The above-mentioned roles of the added ingredients and the reasons for the limitation of dosage will be explained below. Silicon is used to improve strength. However, if the amount does not exceed 0.6% by weight, the improvement effect cannot be obtained. In addition, at the conventional brazing temperature, the maximum addition amount of silicon is about 1% by weight, but in the present invention, the addition amount of silicon can be increased because of the reduction in the brazing temperature. In addition, if the added amount does not exceed 1.2% by weight, the effect of silicon on improving strength is as good as that of the traditional refrigerant path components, but the Chinese standard (CNS) A4 specification < 210X297 mm ) (Please read the precautions on the back before filling the nest page).

Therefore, the upper limit of the amount of copper used is 2.5% by weight, and especially when the amount of addition is between 0.8 and 1.5% by weight, it shows stable characteristics. Manganese distributes the gold diaphragm compound in the alloy, and is an essential element for improving strength without reducing corrosion resistance. However, if the amount is less than 0.05% by weight, the strength will be insufficient. At the same time, if the added amount exceeds 2.0% by weight, the moldability will be reduced, resulting in cracking of the brazed solder during processing (such as assembly). Magnesium is present in the alloy as a solid solution and is a finely precipitated magnesium silicide phase to improve strength. However, if the amount used is less than 0.03% by weight, the strength improvement effect cannot be obtained. If the amount used exceeds 0.5% by weight 96, when the brazing is performed with a non-corrosive flux, the rib flux will Min II reacted, making brazing unsuccessful.

If the content does not exceed 1.2% by weight, iron may be contained in the alloy. Similarly, if the content does not exceed 5 weight 96, elements other than the above (such as boron) can also be included in the alloy separately, and the addition of these elements can make the texture of the thin block fine.

Invention Description (13) Diffusion into the brazing material, and a block is produced near the interface between the brazing material and the core material Low copper area, and that area will be the first to produce corrosion, so it will cause strong corrosion along with blistering. In the present invention, copper is added to the brazing material alloy in order to Avoiding the diffusion of copper from the core material into the brazing material, and does not produce a low copper area near the interface between the brazing material and the core material, thus improving the corrosion resistance. And, if brazing can be close to 5 8 (TC It is carried out under the temperature of non-conventional brazing at a temperature close to 60 (TC, the core material alloy will not melt, so the present invention has developed an alloy with a brazing temperature lower than that of the traditional brazing material alloy The role of each of the above added ingredients and the reasons for the amount limitation will be explained below. Silicon reduces the melting point of the alloy, but if its amount does not exceed 7.0% by weight, the decrease in melting point will be insufficient, and It is impossible to perform brazing at a temperature lower than 585 ° C. In addition, if the usage exceeds 12.0% by weight, the melting point rises instead, making brazing impossible at a temperature lower than 585 ° C It is carried out at a temperature. Copper lowers the melting point of the alloy and improves the fluidity of the brazing material. In addition, when an alloy added with copper is used as the refrigerant path-forming component, copper can be lifted. The external eroded part of the heat exchanger. That is, as described above, no low copper area will be generated near the boundary between the brazing material and the path forming component, thus improving the erosion resistance. At this time, if the copper The dosage does not exceed 0.1% of the most weight, the effect is not sufficient, at the same time, such as -15-this paper scale is applicable to China National Standard (CNS) A 4 specifications (210X297 mm) ..... .................................... line {Please read the precautions on the back first Fill this page}

When the amount of printed fruit copper in the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy exceeds 8.0% by weight, the potential of the brazing material will become too high and will first corrode the formation of the refrigerant path, which will reduce the rolling workability of the alloy. And reduce the corrosion resistance, making it unsuitable as a brazing material for brazing pieces for heat exchangers. For this reason, the dosage of Li is more than 0.5% by weight, and does not exceed 8.0 reset%, but when it is used between 0.5 and 3.5% by weight, it shows a stable waitability " In addition, when the amount is 0.8% by weight or more and not more than 3.0% by weight, the flowability and rolling processability of the brazing material are excellent, because if the amount does not exceed 0.8% by weight, the The melting point becomes higher, and if the amount exceeds 3.0% by weight, this characteristic will decrease. Iron can be used to solidify the crystalline particles after the brazing material is melted and solidifies, thereby increasing the strength of the brazing electrode. This is the purpose of adding iron. However, if the amount does not exceed D. 0 5% by weight, the effect is not enough, and at the same time, if the amount exceeds 0.5% by weight, when the brazing material solidifies, it will form a gold hurricane compound, making it corrosive origin. Especially when the amount is not more than 0.4% by weight, the addition of β zinc with excellent external ketone corrosion lowers the melting point of the alloy. In addition, as described in the present invention, if copper is added to the brazing material alloy, the phenomenon of foaming due to external corrosion will be suppressed, but the potential of the brazing material will become higher than the core material. Therefore, at higher speeds, the problem of the formation of pit-like external pits will arise. For this reason, the addition of zinc is used -1 6-This paper standard is used in the middle of the family standard (CNS) A 4 specifications (210x297 mm) ................... .................................................. ................... ^ ................

