Heat sink technology keeps your devices functioning

You may interact with a heat sink on a daily basis and not even realize it. But what is a heat sink?

A heat sink is a device that disseminates heat from another object. In a heat sink, the energy released in the form of heat is transferred through an object and out into the surrounding environment. Heat sinks are commonly used in computers, cell phones, and other devices that need to stay cool to keep them functioning. If you are reading this post, chances are you are either holding a heat sink in your hand or looking across your desk at one. 

As technology advances and our devices decrease in size but increase in speed, this technology is especially important. 

 

Aluminum heat sink

To work effectively, a heat sink needs to be made out of a conductive material. The most common material used is metal. Although the material can vary, many devices utilize aluminum as their chosen material. Aluminum is a metal with high thermal conductivity, meaning it is incredibly effective at wicking away heat. 

 

Heat sink for LED Displays

Why do LED displays need a heat sink?

When the pixel pitch of an LED sign decreases, the energy relased by the bulbs, in the form of heat, increases. Because of this, using a heat sink is the most effective method for keeping the components of the sign cool, especially compared to the industry standard of using bulky and outdated fans. 

GDTech utilizes an aluminum heat sink in its premium LED signs. This technology allows for a greater sign resolution, resulting in clear and beautiful images that can tell the story of your business to every person driving by.
