The tube cold plate consists of two key components, one is substrate , the other is a continuous copper or steel tube .There are generally three forms of combination between the bottom plate and the pipe, include buried pipe, welded pipe, double-sided clamp pipe. The Tubed Cold Plate is engineered as a cost effective and reliable solution for thermal management applications where liquid cooling of components is preferred over air.

ü Buried Pipe Tube Cold Plate

Most of them are aluminum substrate buried copper pipe. First, the aluminum substrate is milled with CNC, then use a stamping machine to press the bent copper tube onto the aluminum substrate, then perform brazing and welding, and then process it into a water-cooled plate.

Buried Tube Process divided into two types: Shallow buried Pipes Process and Deep Buried Pipes Process :

Shallow buried Pipes Process,Press the copper tube into the groove inside the aluminum substrate to deform, and then apply a flying cut on the surface.

Deep Buried Pipes Process, inserting copper pipes into deep grooves inside aluminum substrates, the filler is high thermal conductivity epoxy resin. When the temperature difference requirement of the cooled device is not high, it can be installed on both sides. As the thickness of the copper tube is not subjected to secondary processing, and there is filler protection, it can provide application safety.

ü Welded Pipe Tube Cold Plate

Suitable for the combination of copper substrate and copper tube, in order to reduce the thickness of the plate and achieve weight reduction.

ü Double-sided Clamp Pipe Tube Cold Plate

There is a tube between two substrates, which is a simple and cost-effective technology. The combination can be aluminum plate+aluminum tube/copper tube/SUS tube.

ü Good heat uniformity

Friction stir welding water-cooled plates have safer and more stable heat dissipation performance. Friction stir welding water-cooled plates have larger flow channels, further reducing thermal resistance. Especially in dealing with complex flow channels and certain flow channels with height differences, it has more flexibility.

ü High reliability of joints

There are no welding porosity defects, element burning damage, or thermal cracks in the weld seam. As a solid-state welding process, friction stir welding is a basically defect free connection method, ensuring high reliability without leakage.

ü High material strength