Invention Instructions (15) to reduce hard The potential of the welding material, and the potential of the brazing material can be close to the potential of the core material, thus improving the corrosion resistance. However, if the amount is less than 0.5% by weight, this effect is insufficient, and if the amount exceeds 5 By weight%, the rolling workability of the alloy will be reduced, making it unsuitable for use as a brazing material for brazing of heat exchangers. In addition, after the fluidity of the Kalu brazing material, it is recommended The use amount is between 1 and 5 wt.%. The purpose of the addition of 洇 and tin is the same as that of zinc. That is, they can make the potential of the brazing material lower to improve the contact resistance of the refrigerant path forming component. If the amount does not exceed 0.002% by weight, the effect is not sufficient, and at the same time, if the amount exceeds 0.3% by weight, the rolling workability of the alloy will be reduced. The alloy composition of the brazing material is as described above. If they If the content of each does not exceed 0.05% by weight, it may contain inevitable impurity elements.

Description of the invention (recognition) JIS 7072 alloy is a representative traditional sacrifice Material alloy, but when this traditional sacrificial material alloy is combined with the core material alloy of high content of the present invention, the metal material added to the core material alloy will diffuse into the sacrificial material during brazing, and Suppresses the sacrificial effect of sacrificial materials. For this reason, it is possible to increase the zinc content in the sacrificial material, but if the zinc content is increased, the melting point of the sacrificial material is reduced, causing it to melt during brazing. However, in the present invention, since the aforementioned low melting point brazing material alloy is used, the zinc content can be increased. The addition of zinc can provide a sacrificial effect on the alloy. However, if the amount is less than 0.5% by weight, this effect is insufficient, and at the same time, if the amount exceeds 6.0% by weight, the melting point will be reduced, even if the brazing material alloy of the present invention is used, it will also lead to hard Melted during welding. The addition of 絪 and tin can also have a sacrificial effect on the alloy. However, if the amount is less than 0.002% by weight, this effect is insufficient, and at the same time, if the amount exceeds 0.3% by weight, the rolling workability of the alloy will be reduced, making it unsuitable as a sacrificial layer with a three-layer structure of brazing pads material. The addition of handcuffs can increase the strength of the sacrificial material alloy and improve the strength of the entire material. However, if the amount is less than 0.05% by weight, the effect of improving strength cannot be obtained. At the same time, if the usage exceeds 2.5% by weight, the melting point will be reduced. Even if the brazing material alloy of the present invention is used, it will lead to hard Melted during welding. The addition of manganese can also increase the strength of the sacrificial material alloy, and the head -1 8-This paper scale is applicable to the Chinese National Standard (CNS) A 4 specifications (210x297 mm) ......... .................................................. .......................

At the same time, if the amount exceeds 1.6% by weight, the rolling workability of the alloy will be reduced, making it unsuitable as a hard with a three-layer structure Sacrificial Material of Welding H》 The alloy composition in the sacrificial material of the present invention is as described above. Among the unavoidable impurities, if the content does not exceed 0.5% by weight, silicon may be included, but the content is preferably not more than 0.1% by weight. If the content does not exceed 0.8% by weight, iron may be included, but the optimal content is not more than 0.1% by weight. Similarly, other elements that are used to improve the strength and are different from the foregoing, such as chromium, knot, and titanium, may also be included in the composition of impurities, as long as the content of the other does not exceed 0.05% by weight. Next, the composition of the brazing pads used in the refrigerant path forming sheet (which is simultaneously plated with brazing pads on both sides of the core material) includes a combination of an aluminum alloy core material and an aluminum alloy brazing material, and This kind of aluminum alloy core material contains 0.6 wt% or more and not more than 2.5 wt% silicon, 0.5 wt% or more & not more than 2.5 wt% copper, 0.05 wt% or more and no more than 2.0 military % Manganese, or further containing at least one substance selected from the group consisting of: 0.03 weight% with h Η not more than 0.5% by weight, S, 0.03 weight% with h.

