Exchangers

Thermal Exchangers reduce the overall heat generated from weapon attacks by a fixed percentage. Unlike Heat Sink components, Thermal Exchangers are not impacted by the surrounding environment.

Heat Exchanger Efficiency

Generally speaking (in 6 out of the 9 biomes), the equivalent weight of double heat sinks are more efficient cooling per ton than heat exchangers until the amount of heat generated becomes greater than 120 at which point it's more efficient to fit the exchangers. As the tonnage and effectiveness of exchangers scales linearly this is true regardless of what type of exchanger you have (e.g. a 'mech producing 110 heat will get more value out of 3 double heat sinks than it will fitting an Exchanger +).

The table below lists the amount of heat in each biome you need to be generating in a 'mech in order for exchangers to be worth fitting. Depending on how much space you have available, in colder biomes (especially Polar) where heat sinks become even more efficient it might even be worth removing the exchangers from your 'mechs as you get a lot more bang for you buck.
