The use of liquids in the process of heat transfer is a vital and indispensable method of cooling in several different industries. When picking the best heat transfer fluid for a specific cooling system, there are certain factors to consider, including compatibility, performance, as well as cost and maintenance.

 

For the most part, water naturally comes with very good heat transfer properties, which is why it's not that surprising that industries use it as the standard for comparison to the other types of coolants. Aside from having no flash point, water has far better properties like a high specific heat of 4,200 J/kgK, not to mention the fact that it has low viscosity. But one problem though is that it has a significantly narrow range of operation since liquid temperatures will expose plain water to boiling or freezing quite easily.

 

Meanwhile, it is very important to consider as well the suitability of a particular type of fluid to be used over the range of operating temperatures. For instance, the fluid's phase transitions, or its boiling and freezing tendencies must be considered, as well as the chemical breakdown of the chemistry of the fluid. The same holds true for the diminishment of the lubricating and heat transfer properties of the fluid. Get more info at this website!

 

You have to understand that the freezing state of a fluid will correspond to the substantial diminishing of heat transfer on a specific surface. Boiling on the other hand can become a risk for systems which aren't particularly designed to withstand over-pressure in the fluid containment.

 

Based on material compatibility meanwhile, stainless steel, especially 300 series stainless steel, is inert against majority of heat transfer liquids. This is primarily attributed to the nature of the chromium oxide passivation layer that covers the surface of these types of steels.

Aluminum, along with its alloys, are naturally considered as having good thermal conductivities. But the problem with aluminum is that it is very susceptible to corrosion. The fact is even with a glycol solution combined with distilled water, there is a tendency to form acidic compounds under oxidation; hence the possibility of causing corrosion to wet surfaces and the formation of organic acid products. The way to solve this problem is by adding corrosion inhibitors to the fluid or maybe the application of surface treatments to wet surfaces like that of anodized aluminum.

 

Finally, copper as well as copper nickel alloys are known to have very good resistance against corrosion as well as resistance to biological growth. Nonetheless, they are similar to aluminum in such a way that there's a need to use corrosion inhibitors to prevent the likelihood of acidic corrosion, go here!
