Kurzbeschreibung des Verlags

Spare cooling capacity does not guarantee cool servers. What matters is whether heat can move reliably from the rack to the final heat sink.

High rack loads, uneven airflow, restrictive liquid circuits and unstable controls can leave engineers facing hot spots even when equipment ratings appear adequate. Solving the problem requires a clear view of the complete thermal path, including the assumptions, measurements and operating limits at every interface.

This practical engineering handbook connects cooling design with commissioning and field diagnosis. Across fifteen chapters, it develops the principles and calculations behind air, liquid and hybrid systems, then shows how to use those relationships to evaluate performance, investigate faults and understand engineering tradeoffs. Worked examples make units and assumptions explicit, so the reasoning behind a result remains visible.

Use this handbook to:

- Define defensible thermal loads by separating measured demand, rack density, future growth and the capacity reserved for redundancy.- Diagnose airflow problems by examining containment, bypass, recirculation, pressure losses and the conditions at individual equipment inlets.- Evaluate direct-to-chip and immersion systems through coolant properties, cold plates, distribution units, facility interfaces and residual air loads.- Connect pumps, fans, piping and heat exchangers with plant temperatures, economization and heat-rejection limits under changing operating conditions.- Assess sensors, control sequences, failure response and commissioning evidence to understand how cooling service behaves during normal and degraded operation.- Compare energy, water and heat-recovery choices while preserving thermal margins, and use measurements to test possible causes of poor performance.

>For new designs, the chapters help connect the load basis to architecture and operating requirements. For existing facilities, the same principles help organize temperature, flow, pressure and power evidence into a reasoned investigation. The emphasis throughout is on physical interpretation, explicit boundaries and verification.

Written for mechanical and facility engineers, data-center designers and operators, commissioning professionals, controls specialists and upper-level engineering students, the book assumes algebra and basic thermodynamics and fluid mechanics. It supports project-specific engineering judgment and must be used alongside equipment requirements and approved procedures.
