Cold Plates

When air-cooled heat sinks cannot cope with too high power densities, liquid-cooled cold plates are the heat transfer solution of choice. With its broad range of cold plate technologies, AMS Technologies meets the most specific fluid compatibility and performance requirements. Friction stir welded (FSW) cold plates are suitable for glycol-water and very high cooling needs, while press-lock tubed types are ideal for tap or de-ionised water. For special applications, vacuum brazed cold plates, flat tube cold plates or pin fin types are available as well as models for low to medium power densities made of hot-rolled aluminium metal sheets. You can’t find a standard cold plate that ideally suits your needs? Get in touch with AMS Technologies for your customized cold plate solution!

We can support your project throughout the entire development process of a custom cold plate, from calculation and design to manufacture and test of the resulting solution. Early involvement of our specialists in the project is the key to successful thermal management of the system. We work closely together with your design team to find a high level of efficiency, good profitability and overall an optimal solution for every single project. Our specialists will support you at any time and provide input on all questions relating to thermal management on request. Contact AMS Technologies for high quality thermal management that meets your requirements.

Today, modern devices are becoming more and more compact, with the power density growing at the same time. As a result, the requirements for contact cooling of critical heat sources are increasing considerably in many applications like lasers, optoelectronics, power electronics, medical, drives, military or aerospace and many more. Cold plates are very well suited to meet these challenges – they can be operated both on an open cooling circuit (tap or process water) and on a closed cooling circuit which, for example, uses recirculating chillers to dissipate the waste heat to the ambient air.

Fluid Compatibility is Key

When selecting your cold plate technology, it is important that the wetted surfaces of the cold plate are compatible with the coolant used. Copper as a wetted path is well suited for water and most common coolants. Aluminium, on the other hand, offers very good cooling performance in combination with ethylene glycol and water solutions (EGW) as well as oils and other liquids, but is not suitable for use with untreated water. Cold plates with stainless steel wetted surfaces are recommended for use with deionized water or other corrosive fluids.

Limited Flow Rate

In the application, the flow rate of the cold plates cannot be increased too much, otherwise erosion may occur in the liquid channels due to the excessive flow velocity of the cooling medium. Therefore, manufacturers usually specify a maximum flow rate in the specifications. For connecting the cold plate with the cooling medium there are various connection options such as open tube ends, screw-on fittings, click-on quick-release fittings or threaded holes in the cold plate body.
