Introduction

• Fins are a useful way to increase heat transfer
  with minimal increase in volume
• There is evidence suggesting that even dinosaurs
  used fins for heat transfer
• Fins transfer heat either through free or forced
  convection
• A transformer found outside a church building
  with fins on it was modeled for this project

Objectives

• This project seeks to find out how much larger a
  transformer would have to be without fins to
  transfer the same amount of heat flux
• Modeled using free convection of air
