Skiving fin heat sink with thermal tube or pressed tube

Consist of skiving fin heat sink and tubed cooling plate.  It has all advantages from them.

Advantage of skiving fin heat sink

• There is usually no additional tool cost necessary.
• Compared with bonded fin heat sink, skiving process can get the fin and base plate as a whole part, without binder.  So skiving fin heat sink  is with higher thermal conductivity and more heat exchange area.
• Due to the uniform material of fin and base plate, skiving heat sink surface is easy to be treated by oxidation,  passivation, etc.
• Fin height dimension up to 350mm.  heat sink length  up to 1000mm.

Tubed 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.
