Air Ionizers and Thermal Management – Two crucial aspects of electronics manufacturing

11 10 2011

An air ionizer is a small device which uses a high level of voltage to electronically charge air molecules. So, how are they used within the electronics manufacturing industry?

Air ionizers are most commonly used within air purifiers. The majority of commercial air purifiers that you would encounter today are designed to generate negative ions.

Negative ions (otherwise known as anions) are particles made up of one or more electrons, conferring a net negative charge to the particle.

Within the air purifier, the airborne particles are attracted to the electrode in an effect which has been compared by many to static electricity.

One of the most common mistakes that people make is confusing ionizers with ozone generators. This is understandable since both operate in similar ways within whatever appliance they are found in.

However, while ozone generators are optimised to attract an extra oxygen ion, ionizers use electrostatically charged plates to ultimately produce gas ions.

 

Thermal Management

One of the key aspects of electronics is controlling the heat which is generated by the construction of complex devices and circuitry.

The heat can sometimes cause devices to fail to function properly before they have been used at all.

Techniques for heat dissipation include the use of fans and heat sinks for air cooling, liquid cooling and computer cooling.

Heat sinks have become an essential part of modern electronic construction. They are used to reduce and control the temperature of items such as microprocessors through sophisticated heat dissipation techniques.

They are basically made up of a small metal structure which includes flat surfaces to ensure good thermal contact with the components that need to be cooled.

Within the electronics industry, they are used most frequently for the cooling of electronic devices. Complex circuitry and devices require protection from the extreme generation of heat, otherwise they cannot perform the tasks for which they were designed.
