Heat Transfer: Conduction, Convection & Radiation Guide with Worked Examples

Heat transfer is the study of how thermal energy moves by conduction, convection and radiation. These guides pair fundamentals with worked practice problems, lab experiments and design examples such as heat sinks and battery thermal management.

Frequently asked questions

What are the three modes of heat transfer?

The three modes are conduction through solids or stationary fluids, convection through moving fluids, and radiation through electromagnetic waves.

What is forced convection?

Forced convection is heat transfer between a solid surface and a fluid moving because of an external mechanism such as a pump, fan or stirrer, rather than buoyancy.

What does a heat sink do?

A heat sink is a passive heat exchanger that moves heat from a device to a fluid such as air or liquid coolant, helping keep the component’s temperature in range.

Where can I practice heat transfer problems?

The heat transfer practice problems article includes 20 original problems with worked solutions covering conduction, convection, radiation, energy balances and heat generation.
