Reminding You About How Your Radiator Works

Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Continue reading

Cooling System Design Specification and Notes

Consider what kind of debris might get drawn into the cooling system by the fan during operation. Such as grass clippings on a lawn mower, or textile products on a fork lift that’s working in a mill. The cleaner the environment the more economical the radiator core. Continue reading

Aluminum Radiator Technical Information

In the beginning, there was the copper brass radiator. Copper brass construction seemed the obvious choice for the first radiators because of superior heat conductivity Continue reading

Seven Car Radiator Myths

Seven Car Radiator Myths

It seems that everyone with a vehicle has an opinion on car radiators, engine cooling, truck radiators and cooling systems. People argue about coolant types. And car radiator manufacturers. Materials for truck radiators (including the evern popular aluminum radiator). They argue about radiator sizes, and so on. Continue reading

Internal combustion engine cooling

Internal combustion engine cooling

Heat engines generate mechanical power by extracting energy from heat flows, much as a water wheel extracts mechanical power from a flow of mass falling through a distance. Engines are inefficient, so more heat energy enters the engine than comes out as mechanical power; the difference is waste heat which must be removed. Internal combustion engines remove waste heat through cool intake air, hot exhaust gases, and explicit engine cooling. Continue reading

An engine provides mechanical energy from an air/fuel mixture with an efficiency between 20 and 45%. The rest flows in kinetic and heat energy in exhaust gases and in heat energy through metallic bodies due to the frictions. In this context, the cooling system must allow the engine to give its best performance, ensure the durability of this performance and ensure engine reliability by guaranteeing an acceptable level of thermo-mechanical stresses in any point of the engine.

What’s A Heater Core?

What’s A Heater Core?

A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle’s engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface for heat transfer to air that is forced past them, by a fan, thereby heating the passenger compartment. Continue reading

Air Cooling And Liquid Cooling

Air Cooling And Liquid Cooling

Internal combustion engine cooling uses either air or a liquid to remove the waste heat from an internal combustion engine. For small or special purpose engines, air cooling makes for a lightweight and relatively simple system. The more complex circulating liquid-cooled engines also ultimately reject waste heat to the air, but circulating liquid improves heat transfer from internal parts of the engine. Continue reading
