Thermal Design Power (TDP), also known as thermal design point, is the maximum amount of heat that a computer component (like a CPU, GPU or system on a chip) can generate and that its cooling system is designed to dissipate during normal operation at a non-turbo clock rate (base frequency).
Cooling capacity is the measure of a cooling system's ability to remove heat. [1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity".
Liquid cooling is typically combined with air cooling, using liquid cooling for the hottest components, such as CPUs or GPUs, while retaining the simpler and cheaper air cooling for less demanding components. The IBM Aquasar system uses hot water cooling to achieve energy efficiency, the water being used to heat buildings as well. [40] [41]
The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
The overall cooling efficiency depends on how the air distribution system moves air through the equipment room, how the equipment moves air through the equipment frames, and how these airflows interact with one another. High heat-dissipation levels rely heavily on a seamless integration of equipment-cooling and room-cooling designs.
Fig.1 Schematic diagram of a Stirling cooler. The system has one piston at ambient temperature T a and one piston at low temperature T L. The basic type of Stirling-type cooler is depicted in Fig.1. It consists of (from left to right): a piston; a compression space and heat exchanger (all at ambient temperature T a) a regenerator; a heat exchanger
