When it comes to electronic systems,aluminum heat sink act as heat exchangers that help to cool a device by transferring heat on to the medium surrounding it. They are also used in computers to cool the CPU, also known as the Central processing unit. This technology used is LEDs, also known as Light emitting diodes. Normally, they are used for any device with an insufficient capability of dissipating heat.

Heat sinks are created to maximize the surface area of the device and increase the contact of the cooling medium that surrounds it. It is used in many devices nowadays and works excellently with LEDs compared to other techniques. Among the different types, Pin Fin sinks are gaining a lot of popularity among people.

A Pin Fin heat sink is a normal type, but it differs from others as it consists of pins that are extended from its base. These pins are in various shapes including elliptical, cylindrical and square shapes. It is the most common type available in the market nowadays. Generally, a heat sink should work better when it has a large surface area, but this is not true in all the cases. This sink works on the concept of packing as much surface area as possible into any particular volume.

One can also find straight fin heat sinks, but Pin Fin works better than them as the fluid flows along the pins axially instead of flowing tangentially. The main advantage is that they perform in a better manner when they are placed in a tilted position. When compared to others, they show a better performance as well. They are perfect for spotlights that are adjustable and they can also be used for shop lighting and downlighting.

Pin fin sinks are compact sinks, fabricated with a huge number of pins that are created to provide a lot of air. In addition, they are designed and structured geometrically in a highly effective manner. They excel when they dissipate the heat from electronic devices with a forced convection. The material used in any technique makes a huge difference and since these Pin fin sinks are manufactured with the best quality of Aluminum, the process is carried out effectively every step of the way.

Building a Solar Panel Frame – Materials, Tools and Workmanship

02.06.15 / Uncategorized / Author: / Comments Off
Tags: ,

When building a aluminum solar panel frame, it is important to consider a few factors that will make your solar panel last. Some of these include material, design and workmanship. These are equally important. Thus we will look into each of them in detail.

Wood, plastic and metal are some materials you can use to make your solar panel frame. If you are considering wood, plywood may be a good option. They are strong, reasonably priced and easy to work with. If you’re inclined towards using metal, aluminum is the best. Aluminum can withstand heavy loads and pressure when alloyed appropriately. Its strength approaches that of steel. Most importantly, it is light.

Among these 3 materials, aluminum is the longest lasting and can keep your solar generators in ship-shape for up to 30 years.

When designing your frame, you have to think about the material thickness and how you’ll make the joints. If you’re using wood, dovetail joints are the best, although it will certainly take you more time. An alternative to this is the miter joint. If you’re using aluminum, you have the option of welding, soldering or bolting the pieces together. Generally for a solar panel, any one of these methods will do since these panels will not be subjected to very high loads or stresses.

Finally, your solar panel frame is likely to give way before its time if the workmanship is bad. Here are a few pointers to help you make sure this never happens to you:

1. Make sure you are working on a solid, level surface.

2. Use table clamps (or other types of clamps) to help you hold your material properly as you are working on it.

3. Use simple tools like the carpenter square to help you get your corners right.

When you consider the materials, tools and workmanship that goes into your solar panel frame, you are more likely to build a solar panel frame that can last you a long time.

Tags: ,

Recently, many hobbyists want to build their own solar panels at home. Catching on this trend, retailers have also been selling tools and materials so these hobbyists can get what they want. Before long components such as solar cells, tabbing wires and solar panel frames are readily available in the market.

There are also solar guidebooks that teach beginners and advanced hobbyists alike on how to make their own home solar power generators. With these materials, they are able to refer to proven blueprints that will eventually lead them to build their own complete set of solar panels.

In order to choose a good guidebook, you have to make sure that it is filled with photos and illustrations on how to make each part of the aluminum solar panel frame. Better products will also include videos so there is no way you will be lost while in the midst of your PV panel project. With the help of schematics, drawings and step-by-step instructions, you can soon be enjoying solar electricity at the comfort of your home.

It takes very little to build a PV panel. However each PV panel is not cheap either. There are claims that you can make your own solar panels (that can power up your entire house) for a few hundred dollars. Unfortunately such claims are not credible. With this budget, you can only build a small solar panel that can run a battery charger or your desktop.

Realistically, each PV panel you build will cost a little more than $100. Those under $100 are basic and their PV panel frames are made of wood. Compared to aluminum frames, wooden frames do not last as long. Also, these budget DIY solar panels are made using solar cells with average or lower-than-average yield. Therefore even though it is possible to make a PV panel under $100, it is not advisable to do so. Having said this, it is a good idea to build cheap PV panels for the sake of education. Mistakes will not be as costly in such cases.

For a PV panel to last as long as 20 or more years, they almost always have to be made of aluminum. Aluminum angles are readily available in hardware stores. And if you do not want to cut them yourself, you can order extruded aluminum brackets make specially for building PV panels.

When you choose your solar cells, make sure you check its type and quality. You will not go wrong if you insist on a model that gives you the most electricity for the least amount of money. More importantly, you have to make sure these solar panels are made by a manufacturer who can give you the support you need.

What is Aluminum Extrusion?

