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

Radiator Design

Radiator Design

The rational design of radiators to meet the requirements of maximum cooling capacity with minim head resistance and minimum weight under the velocity, pressure, and temperature conditions met with in flight requires considerable fundamental information regarding the laws of air flow and of heat dissipation in the honeycomb air-tube and vertical flat water-tube types of radiator construction used to-day.

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

More on Your Car’s Water Pump

The water pump in a car engine isn’t a complicated piece of machinery, despite its vital importance to the car’s ability to run efficiently without breaking down. Its role is to circulate water and coolant around the engine in order to keep its overall temperature, especially around the cylinder head and engine block, as low as possible when it is running. The higher the load on the engine, the more coolant will be circulated around it in order to deal with the greater levels of heat being produced. Continue reading

Aluminum Radiator Technical Information

Aluminum Radiator Technical Information

Tubes are the primary source of cooling. A radiators cooling capacity is governed by a number of factors. Most important are the tubes, the primary source of cooling. Heat dissipates from the coolant (water and antifreeze) through the tube wall (primary), then through the fins (secondary). 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

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