Invention description (18) Silicon not less than 12.0% by weight and 0.1% by weight And not more than 8.0% by weight of copper, 0.05% or more and not more than 0.5% by weight of iron, and further containing at least one substance selected from the following elements: 0.5% or more and not more than 5.5% by weight of zinc, 0.002% by weight % Or more and not more than 0.3% by weight of 絪, and 0.02% or more and not more than 0.3% by weight of tin, the remaining components are aluminum and some inevitable impurities. In other words, the alloy composition of these core materials and brazing materials is the same as the composition of the core materials and brazing materials of the brazing sheet used in pipes and headers, and the role of the added elements and The reason for the restriction is the same. Next, the brazing sheet β of the present invention for a high-strength aluminum alloy heat sink will be described. First, the development thinking will be explained below. When the aluminum alloy heat exchanger is manufactured by the above brazing technique, it is usually heated at a temperature close to 60 ° C. Since 60 ° C is a relatively high temperature for the fin material, the following is derived Three problems: namely, ① when heating, the heat sink bends, ② the intermetallic compound in the alloy reorganizes the solution, which reduces the thermal conductivity of the heat dissipation M, and ③ the low melting point and high strength alloy cannot be used.

The inventors have made continuous efforts to solve these problems and believe that it will be very effective for reducing the heating temperature of brazing. According to what the temperature should be, or how much the temperature should be reduced to solve this problem, after many studies, it was found that if the temperature is not higher than 5 8 5 ° C -2 0-This paper size is applicable to + country Standard (CNS) A 4 specifications (210x297 mm) ............................................ ................................................... f ...... .Ι.ΤΓ ..................... line (please read the precautions on the back before filling the nest page) Printed by Beigong Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs A6 B6 5. Description of the invention (19), during brazing, the heat dissipation H is difficult to bend, the reduction in thermal conductivity also becomes very light, and by increasing the amount of silicon added, the alloy can be improved Intensity 〇 These three issues will be explained in more detail. ① In most cases, the bending phenomenon of the heat sink is caused by the high temperature creep phenomenon caused by the heat sink at high temperature. We also found that a boundary line is formed near 5 90 ° C, and starts at a temperature above the heat dissipation Η When the temperature becomes fragile, this kind of creeping phenomenon will happen suddenly. For a reason, if the temperature is not higher than 585 ° C, the resulting phenomenon of cranking will not occur. In addition, there is a bending phenomenon caused by the diffusion of brazing material into the heat sink, but we found that a boundary line is formed near 5 9 5 ° C, and brazing will occur suddenly at a temperature above 595 ° C Material diffusion phenomenon. For this reason, if the temperature is not higher than 585 ° C, the diffusion phenomenon of the brazing material will be reduced, and the heat dissipation H will hardly bend. ② As the intergold compound precipitated in the aluminum alloy will recombine the solid solution during the brazing process, the thermal conductivity of the brazed heat sink will decrease. In addition, the higher the heating temperature, the higher the limit of forming a solid solution and the faster the diffusion speed, so that the reorganization of the solid solution can be easily performed. For these two reasons. We are keen: lowering the brazing temperature can increase the thermal conductivity, and if the temperature is not higher than 585 ° C, the speed of recombination of the solid solution is very low, and the focus is on the thermal conductivity There are very few reductions. ③ Regarding the strength, the elements added in order to make high-strength aluminum alloy-2 1-This paper scale is suitable for the Chinese National Standard (CNS) A 4 specifications (210x297 mm) ... ............., ΓΓ .................. line (please read the precautions on the back before filling this page) Economy A6 _ B6_ printed by the Ministry of Central Standards Bureau employee Xiao # Cooperative. V. Description of invention (20) Including copper, magnesium, silicon, etc. However, when aluminum alloy is used as a refrigerant path forming component, the corrosion resistance must be And brazeability is taken into consideration, and when aluminum alloy is used as a heat sink, the sacrifice effect, conductivity, heat and brazeability must be considered. Therefore, the elements that can improve the strength of the alloy and increase the amount of addition must be limited, and the addition of silicon is indeed affected by the honey. When brazing at a temperature of 600 ° C, the amount of silicon or copper that can be added is preferably as low as 1% by weight, but at 585 ° C or lower, the amount can be increased To 2.5 wt%. There is now known a method that enables brazing to be performed at a temperature lower than the general brazing temperature, and a method capable of brazing at around 50 ° C, which is called low temperature brazing (for example, Japanese unexamined Patent Bulletin, No. 1-107961). One problem with this method is that the brazing material is easily corroded after brazing, because aluminum-zinc alloys or zinc alloys with a zinc content of not less than 20% often It is used as a brazing material, so they are not actually used in the manufacture of heat exchangers. In addition, if the addition of zinc in aluminum-zinc alloy exceeds 8%, the rolling properties will be very alum Poor, making it difficult to manufacture brazing H by the method of lamination, so far there is no method that can be used to produce brazing H for low temperature brazing under stable conditions. Therefore, the brazing material must be in the form of a sheet The use of hard brazing materials limits the types of ingredients that can be produced. However, the inventors have found that: Even at temperatures not higher than 585 ° C (these two temperatures are much higher than the low temperature brazing temperature mentioned above) At the brazing temperature, the parts of the heat exchanger can also be improved, And R developed a suitable heat-dissipating H alloy, thus deriving the present invention. -2 2-This paper size is applicable _National H Family Standard (CNS) A 4 specifications (210x297 mm) .......... .................................................. .......................................................

