What are heat exchangers?

All,

I have a 2000 Boxster S. I had the coolant pump go south and bolted on a new one, as well as a new serpentine belt. It still overheats. I have read some stuff on this site that wised me up to the possibility of debris from the disintegrated prop blades in the old water pump still being in the coolant channels, thus causing a clog. Someone suggested I pull the thermistor housing since the bits and pieces may have gathered there. They also suggested doing the same for the "heat exchangers". I have scoured my manual but cannot find any reference to a heat exchanger. Any thoughts on what else they may be called? Also, any advice on how to "burp" the coolant system to get air out, I understand that needs to be done as well. Thanks for any help you may provide.

Jim
