Liquid cooling is just like forced convection in that fluid is forced through the system by an external source like a pump. While most applications use water or water/glycol mixtures as the primary fluids, any liquid can be used, including liquid refrigerants, fluorocarbons, gasoline, hydraulic fluid, or oil to name a few. Liquids are more efficient then forced air because the specific heat of liquid is higher than the specific heat of air and just like forced air cooling, liquid cooling is most efficient if the fluid is turbulent. However, turbulent flow puts a strain on the pump.
Standard Liquid Cold Plates
In addition to the endless opportunities of custom liquid cold plates. Wakefield-Vette offers a large family of standard off the shelf product.
Exposed Tube
Wakefield- Vette’s exposed tube liquid cold plates ensure minimum thermal resistance between the power device and the cold plate by placing the coolant tube in direct contact with the power device’s base. Direct contact reduces the number of thermal interfaces between device and fluid thus increasing performance for the application.
Key Characteristics
Economical extruded base with continuous copper tube
Continuous copper tube reduces leakage
Tube and base bonded by highly conductive epoxy
Numerous flow paths for various location of heat sources
Exposed Tube Standards

| 120460 | 6- Pass Coldplate | 24.00 |
Full Buried Tube
Wakefield- Vette’s fully buried tube liquid cold plates have the ability to cool both sides of the cold plate because of it’s positioning within the base plate. Another key feature of the fully buried tube is that it is not exposed to the outside environment. Some engineers prefer the epoxy layer above the tube to protect the tube from leakage.

Rolled Tube (180 Series)
Wakefield- Vette’s rolled tube liquid cold plates are usually the most cost effective liquid cold plate solutions. The key attribute for this line of standard cold plates is that the liquid flow is contained in a continuous tube. These standards cold plates come in 2 and 4 pass versions.
