Compared to wind cooling device, liquid cooling plate can bring more heat efficiently, meanwhile liquid cooling plate usually need more cost.
There are many types of liquid cooling plate, such as friction stir welded (FSW) aluminum cooling plate, press-lock tubed cooling plate, vacuum brazing cooling plate, etc.
How to choose a liquid cooling plate. First, we should know the feature of each.
FSW liquid cooling plate
FSW liquid cooling plate is welded by two aluminum plate through mechanical press and friction heat.
Advantage: high reliability without leak risk due to common welding defects.
Disadvantage: High cost and high requirement to operators.
Vacuum brazing cooling plate
Vacuum brazing water cooling plate is made by vacuum brazing of two aluminum plates milled with same liquid channel.
Material: Aluminum
Advantage: Lower pressure drop; more heat transfer area; Cost saving during mass production.
Tube pressed cooling plate
Tubed water/liquid cooling plate consist of aluminum base plate and bended tubes.
Material:
- Base plate, aluminum, copper;
- Tube, copper, stainless steel, copper-nickel alloy.
Advantage:
- Tooling cost is lower, usually only tube bending tool is necessary.
- Liquid system can be with high internal pressure.
- Both two plate can be used to transfer heat from two heat source through mill each surface.
- Easy to be designed to meet mounting dimension of heat source.
