For high power density applications, such as lasers, servers, photovoltaic energy, medical equipment, and military equipment, water-cooled panels are the only choice due to the demanding temperature requirements. Because water-cooled panels are generally of high value, it is necessary to do some simulation analysis before sample production. FloEFD is very suitable for water-cooled simulation, using PROE's model to directly delineate the mesh, and then solve the results can be obtained, and modification and re-calculation is also very easy.

Results Explanation:
According to the simulation results, this design can satisfy the requirements of temperature rise and pressure drop. In addition, water-cooled plate design and process are very closely integrated, so understanding the process of different water-cooled plates is necessary as a prerequisite for the design of water-cooled plates.
Watercooling process:
Currently, there are several mainstream watercooling processes: copper bending and embedded in the base plate, base plate machining and welding of runners (including the design of fins in the runners), and the complex combination of piping type.
The base plate machined runner according to the different welding methods are divided into vacuum brazing, stir friction welding and other processes. The fins in the runners can also be divided into many kinds of processes, such as profiles, shovel teeth, welding, twisted pieces and so on.
Friction Stir Welding
Low Temperature Brazing of Buried Copper Tubes
Deep Hole Drilling of Water Cooling Plates
Therefore, we need to compare and evaluate the different programs according to the cost and design requirements at the early stage of the design, and then choose the optimal process for production. optimal process to produce.
The water cooled plate usually requires an external water cooler to be used.
