GD Rectifiers' water cooled heatsinks are highly efficient and provide reliable thermal performance for high power modules. Water cooled heatsinks are a popular choice for engineers today, because of their many advantages over using air cooled heatsinks.


Advantages of using Water Cooled Heatsinks

- Water has higher thermal conductivity than air

- Water has a higher specific heat capacity

- Water can move heat faster than air

- Water can absorb heat before it starts to feel hot

GD Rectifiers' water cooled heatsinks are used in a wide range of applications: transportation, lasers, medical equipment, electronic equipment for defense and radio transmitters.
