© Oxford University Press 2011 IP1.7.3 Energy transfers 1 Look at this radiator. Can you think of two elements in its design that help it transfer thermal energy?

© Oxford University Press 2011 IP1.7.3 Energy transfers 1 Can you think of a way the transfer of thermal energy could be increased still further? Think about the colour of the radiator.

© Oxford University Press 2011 IP1.7.3 Energy transfers 1 What method does this heat sink use to maximise thermal energy transfer?

© Oxford University Press 2011 IP1.7.3 Energy transfers 1 It uses metal, which is a good thermal conductor and has a large surface area. Both these things help to transfer the energy away from the video card.

© Oxford University Press 2011 IP1.7.3 Energy transfers 1 Look at this heat sink. How is thermal energy transfer being maximised even further?
