FSW Cold Plates
Why use FSW liquid cooling plate?
Its flexible flow channel selection can give your thermal design more space to choose.
Choosing the right flow channel can optimize your thermal design. Vansim provides you with a reliable manufacturing option for your design.
FSW Cold Plates
Process introduction:
The cover plate and the bottom plate with the flow channel groove are processed separately, and the processed cover plate and the flow channel bottom plate are combined together. The cover plate and the bottom plate are welded into one along the flow channel contour line formed by the cover plate and the bottom plate by stir friction welding, and then processed into a liquid cooling plate after mechanical processing and surface treatment.

Liquid cold plate
Friction welding technology is widely used and practical in the field of liquid cooling, Enabling the Manufacture and Application of many water-cooling designs.
Vansim takes you to intuitively experience the application of friction welding technology on water cold plates.

Application Status:
Friction stir welding technology is a solid-phase connection technology. This welding method does not require solder or flux, so the friction welding liquid cold plate will not have the phenomenon of water channels being blocked by foreign matter such as solder. The friction stir welding weld can reach or approach the strength of the parent material, and the product reliability is high. The friction stir welding process can weld different grades of aluminum materials together, providing more design possibilities; the flow channel structure design is flexible, the heat dissipation performance is good, and the one-piece aluminum structure can be applied to a variety of surface treatment methods.
Vansim will use its many years of manufacturing experience of FSW apply for liquid cooling plate to provide you with more reference suggestions
FSW process applied to the data center servers water block
The friction stir welding strength of the water cooling block processed by friction welding is close to the strength of the parent material, with good airtightness and extremely low defect rate.
The material is unified, the thermal conductivity is better, the service life will not change significantly over time, and the reliability is very good.
According to different types of flow channel designs, combined with high-density copper shovel teeth, a microchannel water cooling head can be made.

FSW liquid cold plate used for fiber laser liquid cooling system
The multiple pump sources and beam combiners in the beam combining module of the fiber laser will generate a lot of heat during operation. The characteristics of the friction welding water cooling plate are that it can accept flexible flow channel design. The requirements for wide flow channel and large flow rate liquid cooling design are relatively limited by other water cooling plates, so the friction welding water cooling plate is widely used in laser liquid cooling.
The most important point to pay attention to in the processing of laser water cooling plate is the processing of fiber grooves. It must be ensured that there are no burrs or knife marks, otherwise it will affect the installation of the fiber and damage the fiber.

FSW liquid cooling plate used for battery cooling system
The lightweight requirements of the water cooling plate of the new energy storage battery pack use aluminum extrusion profiles to form a harmonica-tube flow channel design. Friction welding is used at both ends to ensure the sealing of the front and rear plugs. After welding the water nozzle, the inlet and outlet of the water pump are connected in parallel to complete the overall water cooling and heat dissipation cycle.
This type of profile flow channel water cooling plate has a simple processing process and uniform flow channel distribution, but the width of the profile mold has certain limitations. The overall width of the water cooling plate will be limited. It is necessary to use multiple groups of water cooling plates in parallel, which has cost advantages for the heat dissipation of a single group of battery modules used side by side.

FSW liquid cooling plate for Thermo Electric Cooler
The water cooling assembly of the liquid-cooled Semiconductor cooling module includes a heat absorbing bottom plate connected to the hot end of the semiconductor refrigeration chip and an upper cover covering the heat absorbing bottom plate, a water cooling cavity and a water inlet and a water outlet connected to the water cooling cavity are provided between the upper cover and the heat absorbing bottom plate;
Copper or aluminum water-cooled plates can use friction welding technology to complete flow channel processing. For the small volume requirements of cold plates in high-power semiconductor refrigeration modules, friction welding water-cooled plates are a good choice.

FSW process used for electronic control liquid cooling system
The electric control box of new energy vehicles has a liquid cooling cycle, which is usually completed by friction welding. The prototype of the electric control box cavity is generally produced by CNC machining. The batch processing needs to open a die-casting mold to reduce costs.
During the production and processing process, the balance rate of the entire processing line, the unstable data changes caused by the deformation of the blank surface and the side positioning reference surface, how to stably machine the holes and processing surfaces, and the customized fixtures for positioning processing are very critical.

FSW process used for High-power Power supply liquid cooling chamber
The circulating water cooling system for high-voltage shore power supply heat dissipation improves the heat dissipation effect of the equipment, reduces heat accumulation, and increases the service life of power components. It improves the stability of high-voltage shore power supply.
The high-power water-cooled chassis heat dissipation system has a cooling liquid flow channel built into the chassis cavity frame. The cooling liquid flow channel forms a liquid cooling cycle on the chassis bottom plate through friction welding, and the liquid cooling joint is connected to the external cooling liquid circulation system.
