Client: GE

Project Objectives:
Design a cooling system for the charge port that

• Prevents the charging paddle from getting hot enough to burn the user on removal
• Allows the charge port to be located anywhere within the body of the vehicle

Achievements:
Since the port and cooling system must be modular and compact, a liquid cooling system was eliminated from consideration. Using baffles to optimize heat transfer from the paddle, small air channels around the paddle, and external fins, a system utilizing an 80 mm fan was demonstrated to provide sufficient airflow to cool the charger.

Client: Rockford

Project Objectives:
Find a thermal design for a multi-kW audio amplifier unit that

• Maintains individual amplifier packages within operating limits
• Looks different from other existing units in the market
• Can survive inside the trunk of a small car

Achievements:
An extrudable annular heat sink design was found that cooled the amplifier packages, in conjunction with an axial exhaust fan. Furthermore, this design allowed amplifier boards to be mounted individually in low-end systems or together into a high-end system.
