cold-rolled plates of Al alloys a and b for skin materials of the present invention having a thickness of 1 mm were placed on both sides of the hot-rolled plates of ~13.
