Heat transfer fluids and thermal oils are used to carry thermal energy in process heating, metal working, and machine cooling applications. There are several types of products. Circulating coolants, chiller fluids, anti-freezes, and refrigerants are used to transfer heat or provide cooling within machinery, process equipment or combustion engines. Hot oils, heater oils, and other thermal fluids are used to provide or transfer heat to a region near machinery or process equipment. Typically,...

Applications and UseTop

Q:
What are some of the applications you have used heat transfer fluids and thermal oils for?
16 answers
Answers:
For cooling my own computer with my own designed soundless system over ten years ago. Upgrading today similar systems and other similar purpose system. Trying to find adequate low cost heat transfer paste substance for building an developing hot water solar system for everyone in DIY projects. Substance as such, that will allow high thermal conductivity between cooper pipes and aluminum plate fins, and inhibit electro-corrosion among metals, still not expensive for people in redevelopment countries. High W/mK.
