Weekly Progress
This week I search about heat sink. In electronic systems, a heat sink is a passive component
that cools a device by dissipating heat into the surrounding air. Heat sinks are used to cool
electronic components such as high-power semiconductor devices, and optoelectronic devices
such as higher-power lasers and light emitting diodes (LEDs). Heat sinks are heat exchangers such
as those used in refrigeration and air conditioning systems, or the radiator in an automobile. The
most heat sink materials are aluminum alloys and Copper with aluminum that can heat out of it
better copper but copper can conductive heat better aluminum.
Figure 1. Figure 2.
Engineering Analysis
Strong Point
- Copper is good conductivity of heat.
Week Point
- Copper is low for heat out of it.
Next Week Job
- I will think about design circuit control temperature for our project.
