Here comes the second half of the advantages of the shovel tooth radiator~🌞

1. The advantage of aluminum extrusion processing technology is low cost, but the disadvantage is that the length of heat dissipation teeth is limited by the thickness width ratio. The area of the radiator is limited, and the width of the mold is limited.

Large width aluminum profiles need to use ultra large tonnage extruders. These extruders are generally used for aluminum profile processing of high-speed rail and large aircraft. They belong to extreme manufacturing, with small quantities and high processing costs.

If the shovel tooth processing technology is used, the limitation of the thickness width ratio of the traditional radiator can be easily broken through, and the radiator with high heat dissipation density can be made. The blade is integrated with the base, and the thermal resistance is much smaller than that of the gear shaping welding process. It can also easily make a radiator with a particularly large width, and finally achieve ultra-high cost performance. The shovel tooth technology has great advantages in large-size and high heat dissipation requirements.

2. The insert makes the components feel all year round, and the shovel tooth radiator makes the components live in winter forever

3. Shovel teeth are the trend of radiators in the future. They are cooler than gear shapers and lighter than profiles.

4. High density and thin teeth make the heat dissipation performance better and stronger.

Why choose the shovel tooth radiator?

What are the advantages of the tooth radiator?

Next, let's talk about it in two parts (because there are so many)

1. The processing technology of the shovel tooth radiator is more transparent and clear, which can make customers understand more about their money.

2. The shovel tooth radiator is less limited in size and can be made wider and larger. It can be used for heat dissipation of machines with higher power.

3. When the customer's power and heat source are large, the aluminum extrusion radiator has a small number of cooling teeth due to the limitation of extrusion ratio, which makes the heat dissipation area in the limited heat dissipation space insufficient, so the heat dissipation effect cannot be achieved. The tooth shoveling process can well overcome these defects.

4. The tooth heat sink and the heat dissipation base plate are made of a profile without any connection points, and the heat conduction and heat dissipation efficiency can reach 100% of the profile material.

7005 aluminum alloy, with strength higher than 7003 alloy, has good welding performance and can be strengthened by heat treatment. 7005 aluminum alloy extrusion materials are often used to manufacture welded structures with both high strength and high fracture toughness, such as trusses, rods and containers of transportation vehicles; Large heat exchangers and parts that cannot be subject to solid fusion treatment after welding; It can also be used to make sports equipment such as tennis rackets and softball bats.

Main differences:

1. the commonly used materials for aluminum alloy frames are 7005 and 6061.

2.7000 series mainly uses zinc as the main alloy, and the composition proportion reaches 6%. The 6000 series is mainly made of magnesium and silicon, with a low proportion of total components.

3. in terms of strength, 7005 is stronger, but only slightly stronger. From the table, it can be seen that the yield strength is only stronger than 6061.

4. all aluminum alloys used as frame materials have been heat treated T6

5. on the whole, 6061 is a good material. Due to the high proportion of other metals in 7005, it is difficult to weld and handle. In particular, 7075 (the last two figures represent the proportion of alloy) has a higher proportion, so it can not be used as the material of the frame. In contrast, the 6061 has a low proportion of other metals, so it can increase its strength and reduce its wind resistance through special-shaped and various treatments, and even reduce its weight by pulling the pipe three times.

Difference between aluminum alloy and stainless steel

There are many aluminum alloy and stainless steel products in our life, such as our common pots, basins, doors and windows, etc.

The biggest difference between them is that aluminum alloy is generally light in weight and dark in color, while stainless steel is heavy and bright in color. In addition, they are different in price, hardness, performance, surface, use and so on.

1. Different prices

Stainless steel is expensive, aluminum alloy is cheap.

2. Different hardness

Aluminum alloy has low density but high strength, close to steel and good plasticity; Stainless steel is nickel chromium alloy with higher hardness than aluminum alloy.

3. Different high temperature resistance

Stainless steel can withstand high temperature, with a melting point of 1200-1500 ℃; Aluminum alloy can't bear too high temperature. Its melting point is 500-800 ℃.

4. Different surface treatments

Stainless steel surface treatment includes surface bright treatment, surface whitening treatment and surface coloring treatment; Aluminum alloy treatment includes electroplating, spraying, anodizing, etc.

5. Different industrial applications

Stainless steel has heat resistance, oxidation resistance, good formability and good weldability. It can be used as ultra-high strength material in nuclear industry, aviation and aerospace industry; Aluminum alloys are used for processing, and different series of aluminum alloys have different industrial applications, such as chemical products, food industrial devices and storage containers, printed boards, nameplates, reflective appliances, aerospace structural parts, etc.

How much is the price difference between aluminum alloy and stainless steel

We know that the price of stainless steel is higher than that of aluminum alloy, but there are many kinds of stainless steel, so the price difference depends on the brand. 304 stainless steel is more expensive, and 201 stainless steel is much cheaper. The prices of different series of aluminum alloys are also different, and the price difference is not large when the weight is the same.

Therefore, whether to use aluminum alloy or stainless steel mainly depends on where the product is used and what characteristics are required.

7075 product features:

1. high strength heat treatable alloy.

2. good mechanical performance.

3. good usability.

4. easy to process and good wear resistance.

5. T7351 status enhances corrosion fracture resistance

6. high strength materials for high pressure structural parts.

Generally, 7075 materials are added with a small amount of copper, chromium and other alloys, among which A7075 aluminum alloy is particularly top-grade,

Known as the best aluminum alloy products, high strength, far better than any mild steel. This alloy has good mechanical properties and anodic reaction.

Representative applications include aerospace, mold processing, mechanical equipment, tooling and fixtures,

It is especially used for manufacturing aircraft structures and other high stress structures requiring high strength and strong corrosion resistance.

Many friends don't know the difference between 7050，7055，7075. Let's talk about these three materials today.

7050 aluminum alloy is based on 7075 aluminum alloy. The content of Zn, Cu and cu/mg ratio are increased to increase the strength. Zr is used instead of Cr to overcome the problem of quenching sensitivity and inhibit recrystallization. It has high strength, fracture toughness and stress corrosion resistance.

7055 aluminum alloy is a new type of aluminum alloy developed by increasing the content of Zn and Cu and reducing the content of Fe and Si impurities on the basis of 7050. 7055 aluminum alloy has higher strength and stronger fracture toughness than 7050 aluminum alloy.

Select the required materials according to the characteristics of the product.
