A coolant is a fluid which flows through or around a device to prevent its overheating, transferring the heat produced by the device to other devices that use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, and chemically inert, neither causing nor promoting corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
While the term coolant is commonly used in automotive and HVAC applications, in industrial processing, heat transfer fluid is one technical term more often used, in high temperature as well as low temperature manufacturing applications. Another industrial sense of the word covers cutting fluids.
The coolant can either keep its phase and stay liquid or gaseous, or can undergo a phase transition, with the latent heat adding to the cooling efficiency. The latter, when used to achieve below-ambient temperature, is more commonly known as refrigerant.
Air is a common form of a coolant. Air cooling uses either convective airflow (passive cooling), or a forced circulation using fans.
Time came around and I was in need
You came by my side, all my troubles to ease
You collected my heart, healing the past
You'll never lay down [unverified] and I can count on you
We all speak well of a bridge that carries us over
Over safe
The art of compromise has surely been our greatest strength
Our greatest strength
When someone pretends to circle your friend
And finds, he's [unverified] betraying you 'fore it all ends
A bittersweet chain, that'll always remain
So don't let illusions get the better of you
We all speak well of a bridge that carries us over
Over safe
The art of compromise has surely been our greatest strength
Our greatest strength
Love is to share where words can't compare
Love is desire, so full of fire
We all speak well of a bridge that carries us over
Over safe
The art of compromise has surely been our greatest strength
Our greatest strength
We all speak well of a bridge that carries us over
Over safe
The art of compromise has surely been our greatest strength
