Vacuum Brazed Cold Plates

Liquid cooling has certain limitations on its ability to cool effectively, due to tube-bending limitations. These limitations can be easily overcome by custom designed aluminum or copper cold plates. The most common method employed to generate the cooling path is through the use of folded fins, stakes of carefully machined thin fins, or precision die forged parts.

 

SNS Cooling Technology has significant technical know-how and design expertise to create leak-free plates. We highly recommend involving SNS designers during the design stage to benefit from years of design experience. This will help design a cost-effective solution to your crucial cooling requirements and a hassle-free end-product. Every custom cold plate is different in design, but the design process and fundamentals of design is the same. Our engineering team use advanced thermal analysis software to model your heat loads and create a cold plate design that meets or exceeds your thermal and pressure drop performance requirements. After the design stage, your custom cold plates are manufactured and pressure-tested to meet your requirements, and stamped “T” after testing. We can comply with lot traceability & can provide ultrasonic inspection record upon request.

 

For ease of operation & reliability of joints for a longer life of threaded joints, we recommend using parallel thread connections rather than taper thread connections for vacuum brazed cold plates.
