Thrust chamber cooling system is an important issue in liquid missile systems. In this paper, two more applicable systems, that is, regenerative and radiation cooling systems are studied. Regenerative cooling systems, which are mostly used in high pressure thrust chambers, are normally in two forms, tubular wall structure and double wall structure. Tubular structure has mostly a square form str...
This paper presents experimental results of an inherently safe liquid cooling system. A test rig is operated at Hamburg University of Technology in order to prove the concept and gather first data for electronics cooling in modern civil aircraft. The cooling system uses a dielectric working fluid for the natural circulation in a looped thermosyphon operating in both oneand two-phase mode. First...
In this white paper, the warm water direct liquid cooling solution implementation in the CCS cluster solution is described. First, literature review of a range of direct liquid cooling solutions implemented in various competing vendors and their pros and cons are briefly presented. Design choices of datacenter cooling water distribution mechanisms (single loop vs primary/secondary loops), types...
Carbon nanotubes (CNTs) are one of the most valuable materials with high thermal conductivity (2000 W/m · K compared with thermal conductivity of Ag 419 W/m · K). This suggested an approach in applying the CNTs in thermal dissipation system for high power electronic devices, such as computer processor and high brightness light emitting diode (HB-LED). In this work, multiwalled carbon nanotubes ...
Wepresent a simple layout of a fast cooling system for liquids in sealed containers utilizing the large temperature gradients of cold nitrogen gas. Our system is optimized for about 20 cylindrical containers of 500 cm, but the setup allows for simple upand down-scaling aswell as the use of arbitrary containers.We have characterized the cooling performance of our system experimentally for temper...
A standard air cooled data center is a rare phenomenon. Generally each one is individually designed, with hundreds of different component combinations. They can also be energy hogs. Cooling system power consumption in older data centers is typically 100% or more of the IT load. While energy efficiency has improved recently and Power Utilization Effectiveness (PUE) values – the ratio of total en...
This paper presents an in-depth system-level experimental analysis comparing air-cooled and liquid-cooled commercial off-the-shelf (COTS) electric motors. Typically, liquid-cooled electric motors are reserved for large, expensive, high-end applications where the design of the motor’s electromagnetic components are closely coupled to its cooling system. By applying liquid cooling to a pre-existi...
