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.
Micro-channel copper skived heatsink + copper base
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.

Friction stir welding liquid cold plate
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.
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.

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.
