Heat Transfer Performance of Radiator Heating System with Alternative Heat Transfer Fluids

2020
Heat transfer fluids (HTFs) are an essential heat transport medium in many wet heating and cooling systems. They carry Heat from the generation source to the place where it is being used. Therefore, HTFs should have the capability of carrying Heat efficiently. The ability of HTFs to carry out the maximum amount of Heat with minimum loss is dependent on

Influence of Irreversible Heat Transfer on Heat Engine-Driven Heat Pump Performance

Thermodynamics and the Design, Analysis, and Improvement of Energy Systems, 1995
Abstract The coupling of a heat engine with a conventional compression heat pump is considered. Classical thermodynamics would provide, as upper performance limit of such a system, the one achieved in the case in which Prime Mover and Heat Pump both operate according to a Carnot cycle. Finite-time thermodynamics, utilizing

Comparison of Heat Transfer Performance Between Smooth and Enhanced Heat Transfer Tubes

ASME 2019 6th International Conference on Micro/Nanoscale Heat and Mass Transfer, 2019
Abstract Heat transfer enhancement is an important factor in obtaining energy efficiency improvements in all heat transfer applications. A numeric study was performed that compares the performance of heat exchangers using the Vipertex enhanced heat transfer tubes (model 1EHT) to the performance of heat exchangers that use smooth surface ...

Heat transfer performance of porous titanium

Journal of Iron and Steel Research International, 2017
Porous titanium fibre materials with different structural parameters were prepared by vacuum sintering method. The thickness, porosity and wire diameter of prepared materials were investigated to understand the effects of structural parameters on pool heat transmission performance of titanium fibre porous material.

Microchannel Heat Sink with Enhanced Heat Transfer Performance by Laser Process

2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018
The heat transfer performance of microchannel heat sink which is fabricated by Nanosecond laser machining (NLM) is investigated. The experiment data suggest that the heat transfer performance of microchannel heat sink (MHS) processed by NLM is superior to that by Deep Reactive Ion Etching (DRIE).

Nanoengineering Heat Transfer Performance at Carbon Nanotube Interfaces

ACS Nano, 2009
Carbon nanotubes are superb materials for nanoscale thermal management and phononic devices applications, due to their extremely high thermal conductivity (3000-6600 W/mK) and quasi-one-dimensional geometry. However, the presence of interfaces between individual carbon nanotubes as found widely in nanocomposites, nanoelectronics, and nanodevices ...
