What is Spot Cooling?

November 18, 2019

Spot cooling provides temperature stability for sensitive electrical components. It enables temperature control of the individual components in a larger system or subsystem. Examples of spot cooling solutions include using active or passive cooling solutions to selectively cool an individual electronic component within a larger electronic assembly, or cooling a laser within a subsystem such as a TOSA (transmit optical subassembly).

In spot cooling, heat is efficiently dissipated from a device to control the temperature in a specific area or piece of equipment. This approach is commonly used in technology such as grid boxes and transformers. When the cooling method being used doesn’t require moving parts that generate noise or vibrations, it can also cool hi-tech fab or analysis equipment. Thermoelectric coolers (TECs) can be used in any of these applications to selectively cool the most sensitive components in a system.

Benefits of Spot Cooling for Telecom Applications

Often, thermoelectric coolers (TECs) are used for laser package spot cooling. By providing tight temperature control, TECs help solve common design challenges with embedded electronics in large network hardware or systems. To improve performance and reliability in spot cooling applications, TECs need to offer high heat pumping density and low power consumption. This enables excellent temperature control while saving on total costs within the laser package.

Phononic in Spot Cooling Applications

Effective cooling is essential to keep industrial equipment running at peak performance. Temperature control can be the weak link that forces designers to cater to it, impacting overall system performance. Phononic TECs deliver up to 30% lower power consumption and 60% higher heat pumping density as compared to alternatives. Additionally, they can easily provide heating instead of cooling if the equipment calls for it.

Phononic can help ensure high performance for your spot cooling application. With a Phononic TEC, you’re free to design the right thermal system for the rest of your circuitry. As a result, you’ll gain better control over your equipment without driving up cost or sacrificing performance.