However, heat exchangers are large objects, and when they are industrially brazed, the temperature will vary by about 5 to 10 ° C everywhere. For this reason, the temperature to be maintained when brazing the heat exchanger is slightly higher than this lower limit by at least 5 to 10 ° C. In other words, first of all, it can be seen that the 4047 alloy and the 4N04 alloy seem to be brazing material alloys that can be used in the same temperature range as the brazing material of the present invention, but in fact they are different. Fail 1: Brazing is completed at a temperature where the brazing material alloy of the present invention is used for brazing. Although alloy 4145 is a brazing material that can be brazed in the temperature range where the brazing material alloy of the present invention is brazed, it has never been used as a brazing material for heat exchangers used in heat exchangers. material. The detailed reason will be described in the description of the composition limitation of the brazing material of the present invention, but the difference between the composition of the 4145 alloy and the present invention is that it has a higher iron than the brazing material alloy of the present invention The upper limit of the content is not added with zinc, blur and tin, so the external corrosion resistance is not good. For this reason, we already know that the brazing temperature of the heat exchanger is not higher than 5 8 5 ° C as mentioned in the present invention. In addition, U.S. Patent No. 3, 9 ί, 6 9 5 傜 relates to a brazing alloy, but the focus is on the development of core material alloys, the core material can be plated with any Zen brazing material.

V. Description of the invention (25) In Example 4, it can be seen that there is no description of the brazing material at all, and it can also be seen from the fact that the reason for the addition of alloy elements is not explained. In this invention, the description of brazing materials only occupies 12 lines, and also from page 40, line 40 to page 2, line 52, and alloys (4 3 4 3, 4 1 4 5, 4, The difference between 0 4 7, 4 0 4 5 and X 4 0 0 4) is described by an example, and the brazing material of the present invention is as described above. In addition to this, the brazing material described in this invention differs from the brazing material of the present invention in the following points. ① It is confirmed that the way of adding magnesium is different from the present invention. If you add m, the flux and iM will react during brazing, making brazing impossible. ② The composition range of zinc is wide. When the zinc content of the alloy exceeds 6%, in the case of the content of silicon, copper and iron of the present invention, the rolling workability is not good and it cannot be converted into a brazed sheet. ③ The iron content is not adjusted. Therefore, there are problems in rolling workability and external corrosion resistance. D ④ R has the melting point of the brazing material, but there is no description of the brazing temperature. At this time, the core material of the first brazed sheet of the present invention for aluminum alloy heat sink is an aluminum alloy, which contains 0.03% of the military and h and does not exceed 2.5% of the most silicon, 0.05% of the most heavy iron h R does not exceed 2.0% by weight of iron. 0.05% of the most heavy iron h does not exceed 2.0% of the heavy copper, 0.6% of the weight of the house 1: And no more than 2.0% of manganese, and further contains Xin Shao a substance selected from the following elements: 0.05% of Zhang Zu% to Bu.

