Tube-pressed liquid cold plates eliminate the need for integrally milled complex flow channels, as well as high-precision welding equipment and consumables such as brazing materials and shielding gas required for brazing or friction stir welding (FSW).
The production process consists of only four steps: grooving the base plate → cutting and bending copper/aluminum/stainless steel tubes → mechanical pressing-in or hydraulic/mechanical expansion jointing → flaring tube ports or welding connectors. This solution features low equipment investment, high yield rate and short single-piece processing cycle.
Compared with cold plates manufactured via integral milling plus FSW or brazing processes, tube-pressed cold plates normally cut costs by 30%–50%. They deliver outstanding cost competitiveness for price-sensitive applications including vehicle auxiliary components, industrial inverters and communication base stations.
