8.2.1. Passive Cooling

Try these first

1. 1.

   What is passive cooling?

   Hint

   Think about how heat can escape without devices needing power.

2. 2.

   Name a common material used for heat sinks.

   Hint

   Consider which materials are good at conducting heat.

3. 3.

   What is the main principle of passive cooling?

   • Using fans to cool
   • Natural heat dissipation
   • Using liquid cooling

   Hint

   Think about how heat can leave a device without being forced.

4. 4.

   True or False: Thermal pads are used to fill gaps between components and heat sinks.

   • True
   • False

   Hint

   Consider the effect of gaps between surfaces.

5. 5.

   Design a passive cooling system for an LED light that generates heat. Discuss your material choices and layout.

   Hint

   Consider the heat output of the LED and how it can effectively be dissipated.

6. 6.

   Evaluate a scenario where passive cooling fails. What are the implications for the system, and suggest alternatives.

   Hint

   Think about systems that might produce excessive heat.
