An expansion tank, also known as "overflow bottle", is also used in the cooling system of most internal combustion engines, to allow the coolant, such as antifreeze, and the air in the system to expand with rising temperature and pressure. The tank is also called a "coolant recovery tank", since it prevents venting and permanent loss of coolant ...
As the coolant system pressure increases with a rise in temperature, it will reach the point where the pressure relief valve allows excess pressure to escape. This will stop when the system temperature stops rising. In the case of an over-filled radiator (or header tank) pressure is vented by allowing a little liquid to escape.
In many types of processes, combustion is used to generate heat, and the recuperator serves to recuperate, or reclaim this heat, in order to reuse or recycle it. The term recuperator refers as well to liquid-liquid counterflow heat exchangers used for heat recovery in the chemical and refinery industries and in closed processes such as ammonia-water or LiBr-water absorption refrigeration cycle.
Coolant oil may be limited to cooling objects under approximately 200–300 °C, otherwise the oil may degrade and even leave ashy deposits. Pure water may evaporate or boil, but it cannot degrade, although it may become polluted and acidic. Water is generally available should coolant need to be added to the system, but oil may not be.
The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...

A thermal energy storage tank is a naturally stratified thermal accumulator that allows the storage of chilled water produced during off-peak time, to use this energy later during on-peak time to chill the turbine inlet air and increment its power output. A thermal energy storage tank reduces operational cost and refrigerant plant capacity. [20]
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
