| Sizing a Heat Exchanger for Cold Plate Applications |
In many liquid cooling loops, the heat that is picked up by a cold plate is rejected to the ambient air via a heat exchanger. Since the components are part of a system, it is important to select them together to ensure proper component sizing for your application. So how do you select the optimal heat exchanger for the complete system? It is easier than you might think, since the equations needed to determine the right cold plate and heat exchanger combination reduce to a very simple format... |

| Aluminum Corrosion Resistance for Cold Plates and Plate-Fin Heat Exchangers |
Aluminum cold plates and plate-fin heat exchangers are commonly used for liquid cooling in military and aerospace applications because of their light weight and high performance. There are many factors to consider when designing these cold plates and heat exchangers: thermal performance, size, fluid pressure drop, weight, burst pressure, and corrosion resistance. This article will address the corrosion resistance considerations in designing, building, and operating aluminum cold plates and plate-fin heat exchangers.

| Cold Plate Manufacturing Cost Drivers |
Cold plate prices can vary quite a bit; understanding why can help you cut costs and still obtain the performance you need to properly cool your application. The two biggest cost drivers in cold plate manufacturing are thermal performance requirements and annual demand, which generally thermal engineers have little or no control over. However, you can reduce costs by understanding how particular specifications can affect the cost of a cold plate. |

| Assessing the Quality of a Tubed Cold Plate |
As many applications move from air cooling to liquid cooling, tubed cold plates are often the technology of choice. What are the significant criteria for selecting a high quality tubed cold plate? Can you tell which cold plate is likely to have the best performance or be the most reliable?

| Designing Custom Cold Plates |
Liquid-cooled cold plates offer superior cooling for high power electronic devices, and can be purchased as standard products or can be custom designed. A custom cold plate is needed when there is a special shape or interface requirement or an extreme performance requirement. Understanding cold plate technologies, thermal specifications, and the steps involved in the design process will help to optimize the custom cold plate design so it provides the best value possible. |
