Heatsinks: Purpose and Design

Today’s computers continue to become faster and faster, but that speed coupled with the millions of calculations done in the blink of an eye generate heat that can threaten to destroy the processor itself. Heatsinksprevent this from happening by dissipating the heat as it is produced. These are necessary for all modern CPUs. Custom heatsinks offer solutions to the problem of heat on your own processors used for various applications. Custom heatsinks can be made from different metals, such as copper or zinc alloys, and can vary in size according to the needs of the specific processor. The addition of fins or metal slices on a custom heatsink increases the surface area of the heatsink, allowing for more efficient heat loss and dispersion. The addition of a fan can help further with the issue of overheating; those with a fan are considered active heatsinks, while those without are passive heatsinks. 

A heatsink manufacturer can work with you to design the perfect heatsink to keep your processor cool. You’ll need to work with the manufacturer to determine appropriate mounting style and heatsink material (which particular metal alloy is the best fit). The fins style can be varied as well. Don’t forget to work with the manufacturer to determine appropriate thermal resistance and well as the length, width, and height of your custom heatsinks.

Extruded heatsinks are most commonly used. To create these, the appropriate metal alloy is extruded through a steel die into the appropriate shape. Typically extruded heatsinks are initially very long “sticks” that are stretched and hardened before being cut into the final length prior to final secondary fabrication “touches.” 

If you are in need of custom heatsinks, contact a heatsink manufacturer to design the appropriate heatsink for your thermal management needs.

How Your Heatsink can be Customized

In need of custom heatsinks for temperature management? All CPUs need heatsinks to prevent them from overheating. This is done by increasing the surface area of the heatsink through various shapes and designs to allow for greater heat loss to the air (or water, depending on your application). The proper heatsink can reduce or entirely eliminate the need for a fan in your application.

Heatsinks may be made from different metals or metal alloys depending on the nature of your temperature management needs. These options typically include copper, nickel, or aluminum by themselves or as alloys. Each of these metals and their alloys has different properties which will help determine which is right for your application.

Heatsinks may or may have have fins to further increase surface area to promote heat loss. The possible designs for these fins is infinite. A heatsink with a pin fin, for example, fas the option of cylindrical, elliptical, or square pins. Those pins may also be straight or flared, again depending on your application. Many other types of fins are possible and available for manufacture.

Heatsinks may be treated with a surface treatment or different finish option as well. Work with your custom heatsink manufacturer to determine which option and specific finish or treatment is right for your application.
Custom heatsinks need to be mounted to complete the job they are needed to do. There are a number of different options for mounting your heatsink; Smartclip and socket clip are two such options.

When choosing a custom heatsink manufacturer, consider the total cost, time to completion, available surface treatment/finish options, packaging options, and, of course, options available for your custom heatsinks. Some manufacturers even have online tools to design your heatsink.

Custom Heatsinks for Optimal Results

If your business requires using a heatsink, you know how critical it is to find the right company to provide you with reliable merchandise, on time, and with globally competitive pricing. But what if you cannot use a heatsink that is readily available, but require something customized? Here are a few hints to help you find the right manufacturer.

Since you already have determined that a stock variety of heat sink will not work, have you figured out exactly what you need? Finding a company that has a staff of design engineers is critical, because even if you think you know what your requirements are, there might be a key factor missing in your design. It is always better to find that out before you commit too many of your hard earned dollars to squander on something that will not do exactly what you want. Not to mention the time, effort and energy you will have lost. Production time will be lost as well, and if your bottom line is time and date stamped, better avoid those costly delays.

Any company that you are considering should offer a complete thermal analysis for you, and offer a wide variety of materials to choose from. Some applications do best with aluminum, while others use copper. A good manufacturer can explain the pros and cons for each, show the costs for both, as well as delivery time. Information that will be critical for you when it is time to make a decision.

If you are located in the Livermore CA area or the San Francisco Bay area, you are lucky because there are companies that fit every part of this bill. And since these companies also deliver their products to a global market, location is not as important as it used to be.

Don't let what is on the market now in heatsinks stunt the creativity of your design team. Find a heatsink manufacturers who will customize the perfect solution for you, and go to the head of the line in manufacturing using a custom heatsink.

Cooling Sources in Electronics

What are Heat Sinks? In electronic devices, heat sinks are heat exchangers that are placed in different electronics and computers. To keep the whole device cool is the only function of a heat sink. There is a wide range of heat sinks, including forced or natural air cooling heat sinks and water coolers.

Active and passive are the two varieties of heat sinks. Heatsinks are made keeping in mind the heat a device produces. This heat needs to be absorbed to keep the device and its systems cool and functional. An aluminum extruded heat sink is the most common and most cost-effective means of providing the necessary cooling mechanism in an electronic device. 

Heatsinks are also provided with custom designs and features as effective cooling sources for different electronics. Some of the heat sink types are: 

• Skived fin heat sinks

• Folded fin heat sinks

• Bonded fin heat sinks

• Die cast heat sinks

• Stamped fin heat sinks

The CPU Cooler and its Function

In a CPU, the cooling system is of immense significance. CPU coolers are designed to dissipate the heat produced by different components working constantly in the unit. This type of air flow helps to moderate the temperature in any electronic device that produces excessive heat.

Failure of your CPU cooler can result in a problem like permanent damage of the device. Therefore, it is extremely important to have a close look at the cooling sources of any device to monitor whether or not they are working properly.

Fans of various sizes are placed in large computers to remove heat. This placement of exhaust fans in computers varies from model to model. Parallel and series installations of fans as cooling means in CPUs are the most common setups. Moreover, heatsinks are the most commonly used cooling sources that contain fins to offer the maximum cooling surface area to make contact with the air. 

There are many kinds CPU cooling sources, which include: 

• Active cooling sources

• Passive cooling sources

• Water and heat pipe cooling sources

• Exotic cooling sources

Liquid Cooling vs Heat Sink

Liquid cooling systems involve coolant-filled tubes, radiators and water blocks to keep the computer cool during excessive work. This setup sometimes includes a fan to help move around the water. However, in most computers, a heat sink is used to draw heat from the processing units. 

In some cases, heat sinks have proven inefficient in cooling computers. A device that produces excessive heat usually contains a liquid cooling system. This is mainly because water is an extremely efficient thermal conductor. Moreover, water can absorb more heat than heat sinks. In more expensive and advanced CPUs, the quality of the cooling source cannot be compromised. Therefore, the devices contain the most efficient cooling systems to make sure that heat produced in the processing units is being removed properly and efficiently. 

The effectiveness of liquid cooling technology, therefore, is preferred in modern computers and electronics. Liquid cooling means offer advantages, such as: 

• Efficient cooling boost

• Reliable for bigger, more advanced machines

• Preferable over traditional cooling sources
