The field of electronics cooling has routinely encountered the high heat flux removal that cannot be handled by air cooling systems. The design and application of liquid cooled cold plates is an important aspect of being able to provide cooling for these high heat flux technologies. The intent of this book is to provide the reader with the approach to designing and implementing liquid cold plates. The book will describe the methods to designing liquid cold plates. The fundamental theory behind the heat transfer and fluid mechanics occurring in the cold plates is presented. A state of art review of cold plate developments and industrial practices is included to familiarize the reader with the possible alternatives. One of the highlights of the book is the inclusion of a detailed insight into manufacturing techniques for producing conventional and custom-made liquid cold plates. Some of the common issues and complexities related to manufacturing these cold plates are also presented as case studies. Finally, a few examples of utilizing liquid cold plates are provided. The book is written by a team of three recognized leaders in the field of electronics cooling technology. Cliff Hayner compiled his lifetime industrial experience on designing and manufacturing the cold plates before his sad demise during the production of the book. He provided the manufacturing insight that is rarely discussed in cold plate design literature. Mark Steinke is an accomplished researcher working at IBM, Research Triangle Park, NC. Satish Kandlikar, a professor at Rochester Institute of Technology, has been engaged in advanced cooling system research for over thirty years. The book presents a unique combination of the three complimentary viewpoints in guiding the reader through the entire design and manufacturing process. The book is also intended to serve as a textbook for graduate level courses and special workshops for cold plate design.