The reasons for the above-mentioned roles of the added ingredients and the limitation of the dosage will be explained below. Silicon can be used to improve strength. However, if the amount does not exceed 0.03% by weight, the effect of improving strength cannot be obtained. At the conventional brazing temperature, the maximum addition amount of silicon is about 1% by weight. However, in the present invention, the addition amount of silicon can be increased due to the reduction of the brazing temperature. In other words, if the added amount does not exceed 1.2% by weight, the effect of silicon on improving strength is as high as that of conventional heat dissipation H, but if the amount exceeds 1.2% by weight, a greater strength improvement than traditional heat sinks can be obtained effect. In addition, when the amount of silicon added increases, the thermal conductivity will decrease. Therefore, when manufacturing a heat exchanger, it is necessary to consider the importance between strength and thermal conductivity to select its composition. In addition, if the amount of silicon added exceeds 2.5% by weight, the core material will start to melt even at the brazing temperature of the present invention.

When the printing volume of the Beigong Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs does not exceed 0.05% by weight, the effect is not sufficient; The diffusion of the solder material becomes significant, so that the flattened dysprosium of the heat sink can improve the strength of the alloy. If the content of copper does not exceed 0.5% by weight, the effect of improving strength cannot be achieved, and at the same time, if the amount of the net exceeds 2.0% by weight, the core material will start to melt even at the brazing temperature of the present invention. Manganese forms a fine intermetallic compound in the alloy, and not R can improve the strength, and at the same time & avoid recrystallized grains becoming fine when brazing heating. If its amount does not exceed 0.6% by weight, it cannot be At the same time, the effect of improving the strength is obtained. At the same time, if the addition amount exceeds 2.0% by weight, the moldability of the heat dissipation H will decrease, making it impossible to make a wavy mold. Zinc, indium, and tin are used to provide heat dissipation. The sacrificial anode effect. The added element β. If the alloy doped with copper is similar to the alloy of the present invention (if these elements are not added), the potential of the heat sink will become It has a higher potential than the components of the refrigerant path, thereby reducing corrosion resistance. At the same time, if the content of zinc does not exceed 0.05% by weight, the amount of 絪 does not exceed 0.002% by weight, and the amount of tin does not exceed 0.002% by weight, this effect will be insufficient, and if the amount of zinc exceeds 5.0% by weight, When the amount of Lang added exceeds 0.3% by weight, and the amount of tin exceeds 0.3% by weight, the thermal conductivity will decrease. It is to be noted that in the present invention, when the amount of copper added is high, more zinc needs to be added, but because zinc will reduce the melting point of the alloy-2 9-This paper standard is used in the national standard (CNS) A 4 Specification (210x297mm) .................................................. ....................................... pretend ... ..............

If the content of magnesium does not exceed 0.03% by weight, the use of nickel does not exceed 0.05% by weight, and the amount of giant thorium does not exceed 0.03% by weight, the improvement effect cannot be obtained. On the other hand, the amount of magnesium added When it exceeds 0.5% by weight, the brazing property will be reduced, and if the amount of nickel added exceeds 2.0% by weight, and the amount of Ming, knot, and titanium exceeds 0.3% by weight, the moldability will be reduced, and it will be difficult to mold the heat dissipation.

In the present invention, this kind of brazing material and brazing material H are pseudo-used, and brazing is performed in a temperature range of 5 70 to 585 ° C. This is because if the brazing temperature is lower than 570 ° C, a part of the composition will not melt into the brazing material of the present invention, and brazing cannot be performed. Similarly, if the temperature is higher than 585 ° C, the thermal conductivity of the heat dissipation H will be reduced (as described above U and the bending properties at high temperatures will also be reduced, resulting in further melting β. In addition, in this way To reduce the brazing temperature, it can extend the life of the brazing furnace and improve the corrosion resistance of the refrigerant path forming components. Although the brazing conditions of the present invention limit the temperature range, other conditions can be compared with the traditional brazing conditions Maintain the same. In other words, the fusion brazing method, the H 〇c 〇〇〇 brazing method using a non-corrosive rib flux (fluoride type, absolute type), etc., can be used directly without special restrictions. Before brazing, if necessary, you can carry out Tai-install and Qing-3 in the traditional way. 2-This paper standard uses the Chinese National Standard (CNS) A4 specification (210x297 mm) ...... .................................................. .............................

