The water-cooled (liquid-cooled) cooling system uses a pump to circulate and dissipate the cooling liquid in the heat pipe. The heat absorption part on the radiator (called the heat absorption box in the liquid cooling system) is used to absorb heat from the new energy battery power pack, 5G communication equipment, IGBT controller, UPS and energy storage system, large photovoltaic inverter heat dissipation, SVG/SVC heat dissipation. The heat absorbed by the endothermic part is discharged to the outside through a radiator designed on the back of the pyrogen.

In the fields of power electronic control, conversion, drive, signal transmission and new energy (new energy vehicle power battery heat dissipation, UPS and energy storage system heat dissipation, large server heat dissipation, large photovoltaic inverter heat dissipation, SVG/SVC heat dissipation, etc.), in order to pursue high efficiency, low noise and low temperature operation, and limited by space, The problem of heat dissipation has become the biggest limit of the ideal product development, and the liquid cooling heat dissipation technology has become the preferred thermal management method.

FrictionStir Welding liquid cooling features:

The heat generated by the friction between the high-speed rotating stirring head and the workpiece is used to make the local plasticization of the Korean material.

Liquid cooling advantages of friction stir welding:

The weld has good mechanical properties, and friction welding is a kind of solid-phase connection method. The welding temperature is low, and the weld metal only reaches the plastic state without melting, maintaining the metallurgical properties of the base metal, and there will not be a large range of thermoplastic deformation process and welding defects in the weld during the melting process.

Low cost, high efficiency, is through the friction and agitation between the stirring head and the weldment, then step to realize the welding of the whole weld, and in the welding process, do not need to add other welding materials, such as electrode, wire, flux and protective gas.

Welding process is safe, no pollution, no smoke, no radiation.

Friction stir welding liquid cooling disadvantages:

High loss of welding head.

The welding process requires a specific welding head fixture and the workpiece should have a good support or liner (fixture).

Manufacturing process capability:

Maximum welding thickness: 2-25mm.

Processing size: 1350*850*300mm.

Welding capacity: 1000*600*25mm.