26.05.15 / aluminum extrusion manufacturers / Author: / Comments Off
Tags: , ,

Considering its weight and cost, aluminum is an excellent thermal conductor. This makes aluminum well-suited for applications that require key exchanges. As an added benefit, extrusion is a well-suited metal forming process to help reduce shapes that will optimize the thermal conduction properties of aluminum.

Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses. From aluminum extrusion manufacturers the extrusion process makes the most of aluminum鈥檚 unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals.

The process of aluminum extrusion consists of the following steps:

After designing and creating the shape of the die, a cylindrical billet of aluminum alloy is heated to 800掳F-925掳F.

The aluminum billet is then transferred to a loader, where a lubricant is added to prevent it from sticking to the extrusion machine, the ram or the handle.

Substantial pressure is applied to a dummy block using a ram, which pushes the aluminum billet into the container, forcing it through the die.

To avoid the formation of oxides, nitrogen in liquid or gaseous form is introduced and allowed to flow through the sections of the die. This creates an inert atmosphere and increases the life of the die.

The extruded part passes onto a run-out table as an elongated piece that is now the same shape as the die opening. It is then pulled to the cooling table where fans cool the newly created aluminum extrusion.

When the cooling is completed, the extruded aluminum is moved to a stretcher, for straightening and work hardening.

The hardened extrusions are brought to the saw table and cut according to the required lengths.

The final step is to treat the extrusions with heat in age ovens, which hardens the aluminum by speeding the aging process.

Additional complexities may be applied during this process to further customize the extruded parts. For example, to create hollow sections, pins or piercing mandrels are placed inside the die. After the extrusion process, a variety of options are available to adjust the colour, texture and brightness of the aluminum鈥檚 finish. This may include aluminum anodizing or painting.

Today, aluminum extrusion is used for a wide range of purposes, including components of the International Space Station. These diverse applications are possible due to the advantageous attributes of aluminum, from its particular blend of strength and ductility to its conductivity, its non-magnetic properties and its ability to be recycled repeatedly without loss of integrity. All of these capabilities make aluminum extrusion a viable and adaptable solution for an growing number of manufacturing needs.

The construction of a solar panel framework, to consider several factors, will make important solar panels on your. These include materials, design and workmanship. These are equally important. We would therefore be specific to each person.

Wood, plastic and metal are some materials you can use to make your solar panel frame. If you are considering wood, plywood may be a good option. They are strong, reasonably priced and easy to work with. If you’re inclined towards using metal, aluminum is the best. Aluminum can withstand heavy loads and pressure when alloyed appropriately. Its strength approaches that of steel. Most importantly, it is light.

Frankly, almost nobody seriously considers using plastic. But if you are one of those few who are adventurous enough, be sure to use thermosets rather than thermoplastics. Thermoplastics cannot stand high temperature. Thermosets can be brittle, so if you are living in an area where hails are common, you may need to reinforce your frame. An important reason why almost nobody favors plastic is because they are bad conductors of heat. With heat build up in your solar panel frame, your solar cells will not be working as efficiently as they are capable of.

Among these 3 materials, aluminum is the longest lasting and can keep your solar generators in ship-shape for up to 30 years.

When designing your frame, you have to think about the material thickness and how you’ll make the joints.

Mentioned “sheet metal processing”,and in the unity of thought,can you imagine a “tin man”.Now, the tin attack still exists,and can be so long,sheet metal processing has become an art form in the twenty-first century.

An artist may use a paint brush, a palette and an easel, a tin basher’s tools include a hammer, anvil, grinder, and welder, but the 21st century sheet metal fabrication relies on technology. It is a technology that uses the same tools, but in an automated fashion, to achieve the same results in less time, at a fraction of the cost, in much the same way that scanners and printers have automated an artistic world.

Nothing is ever made until someone has an idea. Expensive tooling costs invariably prevent any form of mass production until such time that prototypes have been manufactured, tested, and approved. Even in the technological sheet metal fabrication age, there will always be a need for some basic tin bashing before automation takes over. If size constraints and budgets are not an issue, tin bashers will further decline with the introduction of 3D printing.

There are those that will say that technology has taken the skill out of sheet metal fabrication. In fact, the opposite is true. A different skill set is required when applying technology to the process. Innovation is at the forefront of today’s sheet metal fabrication industry. Despite the increased use of plastics in manufacturing, sheet metal fabrication is still able to compete in the marketplace. It competes because of the innovation, the ability to do in seconds the same processes that would have taken a tin basher days to complete. Sheet metal fabrication was revolutionised with the arrival of CNC machinery and now is further enhanc

When it comes to sheet metal fabrication, it makes little odds whether one operates as a tin basher or as a fully automated jobbing shop – the principles remain the same. Automation and technology will only ever be as good as the individuals who program, set, and operate the machines. The ideas, the thought processes, and the implementation of new methods are no different between a tin basher and someone involved in the technological fabrication processes.

Show me someone who employs all the technology available in the industry, and I will show you someone who deep down, is, and always will be, a tin basher. And both are artists.This industry thrives in the 21st century, and it will continue to in the 22nd and beyond.