In this case, even if a rib flux (for example, an rib flux with an absolute shape) is used, brazing can still be performed within the temperature range of the present invention. In addition, in the present invention, The treatment procedure after heating is not particularly limited. That is, the procedures such as treatment, removal of rib flux and paint can be performed up to this point. To produce ingots, however, it can be manufactured through the procedures of hot rolling (multilayer rolling) and cold rolling-annealing, or it can also be produced through the procedures of continuous casting rolling and cold rolling-annealing. , These examples will be used to explain the present invention more specifically. Example 1 The present invention has a three-layer structure (including brazing materials, core materials and sacrificial materials) aluminum alloy brazing pads, used for heat dissipation The flat tubes and headers of the device are tested in the following manner: Using the alloy composition shown in Table 3 to Table 9, the core material, brazing material and sacrificial material are joined together, and Borrow the general method Method to produce a three-layer structure with a huge thickness of 0.25 mm brazed pads. The rate of electroplating of the brazing material is 0%, and the rate of electroplating of sacrificial material is 15%. In addition, in sacrificial materials, iron and silicon are impurity elements, and their content (others have the most range between 0.01 to 0.2% and the most weight. This ® hard soldering Η in Table 10 to Table 1 2 under the temperature conditions, placed in nitrogen heating „Braking the brazing material part of the brazing Η outward, 3-3-This paper standard uses the Chinese standard (CNS) A 4 Specifications (210x297mm) Pack ....................

Description of the invention (32) The material part is facing inwards, and after the brazing Η is heated, the tensile test, external corrosion resistance test and internal corrosion resistance are performed Sexual testing. In the external corrosion resistance tide test, only the middle part of the surface of the brazing material is exposed, and the other faces are sealed, and then a 360-hour CASS (JIS H 8 6 8 1) test is performed to check the location where pitting occurs. In the internal corrosion resistance test, the brazing pad partially masked with the brazing material is immersed in tap water with 10 pp β of Cu2 + Ran ion for 5 months, and who will do 8 0 ° CX 8 hours and Periodic corrosion test at room temperature X 16 hours. Then, under the optical display mirror, the depth of focus is used to determine the depth of pitting generated on the surface of the sled material. These results will be listed in Table 10 to Table 12. (Please read the precautions on the back before filling the nest page). Binding.

It can be clearly seen from Tables 22 and 23 It is found that the brazing sheet of the present invention does not melt during brazing, has high strength, and is also excellent in corrosion resistance. However, in Comparative Examples 67, 68, 73, and 74, the core material is beyond the scope of the present invention, and even when brazing is performed at 575 ° C, it will start to melt. In Comparative Examples 6.9 and 7.5, the brazing material does not contain zinc, condensate, and tin, making its corrosion resistance lower. In Comparative Examples 70, 71, 76, and 77, the brazing material is beyond the scope of the present invention, because the brazing material does not melt at a temperature of 585 ° C (or lower), and therefore at 6G0 ° C Under the heating, but at this time the core material began to melt. In Comparative Examples 72 and 78, the amount of copper and zinc in the brazing material is greater than the range listed in the present invention, and the phenomenon of cracking occurs during rolling, making it impossible to make brazing H. In the conventional example 79, its strength is inferior to that of the brazed pad of the example of the present invention. In the conventional example 80, it contains a lot of copper in the core material, so the corrosion resistance is not good.

Example 5 Fabrication of a brazed fin material having the alloy composition shown in Tables 26 to 29 (whose brazing material is plated on both sides of the core material). In other words, the heat dissipation of these brazing materials is 0.1 mm thick H14 refining material (won each side is coated with 10% brazing material on both sides of the core material). At the same time, these hard soldered heat dissipating H materials numbered 1 to 67 will be heated under nitrogen under the conditions shown in Tables 30 and 31 to perform sag test and tensile test. And these results are listed in Tables 30 and 31. The sagging test was carried out under a protruding length of 50 mm. In addition, in the tension tide test, the brazing material is present on the surface of the brazing H heat dissipation H, and it is difficult to accurately determine the cross-sectional product of the heat dissipation H after brazing heating. Credibility is not enough. Therefore, for the strength values, in the rightmost cabinet of Tables 26 to 29, 0.06 mm thick heat-dissipating Η bare material (the alloy composition and the alloy that constitutes the core material of these hard solder heat-dissipating Η materials are listed The composition is the same) the intensity tide is the most value.

