Liquid Cooling of Compute System
Journal of Electronic Packaging, 2019The continued demand for increasing compute performance results in an increasing system power and power density of many computers. The increased power requires more efficient cooling solutions than traditionally used air cooling. Therefore, liquid cooling, which has traditionally been used for large data center deployments, is becoming more mainstream.

Liquid cooling of turboalternators
Electrical Engineering, 1947It is at least as large a step from hydrogen to liquid cooling as it was from air to hydrogen cooling of large turboalternators. A method of construction for liquid-cooled machines is difficult but the advantages to be gained by it are many and include improved temperature conditions, elimination of corona, and winding for higher voltages.

Liquid Helium-Cooled Bolometers
1972High responsivity, large surface infrared bolometers have been constructed using three types of thermo-sensitive elements : carbon resistors, germanium, and silicon. All three types have been successfully operated in the liquid helium range (1.5 to 4.2 K) as part of ground-based or balloon-borne experiments using the cryostats described in a separate ...

Liquid Cooling of Power Thyristors
IEEE Transactions on Industry Applications, 1972A method of determining a given heat exchanger's thermal properties from the characteristics of the cooling medium is discussed. A test method is presented with an example which helps to clarify the results. It is concluded from running tests using three to four different liquids that heat exchanger thermal performance data can be derived for liquids ...

LIQUID COOLING FOR IMPROVED LED PERFORMANCE
2013The main issue concerning the power LEDs is the thermal power generated during operation, which increases the junction temperature affecting the operating characteristics of the power LED and casing the reduction of: the useful life of the components, the luminous flux, the light efficiency and the forward voltage.