Excellent, but all the fin materials of the present invention show excellent values. Example 6 A brazed fin material having the alloy composition shown in Tables 32 and 33 was manufactured (whose brazing material was plated on both sides of the core material). The thickness of the plates for making some brazed M heat dissipation H is 0.11 mm and is H14 refined (Jie plated 10% brazed material on both sides of the core material). These brazed pad heat sink materials will be heated under nitrogen under the conditions shown in Table 34 to perform the sag test Sift force tide test. At the same time, these results are listed in Table 34. The sagging test was performed at a protrusion length of 50 mm. In addition, in the tensile test, in a manner similar to that described in Example 5, a bare material having the same core material composition was used to replace the brazed H heat sink, and the same heating was applied to measure the tensile strength.

It has a lower natural potential, and the pitting of the cooling pipe is also shallow. Example 7 is manufactured with Table 36 To the alloy shown in 38 brazed H heat dissipation H material (which is coated on both sides of the core material with brazed material). The thickness of these brazed H heat dissipation H plates is G. 11 mm and is H14 refined (Ye is plated with 10% brazing material on both sides of the core material). These brazing pads dissipate heat Η materials, which will be heated under nitrogen under the conditions shown in Tables 39 and 40 to perform sag tests and tensile tests, and to measure electrical conductivity. At the same time, these results are listed in Tables 39 and 40. The sagging test was carried out under a protruding length of 50 mm. In addition, in the tensile test, similar to the method described in Example 5, a bare material with the same core material composition was used to replace the brazed fin heat sink, and the same heating was applied to measure the tensile strength. In addition, the conductivity of the brazed fin heat dissipation H is a measurement of replacing the brazed fin heat sink with the same composition of the bare material fin as the core material under the same phase thermal conditions. These are due to the brazed material Existing on the surface of these heat sinks M, and after brazing, it is difficult to accurately determine the cross-sectional area of the heat sink. It is known that the conductivity of the brazed fins is the same as that of the brazed H bare material containing the same core material. In addition, electrical conductivity is an indicator of thermal conductivity.

Example 8 Fabrication of a brazed H heat sink material having the alloy composition shown in Tables 41 to 43 (which is pseudo-coated with braze material on both sides of the core material). The thickness of these brazed H heat dissipation H plates is 0.11 mm and is a refined H14 (deposited on each side of the core material with 10% brazed material). These samples were made by cutting the heat sink, and under the conditions shown in Tables 44 and 45, brazing heating was carried out in nitrogen to perform the sag test. As for the sag test, it was carried out under a protruding length of 50 mm. In addition, the conductivity of the sample after being heated will be measured under the conditions listed in Tables 44 and 45. Except for the measurement of thinness, the measurement of the thinness is performed in a similar manner as shown in Example 7. These results will be listed in Tables 44 and 45. .....................................

This is because the melting point of the brazing material of the brazing H heat sink is low, so the test temperature is also set at a lower temperature. However, in the comparative example (34-59, 61, 62), the sagging properties and conductivity are poor β. This is because the melting point of the brazing material of the brazing fin heat sink is high, the temperature of the moisture test Therefore, it is set at the melting point of the brazing temperature-6Q (TC or 610 ° C higher temperature.

Description of the invention (8b) From Table 47, it can be clearly seen that the ① and Article ② does not cause the problem of heat dissipation Η collapse, and has good solderability and excellent thermal efficiency. Even if an aluminum alloy containing 1.2% by weight (or more) of silicon is used as a tube, it can also be maintained High strength without melting. However, in items ③ and ④ in the comparative example, Ye uses traditional brazing materials and the brazing temperature is 600 ° C. Comparative example ③ has low strength, And in the article of Comparative Example ④, since the aluminum alloy used in the tube contains 1.2% by weight (or more) of silicon, and the brazing temperature is as high as 6Gfl ° C, the tube will start to melt. As described above, according to the present invention, since the brazing material constituting the brazing material for manufacturing an aluminum alloy heat exchanger has a low melting point, it can be brazed at a relatively low temperature, so the brazed fin material The bending phenomenon and the reduction in thermal conductivity are less likely to occur, which makes it possible to thin the wall of the heat sink. In addition to the above, when using such a brazed sheet as a pipe or a flat material, these components will have high strength, excellent corrosion resistance, and can make the pipe and flat material thin and high strength, so for The dismantlement and weight reduction of the heat exchanger is the most reduced, and it has a very considerable effect.
